A plurality of pads (122) are arranged in the active area (AA) where scan lines (SL), data lines (DL), and high-potential voltage (VDD) supply are provided, and unit pixels containing the light-emitting device (130) are arranged in the pixel area (PA). As shown in FIG. 1, each unit pixel includes an anode electrode (132) connected to the drain electrode of the driving transistor (TD), and a light-emitting stack (134) formed on the anode electrode (132). The light-emitting stack (134) consists of a hole transport layer, an emission layer, and an electron transport layer sequentially or in reverse order laminated on the anode electrode (132), and a cathode electrode (136) is positioned opposite to the anode electrode (132) with the light-emitting stack (134) in between. The light-emitting stack (134) and bank encapsulation unit (140) are designed to prevent the infiltration of external moisture and oxygen into the delicate light-emitting device (130). The first inorganic encapsulation layer (142) is formed on the substrate (101) where the cathode electrode (126) is located closest to the light-emitting device (130). To restrict the fluidity of this organic encapsulation layer (144) during its formation, at least one outer dam (118) and one inner dam (108) are provided. As shown in FIG. 1, at least one outer dam (118) completely surrounds the active area (AA) where the light-emitting device (130) is located, and at least one inner dam (108) completely encircles the through-hole (120) positioned in the hole area (HA). At this juncture, the inner bezel area (BA) is situated between the hole area (HA) and the pixel area (PA). The bezel area (BA) includes the aforementioned inner dam (108), and then, through a photolithography process, source and drain electrodes (not shown), signal lines (106), and pad electrodes (122) are formed. Following this, the organic cover layer (112) on the pad electrodes (122) is removed through an etching process, thereby forming a pad contact hole (124). FIG. 2 presents a cross-sectional view of the organic light-emitting display device taken along lines "I-I'" and "II-II'" in FIG. 1.

Figure 1 illustrates a configuration diagram of a touch display device (100) according to the present embodiments, and Figure 2a depicts a display panel (110) according to these embodiments or the touch display device (100) based on the embodiments described herein, comprising a display panel (110), a data driving circuit (120), a gate driving circuit (130), and a touch data driving circuit (120) which operates to drive data lines disposed on the display panel (110). For example, during the display period, the data driving circuit (120) may supply data voltage to the data lines. The gate driving circuit (130) operates to drive gate lines disposed on the display panel (110). For instance, during the display period, the gate driving circuit (130) can sequentially supply scan signals to the gate lines. The touch sensing circuit (140) operates by using the touch sensors arranged on the display panel (110), providing a touch driving signal to the touch sensor corresponding to the driving electrode, and thus, the touch sensing circuit (140) provides the touch driving signal to the touch sensor, and the signal is received from the touch sensor supplied with the touch driving signal. The touch display device (100) according to the present embodiments employs an organic light-emitting diode (OLED) mechanism. Figure 5 demonstrates the parasitic capacitance (Cp) between the touch sensor (TS) and the second electrode (E2) within the touch display device (100) as per the embodiments, Figure 6 illustrates the electrode type touch sensor (TS) without an aperture, and Figure 7 illustrates an electrode type touch sensor (TS) with an aperture from the touch display device (100) examples. Each touch sensor (TS), i.e., each driving electrode (Tx) or sensing electrode (Rx), has a larger area than a single subpixel. Figure 8 shows mutual-capacitance based touch sensing in the touch display device (100) according to the embodiments. Referring to Figure 8, the touch sensors (TS) can be electrically connected to the touch sensing circuit (140) through these signal lines (TL). Figure 9 depicts the mutual-capacitance based touch sensing scenario in touch display device (100). For example, signals at locations t1, t2, t3, and t4 at the driving electrode (Tx) locations can be addressed, and the touch sensing circuit (140) supplies touch driving signals via the driving signal line (Lt) and receives signals via the sensing signal line (Lr). Figure 10 shows mutual-capacitance based touch sensing for the device, detailing mesh type touch sensors (TS) with openings (OA), in which two or more sub-electrodes (SE1, SE2, ?? forming a driving electrode (Tx) or sensing electrode (Rx) pass through contact holes in the insulating layer (1120). Meanwhile, pads (not shown) in the display panel (110) connect the touch sensing circuit (140) with the signal lines (TL) using two or more sub-electrodes. Figures 13 and 14 present the aperture region and the emitting region of the touch sensor (TS). Figure 15 demonstrates the multi-electrode structure and single wiring of signal lines for the touch sensor (TS). Referring to Figures 15 and 16, a plurality of signal lines electrically connects multiple touch sensors (TS) and touch sensing circuits (140). (2) On the first sub-electrode (SE1), driving bridge pattern (Bt), and first sub-wiring (SL1), an insulating layer (1120) is formed, electrically connecting the second sub-electrode (SE2) to the first sub-electrode (SE1) through a contact hole in the insulating layer (1120). Figures 17 and 18 showcase examples of enhanced sensitivity structures for touch sensors (TS) in the touch display device (100), while Figure 19 illustrates protection structures and Figure 20 depicts interlayer protection structures. Figure 21 demonstrates bridge pattern modifications, and Figure 22 showcases mutual-capacitance based touch sensing. Figures illustrate diverse scenarios ??Figure 25 shows self-capacitance based touch sensing. The touch sensing circuit (140) provides touch driving signals through signal lines (TL) and senses through these lines for self-capacitance based sensing, illustrated in Figure 27. Two or more sub-electrodes (SE1, SE2, ?? forming one touch sensor (TS) pass through contact holes in an insulating layer (1120), illustrating a touch panel configuration in the present embodiments. Figure 1 demonstrates the touch display device configuration per present embodiments. [0034]

The advantages and features of the present application, as well as the methods for achieving them, are described in detail with reference to the accompanying drawings and examples detailed below. The shapes, sizes, ratios, angles, numbers, etc., disclosed in the drawings for illustrating examples of the application are exemplary, and in interpreting the components of the present invention, they should be understood as including an error range unless it is explicitly stated otherwise. When describing positional relationships, expressions such as ?์ฎn?? ?์bove?? ?์želow?? ?์ญext to?? and so on, may be used for describing the positional relationship between two parts. First, second, etc., are used to describe various components, but these components are not limited by these terms. In describing the components of the present application, terms such as first and second can be used, but the application is not limited thereto. According to the present application, the display device covers both narrow displays such as LCM and LED modules and wider applications, with an example being a display panel employing a LED display panel that includes multiple gate lines and data lines. Furthermore, the display panel may further comprise a backing such as a metal plate attached to it. The individual characteristics of the examples of this application can be partially or entirely combined or recombined for technical purposes. Below, examples of the present application are observed through the attached drawings and examples, as follows. Figure 1 is a plan view illustrating a display device according to one example of the present application. Referring to Figure 1, the display device (100) may include a substrate (110), a pixel array layer (190), a display driving circuit unit (210), and a scan driving circuit unit (220). The substrate (110) acts as a base substrate and may be a flexible substrate, for example, a transparent polyimide. According to one example, the substrate (110) may be a glass substrate; for example, the substrate (110) may be made of silicon dioxide (SiO2) or aluminum oxide. The substrate (110) may contain a display area (AA) and a non-display area (NA). The display area (AA) is where images are displayed, surrounded by the edge of the substrate (110) that does not display images. The pixel array layer (190) comprises a thin-film transistor layer and an emissive element layer. The thin-film transistor layer includes thin-film transistors, and the display driving circuit unit (210) is connected to pad electrodes provided in the non-display area (NA) of the substrate (110) to drive the display system. Each of the multiple circuit films (211) has input terminals provided on one side that may be connected to a printed circuit board (215) through a film attachment process. Each of the multiple data driving integrated circuits (213) can be separately mounted on each circuit film (211). The printed circuit board (215) supports the timing controller (217), allowing passage of signals and power among the configurations of the display driving circuit unit (210). The timing controller (217) is mounted on the printed circuit board (215) and connected through a user connector provided on the printed circuit board (215). The scan driving circuit unit (220) may be provided in the non-display area (NA) of the substrate (110). Figure 2 is an enlarged view of area A in Figure 1. Referring to Figure 2, the substrate (110) can include a display area (AA) and a non-display area (NA), with the non-display area (NA) containing at least a plurality of sub-pixels (SP), each including an emission area (EA). In particular, each of the plurality of sub-pixels (SP) can be defined as the smallest unit area emitting light. A plurality of unit pixel contact pads (CP) may be arranged on a planarization layer (160) in the cathode contact area (CCA). Specifically, the contact pad (CP) can be configured such that a plurality of emission areas (EA) are grouped in a predetermined unit, and pad electrodes (PE) of a predetermined unit can be formed on a passivation layer (150) in the pad area (PA). The anode electrode (AE) and contact pad (CP) may be structured as part of these units. Figure 3 is another enlarged view of area A in Figure 1. Here, the display device of Figure 3 is similar to the display device of Figure 2 in terms of the cathode contact area configuration. Referring to Figure 3, the substrate (110) may include a display area (AA) and a pad area (PA), with the display area (AA) being particularly configured to allow the cathode contact area (CCA) to correspond to each of the multiple emission areas (EA). For example, Figure 4 presents a sectional view along the cutting line I-I' of Figure 2 in a display device according to the first embodiment of this application. Figure 5 presents view C of Figure 4. Referring to Figures 4 to 6, the display device (100) may comprise a substrate (110), a light shielding layer (LS), a buffer layer (120), a thin-film transistor (T), and a gate. The substrate (110) serves as a base substrate and can be a transparent flexible substrate capable of bending or flexing. According to one example, the substrate may be a glass substrate; for example, it can comprise silicon dioxide (SiO2) or aluminum oxide. The light shielding layer (LS) can be situated on the substrate (110) so as to overlap the thin-film transistor (T). For instance, the light shielding layer (LS) can be formed on the substrate. The buffer layer (120) can be arranged on the substrate (110) and the light shielding layer (LS). According to one example, the buffer layer (120) can be formed of a plurality of inorganic films. The thin-film transistor (T) can be arranged on the buffer layer (120) so as to overlap each of the multiple emission areas (EA). According to one example, the active layer (ACT) is formed in the display area (AA) of the substrate (110), attached onto the buffer layer (120). According to one example, the active layer (ACT) may comprise a channel area (ACT1) and a source/drain area (ACT2). The gate insulating film (130) can be established on the active layer (ACT), and the gate electrode (GE) may be established on the gate insulating film (130). The gate electrode (GE) may be provided with the gate insulating film (130) interposed therebetween. The interlayer insulating film (140) can be established on the gate electrode (GE). Furthermore, the interlayer insulating film (140) can be established on the gate insulating film (130). The source electrode (SE) and drain electrode (DE) may be arranged spaced apart from each other on the interlayer insulating film (140). The passivation layer (150) can cover the thin-film transistor (T). Specifically, the passivation layer (150) can be overlapped on the interlayer insulating film (140), and the planarization layer (160) can be disposed on the substrate (110) to encapsulate the thin-film transistor (T) arranged in the display area (AA). The light-emitting element (E) can be arranged on the planarization layer (160) in the display area (AA) and can be electrically connected to the thin-film transistor (T). The anode electrode (AE) can be located at openings of each of the plurality of sub-pixels (SP). Specifically, the anode electrode (AE) can be placed on the planarization layer (160) in the display area (AA) and can be electrically connected to the source electrode (SE) of the thin-film transistor (T). The first anode electrode (AE1) may be arranged at the uppermost of the anode electrode (AE). Specifically, the first anode electrode (AE1) may be placed over the second anode electrode (AE2), which can be arranged below the first anode electrode (AE1). Specifically, the second anode electrode (AE2) can be made of reflective metal. For example, the second anode electrode (AE2) can use a reflective metal, with its thickness proportionately greater than that of the first and fourth metal films (CP1, CP4). For instance, the first and fourth metal films may be thinner. The third anode electrode (AE3) can be placed below the second anode electrode (AE2). Specifically, the third anode electrode (AE3) can be placed to reflect faster etching rates compared to the second anode electrode (AE2). The fourth anode electrode (AE4) can be established on the planar surface of the planarization layer (160). Specifically, the level of oxidation for the fourth anode electrode (AE4), defined similarly as materials used for the second and third anode electrodes, can vary. The light-emitting layer (EL) can be formed on the anode electrode (AE) and the contact pad (CP). The light-emitting layer (EL) may not be distinctly divided by pixel areas. The cathode electrode (CE) may be formed overall without separation according to pixel areas and can be in direct contact with the contact pad (CP) in regions where the light-emitting layer is absent. Specifically, the cathode electrode (CE) may include a bent part (BNT) that directly contacts the side contact part (SC). Specifically, the cathode electrode (CE) can be spaced apart from the pad electrode (PE) on the passivation layer (150). According to one example, the hobby (B) can be situated on the planarization layer (160) in the display area (AA) to encapsulate the plurality of emission areas (EA) and the cathode contact area (CCA). The sealing layer (170) can cover each of the openings of the plurality of sub-pixels (SP) and the hobby (B). According to one example, the sealing layer (170) may use the same material as one of the auxiliary power lines, such as the first auxiliary power line (EVSS1), electrically connecting to the auxiliary wiring (AL) on the same layer formed by the gate electrode (GE). Similarly, the second auxiliary power line (EVSS2) electrically connects to the auxiliary wiring (AL) using the same material, with similar properties as the light shielding layer (LS), connecting contact pads (CP) electrically through auxiliary wiring (AL). The auxiliary wiring (AL) can be arranged on the planarization layer (160) to space apart from the source electrode (SE) and the drain electrode (DE). The contact pad (CP) can be arranged on the planarization layer (160) of the cathode contact area (CCA) and can be electrically connected to the auxiliary wiring (AL). The first metal film (CP1) can be placed at the uppermost of the contact pad (CP). The first metal film (CP1) can be situated below the light-emitting layer (EL). According to one example, the first metal film (CP1) may use a transparent conductive material such as ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide). The second metal film (CP2) can be provided below the first metal film (CP1). Specifically, the second metal film (CP2) can utilize reflective metals. For example, the second metal film (CP2) may use reflective metals like Molybdenum, with its thickness being larger compared to the first metal film (CP1), ranging from 100 nanometers to the greater thickness of the second metal film. The third metal film (CP3) can be arranged beneath the second metal film (CP2). Specifically, the third metal film (CP3) can be arranged with a faster etching rate than the second metal film (CP2), further placed with its segment distinguished from the reflection properties of the second metal film. The contact pad (CP) can comprise a side contact part (SC) connecting with the cathode electrode (CE). Specifically, the light-emitting layer (EL) should maintain non-contact with the intermediate section (SC_M) of the side contact part (SC). According to one example, the anode electrode (AE) and contact pad (CP) forming material can be placed on the planarization layer (160) for subsequent patterning. However, according to one example in this application, if the etching rate of the third metal film (CP3) is faster than that of the second metal film (CP2), the third metal film (CP3) will be etched beneath the second metal film (CP2) hastily. In Figures 6a to 6c, the intermediate section (SC_M) of the side contact part (SC) can exhibit a concave form as based on the thickness of the contact pad (CP). Therefore, the light-emitting layer (EL), arranged with a canopy style at the upper portion of the contact pad (CP), establishes with the intermediate section (SC_M) of the side contact part (SC). In Figure 6a, both the second and third metal films (CP2, CP3) can maintain the same thickness, with the upper and side surfaces of the second metal film (CP2) demonstrating rounded features. Figure 6b shows the second and third metal films (CP2, CP3) to possess matching thickness, alongside upper and side surfaces retaining these rounded characteristics. However, Figure 6c ensures the third metal film (CP3) achieves greater thickness compared to the second metal film (CP2), complemented with distinguishing edges in response to higher etching rates. The cathode electrode (CE) comprises a bent portion (BNT) directly contacting the side contact part (SC). Specifically, the cathode electrode embodying, along its structural integration, are contingent designs agreeable to alternative formats, ensuring modifications in answerability to reflective material adjustments.

Hereinafter, with reference to the accompanying drawings, preferred embodiments according to the present invention will be described in detail. Throughout the specification, the pixel circuit and the gate shift register formed on the substrate of the display panel in the present invention refer to an n-type MOSFET (Metal Oxide). FIG. 1 shows an organic light emitting display device including a gate shift register according to an embodiment of the present invention. Referring to FIG. 1, the organic light emitting display device according to the present invention comprises a display panel (100), a data driving circuit, a gate driver (130,150), and the display panel (100) includes a plurality of data lines and a plurality of gate lines crossing each other, with pixels formed in a matrix at each intersection. The data drive circuit includes a plurality of source drive ICs (120). The source drive ICs (120) are connected to a timing controller, and the gate driver (130,150) is connected to the gate lines of the display panel (100) via a level shifter. The level shifter (150) receives clock signals (CLKs) of TTL (Transistor-Transistor-), and the gate shift register (130) can be directly formed on a lower substrate of the display panel (100) in a GIP (Gate In Panel) method. The timing controller (110) receives image data (RGB) from an external host system through various known interfaces. The timing controller (110) receives vertical synchronization signal (Vsync), horizontal synchronization signal (Hsync), and data enable signal including gate timing control signals such as start signal (VSP) and shift clocks (CLKs). The data timing control signal includes a source sampling clock (SSC), a source output enable signal (Source). FIG. 2 shows an inter-stage connection configuration of the gate shift register included in the gate driver of FIG. 1. Referring to FIG. 2, the gate shift register according to an embodiment of the present invention describes a plurality of stages connected dependently to each other. The stages (STGn~STGn+3) independently generate scan control signal (SCT(n)~SCT(n+3)) and carry signal (CRY(n)~CRY(n+3)). Although not shown in the drawings, the stages (STGn~STGn+3) may further generate a sensing control signal before the gate line. The scan control signal (SCT(n)~SCT(n+3)), carry signal (CRY(n)~CRY(n+3)), and sensing control signal disclosed in patent publication 10-2019-0069188 include a global start signal (VSP), shift clocks (CLKs), and a global reset signal commonly supplied to the stages (STGn~STGn+3). Each stage (STGn~STGn+3) operates the node Q according to a pre-stage carry signal applied to the start terminal for each frame. Each stage (STGn~STGn+3) operates the node Q according to a post-stage carry signal applied to the reset terminal for each frame. A plurality of shift clocks (CLKs) may be supplied to each stage (STGn~STGn+3). The shift clocks (CLKs) may be driven in an overlapping manner to ensure sufficient charge time for high-speed driving. To simplify the inter-stage connection configuration (STGn~STGn+3) and reduce the bezel area, the shift clocks (CLKs) are supplied. Each stage (STGn~STGn+3) may receive power voltage (PS) from an external power supply (not shown). FIG. 3 depicts a circuit diagram showing a stage according to an embodiment of the present invention. Additionally, FIG. 4 shows a pixel connecting to the stage of FIG. 3. FIG. 3 shows the nth stage (STGn) that outputs nth gate signal (SCT(n)) and nth carry signal (CRY(n)). Referring to FIG. 3, stage STGn includes an input unit BK1, inverter unit BK2, output buffer BK3, and stabilization unit BK4. Input unit BK1 responds to a pre-stage carry signal CRY(n-3) input through the start terminal to raise the potential of node Q(n) to high. For this purpose, input unit BK1 comprises a plurality of transistors (T1, T2). Transistor T1 activates in response to the pre-stage carry signal CRY(n-3). Inverter unit BK2 charges and discharges node Qb(n) in opposition to node Q(n). Inverter unit BK2 operates according to the potential of node N1. To achieve this, inverter unit BK2 includes a plurality of transistors (T4, T5, T6). Transistor T4 connects to node N1 in inverter unit BK2. While node Q(n) is activated, inverter unit BK2 deactivates node Qb(n) to low potential power voltage GVSS. For this purpose, inverter unit BK2 includes additional transistors (T7, T8). Transistor T7 connects to node Q(n). Output buffer BK3 outputs scan shift clock SCCLK(n) from output node N2 when the potential of node Q(n) rises to the boosting level. For this purpose, output buffer BK3 includes first and second pull-up transistors (T9A, T10A) and a capacitor Cx. The stabilization unit BK4 applies low potential power voltage GVSS to nodes Q(n) and output nodes N2, N3 while node Qb(n) is active. For this purpose, stabilization unit BK4 includes transistor T3, and first and second pull-down transistors (T9B, T10B). The scan control signal SCT(n) output from such a stage STGn is transmitted to the pixel (PIX) through gate line GLn, as shown in FIG. 4. The pixel (PIX) in FIG. 4 operates in the basic mode for image display. In the basic mode, pixel (PIX) responds to the scan control signal. Accordingly, pixel (PIX) may include an OLED, a driving TFT (DT), a switch TFT (ST1), and a storage capacitor (Cst). During the programming period, switch TFT (ST1) turns on according to scan control signal SCT(n). The scan shift clock SCCLK is used for pixel display. FIG. 5 is a circuit diagram showing another stage according to another embodiment of the present invention. Furthermore, FIG. 6 shows a pixel connecting to the stage of FIG. 5. Since the stage of FIG. 5 connects to the pixel as shown in FIG. 6, it is configured to output the sensing control signal SET(n) with a sensing shift clock. Compared to FIG. 3, the output buffer BK3 of FIG. 5 further includes a configuration for outputting the sensing control signal SET(n). Comparing FIG. 3 with FIG. 5, the stabilization unit BK4 comprises a third pull-down transistor (T11B) not included in FIG. 3's design. The scan control signal SCT(n) output from such a stage STGn is transmitted to the pixel (PIX) through gate line GL1n as shown in FIG. 6. The pixel (PIX) in FIG. 6, compared to FIG. 4, includes a second switch TFT (ST2), and the source drive IC (120) in FIG. 6 operates with the pixel (PIX) during the basic mode comprising a programming period and an emission period. In the programming period, the first switch TFT (ST1) turns on, driving the data voltage (Vdata) on the data line (DL). -11- The sensing mode targeting the pixel (PIX) and sensing circuit in FIG. 6 incorporates a programming period and a sensing period. The programming period operation in sensing mode is similar to the basic mode. During the programming period, switch SW1 turns on, and switch SW2 turns off. During the sensing period, the first switch TFT (ST1) and switch SW1 turn off while the second switch TFT (ST2) and switch SW2 turn on. Meanwhile, in the basic mode, switch TFT (ST1) turns on during the programming period according to the scan control signal SCT(n). The scan shift clock SCCLK operates for pixel display. FIG. 7 shows an exemplary arrangement of clock wirings connecting to stage elements like those in FIG. 3. Moreover, FIG. 8 elaborates on the configuration shown in FIG. 7. Referring to FIGS. 7 and 8, the gate shift register comprises stages (SGT1~STG7) with carry shift clocks of different phases. To reduce the number of clock wirings connected to stages (SGT1~STG7), the number of shared carry clock wirings (12,14,16) is configured. The odd stages (STG1,STG3,STG5, etc.) receive odd scan shift clocks (SCCLK1, SCCLK3, SCCLK5) and excellent scan shift clocks to neighboring clock wirings shared among stages (SGT1~STG7). FIG. 9 illustrates another exemplary arrangement of clock wirings connecting to stage elements like those in FIG. 5. Additionally, FIG. 10 provides details on the configuration shown in FIG. 9. Referring to FIGS. 9 and 10, the gate shift register comprises stages (SGT1~STG7) with carry shift clocks of different phases. To reduce the number of clock wirings connected to stages (SGT1~STG7), the number of shared carry clock wirings (12,14,16) is configured. The number of sensing clock wirings (31~36) is configured to match the number of scanning clock wirings (21~26), and the sensing shift clock lines are compared to reduce the total wiring for both scanning and carry operations. The shared carry clock wirings (12,14,16) holding carry shift clock lines are placed adjacent to each other and connected between stages (SGT1~STG7). FIG. 11 exemplifies a different arrangement of clock wirings connecting to stage elements like those in FIG. 5. Additionally, FIG. 12 further details the configuration shown in FIG. 11. Referring to FIGS. 11 and 12, the gate shift register comprises stages (SGT1~STG7) with carry shift clocks of different phases. To minimize the number of clock wirings, the configuration is set. During this time, scanning and carry shift clocks are paired to similar phases for optimal operation. Shared carry clock wirings (12,14,16) are aligned and connected to stage elements. FIG. 13 illustrates yet another arrangement of a clock wiring example connecting to stage components similar to FIG. 5. Additionally, FIG. 14 complements the layout shown. Referring to FIGS. 13 and 14, the gate shift register comprises stages (SGT1~STG7) with differently phased carry shift clocks. To minimize the number of clock connections, shared sensing clock lines (32,34,36) and similar structures are established. In this regard, odd scan shift clocks paired with odd carry shift clocks are synchronized for unified phases. Shared carry clock lines (11~16) have an established configuration for both scanning and carry functionalities. FIG. 15 depicts a modified example of FIG. 7 aiming to reduce coupling effects between clock wirings. Furthermore, FIG. 16 provides detailed insights into the configuration shown in FIG. 15. Referring to FIGS. 15 and 16, the gate shift register minimizes signal distortion due to coupling more effectively than FIG. 7's configuration. Applying signals with identical phases to neighboring clock wirings reduces rising and falling instances between these lines. FIG. 17 presents a modified example of FIG. 9 designed to minimize coupling effects between clock wirings. Additionally, FIG. 18 outlines the configuration shown in FIG. 17. By considering FIGS. 17 and 18, the gate shift register optimizes coupling-induced signal distortion better than the configuration in FIG. 9, maintaining effective signal transmission by synchronizing phase in shared carry clock lines (12,14,16). FIG. 19 demonstrates a modified example of FIG. 11 that addresses coupling effects between clock wirings, and FIG. 20 provides an illustrative continuation. Referring to FIGS. 19 and 20, the gate shift register further optimizes coupling-related distortions. Shared carry clock lines (12,14,16) have their synchronization phase configured to minimize disruptions between signals and to facilitate effective rising and falling occurrences. Additionally, FIG. 21 shows an arrangement similar to FIG. 13 with reduced coupling effects, and FIG. 22 extends the description. From FIGS. 21 and 22, the gate shift register tailors configurations to align signal phases coherently. Subsequently, shared clock wirings with appropriate phase optimization are established to enhance performance, facilitating coupling-resistant designs. In summary, the present invention reduces the number of carry and/or sensing clock wirings to implement narrow bezels. Moreover, the invention strategically arranges clock wirings supplying clock signals of identical phases adjacently to minimize coupling effects. Through the above descriptions, those skilled in the art can perform various modifications and adaptations without departing from the spirit of the invention. 100: Display Panel 110: Timing Controller.

FIG. 3 illustrates a schematic view of an organic light-emitting display device according to one embodiment of the present invention. FIG. 4 depicts each pixel of FIG. 3. As illustrated in FIG. 3, the organic light-emitting display device according to one embodiment of the present invention includes a display panel (100), and the display panel (100) includes a display area comprising a plurality of pixels (P). Gate lines (GL1~GLm) and data lines (DL1~DLn) are arranged to intersect each other, thereby corresponding to the plurality of pixels (P). A gate driver (300) supplies scan signals to the plurality of pixels (P) through the gate lines (GL1~GLm), and when operating in a driving mode to display an image, the gate driver (300) supplies scan signals for each image frame. Also, during a sensing period, the gate driver (300) operates in a sensing mode to sense the deterioration state of each pixel. The data driver (200) supplies data signals to the plurality of pixels (P) through the data lines (DL1~DLn), and when operated in driving mode, supplies scan signals to each gate line (GL) during each vertical period. Furthermore, the data driver (200) supplies sensing signals to each sensing signal line (SL) during the sensing period as standard voltage lines are activated. A timing controller (400) switches each of the gate driver (300) and data driver (200) between driving mode and sensing mode according to timing signals (TSS). The timing controller (400) may also drive both the gate driver (300) and the data driver (200) in sensing mode. A deterioration compensation unit (500) supplies compensation data to the data driver (200) to compensate for the deterioration state of each pixel (P), using the stress generated from counting the input data (Idata) corresponding to each pixel (P). The data signals (Vdata) provided by the data driver (200) to the plurality of pixels (P) are compensated by the deterioration compensation unit (500). As illustrated in FIG. 4, each pixel (P) comprises an organic light-emitting device (OLED) and a pixel circuit (PC) driving the OLED, where the pixel circuit (PC) includes a first switching TFT (ST1), a second switching TFT (ST2), a driving TFT (DT), and a storage capacitor (Cst). The first switching TFT (ST1) connects between a gate line (GL), a data line (DL), and a first node (n1). The driving TFT (DT) connects a first node (n1), a driving power line (PL), and a second node (n2). The storage capacitor (Cst) is connected between the gate and drain electrodes of the driving TFT (DT), i.e., between the first node (n1) and the second node (n2). The OLED is connected between the second node (n2) and a second driving power source (VSS), driving the TFT (DT) to supply the data line (DL) data through the turned-on first switching TFT (ST1) to the first node (n1). The second switching TFT (ST2) connects between a sensing signal line (SL), a standard voltage line (RL), and the second node (n2). As explained, the data driver (200) is controlled by the timing controller (400 in FIG. 3) to operate in driving mode and sensing mode. The data driver (200) includes a data signal generator (210), a sensing data generator (230), and a switching unit (240). The data signal generator (210) generates data signals of voltage levels corresponding to input data (Idata). Exemplarily, the switching unit (240) includes a first and a second switch (240a, 240b), where the first switch (240a) transmits the data signal (Vdata) to the data line (DL) in driving mode and in sensing mode enables the second switch (240b) to transmit a second reference voltage (Vpre_r) to the reference voltage line (RL). During the sensing voltage charging period of sensing mode, the second switching TFT (ST2) of each pixel (P) turns on, connecting to the reference voltage line (RL). As shown in FIG. 5, the deterioration compensation unit (500) includes a data counting unit (510), a deterioration prediction unit (520), and a deterioration area detection unit (530). The data counting unit (510) counts the input data (Idata) corresponding to each pixel to generate accumulated data (Adata) for each pixel. Based on the accumulated data (Adata) of each pixel, the deterioration prediction unit (520) yields predicted values corresponding to each pixel's deterioration state. The deterioration area detection unit (530) detects at least one deterioration area within the display area based on the stress data (MSdata) for each pixel. By way of example, the detection unit (530) calculates deterioration threshold data using the maximum stress data for each horizontal line and identifies which horizontal lines exhibit maximum stress data exceeding the threshold. The first compensation data generator (550) uses sensing data received from the sensing control unit (540) and stress data for pixels in each deterioration area to generate compensation data. The first generator (550) corrects stress data and generates compensation data based on the differences between sensing data and corresponding stress data received. The deterioration compensation unit (500) predicts deterioration based on stress data. The methods further extend to counting input data (Idata) corresponding to each pixel and detecting at least one deterioration area per pixel's stress data, where the counting unit (510) counts and predicts each pixel's deterioration state. Based on scattering configurations of maximum stress data across multiple horizontal lines, the detection unit (530) selects horizontal lines exceeding critical data, and the sensing controller (540) randomly selects two or more horizontal lines for data sensing generation under its supervision. Data for areas not defined by stress data is formulated by the remaining compensation data generators, as per steps S50 through S56 and up to S56 correcting data based on preset stress-weighted sensing data. As depicted in corresponding figures, including FIG. 6 to FIG. 11, the driving method of the organic light-emitting display device incorporating at least one embodiment of the invention further encompasses a deterioration compensation process. For instance, stage S20 refers to detecting at least one deterioration area, based upon stress data from each pixel. The data counting unit generates cumulative data (Adata) and the prediction unit produces estimates of each pixel's deterioration state expectancy based on it. The deterioration compensation unit's area detection unit examines stress data distribution along horizontal lines, triggering relevant compensations where maximum stress occurs, encouraging preventive measures in system design responsive to displays and restoring inherent discrepancies noted during manufacturing. Using correction factors merged with TRC input, the second compensation data generation unit acquiring distinct factors for non-deteriorated regions similarly influences the methods' breadth. Operational during mode thresholds and thresholds defined by conceptive stress differences, these synthesized routines centralize processed thresholds framed during systematic operation scenarios.

The advantages, features, and methods for achieving the present invention are detailed in the following preferred embodiments, which will be described in conjunction with the accompanying drawings. Throughout the specification, the embodiments of the present invention disclose only transistors constituting pixels implemented in P-type, though FIG. 1 illustrates an organic light-emitting display device according to an embodiment of the invention. Referring to FIG. 1, the organic light-emitting display device of this embodiment comprises a display panel (10) in which pixels (PXL) are formed. A plurality of pixels (P) are arranged in a matrix form on the timing display panel (10). Each pixel (P) includes a semiconductor layer of transistors constituting the pixel made of oxide semiconductor, amorphous silicon (a-Si), multi-timing controller (11), vertical sync signal (Vsync), horizontal sync signal (Hsync), and dot clock signal (DCLK), and the data driving part (12), based on the data control signal (DDC) from the timing controller (11) during sensing operation, generates a gate pulse based on the data enable sensing first gate driving part (13) from the gate control signal (GDC) from the timing controller (11). FIG. 2 illustrates the pixel structure and data driving part according to a first embodiment. As shown in FIGS. 1 and 2, pixels arranged in the nth pixel line (HLn) have a first data line (14A) and a first reference voltage line (14B). The data driving part (12) comprises a digital-to-analog converter (DAC), an analog-to-digital converter (ADC), an initialization switch (SW1), and a sample digital-to-analog converter (DAC) for generating sensing operation data voltage (Vdata) under the control of the timing controller (11). Initialization switch (SW1) responds to the initialization control signal (SPRE) and connects each pixel (P) through the reference voltage line (14B) and drives it, the OLED driving transistor (DT), the first to third transistors (T1~T3), and the storage capacitor (Cst) are connected between the first node (N1) and the second node (N2). The first transistor (T1) connects to the gate electrode for supplying the scan signal (SCAN), and the second transistor (T2) connects to the gate electrode for supplying the sensing signal (SEN), tied to the second node (N2), the third transistor (T3) connects to the gate electrode for supplying the black data control signal (BS), through the reference voltage (Vref) associated with the reference voltage line (14B) applied during the programming period OLED illuminates. Referring to FIG. 3, the driving period of the organic light-emitting display device according to the invention consists of the first and second non-display intervals (X1, X2) and the image display interval. The first non-display interval (X1) is defined as the period from after power-on (PON) to the elapse of several frames, and the second compensation period exists outside the display period (DF). The compensation period consists of the first and second non-display periods (X1, X2) or vertical blank. Compensation periods include the programming period (Tpg), sensing period (Tsen), and sampling period (Tsam). During the programming period (Tpg), to turn on the driving transistor (DT), in the sensing period (Tsen), due to the current (Ids) flowing through the driving transistor (DT), and in the sampling period (Tsam), the source voltage of the driving transistor (DT) stored in the sensing capacitor (Cx) is connected for a certain period. FIG. 5 illustrates the timing of gate signals for display driving according to the first embodiment shown in FIG. 2. Referring to FIGS. 2 and 5, the display period operation according to the first embodiment is explained. One frame starts from the first horizontal period (1st H) writing data to the first pixel line (HL1) to the nth pixel line (HLn) driving duration includes programming period, emission period, and black data display period. During the first horizontal period (1st H), pixels (P) arranged in the first pixel line (HL1) receive the first scan signal (SCAN1) and the first sensing signal. After the first horizontal period (1st H) ends, the first scan signal (SCAN1) and the first sensing signal (SEN1) reverse to gate-off voltage. During the second horizontal period (2nd H), pixels (P) in the second pixel line (HL2) driving transistor (DT) receives the second scan signal and follows that similarly for the k-th horizontal period (k-th H) with k-th scan signal (SCAN(k)), and during the k-th horizontal period (k-th H), the first sensing signal (SEN1) and the first black data control signal (BS1) are set to the gate-on voltage. Similarly, for the (k+1)th horizontal period ((k+1)th H), pixels (P) in the (k+1)th pixel line are programmed. In FIG. 7, the first graph (gr1) depicts luminance in relation to data voltage (Vdata) when the black data display period (Tbdi) is absent. The black data control unit (100) uses the relationship between the black data display period (Tbdi) and corresponding luminance as shown in FIG. 7. An example table [Table 1] shows the duty ratio setting by the black data control unit (100). Referring to [Table 1], the black data control unit (100) operation is as follows: it receives image data (DATA) pixel line by pixel line and calculates the average image data; FIG. 8 and FIG. 9 illustrate a second embodiment pixel with a first transistor (T1) connected to the first node (N1) and a second node (N2). The driving of the organic light-emitting display device according to the second embodiment follows similarly to the first embodiment with a programming period, emission period, and any professional in the field can make various changes and modifications within the scope of the present invention without departing from the spirit thereof as described above. 10: Display Panel; 11: Timing Controller; Figure 6 shows the emission period and black data display period of each pixel line in the display panel.

Hereinafter, with reference to the accompanying drawings, an embodiment according to the present invention will be described in detail. Figure 1 is a perspective view showing an organic light-emitting display device with a touch sensor according to the present invention. The organic light-emitting display device with a touch sensor as shown in Figure 1 includes multiple sub-pixels arranged in a matrix on a substrate (111) as shown in Figure 2, where an active area (AA) is provided on the substrate (111) to display images through unit pixels arranged in a matrix. Each unit pixel comprises red, green, and blue sub-pixels, as well as a pixel driving circuit that includes a driving thin-film transistor (130), as shown in Figure 3. The driving thin-film transistor (130) operates in response to a data signal supplied to its gate electrode and includes a semiconductor layer (134) disposed on a buffer layer (112) with a gate insulating layer (102) in between. The light-emitting element (120) includes an anode electrode (122), at least one light-emitting stack (124) formed on the anode electrode (122), and a cathode electrode (126) facing the anode electrode (122) with the light-emitting stack (124) in between, aligned with a low-voltage supply line. An encapsulation unit (140) prevents external moisture or oxygen from penetrating the light-emitting element (120), which is vulnerable to them. The first inorganic encapsulation layer (142) is formed on the substrate (111) where the cathode electrode (126) is provided. The second inorganic encapsulation layer (146) and the interposed organic encapsulation layer (144) act to minimize infiltration by external moisture or oxygen and alleviate stress among layers due to bending of the organic light-emitting display device, respectively. A touch sensing line (154) and a touch driving line (152) are disposed on the second inorganic encapsulation layer (146) of the encapsulation unit (140). The touch sensor-equipped organic light-emitting display device includes multiple sub-elements, including the light-emitting element (120), and the touch driving line (152) within the touch sensor comprises multiple first touch electrodes (152e), arranged in the first direction X (row) on the topmost second inorganic encapsulation layer (146) of the encapsulation unit (140). The first bridge (152b) is arranged to detour along the second touch electrodes (154e) and the second bridge (154b) to maintain the first and second touch electrodes (152e,154e) on the same plane as the second inorganic encapsulation layer (146). Specifically, first touch electrodes (152e) arranged in the second row (H2), as depicted in Figure 4, extend electrically between the third row (H3) and the n-th row. The touch sensing line (154) includes multiple second touch electrodes (154e), interconnected electrically among them and to the same plane as the first touch electrodes (152e) and first bridge (152b) on the second inorganic encapsulation layer (146). In this way, the invention maintains the first and second touch electrodes (152e,154e) and the first and second bridges (152b,154b) on the same plane as the second inorganic encapsulation layer. The non-active area (NA) connects signal lines for driving the thin-film transistor (130) and the light-emitting element (120) with display pads (DP). The touch pad (170) and display pad (180) are each arranged between the substrate (111) and the encapsulation unit (144) with a buffer layer (112), interlayer insulating layer, connecting the touch pad (170) encompassing the first and second touch electrodes (152e,154e), the first and second bridges (152b,154b), and routing lines (160). The touch pad (170) establishes electrical connections via lower connection electrodes (182) and first and second upper connection electrodes (172,174) through the encapsulation unit (140). The lower connection electrode (182) is patterned similarly to the gate insulating layer (102) and disposed thereon. The first upper connection electrode (172) electrically connects the lower connection electrode (182) and the routing line (160), while the second upper connection electrode (174) connects the lower connection electrode (182) and the touch pad (170). Thus, the touch pad (170) and display pad (180) located in the non-active area (NA) allow the substrate (111) to be bent or folded. The bending area (BA), depicted in Figure 2, includes connection electrodes linking the routing line (160) and touch pad (170) with a crack prevention layer (188), made of an organic insulating material with greater deformability and impact resistance than inorganic insulators. Accordingly, the first and second touch electrodes (152e,154e), and first and second bridges (152b,154b) are maintained on the same plane. Figure 5 illustrates the cross-section of an organic light-emitting display device equipped with a touch sensor according to a second embodiment of the invention, similar to the device shown in Figure 3, with first and second touch electrodes (152e,154e) formed from a conductive mesh layer (163) without a transparent conductive film (161). The transparent conductive film (161) consists of highly transparent conductive materials such as ITO, IZO, IGZO, or AgNW, while the opaque conductive mesh (163) consists of highly conductive metals such as Ti, Al, Mo, MoTi, Cu, and Ta. Figure 6 exemplifies the mesh structure with consistent density for the opaque conductive film (163) of the touch electrodes (152e,154e). The second embodiment ensures first and second touch electrodes (152e,154e) are formed in the mesh pattern. Figure 8 shows the cross-section for a third embodiment, illustrating an organic light-emitting display device equipped with a touch sensor, compared with the device shown in Figure 3, featuring a color filter array on the second inorganic encapsulation layer (146) of the encapsulation unit (140), including color filters (192) and a black matrix (194) distinguishing each sub-pixel area. The color flattening layer (196), consisting of organic insulating material, overlays the color filter (192) and black matrix (194) on the substrate (111). In the depicted example, touch electrodes (152e,154e) are positioned above the color filter (192), however alternatives are discussed. Figure 10 demonstrates the cross-section of a fourth embodiment displaying the touch sensor-equipped organic light-emitting device featuring additional side protection films (148) to safeguard the exposed sides of the routing lines (160) and touch pads (170), especially where the second upper connection electrode (174) links through the pad contact hole (176) amid crack prevention layers (188). Thus, this fourth embodiment retains first and second touch electrodes (152e,154e) and bridge structures on the same plane. Figure 11 illustrates the application of such a device to large-area production, with Figures 12a and 13 emphasizing the consistent layout for bridge structures (152b,154b) across several electrodes. The manufacturing process explained in the flowchart includes forming the driving transistor (130), lower connection electrodes (182), and upper connection electrodes on the substrate (111) through multiple mask processes, followed by depositing a transparent conductive layer across the encapsulated substrate (140) and performing photolithography and etching for shaping. Figures 5, 6, and others describe additional configurations for electrodes (152e,154e, 152b, 154b) and routing, ensuring consistency post-encapsulation. This disclosure provides examples for illustrative purposes and should not limit the broader technical scope of the invention within the industry. Numerical indicators such as 142,146 reference inorganic encapsulation layers, while 144 references the organic encapsulation layer; Figure 3 illustrates a cross-section along line "????" in Figure 2, depicting the touch sensor-equipped organic light-emitting display device.

The aforementioned objectives, features, and advantages are described in detail with reference to the attached drawings, which include FIG. 4, illustrating the configuration of a compensation data generation apparatus for a display panel according to one embodiment of the present invention. Referring to FIG. 4, the compensation data generation apparatus (400) for a display panel in accordance with an embodiment of the present invention includes a reference XYZ data acquisition unit (42) that acquires reference XYZ data for a reference point of the display panel on which one or more pattern images are outputted. The pixel-by-pixel XYZ data acquisition unit (44) captures the front of the display panel where one or more pattern images are output, and according to an embodiment of the present invention, obtains an image from the camera (404). In this embodiment, the pixel-by-pixel XYZ data acquisition unit (44) can perform preprocessing on the detected panel image, using a first conversion matrix to convert pixel-specific camera RGB data to pixel-specific XYZ data. Additionally, noise contained within the panel image can be removed by the pixel-by-pixel XYZ data acquisition unit (44). Referring again to FIG. 4, the pixel-by-pixel XYZ data correction unit (46) corrects the XYZ data for each pixel using the reference XYZ data. Furthermore, the compensation data generation unit (48) combines the corrected pixel-by-pixel XYZ data with predetermined panel XYZ data. In another embodiment of the present invention, the compensation data generation unit (48) uses a second conversion matrix to convert panel XYZ data to panel RGB data. The process for generating compensation data by the compensation data generation apparatus (400), according to an embodiment of the present invention, includes obtaining reference XYZ data at a reference point of the display panel with one or more pattern images outputted. As an additional reference, one or more pattern images can be output across the display panel. The pixel-by-pixel XYZ data acquisition unit (44) detects the panel image from the front image of the display panel captured by the camera (404), on which one or more pattern images are outputted, applying preprocessing, such as a Median filter or Non-local Mean filter. Complementarily, panel images obtained from the front image captured by the camera (404) exhibit characteristic vignetting issues, addressed by considering vignetting components in the conversion to pixel-specific XYZ data. Once preprocessing is done, the pixel-by-pixel XYZ data acquisition unit (44) converts the acquired pixel-specific camera RGB data to pixel-specific XYZ data through specified mathematical formulae, where RC, GC, BC represent pixel-specific camera RGB data, and XC, YC, ZC signify pixel-specific XYZ data. The utilized first conversion matrix (M1) is established by capturing specific sample areas as illustrated in FIGS. 7 and 8, reducing the size progressively to optimize the conversion. In this iterative process, the size of the sample area diminishes thus including more precise samples. The pixel-by-pixel XYZ data acquisition unit (44) adapts the first conversion matrix (M1) to convert pixel-specific camera RGB data. FIG. 9 exemplifies this process where the pixel-specific camera RGB data is converted to pixel-specific XYZ data, which can be precalibrated against set RGB regions. Subsequently, the pixel-by-pixel XYZ data correction unit (46) adjusts each pixel's XYZ data based on reference points. The compensation data generation unit (48) then combines this with predetermined panel XYZ data for RGB compensation. Within an embodiment of the present invention, compensation data generation involves using a second conversion matrix (M2) to convert each pixel's panel XYZ data to panel RGB data, tested and determined through real-world panel measurements. The inventive approach comprehensively utilizes reference points for data (i.e., reference XYZ data) to enhance the uniformity across the panel's rendering. FIG. 10 presents an example application of generated compensation data to adjust input RGB data using gamma transformation sections (1002) within the display panel. An additional position determination unit (1110) identifies the corresponding panel pixel location from input RGB data, facilitating compensation data conversion performed by a data conversion unit (1006). FIG. 11 presents a flowchart of the compensation data generation method according to an embodiment of the invention, emphasizing sequential pattern image output capturing and processing through pixel-specific transformations and corrections using established matrices and reference XYZ parameters. Lastly, employing the compensation data as demonstrated in FIG. 12, results in streamlined chromatic consistency across disparate pixel locations, resolving to optimized pixel-specific compensation. Finally, FIG. 4 herein depicts the schematic configuration of the display panel compensation data generation apparatus in accordance with one of the present invention's embodiments.

The central server (100) is a remote server connected to the data collection unit (200) via a communication line. The central server (100), along with the data collection unit (200), may be integrated into or configured independently of the display device (300). The data collection unit (200) gathers panel information from the memory (16) of the display device (300) and uploads it to the central server (100); the display device (300) can be implemented as an organic light-emitting display, but this is not a limitation. The technical concept of the present invention allows for an organic display device (300) that may include the memory (16), a compensation unit (17), and a degradation information extraction unit (18), but this is not restrictive. In an embodiment of this invention's degradation compensation system for a display device, panel identification information and degradation -7- data reference 2 concerning the display device (300) involve memory (16), compensation unit (17), and degradation information extraction display panel (10) where multiple data lines (14) and gate lines (15) intersect and pixels (PXL) appear in a matrix; referring to diagram 4, switch TFT (ST) is turned on/off according to the gate signal (SCAN) between the data line (14) and first node (N1); moreover, referring to diagram 2, the panel driving units (12, 13) write input video data (DATA) to the pixels (PXL) of the display panel (10). Diagram 2 also shows the source driver (12) receiving corrective video data per frame from the timing controller (11). The compensation operation of the present invention, based on data counting techniques, extracts OLED degradation information, affecting each pixel (PXL). A multiplexer (not shown) may also be arranged between the data lines (14) of the source driver (12) and display panel (10). The timing controller (11) provides input video data (DATA) to the compensation unit (17) and receives corrected image data timing control signals (DDC) driven by source start pulse and source sampling clock signals. As shown in diagram 5, the data collection unit (200) may be implemented with analysis software utilized by A/S (After Service) personnel. Additionally, diagram 6 indicates that the data collection unit (200) may be implemented with an onboard OS (Operating System) within the display device (300). The central server (100) updates the relational expression based on collected degradation information using a process condition verification unit (100A) and database. The process condition verification unit (100A) determines under which conditions the panel information, identified by the panel ID received from data collection unit (200), is stored. Once the process conditions are verified, the database update unit (100B) inputs panel information from the data collection unit (200) to conduct regression analysis. Following updates of the degradation information pertinent to those process conditions, the regression analysis performance unit (100C) utilizes the resultant big data (graph information) to update the existing relation in the relation update unit (100D). The relation selection unit (100E) selects a relational expression matching the process conditions of the display panel (10). Using the selected relational expression, the compensation unit (17) conducts degradation compensation with the operational unit (171), compensation LUT (172), and data compensation. The operational unit (171) applies the accumulated stress value from memory (16) to the relational expression received from the central server (100), and the data compensation unit (173) multiplies the compensation gain to the input video data (DATA) to generate corrected video data (CDATA). 100: Central Server 200: Data Collection Unit Figure 1 illustrates the degradation compensation system for a display device according to an embodiment of the present invention.

A sensing transistor (ST) is configured with its gate electrode connected to the first B scan line (GL1b) and its first electrode connected to the first sensing line (VREF1), wherein the sensing and voltage charging unit (SEN & PRE) is capable of sensing the characteristics of elements contained in a sub-pixel via the first sensing line (VREF1). The sensing switch unit (SASW) has its gate electrode connected to the sensing initiation signal line (SIO) and its first electrode connected to the first sensing line (VREF1). The initialization voltage output switch unit (SPSW) is responsible for outputting the initialization voltage generated by the initialization voltage source (VPRES) to the first sensing line (VREF1). The driving voltage output switch unit (RPSW) outputs the driving voltage generated by the driving voltage source (VPRER) through the first sensing line (VREF1). Switch units for outputting initialization voltages from the first to the N-th (SPSW1 ~ SPSWn) are adapted to correspond to the first to N-th sensing lines (VREF1 ~ VREFn) respectively, and switch units for outputting driving voltages from the first to the N-th (RPSW1 ~ RPSWn) are adapted to correspond to the first to the N-th sensing lines (VREF1 ~ VREFn) respectively. Each sensing switch unit from the first to the N-th (SASW1 ~ SASWn) corresponds to the first through the N-th sensing lines (VREF1 ~ VREFn), and the first through N-th sensing and initialization voltage output switch units (SPSW) output the initialization voltage generated by the initialization voltage source (VPRES) to the first sensing line (VREF1). The driving voltage output switch unit (RPSW) outputs the driving voltage generated by the driving voltage source (VPRER) through the first sensing line (VREF1). The noise improvement switch unit (NPSW) outputs a variable voltage generated by the variable voltage source (VPREN) through the first sensing line (VREF1). Another embodiment indicates that the noise improvement switch unit (NPS) would only output if noise is detected on the first sensing line (VREF1). Figure 9 illustrates the sensing and voltage charging section of an organic light-emitting diode display device in accordance with an embodiment of the present invention.

An organic light-emitting display device according to an embodiment of the present invention includes a plurality of sub-pixels (SPX). Referring to FIG. 1 of the plurality of sub-pixels, each sub-pixel (SPX) includes a switching thin-film transistor (T1), a driving thin-film transistor (T2), a storage capacitor, and four thin-film transistors contained therein, each comprising an active layer, a gate electrode, a source electrode, and a drain electrode. The switching thin-film transistor (T1) has a drain electrode connected to a data line, a source electrode connected to a first node (N1), and a gate; the driving thin-film transistor (T2) has a drain electrode connected to a high-potential line (i.e., Vdd line) and an anode of an organic light-emitting device (OLED). The storage capacitor (Cst) is connected to one electrode and to the source electrode of the driving thin-film transistor (T2). The sensing thin-film transistor (T3) has a drain electrode connected to the source electrode of the driving thin-film transistor (T2) and is connected to a reference line. The auxiliary thin-film transistor (T4) has a drain electrode electrically connected to the cathode of the organic light-emitting device (OLED) and the reference line. FIG. 2 presents a schematic plan view of the sub-pixel in FIG. 1. FIG. 3 shows a schematic cross-sectional view for the IIIa-IIIa' and IIIb-IIIb' sections of FIG. 2. The Vdd line (VDL) is electrically connected to the driving thin-film transistor (T2), and the reference line (RL), electrically connected to the sensing thin-film transistor (T3) and the auxiliary thin-film transistor (T4), for example, is used for sensing the threshold voltage of the driving thin-film transistor (T2) during the sensing time, while during emission time, the reference line (RL) delivers the Vss voltage to the auxiliary thin-film transistor (T4). The sensing gate line (SGL) is electrically connected to the gate electrode of the sensing thin-film transistor (T3), and referring to FIG. 3, the driving thin-film transistor (T2) and the auxiliary thin-film transistor (T4) are disposed on the substrate (110). Specifically, on the substrate (110), a buffer layer (381) is disposed, and the active layer of the driving thin-film transistor (T2) is on the buffer layer (381). On the active layer (331) of the driving thin-film transistor (T2) and the active layer (341) of the auxiliary thin-film transistor (T4), a first gate insulation layer is disposed, as shown in FIG. 3. A planarization layer (384) is disposed to cover the driving thin-film transistor (T2) and the auxiliary thin-film transistor (T4). The anode (351) of the organic light-emitting device (OLED) is arranged on the planarization layer (384), and through the contact hole of the planarization layer (384), the driving thin-film transistor is arranged in such a way that a bank layer (385) is provided to surround the periphery of the anode (351). The bank layer (385) defines the emission area of each sub-pixel (SPX), and an organic emission layer (352) is disposed on the anode (351) and the bank layer (385). The organic emission layer (352) constitutes part of the plurality of sub-pixels (SPX). The organic light-emitting display device according to an exemplary embodiment of the present invention further includes a compensation component storing the threshold voltage of the driving thin-film transistor (T2), connected electrically to the cathode (353) of the organic light-emitting device (OLED) and the reference line. Meanwhile, as shown in FIG. 4, during the emission period (te), a high level (H) auxiliary gate voltage (Vag) is applied to the auxiliary gate. FIG. 6 describes the effect of reducing the Vss rising phenomenon in the organic light-emitting display device according to an embodiment of the present invention. Referring to FIG. 7, the sensing thin-film transistor (T3) and the auxiliary thin-film transistor (T4) are different types of thin-film transistors; the gate electrode of the sensing thin-film transistor (T3) and the gate electrode of the auxiliary thin-film transistor (T4) are electrically connected to each other. FIG. 8 shows a schematic plan view of the sub-pixel in FIG. 7. FIG. 9 shows a schematic cross-sectional view for the IXa-IXa' and IXb-IXb' sections of FIG. 8. Referring to FIG. 8, the gate electrode of the sensing thin-film transistor (T3) and the gate electrode of the auxiliary thin-film transistor (T4) are commonly connected. The source electrode of the sensing thin-film transistor (T3) and the drain electrode of the auxiliary thin-film transistor (T4) are electrically connected to the reference line (RL). Referring to FIG. 9, the sensing thin-film transistor (T3) and the auxiliary thin-film transistor (T4) are arranged on different planes. The source electrode (943) and drain electrode (944) of the auxiliary thin-film transistor (T4) are disposed on the active layer (991) of the sensing thin-film transistor (T3). A second gate insulating layer (986) is disposed on the active layer (991) of the sensing thin-film transistor (T3), and referring to FIG. 11, the organic light-emitting display device (1100) comprises a plurality of sub-pixels (SPX) disposed on the substrate (110), wherein the data drive unit (1121) applies data voltage to each of the sub-pixels (SPX) via the data line. The gate drive unit (1122) applies gate voltage to each of the sub-pixels (SPX) via the gate line. For example, referring to FIG. 12, the first sub-pixel (SPX1) includes an island auxiliary electrode (1260) electrically separated from the anode (1251). Meanwhile, the island auxiliary electrode (1260) of the first sub-pixel (SPX1) is connected at the contact area (CA) with the cathode of the first sub-pixel (SPX1). Referring to FIG. 13, the sensing thin-film transistor (T3) and the auxiliary thin-film transistor (T4) are of different types of thin-film transistors. Additionally, the sensing thin-film transistor (T3) is electrically connected to the reference line, and the auxiliary thin-film transistor (T4) is connected to the lower auxiliary wiring. The reference line (RL) is electrically connected to the source electrode of the sensing thin-film transistor (T3). For instance, the drain electrode of the sensing thin-film transistor (T3) is connected to the source electrode of the driving thin-film transistor (T2) and the anode of the organic light-emitting device. As depicted in FIGs. 14 and 15, the voltage applied to the reference line (RL) is used to address the sensing thin-film transistor (T3). Another embodiment of the organic light-emitting display device includes the cathode (1253) of the organic light-emitting device (OLED) electrically connected, and this variant also includes an additional lower auxiliary wiring (VSL) for transmitting the Vss voltage. In the case of a normal organic light-emitting device (OLED), the cathode sensing current (Ids) that enters the anode traverses the organic emission layer to the cathode; however, when the organic light-emitting device (OLED) deteriorates and a fault occurs, a leakage current may arise between the anode and the cathode. As previously described, in the event of a fault in the organic light-emitting device (OLED), leakage current occurs between the anode and the cathode when such a condition arises. SPX: Sub-pixel FIG. 1 illustrates a circuit diagram for explaining a sub-pixel arranged in the organic light-emitting display device according to an embodiment of the present invention. [0034]
