[0027] In the following, various embodiments of this disclosure will be described in detail with reference to the accompanying drawings.

[0028] Figure 1 This is a diagram that schematically illustrates the configuration of a touch display device 100 according to an embodiment of the present disclosure. Figure 2 This is a diagram illustrating an example of the circuit structure of a sub-pixel SP included in a touch display device 100 according to an embodiment of the present disclosure.

[0029] Reference Figure 1 The touch display device 100 may include a display panel 110 and a gating drive circuit 120, a data drive circuit 130, and a controller 140 for driving the display panel 110. In addition to the configuration for display driving, the touch display device 100 may also include a configuration for touch sensing.

[0030] The display panel 110 may include a display area AA with multiple sub-pixels SP and a non-display area located outside the display area AA. Multiple gate lines GL and multiple data lines DL may be arranged on the display panel 110. The multiple sub-pixels SP may be located in the area where the gate lines GL and data lines DL intersect.

[0031] The gating drive circuit 120 can be controlled by the controller 140. The gating drive circuit 120 can sequentially output scanning signals to multiple gating lines GL arranged on the display panel 110, thereby controlling the driving timing of multiple sub-pixels SP.

[0032] The gating drive circuit 120 may include one or more gating driver integrated circuits (GDICs). Depending on the driving method, the gating drive circuit 120 may be located only on one side of the display panel 110, or it may be located on both sides of it.

[0033] Each gating driver integrated circuit (GDIC) can be connected to the bonding pads of the display panel 110 via a tape-on-board (TAB) method or a chip-on-glass (COG) method. Alternatively, each gating driver integrated circuit (GDIC) can be implemented using an in-panel gating (GIP) method and then directly disposed on the display panel 110. Alternatively, the gating driver integrated circuit (GDIC) can be integrated and disposed on the display panel 110. Alternatively, each gating driver integrated circuit (GDIC) can be implemented using a chip-on-film (COF) method, where components are mounted on a film connected to the display panel 110.

[0034] The data driving circuit 130 can receive image data DATA from the controller 140 and convert the image data DATA into an analog data voltage Vdata. The data driving circuit 130 can output the data voltage Vdata to each data line DL according to the timing of the scan signal applied through the gate line GL, so that each of the multiple sub-pixels SP emits light with a brightness according to the image data.

[0035] The data driver circuit 130 may include one or more source driver integrated circuits (SDICs). Each source driver integrated circuit (SDIC) may include a shift register, latch circuit, digital-to-analog converter, output buffer, etc.

[0036] Each source driver integrated circuit (SDIC) can be connected to the bonding pads of the display panel 110 via the tape auto-bonding (TAB) method or the chip-on-glass (COG) method. Alternatively, each source driver integrated circuit (SDIC) can be directly disposed on the display panel 110. Alternatively, the source driver integrated circuit (SDIC) can be integrated and arranged on the display panel 110. Alternatively, each source driver integrated circuit (SDIC) can be implemented using the chip-on-film (COF) method. In this case, each source driver integrated circuit (SDIC) can be mounted on a film connected to the display panel 110 and can be electrically connected to the display panel 110 via leads on the film.

[0037] The controller 140 can supply various control signals to the gating drive circuit 120 and the data drive circuit 130, and control the operation of the gating drive circuit 120 and the data drive circuit 130.

[0038] The controller 140 can be mounted on a printed circuit board, flexible printed circuit, etc. The controller 140 can be electrically connected to the gating drive circuit 120 and the data drive circuit 130 via the printed circuit board, flexible printed circuit, etc.

[0039] Controller 140 can enable the gating drive circuit 120 to output scan signals according to the timing implemented in each frame. Controller 140 can convert data signals received from an external source (e.g., a host system) to conform to the data signal format used in data drive circuit 130, and then output the converted image data DATA to data drive circuit 130.

[0040] The controller 140 can receive various timing signals, including vertical synchronization signal VSYNC, horizontal synchronization signal HSYNC, input data enable signal DE, clock signal CLK, etc., as well as image data from an external source (e.g., a host system).

[0041] The controller 140 can use various timing signals received from the outside to generate various control signals, and can output the control signals to the gating drive circuit 120 and the data drive circuit 130.

[0042] For example, in order to control the gating drive circuit 120, the controller 140 can output various gating control signals GCS, including gating start pulse GSP, gating shift clock GSC, gating output enable signal GOE, etc.

[0043] The strobe start pulse GSP controls the start timing of operation for one or more strobe driver integrated circuits (GDICs) constituting the strobe drive circuit 120. The strobe shift clock GSC, serving as a common input to one or more strobe driver integrated circuits (GDICs), controls the shift timing of the scan signal. The strobe output enable signal GOE specifies timing information for one or more strobe driver integrated circuits (GDICs).

[0044] In addition, in order to control the data drive circuit 130, the controller 140 can output various data control signals DCS, including the source start pulse SSP, the source sampling clock SSC, and the source output enable signal SOE.

[0045] The source start pulse SSP can control the data sampling start timing of one or more source driver integrated circuits (SDICs) constituting the data drive circuit 130. The source sampling clock SSC can be a clock signal used to control the timing of data sampling in each source driver integrated circuit (SDIC). The source output enable signal SOE can control the output timing of the data drive circuit 130.

[0046] The touch display device 100 may also include a power management integrated circuit for supplying various voltages or currents to the display panel 110, the gating drive circuit 120, the data drive circuit 130, etc., or controlling the supply of various voltages or currents to them.

[0047] Each sub-pixel SP is an area defined by the intersection of the gate line GL and the data line DL, and depending on the type of touch display device 100, a liquid crystal layer or a light-emitting element may be disposed on the sub-pixel SP.

[0048] For example, when the touch display device 100 is an organic light-emitting display device, organic light-emitting diodes (OLEDs) and various circuit elements can be disposed on multiple sub-pixels (SPs). By controlling the current supplied to the OLEDs disposed on the sub-pixels (SPs) through the various circuit elements, each sub-pixel (SP) can display a brightness corresponding to the image data.

[0049] Alternatively, in some cases, light-emitting diodes (LEDs), micro LEDs (μLEDs), or quantum dot LEDs can be disposed on sub-pixels (SPs).

[0050] Reference Figure 2 Each of the multiple sub-pixels SP may include a light-emitting element ED. The sub-pixel SP may include a drive transistor DRT that controls the drive current supplied to the light-emitting element ED.

[0051] The subpixel SP may include at least one circuit element other than the light-emitting element ED and the driving transistor DRT for driving the subpixel SP.

[0052] For example, a sub-pixel SP may include a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, and a storage capacitor Cstg.

[0053] Figure 2 The example shown represents a 6T1C structure with six transistors and one capacitor, but the embodiments disclosed herein are not limited thereto. Figure 2 The example shown represents the case where the transistors are P-type, but at least some of the transistors set on the sub-pixel SP can be N-type.

[0054] Furthermore, for example, the transistor disposed on the sub-pixel SP may include a semiconductor layer made of low-temperature polycrystalline silicon (LTPS) or a semiconductor layer made of oxide semiconductor. Additionally, in some cases, transistors including a semiconductor layer made of LTPS and transistors including a semiconductor layer made of oxide semiconductor may be disposed together on the sub-pixel SP.

[0055] The first transistor T1 can be electrically connected between the data line DL and the first node N1. The first transistor T1 can be controlled by the first scan signal Scan1 supplied through the first gate line GL1. The first transistor T1 can control the data voltage Vdata to be applied to the first node N1.

[0056] The second transistor T2 can be electrically connected between the second node N2 and the third node N3. The second node N2 can be the gate node of the driving transistor DRT. The third node N3 can be the drain node or the source node of the driving transistor DRT. The second transistor T2 can be controlled by the second scan signal Scan2 supplied through the second gate line GL2. The second transistor T2 can perform the operation of compensating for changes in the threshold voltage of the driving transistor DRT.

[0057] The third transistor T3 can be electrically connected between the line supplying the reference voltage Vref and the first node N1. The third transistor T3 can be controlled by the light emission control signal EM supplied through the light emission control line EML. The third transistor T3 can control whether the first node N1 is discharged or whether the reference voltage Vref is applied to the first node N1.

[0058] The fourth transistor T4 can be electrically connected between the third node N3 and the fifth node N5. The fifth node N5 can be electrically connected to the light-emitting element ED. The fourth transistor T4 can be controlled by the light-emitting control signal EM supplied through the light-emitting control line EML. The fourth transistor T4 can control the timing of the drive current being supplied to the light-emitting element ED.

[0059] The fifth transistor T5 can be electrically connected between the line supplying the reference voltage Vref and the fifth node N5. The fifth transistor T5 can be controlled by the second scan signal Scan2 supplied through the second gate line GL2. The fifth transistor T5 can control whether the fifth node N5 is discharged or whether the reference voltage Vref is applied to the fifth node N5.

[0060] The driving transistor DRT can be electrically connected between the fourth node N4 and the third node N3. The fourth node N4 can be electrically connected to the line supplying the first driving voltage VDD. For example, the first driving voltage VDD can be a high-level driving voltage. The fourth node N4 can be the source node or the drain node of the driving transistor DRT.

[0061] The driving transistor DRT can be controlled by the difference between the voltage at the second node N2 and the voltage at the fourth node N4. The driving transistor DRT can control the driving current supplied to the light-emitting element ED.

[0062] The driving transistor DRT may include a back gate electrode electrically connected to a fourth node N4. The current output of the driving transistor DRT can be stably executed via the back gate electrode electrically connected to the source node of the driving transistor DRT. For example, the back gate electrode can be configured using a metal layer to block external light from entering the channel of the driving transistor DRT.

[0063] The light-emitting element ED can be electrically connected between the fifth node N5 and the line supplying the second driving voltage VSS. For example, the second driving voltage VSS can be a low-potential driving voltage.

[0064] The light-emitting element ED has a first electrode E1 electrically connected to the fifth node N5, a second electrode E2 to which a second driving voltage VSS is applied, and a light-emitting layer EL disposed between the first electrode E1 and the second electrode E2.

[0065] The light-emitting element (ED) can display brightness based on the driving current supplied by the driving transistor DRT. The driving timing of the ED can be controlled by the fourth transistor T4.

[0066] Brief description Figure 2 The driving timing of the sub-pixel SP shown can be supplied with a second scan signal Scan2 with a conduction level via the second gate line GL2. When the transistor on the sub-pixel SP is P-type, the conduction level can be low.

[0067] The second transistor T2 and the fifth transistor T5 can be turned on by the second scan signal Scan2, which has a conduction level.

[0068] When the second transistor T2 is turned on, the second node N2 and the third node N3 can be electrically connected. The threshold voltage of the driving transistor DRT, reflected in the first driving voltage VDD, can be applied to the second node N2 through the second transistor T2. This process can compensate for changes in the threshold voltage of the driving transistor DRT.

[0069] When the fifth transistor T5 is turned on, the reference voltage Vref can be applied to the fifth node N5. The fifth node N5 can then be initialized.

[0070] Subsequently, the first scan signal Scan1 with a conduction level can be supplied through the first strobe line GL1.

[0071] The first transistor T1 can be turned on by the first scan signal Scan1, which has a conduction level.

[0072] When the first transistor T1 is turned on, the data voltage Vdata can be applied to the first node N1.

[0073] It can be transformed into a state where a first drive voltage VDD, reflecting the threshold voltage of the drive transistor DRT, and a data voltage Vdata are applied across the storage capacitor Cst.

[0074] Subsequently, the light control signal EM can be supplied through the light control line EML.

[0075] The third transistor T3 and the fourth transistor T4 can be turned on.

[0076] When the third transistor T3 is turned on, the voltage of the first node N1 can be changed to the reference voltage Vref. The voltage of the second node N2, which is connected to the first node N1, can be changed according to the change in the voltage of the first node N1.

[0077] The state can be changed to a state where the threshold voltage of the driving transistor DRT and the data voltage Vdata are reflected in the voltage of the first driving voltage VDD applied to the second node N2, and the state can be changed to a state where the first driving voltage VDD is applied to the fourth node N4. The difference between the voltage of the second node N2 and the voltage of the fourth node N4 can be a voltage reflecting the data voltage Vdata and the threshold voltage of the driving transistor DRT. The driving current corresponding to the data voltage Vdata can be supplied by the driving transistor DRT.

[0078] When the fourth transistor T4 is turned on, the drive current supplied by the driving transistor DRT can be supplied to the light-emitting element ED.

[0079] The light-emitting element (ED) can display brightness according to the driving current, and the sub-pixels (SP) including the ED can display an image corresponding to the image data.

[0080] Furthermore, embodiments of this disclosure can provide the function of sensing user touches on the display panel 110 by implementing a touch sensor structure on the display panel 110 that displays images.

[0081] Figures 3 to 5 This is a diagram illustrating an example of a touch sensor structure included in a touch display device 100 according to an embodiment of the present disclosure.

[0082] Reference Figure 3 The touch display device 100 may include multiple touch electrode lines TEL and multiple touch wiring lines TL disposed in the display panel 110. The touch display device 100 may include a touch driving circuit 150 for driving the multiple touch electrode lines TEL and multiple touch wiring lines TL.

[0083] Each of the multiple touch electrode lines TEL can be electrically connected to the touch driver circuit 150 via touch wiring TL. The touch driver circuit 150 can be configured separately, or in some cases, it can be integrated with circuitry used for display driving. For example, the touch driver circuit 150 can be configured to be integrated with the data driver circuit 130.

[0084] Each of the multiple touch electrode lines TEL may include multiple touch electrodes TE electrically connected to each other along one direction. Furthermore, each of the multiple touch electrode lines TEL may include multiple touch electrode connection patterns CL that electrically connect the multiple touch electrodes TE to each other.

[0085] For example, each of the multiple X-TEL lines may include multiple X-TELs arranged in a first direction and multiple X-TEL connection patterns X-CL that electrically connect the multiple X-TELs to each other.

[0086] Each of the multiple Y-touch electrode lines Y-TEL may include multiple Y-touch electrodes Y-TE arranged in a second direction intersecting the first direction, and multiple Y-touch electrode connection patterns Y-CL electrically connecting the multiple Y-touch electrodes Y-TE to each other.

[0087] The X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL can be disposed on different layers. Alternatively, the X-touch electrode X-TE and the Y-touch electrode Y-TE can be disposed on the same layer. In this case, one of the X-touch electrode connection pattern X-CL and the Y-touch electrode connection pattern Y-CL can be disposed on a different layer than the touch electrode TE.

[0088] For example, the touch electrode TE can be quadrilateral in shape, but is not limited to this.

[0089] The touch electrode TE can be made of a transparent conductive material and can be set without interrupting the image display function of the display panel 110.

[0090] Alternatively, the touch electrode TE can be made of an opaque metal. In this case, the touch electrode TE can be in a shape that is open to the area corresponding to the light-emitting area of ​​the light-emitting element ED disposed in the display panel 110. For example, the touch electrode TE is implemented as a mesh and disposed away from the light-emitting area.

[0091] In a structure in which multiple X-touch electrode lines X-TEL and multiple Y-touch electrode lines Y-TEL are arranged to intersect each other, the touch driving circuit 150 can drive the touch electrode lines TEL and perform touch sensing through the touch wiring TL.

[0092] For example, one of the X-TEL touch electrode line and the Y-TEL touch electrode line can be a touch driving electrode that applies a touch driving signal. The other of the X-TEL touch electrode line and the Y-TEL touch electrode line can be a touch sensing electrode that detects a touch sensing signal.

[0093] When different signals are applied to the X touch electrode line X-TEL and the Y touch electrode line Y-TEL, the touch driving circuit 150 can detect the change in mutual capacitance generated when the user touches the screen.

[0094] The touch driving circuit 150 can send sensing data to the touch controller based on the detected changes in mutual capacitance. The touch controller can detect whether a touch has occurred and the touch coordinates on the display panel 110 based on the sensing data received from the touch driving circuit 150.

[0095] The touch electrode line TEL set in the display panel 110 can be set to be divided into multiple areas in the display area AA.

[0096] When the touch electrode lines (TELs) are divided into different areas, the load on the touch electrode lines (TELs) can be reduced. As the area of ​​the display panel 110 increases, the load on the touch electrode lines (TELs) can be reduced, and the performance of touch sensing can be improved.

[0097] Reference Figure 4 The display area AA of the display panel 110 may include multiple sub-areas SAA divided by the boundary of the first direction and the boundary of the second direction.

[0098] The display area AA may include at least two or more sub-areas SAA divided along a first boundary BL1 according to a first direction. The display area AA may include at least two or more sub-areas SAA divided along a second boundary BL2 according to a second direction.

[0099] For example, the first sub-region SAA1 and the second sub-region SAA2 can be divided by the first boundary BL1. The third sub-region SAA3 and the fourth sub-region SAA can also be divided by the first boundary BL1.

[0100] The first subregion SAA1 and the third subregion SAA3 can be separated by the second boundary BL2. The second subregion SAA2 and the fourth subregion SAA4 can also be separated by the second boundary BL2.

[0101] Figure 4 An example is shown where the display area AA is divided into four sub-areas SAA, but the display area AA can be divided into multiple sub-areas SAA by the first boundary BL1 and the second boundary BL2.

[0102] The touch electrode line TEL set on each of the multiple sub-regions SAA can be set to be separate from the touch electrode line TEL set on different sub-regions SAA.

[0103] The touch electrode line TEL, located on each of the multiple sub-regions SAA, can be driven independently.

[0104] For example, the first X touch electrode line X-TEL-a disposed on the first sub-region SAA1 can be electrically connected to the first touch driving circuit 151 via the first X touch wiring X-TL-1. The first Y touch electrode line Y-TEL-1 can be electrically connected to the first touch driving circuit 151 via the first Y touch wiring Y-TL-1.

[0105] The second X-touch electrode line X-TEL-2, located on the second sub-region SAA2, can be electrically connected to the second touch driver circuit 152 via the second X-touch wiring X-TL-2. The second Y-touch electrode line Y-TEL-2 can be electrically connected to the second touch driver circuit 152 via the second Y-touch wiring Y-TL-2.

[0106] The first X-touch electrode line X-TEL-1 and the first Y-touch electrode line Y-TEL-1 can be driven by the first touch driving circuit 151. The second X-touch electrode line X-TEL-2 and the second Y-touch electrode line Y-TEL-2 can be driven by the second touch driving circuit 152. The touch electrode lines TEL of the third sub-region SAA3 and the fourth sub-region SAA4 can be configured with a similar structure to the touch electrode lines TEL of the first sub-region SAA1 and the second sub-region SAA2, and can be driven in a similar manner.

[0107] The touch electrode line TEL located on the first sub-region SAA1 and the touch electrode line TEL located on the second sub-region SAA2 are electrically separated and driven by different touch driving circuits 150, which can reduce the load on touch sensing and improve the performance of touch sensing.

[0108] Furthermore, in some cases, the touch electrode lines (TELs) disposed on two or more sub-regions (SAA) can be driven by the same touch driving circuit 150. For example, the touch electrode lines (TELs) disposed on the first sub-region (SAA1) and the touch electrode lines (TELs) disposed on the second sub-region (SAA2) can be driven by the same touch driving circuit 150. The touch electrode lines (TELs) disposed on the third sub-region (SAA3) and the fourth sub-region (SAA4) can be driven by the same touch driving circuit 150. Alternatively, for another example, the touch electrode lines (TELs) disposed on the first sub-region (SAA1), the second sub-region (SAA2), the third sub-region (SAA3), and the fourth sub-region (SAA4) can be driven by the same touch driving circuit 150. In this case, when the touch electrode lines (TELs) disposed on each sub-region (SAA) are configured as separate structures, the load on the touch electrode lines (TELs) can be reduced, and the touch sensing performance can be improved.

[0109] As described above, in a structure where touch electrode lines TEL are separately set on each of multiple sub-regions SAA, some touch wiring TL can be set on the display area AA.

[0110] For example, the first X-touch wiring X-TL-1, which is electrically connected to the first X-touch electrode line X-TEL-1 of the first sub-region SAA1, and the second X-touch wiring X-TL-2, which is electrically connected to the second X-touch electrode line X-TEL-2 of the second sub-region SAA2, can be set on the non-display area NA.

[0111] The second Y-touch wiring Y-TL-2, which is electrically connected to the second Y-touch electrode line Y-TEL-2 of the second sub-region SAA2, can be set on the non-display area NA.

[0112] A portion of the first Y-touch wiring Y-TL-1, which is electrically connected to the first Y-touch electrode line Y-TEL-1 of the first sub-region SAA1, can be set on the display area AA.

[0113] This portion of the first Y-touch wiring Y-TL-1 can be located on the second sub-region SAA2. The first Y-touch wiring Y-TL-1 can pass through the second sub-region SAA2 and can be electrically connected to the first Y-touch electrode line Y-TEL-1 located on the first sub-region SAA1.

[0114] When a portion of the first Y-touch wiring Y-TL-1 is disposed on the second sub-region SAA2, at least one of the second X-touch electrode line X-TEL-2 or the second Y-touch electrode line Y-TEL-2 disposed on the second sub-region SAA2 can be configured to be separated on the region where the first Y-touch wiring Y-TL-1 is disposed. Figure 4 An example is shown where, due to the arrangement of the first Y-touch wiring Y-TL-1, the second Y-touch electrode line Y-TEL-2 is configured to be divided on the second sub-region SAA2.

[0115] As described above, when the touch electrode line TEL is configured to be divided into various sub-regions SAA, the number of touch wiring TLs connected to the touch electrode line TEL can be increased. When the number of touch wiring TLs increases, the non-display area NA can increase due to the arrangement of the touch wiring TLs. However, when the first Y touch wiring Y-TL-1 is electrically connected to the first Y touch electrode line Y-TEL-1 of the first sub-region SAA1 through the display area AA, it may not be necessary to add a separate area on the non-display area NA for arranging the first Y touch wiring Y-TL-1. The non-display area NA can be divided into sub-regions SAA without increasing due to the addition of the first Y touch wiring Y-TL-1.

[0116] The touch sensor structure, divided into multiple sub-regions (SAA), can be divided into an upper touch sensor portion and a lower touch sensor portion based on a first boundary (BL1). Furthermore, the touch sensor structure can be divided into a left touch sensor portion and a right touch sensor portion based on a second boundary (BL2). Here, compared to the upper touch sensor portion, the lower touch sensor portion can be positioned closer to the pads where the touch wiring (TL) connections are located. That is, the distance between the lower touch sensor portion and the area where the touch wiring (TL) connections are located can be smaller than the distance between the upper touch sensor portion and the area where the pads are located.

[0117] Furthermore, when the area of ​​the second Y-touch electrode line Y-TEL-2 is reduced due to the first Y-touch wiring Y-TL-1, the difference in touch sensing sensitivity can be prevented by making the area of ​​the first Y-touch electrode line Y-TEL-1 the same as or similar to the area of ​​the second Y-touch electrode line Y-TEL-2.

[0118] Reference Figure 5 At least one first dummy electrode DME1, which is separate from the first Y-touch electrode line Y-TEL-1, can be disposed on at least a portion of the area of ​​the first sub-region SAA1 corresponding to the area of ​​the second sub-region SAA2 where the first Y-touch wiring Y-TL-1 is disposed.

[0119] The first dummy electrode DME1 can be electrically disconnected from the first Y-touch electrode line Y-TEL-1.

[0120] The width of the region where the first dummy electrode DME1 is located can be the same as or similar to the width of the first Y-touch wiring Y-TL-1. Alternatively, the width of the region where the first dummy electrode DME1 is located can be the same as or similar to the width of the region on the second sub-region SAA2 where the second Y-touch electrode line Y-TEL-2 is not located. Furthermore, the space between the two portions of the first Y-touch electrode line Y-TEL-1 located on both sides of the first dummy electrode DME1 can be the same as or similar to the space between the two portions of the second Y-touch electrode line Y-TEL-2 located on both sides of the first Y-touch wiring Y-TL-1.

[0121] The area of ​​the first Y-touch electrode line Y-TEL-1 located on the first sub-region SAA1 can be substantially the same as the area of ​​the second Y-touch electrode line Y-TEL-2 located on the second sub-region SAA2.

[0122] Even if the first Y-touch wiring Y-TL-1 is set to pass through the first sub-region SAA1, the difference between the touch sensitivity of the first Y-touch electrode line Y-TEL-1 that generates the first sub-region SAA1 and the touch sensitivity of the second Y-touch electrode line Y-TEL-2 that generates the second sub-region SAA2 can be prevented, or the difference can be reduced.

[0123] According to embodiments of this disclosure, since the display area AA is divided into multiple sub-areas SAA, and touch is sensed by providing touch electrode lines TEL on each of the multiple sub-areas SAA, the load on the touch electrode lines TEL can be reduced and the touch sensing performance can be improved even if the area of ​​the display area AA is increased.

[0124] Furthermore, by making the areas of the touch electrode lines TELs provided on each sub-region SAA the same or similar to each other, it is possible to prevent differences in touch sensitivity caused by the touch electrode lines TELs provided on each sub-region SAA.

[0125] Each of the multiple touch electrodes TE included in the touch electrode line TEL (such as the example above) can be quadrilateral in shape, but can have various structures to improve touch sensing performance.

[0126] Figure 6 This is a diagram illustrating an example of the structure of the touch electrode TE included in the touch sensor structure of a touch display device 100 according to an embodiment of the present disclosure.

[0127] Reference Figure 6 Examples of the shapes of the X-Touch electrode X-TE included in the X-TEL and the Y-Touch electrode Y-TE included in the Y-TEL are illustrated. Figure 6 This is a diagram illustrating an example of the structure of a touch electrode TE, which exemplifies the case where the X touch electrode line X-TEL and the Y touch electrode line Y-TEL intersect each other and the X touch electrode X-TE and the Y touch electrode Y-TE are disposed on the same layer.

[0128] The X-touch electrode X-TE can have a similar shape to the Y-touch electrode Y-TE.

[0129] Using the X-Touch Electrode X-TE as an example to describe the shape of the touch electrode X-TE, the X-Touch Electrode X-TE may include at least a main body X-TE-a and multiple wings X-TE-b.

[0130] The main body X-TE-a of the X-touch electrode X-TE can be positioned in a first direction or a second direction. Figure 6 An example is shown where the main body of the X-TE, X-TE-a, is positioned in the second direction.

[0131] The wing X-TE-b of the X-touch electrode X-TE can be positioned in a direction intersecting with the main body X-TE-a. Figure 6 An example is shown where the wing X-TE-b of the X-Touch electrode X-TE is positioned in the first direction.

[0132] The width of the main body portion X-TE-a of the X-touch electrode X-TE can be the same as the width of the wing portion X-TE-b of the X-touch electrode X-TE. Alternatively, the width of the main body portion X-TE-a of the X-touch electrode X-TE can be greater than the width of the wing portion X-TE-b of the X-touch electrode X-TE.

[0133] The main body portion X-TE-a of the X-touch electrode X-TE can be configured to alternate with the main body portion Y-TE-a of the Y-touch electrode Y-TE in a first direction.

[0134] The wing X-TE-b of the X-touch electrode X-TE can be configured to alternate with the wing Y-TE-b of the Y-touch electrode Y-TE in a second direction.

[0135] The wings X-TE-b of the X-touch electrode X-TE and the wings Y-TE-b of the Y-touch electrode Y-TE can be configured to be linked together. The area of ​​the outer lines of the X-touch electrode X-TE and the Y-touch electrode Y-TE facing each other can be increased. Furthermore, the length of the boundary between the X-touch electrode X-TE and the Y-touch electrode Y-TE can be increased. Touch sensing performance based on the mutual capacitance variation between the X-touch electrode X-TE and the Y-touch electrode Y-TE can be improved.

[0136] The X-Touch Electrode (X-TE) and the Y-Touch Electrode (Y-TE) can be configured using electrodes placed on the same layer. One of the X-Touch Electrode (X-TE) and the Y-Touch Electrode (Y-TE) can be connected to an electrode placed on the same layer as the Touch Electrode (TE), while the other can be connected to an electrode placed on a different layer than the Touch Electrode (TE).

[0137] For example, the Y-touch electrode Y-TE connected in the second direction can be connected via an electrode that is disposed on the same layer as the touch electrode TE.

[0138] The X-touch electrode X-TE connected in the first direction can be electrically connected to the X-touch electrode connection pattern X-CL, which is disposed on a different layer from the touch electrode TE.

[0139] For example, the X touch electrode X-TE and the Y touch electrode Y-TE can be set using a first touch sensor metal TSM1. The X touch electrode connection pattern X-CL can be set using a second touch sensor metal TSM2.

[0140] The second touch sensor metal TSM2 can be disposed on a different layer from the first touch sensor metal TSM1.

[0141] The X-Touch Electrode X-TE and the X-Touch Electrode Connection Pattern X-CL can be electrically connected to each other through the contact hole CH.

[0142] As described above, the touch electrode line TEL can be implemented using a layer with a first touch sensor metal TSM1 and a layer with a second touch sensor metal TSM2.

[0143] By using a structure where the touch electrode TE includes a main body TE-a and a wing TE-b, the boundary between the X touch electrode X-TE and the Y touch electrode Y-TE can be increased, and touch sensing sensitivity can be improved. Furthermore, by separately setting the touch electrode lines TEL on the respective sub-regions SAA of the display area AA, the load can be reduced and touch sensing performance can be improved.

[0144] Figure 7 This is an example Figure 5 The touch sensor structure shown consists of Figure 6 The diagram shows an example of the structure of the touch electrode TE. Figure 7 Example Figure 5 The touch sensor structure implemented in the area indicated by 501 shown.

[0145] Reference Figure 6 and Figure 7 For example, the display area AA can be divided into four sub-areas SAA1, SAA2, SAA3, and SAA4 by a first boundary BL1 and a second boundary BL2. The touch electrode lines TEL set on each of the four sub-areas SAA1, SAA2, SAA3, and SAA4 can be set to be separated from each other.

[0146] The touch electrode lines (TELs) set on each sub-region SAA can include multiple X touch electrode lines (X-TELs) and multiple Y touch electrode lines (Y-TELs).

[0147] Each of the multiple X-TEL lines can include multiple X-TEL lines. Each of the multiple Y-TEL lines can include multiple Y-TEL lines. The X-TEL lines and Y-TEL lines can form a sensing unit SU.

[0148] Multiple X-Touch Electrodes (X-TEs) included in the X-Touch Electrode Line (X-TEL) can be electrically connected via the X-Touch Electrode Connection Pattern (X-CL).

[0149] For example, multiple X-touch electrodes X-TE can be made of a first touch sensor metal TSM1. The X-touch electrode connection pattern X-CL can be made of a second touch sensor metal TSM2 disposed on a different layer than the layer on which the first touch sensor metal TSM1 is disposed.

[0150] The X-touch electrode connection pattern X-CL can be arranged in the first direction and can be electrically connected to the X-touch electrode X-TE through the contact hole CH. Multiple X-touch electrodes X-TE can be electrically connected in the first direction and can form an X-touch electrode line X-TEL.

[0151] For example, the X-touch electrode connection pattern X-CL can be disposed in the area overlapping with the wing X-TE-b of the X-touch electrode X-TE. The X-touch electrode connection pattern X-CL may not be disposed in the area overlapping with the wing Y-TE-b of the Y-touch electrode Y-TE. A portion of the X-touch electrode connection pattern X-CL may overlap with the main body Y-TE-a of the Y-touch electrode Y-TE.

[0152] The width Wa1 of the wing X-TE-b of the X-Touch Electrode X-TE, which is located in the area overlapping with the X-Touch Electrode Connection Pattern X-CL, can be greater than the width Wa2 of the wing X-TE-b of the X-Touch Electrode X-TE, which is located in the area not overlapping with the X-Touch Electrode Connection Pattern X-CL.

[0153] The width Wa1 of the wing X-TE-b of the X touch electrode, which is located in the area overlapping with the X-CL connection pattern of the X touch electrode, can be greater than the width Wa3 of the wing Y-TE-b of the Y touch electrode Y-TE.

[0154] When the X-Touch Electrode Connection Pattern X-CL is configured to overlap with the wider wing X-TE-b of the X-Touch Electrode X-TE, the width or number of X-Touch Electrode Connection Patterns X-CL can be increased. The X-Touch Electrode X-TE can be electrically connected, while simultaneously reducing the resistance of the X-Touch Electrode Connection Pattern X-CL.

[0155] In areas where the X-touch electrode connection pattern X-CL is not set, when the width of the wing X-TE-b of the X-touch electrode X-TE and the width of the wing Y-TE-b of the Y-touch electrode Y-TE are relatively small, the structure with increased boundary between the X-touch electrode X-TE and the Y-touch electrode Y-TE can be maintained, and the touch sensing performance can be improved.

[0156] The X-TEL touch electrode line can be electrically connected to the X-TEL touch electrode contact pad X-CP at the boundary between the display area AA and the non-display area NA.

[0157] For example, the X-touch electrode X-TE, made of the first touch sensor metal TSM1, can be configured to extend into the non-display area NA. The X-touch electrode contact pad X-CP, made of the second touch sensor metal TSM2, can be disposed in the area overlapping with the extended X-touch electrode X-TE. The extended X-touch electrode X-TE and the X-touch electrode contact pad X-CP can be electrically connected through a contact hole CH.

[0158] Alternatively, the extension of the X-TE of the X-touch electrode disposed on the non-display area NA and the X-CP of the X-touch electrode contact pad made of the second touch sensor metal TSM2 can be regarded as the X-CP of the X-touch electrode contact pad.

[0159] The X-touch electrode contact pad X-CP can be electrically connected to the X-touch wiring X-TL on the non-display area NA. The X-touch electrode line X-TEL can be electrically connected to the X-touch wiring X-TL via the X-touch electrode contact pad X-CP. The X-touch wiring X-TL can be made of at least one of a first touch sensor metal TSM1 or a second touch sensor metal TSM2.

[0160] Multiple Y-touch electrodes (Y-TEs) included in the Y-touch electrode line (Y-TEL) can be directly connected to each other.

[0161] For example, multiple Y-touch electrodes Y-TE can be made from the first touch sensor metal TSM1. The multiple Y-touch electrodes Y-TE can be connected in a second direction and can form a Y-touch electrode line Y-TEL.

[0162] Among the multiple Y-touch electrode lines Y-TEL, the Y-touch electrode lines Y-TEL located on the second sub-region SAA2 and the fourth sub-region SAA4 can be electrically connected to the Y-touch wiring Y-TL located on the non-display area NA at the boundary between the display area AA and the non-display area NA.

[0163] For example, the second Y-touch electrode line Y-TEL-2 can be electrically connected to the second Y-touch wiring Y-TL-2 at the boundary between the display area AA and the non-display area NA. The second Y-touch wiring Y-TL-2 can be made of at least one of the first touch sensor metal TSM1 or the second touch sensor metal TSM2.

[0164] Among the multiple Y-touch electrode lines Y-TEL, the Y-touch electrode lines Y-TEL located on the first sub-region SAA1 and the third sub-region SAA3 can be electrically connected to the Y-touch wiring Y-TL on the display area AA.

[0165] For example, the first Y-touch electrode line Y-TEL-1 can be powered on and connected to the first Y-touch wiring Y-TL-1 in the display area AA.

[0166] The first Y-touch wiring Y-TL-1 can be located on the non-display area NA and the second sub-area SAA2. The first Y-touch wiring Y-TL-1 can pass through the second sub-area SAA2 and can be electrically connected to the first Y-touch electrode line Y-TEL-1 located on the first sub-area SAA1.

[0167] For example, the first Y-touch wiring Y-TL-1 can be made of the first touch sensor metal TSM1. In some cases, the second touch sensor metal TSM2 can be disposed on the area overlapping with the first Y-touch wiring Y-TL-1 and can be electrically connected to the first Y-touch wiring Y-TL-1 through the contact hole CH, thereby reducing the resistance of the first Y-touch wiring Y-TL-1.

[0168] When the first Y-touch wiring Y-TL-1 is disposed on the second sub-region SAA2, the second Y-touch electrode line Y-TEL-2 disposed on the second sub-region SAA2 can be divided and disposed on both sides of the first Y-touch wiring Y-TL-1.

[0169] The two parts of the second Y-touch electrode line Y-TEL-2 can be electrically connected to each other by connecting to the second Y-touch wiring Y-TL-2 at the boundary between the display area AA and the non-display area NA.

[0170] Furthermore, the two parts of the second Y-touch electrode line Y-TEL-2 can be electrically connected to each other via the second Y-touch electrode connection pattern Y-CL-2 set on the display area AA.

[0171] For example, the second Y-touch electrode connection pattern Y-CL-2 can be made of the second touch sensor metal TSM2.

[0172] The two portions of the second Y-touch electrode line Y-TEL-2 can be electrically connected to each other through at least one second Y-touch electrode connection pattern Y-CL-2. For example, the second Y-touch electrode connection pattern Y-CL-2 can be disposed in a region adjacent to the upper boundary of the sensing unit SU and a region adjacent to the lower boundary of the sensing unit SU, and can be electrically connected to the second Y-touch electrode line Y-TEL-2.

[0173] When the two parts of the second Y-TEL-2, which are set to be separate from each other, are connected at multiple points through the second Y-TEL connection pattern Y-CL-2, the load can be prevented from increasing due to the segmented structure of the second Y-TEL-2.

[0174] The first Y-touch wiring Y-TL-1 can pass through the second sub-region SAA2 and can be powered on in the first sub-region SAA1 to connect to the first Y-touch electrode line Y-TEL-1.

[0175] When the first Y-touch wiring Y-TL-1 passes through the second sub-region SAA2 and extends to the first sub-region SAA1, a portion of the first Y-touch wiring Y-TL-1 can be set on the first boundary BL1.

[0176] The point where the first Y-touch wiring Y-TL-1 connects to the first Y-touch electrode line Y-TEL-1 can be located inside the first sub-region SAA1. The point where the first Y-touch wiring Y-TL-1 connects to the first Y-touch electrode line Y-TEL-1 may not be located on the boundary between the first sub-region SAA1 and the second sub-region SAA2.

[0177] When the first Y-touch wiring Y-TL-1 passes through the second sub-region SAA2 and is electrically connected to the first Y-touch electrode line Y-TEL-1 disposed on the first sub-region SAA1, in a structure in which the touch electrode line TEL is divided and disposed on multiple sub-regions SAA, the touch wiring TL can be set without increasing the non-display area NA.

[0178] Since the area of ​​the second Y-touch electrode line Y-TEL-2 is reduced as the first Y-touch wiring Y-TL-1 is set on the second sub-region SAA2, the area of ​​the first Y-touch electrode line Y-TEL-1 located in the region corresponding to the second Y-touch electrode line Y-TEL-2 can be the same as or similar to the area of ​​the second Y-touch electrode line Y-TEL-2.

[0179] For example, the first Y-touch electrode line Y-TEL-1 can be configured to be divided into two parts, similar to the second Y-touch electrode line Y-TEL-2.

[0180] The two parts of the first Y-touch electrode line Y-TEL-1 can be electrically connected to each other through the first Y-touch electrode connection pattern Y-CL-1. The increased load caused by the segmented structure of the first Y-touch electrode line Y-TEL-1 can be prevented by the first Y-touch electrode connection pattern Y-CL-1.

[0181] At least one first dummy electrode DME1 may be disposed between two portions of the first Y touch electrode line Y-TEL-1.

[0182] The first dummy electrode DME1 can be configured to be electrically isolated from the first Y-touch electrode line Y-TEL-1 and the first Y-touch wiring line Y-TL-1.

[0183] The boundary between the first dummy electrode DME1 and the first Y-touch wiring Y-TL-1 may differ from the boundary between the first sub-region SAA1 and the second sub-region SAA2. The boundary between the first dummy electrode DME1 and the first Y-touch wiring Y-TL-1 may be located inside the first sub-region SAA1.

[0184] The first dummy electrode DME1 can be disposed on the first sub-region SAA1 to correspond to a portion of the first Y-touch wiring Y-TL-1 disposed on the second sub-region SAA2. The width of the first dummy electrode DME1 can be the same as or similar to the width of the first Y-touch wiring Y-TL-1.

[0185] The area of ​​the first Y-touch electrode line Y-TEL-1 disposed on the first sub-region SAA1 can be reduced to correspond to the reduction in the area of ​​the second Y-touch electrode line Y-TEL-2 due to the arrangement of the first Y-touch wiring Y-TL-1 on the second sub-region SAA2. The electrode positioned in the area remaining after the reduction of the area of ​​the first Y-touch electrode line Y-TEL-1 can become the first dummy electrode DME1.

[0186] While maintaining the touch sensitivity of the touch electrode line TEL set on the first sub-region SAA1 and the touch sensitivity of the touch electrode line TEL set on the second sub-region SAA2 the same or similar to each other, it is possible to realize a structure in which some touch wiring TL is set on the display area AA.

[0187] When the Y-Touch wiring Y-TL is set in the second direction, a portion of the Y-Touch wiring Y-TL can be positioned on the first boundary BL1.

[0188] When the second boundary BL2, which serves as the boundary of the second direction, divides the first sub-region SAA1 and the third sub-region SAA3, and the second sub-region SAA2 and the fourth sub-region SAA4, the Y-touch wiring Y-TL set in the second direction may not be set on the second boundary BL2.

[0189] The first Y-touch wiring Y-TL-1 can extend from the boundary between the display area AA and the non-display area NA to the non-display area NA and can intersect with the second Y-touch wiring Y-TL-2. In the area where the first Y-touch wiring Y-TL-1 and the second Y-touch wiring Y-TL-2 intersect, they can be set on different layers.

[0190] As described above, according to embodiments of this disclosure, a touch sensor structure capable of reducing load through the touch electrode lines TEL can be provided by dividing and arranging them on multiple sub-regions SAA. Furthermore, when a portion of the touch wiring TL is disposed on the display area AA, due to the arrangement of the touch wiring TL, a structure capable of improving touch sensing performance can be provided without a non-display area NA.

[0191] The touch electrode TE constituting the touch electrode line TEL (as in the example above) can be made of a transparent conductive material or an opaque metallic material. When the touch electrode TE is made of an opaque metallic material, it can have an open shape corresponding to the light-emitting area of ​​the sub-pixel SP, so as not to degrade the image display performance of the display panel 110. Depending on the type of sub-pixel SP, the shape of the touch electrode TE, including the open portion, can vary widely.

[0192] Figure 8 This is a diagram illustrating an example of the structure of the electrodes constituting the touch sensor structure of the touch display device 100 according to an embodiment of the present disclosure. Figure 8 Exemplary examples of the composition Figure 7 The structure of the electrodes of the touch sensor structure in the area indicated by 701 shown.

[0193] Figure 8 An example is shown of the specific structure of the electrodes constituting the main body TE-a and the wing TE-b of the aforementioned touch electrode TE. Figure 8 The electrode shown is cut in a specific direction to form the main body TE-a and wing TE-b of the touch electrode TE. Furthermore, the structure of the touch wiring TL electrically connected to the touch electrode TE can be... Figure 8 The electrodes shown have the same structure.

[0194] Reference Figure 8 An exemplary embodiment illustrates a structure in which a display signal line DSL, which supplies signals for display driving, is disposed on a display panel 110 and a touch electrode TE is disposed thereon.

[0195] The display signal line DSL may include multiple first display signal lines DSL1 disposed in a first direction and multiple second display signal lines DSL2 disposed in a second direction.

[0196] For example, the first display signal line DSL1 can be a gating line GL or an illumination control line EML. For example, the second display signal line DSL2 can be a data line DL or a line supplying at least one of a first driving voltage VDD, a reference voltage Vref, or a second driving voltage VSS.

[0197] For example, the touch electrode TE may include a first portion TE_f disposed in a first direction, a second portion TE_s disposed in a second direction, and a third portion TE_t disposed in a third direction different from the first and second directions.

[0198] The electrodes constituting the touch electrode TE can be cut in a first direction (e.g., the portion indicated by 801) or in a second direction (e.g., the portion indicated by 802) to form the X touch electrode TE or the Y touch electrode Y-TE.

[0199] The electrode, which includes the first part TE_f, the second part TE_s, and the third part TE_t, can be cut in the first direction or the second direction, and can form the main body TE-a or the wing TE-b of the aforementioned touch electrode TE.

[0200] The touch wiring TL may be similar to the touch electrode TE, including at least some of a first part TE_f, a second part TE_s, or a third part TE_t, and may be cut in a first direction or a second direction.

[0201] When the touch electrode TE is formed to include a first portion TE_f, a second portion TE_s, and a third portion TE_t disposed in different directions from each other, the touch electrode TE may include multiple open portions. The shape of the open portions of the touch electrode TE can vary and can be determined according to the shape of the light-emitting area of ​​the sub-pixel SP disposed on the display panel 110.

[0202] Figure 9 This is a diagram illustrating an example of the arrangement relationship between the electrodes constituting the touch sensor structure and the configuration included in the sub-pixel SP in a touch display device 100 according to an embodiment of the present disclosure. Figure 9 Exemplary examples of the composition Figure 7 The structure of the electrodes of the touch sensor structure in the area indicated by 702 shown. Figure 10 This is an example Figure 9 A diagram showing an example of the cross-sectional structure of the A-A' section.

[0203] Reference Figure 9 and Figure 10 The light-emitting area of ​​the light-emitting element ED set on the sub-pixel SP can be positioned on the area overlapping with the open portion of the touch electrode TE.

[0204] The light-emitting area of ​​the light-emitting element ED can refer to the area where the light-emitting layer EL and the second electrode E2 are disposed on the first electrode E1 of the light-emitting element ED. Furthermore, the light-emitting area of ​​the light-emitting element ED can refer to the area within the region where the first electrode E1 of the light-emitting element ED is disposed, where the embankment BNK is not disposed.

[0205] Figure 9 An example of the shape of the light-emitting area setting of the red sub-pixel SP_r, the green sub-pixel SP_g, and the blue sub-pixel SP_b is shown. The shape and size of the sub-pixel SP that constitute a pixel can vary depending on the display panel 110.

[0206] The first part TE_f, the second part TE_s, and the third part TE_t of the touch electrode TE can be set to avoid the light-emitting area of ​​the sub-pixel SP.

[0207] Touch electrodes TE can be positioned between the light-emitting areas of adjacent sub-pixels SP, and can prevent or minimize the impact of touch electrodes TE on image display based on viewing angle.

[0208] Since the touch electrode TE is positioned away from the light-emitting area of ​​the sub-pixel SP, the touch electrode TE can be configured to overlap with a specific structure located on the sub-pixel SP.

[0209] For example, the first portion TE_f of the touch electrode TE disposed in the first direction can be configured to overlap with at least a portion of the contact hole CH to facilitate electrical connection between the first electrode E1 of the light-emitting element ED and the thin-film transistor TFT on the sub-pixel SP.

[0210] Reference Figure 9 and Figure 10 In Example 1, a multi-buffer layer MB can be disposed on a substrate SUB. For example, the substrate SUB may include a first polyimide layer PI1, an interlayer polyimide layer IPD, and a second polyimide layer PI2. The multi-buffer layer MB may be a structure in which multiple insulating layers are laminated.

[0211] The light-shielding metal layer (BSM) can be disposed on the multi-buffered layer (MB). The light-shielding metal layer (BSM) can form part of the display signal line (DSL), or it can form part of the storage capacitor (Cstg) disposed on the sub-pixel (SP).

[0212] The active buffer layer AB can be set on the light-shielding metal layer BSM.

[0213] The active layer ACT can be disposed on the active buffer layer AB. The active layer ACT can be made of semiconductor material.

[0214] The active layer ACT can form the channel of a thin-film transistor (TFT). Furthermore, the active layer ACT can be used to form a portion of the display signal line DSL or the storage capacitor Cstg by conducting electricity.

[0215] The gate insulating layer GI can be disposed on the active layer ACT.

[0216] The gate metal layer (GAT) can be disposed on the gate insulating layer (GI). The gate metal layer (GAT) can form the gate electrode of a thin-film transistor (TFT) or a display signal line (DSL), etc.

[0217] The first interlayer insulating layer ILD1 can be disposed on the gate metal layer GAT.

[0218] The display auxiliary electrode layer TM can be disposed on the first interlayer insulating layer ILD1. The display auxiliary electrode layer TM can be used in various ways to form the display signal line DSL or the storage capacitor Cstg, etc.

[0219] The second interlayer insulating layer ILD2 can be disposed on the display auxiliary electrode layer TM.

[0220] The source / drain metal layer SD can be disposed on the second interlayer insulating layer ILD2. The source / drain metal layer SD can constitute the source and drain electrodes of a thin-film transistor (TFT), or it can constitute a display signal line DSL, etc.

[0221] The planarization layer PLN can be set on the source / drain metal layer SD.

[0222] The first electrode E1 of the light-emitting element ED can be disposed on the planarization layer PLN. The first electrode E1 of the light-emitting element ED can be electrically connected to a thin-film transistor TFT located below the planarization layer PLN through a contact hole CH formed in the planarization layer PLN. For example, the thin-film transistor TFT electrically connected to the first electrode E1 of the light-emitting element ED can be a driving transistor DRT, or it can be a transistor that controls the timing of light emission of the light-emitting element ED (such as...). Figure 2 (Example).

[0223] The dam BNK can be disposed on the planarization layer PLN and the first electrode E1 of the light-emitting element ED. The dam BNK can be configured to cover the edge portion of the first electrode E1 of the light-emitting element ED.

[0224] The light-emitting layer EL of the light-emitting element ED and the second electrode E2 can be disposed on the portion of the first electrode E1 exposed through the dam BNK and on the dam BNK. The portion of the first electrode E1 exposed through the dam BNK can correspond to the light-emitting area.

[0225] The encapsulation layer ENCAP can be disposed on the second electrode E2 of the light-emitting element ED. The encapsulation layer ENCAP may include multiple layers. The encapsulation layer ENCAP may include at least one inorganic layer and at least one organic layer.

[0226] For example, the encapsulation layer ENCAP may include a first inorganic encapsulation layer PAS1, an organic encapsulation layer PCL, and a second inorganic encapsulation layer PAS2.

[0227] For example, the inorganic encapsulation layers PAS1 and PAS2 can be made of inorganic insulating materials such as silicon nitride (SiNx), silicon oxide (SiOx), silicon oxynitride (SiON), or aluminum oxide (Al2O3), which can be deposited at low temperatures. Similarly, the organic encapsulation layer PCL can be made of organic insulating materials such as acrylic resin, epoxy resin, polyimide, polyethylene, or silicon-oxygen-carbon (SiOC).

[0228] The ENCAP encapsulation layer can seal the LED and protect it from moisture and air.

[0229] The touch sensor structure used for touch sensing can be implemented on the encapsulation layer ENCAP.

[0230] For example, a touch buffer layer (TBUF) can be placed on the encapsulation layer (ENCAP). The touch buffer layer (TBUF) can be an inorganic layer. In some cases, a touch buffer layer (TBUF) may not be necessary, but it can be placed to facilitate the placement of the touch sensor metal (TSM) on the encapsulation layer (ENCAP).

[0231] The touch insulation layer TILD can be set on the touch buffer layer TBUF.

[0232] even though Figure 10 Not shown, but the second touch sensor metal TSM2, which constitutes the touch electrode connection pattern CL, can be disposed between the touch buffer layer TBUF and the touch insulating layer TILD.

[0233] The touch insulating layer (TILD) can be an inorganic layer. Alternatively, the touch insulating layer (TILD) can be an organic layer.

[0234] When the touch insulating layer TILD is an organic layer, the thickness of the touch insulating layer TILD can be greater than the thickness of the touch buffer layer TBUF.

[0235] Furthermore, when the touch insulating layer TILD is an organic layer (e.g., Figure 10 (Example 2) The touch insulating buffer layer TIBUF may be further disposed between the touch insulating layer TILD and the touch buffer layer TBUF. As described above, two or more buffer layers may be disposed between the encapsulation layer ENCAP and the touch insulating layer TILD.

[0236] A touch insulating buffer layer (TIBUF) can be disposed between the touch insulating layer (TILD) and the second touch sensor metal (TSM2). The touch insulating buffer layer (TIBUF) can be an inorganic layer. The touch insulating buffer layer (TIBUF) can be made of the same material as the touch buffer layer (TBUF).

[0237] At least a portion of the TILD touch insulation layer can be configured to contact the top surface of the TIBUF touch insulation buffer layer.

[0238] When the touch insulating buffer layer TIBUF, made of an inorganic layer, is placed between the touch insulating layer TILD and the second touch sensor metal TSM2, the adhesion of the touch insulating layer TILD, which is an organic layer, can become easier.

[0239] The thickness of the touch insulating buffer layer TIBUF can be less than the thickness of the touch insulating layer TILD, and can be similar to the thickness of the touch buffer layer TBUF.

[0240] The touch electrode TE can be disposed on the touch insulating layer TILD. The first touch sensor metal TSM1 can be disposed on the touch insulating layer TILD and can constitute the touch electrode TE. In addition, the first touch sensor metal TSM1 can be disposed on the touch insulating layer TILD and can constitute the touch wiring TL.

[0241] Figure 10 Example of setting Figure 9 The diagram shows a cross-sectional structure of a portion of the first part TE_f of the touch electrode TE. The first part TE_f of the touch electrode TE can be disposed on the touch insulating layer TILD.

[0242] The first portion TE_f of the touch electrode TE can be configured to avoid the light-emitting area of ​​the light-emitting element ED. The first portion TE_f of the touch electrode TE can be disposed in an area overlapping at least a portion of the contact hole CH to facilitate electrical connection between the first electrode E1 of the light-emitting element ED and the thin-film transistor TFT.

[0243] The first part TE_f of the touch electrode TE can be located between adjacent display signal lines DSL arranged along a first direction, or it can be located to overlap with a part of the display signal line DSL.

[0244] When the touch electrode TE is positioned on the area overlapping with the contact hole CH and is configured to avoid the light-emitting area of ​​the light-emitting element ED, a touch sensor structure can be implemented without degrading the image display function of the display panel 110.

[0245] The touch protection layer TPAS can be applied to the touch electrode TE, which is made of the first touch sensor metal TSM1, and can protect the touch electrode TE.

[0246] As described above, since the portions of the electrodes constituting the touch electrode TE or touch wiring TL are located in areas that do not overlap with the light-emitting area of ​​the light-emitting element ED located on the sub-pixel SP and are located in positions that minimize the interruption of the viewing angle of the light-emitting area, the touch sensor structure can be realized while preventing or minimizing the degradation of the image display performance of the display panel 110.

[0247] Below, will describe Figure 5 The illustrated touch sensor structure is a specific example implemented by a touch electrode TE having the electrode structure described above and touch wiring TL. Furthermore, as mentioned above, the touch electrode TE can have various shapes other than the electrode structure described above, and the embodiments of this disclosure can be applied to various electrode structures.

[0248] Figures 11 to 15 This is a diagram illustrating a specific example of a touch sensor structure of a touch display device 100 according to an embodiment of the present disclosure being implemented on a display area AA of a display panel 110.

[0249] Figure 11 An example of the structure of a touch electrode TE is shown, located on a region that divides a display area AA into sub-regions SAA. Figure 12 An example of the structure of the touch wiring TL and dummy electrode DME set on the display area AA is shown. Figure 13 An example is shown illustrating the boundary between the touch wiring TL and the dummy electrode DME on the display area AA.

[0250] Figure 14 Another example of the structure of the touch wiring TL and dummy electrode DME set on the display area AA is shown. Figure 15 This is yet another example of a touch wiring TL set on the display area AA.

[0251] Reference Figure 11 The display area AA of the display panel 110 can be divided into multiple sub-regions SAA by a first boundary BL1 and a second boundary BL2. Touch electrode lines TEL disposed on each of the multiple sub-regions SAA can be configured to be separate from each other. For ease of illustration, an example is shown. Figure 11 The schematic diagram of the overall structure of the display panel 110 illustrates the portion made of the first touch sensor metal TSM1.

[0252] Some touch electrode lines TELs located on multiple sub-regions SAA can be electrically connected to touch wiring TLs located on the non-display area NA at the boundary between the display area AA and the non-display area NA.

[0253] Other touch electrode lines TELs located on multiple sub-regions SAA can be electrically connected to touch wiring TLs configured to pass through the display region AA from the non-display region NA.

[0254] The touch electrode TE constituting the touch electrode line TEL may include at least one main body TE-a and multiple wings TE-b.

[0255] Touch electrode lines TEL and touch wiring TL can be implemented by cutting electrodes comprising a first part TE_f, a second part TE_s, and a third part TE_t in a specific direction.

[0256] For example, electrodes can be cut at the boundary between the X touch electrode line (X-TEL) and the Y touch electrode line (Y-TEL). Electrodes can also be cut at the boundaries of the touch wiring line (TL), the dummy electrode line (DME), and the touch electrode line (TEL). Furthermore, electrodes can be cut at the boundary of the sub-region (SAA).

[0257] Reference Figure 11 The electrode can be cut on the first boundary BL1 in a first direction. The electrode can be cut on the second boundary BL2 in a second direction.

[0258] By cutting electrodes on the first boundary BL1 and the second boundary BL2, the touch electrode line TEL disposed on each of the first sub-region SAA1, the second sub-region SAA2, the third sub-region SAA3 and the fourth sub-region SAA4 can be divided.

[0259] The X-TEL and Y-TEL touch electrode lines set on each sub-region SAA can be implemented by cutting the electrodes in a first direction or a second direction.

[0260] The space between touch electrodes TE on the boundary of sub-region SAA can be the same as or similar to the space between touch electrodes TE inside sub-region SAA. Since the space between the cut electrodes is substantially the same, no difference in visibility is generated depending on the area of ​​the display panel 110.

[0261] Touch wiring (TL) and dummy electrode (DME) can be implemented by cutting the electrodes in a manner similar to that of touch electrode line (TEL).

[0262] Reference Figure 12 The portion indicated by 1201 illustrates an example of a region where the first dummy electrode DME1 is disposed on the first sub-region SAA1. The portion indicated by 1202 illustrates an example of a region where the first Y-touch wiring Y-TL-1 is disposed on the second sub-region SAA2.

[0263] The first Y-touch wiring Y-TL-1 can be set by cutting the electrodes set on the second sub-region SAA2.

[0264] The first Y-touch wiring Y-TL-1 can be positioned between two portions of the second Y-touch electrode line Y-TEL-2 on the second sub-region SAA2.

[0265] At least one first dummy electrode DME1 can be set by cutting the electrode set on the first sub-region SAA1. At least one first dummy electrode DME1 can be positioned on the region in the first sub-region SAA1 corresponding to the region on the second sub-region SAA2 where the first Y-touch wiring Y-TL-1 is set.

[0266] The first dummy electrode DME1 can be positioned between the first Y-touch electrode lines Y-TEL-1 on the first sub-region SAA1. Multiple first dummy electrodes DME1 can be separated from each other and can be, for example... Figure 12 The example setup shown is such that no defects occur even if a portion of the first dummy electrode DME1 is short-circuited.

[0267] A first dummy electrode DME1, electrically separated from the first Y-touch electrode line Y-TEL-1, can be positioned between the first Y-touch electrode lines Y-TEL-1 in the first sub-region SAA1. A first Y-touch wiring Y-TL-1, electrically separated from the second Y-touch electrode line Y-TEL-2, can be positioned between the second Y-touch electrode lines Y-TEL-2 in the second sub-region SAA2.

[0268] The first dummy electrode DME1 and the first Y-touch wiring Y-TL-1 can be configured to correspond to each other. The width of the area where the first dummy electrode DME1 is configured can be the same as or similar to the width of the area where the first Y-touch wiring Y-TL-1 is configured. That is, the lower touch sensor portion can include the area through which the first Y-touch wiring Y-TL-1 of the upper touch sensor portion passes, and in the upper touch sensor portion, the first dummy electrode DME1 can be configured on the area corresponding to the first Y-touch wiring Y-TL-1 configured on the lower touch sensor portion.

[0269] At least one second dummy electrode DME2 can be set by cutting the electrode portion between the first Y-touch wiring Y-TL-1 and the second Y-touch electrode line Y-TEL-2 on the second sub-region SAA2.

[0270] The second dummy electrode DME2 can be configured to be electrically isolated from the first Y-touch wiring Y-TL-1 and the second Y-touch electrode line Y-TEL-2.

[0271] The first dummy electrode DME1 can be positioned on the portion of the first sub-region SAA1 corresponding to the region on the second sub-region SAA2 where the second dummy electrode DME2 is located. Some first dummy electrodes DME1 can be configured to correspond to the second dummy electrodes DME2.

[0272] The second dummy electrode DME2 can be configured to prevent or reduce the decrease in visibility caused by the arrangement of touch electrode lines TEL. Alternatively, the second dummy electrode DME2 can be configured to prevent short circuits between the first Y-touch wiring Y-TL-1 and the second Y-touch electrode line Y-TEL-2.

[0273] A first dummy electrode DME1 can be set, or a first Y-touch wiring Y-TL-1 and a second dummy electrode DME2 can be set on corresponding areas in the first sub-region SAA1 and the second sub-region SAA2. The area of ​​the Y-touch electrode line Y-TEL set on each of the first sub-region SAA1 and the second sub-region SAA2 can be the same or similar. The space between the two parts of the first Y-touch electrode line Y-TEL-1 separately set on both sides of the first dummy electrode DME1 in the first sub-region SAA1 can be the same or similar to the space between the two parts of the second Y-touch electrode line Y-TEL-2 separately set on both sides of the first Y-touch wiring Y-TL-1 in the second sub-region SAA2.

[0274] The first dummy electrode DME1 and the second dummy electrode DME2 can be set by cutting the electrode in a manner similar to cutting the electrode in the touch electrode line TEL or touch wiring TL. The dummy electrode DME can be set by cutting the electrode in a first direction or a second direction, similar to cutting the electrode in the touch electrode line TEL.

[0275] Alternatively, at least one of the first dummy electrode DME1 or the second dummy electrode DME2 may be configured to be cut in a direction different from the direction in which the touch electrode line TEL and the touch wiring TL are cut.

[0276] For example, as described above, touch electrode lines TEL and touch wiring TL can be configured by cutting electrodes in a first direction or a second direction. However, the first dummy electrode DME1 and the second dummy electrode DME2 can be configured by cutting electrodes in a direction other than the first and second directions. The two sides (ends) of each of the first dummy electrode DME1 and the second dummy electrode DME2 can be in a shape cut in a third direction different from the first and second directions.

[0277] For example, a dummy electrode DME can be configured by cutting an electrode diagonally at the boundary between the dummy electrode DME and the touch electrode line TEL or touch wiring TL. The two sides of the dummy electrode DME can be in a diagonally cut shape. When the boundary of the dummy electrode DME is in a diagonally cut shape, the area of ​​the end of the dummy electrode DME can be larger than the area of ​​the end of the touch electrode line TEL or the end of the touch wiring TL.

[0278] The boundary between touch electrode lines TEL and the boundary between touch electrode lines TEL and touch wiring TL can be the shape of cutting electrodes in a first direction or a second direction.

[0279] The boundaries between the dummy electrode DME and the touch electrode line TEL, the boundaries between the dummy electrode DME and the touch wiring TL, and the boundaries between the dummy electrodes DME can be shapes cut in a third direction (e.g., a diagonal direction) different from the first and second directions.

[0280] The dummy electrode (DME) may have a shape that cuts the electrode diagonally at the boundary of the dummy electrode (DME). The touch electrode line (TEL) or touch wiring line (TL) may include a protrusion that protrudes toward the dummy electrode (DME) and has a shape that cuts diagonally at the boundary between the dummy electrode (DME) and the touch electrode line (TEL) or touch wiring line (TL).

[0281] Because the cutting direction of the boundary of the dummy electrode DME is different from the cutting direction of the boundary of the touch electrode line TEL or the touch wiring TL, the repair process can be easier during the inspection of the touch sensor structure.

[0282] For example, if there is a short circuit between electrodes on the boundary of the cut electrodes in the first or second direction, since the corresponding area is the boundary between touch electrode lines TEL or the boundary between touch electrode line TEL and touch wiring TL, a repair process of cutting the short circuit is required.

[0283] In the case where a short circuit exists between electrodes at the boundary of the diagonally cut electrodes, since at least one short-circuited electrode is a dummy electrode (DME), the touch sensor structure may not be affected even if the short circuit is not cut. Therefore, the inspection process can be terminated without a repair process. In this case, the dummy electrode (DME) can be configured to connect to the touch electrode line (TEL) or touch wiring (TL) on the display area (AA).

[0284] As described above, by arranging dummy electrodes (DMEs), the area of ​​the touch electrode lines (TELs) can be made uniform, and visibility can be improved. Furthermore, since the cutting direction at the boundary of the dummy electrodes (DMEs) differs from the cutting direction at the boundary of the touch electrode lines (TELs), the efficiency of the inspection process can be increased.

[0285] Although the above examples describe the case where the dummy electrode DME is only placed in the area corresponding to the touch wiring TL or the periphery of the touch wiring TL, in some cases, the dummy electrode DME can be placed inside the touch electrode line TEL or in the boundary area between touch electrode lines TEL. In this case, the dummy electrode DME can be uniformly positioned in each area.

[0286] The boundary between the first dummy electrode DME1 disposed on the first sub-region SAA1 and the first Y touch wiring Y-TL-1 electrically connected to the first Y touch electrode line Y-TEL-1 of the first sub-region SAA1 can be cut in a similar manner.

[0287] Reference Figure 13 The portion indicated by 1301 represents the boundary between the first Y-touch wiring Y-TL-1 and the first dummy electrode DME1.

[0288] The boundary between the first Y-touch wiring Y-TL-1 and the first dummy electrode DME1 can be a shape in which the electrode is cut diagonally.

[0289] Alternatively, in some cases, the boundary between the first Y-touch wiring Y-TL-1 and the first dummy electrode DME1 may be a shape cut in the first direction. When multiple first dummy electrodes DME1 are configured to be separated from each other, the boundary of only the first dummy electrode DME1 most adjacent to the first Y-touch wiring Y-TL-1 may not be a shape cut in the diagonal direction.

[0290] When the first Y-touch wiring Y-TL-1 is electrically connected to the first Y-touch electrode line Y-TEL-1 disposed on the first sub-region SAA1, the boundary between the first Y-touch wiring Y-TL-1 and the first dummy electrode DME1 may be different from the boundary between the first sub-region SAA1 and the second sub-region SAA2. For example, the boundary between the first Y-touch wiring Y-TL-1 and the first dummy electrode DME1 may be located inside the first sub-region SAA1.

[0291] The first Y-touch wiring Y-TL-1 can be directly connected to the first Y-touch electrode line Y-TEL-1 inside the first sub-region SAA1. The first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 can be directly connected to each other because they are both made of the first touch sensor metal TSM1.

[0292] Alternatively, the first Y-touch wiring Y-TL-1 can be electrically connected to the first Y-touch electrode line Y-TEL-1 via a first Y-touch electrode connection pattern Y-CL-1 made of the second touch sensor metal TSM2.

[0293] The first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 can be electrically connected to each other via the first Y-touch electrode connection pattern Y-CL-1 positioned on the upper side of the first boundary BL1. The two parts of the second Y-touch electrode line Y-TEL-2 disposed on the second sub-region SAA2 can be electrically connected to each other via the second Y-touch electrode connection pattern Y-CL-2 positioned on the lower side of the first boundary BL1.

[0294] When the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 are connected by the first Y-touch electrode connection pattern Y-CL-1, the first Y-touch wiring Y-TL-a and the first Y-touch electrode line Y-TEL-1 can be connected to each other or can be separated from each other on the layer on which the first touch sensor metal TSM1 is provided.

[0295] When the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 are configured to be separated from each other on the layer where the first touch sensor metal TSM1 is disposed, the boundary between the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 can be diagonally shaped. Since even if the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 made of the first touch sensor metal TSM1 are short-circuited, no repair process for cutting is required. Therefore, for process convenience, the boundary between the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 made of the first touch sensor metal TSM1 can be cut diagonally in the process of cutting the dummy electrode DME.

[0296] As described above, the first Y-touch wiring Y-TL-1 and the first Y-touch electrode line Y-TEL-1 can be electrically connected to each other in various shapes on the first sub-region SAA1. In order to reduce the load on the first Y-touch electrode line Y-TEL-1 disposed on the display area AA, a pattern for reducing resistance can be further disposed on the first Y-touch wiring Y-TL-1.

[0297] Reference Figure 14The portion indicated by 1401 illustrates an example of a region where the first dummy electrode DME1 is disposed on the first sub-region SAA1. The portion indicated by 1402 illustrates an example of a region where the first Y-touch wiring Y-TL-1 and the second dummy electrode DME2 are disposed on the second sub-region SAA2. The lower touch sensor portion has a region through which the first Y-touch wiring Y-TL-1 of the upper touch sensor portion passes, and the first dummy electrode DME1 may be disposed on the region of the upper touch sensor portion corresponding to the region of the first Y-touch wiring Y-TL-1 disposed on the lower touch sensor portion.

[0298] Referring to the portion indicated by 1402, at least one Y-auxiliary wiring pattern Y-TLP made of the second touch sensor metal TSM2 may be disposed on the area of ​​the second sub-region SAA2 that overlaps with the first Y touch wiring Y-TL-1 made of the first touch sensor metal TSM1.

[0299] The Y-auxiliary wiring pattern Y-TLP can be set on an area other than the area where the X-touch electrode connection pattern X-CL or the Y-touch electrode connection pattern Y-CL made of the second touch sensor metal TSM2 is set. The Y-auxiliary wiring pattern Y-TLP can be set separately from the X-touch electrode connection pattern X-CL and the Y-touch electrode connection pattern Y-CL.

[0300] The Y-auxiliary wiring pattern Y-TLP can be configured to overlap with at least a portion of the first Y-touch wiring Y-TL-1.

[0301] The Y-auxiliary wiring pattern Y-TLP can be electrically connected to the first Y-touch wiring Y-TL-1 at at least one point via a contact hole CH.

[0302] Since the Y-auxiliary wiring pattern Y-TLP is electrically connected to the first Y-touch wiring Y-TL-1, the resistance of the first Y-touch wiring Y-TL-1 can be reduced. This reduces the load on the first Y-touch wiring Y-TL-1 located on the display area AA.

[0303] Referring to the portion indicated by 1401, at least one dummy pattern DMP made of the second touch sensor metal TSM2 may be disposed on the area of ​​the first sub-region SAA1 that overlaps with the first dummy electrode DME1.

[0304] The dummy pattern DMP can have the same or similar shape as the first dummy electrode DME1. The boundary of the dummy pattern DMP can be diagonal, such as the boundary of the first dummy electrode DME1. The dummy pattern DMP can be electrically connected to the first dummy electrode DME1, or it can be insulated from the first dummy electrode DME1. The dummy pattern DMP and the first dummy electrode DME1 can be floated.

[0305] Since the Y-assisted wiring pattern Y-TLP is set on the area of ​​the second sub-region SAA2 that overlaps with the first Y-touch wiring Y-TL-1, the visibility difference based on the sub-region SAA can be prevented by arranging the dummy pattern DMP on the area of ​​the first sub-region SAA1 that overlaps with the first dummy electrode DME1.

[0306] In addition, the width of the Y-assisted wiring pattern Y-TLP or the dummy pattern DMP can be adjusted within a range without affecting visibility.

[0307] Reference Figure 15 This example illustrates an area where the first Y-touch wiring Y-TL-1 and the Y-auxiliary wiring pattern Y-TLP are set on the second sub-region SAA2.

[0308] The Y-auxiliary wiring pattern Y-TLP can be set in the area that overlaps with the first Y-touch wiring Y-TL-1.

[0309] The Y-auxiliary wiring pattern Y-TLP can be electrically connected to the first Y-touch wiring Y-TL-1 via the contact hole CH.

[0310] The width of the Y-auxiliary wiring pattern Y-TLP can be different from the width of the first Y-touch wiring Y-TL-1.

[0311] For example, the width Wb2 of the Y-assisted wiring pattern Y-TLP can be greater than the width Wb1 of the first Y-touch wiring Y-TL-1.

[0312] Furthermore, since the first Y-touch wiring Y-TL-1 and the Y-auxiliary wiring pattern Y-TLP are configured to avoid the light-emitting area of ​​the light-emitting element ED, the first Y-touch wiring Y-TL-1 and the Y-auxiliary wiring pattern Y-TLP may include open portions corresponding to the light-emitting area of ​​the light-emitting element ED. Because the width of the Y-auxiliary wiring pattern Y-TLP is greater than the width of the first Y-touch wiring Y-TL-1, the size of the open portion included in the first Y-touch wiring Y-TL-1 may be larger than the size of the open portion included in the Y-auxiliary wiring pattern Y-TLP, and corresponding to the open portion included in the first Y-touch wiring Y-TL-1.

[0313] Since the Y-auxiliary wiring pattern Y-TLP is located below the first Y-touch wiring Y-TL-1, it can be positioned further away from the outside of the display panel 110 than the first Y-touch wiring Y-TL-1. Even if the width of the Y-auxiliary wiring pattern Y-TLP is greater than the width of the first Y-touch wiring Y-TL-1, the degree of visibility reduction can be smaller compared to the width of the first Y-touch wiring Y-TL-1 being greater than the width of the Y-auxiliary wiring pattern Y-TLP.

[0314] Because the width of the Y-TLP auxiliary wiring pattern is increased while preventing or minimizing visibility loss, the resistance of the first Y-touch wiring Y-TL-1, which is electrically connected to the Y-TLP auxiliary wiring pattern, can be reduced even further.

[0315] Furthermore, in this case, the width of the dummy pattern DMP overlapping with the first dummy electrode DME1 disposed on the first sub-region SAA1 can be greater than the width of the first dummy electrode DME1. By increasing the width of the dummy pattern DMP located below the first dummy electrode DME1, visibility differences between the first sub-region SAA1 and the second sub-region SAA2 can be prevented or reduced.

[0316] As described above, by arranging the auxiliary wiring pattern TLP in the area overlapping with the touch wiring TL set on the display area AA, the load on the touch wiring TL can be reduced and the touch sensing performance can be improved without degrading the image display performance.

[0317] As described above, according to the embodiments of this disclosure, by implementing a touch sensor structure using a first touch sensor metal TSM1 and a second touch sensor metal TSM2 on the display area AA, a touch sensor structure that improves touch sensing performance while minimizing the impact on image display performance can be provided.

[0318] Figure 16 This is a diagram illustrating a specific example of a touch sensor structure of a touch display device 100 according to an embodiment of the present disclosure being implemented on the peripheral region of the boundary between the display area AA and the non-display area NA of the display panel 110. Figure 16 An exemplary embodiment shows that the second touch sensor metal TSM2 is disposed... Figure 7 The specific structure in the area indicated by 703 shown.

[0319] Reference Figure 16 This illustrates an example of the structure of a second touch sensor metal TSM2 disposed on a region including a sensing unit SU on one side boundary of the display area AA.

[0320] The X-touch electrode connection pattern X-CL, used for connecting the X-touch electrode X-TE, can be set on the display area AA. The X-touch electrode connection pattern X-CL can be connected to the X-touch electrode contact pad X-CP, which is located outside the display area AA. The X-touch electrode contact pad X-CP can be connected to the X-touch wiring X-TL.

[0321] At least one Y-touch electrode connection pattern Y-CL made of the second touch sensor metal TSM2 can be disposed in the area adjacent to the upper and lower boundaries of the sensing unit SU.

[0322] The Y-Touch Electrode Connection Pattern Y-CL electrically connects the two parts of the Y-Touch Electrode Line Y-TEL, which are separated by the Y-Touch Wiring Y-TL or the first dummy electrode DME1.

[0323] Two or more Y-touch electrode connection patterns Y-CL can be disposed on a sensing unit SU, and the Y-touch electrode connection patterns Y-CL can be disposed in various positions. Since the Y-touch electrode connection patterns Y-CL connect the Y-touch electrodes Y-TE that are separated on the upper and lower sides of each sensing unit SU, the Y-touch electrodes Y-TE can have a state similar to the non-separated structure.

[0324] Since the Y-touch electrode connection pattern Y-CL is positioned on the upper and lower boundaries of the sensing unit SU, the points of the X-touch electrode contact pads X-CP connected to the X-touch electrode line X-TEL can be positioned between adjacent Y-touch electrode connection patterns Y-CL.

[0325] For example, as indicated in 1601, the boundary between the X-touch contact pads X-CP can be the same as the boundary of the sensing unit SU.

[0326] Since the Y-CL touch electrode connection pattern is set on both sides of the boundary of the sensing unit SU, the boundary between the X-CP touch electrode contact pads can be positioned between adjacent Y-CL touch electrode connection patterns.

[0327] The Y-TLP auxiliary wiring pattern can be set on an area other than the area where the X-CL touch electrode connection pattern and the Y-CL touch electrode connection pattern are set on the layer where the second touch sensor metal TSM2 is located.

[0328] The Y-auxiliary wiring pattern Y-TLP can be configured to be separate from the X-touch electrode connection pattern X-CL and the Y-touch electrode connection pattern Y-CL. The Y-auxiliary wiring pattern Y-TLP can be electrically connected to the Y-touch wiring Y-TL that overlaps with the Y-auxiliary wiring pattern Y-TLP, and can reduce the resistance of the Y-touch wiring Y-TL located on the display area AA.

[0329] The second touch sensor metal TSM2, which is disposed in the area overlapping with the first dummy electrode DME1, can be configured to have a similar shape to the first dummy electrode DME1 and can form a dummy pattern DMP.

[0330] The dummy pattern DMP can be set in an area other than the area where the X touch electrode connection pattern X-CL, Y touch electrode connection pattern Y-CL, and Y auxiliary wiring pattern Y-TLP are set on the layer where the second touch sensor metal TSM2 is located. Since the dummy pattern DMP is set in the area that overlaps with the touch electrode line TEL, the visibility difference between the areas where the touch wiring TL and the auxiliary wiring pattern TLP are set to overlap with each other can be prevented.

[0331] Since the X-touch wiring X-TL, which only drives the X-touch electrode line X-TEL located on the corresponding sub-region SAA, is located on the boundary areas on both sides of the display area AA, the X-touch wiring X-TL can be easily arranged. The X-touch wiring X-TL can be made of at least one of the first touch sensor metal TSM1 or the second touch sensor metal TSM2, and can be implemented in a shape that reduces line resistance.

[0332] Figure 17 This is a diagram illustrating a specific example of a touch sensor structure of a touch display device 100 according to an embodiment of the present disclosure being implemented between the display area AA and the non-display area NA dam DM of the display panel 110.

[0333] Reference Figure 17 At least one dam DM can be disposed on the non-display area NA of the display panel 110. At least one dam DM can be disposed around the display area AA. At least one dam DM can be positioned outside the encapsulation layer ENCAP. At least one dam DM can be part of the encapsulation layer ENCAP.

[0334] Multiple touch traces TL can be positioned inside at least one dam DM on the non-display area NA. Multiple touch traces TL can be positioned between at least one dam DM on the area outside the display area AA and the pad area PA.

[0335] Since multiple touch wiring TLs are positioned inside at least one dam DM, touch wiring TLs can be configured while minimizing the increase in the non-display area NA.

[0336] At least one shield line SHL can be configured to surround at least a portion of multiple touch wiring TLs. The shield line SHL can be positioned between the outermost touch wiring TL and the dam DM.

[0337] The shielding wire SHL can be made of the same material as the touch wiring TL. For example, the shielding wire SHL can be made of at least one of the first touch sensor metal TSM1 or the second touch sensor metal TSM2.

[0338] The shielded wire SHL can be grounded. Alternatively, the shielded wire SHL can receive signals different from those supplied via the touch wiring TL.

[0339] Because the shielding line SHL is configured to surround the outside of the touch wiring TL, the shielding line SHL can block external noise and prevent or reduce external noise from affecting the signal of the touch wiring TL.

[0340] At least one protection line (GUL) can be placed between the touch wiring TL and the shielding line (SHL).

[0341] The protective line GUL can be made of the same material as the touch wiring TL. For example, the protective line GUL can be made of at least one of the first touch sensor metal TSM1 or the second touch sensor metal TSM2.

[0342] Because the guard line (GUL) is positioned between the touch trace (TL) and the shield line (SHL), the guard line (GUL) can prevent the formation of parasitic capacitance between the touch trace (TL) and the shield line (SHL). Since the parasitic capacitance between the touch trace (TL) and the shield line (SHL) is blocked, fluctuations in the signal or voltage state of the shield line (SHL) can prevent them from affecting the touch trace (TL).

[0343] The guard line GUL can be supplied with a signal corresponding to the signal applied to the touch wire TL adjacent to the guard line GUL. The guard line GUL can also be supplied with a signal corresponding to the signal applied to the outermost touch wire TL among multiple touch wire TLs.

[0344] The signal corresponding to the signal applied to the touch wiring TL can mean at least one of the same frequency, amplitude, or phase as the signal applied to the touch wiring TL.

[0345] For example, the guard line GUL can be supplied with the same signal at the same timing as the signal applied to the touch wiring TL, which is set to be the closest to the guard line GUL. No parasitic capacitance can be formed between the touch wiring TL and the guard line GUL. Indirect noise from the shield line SHL can be blocked by the guard line GUL.

[0346] As described above, the shielding wire (SHL) can block external noise from directly affecting the touch wiring TL. Furthermore, the guard wire (GUL) can block indirect noise from the shielding wire (SHL) from affecting the touch wiring TL. The shielding wire (SHL) and guard wire (GUL) can prevent or reduce noise in the signal detected by the touch wiring TL, and can also prevent or reduce signal differences depending on the location of the touch wiring TL.

[0347] At least one of the shielding line SHL or the protection line GUL can be configured to be segmented on the non-display area NA.

[0348] For example, the shielding line SHL and the protective line GUL (such as the portion indicated by 1701) can be set to be divided on the extension of the second boundary BL2.

[0349] The touch electrode lines TEL located on the first sub-region SAA1 and the touch electrode lines TEL located on the third sub-region SAA3 can be configured to be separate from each other and driven independently. The driving timing of the touch wiring TL supplying signals to the touch electrode lines TEL located on each of the first and third sub-regions SAA3 may have slight differences.

[0350] The guard line GUL of the signal supplied and applied to the touch wiring TL can be configured to be divided into sub-regions SAA driven by the corresponding touch wiring TL.

[0351] For example, since the protective line GUL located on each side of the first sub-region SAA1 and the second sub-region SAA2 of the display panel 110 is most adjacent to the touch wiring TL that drives the first sub-region SAA1, it can be set to surround the outside of the first sub-region SAA1.

[0352] Since the protective line GUL located on each side of the third sub-region SAA3 and the fourth sub-region SAA4 of the display panel 110 is closest to the touch wiring TL that drives the third sub-region SAA3, it can be set to surround the outside of the third sub-region SAA3.

[0353] Each protection line GUL located on both sides of the display panel 110 can be supplied with a signal corresponding to the signal applied to the touch wire TL at the timing when the signal is applied to the adjacent touch wire TL.

[0354] In a structure where the touch electrode line TEL set on the display area AA is divided into sub-areas SAA and driven, the noise of the touch wiring TL driving each sub-area SAA can be blocked more accurately.

[0355] The example above illustrates the division of the protection line GUL into four sub-regions SAA, but the protection line GUL can be configured to be divided differently based on the division structure of the sub-regions SAA.

[0356] In addition, the shielding wire SHL, located outside the protection wire GUL, can be configured to be divided in accordance with the division structure of the protection wire GUL.

[0357] For example, the shield line SHL can be configured to be divided along the extension of the second boundary BL2. Alternatively, in some cases, the shield line SHL can be configured not to be divided.

[0358] The grounded shield line SHL can be configured to surround the line located on the non-display area NA and can block external noise. The guard line GUL positioned adjacent to the touch wiring TL can be configured to correspond to the touch wiring TL or the sub-area SAA driven by the touch wiring TL, and can block parasitic capacitance between lines and improve the noise blocking effect.

[0359] At least one of the touch wiring TL, guard line GUL, or shield line SHL located on the non-display area NA can be electrically connected to the pad located on the pad area PA and can be supplied with signals.

[0360] Figure 18 This is a diagram illustrating a specific example of a touch sensor structure of a touch display device 100 according to an embodiment of the present disclosure being implemented on a non-display area NA of a display panel 110, including a pad area PA.

[0361] Reference Figure 18 A pad area PA with multiple pads can be positioned on at least one side of the display panel 110.

[0362] Multiple display pads electrically connected to lines supplying signals for display driving and multiple touch pads TP electrically connected to lines supplying signals for touch sensing can be set on the pad area PA.

[0363] Multiple touch traces TL can extend from the display area AA to the non-display area NA and can pass over the dam DM. The touch traces TL can pass over the dam DM and can be electrically connected to the touch pads TP located on the pad area PA.

[0364] Multiple display signal lines DSL can be configured to extend from the display area AA to the non-display area NA. Since the display signal lines DSL are located below the encapsulation layer ENCAP, they can be configured to pass under the dam DM. The display signal lines DSL can be electrically connected to the display pads located on the pad area PA.

[0365] At least some of the materials constituting the touch electrode TE and touch wiring TL can be used to configure each of the display pads and touch pads TP. At least some of the materials constituting the display signal line DSL can be used to configure each of the display pads and touch pads TP.

[0366] Various pads can be constructed by electrically connecting pad portions made of the material constituting the touch electrode TE and the touch wiring TL on the pad area PA and pad portions made of the material constituting the display signal line DSL.

[0367] Depending on the location of the pad area PA, the planar structure of the displayed pad and touch pad TP settings can vary.

[0368] For example, the pad area PA can be divided into sub-areas SAA corresponding to the display area AA. For example, the pad area PA can include four pad areas PA1, PA2, PA3, and PA4.

[0369] The gating pad GP, which supplies signals or voltages related to the drive of the gating drive circuit 120, the data pad DP, which supplies signals or voltages related to the drive of the data drive circuit 130, and the touch pad TP can be set on the first pad area PA1.

[0370] Touch pads TP located on the first pad area PA1 can be electrically connected to X-touch wiring X-TL that drives X-touch electrode lines X-TEL located on the first sub-area SAA1 and the second sub-area SAA2. In some cases, some touch pads TP located on the first pad area PA1 can be electrically connected to Y-touch wiring Y-TL that drives Y-touch electrode lines Y-TEL located on the first sub-area SAA1 and the second sub-area SAA2.

[0371] At least some touch pads TP located on the first pad area PA1 can be symmetrically arranged with the display pads. For example, touch pads TP can be symmetrically arranged with strobe pads GP. In this case, touch wiring TL connected to touch pads TP can be symmetrically arranged with display signal lines DSL connected to strobe pads GP.

[0372] The data pads DP and touch pads TP, which supply signals or voltages related to the driving of the data drive circuit 130, can be set on the second pad area PA2 and the third pad area PA3.

[0373] Touch pads TP on each of the second pad area PA2 and the third pad area PA3 can be symmetrically arranged. Data pads DP can be arranged between some of the symmetrically arranged touch pads TP.

[0374] The touch pad TP located on the second pad area PA2 can be electrically connected to the Y-touch wiring Y-TL that drives the Y-touch electrode lines Y-TEL located on the first sub-area SAA1 and the second sub-area SAA2. The touch pad TP located on the third pad area PA3 can be electrically connected to the Y-touch wiring Y-TL that drives the Y-touch electrode lines Y-TEL located on the third sub-area SAA3 and the fourth sub-area SAA4.

[0375] In some cases, some touch pads TP located on the second pad area PA2 can be electrically connected to the Y-touch wiring Y-TL that drives the third sub-area SAA3 and the fourth sub-area SAA4. Some touch pads TP located on the third pad area PA3 can be electrically connected to the Y-touch wiring Y-TL that drives the first sub-area SAA1 and the second sub-area SAA2.

[0376] Furthermore, in some cases, some touch pads TP located on the second pad area PA2 can be electrically connected to the X-touch wiring X-TL that drives the X-touch electrode lines X-TEL located on the first sub-area SAA1 and the second sub-area SAA2. Some touch pads TP located on the third pad area PA3 can be electrically connected to the X-touch wiring X-TL that drives the X-touch electrode lines X-TEL located on the third sub-area SAA3 and the fourth sub-area SAA4.

[0377] Touch pads TP, data pads DP, and strobe pads GP can be set on the fourth pad area PA4. Pads set on the fourth pad area PA4 can be symmetrically arranged with the pads set on the first pad area PA1.

[0378] Touch pads TP located on the fourth pad area PA4 can be electrically connected to the X touch wiring X-TL that drives the X touch electrode lines X-TEL located on the third sub-area SAA3 and the fourth sub-area SAA4. In some cases, some touch pads TP located on the fourth pad area PA4 can be electrically connected to the Y touch wiring Y-TL that drives the Y touch electrode lines Y-TEL located on the third sub-area SAA3 and the fourth sub-area SAA4.

[0379] With the gating drive circuit 120 located on both sides of the display panel 110, the gating pad GP can be located on the first pad area PA1 and the fourth pad area PA4.

[0380] Data pads DP and touch pads TP can be configured to be distributed on various areas inside the gating pad GP and can be configured to be electrically connected to the data line DL or touch line TL located on the display area AA.

[0381] In addition to the examples above, the pads set on the pad area PA can be configured in various ways for effective connection to the display signal line DSL and the touch wiring TL.
