[0102] The present application provides an array substrate and a manufacturing method thereof, a display panel and a manufacturing method thereof, and the following will be combined with the accompanying drawings Figures 1 to 17 Various embodiments of a display panel and a display device are described.

[0103] Figure 1 This is a schematic diagram of the structure of an embodiment of an array substrate provided in this application. Figure 1As shown, the array substrate 1000 includes a substrate 110 and a patterned first conductive layer 200 disposed on one side of the substrate 110 .

[0104] For further information, see Figure 2 , Figure 2 This is a schematic diagram of the structure of the first conductive layer provided in this application. Figure 2 As shown, the first conductive layer 200 includes a plurality of data signal lines data, touch signal lines TP and fixed voltage signal lines Vref extending along the second direction and arranged along the first direction. The fixed voltage signal lines Vref are arranged between the data signal lines data and the touch signal lines TP. The first direction X intersects with the second direction Y, and can be arranged vertically, which is not limited here.

[0105] In this embodiment, the fixed voltage signal line Vref is located between the adjacent data signal line data and the touch signal line TP, and is used to form a signal shield between the data signal line data and the touch signal line TP, thereby effectively avoiding signal crosstalk between the data signal line data and the touch signal line TP, and improving the display and touch performances, respectively. For details, please refer to Figure 2 The dotted line frame shows the location of the fixed voltage signal line Vref. The fixed voltage signal line Vref is arranged between two adjacent data signal lines data and the touch signal line TP.

[0106] It should be noted that the signal on the fixed voltage signal line Vref is a fixed, non-jumping signal, and the fixed voltage signal line Vref can effectively shield the signal interference between the data signal line data and the touch signal line TP. The fixed voltage signal line Vref can be a reference signal line or a zero potential signal line, which is not limited here.

[0107] The first conductive layer 200 includes signal lines such as a first data signal line data1, a second data signal line data2, a third data signal line data3, a first high signal line VDD1, a second high signal line VDD2, a touch line TP, and a reference line Vref, etc. The signal lines are repeatedly arranged along the arrangement direction of the pixel units.

[0108] Among them, the first data signal line data1, the second data signal line data2 and the third data signal line data3 provide data signals for the first sub-pixel, the second sub-pixel and the third sub-pixel in each pixel unit 30 respectively, so that each sub-pixel in the pixel unit 30 emits light of different gray levels, which is not limited here.

[0109] like Figure 2As shown, the first conductive layer 200 includes a plurality of power supply voltage signal lines VDD extending along the second direction and arranged along the first direction. In a repeating unit, the power supply voltage signal line VDD includes a first power supply voltage signal line VDD1 and a second power supply voltage signal line VDD2; and / or, the data signal line data includes a first data signal line data1, a second data signal line data2 and a third data signal line data3; and / or, the touch signal line TP includes a first touch signal line TP1 and a second touch signal line TP2.

[0110] The first data signal line data1 and the second data signal line data2 are located between the first power supply voltage signal line VDD1 and the second power supply voltage signal line VDD2. The first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2 and the second power supply voltage signal line VDD2 are arranged in sequence along the first direction.

[0111] Specifically, Figure 2 The first high potential signal line VDD1 and the second high potential signal line VDD2 in the left pixel unit are used as references.

[0112] The first touch signal line TP1, the fixed voltage signal line Vref, and the third data signal line data3 are sequentially arranged on the side of the first power supply voltage signal line VDD1 away from the second power supply voltage signal line VDD2. Preferably, the first touch signal line TP1 is located between the fixed voltage signal line Vref and the first power supply voltage signal line VDD1. The third data signal line data3 is a data signal line in the previous pixel unit, which is not limited here.

[0113] And / or, a third data signal line data3, a fixed voltage signal line Vref, and a second touch signal line TP2 are sequentially arranged on the side of the second power supply voltage signal line VDD2 away from the first power supply voltage signal line VDD1. Preferably, the third data signal line data3 is located between the fixed voltage signal line Vref and the second power supply voltage signal line VDD2.

[0114] Further, Figure 2 The first high potential signal line VDD1 and the second high potential signal line VDD2 in the pixel unit on the right are used as references.

[0115] A second touch signal line TP2, a fixed voltage signal line Vref, and a third data signal line data3 are sequentially arranged on the side of the first power voltage signal line VDD1 away from the second power voltage signal line VDD2. Preferably, the second touch signal line TP2 is located between the fixed voltage signal line Vref and the first power voltage signal line VDD1. The third data signal line data3 is a data signal line in the left pixel unit, which is not limited here.

[0116] And / or, a third data signal line data3, a fixed voltage signal line Vref, and a first touch signal line TP1 are sequentially arranged on a side of the second power supply voltage signal line VDD2 away from the first power supply voltage signal line VDD1. Preferably, the third data signal line data3 is located between the fixed voltage signal line Vref and the second power supply voltage signal line VDD2.

[0117] The above-mentioned repeating units are used for repeated wiring, which will not be described in detail here.

[0118] In this embodiment, compared with the solution in the prior art that a power supply voltage signal line VDD is arranged on the same side of each data signal line data (that is, a power supply voltage signal line VDD is arranged between each two adjacent data signal lines data), the present application arranges the first data signal line data1 and the second data signal line data2 adjacent to each other, moves the power supply voltage signal line VDD between the first data signal line data1 and the second data signal line data2 to the right side of the second data signal line data2, and merges the power supply voltage signal line VDD adjacent to the third data signal line data3 into one power supply voltage signal line, thereby reducing the number of power supply voltage signal lines in each pixel unit. At the same time, it is convenient to arrange the touch signal line and the fixed voltage signal line between the two pixel units.

[0119] Further, each pixel unit is described as a repeating unit, please refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the structure of an embodiment of a first conductive layer in a pixel unit of the present application. Figure 3 As shown, each pixel unit 30 further includes a first touch signal line TP1 and / or a second touch signal line TP2, wherein the first touch signal line TP1 is arranged on a side of the first power voltage signal line VDD1 away from the first data signal line data1, and / or the second touch signal line TP2 is arranged on a side of the third data signal line data3 away from the second power voltage signal line VDD2. The touch signal in the pixel unit 30 can be transmitted by the first touch signal line TP1 located on a side of the first power voltage signal line VDD1 away from the first data signal line data1; or by the second touch signal line TP2 located on a side of the third data signal line data3 away from the second power voltage signal line VDD2, that is, the touch signal line TP and the fixed voltage signal line Vref are both located between two adjacent pixel units 30, and the pixel unit 30 can transmit the touch signal by the touch signal line TP located on its left side, or by the touch signal line TP located on its right side, which is not specifically limited here.

[0120] Furthermore, each pixel unit 30 also includes a fixed voltage signal line Vref, wherein the fixed voltage signal line Vref includes a line disposed on a side of the touch signal line TP away from the first power supply voltage signal line VDD1, and a line disposed on a side of the third data signal line data3 away from the second power supply voltage signal line VDD, and located between the third data signal line data3 and the touch signal line TP. The fixed voltage signal line Vref disposed between the third data signal line data3 and the touch signal line TP can isolate the third data signal line data3 from the touch signal line TP, and avoid signal crosstalk between the third data signal line data3 and the touch signal line TP. That is, the fixed voltage signal line Vref is also located between two adjacent pixel units 30, and is disposed between the third data signal line data3 and the touch signal line TP.

[0121] It should be noted that the first data signal line data1, the second data signal line data2, the third data signal line data3, the first power supply voltage signal line VDD1, the second power supply voltage signal line VDD2, the touch signal line TP, and the fixed voltage signal line Vref are arranged in parallel and at intervals along the second direction Y, so that each signal is transmitted independently, but if two adjacent signal lines transmit different signals, they may interfere with each other. In particular, in the In cell touch architecture, the touch signal line TP is arranged in the thin film encapsulation layer and is easily affected by the data signal on the adjacent data signal line. Therefore, according to the arrangement of the first data signal line data1, the second data signal line data2, the third data signal line data3, the first power supply voltage signal line VDD1, the second power supply voltage signal line VDD2, the touch signal line TP, and the fixed voltage signal line Vref in the first conductive layer 200 of the present case, the electrical signal interference between the display signal and the touch signal can be effectively reduced, and the display and touch performance can be improved.

Fig. 9 As shown, since the metal layers of the first pixel circuit structure 121 and the metal layers of the second pixel circuit structure 122 located below the first conductive layer 200 are symmetrically arranged, the first pixel circuit structure 121 and the second pixel circuit structure 122 are symmetrically arranged along the second direction Y. Similarly, since the metal layers forming the third pixel circuit structure 123 are arranged in the same manner as the metal layers of the first pixel circuit structure 121 and are symmetrically arranged along the second direction Y with the metal layers of the second pixel circuit structure 122, the third pixel circuit structure 123 is arranged in the same manner as the first pixel circuit structure 121 and is symmetrically arranged along the second direction Y with the second pixel circuit structure 122.

In other words, the orthographic projection of the first power supply voltage signal line VDD1 on the substrate 110 at least partially covers the first pixel circuit structure 121. Furthermore, the orthographic projection of the second power supply voltage signal line VDD2 on the substrate 110 at least partially covers the orthographic projection of the second pixel circuit structure 122 on the substrate 110 and the orthographic projection of the third pixel circuit structure 123 on the substrate 110.

For details, please refer to Fig.11 , Fig.11 Schematic diagram of the structure of an embodiment of the anode layer of the present application. Fig.11 As shown, the anode layer 310 includes a first anode 301, a second anode 302 and a third anode 303. The region of each pixel unit 30 includes the first anode 301, the second anode 302 and the third anode 303 arranged at intervals. It can be understood that the first anode 301, the second anode 302 and the third anode 303 are the light-emitting regions of the first sub-pixel, the second sub-pixel and the third sub-pixel respectively.

[0143] Preferably, the first anode 301 and the second anode 302 are arranged along the second direction Y, and the third anode 303 and the first anode 301 and the second anode 302 are arranged along the first direction X. Preferably, the upper edge of the third sub-pixel is aligned with the upper edge of the first sub-pixel, and the lower edge is aligned with the lower edge of the second sub-pixel, so that each pixel unit can be arranged in a regular shape.

[0144] Preferably, in the direction of the orthographic projection plane perpendicular to the substrate, the orthographic projections of the first anode 301 and the second anode 302 on the substrate 110 sequentially cover the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, and the second power supply voltage signal line VDD2. In other words, the orthographic projection of the first anode 301 on the substrate 110 overlaps with the orthographic projections of the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, and the second power supply voltage signal line VDD2 on the substrate 110; the orthographic projection of the second anode 302 on the substrate 110 overlaps with the orthographic projections of the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, and the second power supply voltage signal line VDD2 on the substrate 110. Preferably, in the direction along the orthographic projection plane perpendicular to the substrate, the third anode 303 is entirely projected onto the second power supply voltage signal line VDD2, wherein the area of ​​the second power supply voltage signal line VDD2 projected onto the substrate 110 is larger than the area of ​​the third anode 303 projected onto the substrate 110, that is, the orthographic projection of the second power supply voltage signal line VDD2 on the substrate 110 covers the orthographic projection of the third anode 303 on the substrate 110.

[0145] Preferably, on the orthographic projection plane perpendicular to the substrate, the overlapping area between the first anode 301 and the first power supply voltage signal line VDD1 is equal to the overlapping area between the first anode 301 and the second power supply voltage signal line VDD2; the overlapping area between the second anode 302 and the first power supply voltage signal line VDD1 is equal to the overlapping area between the second anode 302 and the second power supply voltage signal line VDD2. That is, the overlapping area of ​​the orthographic projection of the first anode 301 on the substrate and the orthographic projection of the first power supply voltage signal line VDD1 on the substrate (which can be defined as the first overlapping area) and the overlapping area of ​​the orthographic projection of the first anode 301 on the substrate and the orthographic projection of the second power supply voltage signal line VDD2 on the substrate (which can be defined as the second overlapping area) are equal; the overlapping area of ​​the orthographic projection of the second anode 302 on the substrate and the orthographic projection of the first power supply voltage signal line VDD1 on the substrate (which can be defined as the third overlapping area) and the overlapping area of ​​the orthographic projection of the second anode 302 on the substrate and the orthographic projection of the second power supply voltage signal line VDD2 on the substrate (which can be defined as the fourth overlapping area) are equal. Thereby, the first anode 301 is symmetrically arranged along the second direction Y based on the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2 and the second power supply voltage signal line VDD2 of the first conductive layer 200; the second anode 302 is also symmetrically arranged along the second direction Y based on the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2 and the second power supply voltage signal line VDD2 of the first conductive layer 200, thereby improving the display effect of the first sub-pixel and the second sub-pixel and improving color deviation.

[0146] Furthermore, the orthographic projection of the third anode 303 on the substrate 110 is completely located within the orthographic projection of the second power supply voltage signal line VDD2 of the first conductive layer 200 on the substrate 110, which effectively improves display abnormality.

[0147] Preferably, the symmetry axis of the orthographic projection of the first anode 301 on the substrate 110 along the second direction Y coincides with the symmetry axis of the orthographic projection of the second anode 302 on the substrate along the second direction Y. This further improves the color deviation of the first sub-pixel and the second sub-pixel when the display is melted.

[0148] Preferably, the symmetry axis of the orthographic projection of the first anode 301 on the substrate 110 along the second direction Y, the symmetry axis of the orthographic projection of the second anode 302 on the substrate 110 along the second direction Y, and the symmetry axis between the orthographic projection of the first data signal line data1 on the substrate 110 and the orthographic projection of the second data signal line data2 on the substrate 110 coincide with each other. It should be noted that the orthographic projection of the first data signal line data1 on the substrate 110 and the orthographic projection of the second data signal line data2 on the substrate 110 are symmetrical along the second direction Y, and their symmetry axes are located between the first data signal line data1 and the second data signal line data2. That is to say, in the top view projection plane (or perpendicular to the orthographic projection plane), the symmetry axis of the first anode 301, the symmetry axis of the second anode 302, and the symmetry axis between the first data signal line data1 and the second data signal line data2 coincide with each other (three axes coincide with each other).

[0149] Furthermore, the first anode 301 is electrically connected to the first pixel circuit structure 121 located below the first conductive layer 200, the second anode 302 is electrically connected to the second pixel circuit structure 122 located below the first conductive layer 200, and the third anode 303 is electrically connected to the third pixel circuit structure 123 located below the first conductive layer 200.

[0150] Furthermore, the anode layer 310 further includes a first anode wiring 311 connected to the first anode 301, a second anode wiring 312 connected to the second anode 302, and a third anode wiring 313 connected to the third anode 303. Fig.12 , Fig.12 It is a structural schematic diagram of a specific embodiment of the anode layer of the present application.

[0151] Preferably, the first anode wiring 311 is projected on the first power supply voltage signal line VDD1, and is electrically connected to the first pixel circuit structure 121 located below the first power supply voltage signal line VDD1 through a first via hole. Preferably, the positive projection of the first anode 301 on the substrate 110 sequentially covers the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, and the second power supply voltage signal line VDD2. And the area of ​​the first anode 301 projected on the first power supply voltage signal line VDD1 is equal to the area projected on the second power supply voltage signal line VDD2.

[0152] Preferably, the second anode wiring 312 is projected on the second power supply voltage signal line VDD2, and is electrically connected to the second pixel circuit structure 122 located below the second power supply voltage signal line VDD2 through a second via hole. Preferably, the positive projection of the second anode 302 on the substrate 110 sequentially covers the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, and the second power supply voltage signal line VDD2. And the area of ​​the second anode 302 projected on the first power supply voltage signal line VDD1 is equal to the area projected on the second power supply voltage signal line VDD2.

[0153] Preferably, along the projection plane direction perpendicular to the substrate, the third anode wiring 313 is projected on the second power supply voltage signal line VDD2, and is electrically connected to the third pixel circuit structure 123 located below the second power supply voltage signal line VDD2 through a third via hole. Preferably, the orthographic projection of the second power supply voltage signal line VDD2 on the substrate 110 covers the orthographic projection of the third anode 303 on the substrate 110.

[0154] Preferably, the materials of the first anode wiring 311 , the second anode wiring 312 and the third anode wiring 313 may be the same as or different from those of the first anode 301 , the second anode 302 and the third anode 303 , which is not limited herein.

[0155] Further, the first via hole, the second via hole, and the third via hole are arranged along the first direction X and are located on the same straight line. This is because the first pixel circuit structure 121, the second pixel circuit structure 122, and the third pixel circuit structure 123 are arranged along the first direction X and are symmetrical along the second direction Y, so that each via hole is also at a corresponding (symmetrical) position in each pixel circuit structure, that is, each via hole is also symmetrically arranged in the second direction Y. Preferably, the first via hole, the second via hole, and the third via hole are located in the non-luminous area of ​​the pixel unit.

[0156] Preferably, the width of the second power supply voltage signal line VDD2 is greater than the width of the first power supply voltage signal line VDD1.

[0157] In this embodiment, the touch signal line is placed after the occupied space of the pixel circuit structure is compressed, so that the touch signal line TP is located between two pixel units, and the data signal line and the touch signal line between two adjacent pixel units are isolated by a fixed voltage signal line Vref, thereby effectively avoiding crosstalk between the data signal line and the touch signal line. Compressing the space of the pixel circuit structure refers to reducing the occupied space of the pixel circuit structure on the substrate plane (that is, the projection plane).

[0158] Furthermore, in the same pixel unit, the first pixel circuit structure and the second pixel circuit structure are designed symmetrically along the Y axis, and the light-emitting areas of the first sub-pixel and the second sub-pixel are symmetrically arranged based on the first pixel circuit structure and the second pixel circuit structure or symmetrically arranged along the Y axis, which can improve the display quality and improve the color deviation. In the same pixel unit, the third pixel circuit structure and the second pixel circuit structure are designed symmetrically along the Y axis, which is consistent with the design of the first pixel circuit structure, and the light-emitting area of ​​the third sub-pixel is symmetrically arranged based on the third pixel circuit structure or symmetrically arranged along the Y axis, which can further improve the display quality and improve the color deviation.

The array substrate 1000 is the array substrate described in any of the above embodiments.

[0160] The pixel unit layer 300 includes a plurality of pixel units arranged in an array, each pixel unit including a first sub-pixel, a second sub-pixel and a third sub-pixel (not shown in the figure). The first sub-pixel corresponds to the first anode 301, the second sub-pixel corresponds to the second anode 302, and the third sub-pixel corresponds to the third anode. It can be understood that the first sub-pixel includes the first anode 301, the first light-emitting layer, the first cathode and the encapsulation layer stacked in sequence; the second sub-pixel includes the second anode 302, the second light-emitting layer and the second cathode and the encapsulation layer stacked in sequence; the third sub-pixel includes the third anode 303, the third light-emitting layer and the third cathode and the encapsulation layer stacked in sequence, which are not specifically limited here.

[0161] Please refer to Fig.14 , Fig.14 It is a schematic diagram of a top view structure of an embodiment of a display panel of the present application, specifically including a schematic diagram of a top view structure of a pixel unit layer in the display panel.

[0162] The pixel unit layer 300 further includes a pixel definition layer PDL, which covers a portion of the surface of the anode layer 310 and exposes a portion of the surface of the anode layer 310 to form a first anode 301, a second anode 302, and a third anode 303. The first anode 301 is a light-emitting area of ​​a first sub-pixel, the second anode 302 is a light-emitting area of ​​a second sub-pixel, and the third anode 303 is a light-emitting area of ​​a third sub-pixel.

[0163] Preferably, the first anode 301 and the second anode 302 are arranged in parallel and spaced apart along the second direction, and the third anode 303 is arranged in parallel and spaced apart along the first direction with the first anode 301 and the second anode 302 .

[0164] Preferably, the second anode 302 is arranged in alignment with the first anode 301 in the second direction Y, and the third anode 303 is arranged in alignment with the first anode 301 and the second anode 302 in the first direction X. Specifically, the upper edge of the third anode 303 is aligned with the upper edge of the first anode 301, and the lower edge is aligned with the lower edge of the second anode 302, so that each pixel unit can be arranged in a regular shape.

[0165] like Fig.14 As shown, on the vertical projection plane in the stacking direction, the first anode 301 and the second anode 302 are projected on the first data signal line data1, the second data signal line data2, and part of the first power supply voltage signal line VDD1 and part of the second power supply voltage signal line VDD2. The third anode 303 is fully projected on the second power supply voltage signal line VDD2.

[0166] Preferably, the projection area of ​​the first anode 301 and the second anode 302 projected on the first power supply voltage signal line VDD1 is symmetrical with the projection area projected on the second power supply voltage signal line VDD2 along the second direction Y. That is to say, the projection area of ​​the first anode 301 projected on the first power supply voltage signal line VDD1 is the same as the projection area projected on the second power supply voltage signal line VDD2, and the projection area of ​​the second anode 302 projected on the first power supply voltage signal line VDD1 is the same as the projection area projected on the second power supply voltage signal line VDD2. Moreover, the widths of the first data signal line data1 and the second data signal line data2 are also set in the same way, so that the light emission center of the first anode 301 and the second anode 302 can be located between the first data signal line data1 and the second data signal line data2. In addition, the first anode 301 and the second anode 302 are symmetrically arranged along the second direction Y, which can improve the display quality and improve the display color deviation.

[0167] In this embodiment, the third anode 303 is entirely located on the second power supply voltage signal line VDD2. Therefore, the third anode 303 is also symmetrically arranged based on the second power supply voltage signal line VDD2 or symmetrically arranged along the Y axis, thereby improving the display quality of the third sub-pixel and improving the display color deviation.

[0168] In this embodiment, preferably, the width of the second power supply voltage signal line VDD2 in the first direction X is greater than the width of the first power supply voltage signal line VDD1 in the first direction X. Thus, the third anode 303 and part of the first anode 301 and the second anode 302 can be projected onto the second power supply voltage signal line VDD2.

[0169] Preferably, the first sub-pixel is a red sub-pixel R, the second sub-pixel is a green sub-pixel G, and the third sub-pixel is a blue sub-pixel B.

[0170] See also Fig.15 , Fig.15 This is a schematic diagram of a top view of an embodiment of the second conductive layer provided in this application. Fig.15 As shown, the pixel unit layer 300 includes a pixel definition layer PDL, and a second conductive layer 320 arranged on a side of the pixel definition layer PDL away from the anode layer 310. The second conductive layer 320 includes a first partition structure TP-s and a second partition structure VSS.

[0172] Preferably, the first partition structure TP-s and the second partition structure VSS have the same cross-sectional shape, such as Fig.13 In other embodiments, the configuration may be different and is not limited here.

[0173] The first partition structure TP-s includes a first touch electrode TP-s1 arranged along a first direction X and a second touch electrode TP-s2 arranged along a second direction Y. The first touch electrode TP-s1 and the second touch electrode TP-s2 are electrically connected to each other to form a touch electrode block whose touch range covers (or encompasses) a plurality of pixel units.

[0174] Preferably, the orthographic projection of the second touch electrode TP-s2 on the substrate at least covers a portion of the orthographic projection of the touch signal line TP on the substrate, that is, the orthographic projection of the second touch electrode TP-s2 on the substrate at least partially overlaps with the orthographic projection of the touch signal line TP on the substrate. Thus, the second touch electrode TP-s2 located in the second conductive layer 320 and the touch signal line TP located in the first conductive layer 200 can be connected to the touch signal through the vertical via hole for transmitting the touch signal.

[0175] Preferably, the orthographic projection of the second touch electrode TP-s2 on the substrate can also extend in the direction of the orthographic projection of the fixed voltage signal line Vref and the power voltage signal line VDD adjacent to the touch signal line TP on the substrate, and partially overlap with the orthographic projection of the fixed voltage signal line Vref and the power voltage signal line VDD on the substrate, that is, the second touch electrode TP-s2 can extend along the first direction X, thereby expanding the width of the second touch electrode TP-s2 in the first direction X, and also expanding the touch coverage of the first partition structure TP-s. It should be noted that, in order to further avoid signal crosstalk between the data signal line data and the touch signal line TP, preferably, the orthographic projection of the second touch electrode TP-s2 on the substrate does not overlap with the orthographic projection of the data signal line data on the substrate.

[0176] Preferably, the orthographic projection of the first touch electrode TP-s1 on the substrate 110 overlaps with the orthographic projections of the first power supply voltage signal line VDD1, the first data signal line data1, the second data signal line data2, the second power supply voltage signal line VDD2, the third data signal line data3 and the fixed voltage signal line Vref on the substrate 110 in sequence. Compared with the prior art, the first touch electrode TP-s1 only needs to cross two power supply voltage signal lines, while in the prior art, the first touch electrode TP-s1 needs to cross three power supply voltage signal lines.

[0177] The second partition structure VSS is also disposed on the surface of the pixel definition layer PDL away from the anode layer 310 . The second partition structure VSS includes a first cathode voltage signal line VSS1 and a second cathode voltage signal line VSS2 .

[0178] Preferably, the first partition structure TP-s is arranged on the surface of the pixel definition layer PDL, and is located in the same layer as the second partition structure VSS and is arranged at intervals. The first partition structure TP-s is arranged on the side of the second partition structure VSS away from the pixel unit. The pixel unit includes a first sub-pixel, a second sub-pixel and a third sub-pixel, that is, arranged around the outer periphery of the pixel unit.
