Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] OLED (Organic Light-Emitting Diode) is a self-emissive display technology with advantages such as self-emissiveness, wide viewing angle, fast response, low power consumption, and high contrast.

[0003] In existing technologies, some metal traces in OLED display panels have light leakage issues, which affect the display effect of the display panel. Summary of the Invention

[0004] This invention provides a display panel and display device to avoid exposing the touch metal traces and ensure the display effect of the display panel.

[0005] In a first aspect, the present invention provides a display panel, including a display area and a plurality of touch electrodes and a plurality of light-emitting elements located in the display area; The touch electrode includes an electrode grid line. The electrode grid line in the same touch electrode includes multiple first electrode grid lines and multiple second electrode grid lines. The first electrode grid lines extend along a first direction and the multiple first electrode grid lines are arranged along a second direction. The second electrode grid lines extend along the second direction and connect two adjacent first electrode grid lines. The first electrode grid line and the second electrode grid line intersect to define a plurality of electrode grid holes; The plurality of electrode mesh holes include a first electrode mesh hole and a second electrode mesh hole. Along a third direction, the first electrode mesh hole overlaps with the light-emitting element, while the second electrode mesh hole does not overlap with the light-emitting element; the third direction is the thickness direction of the display panel.

[0006] In a second aspect, the present invention provides a display device comprising the display panel described in any one of the first aspects.

[0007] The technical solution of this invention involves a display panel with multiple touch electrodes and multiple light-emitting elements disposed within its display area. Each touch electrode contains multiple first electrode grid lines and multiple second electrode grid lines. The first and second electrode grid lines intersect to define first and second electrode grid holes. Along a third direction, the first electrode grid holes overlap with the light-emitting elements, while the second electrode grid holes do not overlap with them. The placement of light-emitting elements within the first electrode grid holes ensures the normal display function of the display panel. No light-emitting elements are placed within the second electrode grid holes, thus providing sufficient space within these holes to accommodate a light-shielding structure that blocks light leakage from the touch electrode grid lines, thereby ensuring the display effect of the display panel.

Detailed Implementation

[0011] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0012] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0013] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a touch electrode provided in an embodiment of the present invention. Figure 3 This is a partially enlarged structural diagram of a touch electrode provided in an embodiment of the present invention. Figure 4 This is a partially enlarged structural diagram of another touch electrode provided in an embodiment of the present invention, as shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the display panel includes a display area 101 and multiple touch electrodes 102 and multiple light-emitting elements 103 located in the display area 101; the touch electrodes 102 include electrode grid lines 104, and the electrode grid lines 104 in the same touch electrode 102 include multiple first electrode grid lines 1041 and multiple second electrode grid lines 1042. The first electrode grid lines 1041 extend along a first direction X1 and the multiple first electrode grid lines 1041 are arranged along a second direction X2, and the second electrode grid lines 1042 are arranged along a second direction X2. The first electrode grid lines 1041 extend in two directions X2 and connect adjacent first electrode grid lines 1041; the first electrode grid lines 1041 and second electrode grid lines 1042 intersect to define a plurality of electrode grid holes 105; the plurality of electrode grid holes 105 include first electrode grid holes 1051 and second electrode grid holes 1052, and along a third direction X3, the first electrode grid holes 1051 overlap with the light-emitting element 103, while the second electrode grid holes 1052 do not overlap with the light-emitting element 103; the third direction X3 is the thickness direction of the display panel.

[0014] The display panel includes multiple light-emitting elements 103 located in the display area 101. The light-emitting elements 103 may include red, green, and blue light-emitting elements to achieve color display. The light-emitting elements 103 can be organic light-emitting diodes (OLEDs). Each light-emitting element may include a first electrode, a second electrode, and an organic common layer located between the first and second electrodes. The organic common layer may include, but is not limited to, a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron transport layer, a hole blocking layer, and an electron injection layer. Alternatively, the organic common layer may also include a charge-generating layer, such as a P-type charge-generating layer and an N-type charge-generating layer. When a voltage is applied to the first and second electrodes of the organic light-emitting diode, holes passing through the hole transport layer and electrons passing through the electron transport layer move to the light-emitting layer to form excitons, causing visible light to be emitted from the light-emitting layer.

[0015] Furthermore, the display panel provided in this application embodiment can be a touch display panel, such as... Figures 1 to 4As shown, a touch electrode 102 is provided in the display area AA. The touch electrode 102 receives touch driving signals and feeds back touch sensing signals to the touch driving chip (not shown in the figure). The touch driving chip determines the touch position and / or touch pressure based on the received touch sensing signals, thereby realizing the touch function of the display panel. Specifically, multiple touch electrodes 102 may include touch driving electrodes 1021 and touch sensing electrodes 1022. The touch driving electrodes 1021 and touch sensing electrodes 1022 may be located on the same metal layer. Different touch electrodes can be connected by a bridge connection. Furthermore, the bridge connection between the touch driving electrodes 1021 and the touch sensing electrodes 1022 can be arranged in different layers to ensure that the touch electrodes 102 are independent of each other. In this embodiment, the touch electrode can be a grid-shaped touch electrode, that is, each touch electrode 102 includes an electrode grid line 104, and the light-emitting element 103 can be disposed in the electrode grid hole defined by the electrode grid line 104, which can avoid the setting of the touch electrode from affecting the normal light emission of the light-emitting element.

[0016] For details, please refer to Figure 3 and Figure 4 As shown, each touch electrode 102 includes multiple first electrode grid lines 1041 and multiple second electrode grid lines 1042. The first electrode grid lines 1041 extend along a first direction X1, and the multiple first electrode grid lines 1041 are arranged along a second direction X2. The second electrode grid lines 1042 extend along the second direction X2 and connect adjacent first electrode grid lines 1041, such that the first electrode grid lines 1041 and second electrode grid lines 1042 intersect each other, thereby forming multiple electrode grid holes 105. Setting the touch electrode 102 as a metal grid structure can avoid affecting the normal light emission and display of the light-emitting element 103.

[0017] Multiple electrode grid holes 105 include a first electrode grid hole 1051 and a second electrode grid hole 1052. Along a third direction X3, the first electrode grid hole 1051 overlaps with the light-emitting element 103, allowing light emitted from the light-emitting element 103 to pass through the first electrode grid hole 1051 without obstruction, preventing the first electrode grid lines 1041 and 1042 from blocking the light and ensuring the brightness of the display panel. Along a third direction X3, the second electrode grid hole 1052 does not overlap with the light-emitting element 103; that is, no light-emitting element 103 is placed in the area defined by the second electrode grid hole 1052. This ensures that there is sufficient space within the second electrode grid hole 1052 to arrange light-shielding parts to block the touch electrode grid lines. This also ensures that different first electrode grid lines 1041 can be interconnected through the second electrode grid lines 1042 to form a complete grid-like touch electrode. Furthermore, the second electrode grid line 1042 and the light-shielding part are arranged with sufficient spacing between adjacent light-emitting units, thereby ensuring that the light-shielding part located between adjacent light-emitting elements 103 in the display panel can effectively block the electrode grid line 104, avoiding the problem of metal reflection light caused by the exposure of the electrode grid line 104, and ensuring the display effect of the display panel.

[0018] It should be noted that, as Figure 3 and Figure 4 As shown, the extension of the first electrode grid line 1041 along the first direction X1 can be understood as the general extension direction of the first electrode grid line 1041 being the first direction X1, or the overall extension direction of the first electrode grid line 1041 being the first direction X1. It can also be understood as the projected length of the first electrode grid line 1041 in the first direction X1 being greater than its projected length in other directions. Limiting the extension of the first electrode grid line 1041 along the first direction X1 does not mean that any small segment of the first grid line 1041 extends along the first direction X1. Similarly, the extension of the second electrode grid line 1042 along the second direction X2 can be understood as the general extension direction of the second electrode grid line 1042 being the second direction X2, or the overall extension direction of the second electrode grid line 1042 being the second direction X2. It can also be understood as the projected length of the second electrode grid line 1042 in the second direction X2 being greater than its projected length in other directions. Limiting the extension of the second electrode grid line 1042 along the second direction X2 does not mean that any small segment of the second grid line 1042 extends along the second direction X2.

[0019] In this embodiment of the invention, the touch electrodes are arranged as an electrode grid, with the grid lines intersecting to form a first electrode grid hole and a second electrode grid hole. Along a third direction, the first electrode grid hole overlaps with the light-emitting element, while the second electrode grid hole does not overlap with the light-emitting element. The light-emitting element is placed in the first electrode grid hole to ensure the normal display function of the display panel. No light-emitting element is placed in the second electrode grid hole, thus providing sufficient space within the second electrode grid hole to accommodate a light-shielding portion to block the touch electrode grid lines. This avoids the problem of insufficient light-emitting element spacing between adjacent light-emitting elements, ensuring the display panel's display effect.

[0020] Optional, Figure 5 for Figure 4 A schematic diagram of a cross-sectional structure along section line AA', as shown below. Figure 3 , Figure 4 He Ru Figure 5 As shown, the display panel also includes a color resist structure 106 located on the light-emitting side of the light-emitting element 103; the color resist structure 106 includes a light-transmitting part 1061 and a light-shielding part 1062. Along the third direction X3, the light-transmitting part 1061 overlaps with the light-emitting element 103, and the light-shielding part 1062 overlaps with the gap between two adjacent light-emitting elements 103, the electrode grid line 104, and the second electrode grid hole 1052.

[0021] Along the third direction X3, a color resist structure 106 is also provided on the side of the touch electrode 102 away from the light-emitting element 103. The color resist structure 106 includes a light-transmitting part 1061 and a light-shielding part 1062. The light-transmitting part 1061 overlaps with the light-emitting element 103, allowing light emitted from the light-emitting element 103 to pass through, thereby improving the color purity of the light emitted from the light-emitting element 103 and ensuring the light-emitting effect. A light-shielding part 1062 is also provided between adjacent color resist structures 106. Along the third direction X3, the light-shielding structure overlaps with the gap between two adjacent light-emitting elements 103, the electrode grid line 104, and the second electrode grid hole 1052, so that the light-shielding part 1062 can block non-light-emitting areas and prevent metallic reflection light. For example, Figure 4 As shown, the light-shielding part 1062 can be a black matrix.

[0022] Optional, Figure 6 for Figure 4 A schematic diagram of a cross-sectional structure along section line AA', as shown below. Figure 6 As shown, the light-transmitting part 1061 includes a color resist layer 107, and the light-shielding part 1062 includes at least two color resist layers 107 stacked along the third direction X3.

[0023] The light-transmitting portion 1061 includes a color resist layer 107, and the light-shielding portion 1062 includes at least two color resist layers 107 stacked along a third direction X3. For example, when the light-shielding portion 1062 includes two color resist layers 107 stacked along a third direction X3, the color of the color resist layer 107 corresponding to the light-transmitting portion 1061 is the same as the color of one of the at least two color resist layers 107 in the light-shielding portion 1062, while the other color is different. Similarly, when the light-shielding portion 1062 includes two color resist layers 107 stacked along a third direction X3, the color of the color resist layer 107 corresponding to the light-transmitting portion 1061 is the same as the color of one of the at least two color resist layers 107 in the light-shielding portion 1062, while the other two color resist layers are different. This allows the light-shielding portion 1062 to absorb large-angle light and prevent light crosstalk between different light-emitting elements 103.

[0024] For example, when the light-emitting element 103 includes a red light-emitting element, a green light-emitting element, and a blue light-emitting element, the light-transmitting portion 1061 corresponding to the red light-emitting element is a red color resist layer 1072, the light-transmitting portion 1061 corresponding to the green light-emitting element is a green color resist layer 1071, and the light-transmitting portion 1061 corresponding to the blue light-emitting element is a blue color resist layer 1073. The light-shielding portion 1062 includes a red color resist layer 1071, a blue color resist layer 1073, and a green color resist layer 1072 stacked sequentially. The light emitted by the red light-emitting element... Large-angle red light can be absorbed by blue color resist layer 1073 and green color resist layer 1072. Large-angle green light emitted by green light-emitting element can be absorbed by red color resist layer 1071 and blue color resist layer 1073. Large-angle blue light emitted by blue light-emitting element can be absorbed by red light-emitting element and green light-emitting element. This avoids light crosstalk between different light-emitting elements 103 and can also achieve light blocking using the existing color resist structure 106 without adding a mask or additional black matrix material, thus reducing the difficulty of the fabrication process.

[0025] Optional, continue to refer to Figure 3 and Figure 4 Among the multiple electrode grid holes 105 defined by two adjacent first electrode grid lines 1041, the first electrode grid holes 1051 and the second electrode grid holes 1052 are arranged alternately along the first direction X1.

[0026] By reasonably setting the position of the second electrode grid line 1042, multiple electrode grid holes 105 are formed between two adjacent first electrode grid lines 1041 along the second direction X2, and the first electrode grid holes 1051 and the second electrode grid holes 1052 are alternately arranged along the first direction X1, so as to avoid the large area of ​​non-light-emitting area generated by the concentrated setting of the second electrode grid holes 1052 and ensure the display effect of the display panel.

[0027] Optional, Figure 7 This is a partially enlarged structural diagram of another touch electrode provided in an embodiment of the present invention, as shown below. Figure 4 , Figure 6 and Figure 7 As shown, the multiple first electrode grid lines 1041 include a first A electrode grid line 41, a first B electrode grid line 42, and a first C electrode grid line 43 arranged sequentially along the second direction X2; the first A electrode grid line 41 and the first B electrode grid line 42 define multiple first A electrode grid holes 51 and multiple second A electrode grid holes 52, and the first B electrode grid line 42 and the first C electrode grid line 43 define multiple first B electrode grid holes 53 and multiple second B electrode grid holes 54; the first electrode grid holes 1051 include first A electrode grid holes 51 and first B electrode grid holes 53; along the second direction X2, the first A electrode grid holes 51 and the second B electrode grid holes 54 overlap, and the first B electrode grid holes 53 and the second A electrode grid holes 52 overlap.

[0028] Along the second direction X2, multiple first electrode grid lines 1041 include a first A electrode grid line 41, a first B electrode grid line 42, and a first C electrode grid line 43. By combining these with the second electrode grid lines 1042, the first A electrode grid lines 41 and 42 define multiple first A electrode grid holes 51 and multiple second A electrode grid holes 52. Along the third direction X3, the first A electrode grid holes 51 overlap with the light-emitting element 103, while the second A electrode grid holes 52 do not overlap with the light-emitting element 103. Similarly, the first B electrode grid holes 53 and multiple second B electrode grid holes 54 defined by the first B electrode grid lines 42 and 43 overlap with the light-emitting element 103 along the third direction X3, while the second B electrode grid holes 54 do not overlap with the light-emitting element 103. Along the second direction X2, the first electrode grid hole 51 overlaps with the second electrode grid hole 54, and the first electrode grid hole 53 overlaps with the second electrode grid hole 52, so that in the second direction X2, the electrode grid holes with light-emitting elements 103 and the electrode grid holes without light-emitting elements 103 are alternately arranged. By reasonably distributing the positions of the first electrode grid hole 53 and the second electrode grid hole 54, while ensuring that the light-shielding part 1062 effectively blocks the touch electrode 102, the electrode grid holes without light-emitting elements 103 are avoided from being concentrated, thus ensuring the display effect of the display panel.

[0029] Optional, continue to refer to Figure 4 and Figure 7 Along the third direction X3, the same first electrode mesh hole 1051 overlaps with at least two light-emitting elements 103.

[0030] In the third direction X3, the overlap of the same first electrode mesh hole 1051 with at least two light-emitting elements 103 can be understood as at least two light-emitting elements 103 being disposed within the defined area of ​​the same first electrode mesh hole 1051. Furthermore, the overlap of the same first electrode mesh hole 1051 with at least two light-emitting elements 103 is as follows: Figure 4 As shown, the same first electrode mesh hole 1051 overlaps with two light-emitting elements 103; as Figure 7 As shown, the same first electrode mesh hole 1051 overlaps with three light-emitting elements 103. In the third direction X3, the overlap of the same first electrode mesh hole 1051 with at least two light-emitting elements 103 can ensure that the first electrode mesh hole 1051 has a larger size in the first direction X1, or in other words, in the first direction X1, the size of the first electrode mesh hole 1051 is larger than the size of the second electrode mesh hole 1052, reducing the area ratio of electrode mesh holes without light-emitting elements 103, ensuring that a larger area in the display panel can have light-emitting display function, and ensuring the normal display effect of the display panel.

[0031] Optional, such as Figure 4 and Figure 7 As shown, among the at least two light-emitting elements 103 that overlap with the same first electrode mesh hole 1051 on the third direction X3, there are light-emitting elements 103 with different light-emitting colors.

[0032] In the at least two light-emitting elements 103 overlapping with the same first electrode mesh hole 1051 on the third-direction X3, the presence of light-emitting elements 103 with different emitting colors can be understood as light-emitting elements 103 with different emitting colors within the area defined by the same electrode mesh hole 105. This avoids the concentrated arrangement of light-emitting elements 103 with the same emitting color, ensuring that light-emitting elements 103 with different colors can share resources, facilitating pixel rendering between light-emitting elements 103 of different colors. Based on achieving the color display effect of the display panel, the display resolution of the display panel can be improved through pixel rendering between light-emitting elements 103 of different colors, thereby enhancing the display effect of the display panel.

[0033] Optional, continue to refer to Figure 6 and Figure 7The display panel includes a first light-emitting element group 108 and a second light-emitting element group 109. Both the first light-emitting element group 108 and the second light-emitting element group 109 include a first-color light-emitting element 1031, a second-color light-emitting element 1032, and a third-color light-emitting element 1033. The first-color light-emitting element 1031, the second-color light-emitting element 1032, and the third-color light-emitting element 1033 emit different colors. The first light-emitting element group 108 and the second light-emitting element group 109 are arranged alternately along a first direction X1 and an alternately along a second direction X2. Multiple first electrode grid lines 1041 include a first A electrode grid line 41, a first B electrode grid line 42, and a first C electrode grid line arranged sequentially along the second direction X2. Grid line 43; First electrode grid line 41 and first electrode grid line 42 define a plurality of first electrode grid holes 51, and first electrode grid line 42 and first electrode grid line 43 define a plurality of first electrode grid holes 53; first electrode grid hole 1051 includes first electrode grid hole 51 and first electrode grid hole 53; at least one light-emitting element 103 in the first light-emitting element group 108 is located in the first electrode grid hole 51, and at least one light-emitting element 103 is located in the first electrode grid hole 53; at least one light-emitting element 103 in the second light-emitting element group 109 is located in the first electrode grid hole 51, and at least one light-emitting element 103 is located in the first electrode grid hole 53.

[0034] The display panel includes a first light-emitting element group 108 and a second light-emitting element group 109. Both groups include a first-color light-emitting element 1031, a second-color light-emitting element 1032, and a third-color light-emitting element 1033, each emitting a different color. The arrangement of the light-emitting elements 103 in the first and second groups differs, forming two different arrangement patterns of the smallest repeating light-emitting units. Along the third direction X3, at least one light-emitting element 103 in the first light-emitting unit group overlaps with the first A electrode mesh hole 51, and at least one light-emitting element 103 overlaps with the first B electrode mesh hole 53. Similarly, at least one light-emitting element 103 in the second light-emitting element group 109 overlaps with the first A electrode mesh hole 51, and at least one light-emitting element 103 overlaps with the first B electrode mesh hole 53. For example, in the first light-emitting element group 108, the first color light-emitting element 1031 is located in the first electrode A mesh hole 51, and the second color light-emitting element 1032 and the third color light-emitting element 1033 are located in the first electrode B mesh hole 53; in the second light-emitting element group 109, the first color light-emitting element 1031 and the second color light-emitting element 1032 are located in the first electrode A mesh hole 51, and the third color light-emitting element 1033 is located in the first electrode B mesh hole 53. Both the first light-emitting element group 108 and the second light-emitting element group 109 include two rows of light-emitting elements 103. By reasonably setting the arrangement of the first light-emitting element group 108 and the second light-emitting element group 109, pixel rendering between different color light-emitting elements 103 in different light-emitting element groups can be achieved. On the basis of achieving the color display effect of the display panel, the display resolution of the display panel can be improved by the pixel rendering between different color light-emitting elements 103, thus ensuring the overall display effect of the display panel.

[0035] Optional, continue to refer to Figure 6 and Figure 7 The multiple first electrode grid lines 1041 include a first A electrode grid line 41, a first B electrode grid line 42, and a first C electrode grid line 43 arranged sequentially along the second direction X2; the first A electrode grid line 41 and the first B electrode grid line 42 define multiple first A electrode grid holes 51, and the first B electrode grid line 42 and the first C electrode grid line 43 define multiple first B electrode grid holes 53; the first electrode grid holes 1051 include first A electrode grid holes 51 and first B electrode holes 53; the display panel also includes multiple third light-emitting element groups 110 and multiple fourth light-emitting element groups 111, along the third direction X3, the third light-emitting element groups 110 overlap with the first A electrode grid holes 51, and the fourth light-emitting element groups 111 overlap with the first B electrode grid holes 53; the third light-emitting element group 110 includes at least two light-emitting elements 103 with different emitting colors, and the fourth light-emitting element group 111 includes at least two light-emitting elements 103 with different emitting colors.

[0036] The display panel further includes multiple third light-emitting element groups 110 and multiple fourth light-emitting element groups 111. The multiple third light-emitting elements 103 are arranged along a first direction X1, and the multiple fourth light-emitting element groups 111 are also arranged along the first direction X1. Along a third direction X3, at least two light-emitting elements 103 of different colors in the third light-emitting element group 110 overlap with the first electrode A mesh hole 51, and at least two light-emitting elements 103 of different colors in the fourth light-emitting element group 111 overlap with the first electrode B mesh hole 53. For example, the third light-emitting element group 110 includes a first-color light-emitting element 1031, a second-color light-emitting element 1032, and a third-color light-emitting element 1033, and the fourth light-emitting element group 111 includes a third-color light-emitting element 1033, a second-color light-emitting element 1032, and a third-color light-emitting element 1033. By rationally setting the arrangement of the light-emitting elements 103 in the third light-emitting element group 110 and the fourth light-emitting element group 111, pixel rendering between light-emitting elements 103 of different colors in different light-emitting element groups can be achieved. On the basis of achieving the color display effect of the display panel, the display resolution of the display panel can be improved by pixel rendering between light-emitting elements 103 of different colors, thus ensuring the display effect of the display panel.

[0037] Optional, continue to refer to Figure 7 Along the second direction X2, the first electrode A mesh hole 51 overlaps with the first electrode B mesh hole 53.

[0038] In the second direction X2, the first electrode A mesh hole 51 and the first electrode B mesh hole 53 overlap, resulting in an overlap between the third light-emitting element group 110 and the fourth light-emitting element group 111 in the second direction X2. For example, the first color light-emitting element 1031 in the third light-emitting element group 110 and the second color light-emitting element 1032 and the third color light-emitting element 1033 in the fourth light-emitting element group 111 form the first light-emitting element group 108, and the first color light-emitting element 1031 and the second color light-emitting element 1032 in the third light-emitting element group 110 and the third color light-emitting element 1033 in the fourth light-emitting element group 111 form the second light-emitting element group 109. Through the mutual combination of the light-emitting elements 103 in the third light-emitting element group 110 and the light-emitting elements 103 in the fourth light-emitting element group 111, first light-emitting element groups 108 and second light-emitting element groups 109 with different arrangements are achieved. By reasonably adjusting the setting position of each light-emitting element 103, the display effect of the display panel is guaranteed.

[0039] Optional, continue to refer to Figure 7The plurality of third light-emitting element groups 110 include a third A light-emitting element group 1101 and a third B light-emitting element group 1102. The number of light-emitting elements 103 in the third A light-emitting element group 1101 is the same as the number of light-emitting elements 103 in the third B light-emitting element group 1102. The combination of light-emitting elements 103 of different colors in the third A light-emitting element group 1101 is the same as the combination of light-emitting elements 103 of different colors in the third B light-emitting element group 103. The plurality of fourth light-emitting element groups 111 include a fourth A light-emitting element group 1111 and a fourth B light-emitting element group 1112. The number of light-emitting elements 103 in the fourth A light-emitting element group 1111 is the same as the number of light-emitting elements 103 in the fourth B light-emitting element group 1112. The combination of light-emitting elements 103 of different colors in the fourth A light-emitting element group 103 is the same as the combination of light-emitting elements 103 of different colors in the fourth B light-emitting element group 103.

[0040] Along the first direction X1, the third light-emitting element group 1101 and the third light-emitting element group 1102 in the plurality of third light-emitting element groups 110 are arranged alternately. For example, both the third light-emitting element group 1101 and the third light-emitting element group 1102 include a first color light-emitting element 1031, a second color light-emitting element 1032, and a first color light-emitting element 1031. Along the first direction X1, the fourth light-emitting element group 1111 and the fourth light-emitting element group 1112 in the plurality of fourth light-emitting element groups 111 are arranged alternately. Both the fourth light-emitting element group 1111 and the fourth light-emitting element group 1112 include a third color light-emitting element 1033, a second color light-emitting element 1032, and a third color light-emitting element 1033. In the first direction X1, each first electrode A grid hole 51 is provided with a third light-emitting element group 110 with the same arrangement of light-emitting elements 103, and each first electrode B grid hole 53 is provided with a fourth light-emitting element group 111 with the same arrangement of light-emitting elements 103, so as to ensure that the arrangement of the third light-emitting element group 110 and the fourth light-emitting element group 111 is more neat and to ensure the display effect of the display panel.

[0041] Optional, Figure 8 This is a partially enlarged structural diagram of another touch electrode provided in an embodiment of the present invention, as shown below. Figure 6 , Figure 7 and Figure 8As shown, the third group of light-emitting elements 1101 includes a first-color light-emitting element 1031, a second-color light-emitting element 1032, and a first-color light-emitting element 1031 arranged along the first direction X1; the fourth group of light-emitting elements 1111 includes a third-color light-emitting element 1033, a second-color light-emitting element 1032, and a third-color light-emitting element 1033 arranged along the first direction X1; or, the third group of light-emitting elements 1101 includes a second-color light-emitting element 1032, a first-color light-emitting element 1031, and a second-color light-emitting element 1032 arranged along the first direction X1; the fourth group of light-emitting elements 1111 includes a third-color light-emitting element 1033, a first-color light-emitting element 1031, and a third-color light-emitting element 1033 arranged along the first direction X1.

[0042] In the prior art, the distance between the first color light-emitting element 1031 and the second color light-emitting element 1032 is smaller than the distance between the second color light-emitting element 1032 and the third color light-emitting element 1033, and the distance between the second color light-emitting element 1032 and the third color light-emitting element 1033 is smaller than the distance between the first color light-emitting element 1031 and the third color light-emitting element 1033. Considering that the distance between the first color light-emitting element 1031 and the second color light-emitting element 1032 is small, the corresponding light-shielding part 1062 has the problem that it cannot completely cover the electrode grid line 104 of the touch electrode 102. Therefore, by adjusting the setting position of the first color light-emitting element 1031 or the second color light-emitting element 1032 between the third A light-emitting element groups 1101 in the first direction X1, a pixel space is formed, as shown in the area defined by the second A electrode grid hole 52 in the figure. The light-shielding part 1062 between the adjacent third A light-emitting element groups 1101 corresponding to this pixel space can completely block the electrode grid line 104 of the touch electrode 102, reducing the metal reflection light. Similarly, the first color light-emitting element 1031 or the second color light-emitting element 1032 between the fourth A light-emitting element group 1111 can be removed to form pixel vacancies, as shown in the area defined by the second B electrode grid hole 54 in the figure. The light-shielding part 1062 between the adjacent fourth A light-emitting element group 1111 corresponding to this pixel vacancies can completely block the electrode grid line 104 of the touch electrode 102, reducing the metal reflection light.

[0043] It is understood that the arrangement of light-emitting elements 103 of different colors in the third group of light-emitting elements 1101 and the fourth group of light-emitting elements 1111 can have different configurations. The following describes two possible implementation methods.

[0044] like Figure 7As shown, the third A light-emitting element group 1101 includes a first-color light-emitting element 1031, a second-color light-emitting element 1032, and a first-color light-emitting element 1031 arranged along the first direction X1; the fourth A light-emitting element group 1111 includes a third-color light-emitting element 1033, a second-color light-emitting element 1032, and a third-color light-emitting element 1033 arranged along the first direction X1. By removing the second-color light-emitting element 1032 in adjacent third A light-emitting element groups 1101 and adjusting the setting position of the second-color light-emitting element 1032 in adjacent fourth A light-emitting element groups 1111, the number of light-emitting elements 103 in the third A light-emitting element groups 1101 and the fourth A light-emitting element groups 1111 is the same, and the arrangement of the light-emitting elements 103 in the third A light-emitting element groups 1101 and the fourth A light-emitting element groups 1111 is reasonably set, so that pixel rendering between different color light-emitting elements 103 in the third A light-emitting element groups 1101 and the fourth A light-emitting element groups 1111 is realized, ensuring the display effect of the display panel.

[0045] like Figure 8 As shown, the third group of light-emitting elements 1101 includes a second-color light-emitting element 1032, a first-color light-emitting element 1031, and a second-color light-emitting element 1032 arranged along the first direction X1; the fourth group of light-emitting elements 1111 includes a third-color light-emitting element 1033, a first-color light-emitting element 1031, and a third-color light-emitting element 1033 arranged along the first direction X1. The second-color light-emitting element 1032 and the first-color light-emitting element 1031 in the third group of light-emitting elements 1101 and the third-color light-emitting element 1033 in the fourth group of light-emitting elements 1111 form a first light-emitting element group 108, and the second-color light-emitting element 1032 in the third group of light-emitting elements 1101 and the first-color light-emitting element 1031 and the third-color light-emitting element 1033 in the fourth group of light-emitting elements 1111 form a second light-emitting element group 109. By removing the first color light-emitting element 1031 from the adjacent third light-emitting element group 1101 and the first color light-emitting element 1031 from the adjacent fourth light-emitting element group 1111, the number of light-emitting elements 103 in the third light-emitting element group 1101 and the fourth light-emitting element group 1111 is made the same, thereby achieving pixel rendering between different color light-emitting elements 103 in the third light-emitting element group 1101 and the fourth light-emitting element group 1111, and ensuring the display effect of the display panel.

[0046] Optional, continue to refer to Figure 6 and Figure 7 Along the third direction X3, the minimum distance between two light-emitting elements 103 with different emitting colors in the third light-emitting element group 110 is L1, and the minimum distance between two light-emitting elements 103 with different emitting colors in the fourth light-emitting element group 111 is L2. ≤10%.

[0047] In the prior art, the spacing between the first color light-emitting element 1031 and the second color light-emitting element 1032 is smaller than the spacing between the second color light-emitting element 1032 and the third color light-emitting element 1033. Because the spacing between the first color light-emitting element 1031 and the second color light-emitting element 1032 is relatively small, the corresponding light-shielding portion 1062 cannot completely block the electrode grid lines 104 of the touch electrode 102. In this invention, pixel gaps are formed between the third light-emitting element group 110 and between the fourth light-emitting element group 111, ensuring sufficient space for designing the electrode grid lines 104 of the touch electrode 102. In the third light-emitting element group 110, touch electrodes 102 are not provided between different colored light-emitting elements 103, and in the fourth light-emitting element group 111, touch electrodes 102 are not provided between different colored light-emitting elements 103. While maintaining the minimum distance L1 between two light-emitting elements 103 with different emitting colors in the third light-emitting element group 110, the minimum distance L2 between two light-emitting elements 103 with different emitting colors in the fourth light-emitting element group 111 can be appropriately reduced. This makes the minimum distance L1 between two light-emitting elements 103 with different emitting colors in the third light-emitting element group 110 the same as or similar to the minimum distance L2 between two light-emitting elements 103 with different emitting colors in the fourth light-emitting element group 111. Reducing the distance between the light-emitting elements 103 in the fourth light-emitting element group 111 is beneficial to increasing the pixel aperture ratio and ensuring the display effect of the display panel.
