[0036] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0037] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0039] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0040] An embodiment of the present invention provides a display panel, such as Figure 1 As shown, Figure 1 A schematic top view of a display panel provided in an embodiment of the present invention includes: a substrate 1; a plurality of first touch electrodes 21 located on one side of the substrate 1 and extending along a first direction h11 and arranged along a second direction h12; and a plurality of second touch electrodes 22 extending along the second direction h12 and arranged along the first direction h11; the first direction h11 and the second direction h12 intersect. Figure 1 As an example, the first direction h11 and the second direction h12 are perpendicular to each other. In the embodiment of the present invention, one of the first touch electrode 21 and the second touch electrode 22 is a touch driving electrode, and the other is a touch sensing electrode.

[0041] Optional, combined Figure 2 、 Figure 3 and Figure 4 As shown, Figure 2 for Figure 1 An enlarged schematic diagram of the middle region Q1, Figure 3 for Figure 2 A schematic cross-sectional view along BB', Figure 4 for Figure 2 A schematic diagram of the first touch electrode and sub-pixel in the embodiment of the present invention, in an embodiment of the present invention, the first touch electrode 21 includes a first main electrode 211 and a first connecting portion 212. In an embodiment of the present invention, two adjacent first main electrodes 211 are electrically connected through at least two first connecting portions 212. Figure 2 and Figure 4 As an example, two adjacent first main electrodes 211 are electrically connected via two first connecting portions 212. Based on this arrangement, more connection paths can be provided between the two adjacent first main electrodes 211, making the electrical connection between the two adjacent first main electrodes 211 more reliable.

[0042] Combine Figure 2 and Figure 5 As shown, Figure 5For Figure 2 A schematic view of a second touch electrode and a sub-pixel in the display panel, the second touch electrode 22 includes a second main electrode 221 and a second connecting part 222. In the embodiment of the present application, two adjacent second main electrodes 221 are electrically connected by at least two second connecting parts 222. Figure 2 And Figure 5 For example, two adjacent second main electrodes 221 are electrically connected by two second connecting parts 222. Based on this arrangement, the connection path between two adjacent second main electrodes 221 can be increased, so that the electrical connection between two adjacent second main electrodes 221 is more reliable.

[0043] As shown in Figure 4 , the first main electrode 211 includes a first metal line 201 and a second metal line 202 which are intersected and electrically connected; the first metal line 201 and the second metal line 202 cross to form a grid opening.

[0044] As shown in Figure 5 , the second main electrode 221 includes a first metal line 201 and a second metal line 202 which are intersected and electrically connected; the first metal line 201 and the second metal line 202 cross to form a grid opening.

[0045] The cross arrangement of the first metal line 201 and the second metal line 202 can increase the conduction path of the touch signal in the first touch electrode 21, and increase the conduction path of the touch signal in the second touch electrode 22, reduce the resistance of the first touch electrode 21 and the second touch electrode 22, and reduce the delay of the touch signal in the touch operation, and improve the touch effect of the display panel.

[0046] For example, the material of the first metal line 201 and the second metal line 202 includes aluminum, copper, chromium, nickel, etc.

[0047] As shown in Figure 2 , Figure 4 and Figure 5 , the display panel further includes a sub-pixel 3. In the embodiment of the present application, the first metal line 201 and the second metal line 202 are arranged away from the sub-pixel 3, that is, the orthogonal projection of the sub-pixel 3 on the plane where the substrate 1 is located and the orthogonal projection of the first metal line 201 on the plane where the substrate 1 is located do not overlap, and the orthogonal projection of the sub-pixel 3 on the plane where the substrate 1 is located and the orthogonal projection of the second metal line 202 on the plane where the substrate 1 is located do not overlap. Based on this arrangement, the first metal line 201 and the second metal line 202 can avoid affecting the light emission of the sub-pixel 2, and ensure the display effect of the display panel. For example, the line width of the first metal line 201 and the second metal line 202 is smaller than the distance between two adjacent sub-pixels 3, and the orthogonal projection of the first metal line 201 and the second metal line 202 on the plane where the substrate 1 is located can be respectively located between two adjacent sub-pixels 3.

[0048] In the embodiments of the present application, as shown in Figure 6 , Figure 6 FIG. 1 is a schematic view of a cross section of a display panel provided in an embodiment of the present application. The display panel comprises a pixel definition layer 30, the pixel definition layer comprising a pixel opening 300, a sub-pixel 3 comprising a first electrode 31, a second electrode 32 and a light-emitting layer 33, at least part of the light-emitting layer 33 being located within the pixel opening 300. The first metal line 201 and the second metal line 202 are located between two adjacent pixel openings 300 in the orthogonal projection of the plane on which the substrate 1 is located. Optionally, the sub-pixel 3 comprises an organic light-emitting diode or an inorganic light-emitting diode. Figure 5 The display panel is taken as an OLED display panel as an example for illustration.

[0049] It should be noted that the arrangement of the sub-pixel 3 in Figure 2 , Figure 4 and Figure 5 is only illustrative and does not limit the present application.

[0050] In the embodiments of the present application, as shown in Figure 2 and Figure 4 , the first connecting portion 212 is in a linear structure. The linear structure means that the first connecting portion 212 does not comprise an additional protruding structure in a direction other than the extension direction of the first connecting portion 212. Illustratively, the linear structure comprises any one of a straight line type, a broken line type and a curved line type.

[0051] In the embodiments of the present application, by setting the first connecting portion 212 in a linear structure, the parasitic capacitance between the first connecting portion and the second connecting portion can be reduced when a touch operation is performed, which is conducive to improving the touch performance of the display panel.

[0052] Illustratively, in combination with Figure 2 and Figure 3 , in the embodiments of the present application, the second connecting portion 222, the first main electrode 211 and the second main electrode 221 can be provided in the same layer. Based on this arrangement, the same material can be used and the second connecting portion 222, the first main electrode 211 and the second main electrode 221 can be formed simultaneously in the same process when the display panel is prepared, which is conducive to simplifying the preparation process of the display panel.

[0053] The second connecting portion 222 and the second main electrode 221 provided in the same layer and electrically connected can be directly connected in contact.

[0054] It should be noted that, in order to clearly distinguish different structures and illustrate the positional relationship between the structures, Figure 2 , Figure 4 and Figure 5Different structures are schematically shown in different filling patterns, for example, the second connecting part 222, the first main electrode 211 and the second main electrode 221 located in the same film layer are also schematically shown in different filling patterns.

[0055] Optionally, as shown in Figure 7 , Figure 7 Another schematic view of a first touch electrode and a sub-pixel is provided for an embodiment of the present application, wherein the first touch electrode 21 further comprises a third connecting part 213, and the third connecting part 213 is electrically connected with the first main electrode 211 and the first connecting part 212 respectively. The third connecting part 213 can enhance the connection reliability between two adjacent first main electrodes 211.

[0056] As shown in Figure 7 , the third connecting part 213 comprises a third alpha connecting part 2131 and a third beta connecting part 2132, the two ends of the third alpha connecting part 2131 are electrically connected with the first main electrode 211 through the via hole 410, and the third beta connecting part 2132 is electrically connected with the first connecting part 212.

[0057] Exemplarily, as shown in Figure 7 , the extension direction of the third alpha connecting part 2131 is parallel to the extension direction of the first metal line 201, and the extension direction of the third beta connecting part 2132 is parallel to the extension direction of the second metal line 202.

[0058] Optionally, the third connecting part 213 and the first connecting part 212 can be arranged in the same layer, and the two can be directly electrically connected to simplify the preparation process of the display panel.

[0059] In an optional embodiment, the shape of the first connecting part 212 can be set as a broken line type. As shown in Figure 2 , Figure 4 and Figure 7 , the first connecting part 212 comprises a first sub-connecting part 2121 and a second sub-connecting part 2122 which are electrically connected and intersected in the extension direction, the extension direction of the first sub-connecting part 2121 is parallel to the extension direction of the first metal line 201, and the extension direction of the second sub-connecting part 2122 is parallel to the extension direction of the second metal line 202.

[0060] Optionally, as shown in Figure 2As shown, along the extension direction of the second metal line 202, the first sub-connection part 2121 and the first metal line 201 of the second main electrode 221 closest to the first sub-connection part 2121 are spaced apart by one sub-pixel 3. Based on this arrangement, the distance between the first sub-connection part 2121 and the second main electrode 221 can be shortened, and the first sub-connection part 2121 is arranged as close to the second main electrode 221 as possible, which is conducive to enhancing the coupling capacitance between the two, and the change amount of the coupling capacitance between the two can also be improved when a touch operation occurs, thereby improving the touch sensitivity of the display panel and improving the touch effect of the display panel.

[0061] As shown in FIG. 2, the first sub-connection part 212 is arranged between the first main electrode 211 and the second main electrode 221. Figure 2 As shown, along the extension direction of the first metal line 201, the second sub-connection part 2122 and the second metal line 202 of the second main electrode 221 closest to the second sub-connection part 2122 are spaced apart by one sub-pixel 3. Based on this arrangement, the distance between the second sub-connection part 2122 and the second main electrode 221 can be shortened, and the second sub-connection part 2122 is arranged as close to the second main electrode 221 as possible, which is conducive to enhancing the coupling capacitance between the two and improving the touch effect of the display panel.

[0062] In another alternative embodiment, the shape of the first connection part 212 can also be arranged as a straight line. As shown in FIG. 2, the first connection part 212 is arranged between the first main electrode 211 and the second main electrode 221. Figure 8 As shown, Figure 8 As shown, Figure 1 As shown in FIG. 2, the first connection part 212 is arranged between the first main electrode 211 and the second main electrode 221.

[0063] As shown in FIG. 2, the first connection part 212 is arranged between the first main electrode 211 and the second main electrode 221. Figure 8 As shown, along the extension direction of the second metal line 202, the two first connection parts 212 connecting the adjacent two first main electrodes 211 are located on opposite sides of the same grid opening K, wherein the grid opening K covers one sub-pixel 3 in the orthographic projection of the substrate on the plane. Figure 8 That is, the two first connection parts 212 connecting the adjacent two first main electrodes 211 are located on opposite sides of the same sub-pixel.

[0064] As shown in FIG. 2, the first connection part 212 is arranged between the first main electrode 211 and the second main electrode 221. Figure 8 As shown, along the extension direction of the second metal line 202, the two first connection parts 212 connecting the adjacent two first main electrodes 211 are spaced apart by one grid opening K and one sub-pixel.

[0065] As shown in FIG. 2, the first connection part 212 is arranged between the first main electrode 211 and the second main electrode 221. Figure 2 , Figure 3 and Figure 4As shown, in the direction perpendicular to the plane where the substrate 1 is located, the first connecting part 212 and the first main electrode 211 at least partially overlap, and the first connecting part 212 and the first main electrode 211 comprise a first insulating layer 40 therebetween, the first insulating layer 40 comprises a via hole 410; the first connecting part 212 is electrically connected with a first main electrode 211 through at least two via holes 410, so as to enhance the connection reliability of the first connecting part 212 and the first main electrode 211, and improve the touch performance of the display panel.

[0066] Optionally, the first connecting part 212 comprises at least one sub-connecting part 2120, in the embodiment of the present application, the shape of the sub-connecting part 2120 is a straight line. That is, the sub-connecting part 2120 is a structure with a single extension direction. Figure 2 、 Figure 4 and Figure 7 In the embodiment of the present application, the first connecting part 212 comprises two sub-connecting parts 2120, which can be a first sub-connecting part 2121 and a second sub-connecting part 2122 respectively. Figure 8 In the embodiment of the present application, the first connecting part 212 comprises one sub-connecting part 2120 as an example.

[0067] In the embodiment of the present application, in the direction perpendicular to the plane where the substrate 1 is located, the sub-connecting part 2120 partially overlaps with at least two via holes 410, and the sub-connecting part 2120 is electrically connected with the first main electrode 211 through the at least two via holes 410, so as to enhance the connection reliability of the first main electrode 211 and the sub-connecting part 2120.

[0068] Moreover, the arrangement direction of the two adjacent via holes 410 is parallel to the extension direction of the sub-connecting part 2120; along the extension direction of the sub-connecting part 2120, the two adjacent via holes 410 are spaced apart by one sub-pixel 3. Based on the above arrangement mode, the distance between the two adjacent via holes 410 can be avoided to be too far, while ensuring the electrical connection between the first main electrode 211 and the sub-connecting part 2120, the length of the part of the sub-connecting part 2120 overlapping with the first main electrode 211 does not need to be set too long, the film layer of the part of the sub-connecting part 2120 overlapping with the first main electrode 211 is different from other positions, the part is a double-layer metal structure comprising the sub-connecting part 2120 and the part of the first main electrode 211 overlapping with the sub-connecting part 2120, while other positions only comprise a single-layer metal, if the length of the part is too long, on the one hand, the visibility of the part will be increased, on the other hand, the impedance of the sub-connecting part 2120 will also be increased. Based on the above arrangement mode, the length of the part of the sub-connecting part 2120 overlapping with the first main electrode 211 can be reduced, which is conducive to enhancing the display consistency of the display panel in different areas, and reducing the impedance of the sub-connecting part 2120.

[0069] As Figure 2 ,Figure 4 and Figure 7 As shown in FIG. 12, the first sub-connection portion 2121 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the first sub-connection portion 2121. Along the extension direction of the first sub-connection portion 2121, the adjacent two through holes 410 are spaced apart by one sub-pixel 3. Also, the second sub-connection portion 2122 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the second sub-connection portion 2122. Along the extension direction of the second sub-connection portion 2122, the adjacent two through holes 410 are spaced apart by one sub-pixel 3.

[0070] As shown in FIG. 12, the first sub-connection portion 2121 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the first sub-connection portion 2121. Along the extension direction of the first sub-connection portion 2121, the adjacent two through holes 410 are spaced apart by one sub-pixel 3. Also, the second sub-connection portion 2122 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the second sub-connection portion 2122. Along the extension direction of the second sub-connection portion 2122, the adjacent two through holes 410 are spaced apart by one sub-pixel 3. Figure 8 As shown in FIG. 12, the first sub-connection portion 2121 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the first sub-connection portion 2121. Along the extension direction of the first sub-connection portion 2121, the adjacent two through holes 410 are spaced apart by one sub-pixel 3. Also, the second sub-connection portion 2122 partially overlaps with at least two through holes 410 in a direction perpendicular to the plane on which the substrate 1 lies, and the arrangement direction of the adjacent two through holes 410 is parallel to the extension direction of the second sub-connection portion 2122. Along the extension direction of the second sub-connection portion 2122, the adjacent two through holes 410 are spaced apart by one sub-pixel 3.

[0071] For example, in the embodiment of the present application, the first connection portion 212 includes at least one of the first sub-connection portion 2121 and the second sub-connection portion 2122, Figure 4 For example, in the embodiment of the present application, the first connection portion 212 includes at least one of the first sub-connection portion 2121 and the second sub-connection portion 2122,

[0072] The extension direction of the first sub-connection part 2121 is parallel to the extension direction of the first metal line 201, and the extension direction of the second sub-connection part 2122 is parallel to the extension direction of the second metal line 202; the length of the first sub-connection part 2121 is L11, and the distance between two adjacent second metal lines 202 along the extension direction of the first sub-connection part 2121 is L22, L11≥3L22. The length of the second sub-connection part 2122 is L12, and the distance between two adjacent first metal lines 201 along the extension direction of the second sub-connection part 2122 is L21, L12≥3L21. Wherein, the distance L22 between two adjacent second metal lines 202 can be the sum of the line width W02 of the second metal line 202 and the shortest distance L02 between two adjacent second metal lines 202. The distance L21 between two adjacent first metal lines 201 can be the sum of the line width W01 of the first metal line 201 and the shortest distance L01 between two adjacent first metal lines 201. Based on the above arrangement, on the one hand, the arrangement of the metal lines constituting the first main electrode 211 can be simplified, and on the other hand, when arranging the second connection part 222 connecting two adjacent second main electrodes 221, since the second connection part 222 needs to pass through the position overlapping with the first connection part 212, based on the above arrangement, enough space can be left for the arrangement of the second connection part 222, which is beneficial to increase the number of the second connection part 222, reduce the difficulty of the arrangement of the second connection part 222, and balance the impedance of the first connection part 212 and the second connection part 222.

[0073] As shown in Figure 2 , Figure 8 and Figure 9 , Figure 9 is a schematic diagram of a relative position relationship of the first connection part and the second connection part in Figure 2 , the first connection part 212 and the second connection part 222 partially overlap in the direction perpendicular to the plane where the substrate 1 is located. The first connection part 212 and the second connection part 222 are arranged in different layers and are insulated from each other.

[0074] In an optional embodiment, the shape of the second connection part 222 can be set as a broken line type. Figure 2 , Figure 5 and Figure 9 , the second connection part 222 includes a third sub-connection part 2221, a fourth sub-connection part 2222 and a fifth sub-connection part 2223, and the third sub-connection part 2221 and the fourth sub-connection part 2222 are electrically connected through the fifth sub-connection part 2223.

[0075] As shown in Figure 9As shown, among the at least two first connecting parts 212 connecting the two adjacent first main body electrodes 211, one of the first connecting parts 212 and the third sub connecting part 2221 at least partially overlap in the direction perpendicular to the plane where the substrate 1 is located, and the other first connecting part 212 and the fourth sub connecting part 2222 at least partially overlap; the fifth sub connecting part 2223 includes a fifth alpha sub connecting part 22231 and a fifth beta sub connecting part 22232, the third sub connecting part 2221 and the fifth beta sub connecting part 22232 are electrically connected through the fifth alpha sub connecting part 22231, and the fourth sub connecting part 2222 and the fifth alpha sub connecting part 22231 are electrically connected through the fifth beta sub connecting part 22232. In the embodiment of the present application, the extension direction of the fourth sub connecting part 2222 and the extension direction of the fifth alpha sub connecting part 22231 are both parallel to the extension direction of the first metal line 201, and the extension direction of the third sub connecting part 2221 and the extension direction of the fifth beta sub connecting part 22232 are both parallel to the extension direction of the second metal line 202.

[0076] As shown in the figure, Figure 2 As shown in the figure, along the extension direction of the first metal line 201, the third sub connecting part 2221 and the second metal line 202 of the first main body electrode 211 closest to it are separated by one sub pixel 3, based on this arrangement, the distance between the third sub connecting part 2221 and the first main body electrode 211 can be shortened, and the third sub connecting part 2221 is arranged as close to the first main body electrode 211 as possible, which is conducive to enhancing the coupling capacitance between the two and improving the touch effect of the display panel.

[0077] Continuing to refer to Figure 2 , the fifth beta sub connecting part 22232 and the second metal line 202 of the first main body electrode 211 closest to it are separated by one sub pixel 3; based on this arrangement, the distance between the fifth beta sub connecting part 22232 and the first main body electrode 211 can be shortened, and the fifth beta sub connecting part 22232 is arranged as close to the first main body electrode 211 as possible, which is conducive to enhancing the coupling capacitance between the two and improving the touch effect of the display panel.

[0078] Continuing to refer to Figure 2 , along the extension direction of the second metal line 202, the fourth sub connecting part 2222 and the first metal line 201 of the first main body electrode 211 closest to it are separated by one sub pixel 3, to shorten the distance between the fourth sub connecting part 2222 and the first main body electrode 211, and the fourth sub connecting part 2222 is arranged as close to the first main body electrode 211 as possible, which is conducive to enhancing the coupling capacitance between the two and improving the touch effect of the display panel.

[0079] Continuing to refer to Figure 2The fifth A-sub connecting part 22231 and the first metal line 201 closest to the first main body electrode 211 are separated by one sub-pixel 3, so as to shorten the distance between the fifth A-sub connecting part 22231 and the first main body electrode 211, and make the fifth A-sub connecting part 22231 as close as possible to the first main body electrode 211, which is beneficial to enhance the coupling capacitance between the two and improve the touch effect of the display panel.

As shown in Figure 8 , for example, the extension direction of the second connecting part 222 is designed to be parallel to the extension direction of the second metal line 202.

[0082] As shown in Figure 2 and Figure 10 , Figure 10 , FIG. 4 is a schematic view of a dummy electrode and a sub-pixel in Figure 2 , and the display panel further comprises a dummy electrode 4. The dummy electrode 4 comprises a first sub-dummy electrode 41, which is located between two adjacent fifth sub connecting parts 2223 along the first direction h11. In the embodiment of the present application, the first sub-dummy electrode 41 does not receive an electrical signal, i.e., is in a potential floating state. The first sub-dummy electrode 41 and the fifth sub connecting part 2223 are insulated from each other. As an example, the first sub-dummy electrode 41 can be disposed in the same layer as the first main body electrode 211.

That is, the third metal line 203 and the fourth metal line 204 do not overlap with the sub-pixel 3 in the orthographic projection of the substrate 1, so as to avoid affecting the light emission of the sub-pixel 3.

[0087] Optionally, the sub-pixel 3 closed by the orthographic projection of the first grid 200 on the substrate 1 can be a red sub-pixel emitting red light, or can be a green sub-pixel emitting green light, or can be a blue sub-pixel emitting blue light.

In the embodiment of the present application, the touch unit 2 can be regarded as the smallest repeating unit in the touch electrode, and a plurality of touch units 2 can be arranged in the first direction h11 and the second direction h12 to cover the touch area of the display panel.

[0089] As shown in Figure 1 and Figure 10 The first grid 200 includes a first central grid 2001, and the geometric center C of the touch unit 2 is located in the first central grid 2001. In the embodiment of the present application, the light emission color of the sub-pixel 3 corresponding to the first central grid 2001 in different touch units 2 is the same. Based on this arrangement, the touch unit 2 and the sub-pixel 3 in different areas can have the most consistent relative position relationship, and the display uniformity in different areas of the display panel can be improved.

In addition, the arrangement of the second sub-virtual electrode 42 can also reduce the parasitic capacitance generated between the touch electrode and other conductive film layers in the display panel, and reduce the possibility of abnormality such as horizontal lines and dark lines in the display picture.

[0093] When the second sub-virtual electrode 42 and the first main electrode 211 are arranged in the same layer, a gap G needs to be arranged between them to ensure mutual insulation. As shown in FIG. 8, the second sub-virtual electrode 42 is cut off at the intersection of the first metal line 201 and the second metal line 202 of the first main electrode 211. It can be understood that the position of the intersection of the first metal line 201 and the second metal line 202 in the first main electrode 211 is the boundary of the first main electrode 211, and the intersection as the boundary is separated from the second sub-virtual electrode 42 by the gap G.

Figure 2As shown, the first main electrode 211 also includes a first protrusion 2111 and a second protrusion 2112. Along the extension direction of the first metal wire 201, the first protrusion 2111 protrudes from the intersection of the first metal wire 201 and the second metal wire 202 of the first main electrode 211; along the extension direction of the second metal wire 202, the second protrusion 2112 protrudes from the intersection of the first metal wire 201 and the second metal wire 202 of the first main electrode 211; the length of the first protrusion 2111 is less than the distance between two adjacent second metal wires 202; the length of the second protrusion 2112 is less than the distance between two adjacent first metal wires 201.

[0095] Exemplarily, the locations of the first protrusion 2111 and the second protrusion 2112 may serve as a portion of the boundary of the first main electrode 211 .

[0096] like Figure 2 As shown, the first main electrode 211 may include multiple first protrusions 2111 and multiple second protrusions 2112, wherein at least part of the first protrusions 2111 are located on a side of the first main electrode 211 close to the second main electrode 221, and at least part of the second protrusions 2112 are located on a side of the first main electrode 211 close to another second main electrode 221.

[0097] Or, as Figure 13 As shown, Figure 13 A schematic diagram of a first main electrode, a second main electrode, a second connecting portion and a dummy electrode provided in an embodiment of the present invention, in addition to the first protrusion 2111 and the second protrusion 2112 located on the side of the first main electrode 211 close to the second main electrode 221, the first main electrode 211 may also include a first protrusion 2111 located on the side of the first main electrode 211 close to the second connecting portion 222, and a second protrusion 2112 located on the side of the first main electrode 211 close to the second connecting portion 222.

[0098] like Figure 13 As shown, in this embodiment of the present invention, the second sub-dummy electrode 42 can be disposed between the first protruding portion 2111 and the second connecting portion 222. A gap G is defined between the second sub-dummy electrode 42 and the first main electrode 211, with a portion of the gap G located between the second sub-dummy electrode 42 and the first protruding portion 2111 and another portion of the gap G located between the second sub-dummy electrode 42 and the second protruding portion 2112.

[0099] For example, Figure 2 and Figure 10As shown, the dummy electrode 4 further includes a third sub dummy electrode 43. The third sub dummy electrode 43 is located between the second main electrode 221 and the first sub dummy electrode 41. In the embodiment of the present application, the third sub dummy electrode 43 does not receive electrical signals, i.e., is in a floating potential state. The third sub dummy electrode 43 is mutually insulated from the second main electrode 221 and the first sub dummy electrode 41, respectively. Exemplarily, the third sub dummy electrode 43 can be arranged in the same layer as the first main electrode 211.

[0100] The arrangement of the third sub dummy electrode 43 can improve the consistency of the reflectivity of the area in the display panel where the touch electrode is arranged and the area where the touch electrode is not arranged, such as the area where the third sub dummy electrode 43 is located, and further improve the display uniformity of the display panel. In addition, the arrangement of the third sub dummy electrode 43 can also reduce the parasitic capacitance generated between the touch electrode and other conductive film layers in the display panel, and reduce the possibility of abnormality such as horizontal lines and dark lines in the display picture.

[0101] Exemplarily, as shown in FIG. 4, the first sub dummy electrode 41 can be arranged in the same layer as the first main electrode 211. Figure 5 As shown, the second main electrode 221 further includes a third protruding portion 2211 and a fourth protruding portion 2212. Along the extension direction of the first metal line 201, the third protruding portion 2211 protrudes from the intersection of the first metal line 201 and the second metal line 202 of the second main electrode 221. Along the extension direction of the second metal line 202, the fourth protruding portion 2212 protrudes from the intersection of the first metal line 201 and the second metal line 202 of the second main electrode 221. The length of the third protruding portion 2211 is less than the distance between two adjacent second metal lines 202. The length of the fourth protruding portion 2212 is less than the distance between two adjacent first metal lines 201.

Part of the gap G is located between the third sub dummy electrode 43 and the third protruding portion 2211, and the other part of the gap G is located between the third sub dummy electrode 43 and the fourth protruding portion 2212. Based on this arrangement, the third sub dummy electrode 43 can occupy more area between the second main electrode 221 and the first sub dummy electrode 41, and further improve the display uniformity of the display panel.

[0103] Alternatively, as shown in FIG. 7, Figure 13As shown, the third dummy electrode 43 can also be arranged to stop at the intersection of the first metal line 201 and the second metal line 202 of the second main electrode 221. When the third dummy electrode 43 and the second main electrode 221 are arranged in the same layer, a gap G needs to be arranged between the two to ensure mutual insulation therebetween. As shown, the third dummy electrode 43 stops at the intersection of the first metal line 201 and the second metal line 202 of the second main electrode 221. It can be understood that the position of the intersection of the first metal line 201 and the second metal line 202 in the second main electrode 221 is the boundary of the second main electrode 221, and the intersection as the boundary is separated from the third dummy electrode 43 by the gap G.

[0104] Optionally, the dummy electrode 4 is arranged in the same layer as the first main electrode 211. As an example, the first dummy electrode 41, the second dummy electrode 42, and the third dummy electrode 43 can all be arranged in the same layer as the first main electrode 211, so as to simplify the manufacturing process of the display panel, and reduce the number of film layers in the display panel and the thickness of the display panel.

[0105] As an example, as shown in FIG. 4, the first dummy electrode 41, the second dummy electrode 42, and the third dummy electrode 43 are arranged in the same layer as the first main electrode 211.
