For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0057] Figure 2 This is a plan view of a display panel provided in an embodiment of this application. Figure 18 This is an enlarged schematic diagram of a touch unit provided in an embodiment of this application.

[0058] This application embodiment provides a display panel 01, combined with... Figure 17 and Figure 19As shown, the display panel 01 includes a plurality of touch units 100, the touch unit 100 includes a first touch electrode 11 and a second touch electrode 12, the first touch electrode 11 is electrically insulated from the second touch electrode 12.

[0059] In the display panel 01, the touch units 100 can be arranged in a row direction and a column direction, in the plurality of touch units 100 arranged in the column direction, the first touch electrodes 11 in the touch units 100 can be electrically connected in sequence; in the plurality of touch units 100 arranged in the row direction, the second touch electrodes 12 in the touch units 100 can be electrically connected in sequence. When a user touches the display panel 01, the control system can calculate the coordinates of the touch point according to the size of the mutual capacitance between the first touch electrode 11 and the second touch electrode 12 in the touch unit 100.

[0060] The first touch electrode 11 includes a first main electrode 111 and a first connecting part 112, in the same first touch electrode 11, two adjacent first main electrodes 111 are electrically connected by the first connecting part 112.

[0061] For example, as shown, Figure 2 One first touch electrode 11 can include two first main electrodes 111 and a first connecting part 112 connecting the two first main electrodes 111.

[0062] The second touch electrode 12 includes a second main electrode 121 and a second connecting part 122, in the same second touch electrode 12, two adjacent second main electrodes 121 are electrically connected by the second connecting part 122.

[0063] For example, as shown, Figure 20 One second touch electrode 12 can include two second main electrodes 121 and a second connecting part 122 connecting the two second main electrodes 121.

[0064] As shown, Figure 19 , Figure 2 For Figure 19 A cross-sectional view along the A1A1' tangent line in the first direction Z, the first connecting part 112 overlaps the second touch electrode 12, and the first direction Z is perpendicular to the plane on which the display panel 01 is located.

[0065] For example, the second main electrode 121 and the second connecting part 122 are in the same layer, the first main electrode 111 and the second touch electrode 12 are in the same layer, and the first connecting part 112 and the second touch electrode 12 are in different film layers. That is, the first main electrode 111 and the first connecting part 112 are in different film layers.

[0066] Optionally, the first connecting part 112 is located on the side of the first main electrode 111 away from the light-emitting surface of the display panel 01.

[0067] in combination Figure 20 as shown, Figure 4 for Figure 5A A cross-sectional view along the tangent line A2A2' of FIG. 2B. The display panel 01 further includes a dummy electrode 200 located on the side of the display panel 01 where the display cathode COM faces the light-out surface of the display panel 01. The dummy electrode 200 includes a first dummy electrode 21. A first break D1 is included between the first main electrode 111 and the second touch electrode 12 in the same layer. The first dummy electrode 21 projects onto the first break D1 in the plane of the first main electrode 111 in the first direction Z and overlaps the first main electrode 111 and / or the second touch electrode 12. That is, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first dummy electrode 21 in the first direction Z.

[0068] It should be noted that, Figure 19 only the case where the first dummy electrode 21 overlaps the first main electrode 111 and the second touch electrode 12 is shown.

[0069] In the embodiments of the present application, the first dummy electrode 21 is arranged to cover the first break D1 in the first direction Z. When the display panel 01 displays a picture, the first dummy electrode 21 can shield the light leakage in the first break D1, which is conducive to avoiding the problem of visibility of the first break D1 in the display picture, thereby improving the display quality of the display panel 01.

[0070] At the same time, the first dummy electrode 21 is arranged to overlap the first main electrode 111 and / or the second touch electrode 12 in the first direction Z, which is conducive to avoiding the problem of poor reliability of the first dummy electrode 21 covering the first break D1 due to process fluctuations, and improving the reliability of the first dummy electrode 21 covering the first break D1, thereby further avoiding the problem of visibility of the first break D1 in the display picture.

[0071] Figure 20 for Figure 19 An enlarged view of the Q1 region in FIG. 2B.

[0072] In one technical solution of the embodiments of the present application, as shown in Figure 20 the first dummy electrode 21 includes a first sub-part 21A and a first dummy part 21B connected to each other. The first dummy part 21B is in the same layer as the first main electrode 111 and is located in the first break D1. A first sub-break D11 is included between the first dummy part 21B and the first main electrode 111. A second sub-break D12 is included between the first dummy part 21B and the second touch electrode 12.

[0073] For example, in combination Figure 19 ,Figure 20 and Figure 21 as shown in Figure 2 A2A2' tangent line in A2 is Figure 22 An enlarged schematic of the A2A2' tangent line in A2. The first dummy portion 21B, the first main electrode 111, and the second touch electrode 12 are all grid-shaped. The first sub-discontinuity D11 between the first dummy portion 21B and the first main electrode 111 can be a discontinuity between one wire in the first dummy portion 21B and one wire in the first main electrode 111. The first dummy portion 21B and the first main electrode 111 can include multiple first sub-discontinuities D11. The second sub-discontinuity D12 between the second dummy portion 22B and the second touch electrode 12 can be a discontinuity between one wire in the first dummy portion 21B and one wire in the second touch electrode 12. The first dummy portion 21B and the second touch electrode 12 can include multiple second sub-discontinuities D12.

[0074] The first sub-portion 21A and the first dummy portion 21B are located in different film layers, and along the first direction Z, the first sub-portion 21A covers the first sub-discontinuity D11 and the second sub-discontinuity D12, and the first sub-portion 21A overlaps the first main electrode 111 and / or the second touch electrode 12. That is, in the first direction Z, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first sub-portion 21A.

[0075] In the technical solution, the first dummy portion 21B is arranged in the same layer as the first main electrode 111 and located in the first discontinuity D1 between the first main electrode 111 and the second touch electrode 12. Then, the first dummy portion 21B can fill part of the first discontinuity D1, and the first sub-portion 21A is arranged to cover the first sub-discontinuity D11 between the first dummy portion 21B and the first main electrode 111 and the second sub-discontinuity D12 between the first dummy portion 21B and the second touch electrode 12, so as to realize the coverage of the first dummy electrode 21 on the first discontinuity D1.

[0076] Moreover, the sizes of the first sub-discontinuity D11 and the second sub-discontinuity D12 are smaller than the size of the first discontinuity D1, which is conducive to reducing the process difficulty of the first sub-portion 21A covering the first sub-discontinuity D11 and the second sub-discontinuity D12.

[0077] Optionally, the first sub-portion 21A is in the same layer as the first connecting portion 112. In this way, the first sub-portion 21A can be prepared with the same process and material as the first connecting portion 112, without the need to increase an additional process for preparing the first sub-portion 21A and without the need to increase the thickness of the display panel 01.

[0078] In an implementation form of the technical solution, as Figure 21As shown, the first sub-part 21A and the first dummy part 21B are connected through a first insulating layer JC1, and the first insulating layer JC1 includes a first through hole K1.

[0079] Optionally, as shown in Figure 22 As shown, the display panel 01 further includes a plurality of sub-pixels PX, and the first dummy part 21B includes a plurality of first alpha wires SL1 and a plurality of first beta wires XL1, and the first alpha wires SL1 and the first beta wires XL1 are intersected.

[0080] The plurality of first alpha wires SL1 and the plurality of first beta wires XL1 cross to define at least one first dummy grid WG1, and the projection of the first dummy grid WG1 in the first direction is closed around at least one sub-pixel PX. The first through hole K1 is located at the intersection of the first dummy grid WG1.

[0081] Based on this arrangement, in the first direction, the first dummy part 21B does not overlap with the sub-pixel PX, which is conducive to avoiding the first dummy part 21B from blocking the light emission of the sub-pixel PX. Moreover, the intersection of the first dummy grid WG1 is usually far away from the sub-pixel PX it surrounds, and arranging the first through hole K1 at the intersection of the first dummy grid WG1 is conducive to reducing the impact of the preparation of the first through hole K1 on the sub-pixel PX, thereby reducing the impact of the preparation of the first through hole K1 on the display effect.

[0082] Optionally, as shown in Figure 5A and Figure 7 As shown, Figure 8 is Figure 17 Another enlarged schematic view of the Q1 region in FIG. 1, in the first direction, the first sub-part 21A overlaps with the first dummy part 21B, and the projection of the first sub-part 21A in the plane where the first dummy part 21B is located is located on the first dummy grid WG1. The first sub-part 21A can at least partially overlap with the first dummy part 21B. In this way, on the one hand, the first sub-part 21A does not overlap with the sub-pixel PX in the first direction Z, which is conducive to avoiding the first sub-part 21A from blocking the light emission of the sub-pixel PX; on the other hand, the structural complexity of the first dummy electrode 21 can be reduced, so as to reduce the difficulty of preparation of the first dummy electrode 21.

[0083] For example, in combination with Figure 18 and Figure 19 As shown, Figure 20 is Figure 22 A schematic view of the first sub-part in FIG. 1, the first dummy electrode 21 includes a first sub-part 21A, and the first sub-part 21A is connected with the first dummy part 21B through at least one first through hole K1. In this case, in the first direction, the projection of the first sub-part 21A in the region of the first dummy part 21B can coincide with the first dummy part 21B.

[0084] As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1. Figure 23 and Figure 23 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1. Figure 23 As shown in FIG. 1A, the first sub-portion 21A can be in the shape of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”, or a combination of at least two of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”. Figure 23 As shown in FIG. 1A, the first sub-portion 21A can be in the shape of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”, or a combination of at least two of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”. Figure 23 As shown in FIG. 1A, the first sub-portion 21A can be in the shape of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”, or a combination of at least two of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”.

[0085] It should be noted that, Figure 24 only the case where the first sub-portion 21A is in the shape of “ㄴ” and “ㅡ” and is connected to the first dummy portion 21B through one or two first via holes K1 is shown.

[0086] Figure 24 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1. Figure 25 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1. Figure 25 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1. Figure 25 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B. The first sub-portion 21A is connected to the first dummy portion 21B through at least one first via hole K1.

[0087] In another technical solution of the embodiments of the present application, as shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A is located in a different film layer from the first main electrode 111. Along the first direction Z, the first sub-portion 21A covers the first break D1, and the first sub-portion 21A overlaps the first main electrode 111 and / or the second touch electrode 12. That is, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first sub-portion 21A in the first direction Z. Figure 26 and Figure 26 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A is located in a different film layer from the first main electrode 111. Along the first direction Z, the first sub-portion 21A covers the first break D1, and the first sub-portion 21A overlaps the first main electrode 111 and / or the second touch electrode 12. That is, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first sub-portion 21A in the first direction Z.

[0088] As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A is located in a different film layer from the first main electrode 111. Along the first direction Z, the first sub-portion 21A covers the first break D1, and the first sub-portion 21A overlaps the first main electrode 111 and / or the second touch electrode 12. That is, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first sub-portion 21A in the first direction Z. Figure 25 As shown in FIG. 1A, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A is located in a different film layer from the first main electrode 111. Along the first direction Z, the first sub-portion 21A covers the first break D1, and the first sub-portion 21A overlaps the first main electrode 111 and / or the second touch electrode 12. That is, at least one of the first main electrode 111 and the second touch electrode 12 overlaps the first sub-portion 21A in the first direction Z.

[0089] It should be noted that, Figure 25 only the case where the first sub-portion 21A overlaps the first main electrode 111 and overlaps the second touch electrode 12 is shown, Figure 27 the A2A2' tangent line in FIG. 1A is Figure 27 an enlarged view of the A2A2' tangent line in FIG. 1A.

[0090] In this technical solution, the first dummy electrode 21 is a single-layer structure. By setting the first sub-part 21A in the first dummy electrode 21 to cover the first fracture surface D1, the first dummy electrode 21 covers the first fracture surface D1. Moreover, the single-layer structure of the first dummy electrode 21 helps to reduce the structural complexity of the first dummy electrode 21, thereby reducing the difficulty of fabricating the first dummy electrode 21.

[0091] Optionally, the first sub-part 21A is on the same layer as the first connecting part 112. In this way, the first sub-part 21A can be manufactured using the same process and materials as the first connecting part 112, which eliminates the need for additional processes to manufacture the first sub-part 21A and does not increase the thickness of the display panel 01.

[0092] Optional, such as Figure 25 As shown, the display panel 01 also includes multiple sub-pixels PX. The first sub-part 21A includes multiple second A traces SL2 and multiple second B traces XL2 connected together. The extension directions of the second A traces SL2 and the second B traces XL2 intersect.

[0093] Multiple second traces SL2 and multiple second traces XL2 intersect to define at least one second dummy grid WG2, and the projection of the second dummy grid WG2 in the first direction Z closes around at least one sub-pixel PX.

[0094] Based on this configuration, in the first direction, the first sub-part 21A does not overlap with the sub-pixel PX, that is, the first dummy electrode 21 does not overlap with the sub-pixel PX, which helps to avoid the first dummy electrode 21 blocking the light emitted by the sub-pixel PX.

[0095] In one embodiment of this application, such as Figure 25 , Figure 28 , Figure 28 As shown, the orthographic projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located is a grid, and both the first main electrode 111 and the second touch electrode 12 are grid-shaped.

[0096] by Figure 25 For example, the grid-like projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located, together with the grid-like first main electrode 111 and the second touch electrode 12, can form a grid structure. That is, the whole consisting of the grid-like projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located, together with the grid-like first main electrode 111 and the second touch electrode 12, is still grid-like.

[0097] At a position where the first dummy electrode 21 is projected on a plane where the first main electrode 111 is located, a grid of the grid structure WG can be defined by the wire in the first main electrode 111 and the wire in the first dummy electrode 21 projected on the plane where the first main electrode 111 is located.

[0098] At a position where the second touch electrode 12 is projected on a plane where the first main electrode 111 is located, a grid of the grid structure WG can be defined by the wire in the second touch electrode 12 and the wire in the first dummy electrode 21 projected on the plane where the first main electrode 111 is located.

[0099] Figure 28 An enlarged schematic view of a position where the first dummy electrode is adjacent to the first main electrode is provided for the embodiments of the present application, Figure 25 An enlarged schematic view of a position where the first dummy electrode is adjacent to the second touch electrode is provided for the embodiments of the present application.

[0100] It is shown in Figure 29 and Figure 29 that the projection of the first dummy electrode 21 on a plane where the first main electrode 111 is located includes a plurality of first wires DL1 forming a grid structure, and the plurality of first wires DL1 can cross each other to form a grid shape. The first main electrode 111 includes a plurality of second wires DL2 forming a grid structure, and the plurality of second wires DL2 can cross each other to form a grid shape. The second touch electrode 12 includes a plurality of third wires DL3 forming a grid structure, and the plurality of third wires DL3 can cross each other to form a grid shape.

[0101] It is shown in Figure 25 that in the first direction, the first wire DL1 overlaps the second wire DL2, and the length L1 at which one first wire DL1 overlaps one second wire DL2 is not greater than the side length W1 of one grid in the grid structure, i.e., L1≤W1. Here, the grid with the side length W1 can refer to a grid defined by the first wire DL1 and the second wire DL2 crossing each other.

[0102] It is shown in Figure 29 that in the first direction, the first wire DL1 overlaps the third wire DL3, and the length L2 at which one first wire DL1 overlaps one third wire DL3 is not greater than the side length W2 of one grid in the grid structure, i.e., L2≤W2. Here, the grid with the side length W2 can refer to a grid defined by the first wire DL1 and the third wire DL3 crossing each other.

[0103] That is, when the first dummy electrode 21 overlaps with the first main electrode 111, it can mean that a first trace DL1 in the first dummy electrode 21 overlaps with a second trace DL2 in the first main electrode 111, and the length L1 of the overlap between one first trace DL1 and one second trace DL2 is not greater than the side length W1 of one grid. Of course, there can be multiple first traces DL1 and second traces DL2 corresponding to the overlap.

[0104] When the first dummy electrode 21 overlaps with the second touch electrode 12, it can mean that a first trace DL1 in the first dummy electrode 21 overlaps with a third trace DL3 in the second touch electrode 12, and the length L2 of the overlap between one first trace DL1 and one third trace DL3 is not greater than the side length W2 of one grid. Of course, there can be multiple first traces DL1 and third traces DL3 corresponding to the overlap.

[0105] In an embodiment of the present application, the length L1 of the overlap between one first trace DL1 and one second trace DL2 is within a certain range, and / or the length L2 of the overlap between one first trace DL1 and one third trace DL3 is within a certain range, which is conducive to avoiding excessive overlap between the first dummy electrode 21 and the first main electrode 111, and / or excessive overlap between the first dummy electrode 21 and the second touch electrode 12, thereby avoiding the generation of a large coupling capacitance between the first dummy electrode 21 and the first main electrode 111 and / or the second touch electrode 12, which affects the potential of the first main electrode 111 and / or the second touch electrode 12, and further helps to reduce the influence of the first dummy electrode 21 on touch accuracy.

[0106] Figure 30A For Figure 30B an enlarged schematic view at Q2 in FIG. 1, Figure 30A an enlarged schematic view at Q2 in FIG. 1, Figure 30B a cross-sectional schematic view along A3A3' in FIG. 1.

[0107] In an embodiment of the present application, in combination with Figure 30A , Figure 30B and Figure 30A as shown, between the two adjacent first touch electrodes 11 and the two adjacent second touch electrodes 12, at least one includes a second break D2. That is, the two adjacent first touch electrodes 11 can include a second break D2, and / or the two adjacent second touch electrodes 12 can include a second break D2. Figure 30B An example is shown in which the two adjacent first touch electrodes 11 include a second break D2.

[0108] As shown in Figure 30A , in the first direction Z, the first dummy electrode 21 covers the second break D2.

[0109] Optionally, in the first direction Z, the first dummy electrode 21 overlaps with at least one of the two adjacent first touch electrodes 11 that include the second break D2, to ensure the reliability of the first dummy electrode 21 covering the second break D2. Of course, if the second break D2 is included between two adjacent second touch electrodes 12, the first dummy electrode 21 may also overlap with at least one of the two adjacent second touch electrodes 12 that include the second break D2.

[0110] For example, such as Figure 30B As shown, the portion of the first dummy electrode 21 covering the second fracture D2 is interconnected with the portion covering the first fracture D1.

[0111] For example, the structure of the portion of the first dummy electrode 21 covering the second fracture surface D2 can be the same as the structure of the portion covering the first fracture surface D1. For instance, both the portion of the first dummy electrode 21 covering the second fracture surface D2 and the portion covering the first fracture surface D1 can be a single-layer structure including the first sub-part 21A. Alternatively, both the portion of the first dummy electrode 21 covering the second fracture surface D2 and the portion covering the first fracture surface D1 can be a double-layer structure including the first sub-part 21A and the first dummy part 21B.

[0112] Of course, the structure of the portion of the first dummy electrode 21 covering the second fracture surface D2 can also be different from the structure of the portion covering the first fracture surface D1. For example, the portion of the first dummy electrode 21 covering the first fracture surface D1 can be a double-layer structure, while the portion of the first dummy electrode 21 covering the second fracture surface D2 can be a single-layer structure.

[0113] In this embodiment, the first dummy electrode 21 can also cover the second break D2 in the first direction Z. When the display panel 01 displays a picture, the first dummy electrode 21 can also block the light leakage in the second break D2, which helps to avoid the problem of the visibility of the second break D2 in the display picture, thereby helping to further improve the display quality of the display panel 01.

Figure 31 for Figure 31 A schematic diagram of a cross-section along the tangent line A4A4'. Figure 31 for Figure 30A A schematic diagram of a cross section along the tangent line A4A4'.

[0115] In one embodiment of this application, both the first touch electrode 11 and the second touch electrode 12 are mesh-shaped, combined with Figure 30B ,Figure 30A and Figure 30B or in combination Figure 32 、 Figure 32 、 Figure 5A As shown in and

[0116] It should be noted that, Figure 6A only the case that the third break D3 is included in both the first touch electrode 11 and the second touch electrode 12 is shown.

[0117] Since the first touch electrode 11 and the second touch electrode 12 are both in a grid shape, in combination Figure 7 and Figure 30A As shown in Figure 30B and Figure 1 When the third break D3 is located in the second touch electrode 12, the third break D3 can be a break between one wire and another wire in the second touch electrode 12, the length of the break being greater than the side length of one grid in the second touch electrode 12, and the second touch electrode 12 can include multiple third breaks D3.

[0118] The dummy electrode 200 further includes a second dummy electrode 22, as shown in Figure 2 and Figure 2 In the first direction Z, the second dummy electrode 22 covers the third break D3.

[0119] When the third break D3 is included in both the first touch electrode 11 and the second touch electrode 12, the second dummy electrode 22 covering the third break D3 in the first touch electrode 11 can be separate from the second dummy electrode 22 covering the third break D3 in the second touch electrode 12.

[0120] Optionally, in the first direction Z, the second dummy electrode 22 overlaps at least one of the two wires including the third break D3, to ensure the reliability of the second dummy electrode 22 covering the third break D3.

[0121] In the embodiments of the present application, the third break D3 can reduce the effective area of the first touch electrode 11 and / or the second touch electrode 12, which is conducive to reducing the parasitic capacitance between the touch unit 100 and the display electrode, thereby facilitating the reduction of the load when the display electrode is working. Meanwhile, the second dummy electrode 22 covers the third break D3, so that when the display panel 01 displays a picture, the second dummy electrode 22 can shield the light leakage in the third break D3, which is conducive to avoiding the problem of visibility of the third break D3 in the display picture, thereby facilitating the further improvement of the display quality of the display panel 01.

[0122] In one of the technical solutions of the embodiments of the present application, as shown in Figure 2 and Figure 21 , the second dummy electrode 22 includes a second sub-part 22A and a second dummy part 22B, the second dummy part 22B is in the same layer as the first main electrode 111 and is located in the third break D3.

[0123] As shown in Figure 22 , the second dummy part 22B and the adjacent first touch electrode 11 include a third sub-break D31, and / or as shown in Figure 5A , the second dummy part 22B and the adjacent second touch electrode 12 include a third sub-break D31.

[0124] For example, as shown in Figure 21 , Figure 22 , the second dummy part 22B can be grid-shaped, the third sub-break D31 can be a break between a wire in the second dummy part 22B and a wire in the first touch electrode 11, and the second dummy part 22B and the adjacent first touch electrode 11 can include multiple third sub-breaks D31. Or as shown in Figure 21 , Figure 33 , the third sub-break D31 is a break between a wire in the second dummy part 22B and a wire in the second touch electrode 12, and the second dummy part 22B and the adjacent second touch electrode 12 can include multiple third sub-breaks D31.

[0125] The second sub-part 22A and the second dummy part 22B are located in different film layers, and along the first direction Z, the second sub-part 22A covers the third sub-break D31.

[0126] Optionally, the second sub-part 22A overlaps at least one of the two wires including the third sub-break D31 to ensure the reliability of the second sub-part 22A covering the third sub-break D31.

[0127] In this technical solution, the second dummy part 22B is set on the same layer as the first main electrode 111 and is located in the third break D3 in the first touch electrode 11 and / or the second touch electrode 12. Then the second dummy part 22B can fill part of the third break D3. At the same time, the second sub-part 22A is set to cover the third sub-break D31 between the second dummy part 22B and the first touch electrode 11 and / or the second touch electrode 12, so that the second dummy electrode 22 can cover the third break D3.

[0128] Moreover, the size of the third sub-fracture point D31 will be smaller than the size of the third fracture point D3, which will help reduce the process difficulty of the second sub-section 22A covering the third sub-fracture point D31.

[0129] Optionally, the second sub-part 22A is on the same layer as the first connecting part 112. In this way, the second sub-part 22A can be manufactured using the same process and materials as the first connecting part 112, which eliminates the need for additional processes to manufacture the second sub-part 22A and does not increase the thickness of the display panel 01.

[0130] In one implementation of this technical solution, such as Figure 33 and ​ As shown, a first insulating layer JC is included between the second sub-part 22A and the second dummy part 22B. The first insulating layer JC includes a second through hole K2, and the second sub-part 22A and the second dummy part 22B are connected through the second through hole K2.

[0131] Optional, such as ​ and ​ As shown, the display panel 01 also includes multiple sub-pixels PX, and the second virtual part 22B includes multiple third A traces SL3 and multiple third B traces XL3 connected together. The extension direction of the third A traces SL3 intersects with the extension direction of the third B traces XL3.

[0132] Multiple third-A traces SL3 and multiple third-B traces XL3 intersect to define at least one third dummy grid WG3. The projection of the third dummy grid WG3 in a first direction closes around at least one sub-pixel PX. The second via K2 is located at the intersection of the third dummy grid WG3.

[0133] Based on this arrangement, in the first direction, the second dummy portion 22B does not overlap with the sub-pixel PX, which helps to prevent the second dummy portion 22B from blocking the light emitted by the sub-pixel PX. Furthermore, the intersection of the third dummy grid WG3 is usually far from the sub-pixel PX it surrounds. Placing the second through-hole K2 at the intersection of the third dummy grid WG3 helps to reduce the impact of the fabrication of the second through-hole K2 on the sub-pixel PX, thereby reducing the impact of the fabrication of the second through-hole K2 on the display effect.

[0134] Optional, such as ​ ,​ As shown, in the first direction, the second sub-portion 22A overlaps the second dummy portion 22B, and the projection of the second sub-portion 22A on the plane where the second dummy portion 22B is located is located on the third dummy grid WG3. The second sub-portion 22A can overlap at least part of the second dummy portion 22B. In this way, on the one hand, the second sub-portion 22A does not overlap the sub-pixel PX in the first direction Z, which is conducive to avoiding the second sub-portion 22A from blocking the light emission of the sub-pixel PX; on the other hand, the structural complexity of the second dummy electrode 22 can be reduced, which is conducive to reducing the difficulty of manufacturing the second dummy electrode 22.

[0135] For example, as shown in ​ , ​ and ​ , ​ is another enlarged schematic view of the Q3 region in ​ , ​ is another enlarged schematic view of the Q4 region in ​ , ​ is a schematic view of the second sub-portion in ​ and ​ , the second dummy electrode 22 includes one second sub-portion 22A, and the second sub-portion 22A is connected to the second dummy portion 22B through at least one second through hole K2. In this case, in the first direction Z, the projection of the second sub-portion 22A on the region of the second dummy portion 22B can coincide with the second dummy portion 22B.

[0136] For example, as shown in ​ , ​ and ​ , ​ is a schematic view of the second sub-portion in ​ and ​ , the second dummy electrode 22 includes a plurality of second sub-portions 22A, and one second sub-portion 22A is connected to the second dummy portion 22B through at least one second through hole K2. As shown in ​ , the second sub-portion 22A can be in the shape of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”, or a combination of at least two of “ㅡ”, “ㄴ”, “ㄷ”, “ㅁ”.

[0137] It should be noted that ​ only the case where the second sub-portion 22A is in the shape of “ㄴ” or “ㅡ” and is connected to the second dummy portion 22B through one or two second through holes K2 is shown.

[0139] In another implementation of this technical solution, combined with ​ and ​ As shown, the second sub-part 22A is separate from the second dummy part 22B. That is, the second sub-part 22A and the second dummy part 22B are located in different film layers and are not connected.

[0140] Based on this configuration, the second sub-part 22A and the second dummy part 22B need to be connected by drilling, which helps to simplify the fabrication process of the second dummy electrode 22 and save costs.

[0141] It should be noted that, ​ The second dummy electrode 22 in region Q4 can also be adopted as follows: ​ and ​ The structure shown.

[0143] In another technical solution of this application embodiment, combined with ​ and ​ As shown, the second dummy electrode 22 includes a second sub-part 22A, which is located in a different film layer from the first main electrode 111. Along the first direction Z, the second sub-part 22A covers the third fracture D3.

[0144] Optionally, in the first direction Z, the second sub-section 22A overlaps with at least one of the two traces including the third break D3. This improves the reliability of the second sub-section 22A covering the third break D3.

[0145] In this technical solution, the second dummy electrode 22 has a single-layer structure. By setting the second sub-part 22A in the second dummy electrode 22 to cover the third fracture surface D3, the second dummy electrode 22 covers the third fracture surface D3. Moreover, the single-layer structure of the second dummy electrode 22 helps to reduce the structural complexity of the second dummy electrode 22, thereby reducing the difficulty of fabricating the second dummy electrode 22.

[0146] Optionally, the second sub-part 22A is on the same layer as the first connecting part 112. In this way, the second sub-part 22A can be manufactured using the same process and materials as the first connecting part 112, which eliminates the need for additional processes to manufacture the second sub-part 22A and does not increase the thickness of the display panel 01.

[0147] Optional, such as ​As shown, the display panel 01 further includes a plurality of sub-pixels PX, the second sub-portion 22A includes a plurality of fourth alpha wires SL4 and a plurality of fourth beta wires XL4 connected, and the extension direction of the fourth alpha wires SL4 intersects with the extension direction of the fourth beta wires XL4.

[0148] The plurality of fourth alpha wires SL4 and the plurality of fourth beta wires XL4 cross to define at least one fourth dummy grid WG4, and the projection of the fourth dummy grid WG4 in the first direction is closed to surround the at least one sub-pixel PX.

[0149] Based on this arrangement, in the first direction, the second sub-portion 22A does not overlap with the sub-pixel PX, i.e., the second dummy electrode 22 does not overlap with the sub-pixel PX, which is beneficial to avoid the second dummy electrode 22 from shielding the light emission of the sub-pixel PX.

[0150] It should be noted that, ​ The second dummy electrode 22 in the Q4 region can also adopt the structure as shown in ​ and ​ When the first touch electrode 11 and the second touch electrode 12 both include the third break D3, the structure of the second dummy electrode 22 covering the third break D3 in the first touch electrode 11 can be the same as or different from the structure of the second dummy electrode 22 covering the third break D3 in the second touch electrode 12.

[0152] In an embodiment of the present application, as shown in ​ , ​ and ​ The first main electrode 111 and the second touch electrode 12 further include a fourth break D4, and the length of the fourth break D4 is less than the length of the first break D1.

[0153] For example, as shown in ​ , ​ , ​ and ​ The first main electrode 111 and the second touch electrode 12 are both grid-shaped, the first break D1 is a break between a wire in the first main electrode 111 and a wire in the second touch electrode 12, and the length of the first break D1 can be greater than the side length of one grid in the first main electrode 111 and the second touch electrode 12.

[0154] The fourth fracture D4 is also a fracture between a wire in the first main electrode 111 and a wire in the second touch electrode 12, and the length of the fourth fracture D4 is less than the side length of one grid in the first main electrode 111 and the second touch electrode 12. The fourth fracture D4 and the first fracture D1 can be located at different adjacent positions of the first main electrode 111 and the second touch electrode 12.

[0155] In combination ​ And ​ As shown in FIG. 8, the dummy electrode 200 further includes a third dummy electrode 23, and the third dummy electrode 23 includes a third sub-portion 23A, which is located in a different film layer from the first main electrode 111. Along the first direction Z, the third sub-portion 23A covers the fourth fracture D4 and overlaps the first main electrode 111 and / or the second touch electrode 12.

[0156] It should be noted that, ​ And ​ Only the case where the third sub-portion 23A overlaps the first main electrode 111 and overlaps the second touch electrode 12 is shown.

[0157] In the embodiments of the present application, the third sub-portion 23A is arranged to cover the fourth fracture D4 in the first direction Z, so that when the display panel 01 displays a picture, the third sub-portion 23A can shield the light leakage in the fourth fracture D4, which is conducive to avoiding the problem of visibility of the fourth fracture D4 in the display picture, thereby being conducive to further improving the display quality of the display panel 01.

[0158] At the same time, the third sub-portion 23A is arranged to overlap the first main electrode 111 and / or the second touch electrode 12 in the first direction Z, which is conducive to avoiding the problem of poor reliability of the third sub-portion 23A covering the fourth fracture D4 due to process fluctuations, and is conducive to improving the reliability of the third sub-portion 23A covering the fourth fracture D4.

[0159] Optionally, the third sub-portion 23A is in the same layer as the first connecting portion 112. In this way, the third sub-portion 23A can be prepared with the same process and material as the first connecting portion 112, without the need to add an additional process for preparing the third sub-portion 23A, and without increasing the thickness of the display panel 01.

[0160] Optionally, the third sub-portion 23A is in the same layer as the first connecting portion 112. In this way, the third sub-portion 23A can be prepared with the same process and material as the first connecting portion 112, without the need to add an additional process for preparing the third sub-portion 23A, and without increasing the thickness of the display panel 01.

[0161] ​ For ​ FIG. 8 is another cross-sectional view of the display panel 01 along the A1A1' tangent, ​ FIG. 9 is a partial enlarged view of a fourth sub-portion provided in the embodiments of the present application.

[0165] Further, the fourth sub-portion 24A can extend to the edge of the display area of the display panel 01.

[0166] The fourth sub-portion 24A receives a fixed potential signal. Exemplarily, the fixed potential signal can be a power supply voltage signal, a ground signal, a reset signal or other constant voltage signal.

Therefore, the fourth sub-portion 24 can play a shielding role, which is conducive to reducing the mutual interference between the touch signal and the display signal.

Along the first direction Z, the third sub-portion 23A covers the fourth break D4 and overlaps the first main electrode 111 and / or the second touch electrode 12.

[0171] In combination ​ As shown, in the first sub-portion 21A, the second sub-portion 22A and the third sub-portion 23A, at least one is integrally arranged with the fourth sub-portion 24. That is, at least one of the first sub-portion 21A, the second sub-portion 22A and the third sub-portion 23A is prepared with the fourth sub-portion 24 in the same material and the same process, and is connected with each other.

[0172] For example, the fourth sub-portion 24 can be connected with the second sub-portion 22A and the third sub-portion 23A, and disconnected with the first sub-portion 21A and the first connecting portion 112.

[0176] ​ Another planar schematic view of a display panel is provided in the embodiments of the present application.

[0177] In one embodiment of the present application, as​ As shown, the display panel 01 includes a display area AA and a frame area NA surrounding the display area AA, and the fourth sub-part 24 is located in the display area AA.

[0178] In the display area AA, the fourth sub-part 24 can be connected with the first sub-part 21A, the second sub-part 22A and the third sub-part 23A, and form a full-surface structure in the display area AA except at the position of the first connecting part 112, which is in a grid shape. For convenience of description, the whole formed by connecting the first sub-part 21A, the second sub-part 22A, the third sub-part 23A and the fourth sub-part 24 is collectively referred to as the fourth sub-part 24. ​

The fourth sub-part 24 receives the fixed potential signal through the metal pad layer 300.

[0181] In the embodiments of the present application, the grid-shaped fourth sub-part 24 receives the fixed potential signal through the metal pad layer 300, which can reduce the loss of the fixed potential signal transmission and is beneficial to saving power consumption.

[0183] Optionally, the fixed potential signal line 400 surrounds the display area AA, and the metal pad layer 300 surrounds the fourth sub-part 24. The fixed potential signal line 400 can be electrically connected with the metal pad layer 300 from different sides of the display area AA, so as to further reduce the loss of the fixed potential signal transmission.

[0184] As shown in the example, ​ As shown, the fixed potential signal line 400 can be non-closed around the display area AA, so as to avoid mutual interference between the fixed potential signal line 400 and other wires in the frame area NA.

The fixed potential signal line 400 is located near the edge in the display area AA, and the fixed potential signal line 400 surrounds the fourth sub-portion 24.

[0186] ​ Another planar schematic view of the display panel is provided in an embodiment of the present application.

[0187] In an embodiment of the present application, as shown in ​ The frame area NA includes the first frame area NA1 and the second frame area NA2 located on opposite sides of the display area AA, the first frame area NA1 includes the binding area BQ for binding the control chip (not shown in the figure), and the first frame area NA1 and the second frame area NA2 are arranged along the second direction Y.

[0188] The frame area NA further includes the third frame area NA3 and the fourth frame area NA4 located on opposite sides of the display area AA, the third frame area NA3 and the fourth frame area NA4 are arranged along the third direction X, and the second direction Y intersects the third direction X.

[0189] For example, the second direction Y is the column direction of the display panel 01, and the third direction X is the row direction of the display panel 01. The first frame area NA1 is the "lower" frame of the display panel 01, the second frame area NA2 is the "upper" frame of the display panel 01, the third frame area NA3 is the "left" frame of the display panel 01, and the fourth frame area NA4 is the "right" frame of the display panel 01.

[0190] The display panel 01 further includes the first touch signal line TX and the second touch signal line RX, the first touch signal line TX is electrically connected with the first touch electrode 11 (connection structure not shown), and the second touch signal line RX is electrically connected with the second touch electrode 12 (connection structure not shown).

[0191] Part of the second touch signal line RX extends from the first frame area NA1 to the third frame area NA3, and is electrically connected with the second touch electrode 12 through the third frame NA3. Part of the second touch signal line RX extends from the first frame area NA1 to the fourth frame area NA4, and is electrically connected with the second touch electrode 12 through the fourth frame NA4.

[0192] Optionally, as shown in ​As shown, the first border area NA1 includes a first wiring area B1 and a second wiring area B2 in which the first touch signal line TX is arranged, and the first wiring area B1 and the second wiring area B2 are arranged along the third direction X. In the first touch signal line TX in the first border area NA1, a part of the first touch signal line TX passes through the first wiring area B1, and another part of the first touch signal line TX passes through the second wiring area B2.

[0193] In combination ​ As shown, ​ For ​ A partial enlarged view of the first border area in the first border area, a gap M is included between the first wiring area B1 and the second wiring area B2, and the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the gap M. That is, the connection wire 41 between the fixed potential signal line 400 and the metal pad layer 300 passes through the gap M.

[0194] Based on this arrangement, the connection wire 41 between the fixed potential signal line 400 and the metal pad layer 300 is relatively easy to manufacture, and the arrangement interference between the connection wire 41 and the first touch signal line TX can be reduced.

[0195] It should be noted that in some cases, in the first border area NA1, some wires extending along the third direction X, such as protection lines, virtual lines, etc., are also arranged between the fixed potential signal line 400 and the metal pad layer 300. These wires can be disconnected at the gap M.

[0196] Optionally, in combination ​ And ​ As shown, ​ For ​ A partial enlarged view of the second border area in the first border area, the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the second border area NA2. In the second border area NA2, the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the bridge structure 42.

[0197] The present inventors have found through research that in the second border area NA2, the fixed potential signal line 400 and the metal pad layer 300 are usually provided with a protection line GU extending along the third direction X, and the protection line GU cannot be completely disconnected in the second border area NA2. Therefore, the bridge structure 42 is arranged to cross the protection line GU to realize the electrical connection between the fixed potential signal line 400 and the metal pad layer 300.

[0198] Of course, in the second border area NA2, if other wires extending along the third direction X are also arranged between the fixed potential signal line 400 and the metal pad layer 300, the bridge structure 42 can also cross them.

[0200] In combination ​ As shown, ​ For ​ A partial enlarged view of the first region in the middle, the fixed potential signal line 400 is electrically connected to the metal pad 300 through the first region C1.

[0201] For example, as shown, ​ In the first region C1, the fixed potential signal line 400 is electrically connected to the metal pad 300 through the shield line GU by the cross-bridge structure 42.

[0202] Of course, in the first region C1, if there are other lines extending along the second direction Y between the fixed potential signal line 400 and the metal pad 300, the cross-bridge structure 42 can also cross over them.

[0203] Optionally, as shown, ​ The fourth frame area NA4 includes a fourth wiring area B4 in which the second touch signal line RX is disposed, and a second region C2 located at one side of the fourth wiring area B4, and the fourth wiring area B4 and the second region C2 are arranged along the second direction Y.

[0204] In combination ​ As shown, ​ For ​ A partial enlarged view of the second region in the middle, the fixed potential signal line 400 is electrically connected to the metal pad 300 through the second region C2.

[0205] For example, as shown, ​ In the second region C2, the fixed potential signal line 400 is electrically connected to the metal pad 300 through the shield line GU by the cross-bridge structure 42.

[0206] Of course, in the second region C2, if there are other lines extending along the second direction Y between the fixed potential signal line 400 and the metal pad 300, the cross-bridge structure 42 can also cross over them.

[0207] ​ A partial enlarged view of a first main electrode provided by an embodiment of the present application, ​ A partial enlarged view of a second touch electrode provided by an embodiment of the present application.

[0208] In one embodiment of this application, combined with ​ and ​ As shown, both the first main electrode 111 and the second touch electrode 12 are grid-shaped. The display panel 01 also includes a plurality of sub-pixels PX. Both the first main electrode 111 and the second touch electrode 12 include a sixth A trace SL6 and a sixth B trace XL6 that intersect in their extending directions and are electrically connected. The sixth A trace SL6 and the sixth B trace XL6 intersect to define at least one first grid WK1. The first grid WK1 surrounds at least one sub-pixel PX.

[0209] For example, such as ​ and ​ As shown, a first grid WK1 surrounds a sub-pixel PX.

[0210] The plurality of sub-pixels PX includes a first color sub-pixel PX1 and a second color sub-pixel PX2. The first grid WK1 includes a first sub-grid WK11 surrounding the first color sub-pixel PX1 and a second sub-grid WK12 surrounding the second color sub-pixel PX2. That is, the first grid WK1 surrounding the first color sub-pixel PX1 can be the first sub-grid WK11, and the first grid WK1 surrounding the second color sub-pixel PX2 can be the second sub-grid WK12.

[0211] Optionally, the first color sub-pixel PX1 is a red sub-pixel, and the second color sub-pixel PX2 is a blue sub-pixel. Furthermore, as... ​ and ​ As shown, sub-pixel PX also includes a third color sub-pixel PX3. The third color sub-pixel PX3 is arranged adjacent to the first color sub-pixel PX1 and the second color sub-pixel PX2. The third color sub-pixel PX3 is a green sub-pixel.

[0212] At least a portion of the first sub-mesh WK11 includes a first slit KF1, which may be located on an edge of the first sub-mesh WK11. The length of the first slit KF1 is less than the edge length of the first sub-mesh WK11. Here, the length of the first slit KF1 refers to the length of the first slit KF1 in the direction of its extension along the edge of the first sub-mesh WK11 in which it is located.

[0213] In different first sub-grids WK11, the orientation of the first slits KF1 is the same. Here, the same orientation of the first slits KF1 means that the directions of each first slit KF1 pointing to the first color sub-pixel PX1 surrounded by the first sub-grid WK11 it is located in are parallel to each other.

[0214] The second scribe line KF2 is included in at least part of the second sub-grid WK12, and can be located on an edge of the second sub-grid WK12. The length of the second scribe line KF2 is less than the length of the edge of the second sub-grid WK12. Here, the length of the second scribe line KF2 refers to the length of the second scribe line KF2 in the direction in which the edge of the second sub-grid WK12 is extended.

[0215] In different second sub-grids WK12, the orientations of the second scribe lines KF2 are the same. Here, the orientations of the second scribe lines KF2 being the same means that the directions in which the second scribe lines KF2 point to the second color sub-pixels PX2 around the second sub-grids WK12 are parallel to each other.

[0216] In the embodiments of the present application, the orientations of the first scribe lines KF1 are the same, and the orientations of the second scribe lines KF2 are the same, which is beneficial to improve the problem of observing diagonal lines at a large viewing angle, thereby improving the display quality of the display panel 01.

[0217] Optionally, as shown in ​ and ​ , the orientations of the first scribe lines KF1 and the orientations of the second scribe lines KF2 intersect. That is, the directions in which the first scribe lines KF1 point to the first color sub-pixels PX1 around the first sub-grids WK11 and the directions in which the second scribe lines KF2 point to the second color sub-pixels PX2 around the second sub-grids WK12 intersect with each other.

[0218] Further, the orientations of the first scribe lines KF1 and the orientations of the second scribe lines KF2 are perpendicular.

[0219] Based on this arrangement, it is beneficial to further improve the problem of observing diagonal lines at a large viewing angle.

[0220] It should be noted that in the present application, the extension directions of the first, second, third, fourth, fifth and sixth a-wiring lines SL1, SL2, SL3, SL4, SL5 and SL6 described in each embodiment can be the same; and the extension directions of the first, second, third, fourth, fifth and sixth b-wiring lines XL1, XL2, XL3, XL4, XL5 and XL6 described in each embodiment can be the same.

[0221] In an embodiment of the present application, as shown in ​ and ​ , the first main electrode 111 and the second touch electrode 12 are both grid-shaped, and at least one of the first main electrode 111 and the second touch electrode 12 includes a scribe line KF. The length of the scribe line KF is less than the length of an edge of a grid. ​ The case in which the first main electrode 111 includes a scribe line KF is shown, ​This illustrates the case where the second touch electrode 12 includes a slit KF.

[0222] Combination ​ As shown, ​ This is a partial structural diagram of a display panel provided in an embodiment of the present application. The display panel 01 also includes a light extraction structure MLP, located on the side of the slit KF facing the light-emitting surface of the display panel 01. The projection of the light extraction structure MLP in the first direction Z covers the slit KF.

[0223] The light extraction structure MLP includes a first layer MLP1 and a second layer MLP2 with different refractive indices. The light extraction structure MLP is used to convert large-angle light into small-angle light for emission.

[0224] For example, such as ​ As shown, the first MLP1 layer includes an opening P, which overlaps with the slit KF in the first direction Z. The second MLP2 layer covers the first MLP1 layer, and the refractive index of the second MLP2 layer is greater than that of the first MLP1 layer.

[0225] It is understandable that the second layer MLP2 can fill the opening P of the first layer MLP1.

[0226] In this embodiment, since the refractive index of the first layer MLP1 is less than that of the second layer MLP2, the large-angle light emitted from the slit KF can be converted into smaller-angle light after passing through the light extraction structure MLP and emitted. This can reduce the large-angle light emitted from the slit KF, which helps to alleviate the problem of oblique lines observed at large viewing angles caused by the large-angle light emitted from the slit KF, thereby improving the display quality of the display panel 01.

[0227] In one embodiment of this application, such as ​ and ​ As shown, both the first main electrode 111 and the second touch electrode 12 are grid-shaped. At least one of the first main electrode 111 and the second touch electrode 12 includes a slit KF, the length of which is less than the side length of a grid. ​ This diagram illustrates the case where the first main electrode 111 includes a slit KF. ​ This illustrates the case where the second touch electrode 12 includes a slit KF.

[0228] like ​ As shown, ​ This is a partial structural schematic diagram of another display panel provided in an embodiment of the present application. The display panel 01 also includes a microlens structure OC, which covers the slit KF in the first direction Z.

[0229] Exemplarily, the microlens structure OC protrudes away from the side of the scribe KF. The display panel 01 further includes a second insulating layer JC2 covering the microlens structure OC, and a refractive index of the microlens structure OC is greater than a refractive index of the second insulating layer JC2.

[0230] In the embodiment of the present application, the large-angle light emitted from the scribe KF can be converted into light with a smaller angle after passing through the microlens structure OC and being emitted, which can reduce the large-angle light emitted from the scribe KF, and is conducive to alleviating the problem that the scribe KF causes diagonal lines to be observed at a large viewing angle, thereby being conducive to improving the display quality of the display panel 01.

[0231] In one embodiment of the present application, as shown in ​ , ​ and ​ , the first touch electrode 11, the second touch electrode 12 and the first dummy electrode 21 are all grid-shaped, and no scribe is arranged in the grid of the first touch electrode 11, the second touch electrode 12 and the first dummy electrode 21. Here, the scribe refers to a break with a length less than the length of one grid side, such as the scribe KF in ​ and ​ .

[0232] In the embodiment of the present application, no scribe is arranged in the grid of the first touch electrode 11, the second touch electrode 12 and the first dummy electrode 21, which is conducive to avoiding the large viewing angle stripe problem caused by the scribe, thereby being conducive to further improving the display quality of the display panel 01.

[0233] The embodiment of the present application provides a display panel 01, as shown in ​ , the display panel 01 includes a plurality of touch units 100, each touch unit 100 includes a first touch electrode 11 and a second touch electrode 12, and the first touch electrode 11 is electrically insulated from the second touch electrode 12.

[0234] In the display panel 01, the touch units 100 can be arranged in a row direction and a column direction, in a plurality of touch units 100 arranged in the column direction, the first touch electrodes 11 in each touch unit 100 can be electrically connected in sequence; in a plurality of touch units 100 arranged in the row direction, the second touch electrodes 12 in each touch unit 100 can be electrically connected in sequence. When a user touches the display panel 01, the control system can calculate the coordinates of the touch point according to the mutual capacitance between the first touch electrode 11 and the second touch electrode 12 in the touch unit 100.

[0235] As shown in ​ , the first touch electrode 11 includes a first main electrode 111 and a first connecting portion 112, and in the same first touch electrode 11, two adjacent first main electrodes 111 are electrically connected through the first connecting portion 112.

[0236] As shown in ​ For example, one first touch electrode 11 can include two first body electrodes 111 and a first connecting part 112 connecting the two first body electrodes 111.

[0237] The second touch electrode 12 includes a second body electrode 121 and a second connecting part 122. In the same second touch electrode 12, two adjacent second body electrodes 121 are electrically connected by the second connecting part 122.

[0238] As shown in ​ For example, one second touch electrode 12 can include two second body electrodes 121 and a second connecting part 122 connecting the two second body electrodes 121.

[0239] In combination with ​ and ​ , in the first direction Z, the first connecting part 112 overlaps the second touch electrode 12.

[0240] For example, the second body electrode 121 and the second connecting part 122 are in the same layer, the first body electrode 111 and the second touch electrode 12 are in the same layer, and the first connecting part 112 and the second touch electrode 12 are in different film layers. That is, the first body electrode 111 and the first connecting part 112 are in different film layers.

[0241] The first connecting part 112 is located between the first body electrode 111 and the display cathode COM. The display panel 01 further includes a fourth sub-part 24, which is in the same layer as the first connecting part 112, and the fourth sub-part 24 is in a grid shape.

[0242] For example, in combination with ​ and ​ , ​ As shown in , the first body electrode 111 and the second touch electrode 12 are both in a grid shape, and along the first direction Z, the grid-shaped projection of the fourth sub-part 24 at least partially overlaps the grid-shaped projection of the first body electrode 111 and the second touch electrode 12. The first direction Z is perpendicular to the plane on which the display panel 01 is located. It should be noted that ​ Only the case where the fourth sub-part 24 overlaps the first body electrode 111 is shown.

[0243] Among them, the fourth sub-part 24 receives a fixed potential signal.

[0244] In the embodiments of the present application, the fourth sub-part 24 is located between the first main electrode 111 and the display cathode COM of the display panel 01, and the fourth sub-part 24 receives a fixed potential signal, so that the fourth sub-part 24 can play a shielding role, which is conducive to reducing the mutual interference between the touch signal and the display signal. Moreover, the grid-shaped fourth sub-part 24 can not overlap with the sub-pixels in the display panel 01, so as to avoid affecting the normal display of the display panel 01 by the fourth sub-part 24.

[0245] For example, the display panel 01 provided by the present application can further include a polaroid, which is arranged on the side of the touch unit 100 facing the light-emitting surface of the display panel 01.

[0246] For example, the display panel 01 provided by the present application can further include a color resistance layer, which is arranged on the side of the touch unit 100 facing the light-emitting surface of the display panel 01.

[0250] At the same time, the first dummy electrode 21 is arranged to overlap with the first main electrode 111 and / or the second touch electrode 12 in the first direction Z, which is conducive to avoiding the problem of poor reliability of the first dummy electrode 21 covering the first break D1 due to process fluctuations, and improving the reliability of the first dummy electrode 21 covering the first break D1, thereby further avoiding the problem of visibility of the first break D1 in the display picture.
