[0017] FIG. 1 A planar schematic diagram of a display panel provided in an embodiment of the present application is shown, FIG. 2 An enlarged schematic diagram of a touch unit provided in an embodiment of the present application is shown.

[0018] An embodiment of the present application provides a display panel 01, which is shown in combination with FIG. 1 and FIG. 2 As 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, and the first touch electrode 11 is electrically insulated from the second touch electrode 12.

[0019] In the display panel 01, touch units 100 can be arranged in an array along the row and column directions. Among the multiple touch units 100 arranged along the column direction, the first touch electrodes 11 in each touch unit 100 can be electrically connected sequentially; among the multiple touch units 100 arranged along the row direction, the second touch electrodes 12 in each touch unit 100 can be electrically connected sequentially. When a user touches the display panel 01, the control system can calculate the coordinates of the touch point based on the mutual capacitance between the first touch electrodes 11 and the second touch electrodes 12 in the touch units 100.

[0020] 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 through the first connecting part 112.

[0021] For example, such as FIG. 2 As shown, a first touch electrode 11 may include two first main electrodes 111 and a first connecting portion 112 connecting the two first main electrodes 111.

[0022] The second touch electrode 12 includes a second main electrode 121 and a second connecting portion 122. In the same second touch electrode 12, two adjacent second main electrodes 121 are electrically connected through the second connecting portion 122.

[0023] For example, such as FIG. 2 As shown, a second touch electrode 12 may include two second main electrodes 121 and a second connecting portion 122 connecting the two second main electrodes 121.

[0024] like FIG. 3 As shown, FIG. 3 for FIG. 2 A cross-sectional schematic diagram along the tangent line A1A1' shows that, in the first direction Z, the first connecting part 112 overlaps with the second touch electrode 12, and the first direction Z is perpendicular to the plane where the display panel 01 is located.

[0025] For example, the second main electrode 121 and the second connecting portion 122 are on the same layer, the first main electrode 111 and the second touch electrode 12 are on the same layer, and the first connecting portion 112 and the second touch electrode 12 are located on different film layers. That is, the first main electrode 111 and the first connecting portion 112 are located on different film layers.

[0026] Optionally, the first connection portion 112 is located on the side of the first main electrode 111 away from the light-emitting surface of the display panel 01.

[0027] Combination FIG. 1-4B As shown, FIG. 4A-4B for FIG. 2A cross-sectional view along the A2A2' tangent line. The display panel 01 further includes a dummy electrode 200 located on the side of the display panel 01 facing the display cathode COM toward the light-emitting surface of the display panel 01, the dummy electrode 200 includes a first dummy electrode 21, and a first break D1 is included between the first main electrode 111 and the second touch electrode 12 in the same layer. In the first direction Z, the projection of the first dummy electrode 21 on the plane where the first main electrode 111 is located covers the first break D1 and 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 dummy electrode 21.

[0028] It should be noted that, FIG. 4A-4B Only the case where the first dummy electrode 21 overlaps the first main electrode 111 and the second touch electrode 12 is shown.

[0029] 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, so that 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 beneficial to avoid the problem of visibility of the first break D1 in the display picture, thereby improving the display quality of the display panel 01.

[0030] 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 beneficial to avoid the problem of poor reliability of the first dummy electrode 21 covering the first break D1 due to process fluctuations, and is beneficial to improve 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.

[0031] FIG. 5A For FIG. 2 An enlarged view of the Q1 region.

[0032] In one technical solution of the embodiments of the present application, as shown in FIG. 4A-4B , 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. The first dummy part 21B and the first main electrode 111 include a first sub-break D11, and the first dummy part 21B and the second touch electrode 12 include a second sub-break D12.

[0033] For example, as shown in FIG. 2 , FIG. 4A-4B and FIG. 5A , the A2A2' tangent line in FIG. 5A is FIG. 2An enlarged schematic view of the tangent of A2A2'. The first dummy part 21B, the first main electrode 111, and the second touch electrode 12 are all grid-shaped. The first sub-break D11 between the first dummy part 21B and the first main electrode 111 can be a break between a wire in the first dummy part 21B and a wire in the first main electrode 111. The first dummy part 21B and the first main electrode 111 can include multiple first sub-breaks D11. The second sub-break D12 between the second dummy part 22B and the second touch electrode 12 can be a break between a wire in the first dummy part 21B and a wire in the second touch electrode 12. The first dummy part 21B and the second touch electrode 12 can include multiple second sub-breaks D12.

[0034] The first sub-part 21A and the first dummy part 21B are located in different film layers. In the first direction Z, the first sub-part 21A covers the first sub-break D11 and the second sub-break D12, and the first sub-part 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-part 21A.

[0035] In the technical solution, the first dummy part 21B is arranged in the same layer as the first main electrode 111 and located in the first break D1 between the first main electrode 111 and the second touch electrode 12. Then, the first dummy part 21B can fill part of the first break D1, and the first sub-part 21A is arranged to cover the first sub-break D11 between the first dummy part 21B and the first main electrode 111 and the second sub-break D12 between the first dummy part 21B and the second touch electrode 12. Thus, the first dummy electrode 21 can cover the first break D1.

[0036] Moreover, the sizes of the first sub-break D11 and the second sub-break D12 are smaller than the size of the first break D1, which is conducive to reducing the process difficulty of covering the first sub-break D11 and the second sub-break D12 by the first sub-part 21A.

[0037] Optionally, the first sub-part 21A is in the same layer as the first connection part 112. In this way, the first sub-part 21A can be prepared by the same process and the same material as the first connection part 112, without the need to increase an additional process for preparing the first sub-part 21A and without the need to increase the thickness of the display panel 01.

[0038] In an implementation form of the technical solution, as shown in FIG. 4A The first sub-part 21A and the first dummy part 21B include a first insulating layer JC1, and the first insulating layer JC1 includes a first through hole K1. The first sub-part 21A and the first dummy part 21B are connected through the first through hole K1.

[0039] Optionally, as shown in FIG. 5AAs shown, the display panel 01 further includes a plurality of sub-pixels PX, the first dummy part 21B includes a plurality of first alpha traces SL1 and a plurality of first beta traces XL1 connected with each other, and the first alpha traces SL1 intersect with the extension direction of the first beta traces XL1.

[0040] The plurality of first alpha traces SL1 and the plurality of first beta traces 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 to surround at least one sub-pixel PX. The first via K1 is located at the intersection of the first dummy grid WG1.

[0041] 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 the first via K1 is arranged at the intersection of the first dummy grid WG1, which is conducive to reducing the influence of the preparation of the first via K1 on the sub-pixel PX, thereby reducing the influence of the preparation of the first via K1 on the display effect.

[0042] Optionally, as shown in FIG. 5A and FIG. 6A , FIG. 6A is FIG. 2 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.

[0043] Exemplarily, in combination with FIG. 6A and FIG. 6B , FIG. 6B is FIG. 6A 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 via K1. In this case, in the first direction, the projection of the region of the first sub-part 21A in the first direction can coincide with the first dummy part 21B.

[0044] Exemplarily, in combination with FIG. 5A and FIG. 5B , FIG. 5B is FIG. 5AA schematic view of one of the first sub-sections, the first dummy electrode 21 comprises a plurality of first sub-sections 21A, one of the first sub-sections 21A is connected to the first dummy section 21B through at least one first via hole K1. As shown in FIG. 5B , the first sub-section 21A can be in the form of at least two of the following: a “ ” shape, a “ ” shape, a “ ” shape, a “ ” shape, a “ ” shape, a “ ” shape, a “ ” shape, a “ ” shape.

[0045] It should be noted that FIG. 5B only the cases where the first sub-section 21A is in the form of a “ ” shape and a “ ” shape and is connected to the first dummy section 21B through one or two first via holes K1 are shown.

[0046] FIG. 7 is another enlarged schematic view of the Q1 region in FIG. 2 , and FIG. 8 is a cross-sectional schematic view along the A2A2’ line in FIG. 7 .

[0047] In another technical solution of the embodiments of the present application, in combination with FIG. 7 and FIG. 8 , the first dummy electrode 21 comprises a first sub-section 21A, the first sub-section 21A is located in a different film layer from the first main electrode 111. Along the first direction Z, the first sub-section 21A covers the first fracture D1, and the first sub-section 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-section 21A.

[0048] For example, as shown in FIG. 8 , the first sub-section 21A, the first main electrode 111, and the second touch electrode 12 are all in the form of a grid, the overlap of the first sub-section 21A and the first main electrode 111 means that one wire in the first sub-section 21A overlaps one wire in the first main electrode 111. The overlap of the first sub-section 21A and the second touch electrode 12 means that one wire in the first sub-section 21A overlaps one wire in the second touch electrode 12.

[0049] It should be noted that FIG. 8 only the cases where the first sub-section 21A overlaps the first main electrode 111 and overlaps the second touch electrode 12 are shown, FIG. 8 the A2A2’ line in isFIG. 2 An enlarged illustration of the tangent line A2A2' in the middle.

[0050] 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.

[0051] 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.

[0052] Optional, such as FIG. 7 As shown, the display panel 01 also includes multiple sub-pixels PX, and the first sub-part 21A includes multiple second A traces SL2 and multiple second B traces XL2 connected together, with the extension directions of the second A traces SL2 and the second B traces XL2 intersecting.

[0053] 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.

[0054] 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.

[0055] In one embodiment of this application, such as FIG. 5A , FIG. 6A , FIG. 7 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.

[0056] by FIG. 7 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.

[0057] At the position of the first main electrode 111 near the orthographic projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located, a grid in the grid structure WG can be defined by the intersection of the traces in the first main electrode 111 and the traces of the first dummy electrode 21 onto the orthographic projection of the plane where the first main electrode 111 is located.

[0058] At the position of the second touch electrode 12 near the orthographic projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located, a grid of the grid structure WG can be defined by the intersection of the traces in the second touch electrode 12 and the traces in the orthographic projection of the first dummy electrode 21 onto the plane where the first main electrode 111 is located.

[0059] FIG. 9A This is an enlarged schematic diagram of the area adjacent to the first dummy electrode and the first main electrode, provided in an embodiment of this application. FIG. 9B This is an enlarged schematic diagram of the area adjacent to the first dummy electrode and the second touch electrode, provided in an embodiment of this application.

[0060] Combination FIG. 9A and FIG. 9B As shown, the orthographic projection of the first dummy electrode 21 onto the plane of the first main electrode 111 includes multiple first traces DL1 forming a grid structure, and these multiple first traces DL1 can intersect to form a grid. The first main electrode 111 includes multiple second traces DL2 forming a grid structure, and these multiple second traces DL2 can intersect to form a grid. The second touch electrode 12 includes multiple third traces DL3 forming a grid structure, and these multiple third traces DL3 can intersect to form a grid.

[0061] Among them, such as FIG. 9A As shown, in the first direction, the first trace DL1 and the second trace DL2 overlap. The length L1 of the overlap between the first trace DL1 and the second trace DL2 is not greater than the side length W1 of a grid in the mesh structure, i.e., L1≤W1. Here, a grid with a side length of W1 can refer to a grid defined by the intersection of the first trace DL1 and the second trace DL2.

[0062] And / or, such as FIG. 9B As shown, in the first direction, the first trace DL1 and the third trace DL3 overlap. The length L2 of the overlap between the first trace DL1 and the third trace DL3 is not greater than the side length W2 of a grid in the mesh structure, i.e., L2 ≤ W2. Here, a grid with a side length of W2 can refer to a grid defined by the intersection of the first trace DL1 and the third trace DL3.

[0063] 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.

[0064] 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.

[0065] 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.

[0067] In an embodiment of the present application, in combination with FIG. 2 , FIG. 10 and FIG. 11 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. FIG. 2 An example is shown in which the two adjacent first touch electrodes 11 include a second break D2.

[0068] As shown in FIG. 11 , in the first direction Z, the first dummy electrode 21 covers the second break D2.

[0069] 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.

[0070] For example, such as FIG. 2 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.

[0071] 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.

[0072] 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.

[0073] 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.

FIG. 13A for FIG. 12A A schematic diagram of a cross-section along the tangent line A4A4'. FIG. 13B for FIG. 12B A schematic diagram of a cross section along the tangent line A4A4'.

[0075] In one embodiment of this application, both the first touch electrode 11 and the second touch electrode 12 are mesh-shaped, combined with FIG. 2 ,FIG. 12A and FIG. 13A or in combination FIG. 2 、 FIG. 12B 、 FIG. 13B As shown in and

[0076] It should be noted that, FIG. 2 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.

[0077] Since the first touch electrode 11 and the second touch electrode 12 are both in a grid shape, in combination FIG. 12A and FIG. 13A As shown in FIG. 12B and FIG. 13B 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.

[0078] The dummy electrode 200 further includes a second dummy electrode 22, as shown in FIG. 13A and FIG. 13B In the first direction Z, the second dummy electrode 22 covers the third break D3.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] In one of the technical solutions of the embodiments of the present application, as shown in FIG. 13A and FIG. 13B , 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.

[0083] As shown in FIG. 13A , the second dummy part 22B and the adjacent first touch electrode 11 include a third sub-break D31, and / or as shown in FIG. 13B , the second dummy part 22B and the adjacent second touch electrode 12 include a third sub-break D31.

[0084] For example, as shown in FIG. 12A , FIG. 13A , 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 FIG. 12B , FIG. 13B , 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.

[0085] 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.

[0086] 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.

[0087] In the technical solution, the second dummy part 22B is arranged in the third break D3 in the first touch electrode 11 and / or the second touch electrode 12 and is in the same layer as the first main electrode 111, so that the second dummy part 22B can fill part of the third break D3, and the second sub part 22A is arranged 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 as to realize the coverage of the second dummy electrode 22B on the third break D3.

[0088] In addition, the third sub break D31 has a size smaller than that of the third break D3, which is beneficial to reduce the process difficulty of the second sub part 22A covering the third sub break D31.

[0089] Optionally, the second sub part 22A is in the same layer as the first connecting part 112. In this way, the second sub part 22A can be prepared by the same process and the same material as the first connecting part 112, without the need to increase an additional process for preparing the second sub part 22A and without the increase of the thickness of the display panel 01.

[0090] In an implementation form of the technical solution, as shown in FIG. 13A and FIG. 13B , the second sub part 22A and the second dummy part 22B include a first insulating layer JC, 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.

[0091] Optionally, as shown in FIG. 12A and FIG. 12B , the display panel 01 further includes a plurality of sub-pixels PX, the second dummy part 22B includes a plurality of third alpha wires SL3 and a plurality of third beta wires XL3 connected to each other, and the extension direction of the third alpha wires SL3 intersects with the extension direction of the third beta wires XL3.

[0092] The plurality of third alpha wires SL3 and the plurality of third beta wires XL3 intersect to define at least one third dummy grid WG3, and a projection of the third dummy grid WG3 in the first direction is closed to surround at least one sub-pixel PX. The second through hole K2 is located at an intersection point of the third dummy grid WG3.

[0093] Based on this arrangement, in the first direction, the second dummy part 22B does not overlap with the sub-pixel PX, which is beneficial to avoid the second dummy part 22B from blocking the light emission of the sub-pixel PX. In addition, the intersection point of the third dummy grid WG3 is usually far away from the sub-pixel PX surrounded thereby, and the second through hole K2 is arranged at the intersection point of the third dummy grid WG3, which is beneficial to reduce the influence of the preparation of the second through hole K2 on the sub-pixel PX, and thus is beneficial to reduce the influence of the preparation of the second through hole K2 on the display effect.

[0094] Optionally, as shown in FIG. 12A ,FIG. 12B 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.

[0095] For example, as shown in FIG. 14A , FIG. 14B and FIG. 14C , FIG. 14A is another enlarged schematic view of the Q3 region in FIG. 2 , FIG. 14B is another enlarged schematic view of the Q4 region in FIG. 2 , FIG. 14C is a schematic view of the second sub-portion in FIG. 14A and FIG. 14B . 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.

[0096] For example, as shown in FIG. 12A , FIG. 12B and FIG. 12C , FIG. 12C is a schematic view of the second sub-portion in FIG. 12A and FIG. 12B . 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 FIG. 12C , the second sub-portion 22A can be in the form of at least two of the following: “ ”, “ ”, “ ”, “ ”, “ ”, “ ”, “ ”, “ ”.

[0097] It should be noted that FIG. 12C only the second sub-portion 22A is shown in the form of “ ”, “ The second dummy electrode 22 is connected with the second dummy part 22B through one or two second through holes K2.

That is, the second dummy electrode 22 and the second dummy part 22B are located in different film layers, and the second dummy electrode 22 is not connected with the second dummy part 22B.

[0100] Based on the arrangement, the second dummy electrode 22 and the second dummy part 22B need to be connected through punching, which is beneficial to simplify the preparation process of the second dummy electrode 22 and save cost.

[0101] It should be noted that, FIG. 2 The second dummy electrode 22 in the Q4 region can also adopt the structure as shown in FIG. 15 and FIG. 16 .

Moreover, the second dummy electrode 22 is a single-layer structure, which is conducive to reducing the structural complexity of the second dummy electrode 22, thereby facilitating the preparation difficulty of the second dummy electrode 22.

In this way, the second sub portion 22A can be prepared by the same process and the same material as the first connecting portion 112, without the need to increase an additional process for preparing the second sub portion 22A, and without increasing the thickness of the display panel 01.

[0109] 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 at least one sub-pixel PX.

[0110] Based on this arrangement, in the first direction, the second sub portion 22A does not overlap the sub-pixel PX, that is, the second dummy electrode 22 does not overlap the sub-pixel PX, which is conducive to avoiding the second dummy electrode 22 from blocking the light emission of the sub-pixel PX.

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 process, and is connected to each other.

[0133] For example, the fourth sub-portion 24 can be connected to the second sub-portion 22A and the third sub-portion 23A, and disconnected from the first sub-portion 21A and the first connecting portion 112.

[0134] For example, the fourth sub-section 24 can be connected with the third sub-section 23A, and disconnected with the first sub-section 21A, the second sub-section 22A and the first connecting section 112.

[0137] FIG. 23 Another schematic plan view of a display panel is provided in the embodiment of the present application.

[0138] In one embodiment of the present application, as shown in FIG. 23 , the display panel 01 includes a display area AA and a frame area NA surrounding the display area AA, and the fourth sub-section 24 is located in the display area AA.

[0139] In the display area AA, the fourth sub-section 24 can be connected with the first sub-section 21A, the second sub-section 22A and the third sub-section 23A, and form a full-area structure in the display area AA except the position of the first connecting section 112, and the full-area structure is in a grid shape. For convenience of description, in FIG. 23 , the whole formed by the mutual connection of the first sub-section 21A, the second sub-section 22A, the third sub-section 23A and the fourth sub-section 24 is collectively referred to as the fourth sub-section 24.

[0140] The fourth sub-section 24 includes a plurality of fifth alpha wires SL5 and a plurality of fifth beta wires XL5 electrically connected, and the extension direction of the fifth alpha wires SL5 intersects with the extension direction of the fifth beta wires XL5.

The fixed potential signal line 400 can be located in the bezel area NA, and the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the bezel area NA.

[0144] Optionally, the fixed potential signal line 400 surrounds the display area AA, and the metal pad 300 surrounds the fourth sub-section 24.

[0191] In an embodiment of the present application, the large-angle light rays emitted from the kerf KF can be converted into light of a smaller angle and emitted after passing through the microlens structure OC, which can reduce the large-angle light emitted from the kerf KF, and is conducive to alleviating the problem that the kerf 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.
