[0057] Figure 1 A schematic plan view of a display panel provided in an embodiment of the present application, Figure 2 An enlarged schematic diagram of a touch unit provided in an embodiment of the present application.

[0058] The present application embodiment provides a display panel 01, combined with Figure 1 and Figure 2As shown, the display panel 01 includes a plurality of touch control units 100 . The touch control unit 100 includes a first touch control electrode 11 and a second touch control electrode 12 . The first touch control electrode 11 is electrically insulated from the second touch control electrode 12 .

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

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

[0061] For example, Figure 2 As shown, one first touch electrode 11 may include two first main electrodes 111 and a first connecting portion 112 connecting the two first main electrodes 111 .

[0062] 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 via the second connecting portion 122 .

[0063] For example, Figure 2 As shown, one second touch electrode 12 may include two second main electrodes 121 and a second connecting portion 122 connecting the two second main electrodes 121 .

[0064] like Figure 3 As shown, Figure 3 for Figure 2 A cross-sectional schematic diagram along the A1A1′ cut line in FIG. 1 shows that in a first direction Z, the first connection portion 112 overlaps with the second touch electrode 12 . The first direction Z is perpendicular to the plane where the display panel 01 is located.

[0065] Exemplarily, the second main electrode 121 and the second connecting portion 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 portion 112 and the second touch electrode 12 are in different film layers. That is, the first main electrode 111 and the first connecting portion 112 are in different film layers.

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

[0067] Combination Figure 1-Figure 4 As shown, Figure 4 for Figure 2 A cross-sectional schematic diagram along the A2A2' cut line in FIG. The display panel 01 further includes a dummy electrode 200, which is located on the side of the display cathode COM of the display panel 01 facing the light-emitting surface of the display panel 01, and 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 of the same layer, and along 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 with 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 with the first dummy electrode 21.

[0068] It should be noted that Figure 4 It only schematically illustrates the situation that the first dummy electrode 21 overlaps with the first main electrode 111 and the second touch electrode 12 .

[0069] In the embodiment of the present application, a first dummy electrode 21 is provided to cover the first break D1 in the first direction Z. When the display panel 01 displays an image, the first dummy electrode 21 can block light leakage in the first break D1, which is beneficial to avoid the visibility problem of the first break D1 in the display image, thereby helping to improve the display quality of the display panel 01.

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

[0071] Figure 5A for Figure 2 An enlarged schematic diagram of the Q1 region.

[0072] In a technical solution of an embodiment of the present application, Figure 4 As shown, the first dummy electrode 21 includes a first sub-portion 21A and a first dummy portion 21B connected to each other. The first dummy portion 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 portion 21B and the first main electrode 111, and a second sub-break D12 is included between the first dummy portion 21B and the second touch electrode 12.

[0073] Exemplary, combined Figure 2 , Figure 4 and Figure 5A As shown, Figure 5A The tangent line A2A2' in Figure 2 An enlarged schematic diagram of the tangent line A2A2' in the figure. The first dummy part 21B, the first main electrode 111, and the second touch electrode 12 are all in a grid shape. The first sub-break D11 between the first dummy part 21B and the first main electrode 111 can be a break between a line in the first dummy part 21B and a line 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 21B and the second touch electrode 12 can be a break between a line in the first dummy part 21B and a line in the second touch electrode 12. The first dummy part 21B and the second touch electrode 12 can include multiple second sub-breaks 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-break D11 and the second sub-break D12, and the first sub-portion 21A overlaps with 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 with the first sub-portion 21A.

[0075] In the present technical solution, the first dummy portion 21B is arranged on the same layer as the first main electrode 111 and is located in the first break D1 between the first main electrode 111 and the second touch electrode 12. The first dummy portion 21B can fill part of the first break D1. At the same time, the first sub-portion 21A is arranged to cover the first sub-break D11 between the first dummy portion 21B and the first main electrode 111 and the second sub-break D12 between the first dummy portion 21B and the second touch electrode 12, thereby achieving the covering of the first break D1 by the first dummy electrode 21.

[0076] 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 beneficial to reduce the difficulty of the process of the first sub-portion 21A covering the first sub-break D11 and the second sub-break 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 adding an additional process for preparing the first sub-portion 21A and without increasing the thickness of the display panel 01.

[0078] In one implementation of this technical solution, Figure 4As shown, a first insulating layer JC1 is included between the first sub-portion 21A and the first dummy portion 21B, the first insulating layer JC1 includes a first through hole K1, and the first sub-portion 21A and the first dummy portion 21B are connected through the first through hole K1.

[0079] Optional, such as Figure 5A As shown, the display panel 01 further includes a plurality of sub-pixels PX, and the first dummy portion 21B includes a plurality of first A wiring lines SL1 and a plurality of first B wiring lines XL1 connected to each other, and the extension direction of the first A wiring line SL1 intersects with the extension direction of the first B wiring line XL1.

[0080] The plurality of first A wiring lines SL1 and the plurality of first B wiring lines XL1 intersect to define at least one first dummy grid WG1, and the projection of the first dummy grid WG1 in the first direction encloses 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 portion 21B does not overlap with the sub-pixel PX, which helps to prevent the first dummy portion 21B from blocking the light output 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 through hole K1 is arranged at the intersection of the first dummy grid WG1, which helps to reduce the influence of the preparation of the first through hole K1 on the sub-pixel PX, thereby helping to reduce the influence of the preparation of the first through hole K1 on the display effect.

[0082] Optional, such as Figure 5A and Fig. 6A As shown, Fig. 6A for Figure 2 Another enlarged schematic diagram of the Q1 region, in the first direction, the first sub-portion 21A overlaps with the first dummy portion 21B, and the projection of the first sub-portion 21A on the plane where the first dummy portion 21B is located is located on the first dummy grid WG1. The first sub-portion 21A can overlap with at least part of the first dummy portion 21B. In this way, on the one hand, the first sub-portion 21A does not overlap with the sub-pixel PX in the first direction Z, which is conducive to preventing the first sub-portion 21A from blocking the light output 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 preparing the first dummy electrode 21.

[0083] Exemplary, combined Fig. 6A and Figure 6B As shown, Figure 6B for Fig. 6A A schematic diagram of the first sub-portion in the embodiment of the present invention, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A is connected to the first dummy portion 21B through at least one first through hole K1. In this case, in the first direction, the projection of the first sub-portion 21A in the area of ​​the first dummy portion 21B can overlap with the first dummy portion 21B.

[0084] Exemplary, combined Figure 5A and Figure 5B As shown, Figure 5B for Figure 5A A schematic diagram of the first sub-portion in FIG. 2 , the first dummy electrode 21 includes a plurality of first sub-portions 21A, and one first sub-portion 21A is connected to the first dummy portion 21B through at least one first through hole K1. Figure 5B As shown, the first sub-section 21A may be in the shape of a “-” or Font or Font or Font or "-" font, Font, Font, A combination of at least two of the fonts.

[0085] It should be noted that Figure 5B It only shows that the first sub-section 21A is The case where the first dummy portion 21B is connected to the first dummy portion 21B through one or two first through holes K1.

[0086] Figure 7 for Figure 2 Another enlarged schematic diagram of the middle Q1 area, Figure 8 for Figure 7 A schematic cross-sectional view along the A2A2' tangent line.

[0087] In another technical solution of the embodiment of the present application, combined with Figure 7 and Figure 8 As shown, the first dummy electrode 21 includes a first sub-portion 21A, and the first sub-portion 21A and the first main electrode 111 are located in different film layers. Along the first direction Z, the first sub-portion 21A covers the first break D1, and the first sub-portion 21A overlaps with 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 with the first sub-portion 21A.

[0088] For example, Figure 8 As shown, the first sub-portion 21A, the first main electrode 111, and the second touch electrode 12 are all in a grid shape, and the overlap of the first sub-portion 21A and the first main electrode 111 means that a line in the first sub-portion 21A overlaps with a line in the first main electrode 111. The overlap of the first sub-portion 21A and the second touch electrode 12 means that a line in the first sub-portion 21A overlaps with a line in the second touch electrode 12.

[0089] It should be noted that Figure 8It only schematically illustrates the situation that the first sub-portion 21A overlaps with the first main electrode 111 and the second touch electrode 12. Figure 8 The tangent line A2A2' in Figure 2 An enlarged representation of the A2A2' tangent line.

[0090] In the present technical solution, the first dummy electrode 21 is a single-layer structure, and the first sub-portion 21A in the first dummy electrode 21 is arranged to cover the first break D1, so that the first dummy electrode 21 covers the first break D1. Moreover, the first dummy electrode 21 is a single-layer structure, which is conducive to reducing the structural complexity of the first dummy electrode 21, thereby helping to reduce the difficulty of preparing the first dummy electrode 21.

[0091] 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 adding an additional process for preparing the first sub-portion 21A and without increasing the thickness of the display panel 01.

[0092] Optional, such as Figure 7 As shown, the display panel 01 further includes a plurality of sub-pixels PX, and the first sub-portion 21A includes a plurality of second A wirings SL2 and a plurality of second B wirings XL2 connected to each other, and the extension directions of the second A wirings SL2 and the second B wirings XL2 intersect with each other.

[0093] The plurality of second wires SL2 and the plurality of second wires XL2 cross to define at least one second dummy grid WG2 , and the projection of the second dummy grid WG2 in the first direction Z encloses at least one sub-pixel PX.

[0094] Based on this arrangement, in the first direction, the first sub-portion 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 prevent the first dummy electrode 21 from blocking light from the sub-pixel PX.

[0095] In one embodiment of the present application, Figure 5A , Fig. 6A , Figure 7 As shown, the orthographic projection of the first dummy electrode 21 on the plane where the first main electrode 111 is located is in a grid shape, and both the first main electrode 111 and the second touch electrode 12 are in a grid shape.

[0096] by Figure 7 For example, the grid-shaped projection of the first dummy electrode 21 on the plane where the first main electrode 111 is located and the grid-shaped first main electrode 111 and the second touch electrode 12 can form a grid structure. That is, the grid-shaped projection of the first dummy electrode 21 on the plane where the first main electrode 111 is located and the grid-shaped first main electrode 111 and the second touch electrode 12 are still in a grid shape.

[0097] At the position where the first main electrode 111 is close to the orthographic projection of the first dummy electrode 21 on 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 routing in the first main electrode 111 and the routing of the first dummy electrode 21 in the orthographic projection of the plane where the first main electrode 111 is located.

[0098] At the position where the second touch electrode 12 is close to the orthographic projection of the first dummy electrode 21 on 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 routing in the second touch electrode 12 and the routing of the first dummy electrode 21 in the orthographic projection of the plane where the first main electrode 111 is located.

[0099] Fig.9A This is an enlarged schematic diagram of a first dummy electrode and a first main electrode adjacent to each other provided in an embodiment of the present application. Fig. 9B An enlarged schematic diagram of a first dummy electrode and a second touch electrode adjacent to each other provided in an embodiment of the present application.

[0100] Combination Fig.9A and Fig. 9B As shown, the orthographic projection of the first dummy electrode 21 on the plane where the first main electrode 111 is located includes a plurality of first lines DL1 forming a grid structure, and the plurality of first lines DL1 can cross each other to form a grid. The first main electrode 111 includes a plurality of second lines DL2 forming a grid structure, and the plurality of second lines DL2 can cross each other to form a grid. The second touch electrode 12 includes a plurality of third lines DL3 forming a grid structure, and the plurality of third lines DL3 can cross each other to form a grid.

Here, a grid with a side length W1 may refer to a grid defined by the intersection of the first line DL1 and the second line DL2.

[0102] and / or, if Fig. 9B As shown, in the first direction, the first line DL1 overlaps with the third line DL3, and the length L2 of the overlap between a first line DL1 and a third line DL3 is not greater than the side length W2 of a grid in the grid structure, that is, L2≤W2. Here, a grid with a side length W2 may refer to a grid defined by the intersection of the first line DL1 and the third line DL3.

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

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

[0105] In the embodiment of the present application, the overlapping length L1 of a first line DL1 and a second line DL2 is set within a certain range, and / or the overlapping length L2 of a first line DL1 and a third line DL3 is set within a certain range. While ensuring that the first dummy electrode 21 effectively covers the first break D1, it is beneficial to avoid 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 helping to avoid 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 the touch accuracy.

[0107] In one embodiment of the present application, Figure 2 , Fig.10 and Fig.11 As shown, at least one of two adjacent first touch electrodes 11 and two adjacent second touch electrodes 12 includes a second break D2, that is, the second break D2 may be included between two adjacent first touch electrodes 11 and / or the second break D2 may be included between two adjacent second touch electrodes 11. Figure 2 The example in which the second break D2 is included between two adjacent first touch electrodes 11 is used for illustration.

[0108] Among them, Fig.11 As shown, 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 including the second break D2, so as to ensure the reliability of the first dummy electrode 21 covering the second break D2. Of course, in the case where 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 including the second break D2.

[0110] For example, Figure 2 As shown, the portion of the first dummy electrode 21 covering the second break D2 is connected to the portion covering the first break D1 .

[0111] Exemplarily, the structure of the portion of the first dummy electrode 21 covering the second break D2 may be the same as the structure of the portion covering the first break D1. For example, the portion of the first dummy electrode 21 covering the second break D2 and the portion covering the first break D1 are both single-layer structures including the first sub-portion 21A. Alternatively, the portion of the first dummy electrode 21 covering the second break D2 and the portion covering the first break D1 are both double-layer structures including the first sub-portion 21A and the first dummy portion 21B.

[0112] Of course, the structure of the portion of the first dummy electrode 21 covering the second break D2 may be different from that of the portion covering the first break D1. For example, the portion of the first dummy electrode 21 covering the first break D1 is a double-layer structure, and the portion of the first dummy electrode 21 covering the second break D2 is a single-layer structure.

[0113] In the embodiment of the present application, the first dummy electrode 21 can also cover the second break D2 in the first direction Z. When the display panel 01 displays an image, the first dummy electrode 21 can also block the light leakage in the second break D2, which is beneficial to avoid the visibility problem of the second break D2 in the displayed image, thereby helping to further improve the display quality of the display panel 01.

Fig. 13B for Fig. 12B A schematic cross-sectional view along the A4A4' tangent line.

[0115] In one embodiment of the present application, the first touch electrodes 11 and the second touch electrodes 12 are both in a grid shape. Figure 2 , Fig. 12A and Fig.13A or combined Figure 2 , Fig. 12B , Fig. 13B As shown, the first touch electrode 11 and / or the second touch electrode 12 include a third break D3, and the third break D3 may be located in the first main electrode 111 of the first touch electrode 11 and / or in the second main electrode 121 of the second touch electrode 12. The length of the third break D3 is greater than the side length of a grid.

[0116] It should be noted that Figure 2 It only illustrates the situation that both the first touch electrode 11 and the second touch electrode 12 include the third break D3 .

[0117] Since the first touch electrodes 11 and the second touch electrodes 12 are both in a grid shape, Fig. 12A and Fig.13A As shown, when the third break D3 is located in the first touch electrode 11, the third break D3 may be a break between one line and another line in the first touch electrode 11, and the length of the break is greater than the side length of a grid in the first touch electrode 11. The first touch electrode 11 may include multiple third breaks D3. Fig. 12B and Fig. 13B As shown, when the third break D3 is located in the second touch electrode 12, the third break D3 may be a break between one routing line and another routing line in the second touch electrode 12, the length of which is greater than the side length of a grid in the second touch electrode 12, and the second touch electrode 12 may include multiple third breaks D3.

[0118] The dummy electrode 200 also includes a second dummy electrode 22, such as Fig.13A and Fig. 13B As shown, along the first direction Z, the second dummy electrode 22 covers the third break D3.

[0119] When both the first touch electrode 11 and the second touch electrode 12 include the third break D3 , the second dummy electrode 22 covering the third break D3 in the first touch electrode 11 and the second dummy electrode 22 covering the third break D3 in the second touch electrode 12 may be separated.

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

[0121] In the embodiment 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 beneficial to reduce the parasitic capacitance between the touch unit 100 and the display electrode, thereby reducing the load of the display electrode when it is working. At the same time, the second dummy electrode 22 is provided to cover the third break D3, so when the display panel 01 displays an image, the second dummy electrode 22 can block the light leakage in the third break D3, which is beneficial to avoid the visibility problem of the third break D3 in the display image, thereby further improving the display quality of the display panel 01.

[0122] In a technical solution of an embodiment of the present application, Fig.13A and Fig. 13B As shown, the second dummy electrode 22 includes a second sub-portion 22A and a second dummy portion 22B. The second dummy portion 22B is in the same layer as the first main electrode 111 and is located in the third break D3.

[0123] like Fig.13A As shown, the second dummy portion 22B includes a third sub-break D31 between the second dummy portion 22B and the adjacent first touch electrode 11, and / or, as shown in FIG. Fig. 13B As shown, a third sub-break D31 is included between the second dummy portion 22B and the adjacent second touch electrode 12 .

[0124] Exemplary, combined Fig. 12A , Fig.13A As shown, the second dummy portion 22B may be in a grid shape, the third sub-break D31 may be a break between a line in the second dummy portion 22B and a line in the first touch electrode 11, and a plurality of third sub-breaks D31 may be included between the second dummy portion 22B and the adjacent first touch electrode 11. Fig. 12B , Fig. 13B As shown, the third sub-break D31 is a break between a wiring in the second dummy portion 22B and a wiring in the second touch electrode 12 , and a plurality of third sub-breaks D31 may be included between the second dummy portion 22B and the adjacent second touch electrode 12 .

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

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

[0127] In the present technical solution, the second dummy portion 22B is arranged 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 portion 22B can fill part of the third break D3. At the same time, the second sub-portion 22A is arranged to cover the third sub-break D31 between the second dummy portion 22B and the first touch electrode 11 and / or the second touch electrode 12, so that the second dummy electrode 22B can cover the third break D3.

[0128] Moreover, the size of the third sub-break D31 is smaller than that of the third break D3, which is beneficial to reducing the process difficulty of the second sub-portion 22A covering the third sub-break D31.

[0129] Optionally, the second sub-portion 22A is in the same layer as the first connection portion 112. In this way, the second sub-portion 22A can be prepared with the same process and material as the first connection portion 112, without adding an additional process for preparing the second sub-portion 22A, and without increasing the thickness of the display panel 01.

[0130] In one implementation of this technical solution, Fig.13A and Fig. 13B As shown, a first insulating layer JC is included between the second sub-portion 22A and the second dummy portion 22B, the first insulating layer JC includes a second through hole K2, and the second sub-portion 22A and the second dummy portion 22B are connected through the second through hole K2.

[0132] The plurality of third A wiring lines SL3 and the plurality of third B wiring lines XL3 intersect to define at least one third dummy grid WG3, and the projection of the third dummy grid WG3 in the first direction encloses at least one sub-pixel PX. The second through hole 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 output of the sub-pixel PX. Moreover, the intersection of the third dummy grid WG3 is usually far away from the sub-pixel PX it surrounds, and the second through hole K2 is arranged at the intersection of the third dummy grid WG3, which helps to reduce the influence of the preparation of the second through hole K2 on the sub-pixel PX, thereby helping to reduce the influence of the preparation of the second through hole K2 on the display effect.

[0134] Optional, such as Fig. 12A , Fig. 12B As shown, in the first direction, the second sub-portion 22A overlaps with 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 with at least part of the second dummy portion 22B. In this way, on the one hand, the second sub-portion 22A does not overlap with the sub-pixel PX in the first direction Z, which is conducive to preventing the second sub-portion 22A from blocking the light output 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 preparing the second dummy electrode 22.

[0140] Based on this arrangement, the second sub-portion 22A and the second dummy portion 22B need to be connected by punching, which is beneficial to simplifying the preparation process of the second dummy electrode 22 and saving costs.

In this way, the second sub-portion 22A can be prepared with the same process and material as the first connection portion 112, without adding an additional process for preparing the second sub-portion 22A, and without increasing the thickness of the display panel 01.

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

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

[0184] For example, Fig.23 As shown, the fixed potential signal line 400 may not surround the display area AA in a closed manner, so as to avoid interference between the fixed potential signal line 400 and other wirings in the frame area NA.

[0185] For example, Fig.24 As shown, Fig.24 This is a schematic plan view of another display panel provided by an embodiment of the present application. The fixed potential signal line 400 is located near the edge of the display area AA, and the fixed potential signal line 400 surrounds the fourth sub-portion 24 .

[0186] Fig.25 A schematic plan view of another display panel provided in an embodiment of the present application.

[0187] In one embodiment of the present application, Fig.25 As shown, the border area NA includes a first border area NA1 and a second border area NA2 located on opposite sides of the display area AA. The first border area NA1 includes a binding area BQ, which is used to bind a control chip (not shown in the figure). The first border area NA1 and the second border area NA2 are arranged along the second direction Y.

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

[0189] Exemplarily, 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 a first touch signal line TX and a second touch signal line RX. The first touch signal line TX is electrically connected to the first touch electrode 11 (connection structure not shown), and the second touch signal line RX is electrically connected to the second touch electrode 12 (connection structure not shown).

[0191] The first touch signal line TX is located in the first frame area NA1, and is electrically connected to the first touch electrode 11 through the first frame area NA1. 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 to 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 to the second touch electrode 12 through the fourth frame NA4.

[0192] Optional, such as Fig.25 As shown, the first border area NA1 includes a first wiring area B1 and a second wiring area B2 where the first touch signal lines TX are arranged, and the first wiring area B1 and the second wiring area B2 are arranged along the third direction X. Among the first touch signal lines TX located in the first border area NA1, a part of the first touch signal lines TX passes through the first wiring area B1, and another part of the first touch signal lines TX passes through the second wiring area B2.

[0193] Combination Fig.26 As shown, Fig.26 for Fig.25 A partial enlarged schematic diagram of the first border area in FIG. 1 shows a gap M 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 line 41 between the fixed potential signal line 400 and the metal pad layer 300 passes through the gap M.

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

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

[0196] Optional, combined Fig.25 and Fig. 27 As shown, Fig. 27 for Fig.25 A partial enlarged schematic diagram of the second frame area in FIG. 4 shows that the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the second frame area NA2. In the second frame area NA2, the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the bridge structure 42.

[0197] The inventor of the present application has found through research that in the second frame area NA2, a protection line GU extending along the third direction X is usually provided between the fixed potential signal line 400 and the metal pad layer 300, and the protection line GU is usually not completely disconnected in the second frame area NA2. Therefore, a bridge structure 42 is provided 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 frame area NA2 , if other wiring extending along the third direction X is provided between the fixed potential signal line 400 and the metal pad layer 300 , the bridge structure 42 can also cross over.

[0199] Optional, such as Fig.25 As shown, the third frame area NA3 includes a third wiring area B3 where the second touch signal line RX is set, and a first area C1 located at one side of the third wiring area B3. The third wiring area B3 and the first area C1 are arranged along the second direction Y.

[0200] Combination Fig.28 As shown, Fig.28 for Fig.25 A partial enlarged schematic diagram of the first area in FIG. 4 shows that the fixed potential signal line 400 is electrically connected to the metal pad layer 300 through the first area C1.

[0201] For example, Fig.28 As shown, the first region C1 includes a protection line GU extending along the second direction Y. In the first region C1 , the fixed potential signal line 400 crosses the shielding line GU via a bridge structure 42 to achieve electrical connection between the fixed potential signal line 400 and the metal pad layer 300 .

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

[0203] Optional, such as Fig.25 As shown, the fourth frame area NA4 includes a fourth wiring area B4 where the second touch signal line RX is set, and a second area C2 located at one side of the fourth wiring area B4. The fourth wiring area B4 and the second area C2 are arranged along the second direction Y.

[0205] For example, Fig.29 As shown, the second region C2 includes a protection line GU extending along the second direction Y. In the second region C2 , the fixed potential signal line 400 crosses the shielding line GU via a bridge structure 42 to achieve electrical connection between the fixed potential signal line 400 and the metal pad layer 300 .

[0206] Of course, in the second area C2 , if other wirings extending along the second direction Y are disposed between the fixed potential signal line 400 and the metal pad layer 300 , the bridge structure 42 can also cross over.

[0208] In one embodiment of the present application, Fig. 30A and Fig. 30B As shown, the first main electrode 111 and the second touch electrode 12 are both in a grid shape, and the display panel 01 also includes a plurality of sub-pixels PX. The first main electrode 111 and the second touch electrode 12 both include a sixth A routing line SL6 and a sixth B routing line XL6 whose extension directions intersect and are electrically connected. The sixth A routing line SL6 and the sixth B routing line XL6 cross to define at least one first grid WK1, and the first grid WK1 surrounds at least one sub-pixel PX.

[0209] For example, Fig. 30A and Fig. 30B As shown, a first grid WK1 surrounds a sub-pixel PX.

[0210] The plurality of sub-pixels PX include a first color sub-pixel PX1 and a second color sub-pixel PX2, and 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 may be the first sub-grid WK11, and the first grid WK1 surrounding the second color sub-pixel PX2 may 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. Fig. 30A and Fig. 30B As shown, the sub-pixel PX further includes a third color sub-pixel PX3 . The third color sub-pixel PX3 is disposed 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 part of the first sub-grid WK11 includes a first slit KF1, and the first slit KF1 may be located on an edge of the first sub-grid WK11, and the length of the first slit KF1 is less than the side length of the first sub-grid WK11. Here, the length of the first slit KF1 refers to the length of the first slit KF1 in the extending direction of the side of the first sub-grid WK11 where the first slit KF1 is located.

[0213] In different first sub-grids WK11, the first slits KF1 have the same orientation. Here, the first slits KF1 have the same orientation, which means that the directions of the first slits KF1 pointing to the first color sub-pixels PX1 surrounded by the first sub-grids WK11 in which they are located are parallel to each other.

[0214] At least part of the second sub-grid WK12 includes a second slit KF2, and the second slit KF2 may be located on the edge of the second sub-grid WK12, and the length of the second slit KF2 is less than the side length of the second sub-grid WK12. Here, the length of the second slit KF2 refers to the length of the second slit KF2 in the extending direction of the side of the second sub-grid WK12 where the second slit KF2 is located.

[0215] In different second sub-grids WK12, the second slits KF2 have the same orientation. Here, the second slits KF2 have the same orientation, which means that the directions of the second slits KF2 pointing to the second color sub-pixels PX2 surrounded by the second sub-grids WK12 in which they are located are parallel to each other.

[0216] In the embodiment of the present application, the first slits KF1 are all oriented in the same direction, and the second slits KF2 are all oriented in the same direction, which is beneficial to improving the problem of observing diagonal lines at a wide viewing angle, thereby improving the display quality of the display panel 01.

[0217] Optional, such as Fig. 30A and Fig. 30B The direction of the first slit KF1 crosses the direction of the second slit KF2, that is, the direction of the first slit KF1 pointing to the first color sub-pixel PX1 surrounded by the first sub-grid WK11 where it is located crosses the direction of the second slit KF2 pointing to the second color sub-pixel PX2 surrounded by the second sub-grid WK12 where it is located.

[0218] Furthermore, the orientation of the first slit KF1 is perpendicular to the orientation of the second slit KF2.

[0219] Based on this setting method, it is helpful to further improve the problem of observing diagonal lines at a wide viewing angle.

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

[0221] In one embodiment of the present application, Fig. 30A and Fig. 30B As shown, the first main electrode 111 and the second touch electrode 12 are both in a grid shape. At least one of the first main electrode 111 and the second touch electrode 12 includes a slit KF, and the length of the slit KF is less than the side length of a grid. Fig. 30A The first main electrode 111 includes a slit KF. Fig. 30BThe diagram shows a case where the second touch electrode 12 includes a slit KF.

[0222] Combination Fig.31 As shown, Fig.31 A schematic diagram of the local structure of a display panel provided in an embodiment of the present application, the display panel 01 further includes a light extraction structure MLP, which is located on the side of the slit KF facing the light emitting surface of the display panel 01, and 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 exiting.

[0224] For example, Fig.31 As shown, the first layer MLP1 includes an opening P, and the opening P overlaps with the slit KF in the first direction Z. The second layer MLP2 covers the first layer MLP1, and the refractive index of the second layer MLP2 is greater than the refractive index of the first layer MLP1.

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

[0226] In the embodiment of the present application, since the refractive index of the first layer MLP1 is smaller than the refractive index of the second layer MLP2, the large-angle light emitted from the slit KF can be converted into light of a smaller angle and emitted after passing through the light extraction structure MLP, which can reduce the large-angle light emitted from the slit KF, and is beneficial to alleviating the problem of observing diagonal lines at a wide viewing angle due to the large-angle light emission of the slit KF, thereby helping to improve the display quality of the display panel 01.

[0227] In one embodiment of the present application, Fig. 30A and Fig. 30B As shown, the first main electrode 111 and the second touch electrode 12 are both in a grid shape. At least one of the first main electrode 111 and the second touch electrode 12 includes a slit KF, and the length of the slit KF is less than the side length of a grid. Fig. 30A The first main electrode 111 includes a slit KF. Fig. 30B The diagram shows a case where the second touch electrode 12 includes a slit KF.

[0228] like Fig.32 As shown, Fig.32 This is a schematic diagram of a partial structure of another display panel provided in an embodiment of the present application. The display panel 01 further includes a microlens structure OC. In the first direction Z, the microlens structure OC covers the slit KF.

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

[0230] In the embodiment of the present application, the large-angle light emitted from the slit KF can be converted into light with a smaller angle and emitted after passing through the microlens structure OC, which can reduce the large-angle light emitted from the slit KF, and is beneficial to alleviating the problem of observing diagonal lines at a wide viewing angle due to the large-angle light emission of the slit KF, thereby helping to improve the display quality of the display panel 01.

[0231] In one embodiment of the present application, Figure 5A , Fig. 6A and Figure 7 As shown, the first touch electrode 11, the second touch electrode 12 and the first dummy electrode 21 are all in a grid shape, and no slits are set in the grids of the first touch electrode 11, the second touch electrode 12 and the first dummy electrode 21. Here, a slit refers to a break whose length is less than the length of a grid side, such as Fig. 30A and Fig. 30B The notch KF in the.

[0232] In the embodiment of the present application, no slits are provided in the grids of the first touch electrodes 11 , the second touch electrodes 12 and the first dummy electrodes 21 , which is beneficial to avoid the large viewing angle stripe problem caused by the slits, thereby further improving the display quality of the display panel 01 .

[0233] The present application embodiment provides a display panel 01, such as Figure 1 As shown, the display panel 01 includes a plurality of touch control units 100 . The touch control unit 100 includes a first touch control electrode 11 and a second touch control electrode 12 . The first touch control electrode 11 is electrically insulated from the second touch control electrode 12 .

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

[0235] Combination Figure 2 As shown, the first touch electrode 11 includes a first main electrode 111 and a first connecting portion 112 . In the same first touch electrode 11 , two adjacent first main electrodes 111 are electrically connected via the first connecting portion 112 .

[0237] 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 via the second connecting portion 122 .

[0238] For example, Figure 2 As shown, one second touch electrode 12 may include two second main electrodes 121 and a second connecting portion 122 connecting the two second main electrodes 121 .

[0239] Combination Fig.21 and Fig. 22 As shown, in the first direction Z, the first connection portion 112 overlaps with the second touch electrode 12 .

[0240] Exemplarily, the second main electrode 121 and the second connecting portion 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 portion 112 and the second touch electrode 12 are in different film layers. That is, the first main electrode 111 and the first connecting portion 112 are in different film layers.

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

[0242] Exemplary, combined Figure 5A and Fig.21 , Fig. 22 As shown, the first main electrode 111 and the second touch electrode 12 are both in a grid shape, and along the first direction Z, the grid projection of the fourth sub-portion 24 at least partially overlaps with the grid projections of the first main electrode 111 and the second touch electrode 12. The first direction Z is perpendicular to the plane where the display panel 01 is located. It should be noted that Fig.21 Only the situation where the fourth sub-portion 24 overlaps with the first main electrode 111 is illustrated.

[0243] The fourth sub-unit 24 receives a fixed potential signal.

[0244] In the embodiment of the present application, the fourth sub-portion 24 is located between the first main electrode 111 and the display cathode COM of the display panel 01, and the fourth sub-portion 24 receives a fixed potential signal, so 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. Moreover, the grid-shaped fourth sub-portion 24 can have no overlap with the sub-pixels in the display panel 01, so as to avoid the fourth sub-portion 24 affecting the normal display of the display panel 01.

[0245] Exemplarily, the display panel 01 provided in the present application may further include a polarizer, and the polarizer is disposed on a side of the touch unit 100 facing the light emitting surface of the display panel.

[0246] Exemplarily, the display panel 01 provided in the present application may further include a color resist layer, and the color resist layer is disposed on a side of the touch control unit 100 facing the light emitting surface of the display panel 01 .

Exemplarily, the display device 02 can be an electronic device such as a mobile phone, a computer, a television, a car display, a wearable display, etc. This application does not make specific limitations.

[0249] In the display device 02, a first dummy electrode 21 is provided to cover the first break D1 in the first direction Z. When the display panel 01 displays an image, the first dummy electrode 21 can block light leakage in the first break D1, which is beneficial to avoid the visibility problem of the first break D1 in the display image, thereby helping to improve the display quality of the display panel 01.

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