[0059] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0061] The display panel of the related art has the problem of poor display effect. The inventor has found through research that the reason for the above problem is that in the display panel of the related art, for the wiring arranged on different layers, vias are used to connect the wiring at the position where the wiring needs to be connected, and no vias are set at the position where the wiring does not need to be connected, so that when the light enters the display panel, there is a difference in the degree of reflection at the via and non-via positions, which makes the brightness uneven when the screen is turned off or when the picture is displayed, affecting the display effect.

[0062] Based on the above reasons, an embodiment of the present invention provides a display panel. Figure 1 is a schematic diagram of a top view structure of a display panel provided by an embodiment of the present invention, Figure 2 is a cross-sectional view of a display panel provided by an embodiment of the present invention, Figure 3 is a cross-sectional view of another display panel provided by an embodiment of the present invention, Figure 2 Can correspond Figure 1 Cut along BB' to get, Figure 3 Can correspond Figure 1 Cut along CC', reference Figure 1-Figure 3 Optionally, the display panel 01 includes: a display area AA, the display panel includes: a substrate 10, a plurality of first wirings 20, a plurality of second wirings 30 and a plurality of first conductive parts 60.

[0063] A plurality of first routing lines 20 and a plurality of second routing lines 30 are located on the substrate 10 and in the display area AA. The first routing lines 20 and the second routing lines 30 are arranged in different layers. Each first routing line 20 of at least some of the first routing lines 20 is provided with a corresponding first-type second routing line 30 and a second-type second routing line 30. The overlapping position of the first routing line 20 and the corresponding first-type second routing line 30 may be a first overlapping position. The first routing line 20 and the corresponding first-type second routing line 30 are connected at the first overlapping position through a first via 40. The orthographic projection of the first routing line 20 on the substrate 10 overlaps with the orthographic projection of the corresponding second-type second routing line 30 on the substrate 10. The overlapping position of the first routing line 20 and the corresponding second-type second routing line 30 may be a second overlapping position, and an insulating layer 50 is provided between the first routing line 20 and the corresponding second-type second routing line 30 at the second overlapping position, that is, no via connecting the first routing line 20 and the corresponding second-type second routing line 30 is provided at the second overlapping position.

[0064] The overlapping position of the second-type second routing 30 corresponding to the first routing 20 and the corresponding first conductive portion 60 may be a third overlapping position. The second-type second routing 30 corresponding to the first routing 20 and the corresponding first conductive portion 60 are connected at the third overlapping position through a second via 70, and the orthographic projection of the second via 70 on the substrate 10 is located outside the orthographic projection of the first routing 20 on the substrate 10.

[0065] Specifically, the substrate 10 can be used to provide protection and support for the display panel, wherein the substrate 10 can be a flexible substrate formed of materials such as polyimide (PI), polyethylene naphthalate (PEN) or polyethylene terephthalate (PET), or a hard substrate formed of materials such as glass. A plurality of conductive layers are arranged on one side of the substrate 10, and an insulating layer 50 is arranged between adjacent conductive layers, for example, which can be isolated from each other. The first wiring 20 and the second wiring 30 can be located in different conductive layers. The first wiring 20 can be a signal line for transmitting electrical signals, and the first wiring 20 can also be disconnected from electrical signals. Similarly, the second wiring 30 can be a signal line for transmitting electrical signals, and the second wiring 30 can also be disconnected from electrical signals.

[0066] In this embodiment, the second routing line 30 includes a first type of second routing line 30 and a second type of second routing line 30 corresponding to the first routing line 20, wherein the first type of second routing line 30 corresponding to the first routing line 20 is a second routing line 30 connected to the first routing line 20, and the second type of second routing line 30 corresponding to the first routing line 20 may be a second routing line 30 not connected to the first routing line 20, or the second type of second routing line 30 corresponding to the first routing line 20 may be a second routing line 30 electrically connected to the first routing line 20. The first type of second routing lines 30 corresponding to different first routing lines 20 may be different, and the second type of second routing lines 30 corresponding to different first routing lines 20 may also be different, or the second type of second routing lines 30 corresponding to different first routing lines 20 may be partially the same, or partially different, or the second type of second routing lines 30 corresponding to different first routing lines 20 may be the same. Exemplarily, for Figure 1 In the display panel shown, the first type of second routing 30 corresponding to the first first routing 20 along the second direction y (for example, the first routing 20 on the upper side) is the first second routing 30 along the first direction x (the second routing 30 on the leftmost side), and the others are corresponding second type of second routing 30; the first type of second routing 30 corresponding to the second first routing 20 along the second direction y (for example, the second first routing 20 starting from the upper side of the display panel) is the second second routing 30 along the first direction x (the second second routing 30 starting from the leftmost side), and the others are corresponding second type of second routing 30.

[0067] The orthographic projections of the first routing line 20 and the corresponding first-type second routing line 30 on the substrate 10 overlap, and the first routing line 20 and the corresponding first-type second routing line 30 are connected by a first via 40 at the overlapping position of the first routing line 20 and the corresponding first-type second routing line 30 (i.e., the first overlapping position), so that the first routing line 20 and the corresponding first-type second routing line 30 transmit the same signal. The orthographic projections of the first routing line 20 and the corresponding second-type second routing line 30 on the substrate 10 overlap, and an insulating layer 50 is provided between the first routing line 20 and the corresponding second-type second routing line 30 at the overlapping position of the first routing line 20 and the corresponding second-type second routing line 30 (i.e., the second overlapping position), that is, there is no connection between the first routing line 20 and the corresponding second-type second routing line 30 at the second overlapping position, and the first routing line 20 and the corresponding second-type second routing line 30 can transmit different signals, or the first routing line 20 and the corresponding second-type second routing line 30 are connected by vias at positions other than the second overlapping position, and the first routing line 20 and the corresponding second-type second routing line 30 can transmit the same signal.

[0068] In this embodiment, the display panel further includes a plurality of first conductive portions 60, and the orthographic projections of part or all of the first conductive portions 60 on the substrate 10 are located outside the orthographic projections of the first wiring 20 on the substrate 10. Optionally, the first conductive portions 60 are insulated from the first wiring 20. In some embodiments, in the thickness direction of the display panel, the first conductive portions 60 and the first wiring 20 are arranged on the same side of the second wiring 30. The orthographic projections of the first conductive portions 60 and the second type of second wiring 30 corresponding to the first wiring 20 on the substrate 10 overlap, and at the overlapping position (i.e., the third overlapping position), the first conductive portions 60 and the second type of second wiring 30 corresponding to the first wiring 20 are connected through the second via 70. That is, different from the related art, in the embodiment of the present invention, not only is a first via 40 set at the first overlapping position of the first routing 20 and the corresponding first-type second routing 30, but a second via 70 is also set at the third overlapping position of the second-type second routing 30 corresponding to the first routing 20 and the first conductive portion 60. In this way, the via setting of the second-type second routing 30 corresponding to the first routing 20 can be made closer to the via setting of the first-type second routing 30 corresponding to the first routing 20, so that at the positions of the first via 40 corresponding to the first-type second routing 30 corresponding to the first routing 20 and the second via 70 corresponding to the second-type second routing 30 corresponding to the first routing 20, the degree of light blocking or reflection is relatively close or the same, thereby improving the problem of uneven brightness and enhancing the display effect of the display panel.

[0069] In some optional embodiments of the present invention, along the first direction x, the size of the second via 70 is equal to the size of the first via 40; and / or, along the second direction y, the size of the second via 70 is equal to the size of the first via 40. At least part of the first trace 20 extends along the first direction x, and at least part of the second trace 30 extends along the second direction y. In this way, the shading and reflecting effects of the second via 70 are more consistent with those of the first via 40, which is conducive to further improving display uniformity. At least part may include part or all.

[0070] Optionally, the first via 40 includes a first side wall 41, and the second via 70 includes a second side wall 71, and the inclination angle of the first side wall 41 is equal to the inclination angle of the second side wall 71. The equal inclination angles of the first side wall 41 and the second side wall 71 refer to that the inclination angles of the first side wall 41 and the corresponding second side wall 71 are equal, for example, along the first direction x, the inclination angles of the first side wall 41 and the second side wall 71 on the same side of the first via 40 and the second via 70 are equal; along the second direction y, the inclination angles of the first side wall 41 and the second side wall 71 on the same side of the first via 40 and the second via 70 are equal, wherein, Figure 2 and Figure 3 Schematically shows that along the second direction y, the left side wall inclination angle a1 of the first via 40 is equal to the left side wall inclination angle b1 of the second via 70, and the right side wall inclination angle a2 of the first via 40 is equal to the right side wall inclination angle b2 of the second via 70. In some embodiments, the left side wall inclination angle a1 of the first via 40 is equal to the right side wall inclination angle a2 of the first via 40. In this way, the second side wall 71 of the second via 70 and the first side wall 41 of the first via 40 reflect light more consistently, which is more conducive to improving display uniformity. For example, the first via 40 and the second via 70 have the same shape and / or the same size. For example, the first cross section of the first via 40 and the second via 70 have the same shape and / or the same size. For example, the second cross section of the first via 40 and the second via 70 have the same shape and the same size. The first cross section may be perpendicular to the substrate and may be parallel to the first direction x. The second cross section may be perpendicular to the substrate and may be parallel to the second direction y. For example, the orthographic projections of the first via hole 40 and the second via hole 70 on the substrate close to the substrate have the same shape and size. For example, the orthographic projections of the first via hole 40 and the second via hole 70 on the substrate far from the substrate have the same shape and size.

[0071] Figure 4 The structural diagram of the display panel in the related art, refer to Figure 4In the related art, the lower frame of the display panel includes a fan-out area SA, and each data line Data in the display panel is connected to the driver chip 02 through a fan-out line SL located in the fan-out area SA. Since the width of the driver chip 02 is usually smaller than the width of the display area AA of the display panel, the data lines Data located at the edges of the display area need to be connected to the driver chip 02 through a bent or folded fan-out line SL, or a fan-out line SL that extends in a different direction from the data line Data, resulting in a large area occupied by the fan-out line SL in the fan-out area SA, making it difficult for the display panel to achieve a narrow frame.

[0072] Figure 5 is a schematic diagram of a top view of another display panel provided by an embodiment of the present invention, Figure 6 is a cross-sectional view of another display panel provided by an embodiment of the present invention, Figure 7 is a cross-sectional view of another display panel provided by an embodiment of the present invention, wherein: Figure 6 Can correspond Figure 5 Cut along DD' to get, Figure 7 Can correspond Figure 5 Cut along EE' to obtain reference Figure 5-Figure 7 ,and Figure 4The structure of the display panel in the related art is different. In the present embodiment, the display panel also includes: a plurality of data lines Data, located on the substrate 10; at least a portion of the first wiring 20 extends along the first direction x, and at least a portion of the second wiring 30 extends along the second direction y, and the first direction x intersects with the second direction y, for example, vertically; the first wiring 20 includes a first adapter line 211, and the first type of second wiring 30 includes a second adapter line 311; the first adapter line 211 is correspondingly connected to the data line Data, and the first adapter line 211 crosses at least one second type of second wiring 30 and is connected to the second adapter line 311. Optionally, the display area includes a first display area AA1 and a second display area AA2. Along the first direction x, the second display area AA2 is located at least on one side of the first display area AA1, for example, the second display area AA2 is located on one side or both sides of the two opposite sides of the first display area AA1; at least part of the first adapter line 211 is connected to the data line Data in the second display area AA2, and at least part of the first adapter line 211 crosses at least one second-type second routing line 30 and is connected to the second adapter line 311 of the first display area AA1; the second adapter line 311 of the first display area AA1 is used to connect the binding pin; along the thickness direction z of the display panel, the first conductive part 60 and the first adapter line 211 are located on the same side of the corresponding second-type second routing line 30 and are arranged at intervals; along the second direction y, at least part of the first conductive part 60 is located on one side of the first adapter line 211, and overlaps with the orthographic projection of the second-type second routing line 30 crossed by the first adapter line 211 on the substrate 10, and is connected to the second-type second routing line 30 through the second via 70 at the third overlapping position. At least part may include part or all or one or more. At least one may include one or more.

[0073] In this embodiment, the first adapter wire 211 is electrically connected to the data line Data in the second display area AA2, the first adapter wire 211 is electrically connected to the second adapter wire 311 in the first display area AA1, and the second adapter wire 311 is also connected to the binding pin, so that the binding pin can be electrically connected to the data line Data through the second adapter wire 311 and the first adapter wire 211. The binding pin can be connected to the pin on the driver chip 02 by conductive glue, and accordingly, the driver chip 02 can be electrically connected to the data line Data through the second adapter wire 311 and the first adapter wire 211. Figure 5 As shown, the first display area AA1 is the middle area of ​​the display area, and the second display area AA2 is the edge area of ​​the display area. By setting the first adapter line 211 and the second adapter line 311, the data line Data of the second display area AA2 can be transferred to the binding pin in the display area. Compared with the related art in which the fan-out area is located in the non-display area, this embodiment is equivalent to setting the fan-out area in the display area of ​​the display panel. In this way, the area of ​​the non-display area can be reduced, for example, the area of ​​the non-display area can be reduced. Figure 4The area of ​​the middle and lower borders is used to achieve a narrow border for the display panel.

[0074] The first adapter line 211 is connected to the data line Data in the second display area AA2, and the first adapter line 211 crosses over at least one second-type second routing line 30 to connect to the second adapter line 311 in the first display area AA1, which means that at least one second-type second routing line 30 is arranged between the data line Data connected to the first adapter line 211 and the second adapter line 311 connected to the first adapter line 211, and the orthographic projection of the second-type second routing line 30 on the substrate 10 overlaps with the orthographic projection of each second-type second routing line 30 in the at least one second-type second routing line 30 on the substrate 10. The first adapter line 211 may be located on the side of the second-type second routing line 30 away from the substrate, and the first adapter line 211 may cross over at least one second-type second routing line 30 from above, or the first adapter line 211 may be located on the side of the second-type second routing line 30 close to the substrate, and the first adapter line 211 may cross over at least one second-type second routing line 30 from below.

[0075] The orthographic projections of the first adapter wire 211 and the corresponding second adapter wire 311 on the substrate 10 overlap, and at the overlapping position of the first adapter wire 211 and the corresponding second adapter wire 311 on the substrate 10 (that is, the first overlapping position), the two are connected through the first via 40. In this embodiment, along the second direction y, at least part of the first conductive portion 60 is located on one side of the first adapter wire 211, and overlaps with the orthographic projection of the second type of second routing line 30 crossed by the first adapter wire 211 on the substrate 10, and is connected to the second type of second routing line 30 through the second via 70 at the third overlapping position. In this way, not only the first via 40 is set at the position of the first adapter wire 211 and the corresponding second adapter wire 311, but also the second via 70 is set near the second type of second routing line 30 crossed by the first adapter wire 211, which can reduce the second adapter wire 311 connected to the first adapter wire 211. The difference in the via setting of the first adapter wire 211 and the via setting of the second type of second routing line 30 crossed by the first adapter wire 211 can make the via setting of the second adapter wire 311 corresponding to the first adapter wire 211 closer to the via setting of the second type of second routing line 30 crossed by the first routing line 20, so that the degree of light reflection at the positions of the first via 40 corresponding to the second adapter wire 311 corresponding to the first adapter wire 211 and the second via 70 corresponding to the second type of second routing line 30 crossed by the first adapter wire 211 are relatively close, thereby improving the problem of uneven brightness when the screen is off or on, and enhancing the display effect of the display panel. In the thickness direction z of the display panel, the first conductive part 60 and the first adapter line 211 are located on the same side of the second type second wiring 30, and the first via 40 connecting the first adapter line 211 and the second adapter line 311 included in the first type second wiring 30 and the second via 70 connecting the first conductive part 60 and the second type second wiring 30 are both connected to the second wiring 30 from the same side of the second wiring 30, so that the first via 40 and the second via 70 have a closer light shielding or reflection effect on light. For example, the first via 40 and the second via 70 are arranged in the same film layer, and the first via 40 and the second via 70 have the same height in the substrate thickness direction, and / or the first via 40 and the second via 70 have the same distance from the substrate on the side close to the substrate and the substrate in the substrate thickness direction, and / or the first via 40 and the second via 70 have the same distance from the substrate on the side far from the substrate and the substrate in the substrate thickness direction.

[0076] Figure 8 is a partial top view of another display panel provided by an embodiment of the present invention, Fig. 9 is a partial top view of another display panel provided by an embodiment of the present invention. Fig. 9 Can correspond Figure 8 Some structural layers in Fig.10 is a cross-sectional view of another display panel provided by an embodiment of the present invention, Fig.10Can correspond Figure 8 Cut along MM', reference Figure 8-Figure 10 Optionally, the first adapter line 211 includes a first main body portion 2111 and a first connecting portion 2112, wherein the first main body portion 2111 extends along a first direction x; the first connecting portion 2112 is connected to the first main body portion 2111, and along a second direction y, the first connecting portion 2112 is located on one side of the first main body portion 2111; the first connecting portion 2112 is connected to the second adapter line 311 through a first via 40.

[0077] The first main body 2111 and the first connecting portion 2112 may be located in the same conductive layer, that is, the first connecting portion 2112 is arranged in the same layer as the first main body 2111. The first main body 2111 and the first connecting portion 2112 may be an integral structure. The first main body 2111 extending along the first direction x may include that the first main body 2111 extends as a whole along the first direction x in a straight line, a curve, a fold line, an irregular shape, or a combination of one or more shapes.

[0078] Because the orthographic projection of the first conductive part 60 on the substrate 10 is located outside the orthographic projection of the first wiring 20 on the substrate 10, in this embodiment, a first connecting part 2112 is arranged along the second direction y and is located on one side of the first main body part 2111. The first connecting part 2112 is connected to the second adapter line 311 through the first via 40. By adjusting the position of the first via 40, the distance between the second via 70 connecting the first conductive part 60 and the second wiring 30 and the first via 40 in the second direction y is shortened, which is beneficial to further improve the brightness uniformity and the display effect.

[0079] For example, at least one second type second wiring 30 crossed by the first adapter 211 is insulated from the first adapter 211, that is, not electrically connected, so the orthographic projection of the second via on the substrate 10 is located outside the orthographic projection of the first adapter 211 on the substrate 10, that is, they do not overlap and are staggered. By setting the first connecting portion 2112, the position of the first via 40 is adjusted so that the distance between the second via 70 and the first via 40 in the second direction y is small, and is close to being located on a straight line extending along the first direction x, so as to reduce off-screen Mura (uneven display).

[0080] Optionally, the orthographic projection of the first connection portion 2112 on the substrate 10 overlaps with the orthographic projection of the first type second routing line 30 on the substrate 10, and at the overlapping position of the two (ie, the first overlapping position), the first connection portion 2112 is connected to the first type second routing line 30 through the first via 40.

[0081] In some embodiments, the first connection portions 2112 of different first adapter lines 211 have equal sizes along the second direction y; on the one hand, the resistances of the first connection portions 2112 of different first adapter lines 211 are close, which is beneficial to improving the brightness uniformity of the display panel in terms of electrical performance; on the other hand, the differences in the reflection of light by the first connection portions 2112 of different first adapter lines 211 are reduced, which is beneficial to improving the brightness uniformity and display effect in terms of optical performance.

[0082] In some embodiments, the first connection portions 2112 of different first adapter lines 211 have the same size along the first direction x. In this way, the brightness uniformity can be improved in terms of both electrical performance and optical performance, further improving the display effect.

[0083] Continue to refer Figure 8-Figure 10 Optionally, corresponding to the same first main body 2111, along the second direction y, at least part of the second vias 70 and the first vias 40 are located on the same side of the same first main body 2111. This arrangement can make the second vias 70 and the first vias 40 relatively closer to the first main body 2111 in the second direction y, which is beneficial to further improve the brightness uniformity and display effect. For example, the second vias 70 and the first vias 40 corresponding to the same first main body 2111 refer to the second vias 70 and the first vias 40 that are adjacent to, close to, or closest to the same first main body 2111.

[0084] For example, the second via 70 and the first via 40 corresponding to the same first routing line refer to the second via 70 and the first via 40 that are adjacent to, close to, or closest to the same first routing line.

[0085] Optionally, corresponding to the same first main body 2111, at least part of the second vias 70 and the first vias 40 are located on the same straight line extending along the first direction x. In some embodiments, corresponding to the same first main body 2111, along the second direction y, the distance d2 between the second via 70 and the first main body 2111 is equal to the distance d1 between the first via 40 and the first main body 2111. In this way, the positions of the second vias 70 and the first vias 40 relative to the first main body 2111 along the second direction y can be the same, so that the first vias 40 and the second vias 70 are evenly distributed on the display panel, further improving the brightness uniformity and the display effect.

[0086] For example, corresponding to the same first main body portion 2111 , along the second direction y, the distances d1 between the plurality of first via holes 40 and the first main body portion 2111 are equal or different.

[0087] Optionally, corresponding to the same first main body 2111, along the first direction x, the distances between two adjacent first-type via holes located on the same straight line are equal, and the two adjacent first-type via holes include adjacent first via holes 40 and second via holes 70, or adjacent two second via holes 70, or adjacent two first via holes 40. In this way, the first-type via holes can be evenly distributed along the first direction x, thereby improving the brightness uniformity in the first direction x and improving the display effect.

[0088] Optionally, in the second direction y, the distances d1 between different first adapter wires 211 and the corresponding first vias 40 are equal; and / or, in the second direction y, the distances d2 between different first adapter wires 211 and the corresponding second vias 70 are equal; wherein the second vias 70 corresponding to the first adapter wires 211 include the second vias 70 on one side of the second type of second routing wire (e.g., the second adapter wire 311) crossed by the first adapter wire 211 in the thickness direction z of the display panel. Such an arrangement can make the distribution of the first type of vias more uniform along the second direction y, thereby further improving the brightness uniformity of the display panel and improving the display effect.

[0089] Fig.11 is a structural schematic diagram of another display panel provided by an embodiment of the present invention, Fig.12 is a partial top view of another display panel provided by an embodiment of the present invention, with reference to Fig.11 and Fig.12 Optionally, the display area includes a third display area AA3 and a fourth display area AA4, and the third display area AA3 and the fourth display area AA4 are arranged along the second direction y; the first routing line 20 includes a first sub-routing line 21 located in the third display area AA3, and at least a portion of the structure of the first sub-routing line 21 serves as a first adapter line 211.

In this embodiment, the third display area AA3 and the fourth display area AA4 are arranged along the second direction y, the first display area AA1 and the second display area AA2 are arranged along the first direction x, the third display area AA3 overlaps with the first display area AA1 and the second display area AA2, and the fourth display area AA4 also overlaps with the first display area AA1 and the second display area AA2. Among them, the connection between the first adapter line 211 and the data line Data, and the connection between the first adapter line 211 and the second adapter line 311 are both realized in the third display area AA3.

[0091] Continue to refer Fig.11 and Fig.12Optionally, the first sub-route 21 also includes a first compensation line 212, and a first break D1 is provided between the first compensation line 212 and the first adapter line 211 of the same first sub-route 21. In this way, there is no connection between the first compensation line 212 and the first adapter line 211, and insulation between the first compensation line 212 and the first adapter line 211 is achieved. Accordingly, the first compensation line 212 is not connected to the data signal on the data line Data. By setting the first sub-route 21 to include the first adapter line 211 and the first compensation line 212, the first compensation line 212 and the first adapter line 211 can have the same shading and / or reflecting effect on the light incident on the display panel, thereby improving the display effect of the display panel and improving the uneven brightness phenomenon when the screen is off or on.

[0092] Optionally, the first compensation line 212 crosses over at least one second-type second routing line 30, and at least a portion of the first conductive portion 60 overlaps with the orthographic projection of the second-type second routing line 30 crossed by the first compensation line 212 on the substrate 10, and along the second direction y, at least a portion of the first conductive portion 60 is connected to the second-type second routing line 30 on one side of the first compensation line 212 through a second via 70.

[0093] The first compensation line 212 crossing over at least one second type second routing line 30 means that the orthographic projection of the first compensation line 212 on the substrate 10 overlaps with the orthographic projection of at least one second type second routing line 30 on the substrate 10. For example, the first compensation line 212 may cross over at least one second type second routing line 30 from above or below. By setting at least part of the first conductive portion 60 to be connected to the second routing line 30 through the second via 70 on one side of the first compensation line 212, a second via 70 is also set on one side of the first compensation line 212, and the second via 70 is also connected to the second routing line 30, so that the via setting conditions near the first compensation line 212 of the first sub-routing line 21 and the first adapter line 211 are relatively consistent, so that the light reflection conditions at the second via 70 on one side of the first compensation line 212 and the first via 40 and the second via 70 on one side of the first adapter line 211 are relatively consistent, so that the brightness uniformity can be further improved, and the brightness unevenness phenomenon in the off or on screen state can be improved.

[0094] Optionally, the first routing 20 also includes a second sub-routing 22, the second sub-routing 22 is located in the fourth display area AA4, the second sub-routing 22 crosses at least one second-type second routing 30, at least part of the first conductive portion 60 overlaps with the positive projection of the second-type second routing 30 crossed by the second sub-routing 22 on the substrate 10, and along the second direction y, at least part of the first conductive portion 60 is connected to the second-type second routing 30 on one side of the second sub-routing 22 through a second via 70.

[0095] By setting the first routing line 20 to also include the second sub-routing line 22 located in the fourth display area AA4, the first routing line 20 can be evenly distributed in the third display area AA3 and the fourth display area AA4, so that the first sub-routing line 21 and the first adapter line 211 in the third display area AA3 play a shading or reflecting role, and the second sub-routing line 22 in the fourth display area AA4 plays a shading or reflecting role, thereby improving the brightness uniformity of the third display area AA3 and the fourth display area AA4.

[0096] The second sub-route 22 crossing over at least one second-type second-route 30 means that the orthographic projection of the second sub-route 22 on the substrate 10 overlaps with the orthographic projection of at least one second-type second-route 30 on the substrate 10. For example, the second sub-route 22 may cross over at least one second-type second-route 30 from above or below. The second sub-route 22 is located in the fourth display area AA4, and the second sub-route 22 may not be connected to the data signal. In this embodiment, at least part of the first conductive portion 60 is arranged to overlap with the positive projection of the second type of second routing 30 crossed by the second sub-routing 22 on the substrate 10, and along the second direction y, at least part of the first conductive portion 60 is connected to the second type of second routing 30 through the second via 70 on one side of the second sub-routing 22, so that the second via 70 is also arranged on one side of the second sub-routing 22, and the second via 70 connects the second routing 30 and the first conductive portion 60, so that the via setting near the second sub-routing 22 is more consistent with the via setting near the first sub-routing 21, and the reflection of light near the second sub-routing 22 is more consistent with the reflection of light near the first sub-routing 21. In this way, the brightness uniformity of the third display area AA3 and the fourth display area AA4 can be made closer, thereby improving the uneven brightness phenomenon when the screen is off or on.

[0098] Among them, the first adapter line 211 crossing over at least one second type second wiring 30 means that the orthographic projection of the first adapter line 211 on the substrate 10 overlaps with the orthographic projection of at least one second type second wiring 30 on the substrate 10. For example, the first adapter line 211 can cross over at least one second type second wiring 30 from above or below. By setting at least one first conductive part 60 along the second direction y to be electrically connected to the second adapter line 311 through the second via 70 on one side of the first adapter line 211, the second via 70 is also set near the second adapter line 311 crossed by the first adapter line 211, so that the second via 70 and the first conductive part 60 are more evenly distributed in the display panel, further improving the display uniformity in the off or on screen state, and enhancing the display effect.

In this way, there is no connection between the second compensation line 312 and the second adapter line 311, and insulation between the second compensation line 312 and the second adapter line 311 is achieved. Accordingly, the second compensation line 312 is not connected to the data signal on the data line Data. By setting the third sub-route 31 to include the second adapter line 311 and the second compensation line 312, the second compensation line 312 and the second adapter line 311 can have the same shading and / or reflecting effect on the light incident on the display panel, thereby improving the display effect of the display panel and improving the uneven brightness when the screen is off or on.

[0107] In some embodiments, in the fourth display area AA4, at least one second sub-route 22 crosses over at least one second compensation line 312 (which can serve as a second type of second route of the second sub-route 22); along the second direction y, at least one first conductive portion 60 is electrically connected to the second compensation line 312 through a second via 70 on one side of the second sub-route 22.

For example, the second sub-route 22 may cross over at least one second compensation line 312 from above or below. By setting at least a portion of the first conductive portion 60 to be connected to the second compensation line 312 through the second via 70 on one side of the second sub-route 22, a second via 70 is also set on one side of the second sub-route 22, and the second via 70 is also connected to the second compensation line 312. On the one hand, the via setting conditions near the second sub-route 22 and the first sub-route 21 are relatively consistent, so that the light reflection conditions near the second sub-route 22 and the first sub-route 21 are relatively consistent; on the other hand, the via setting conditions near the second adapter line 311 and the second compensation line 312 of the third sub-route 31 are relatively consistent, so that the light reflection conditions near the second adapter line 311 and the second compensation line 312 of the third sub-route 31 are relatively consistent. In this way, the brightness uniformity can be further improved, and the brightness unevenness in the screen-off or screen-on state can be improved.

In the third display area AA3, at least part of the first adapter line 211 crosses over at least one fourth sub-routing line 32 (which can be used as the second type of second routing line of the first adapter line 211).

For example, at least part of the first compensation line 212 overlaps with the third sub-line 31, and / or, at least part of the first compensation line 212 overlaps with the fourth sub-line 32, and / or, at least part of the first compensation line 212 overlaps with the second adapter line 311.

[0117] The second main body 2121 and the second connecting portion 2122 may be located in the same conductive layer, that is, the second connecting portion 2122 is arranged in the same layer as the second main body 2121. The second main body 2121 and the second connecting portion 2122 may be an integral structure. The second main body 2121 extending along the first direction x may include that the second main body 2121 extends as a whole along the first direction x in a straight line, a curve, a fold line, or one or more combinations of irregular shapes.

[0118] Since the orthographic projection of the first conductive portion 60 on the substrate 10 is outside the orthographic projection of the first wiring 20 on the substrate 10, in this embodiment, the second connecting portion 2122 is located on one side of the second main body portion 2121 along the second direction y, and the second connecting portion 2122 is connected to the corresponding first-type second wiring 30 through the first via 40, wherein the first-type second wiring 30 corresponding to the second connecting portion 2122 is also the first-type second wiring 30 corresponding to the first compensation line 212. In this way, the position of the first via 40 can be adjusted by setting the second connecting portion 2122, so that the distance between the second via 70 corresponding to the first compensation line 212 connecting the first conductive portion 60 and the second wiring 30 and the first via 40 in the second direction y is small, which is conducive to further improving the brightness uniformity and improving the display effect.

[0119] Fig.15 is a schematic diagram of a partial structure of a display panel provided in an embodiment of the present invention, with reference to Fig.15 In some embodiments, at least one second sub-route 22 overlapping with the second compensation line 312 or the fourth sub-route 32 includes a third main body 221 and a third connecting portion 222, and the third main body 221 extends along the first direction x; the third connecting portion 222 is connected to the third main body 221, and along the second direction y, the third connecting portion 222 is located on one side of the third main body 221; the third connecting portion 222 is connected to the corresponding first-type second route 30 (for example, the second compensation line 312 or the fourth sub-route 32) through the first via 40.

[0120] The third main body portion 221 and the third connecting portion 222 may be located in the same conductive layer, that is, the third connecting portion 222 is arranged in the same layer as the third main body portion 221. The third main body portion 221 and the third connecting portion 222 may be an integral structure. The extension of the third main body portion 221 along the first direction x may include that the third main body portion 221 extends as a whole along the first direction x in a straight line, a curve, a fold line, an irregular shape, or a combination of one or more.

[0121] Since the orthographic projection of the first conductive portion 60 on the substrate 10 is outside the orthographic projection of the first wiring 20 on the substrate 10, in this embodiment, the third connecting portion 222 is located on one side of the third main portion 221 along the second direction y, and the third connecting portion 222 is connected to the corresponding first-type second wiring 30 through the first via 40, wherein the first-type second wiring 30 corresponding to the third connecting portion 222 is also the first-type second wiring 30 corresponding to the second sub-wiring 22. In this way, the position of the first via 40 can be adjusted by setting the third connecting portion 222, so that the distance between the second via 70 corresponding to the second conductive portion 60 and the second wiring 30 of the second sub-wiring 22 and the first via 40 in the second direction y is small, which is conducive to further improving the brightness uniformity and improving the display effect.

[0122] Optionally, along the first direction x, the second connection portion 2122 is equal to the size of the first connection portion 2112, and / or, along the second direction y, the second connection portion 2122 is equal to the size of the first connection portion 2112. In this way, the shielding or reflection effect of the second connection portion 2122 of the first compensation line 212 and the first connection portion 2112 of the first adapter line 211 on light is relatively close, which is beneficial to improving the brightness uniformity in terms of optical performance. In addition, the resistance difference between the second connection portion 2122 of the first compensation line 212 and the first connection portion 2112 of the first adapter line 211 can be reduced, which is beneficial to improving the brightness uniformity of the display panel in terms of electrical performance.

[0123] Optionally, along the first direction x, the third connection portion 222 is equal to the size of the first connection portion 2112, and / or, along the second direction y, the third connection portion 222 is equal to the size of the first connection portion 2112. In this way, the third connection portion 222 of the second sub-line 22 and the first connection portion 2112 of the first adapter line 211 have similar light shielding or reflection effects, which is beneficial to improving brightness uniformity in terms of optical performance. In addition, the resistance difference between the third connection portion 222 of the second sub-line 22 and the first connection portion 2112 of the first adapter line 211 can be reduced, which is beneficial to improving the brightness uniformity of the display panel in terms of electrical performance.

[0124] Optionally, along the first direction x, the third connection portion 222 and the second connection portion 2122 have the same size, and / or, along the second direction y, the third connection portion 222 and the second connection portion 2122 have the same size.

[0125] Optionally, the orthographic projection of the second connection portion 2122 on the substrate 10 overlaps with the orthographic projection of the corresponding first-type second wiring 30 on the substrate 10. In this way, on the one hand, it is convenient for the second connection portion 2122 to be electrically connected to the corresponding first-type second wiring 30 at the overlapping position (that is, the corresponding first overlapping position) through the first via 40, and on the other hand, when the second wiring 30 is on the side of the second connection portion 2122 away from the substrate 10, the second wiring 30 can shield the second connection portion 2122, thereby avoiding the influence of the uneven setting of the second connection portion 2122 on the display effect of the first compensation line 212.

[0126] Optionally, the orthographic projection of the third connection portion 222 on the substrate 10 overlaps with the orthographic projection of the corresponding first-type second wiring 30 on the substrate 10. In this way, on the one hand, it is convenient for the third connection portion 222 to be electrically connected to the corresponding first-type second wiring 30 at the overlapping position (that is, the corresponding first overlapping position) through the first via 40, and on the other hand, when the second wiring 30 is on the side of the third connection portion 222 away from the substrate 10, the second wiring 30 can shield the third connection portion 222, thereby avoiding the influence of the uneven setting of the second connection portion 2122 on the display effect of the first compensation line 212.

[0127] Fig.16 is a schematic diagram of a top view of another display panel provided by an embodiment of the present invention, Fig.17 is a schematic diagram of a top view structure of another display panel provided by an embodiment of the present invention, Fig.18 is a cross-sectional view of another display panel provided by an embodiment of the present invention, Fig.19 is a cross-sectional view of another display panel provided by an embodiment of the present invention, wherein: Fig.18 Can correspond Fig.17 Cut along FF' to get, Fig.19 Can correspond Fig.17 Cut along GG', refer to Figure 16-Figure 19 Optionally, the display panel also includes a third via 80, and the first routing line 20 and the data line Data are arranged in different layers; the first adapter line 211 is electrically connected to the corresponding data line Data through the third via 80; wherein the overlapping position of the first adapter line 211 and the data line Data may be a fourth overlapping position, and the third via 80 is located at the fourth overlapping position of the first adapter line 211 and the data line Data.

[0128] Optionally, along the second direction y, the first via 40 and the third via 80 correspondingly connected to the same first adapter line 211 are located on the same side of the first adapter line 211 or the first main body 2111 of the first adapter line 211 ( Fig.16 shown) or different sides ( Fig.17 situation shown).

[0129] Specifically, the setting of the first via 40 and the third via 80 both requires occupying a certain area. According to the layout space conditions in the display panel, the vias corresponding to the same adapter line can be flexibly arranged to be located on the same side or different sides of the first adapter line 211, thereby making full use of the layout space and facilitating improving the pixel density.

[0130] Optionally, along the second direction y, the second via 70 and the third via 80 corresponding to the same first adapter line 211 are located on the same side or different sides of the first adapter line 211 or the first main body 2111 of the first adapter line 211. In this way, the second via 70 and the third via 80 corresponding to the same first adapter line 211 can be flexibly arranged to be located on the same side or different sides of the first adapter line 211 according to the layout space of the display panel, so as to make full use of the layout space and help improve the pixel density.

[0131] Optionally, the first adapter line 211 includes a first main body 2111 and a fourth connection portion 2113. Along the second direction y, the fourth connection portion 2113 is located at one side of the first main body 2111, and the third via 80 is connected to the fourth connection portion 2113. At least part of the fourth connection portion 2113 may be located at a fourth overlapping position.

[0132] Optionally, the fourth connection portion 2113 and the first main body portion 2111 are arranged at the same layer; in some embodiments, the fourth connection portion 2113 and the first main body portion 2111 are an integral structure.

[0133] Optionally, the orthographic projection of the fourth connection portion 2113 on the substrate 10 overlaps with the orthographic projection of the corresponding data line Data on the substrate 10. In this way, on the one hand, the connection between the fourth connection portion 2113 and the data line Data is convenient; on the other hand, when the data line Data is located on the side of the fourth connection portion 2113 away from the substrate 10, the display defect caused by uneven arrangement of the fourth connection portion 2113 can be improved.

[0134] Optionally, the fourth connection portions 2113 of different first adapter wires 211 have the same size along the second direction y.

[0135] In this way, on the one hand, the resistance of the fourth connection parts 2113 of different first adapter lines 211 is close, which is beneficial to improving the brightness uniformity of the display panel in terms of electrical performance; on the other hand, the difference in the reflection of light by the fourth connection parts 2113 of different first adapter lines 211 is reduced, which is beneficial to improving the brightness uniformity and display effect in terms of optical performance.

[0136] Optionally, the fourth connection portions 2113 of different first adapter lines 211 have the same size along the first direction x. In this way, the brightness uniformity can be improved in terms of both electrical performance and optical performance, further improving the display effect.

[0137] Optionally, along the first direction x, the first via 40 and the third via 80 are staggered, that is, the connection direction of the first via 40 and the third via 80 intersects with the first direction x. Since the first via 40 and the third via 80 will occupy a certain layout space, such a setting can avoid the influence of the first via 40 and the third via 80 being arranged on the same straight line along the first direction x on the pixel density, which is conducive to making full use of the layout space, improving the utilization rate of the layout space, and further improving the pixel density.

[0138] In some embodiments, for the same first trace 20 , a distance d1 between the first trace 20 and the corresponding first via 40 along the second direction y is smaller than a distance d3 between the first trace 20 and the corresponding third via 80 along the second direction y.

[0139] In some other optional embodiments, for the same first routing line 20 , the distance between the first routing line 20 and the corresponding first via 40 along the second direction y is greater than or equal to the distance between the first routing line 20 and the corresponding third via 80 along the second direction y.

[0140] Continue to refer Figure 16-Figure 19 Optionally, the display panel further includes a second conductive portion 90 and a fourth via hole 91. In the thickness direction z of the display panel, the second conductive portion 90 and the first adapter line 211 are located on the same side of the data line Data and are spaced apart. In the second direction y, at least part of the second conductive portion 90 is located on one side of the first adapter line 211, and overlaps with the orthographic projection of at least one data line Data crossed by the first adapter line 211 on the substrate 10, and is connected to the data line Data through the fourth via hole 91 at a fifth overlapping position. The overlapping position of the second conductive portion 90 and the data line Data may be the fifth overlapping position.

[0141] In this embodiment, the display panel further includes a plurality of second conductive parts 90, and the orthographic projection of the second conductive part 90 on the substrate 10 is located outside the orthographic projection of the first adapter line 211 on the substrate 10. Optionally, the second conductive part 90 is insulated from the first adapter line 211. In the thickness direction z of the display panel, the second conductive part 90 and the first adapter line 211 are located on the same side of the data line Data, and the third via 80 of the first adapter line 211 and the data line Data, and the fourth via 91 connecting the second conductive part 90 and the data line Data are both connected to the data line Data from the same side of the data line Data, so that the third via 80 and the fourth via 91 have a closer light shielding or reflection effect on light. For example, the third via 80 and the fourth via 91 have the same shape and / or the same size.

[0142] The first adapter line 211 crossing over at least one data line Data means that at least one data line Data is arranged between the data line Data correspondingly connected to the first adapter line 211 and the second adapter line 311, and the orthographic projection of the data line Data on the substrate 10 overlaps with the orthographic projection of the first adapter line 211 on the substrate 10. For example, the first adapter line 211 may cross over at least one data line Data from above or below.

[0143] In this embodiment, at least part of the second conductive part 90 overlaps with the orthographic projection of at least one data line Data crossed by the first adapter line 211 on the substrate 10, and is connected to the data line Data at the overlapping position through the fourth via hole 91. That is, different from the related art, in the embodiment of the present invention, not only the third via hole 80 is set at the overlapping position of the first adapter line 211 and the corresponding connected data line Data, but also the fourth via hole 91 is set at the overlapping position of the data line Data intersecting and insulated from the first adapter line 211 and the second conductive part 90, so that the via hole setting of the data line Data crossed by the first adapter line 211 can be made closer to the via hole setting of the data line Data correspondingly connected by the first adapter line 211, so that at the positions of the third via hole 80 corresponding to the data line Data correspondingly connected by the first adapter line 211 and the fourth via hole 91 corresponding to the data line Data crossed by the first adapter line 211, the degree of light being blocked or reflected is relatively close, thereby improving the problem of uneven brightness and enhancing the display effect of the display panel.

[0144] Optionally, corresponding to the same first main body 2111, along the second direction y, the fourth via 91 and the third via 80 are located on the same side of the same first main body 2111. In this way, the fourth via 91 and the third via 80 can be relatively closer to the first main body 2111 in the second direction y, which is beneficial to further improve the brightness uniformity and display effect. For example, the fourth via 91 and the third via 80 corresponding to the same first main body 2111 refer to the fourth via 91 and the third via 80 that are adjacent to, close to, or closest to the same first main body 2111.

[0145] For example, the fourth via 91 and the third via 80 corresponding to the same first routing line refer to the fourth via 91 and the third via 80 that are adjacent to, close to, or closest to the same first routing line.

[0146] Optionally, corresponding to the same first body portion 2111, the fourth via hole 91 and the third via hole 80 are located on the same straight line extending along the first direction x. In some embodiments, corresponding to the same first body portion 2111, along the second direction y, the distance d4 between the fourth via hole 91 and the first body portion 2111 is equal to the distance d3 between the third via hole 80 and the first body portion 2111.

[0147] With such an arrangement, the fourth via hole 91 and the third via hole 80 can be positioned at the same position relative to the first main body 2111 along the second direction y, so that the fourth via hole 91 and the third via hole 80 are evenly distributed on the display panel, further improving brightness uniformity and display effect.

[0148] Optionally, the display panel includes multiple via groups corresponding to the same first routing line, for example, each via group includes two adjacent second-type vias, and along the first direction x, the distances between two adjacent second-type vias located on the same straight line in different via groups are equal, and the two adjacent second-type vias include adjacent third vias 80 and fourth vias 91, or two adjacent fourth vias 91, or two adjacent third vias 80. In this way, the second-type vias can be evenly distributed along the first direction x, thereby improving the brightness uniformity in the first direction x and improving the display effect.

[0149] For example, each via group in at least some of the via groups may also include one or at least two first-type vias. The first-type via may include a first via and / or a second via. For example, in a first direction x, a plurality of via groups are arranged, for example, at equal intervals. For example, in a second direction y, a plurality of via groups are arranged, for example, at equal intervals. For example, a plurality of via groups are arranged in an array.

[0150] Optionally, in the second direction y, the distances between different first adapter wires 211 and the corresponding third vias 80 are equal; and / or, in the second direction y, the distances between different first adapter wires 211 and the corresponding fourth vias 91 are equal; wherein the fourth vias 91 corresponding to the first adapter wires 211 include the fourth vias 91 on one side of the data line Data crossed by the first adapter wires 211 in the thickness direction of the display panel. Such an arrangement can make the distribution of the second type of vias more uniform along the second direction y, thereby further improving the brightness uniformity of the display panel and improving the display effect.

[0151] Fig. 20 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Fig. 20 In the above embodiment, Fig.16 and Fig.17 It can correspond to part of the wiring structure in the third display area AA3, combined with Figure 16-Figure 20 Optionally, the first compensation line 212 crosses over at least one data line Data, and at least part of the second conductive portion 90 overlaps with the orthographic projection of the data line Data crossed by the first compensation line 212 on the substrate 10, and along the second direction y, at least part (or at least one) of the second conductive portion 90 is connected to the data line Data through the fourth via 91 on one side of the first compensation line 212, for example, such arrangement is made in the third display area AA3. At least one may include one or more.

[0152] The first compensation line 212 crossing over at least one data line Data means that the orthographic projection of the first compensation line 212 on the substrate 10 overlaps with the orthographic projection of at least one data line Data on the substrate 10. For example, the first compensation line 212 may cross over at least one data line Data from above or below.

[0153] In this way, a fourth via 91 is also set on one side of the first compensation line 212, and the fourth via 91 is also connected to the data line Data, so that the fourth via 91 is also set near the data line Data crossed by the first compensation line 212, further improving the distribution uniformity of the fourth via 91 and the second conductive part 90 in the display panel, so that the via setting conditions near the first compensation line 212 of the first sub-line 21 and the first adapter line 211 are relatively consistent, so that the light reflection conditions at the fourth via 91 on the side of the first compensation line 212 and the fourth via 91 on the side of the first adapter line 211 are relatively consistent. In this way, the brightness uniformity can be further improved, and the brightness unevenness in the screen-off or screen-on state can be improved.

[0154] In some embodiments, the second conductive portion 90 is disposed in the same layer as the first adapter line 211. In this way, the fourth via hole 91 and the third via hole 80 have the same depth, and accordingly, the fourth via hole 91 and the third via hole 80 have more consistent morphologies, so that the light shielding or light reflecting effects of the fourth via hole 91 and the third via hole 80 are more consistent, which can further improve the brightness uniformity.

[0155] refer to Fig. 20 In some embodiments, the second sub-route 22 crosses over at least one data line Data, and at least a portion of the second conductive portion 90 overlaps with the orthographic projection of the data line Data crossed by the second sub-route 22 on the substrate 10, and along the second direction y, at least a portion of the second conductive portion 90 is connected to the data line Data on one side of the second sub-route 22 through the fourth via 91.

[0156] The second sub-route 22 crossing over at least one data line Data means that the orthographic projection of the second sub-route 22 on the substrate 10 overlaps with the orthographic projection of at least one data line Data on the substrate 10. For example, the second sub-route 22 may cross over at least one data line Data from above or below. The second sub-route 22 is located in the fourth display area AA4, and the second sub-route 22 may not be connected to the data signal. In this embodiment, by setting at least a portion of the second conductive portion 90 to overlap with the orthographic projection of the data line Data crossed by the second sub-route 22 on the substrate 10, along the second direction y, at least a portion of the second conductive portion 90 is connected to the data line Data through the second via 70 on one side of the second sub-route 22, so that a fourth via 91 is also set on one side of the second sub-route 22, and the fourth via 91 connects the data line Data and the second conductive portion 90, so that the via setting near the second sub-route 22 is more consistent with the via setting near the first sub-route 21, and the reflection of light near the second sub-route 22 is more consistent with the reflection of light near the first sub-route 21. In this way, the brightness uniformity of the third display area AA3 and the fourth display area AA4 can be made closer, thereby improving the uneven brightness phenomenon when the screen is off or on.

[0157] Continue to refer Figure 16-Figure 20 Optionally, in the third display area AA3, at least one first adapter line 211 crosses over at least one data line Data; along the second direction y, at least one second conductive portion 90 is electrically connected to the data line Data through a fourth via hole 91 on one side of the first adapter line 211.

[0158] Among them, the first adapter line 211 crossing over at least one data line Data means that the orthographic projection of the first adapter line 211 on the substrate 10 overlaps with the orthographic projection of at least one data line Data on the substrate 10. For example, the first adapter line 211 can cross over at least one data line Data from above or below. By setting at least one second conductive portion 90 along the second direction y to be electrically connected to the data line Data through the fourth via 91 on one side of the first adapter line 211, the fourth via 91 is also set near the data line Data crossed by the first adapter line 211, so that the fourth via 91 and the first conductive portion 60 are more evenly distributed in the display panel, further improving the display uniformity in the off-screen or on-screen state, and enhancing the display effect.

[0159] Optionally, the first compensation line 212 and / or the second sub-line 22 are both connected to a fixed voltage or a power supply voltage.

[0160] Continue to refer Figure 16-Figure 20 Optionally, a plurality of data lines Data extend along the second direction y and are arranged along the first direction x; along the first direction x, the second wiring 30 is located between the data lines Data.

[0161] For example, among the three adjacent data lines Data arranged along the first direction x, one or at least two second wirings 30 are arranged between the data line Data in the middle and the data line Data on one side; the second wiring 30 is located outside the area between the data line Data in the middle and the data line Data on the other side. In this way, the data lines Data and the second wirings 30 can be arranged more concentratedly, and there can be enough space between the data line Data in the middle and the data line Data on the other side to arrange the structure of the pixel circuit, which can optimize the layout structure and facilitate the realization of a higher pixel density.

[0162] Optionally, among the three data lines Data arranged and adjacent along the first direction x, at least two second wirings 30 are arranged between the data line Data located in the middle and the data line Data located on one side, and at least two first-type vias corresponding to the at least two second wirings 30 are located on the same side of the two opposite sides along the second direction y of the corresponding first wiring 20, or on both sides. As described in the above embodiment, the first-type vias include the first via 40 and the second via 70.

[0163] like Fig.16 or Fig.17 When at least two first-type vias corresponding to at least two second wirings 30 are located on the same side of the corresponding first wiring 20 on two opposite sides along the second direction y, the first-type vias are arranged evenly, which is beneficial to improving the brightness uniformity of the display panel.

[0164] When at least two first-type vias corresponding to at least two second wirings 30 are located on two sides of the corresponding first wiring 20 that are opposite to each other along the second direction y, each first-type via can have more space for arrangement, thus optimizing the layout structure of the display panel and facilitating the improvement of pixel density. At the same time, the distribution of the first-type vias is also more regularly and evenly distributed, and the brightness uniformity of the display panel is also better.

[0165] In some embodiments, among the three data lines Data arranged and adjacent along the first direction x, at least two second routing lines 30 are arranged between the data line Data located in the middle and the data line Data located on one side (for example, the at least two second routing lines 30 may be arranged in the same layer, or in different layers, for example, located in at least two conductive layers, and an insulating layer is arranged between adjacent conductive layers); at least two first-type vias corresponding to the at least two second routing lines 30 are located on the same side of the two opposite sides of the corresponding first routing line 20 along the second direction y, and are the same or different from the distances from the corresponding first routing line 20 along the second direction y.

[0166] Among them, at least two first-type vias corresponding to at least two second routings 30 are located on the same side of the corresponding first routing 20 on two opposite sides along the second direction y, and are at the same distance from the corresponding first routing 20 along the second direction y. Along the first direction x, each first-type via is located on the same straight line, and the first-type vias are distributed more evenly, further improving the brightness uniformity.

[0167] At least two first-type vias corresponding to at least two second routings 30 are located on the same side of the corresponding first routing 20 on two opposite sides along the second direction y, and are at different distances from the corresponding first routing 20 along the second direction y. On the basis of ensuring that the first-type vias are distributed more evenly, each first-type via has a relatively larger setting space, thereby improving the pixel density of the display panel on the basis of improving the brightness uniformity.

[0168] Optionally, the display panel further includes a plurality of power lines VDD, which extend along the second direction y and are arranged along the first direction x; along the first direction x, the power lines VDD are located between the data lines Data; and data lines Data are arranged between adjacent power lines VDD and the second wiring 30 .

[0169] Optionally, among the three data lines Data arranged and adjacent to each other along the first direction x, one side of the middle data line Data is the second wiring 30, and the other side of the middle data line Data is the power line VDD. This arrangement makes the second wiring 30 more evenly distributed in the display panel, and correspondingly, the first type of vias are more evenly distributed, thereby improving the brightness uniformity of the display panel.

The first via 40 is located at the intersection of the first adapter line 211 and the second adapter line 311. The first adapter line 211 does not need to include the first connection portion 2112, so that the space occupied by the first adapter line 211 can be reduced, saving the wiring space of the first adapter line 211, which is conducive to improving the pixel density.

In this way, the second vias 70 can be evenly arranged to improve brightness uniformity.

[0179] For example, the distribution rules of the first vias, second vias, third vias, and fourth vias corresponding to different first routings are the same or similar.

Optionally, the display panel may not be provided with a second avoidance line segment.

[0194] Optionally, the second avoidance line segment partially surrounds the first sub-area AA51. In this way, the edge shape of the second avoidance line segment is relatively consistent with that of the first sub-area AA51, so that the second avoidance line segment occupies a smaller layout space, optimizes the wiring structure of the layout, and thus ensures a higher pixel density.

[0195] Optionally, the first sub-area AA51 includes a light-transmitting hole. The light-transmitting hole may be a via hole in the display panel that allows ambient light to pass through, and may be an ambient light hole. The light-transmitting hole may be circular, elliptical, rectangular, rounded rectangular, polygonal, etc. In some embodiments, in the fifth display area AA5, the conductive layer in the display panel is located in the second sub-area AA52; for example, one or more of the first wiring 20, the second wiring 30, and the data line Data are located in the conductive layer. In this way, the conductive layer is not provided in the first display sub-area to avoid shielding of the ambient light by the conductive layer.

[0196] Optionally, in the fifth display area AA5, the insulating layer between the conductive layers in the display panel is located in the second sub-area AA52.

Correspondingly, setting the first via hole 40 and / or the second via hole 70 in the third sub-area AA61 has little effect on the light transmittance performance of the display panel. In the related art, light-transmitting holes are usually set on the entire surface of the display area, and the third display area AA3 in the sixth display area AA6 corresponds to the setting area of ​​the light-transmitting holes in the related art. In the present embodiment, light-transmitting holes are set only in the fifth display area AA5, and no light-transmitting holes are set in the sixth display area AA6, so that the first via hole 40 and / or the second via hole 70 can be set in the third sub-area AA61 of the sixth display area AA6 corresponding to the light-transmitting hole area, thereby optimizing the layout structure of the display panel, making full use of the layout space, and thus improving the pixel density.

Fig.26 In some other embodiments, in the third sub-area AA61, the pixel definition layer 140 has a continuous structure. Optionally, the pixel definition layer 140 is opaque or black.

Fig.23 In some other embodiments, in the third sub-area AA61, the black matrix 161 has a continuous structure.

[0216] Based on the above embodiments, Figure 8 and Fig. 9 Optionally, the display panel includes a plurality of conductive layers stacked on the substrate, and the first conductive portion 60 and the first adapter line 211 are located on the same conductive layer. In this way, the first via 40 and the second via 70 are connected to the same conductive layer, so that the light shielding and / or light reflecting effects of the first via 40 and the second via 70 are more consistent, further improving the brightness uniformity of the display panel.

[0217] Optionally, the second wiring 30 and the data line Data are located in the same conductive layer. In this way, the second wiring 30 and the data line Data can be prepared in the same process step, simplifying the preparation process of the display panel. At the same time, it is helpful to reduce the thickness of the display panel. For example, the power line VDD and the data line Data are located in the same conductive layer. For example, the power line VDD and the second wiring 30 are located in the same conductive layer.

[0218] Optionally, the first wiring 20 is located in the first conductive layer 131, the second wiring 30 is located in the second conductive layer 132, and the first conductive layer 131 is located on the side of the second conductive layer 132 close to or away from the substrate 10. In some embodiments, the display panel further includes a first planarization layer, and the first planarization layer is located between the first conductive layer 131 and the second conductive layer 132. The thickness of the first planarization layer is relatively large, so that the arrangement of the conductive portion or the first wiring 20 in the first conductive layer 131 will not affect the flatness of the surface of the first planarization layer away from the substrate 10. In this way, the morphology of the wiring in the second conductive layer 132 is almost the same, so that the shading and / or reflection effect of the wiring in the second conductive layer 132 is more consistent, further improving the display uniformity. The first planarization layer may include an organic material, such as an organic insulating material. The conductive layer may include a metal or a metal oxide or a light-transmitting conductive material. For example, the conductive layer may include a titanium layer / aluminum layer / titanium layer stacked in sequence, or the conductive layer may include indium tin oxide (ITO).

[0219] Continue to refer Fig.21 Optionally, the display area includes a third display area AA3 and a fourth display area AA4, and the fourth display area AA4 is located on a side of the binding pin away from the third display area AA3.

In this way, the first type of via holes including the first via hole 40 and the second via hole 70 are evenly arranged in the first direction x and the second direction y, thereby improving the brightness uniformity of the display panel.

[0222] Each routing line (first routing line, second routing line, sub-routing line, data line, power line) etc. may extend along its own extension direction in a straight line, a curve, a broken line, an irregular shape or a combination of one or more shapes.

Among them, the first sub-area AA51 can be used to set an optical sensor. The optical sensor may include a camera, a fingerprint recognition module, an ambient light detection module, an infrared sensor, etc.

[0224] For example, the display panel also includes multiple power lines VDD. Among the three adjacent data lines Data, the first sub-area AA51 is set between the data line Data located in the middle and one of the sides, and the power line VDD is set between the data line Data located in the middle and the other side. For example, the first sub-area AA51 is located outside the area between the data line Data in the middle and the other side, for example, the power line VDD is located outside the area between the data line Data in the middle and one of the sides.

[0225] In the display panel of this embodiment, the first sub-area AA51 and the power line VDD are arranged alternately between different data lines Data, which can make the first sub-area AA51 distributed more evenly so that the optical sensor can receive light evenly. On the other hand, the layout structure of the display panel can be optimized to make full use of the layout space.
