[0034] 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.

[0035] 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.

[0036] As described in the background technology, the existing display panel has the problem of picture display uniformity, which affects the display effect of the display panel. The inventors have found that the reason for the above problem is that the existing display panel includes a variety of signal lines, and the signal lines receive signals from the non-display area of ​​the display panel and transmit the signals to the pixel circuits in the display area. However, due to the resistance of the signal lines themselves, the signals received by the pixel circuits at different positions in the display panel are quite different, resulting in poor display uniformity of the display panel, which ultimately affects the display effect of the display panel.

[0037] Based on the above reasons, an embodiment of the present invention provides a display panel. Figure 1 is a partial top view structural diagram of a display panel provided by an embodiment of the present invention, Figure 2 is a partial top view of another display panel provided by an embodiment of the present invention, Figure 3 is a partial top view of another display panel provided by an embodiment of the present invention, with reference to Figure 1-Figure 3 The display panel includes at least two conductive layers stacked on a substrate, and the at least two conductive layers are provided with a first mesh structure 100 and a second mesh structure 200; the first mesh structure 100 includes at least one sub-mesh structure, and the sub-mesh structure includes a plurality of first sub-signal lines 110 and a plurality of second sub-signal lines 120, and the first sub-signal lines 110 and the second sub-signal lines 120 are located in different conductive layers; the first sub-signal lines 110 extend along a first direction y, and the plurality of second sub-signal lines 120 extend along a second direction x and are arranged along the first direction y, and the first direction y and the second direction x intersect, for example, perpendicularly; the second mesh structure 200 includes a plurality of third sub-signal lines 210 and a plurality of connecting portions 220, and the third sub-signal lines 210 extend along the first direction y and Arranged along the second direction x, the third sub-signal line 210 and the connecting portion 220 are both located in the same conductive layer as the first sub-signal line 110; wherein, at least some of the first sub-signal lines 110 include a plurality of continuous portions 111 arranged along the first direction y, with breaks 112 between the continuous portions 111, the connecting portion 220 passes through the breaks 112, and is electrically connected to the third sub-signal line 210 on both sides of the first sub-signal line 110 respectively; in the same sub-network structure, among the plurality of continuous portions, the orthographic projection of each of the continuous portions 111 in at least some of the continuous portions 111 (i.e., one or more continuous portions 111) on the substrate overlaps with the orthographic projection of each of the at least two adjacent second sub-signal lines 120 on the substrate, and are electrically connected at the overlapping position.

[0038] Among them, the conductive layer may include at least one of an active layer, a metal layer and a metal oxide layer. At least two conductive layers are stacked on the substrate, and an insulating layer is arranged between different conductive layers. A first mesh structure 100 and a second mesh structure 200 are arranged in at least two conductive layers. The first mesh structure 100 and the second mesh structure 200 can be used for signal transmission, that is, the first mesh structure 100 and the second mesh structure 200 can also be used as signal lines in the display panel respectively. In some optional embodiments of the present invention, the first mesh structure 100 and the second mesh structure 200 are used to transmit different signals, and accordingly, the first mesh structure 100 and the second mesh structure 200 are insulated to avoid the first mesh structure 100 and the second mesh structure 200 from short-circuiting and affecting the display of the display panel.

[0039] The first mesh structure 100 includes at least one sub-mesh structure, each of which may include a plurality of first sub-signal lines 110 and a plurality of second sub-signal lines 120, the first sub-signal lines 110 and the second sub-signal lines 120 are located in different conductive layers, the extension directions of the first sub-signal lines 110 and the second sub-signal lines 120 intersect, and the first sub-signal lines 110 and the second sub-signal lines 120 are electrically connected at least partially intersecting positions, so that the first sub-signal lines 110 and the second sub-signal lines 120 form a signal line of a mesh structure. In this way, the resistance of the sub-mesh structure can be made smaller, so that the voltage drop of the signal transmitted by the sub-mesh structure is relatively small, which is conducive to improving the display uniformity of the display panel. Different sub-mesh structures can transmit the same signal or different signals, which is not specifically limited in this embodiment.

[0040] The second mesh structure 200 includes a plurality of third sub-signal lines 210 and a plurality of connecting portions 220. The third sub-signal lines 210 and the first sub-signal lines 110 in the first mesh structure 100 extend in the same direction. Both extend in the first direction y, and both are arranged along the second direction x. In this embodiment, at least some of the first sub-signal lines 110 are intermittently arranged. Specifically, at least some of the first sub-signal lines 110 include a plurality of continuous portions 111 arranged along the first direction y, and there are breaks 112 between the continuous portions 111, that is, at least some of the first sub-signal lines 110 may be discontinuous signal lines, and the breaks 112 between the continuous portions 111111 may be passed through by the connecting portions 220 of the second mesh structure 200, and the connecting portions 220 pass through the breaks 112 and connect to the third sub-signal lines on both sides of the first sub-signal lines 110. The third sub-signal lines 210 and the connecting parts 220 are electrically connected to each other, so that different third sub-signal lines 210 extending along the first direction y can be electrically connected in the second direction x through the connecting parts 220, and different connecting parts 220 can also be electrically connected in the first direction y through the third sub-signal lines 210, so that multiple third sub-signal lines 210 and multiple connecting parts 220 form a second mesh structure 200, so that the second mesh structure 200 has a relatively small resistance, reduces the signal transmission voltage drop of the second mesh structure 200, and improves display uniformity. Among them, the third sub-signal lines 210 and the connecting parts 220 are all located in the same conductive layer as the first sub-signal lines 110, so that the number of conductive layers set in the display panel can be relatively small, which can reduce the thickness of the display panel on the one hand, and on the other hand, the third sub-signal lines 210 and the connecting parts 220 can be formed in the same process steps as the first sub-signal lines 110, which can simplify the preparation process of the display panel.

[0041] In the present embodiment, in the same sub-mesh structure, the orthographic projection of each continuous portion 111 in at least one continuous portion 111 on the substrate overlaps with the orthographic projection of each second sub-signal line 120 in at least two adjacent second sub-signal lines 120 on the substrate, and is electrically connected at the overlapping position, so that the two adjacent second sub-signal lines 120 can be electrically connected to the same continuous portion 111, ensuring that the two second sub-signal lines 120 extending along the second direction x of the continuous portion 111 can be electrically connected in the first direction y through the continuous portion 111, and the first sub-signal line 110 extending along the first direction y can also be electrically connected in the second direction x through the second sub-signal line 120, thereby allowing the first sub-signal lines 110 and the second sub-signal lines 120 to form a mesh structure, so that the sub-mesh structure in the first mesh structure 100 has a relatively small resistance, reducing the signal transmission voltage drop of the sub-mesh structure in the first mesh structure 100, and improving display uniformity.

[0042] In the display panel of the present embodiment, in the sub-net structure in the first net structure, at least part of the first sub-signal lines include a plurality of continuous parts arranged along the first direction, and there are breaks between the continuous parts. The breaks between the continuous parts can be passed through by the connecting parts of the second net structure, and the connecting parts pass through the breaks to be electrically connected to the third sub-signal lines on both sides of the first sub-signal lines, so that the plurality of third sub-signal lines and the plurality of connecting parts form a second net structure, so that the second net structure has a relatively small resistance, reduces the signal transmission voltage drop of the second net structure, and improves the display uniformity. In the same sub-net structure, the positive projection of each continuous part in at least one continuous part on the substrate overlaps with the positive projection of each second sub-signal line in at least two adjacent second sub-signal lines on the substrate, and is electrically connected at the overlapping position, so that the first sub-signal line and the second sub-signal line form a sub-net structure, so that the sub-net structure in the first net structure has a relatively small resistance, reduces the signal transmission voltage drop of the sub-net structure in the first net structure, improves the display uniformity, and thus improves the display effect. In addition, the third sub-signal line and the connecting part are both located in the same conductive layer as the first sub-signal line, so that the number of conductive layer layers in the display panel can be relatively small. On the one hand, the thickness of the display panel can be reduced. On the other hand, the third sub-signal line and the connecting part can be formed in the same process steps as the first sub-signal line, which can simplify the preparation process of the display panel.

[0043] Each signal line or routing line may extend in a straight line, a curve, a folded line, an irregular shape (such as a tree branch) or a combination of the above, and the embodiment of the present invention is not limited to this.

[0044] In some optional embodiments of the present invention, in the same sub-network structure, every two adjacent second sub-signal lines 120 are electrically connected through a continuous portion 111 or a plurality of continuous portions 111 arranged along the second direction x. In this way, in the display panel, each second sub-signal line 120 can be electrically connected in the first direction y through the continuous portion 111, so that the network range of the sub-network structure in the display panel is larger, which is equivalent to increasing the cross-sectional area of ​​the sub-network structure along the second direction x, further reducing the resistance of the sub-network structure, and further improving the display uniformity. The more continuous portions 111 there are, the more it is beneficial to increase the number of fractures and connecting portions, and thus to reduce the impedance of the second network structure. However, the number of continuous portions 111 cannot be too much, which is not conducive to reducing the impedance of the sub-network structure. Therefore, the number of continuous portions 111 is reasonably set according to needs.

[0045] Optionally, in the same sub-network structure, the length of at least one continuous portion 111 along the first direction y is greater than or equal to the spacing between two adjacent second sub-signal lines 120; in this way, it can be ensured that the orthographic projection of at least one continuous portion 111 on the substrate overlaps with the orthographic projection of each of the at least two adjacent second sub-signal lines 120 on the substrate, so that the continuous portion 111 and the two adjacent second sub-signal lines 120 can form an electrical connection at the overlapping position, ensuring that the second sub-signal line 120 and the first sub-signal line 110 can form a sub-network structure. In this embodiment, there is no need to set or reduce the setting of jumpers set at different layers from the continuous portion, and the jumpers and the continuous portion are connected through vias, and the adjacent second sub-signal lines 120 are connected through the jumpers and the continuous portion, thereby reducing the wiring complexity, reducing the number of vias set, reducing the occupied space, and facilitating the improvement of pixel density. No jumpers or vias connected to the continuous portion are set at the break.

[0046] In some optional embodiments of the present invention, one or more breaks 112 are provided between two adjacent third signal sub-lines 210. Optionally, two adjacent third signal sub-lines 210 are connected via one connection portion 220 or multiple connection portions 220 arranged along the first direction y.

[0047] Specifically, a first sub-signal line 110 may be provided between two adjacent third sub-signal lines 210, and one or more breaks 112 may be provided on the first sub-signal line 110 between two adjacent third sub-signal lines 210, thereby providing space for the arrangement of the connection portion 220. Two adjacent third sub-signal lines 210 are connected by one connection portion 220, or two adjacent third sub-signal lines 210 are connected by multiple connection portions 220, and the multiple connection portions 220 are arranged along the first direction y. In this way, each third sub-signal line 210 in the display panel can be electrically connected in the second direction x through the connection portion 220, so that the second mesh structure 200 has a larger mesh range in the display panel, which is equivalent to increasing the cross-sectional area of ​​the second mesh structure 200 along the first direction y, further reducing the resistance of the second mesh structure 200, and further improving the display uniformity.

[0048] Optionally, along the second direction x, the first sub-signal lines 110 and the third sub-signal lines 210 are arranged alternately. In this way, the first sub-signal lines 110 and the third sub-signal lines 210 in the display panel can be evenly distributed, so that the distribution density of the first sub-signal lines 110 in the sub-mesh structure in the first mesh structure 100 and the third sub-signal lines 210 in the second mesh structure 200 is relatively consistent, so that the signal transmission voltage drop of the sub-mesh structure is relatively uniform and the signal transmission voltage drop of the second mesh structure 200 is relatively uniform, which is conducive to further improving the display uniformity of the display panel.

[0049] Optionally, the first sub-signal line 110 and the second sub-signal line 120 are initialization signal lines Vref; and / or, the third sub-signal line 210 is a power line VDD.

[0050] Optionally, the display panel further includes a plurality of pixel circuits. Figure 4 is a schematic structural diagram of a pixel circuit provided by an embodiment of the present invention, Figure 5 is a schematic diagram of another pixel circuit provided by an embodiment of the present invention, referring to Figure 4 and Figure 5 The display panel includes a plurality of pixel circuits and a plurality of light emitting devices 320, wherein the pixel circuit includes a driving module 310. The pixel circuit also includes an initialization module 301, which is used to initialize at least one of the first end, the second end and the control end of the driving module 310 and the first pole of the light emitting device 320, and the initialization module 301 is electrically connected to the initialization signal line Vref. For example, the initialization module 301 is electrically connected to the sub-net structure in the first net structure 100.

[0051] refer to Figure 4The initialization module 301 of the pixel circuit includes a first initialization module 330 and / or a second initialization module 340. The driving module 310 is used to generate a driving current to drive the corresponding light-emitting device 320. The first initialization module 330 is electrically connected to the control end of the driving module 310, and is used to initialize the control end of the driving module 310. The second initialization module 340 is electrically connected to the first electrode of the light-emitting device, and is used to initialize the first electrode of the light-emitting device 320. The first mesh structure is electrically connected to the first initialization module 330 and / or the second initialization module 340. The driving module 310 is electrically connected between the third sub-signal line 210 and the first electrode of the light-emitting device 320. Figure 5 The initialization module 301 may further include a third initialization module 350, which is electrically connected to the first end or the second end of the driving module 310 and is used to initialize the first end or the second end of the driving module 310. Figure 5 The diagram schematically shows the connection between the third initialization module 350 and the first end of the driving module 310. The first sub-signal line 110 and the second sub-signal line 210 of the sub-network structure serve as the initialization signal line Vref, which can be electrically connected to the first initialization module 330 to provide an initialization signal for the first initialization module 330; the first sub-signal line 110 and the second sub-signal line 120 of the sub-network structure serve as the initialization signal line Vref, which can also be electrically connected to the second initialization module 340 to provide an initialization signal for the second initialization module 340; the first sub-signal line 110 and the second sub-signal line 210 of the sub-network structure serve as the initialization signal line Vref, which can be electrically connected to the third initialization module 350 to provide an initialization signal for the third initialization module 350. The initialization signal corresponding to the first initialization module 330 and the initialization signal corresponding to the second initialization module 340 can be the same or different. Figure 1 , Figure 4 and Figure 5 When the same sub-network structure is electrically connected to the first initialization module 330 and the second initialization module 340, the sub-network structure serves as the initialization signal line Vref. Figure 2 , Figure 4 and Figure 5 When the first mesh structure 100 includes a first sub-mesh structure 101 and a second sub-mesh structure 102, the first sub-mesh structure 101 is electrically connected to the first initialization module 330 as a first initialization signal line Vref1, and the second sub-mesh structure 102 is electrically connected to the second initialization module 340 as a second initialization signal line Vref2.

[0052] In the case where the pixel circuit includes the third initialization module 350, one of the first sub-network structure 101 and the second sub-network structure 102 may be connected to one or more of the first initialization module 330, the second initialization module 340 and the third initialization module 350, and the other of the first sub-network structure 101 and the second sub-network structure 102 may be connected to another one or more of the first initialization module 330, the second initialization module 340 and the third initialization module 350. For example, the third initialization module 350 is electrically connected to the first sub-network structure 101 or the second sub-network structure 102. The first network structure may further include a third sub-network structure, and the third sub-network structure is electrically connected to the third initialization module 350 as a third initialization signal line Vref3.

[0053] In other optional embodiments of the present invention, when the pixel circuit does not include the third initialization module, the first initialization module is electrically connected to the control end, the first end or the second end of the driving module for initializing the control end, the first end or the second end of the driving module.

[0054] Continue to refer Figure 1-Figure 3 Optionally, the connection parts 220 are arranged in one-to-one correspondence with the break 112, and the connection parts 220 pass through the corresponding break 112 to be electrically connected to the third sub-signal lines 210 on both sides of the first sub-signal line 110. In this way, it can be ensured that the break 112 of the first sub-signal line 110 can be fully utilized, so that the number of the connection parts 220 is large, and the resistance of the second mesh structure 200 is further reduced, thereby further improving the display uniformity.

[0055] In some optional embodiments of the present invention, among the plurality of first sub-signal lines, the breaks 112 corresponding to each first sub-signal line 110 in some of the first sub-signal lines 110 are arranged at equal intervals along the first direction y. That is, the breaks 112 corresponding to each first sub-signal line 110 in one or more first sub-signal lines 110 are arranged at equal intervals along the first direction y. In this way, the breaks 112 corresponding to at least one sub-signal line can be arranged evenly along the first direction y, so that the resistance of the sub-mesh structure along the first direction y is relatively uniform, which is conducive to further improving the display uniformity of the display panel in the first direction y.

[0056] Optionally, among at least two first sub-signal lines 110, the spacing between adjacent breaks 112 corresponding to one first sub-signal line 110 along the first direction y is equal to the spacing between adjacent breaks 112 corresponding to another first sub-signal line 110 along the first direction y. That is, the spacing between adjacent breaks 112 corresponding to different first sub-signal lines 110 among at least two first sub-signal lines 110 along the first direction y is equal. In this way, the breaks 112 in the sub-network structure can be evenly arranged along the second direction x, so that the resistance of the sub-network structure along the second direction x is relatively uniform, which is conducive to further improving the display uniformity of the display panel in the second direction x.

[0057] Optionally, the connection parts 220 electrically connected to two adjacent third sub-signal lines 210 are arranged at equal intervals along the first direction y. That is, the connection parts 220 electrically connected to two adjacent third sub-signal lines 210 are arranged at equal intervals along the first direction y. In this way, the connection parts 220 in the second mesh structure 200 can be evenly distributed in the first direction y, so that the resistance of the second mesh structure 200 in the first direction y is relatively uniform, which is conducive to further improving the display uniformity of the display panel in the first direction y.

[0058] In some optional embodiments of the present invention, in the same sub-network structure, the breaks 112 corresponding to two adjacent first sub-signal lines 110 are staggered in the second direction x; in this way, the continuous portion 111 of one of the two adjacent first sub-signal lines 110 can be connected to the first two second sub-signal lines 120 of the three adjacent second sub-signal lines 120, and the continuous portion 111 of the other can be connected to the last two second sub-signal lines 120 of the three adjacent second sub-signal lines 120; or, the continuous portion 111 of one of the two adjacent first sub-signal lines 110 can be connected to the last two second sub-signal lines 120 of the three adjacent second sub-signal lines 120, and the continuous portion 111 of the other can be connected to the first two second sub-signal lines 120 of the three adjacent second sub-signal lines 120, and then the three adjacent second sub-signal lines 120 can be electrically connected in the first direction y through the two adjacent first sub-signal lines 110, so that the first sub-signal lines 110 and the second sub-signal lines 120 can form a network structure.

[0059] In some optional embodiments of the present invention, in the same sub-network structure, the breaks 112 corresponding to two adjacent first sub-signal lines 110 are staggered in the first direction y.

[0060] For example, the distance between adjacent breaks on the same first sub-signal line in the first sub-network structure in the first direction is equal to the distance between adjacent breaks on the same first sub-signal line in the second sub-network structure in the first direction. For example, the length of the continuous portion of the same first sub-signal line in the first sub-network structure in the first direction is equal to the length of the continuous portion of the same first sub-signal line in the second sub-network structure in the first direction.

[0061] Specifically, the second sub-signal lines 120 may be numbered sequentially along the first direction y. For example, along the first direction y, the second sub-signal lines 120 are numbered 1, 2, 3, ... For any three adjacent second sub-signal lines 120, any three adjacent second sub-signal lines 120 may represent the i-1th second sub-signal line 120, the i-th second sub-signal line 120, and the i+1th second sub-signal line 120. Figure 1 In some optional embodiments of the present invention, in the same sub-mesh structure, among two adjacent first sub-signal lines 110, the break 112 corresponding to one first sub-signal line 110 is located between the i-1th second sub-signal line 120 and the i-th second sub-signal line 120, and the break 112 corresponding to the other first sub-signal line 110 is located between the i-th second sub-signal line 120 and the i+1th second sub-signal line 120, wherein i is an integer greater than or equal to 2, and the serial numbers of adjacent second sub-signal lines 120 are adjacent. In this way, among two adjacent first sub-signal lines 110, the continuous portion 111 of one of the first sub-signal lines 110 can form an electrical connection between the i-1th second sub-signal line 120 and the i-th second sub-signal line 120 in the first direction y, and the continuous portion 111 of the other first sub-signal line 110 can form an electrical connection between the i-th second sub-signal line 120 and the i+1th second sub-signal line 120 in the first direction y, and the two adjacent first sub-signal lines 110 can also form an electrical connection in the second direction x through the three adjacent second sub-signal lines 120. In this way, any two adjacent first sub-signal lines 110 and any three adjacent first sub-signal lines 110 can form an electrical connection in the first direction y, and can also form an electrical connection in the second direction x, so that the grid of the sub-mesh structure is dense and uniform, which is beneficial to further reduce the resistance of the sub-mesh structure, and further improve the display uniformity of the display panel.

[0062] In some optional embodiments of the present invention, in the same sub-mesh structure, among the three adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 on both sides are located between the i-1th second sub-signal line 120 and the i-th second sub-signal line 120, and outside the i-th second sub-signal line 120 and the i+1th second sub-signal line 120.

[0063] In another optional embodiment of the present invention, in the same sub-mesh structure, among the three adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 on both sides are located between the i-th second sub-signal line 120 and the i+1-th second sub-signal line 120, and outside the i-1-th second sub-signal line 120 and the i-th second sub-signal line 120.

[0064] Continue to refer Figure 1-Figure 3 In some optional embodiments of the present invention, in the same sub-network structure, among the adjacent k first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 on both sides are relatively arranged along the second direction x, and k is an integer greater than or equal to 3.

[0065] For example, Figure 1 and Figure 2 In the display panel shown, k=3, then in the three first sub-signal lines 110 adjacent to each other along the second direction in the same sub-network structure, the breaks 112 corresponding to the first first sub-signal line 110 and the third first sub-signal line 110 are arranged opposite to each other along the second direction x. Figure 3 In the display panel shown, k=5, then among the five first sub-signal lines 110 adjacent along the second direction in the same sub-network structure, the breaks 112 corresponding to the first first sub-signal line 110 and the fifth first sub-signal line 110 are arranged relatively along the second direction x. In the same sub-network structure, among the k adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 located on both sides are arranged relatively along the second direction x, which may mean that among the k adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 located on both sides have the same coordinate positions in the first direction y, so that the distribution of the breaks 112 corresponding to the first sub-signal lines 110 in the display panel can be more uniform, which is beneficial to further improve the display uniformity of the display panel.

[0066] Figure 6 is a partial top view of another display panel provided by an embodiment of the present invention, Figure 7 is a partial top view of another display panel provided by an embodiment of the present invention, referring to Figure 6 and Figure 7In some other optional embodiments of the present invention, in the same sub-mesh structure, among the k adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 located on both sides are located between the same adjacent second sub-signal lines 120; for example, in the same sub-mesh structure, among the k adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 located on both sides are located between the same two adjacent second sub-signal lines 120. In the same sub-network structure, among the k adjacent first sub-signal lines 110, the first sub-signal lines 110 located between the first sub-signal lines 110 on both sides, and the breaks 112 corresponding to any two of the first sub-signal lines 110 located on one side are staggered in the second direction x; in this way, it can be made that in the same sub-network structure, among the k adjacent first sub-signal lines 110, the breaks 112 corresponding to the first sub-signal lines 110 located between the first sub-signal lines 110 on both sides, and the breaks 112 corresponding to the first sub-signal lines 110 located on one side can be between two different second sub-signal lines 120, and further, among the k adjacent first sub-signal lines 110, the first sub-signal lines 110 located between the first sub-signal lines 110 on both sides can electrically connect the two second sub-signal lines 120 on both sides of the breaks 112 corresponding to the first sub-signal lines 110 on both sides in the first direction y, thereby forming a sub-network structure.

[0067] Optionally, in the same sub-mesh structure, among the adjacent k first sub-signal lines 110 , the breaks 112 corresponding to any two of the first sub-signal lines 110 located between the first sub-signal lines 110 on both sides and the first sub-signal lines 110 located on one side are staggered in the first direction y.

[0068] Optionally, in the same sub-mesh structure, among three adjacent first sub-signal lines 110, the misalignment distance of the breaks 112 corresponding to the two first sub-signal lines 110 located on one side and in the middle is equal to the misalignment distance of the breaks 112 corresponding to the two first sub-signal lines 110 located on the other side and in the middle.

[0069] That is, in the same sub-mesh structure, among the three adjacent first sub-signal lines 110, the misalignment distance of the breaks 112 corresponding to the first first sub-signal line 110 and the second first sub-signal line 110 is equal to the misalignment distance of the breaks 112 corresponding to the third first sub-signal line 110 and the second first sub-signal line 110, and the misalignment distance is the misalignment distance in the first direction y. In this way, the uniformity of the distribution of the breaks 112 in the display panel can be further improved, thereby improving the display uniformity.

[0070] Continue to refer Figure 2 , Figure 3 and Figure 7Optionally, at least one sub-mesh structure includes a first sub-mesh structure 101 and a second sub-mesh structure 102 that are insulated; the first sub-signal lines 110 in the first sub-mesh structure 101 and the first sub-signal lines 110 in the second sub-mesh structure 102 are alternately arranged along the second direction x; the second sub-signal lines 120 in the first sub-mesh structure 101 and the second sub-signal lines 120 in the second sub-mesh structure 102 are alternately arranged along the first direction y.

[0071] The first sub-mesh structure 101 and the second sub-mesh structure can transmit different signals. By setting the first sub-signal line 110 of the first sub-mesh structure 101 and the first sub-signal line 110 in the second sub-mesh structure 102 to be arranged alternately along the second direction x; the second sub-signal line 120 in the first sub-mesh structure 101 and the second sub-signal line 120 in the second sub-mesh structure 102 to be arranged alternately along the first direction y, the first sub-signal line 110 in the first sub-mesh structure 101 and the first sub-signal line 110 in the second sub-mesh structure can be distributed more evenly in the display panel, and the second sub-signal line 120 in the first sub-mesh structure 101 and the second sub-signal in the second sub-mesh structure can be distributed more evenly in the display panel, and the resistance distribution of the first sub-mesh structure 101 and the second sub-mesh structure in the first direction y and the second direction x can be uniform, which is conducive to further improving the display uniformity of the display panel.

[0072] For example, the first sub-signal line 110 in the first sub-mesh structure 101 and the first sub-signal line 110 in the second sub-mesh structure 102 may be disposed in the same layer or in different layers.

[0073] In some optional embodiments, the first sub-signal line 110 in the adjacent first sub-mesh structure 101 and the corresponding break 112 of the first sub-signal line 110 in the second sub-mesh structure 102 are staggered in the second direction x; in this way, the connection portion 220 passing through the first sub-signal line 110 and the connection portion 220 passing through the second sub-signal line 120 can be staggered in the second direction x, which can make the distribution of the connection portion 220 in the display panel more uniform, thereby making the resistance distribution of the second mesh structure 200 more uniform, which is conducive to further improving the display uniformity of the display panel. In some optional embodiments of the present invention, the first sub-signal line 110 in the adjacent first sub-mesh structure 101 and the corresponding break 112 of the first sub-signal line 110 in the second sub-mesh structure 102 are staggered in the first direction y, further increasing the distribution uniformity of the connection portion 220 in the display panel, and further improving the display uniformity.

[0074] Figure 8 is a partial top view of another display panel provided by an embodiment of the present invention, referring to Figure 8In another optional embodiment of the present invention, the breaks 112 corresponding to the first sub-signal lines 110 in the adjacent first sub-mesh structures 101 and the first sub-signal lines 110 in the second sub-mesh structures 102 are arranged relatively to each other in the second direction x; in this way, two adjacent connecting portions 220 along the second direction x can be directly electrically connected, so that the transmission resistance of the second mesh structure 200 corresponding to the pixel circuits located in the same row on both sides of the same third sub-signal line 210 is more consistent, which is beneficial to further improve the display uniformity.

[0075] Fig. 9 is a partial top view of another display panel provided by an embodiment of the present invention, Fig.10a It is a partial top view structural schematic diagram of another display panel provided by an embodiment of the present invention.

In this way, the breaks 112 can be evenly distributed in the display panel, and accordingly, the connecting portion 220 can be evenly distributed in the display panel, and the first sub-signal line 110, the second sub-signal line 120 of the sub-mesh structure, and the third sub-signal line 210 in the second mesh structure 200 are evenly distributed in the display panel, so that the resistance of the first mesh structure 100 and the second mesh structure 200 is evenly distributed, thereby improving the display uniformity of the display panel. Among them, Fig. 9 and Figure 1 The display panels shown have the same structure, but the structure of the line repeating unit 10 is different. Fig. 9 The line repeating unit 10 in the display panel structure shown can be composed of Figure 1 The display panel structure shown is obtained by translating the line repeating unit 10 downward; wherein, Fig.10a and Figure 2 The display panels shown have the same structure, but the structure of the line repeating unit 10 is different. Fig.10a The line repeating unit 10 in the display panel structure shown can be composed of Figure 2 The display panel structure shown is obtained by translating the line repeating unit 10 downward. Fig.10b and Figure 2 The display panels shown have the same or similar structures, but the structure of the line repeating unit 10 is different. Fig.10b The line repeating unit 10 in the display panel structure shown can be composed of Figure 2 The line repeating unit 10 in the display panel structure shown is obtained by translating downward a sub-area by a distance corresponding to the length of the first direction y. Those skilled in the art can divide the line repeating unit 10 according to actual needs, and the present invention does not make any specific limitation here.

[0076] Continue to refer Figure 1-Figure 3 as well as Figure 6-10a Optionally, a plurality of line repetition units 10 are arranged in an array, the column direction of the array is parallel to the first direction y, and the row direction of the array is parallel to the second direction x.

[0077] For example, the line repetition units 10 adjacent to each other along the second direction x may share one third signal sub-line 210 ; and the line repetition units 10 adjacent to each other along the first direction y may share one second signal sub-line 120 .

Optionally, the number of the break 112 in the second sub-area 12 and the third sub-area 13 is equal, so that the break 112 in the line repeating unit 10 is evenly distributed in the first direction y and the second direction x, which is conducive to improving the display uniformity of the display panel.

Optionally, the number of breaks 112 in the second sub-area 12 and the third sub-area 13 is equal, which is also conducive to improving display uniformity. For example, one of the second sub-area 12 and the third sub-area 13 includes a break 112 corresponding to the first sub-signal line 110 of the first sub-network structure 101, and the other includes a break 112 corresponding to the first sub-signal line 110 of the second sub-network structure 102.

That is, the first sub-area 11 includes the break 112 corresponding to the first sub-signal line 110 of the first sub-mesh structure 101 and the break 112 corresponding to the first sub-signal line 110 of the second sub-mesh structure 102 .Correspondingly, the fourth sub-area 14 includes a break 112 corresponding to the first sub-signal line 110 of the first sub-mesh structure 101 and a break 112 corresponding to the first sub-signal line 110 of the second sub-mesh structure 102 .

[0112] Fig.12 is a schematic diagram of a top view of another display panel provided by an embodiment of the present invention, wherein: Fig.12 The figure schematically shows four conductive layers in the display panel, the four conductive layers include an active layer Psi and three metal layers, the three metal layers are respectively referred to as a first metal layer M1, a second metal layer M2 and a third metal layer M3. Optionally, the active layer Psi, the first metal layer M1, the second metal layer M2 and the third metal layer M3 are stacked in sequence on the substrate in a direction away from the substrate, and the first metal layer M1 is located on the side of the active layer Psi away from the substrate. Fig.13 yes Fig.12 Schematic diagram of the top view of the active layer, Fig.14 yes Fig.12 A schematic diagram of the top view of the active layer and the first metal layer, Fig.15 yes Fig.12 A schematic diagram of the structure of the active layer, the first metal layer and the second metal layer, Fig.16 yes Fig.12 Schematic diagram of the structure of the second metal layer and the third metal layer, Fig.17 yes Fig.12 Schematic diagram of the structure of the third metal layer, refer to Figure 12-Figure 17 Optionally, the first sub-signal line 110 of the first sub-network structure 101 is at least partially located between two adjacent columns of pixel circuits, and the first sub-signal line 110 of the first sub-network structure 101 is electrically connected to the first initialization modules 330 in the pixel circuits 300 on both sides. The first sub-signal line 110 of the first sub-network structure 101 extends along the first direction y as a whole, and the first direction is parallel to the column direction of the pixel circuits.

[0113] Specifically, by setting the first sub-signal line 110 of the first sub-mesh structure 101 to be at least partially located between two adjacent columns of pixel circuits 300, the first sub-signal line 110 of the first sub-mesh structure 101 can be connected to the first initialization modules 330 in the two columns of pixel circuits 300 on both sides, and thus there is no need to set a first sub-signal line 110 of the first sub-mesh structure 101 for each column of pixel circuits 300, which can reduce the wiring density of the first sub-signal line 110 in the first sub-mesh structure 101. Since the first sub-signal line 110 of the first mesh structure 100 and the third sub-signal line 210 and the connecting portion 220 of the second mesh structure 200 are all located in the same conductive layer, the reduction in the wiring density of the first sub-signal line 110 in the first sub-mesh structure 101 can provide more wiring space for the third sub-signal line 210, thereby reducing the wiring difficulty.

[0115] Optionally, one second sub-signal line 120 of the first sub-mesh structure 101 and one second sub-signal line 120 of the second sub-mesh structure 102 are correspondingly arranged for every two rows of pixel circuits. The second sub-signal lines 120 of the first sub-mesh structure 101 and the second sub-signal lines 120 of the second sub-mesh structure 102 are arranged in alternate rows, respectively. The alternate row arrangement here may include that the second sub-signal lines 120 of the first sub-mesh structure 101 correspond to the odd-numbered rows of pixel circuits (for example, the second sub-signal lines 120 of the first sub-mesh structure 101 pass through the odd-numbered rows of pixel circuits), and the second sub-signal lines 120 of the second sub-mesh structure 101 correspond to the even-numbered rows of pixel circuits (for example, the second sub-signal lines 120 of the second sub-mesh structure 101 pass through the even-numbered rows of pixel circuits); or the second sub-signal lines 120 of the first sub-mesh structure 101 correspond to the even-numbered rows of pixel circuits (for example, the second sub-signal lines 120 of the first sub-mesh structure 101 pass through the even-numbered rows of pixel circuits), and the second sub-signal lines 120 of the second sub-mesh structure 101 correspond to the odd-numbered rows of pixel circuits (for example, the second sub-signal lines 120 of the second sub-mesh structure 101 pass through the odd-numbered rows of pixel circuits).

[0116] Specifically, the space between the first scan line Scan1 and the second sub-signal line 120 of the second sub-mesh structure 102 adjacent to the first scan line Scan1 is relatively large, and the space between the first scan line Scan1 and the second sub-signal line 120 of the first sub-mesh structure 101 adjacent to the first scan line Scan1 is relatively large. The position setting method of the above-mentioned connection points can facilitate the connection between the first initialization module 330 and the first sub-signal line 110 in the first sub-mesh structure 101, and avoid short circuit.

[0117] refer to Figure 4 and Figure 5 , Figure 12-Figure 17 Optionally, the pixel circuit further includes part or all of a data writing module, a compensation module, a storage module, a first light-emitting control module and a second light-emitting control module, wherein the driving module 310 includes a driving transistor T1, the data writing module includes a second transistor T2, the compensation module includes a third transistor T3, the first initialization module 330 includes a fourth transistor T4, the first light-emitting control module includes a fifth transistor T5, the second light-emitting control module includes a sixth transistor T6, and the storage module includes a storage capacitor Cst.

As Figure 4As shown, the control end of the data writing module is electrically connected to the second scan line Scan2, the first end of the data writing module is electrically connected to the data line (for example, the data line DL1 or DL2), and the second end of the data writing module is electrically connected to the first end of the driving module 310. The control end of the compensation module is electrically connected to the second scan line Scan2, the first end of the compensation module is electrically connected to the second end of the driving module 310, and the second end of the compensation module is electrically connected to the control end of the driving module 310. The first light-emitting control module is connected between the power line VDD and the first end of the driving module 310, the second light-emitting control module is connected between the second end of the driving module 310 and the first pole (for example, the anode) of the light-emitting device 320, and the control end of the first light-emitting control module and the control end of the second light-emitting control module are both electrically connected to the light-emitting control signal line EM. The control end of the first initialization module 330 is electrically connected to the first scan line Scan1, the first end of the first initialization module 330 is electrically connected to the initialization signal line Vref, and the second end of the first initialization module 330 is electrically connected to the control end of the driving module 310 or the second end of the driving module 310. The control end of the second initialization module 340 is electrically connected to the first scan line Scan1 or the third scan line, the first end of the second initialization module 340 is electrically connected to the initialization signal line Vref, and the second end of the second initialization module 340 is electrically connected to the first electrode of the light emitting device 320. Figure 5 As shown, when the pixel circuit includes a third initialization module 350 (the third initialization module 350 includes an eighth transistor T8), the control end of the third initialization module 350 is electrically connected to or from the third scan line, the first end of the third initialization module 350 is electrically connected to the initialization signal line Vref, and the second end of the third initialization module 350 is electrically connected to the first end or the second end of the driving module 310. It should be noted that when the first mesh structure includes a plurality of sub-mesh structures, the first initialization module 330, the second initialization module 340, and the third initialization module 350 can be connected to different sub-mesh structures. The gate of the second transistor T2 and the gate of the third transistor T3 are electrically connected to the second scan line Scan2, respectively, and the gate of the fifth transistor T5 and the gate of the sixth transistor T6 are electrically connected to the light emitting control signal line EM, respectively.

[0118] Optionally, the first sub-signal line 110 of the second sub-network structure 102 is at least partially located between two adjacent columns of pixel circuits 300, and the first sub-signal line 110 of the second sub-network structure 102 is electrically connected to the second initialization modules 340 in the pixel circuits 300 on both sides, respectively; the first scan line Scan1 is electrically connected to the control end of the second initialization module 340. The first sub-signal line 110 of the second sub-network structure 102 extends as a whole along the first direction y.

[0119] Specifically, by setting the first sub-signal line 110 of the second sub-mesh structure 102 to be at least partially located between two adjacent columns of pixel circuits 300, the first sub-signal line 110 of the second sub-mesh structure 102 can be connected to the second initialization modules 340 in the two columns of pixel circuits 300 on both sides, and thus there is no need to set a first sub-signal line 110 of the second sub-mesh structure 102 for each column of pixel circuits 300, which can reduce the wiring density of the first sub-signal line 110 in the second sub-mesh structure 102. Since the first sub-signal line 110 of the first mesh structure 100 and the third sub-signal line 210 and the connecting portion 220 of the second mesh structure 200 are all located in the same conductive layer, the reduction in the wiring density of the first sub-signal line 110 in the second sub-mesh structure 102 can provide more wiring space for the third sub-signal line 210, thereby reducing the wiring difficulty.

[0120] Optionally, the connection points of the first sub-signal line 110 of the second sub-mesh structure 102 and the first initialization modules 330 in the pixel circuits 300 on both sides (respectively Figure 8 The third connection point Q1 and the fourth connection point Q2) are both located on the side of the first scan line Scan1 away from the second sub-signal line 120 of the second sub-mesh structure 102 adjacent to the first scan line Scan1, or the side of the first scan line Scan1 away from the second sub-signal line 120 of the first sub-mesh structure 101 adjacent to the first scan line Scan1.

[0121] Specifically, the space on the side of the first scan line Scan1 away from the second sub-signal line 120 of the second sub-network structure 102 adjacent to the first scan line Scan1 is relatively large, and the space on the side of the first scan line Scan1 away from the second sub-signal line 120 of the first sub-network structure 101 adjacent to the first scan line Scan1 is relatively large. The above-mentioned connection point position setting method can facilitate the connection between the second initialization module 340 and the first sub-signal line 110 in the second sub-network structure 102 to avoid short circuit. Optionally, the first initialization modules 330 in two adjacent pixel circuits in the same row are arranged in mirror symmetry; the second initialization modules 340 in two adjacent pixel circuits in the same row are arranged in mirror symmetry; the second direction x is parallel to the row direction of the pixel circuit.

[0122] Optionally, in two columns of pixel circuits 300 adjacent to the first sub-signal line 110 of the first sub-network structure 101, the distance from the first initialization module 330 to the first sub-signal line 110 of the first sub-network structure 101 between the two adjacent columns of pixel circuits 300 is smaller than the distance from the second initialization module 340 to the first sub-signal line 110 of the first sub-network structure 101 between the two adjacent columns of pixel circuits 300. In this way, the connection between the first initialization module 330 and the first sub-signal line 110 of the first sub-network structure 101 is facilitated.

[0123] Optionally, in two columns of pixel circuits 300 adjacent to the first sub-signal line 110 of the second sub-network structure 102, the distance from the second initialization module 340 to the first sub-signal line 110 of the second sub-network structure 102 between the two adjacent columns of pixel circuits 300 is smaller than the distance from the first initialization module 330 to the first sub-signal line 110 of the second sub-network structure 102 between the two adjacent columns of pixel circuits 300. In this way, the connection between the second initialization module 340 and the first sub-signal line 110 in the second sub-network structure 102 is facilitated.

[0124] Continue to refer Figure 12-Figure 17 Optionally, the second mesh structure 200 further includes a plurality of fourth sub-signal lines 230 , the fourth sub-signal lines 230 extending along the second direction x, the fourth sub-signal lines 230 and the third sub-signal lines 210 being located in different conductive layers, and the fourth sub-signal lines 230 being electrically connected to at least one third sub-signal line 210 .

[0125] Specifically, the third sub-signal line 210 and the first sub-signal line 110 of the first mesh structure 100 are located in the same conductive layer, the third sub-signal line 210 and the first sub-signal line 110 transmit different signals, and the fourth sub-signal line 230 of the second mesh structure 200 and the third sub-signal line 210 are in different layers, so that the fourth sub-signal line 230 and the first sub-signal line 110 are connected in a circuit. By setting the second mesh structure 200 to also include the fourth sub-signal line 230, the resistance of the second mesh structure 200 can be further reduced, so that the display uniformity of the display panel can be further improved.

[0126] In some optional embodiments of the present invention, the fourth signal sub-line 230 and the second signal sub-line 120 are located in the same conductive layer. In this way, the number of conductive layers in the display panel can be reduced, which is conducive to simplifying the display panel manufacturing process and reducing the thickness of the display panel.

[0127] Optionally, the first sub-signal line 110, the third sub-signal line 210 and the connecting portion 220 are located in the first conductive layer, and the fourth sub-signal line 230 and the second sub-signal line 120 are located in the second conductive layer. The resistivity of the conductive material of the first conductive layer is less than the resistivity of the conductive material of the second conductive layer, and / or, along the direction perpendicular to the substrate, the thickness of the first conductive layer is greater than the thickness of the second conductive layer. In this embodiment, by forming the second mesh structure 200 in the first conductive layer, the cross-sectional area of ​​the second mesh structure 200 in the first direction y and the cross-sectional area in the second direction x in the first conductive layer are both large, and because the resistivity of the first conductive layer is small and / or the thickness is large, the second mesh structure 200 can have a smaller resistance, which is beneficial to further reduce the transmission voltage drop of the signal in the second mesh structure 200 in the first direction y and the second direction x, thereby further improving the display uniformity.

[0128] Optionally, the second conductive layer is located on a side of the first conductive layer away from the substrate. The first conductive layer may be the second metal layer M2, and the second conductive layer may be the third metal layer M3.

[0129] Fig.18 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, wherein Fig.18 Schematically shows two conductive layers, namely a third metal layer M3 and a fourth metal layer M4. The fourth metal layer M4 is located on a side of the third metal layer M3 away from the second metal layer. Fig.19 yes Fig.18 A partial structural diagram of the second metal layer, the third metal layer and the fourth metal layer, Fig. 20 is a cross-sectional view of a display panel provided by an embodiment of the present invention, and the cross-sectional view of the display panel may correspond to Fig.19 Cut along BB', refer to Figure 17-Figure 20 Optionally, the display panel further includes a data line, the data line and the first sub-signal line 110 and the third sub-signal line 210 are located in different conductive layers; the data line extends along the first direction y; the display panel further includes a plurality of pixel circuits 300 arranged in an array, the data line is electrically connected to the pixel circuit 300; the pixel circuit 300 includes a driving transistor, the driving transistor includes a gate, and the gate is connected to a conductive portion 401; along the second direction x, the third sub-signal line 210 is at least partially located between the conductive portion 401 and the data line. For example, the orthographic projection of at least part of the third sub-signal line 210 on the substrate is located between the orthographic projection of the conductive portion 401 on the substrate and the orthographic projection of the data line on the substrate.

[0130] Specifically, the extension direction of the data line is the same as that of the first sub-signal line 110 and the third sub-signal line 210, and the data line and the first sub-signal line 110 and the third sub-signal line 210 are arranged in different conductive layers, so as to facilitate the connection between the data line and the pixel circuit 300. The gate of the driving transistor in the pixel circuit 300 is connected to a conductive part 401 (for example, electrically connected to the second end of the first initialization module and / or the second end of the compensation module), and the conductive part 401 has the same potential as the gate. Along the second direction x, the third sub-signal line 210 is at least partially located between the conductive part 401 and the data line, so that the interference of the potential jump on the data line to the conductive part 401 can be shielded by the third sub-signal line 210 in the second direction x, thereby improving the stability of the gate potential of the driving transistor, which is beneficial to improving the flickering phenomenon of the display panel and improving the display effect. Optionally, the conductive part 401 and the third sub-signal line 210 are located in the same conductive layer.

[0131] Continue to refer Fig.17 Optionally, the data line includes a first data line DL1 and a second data line DL2, and each column of pixel circuits 300 is correspondingly connected to a first data line DL1 and a second data line DL2, and the first data line DL1 and the second data line DL2 electrically connected to the same column of pixel circuits 300 are located on both sides of the conductive portion 401; along the second direction x, the third sub-signal line 210 is at least partially located between the conductive portion 401 and the second data line DL2. For example, the orthographic projection of at least part of the third sub-signal line 210 on the substrate is located between the orthographic projection of the conductive portion 401 on the substrate and the orthographic projection of the second data line DL2 on the substrate. The first direction y is parallel to the column direction of the pixel circuit. In this way, the number of pixel circuits 300 connected to the same data line can be reduced, reducing the load of the data line, which is conducive to further improving the display effect.

[0132] Optionally, the first data line DL1 is electrically connected to the pixel circuits 300 located in odd rows, and the second data line DL2 is electrically connected to the pixel circuits 300 located in even rows. The second direction x is parallel to the row direction of the pixel circuits.

[0133] Optionally, the display panel further includes a plurality of first shielding portions 402, the third sub-signal line 210 is electrically connected to the first shielding portion 402, and the potential on the third sub-signal line 210 is a fixed potential; the orthographic projection of the first shielding portion 402 on the substrate is at least partially located between the orthographic projection of the first data line DL1 on the substrate and the orthographic projection of the conductive portion 401 on the substrate, see Fig.19 .like Fig. 20 As shown, the first shielding portion 402 is also partially located between the second data line DL2 and the active layer Psi (which may be the active layer of the third transistor of the compensation module), which can shield the influence of the potential jump on the second data line DL2 on the potential on the active layer Psi.

[0134] Since the potential on the third sub-signal line 210 is a fixed point or a power supply voltage, and the first shielding portion 402 is electrically connected to the third sub-signal line 210, the potential of the first shielding portion 402 is also a fixed potential. The orthographic projection of the first shielding portion 402 on the substrate is at least partially located between the orthographic projection of the first data line DL1 on the substrate and the orthographic projection of the conductive portion 401 on the substrate, so that the first shielding portion 402 can shield the interference of the potential jump on the first data line DL1 on the second direction x to the conductive portion 401, further improve the stability of the gate potential of the driving transistor, improve the flickering phenomenon of the display panel, and improve the display effect. Optionally, the first shielding portion 402 and the second sub-signal line 120 are located in the same conductive layer. Optionally, the orthographic projection of the first shielding portion 402 on the substrate at least partially overlaps with the orthographic projection of the second data line DL2 on the substrate to shield the interference of the potential jump on the first data line DL1 on the conductive portion 401.

[0135] Continue to refer Fig.17 Optionally, the display panel also includes a shielding signal line 410, and the potential on the shielding signal line 410 is a fixed potential or a power supply voltage; the shielding signal line 410 extends along the first direction y, and the conductive layer where the shielding signal line 410 is located and the conductive layer where the data line is located are both located on the side of the conductive layer where the gate is located and the conductive layer where the conductive part 401 is located away from the substrate; the shielding signal line 410 includes a second shielding part 411, and the positive projection of the second shielding part 411 on the substrate covers the positive projection of the conductive part 401 on the substrate. In this way, when the potential on the data line jumps, the potential on the shielding signal line 410 will not jump, and then the interference of the potential jump of the shielding data line on the potential on the conductive part 401 in the thickness direction of the display panel can further ensure the stability of the gate potential of the driving transistor, and further improve the display effect of the display panel.

[0136] Optionally, the shielding signal line 410 and the data line are located in the same conductive layer, and the shielding signal line 410 is located between the adjacent first data line DL1 and the second data line DL2. In this way, on the one hand, the number of conductive layers in the display panel can be reduced, and on the other hand, the shielding signal line 410 can better interfere with the potential jump on the first data line DL1 and the potential jump on the second data line DL2 on the potential of the conductive part 401, thereby ensuring the stability of the gate point of the driving transistor and further improving the display effect.

[0137] In an optional embodiment of the present invention, the shielding signal line 410 is electrically connected to the second mesh structure 200 .

[0138] In another optional embodiment of the present invention, the shielding signal line 410 is electrically connected to the first mesh structure 100, for example, electrically connected to a sub-mesh structure of the first mesh structure 100. Exemplarily, the shielding signal line 410 is electrically connected to the first sub-mesh structure 101, or the shielding signal line 410 is electrically connected to the second sub-mesh structure 102.

[0139] In other optional embodiments of the present invention, the shielding signal line 410 is electrically connected to the second pole of the light-emitting device in the display panel. That is, the shielding signal line 410 may be at least partially located in the display area, so that, compared with the display panel structure in which the shielding signal line 410 is only provided in the non-display area and connected to the second pole of the light-emitting device, the difference in signals received by the second poles of the light-emitting devices at different positions may be smaller, which is conducive to further improving the display uniformity.

[0140] An embodiment of the present invention further provides a display device, Fig.21 is a schematic diagram of a display device provided by an embodiment of the present invention, with reference to Fig.21 Optionally, the display device includes the display panel of any of the above embodiments of the present invention.

[0141] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0142] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
