For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0102] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0103] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0104] This application provides a display panel and a display device. The embodiments of the display panel and the display device will be described below with reference to the accompanying drawings.

[0105] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0106] Please refer to Figures 1 to 4 together. Figure 1 is a partial top view of a display panel provided in an embodiment of this application; Figure 2 is a partial cross-sectional view of Figure 1; Figure 3 is a partial top view of a display panel in another embodiment; and Figure 4 is a partial cross-sectional view of Figure 3.

[0107] As shown in Figures 1 to 4, a first aspect embodiment of this application provides a display panel 10, which includes: a substrate 100; and a touch layer 200 located on one side of the substrate 100. The touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220 sequentially stacked thereon, with the second conductive layer 220 located on the side of the first conductive layer 210 facing away from the substrate 100. The touch layer 200 includes a touch structure 300, which includes a first touch structure 310 located on the first conductive layer 210 and a second conductive layer 220. The second touch structure 320 includes a first segment 311 of the first touch structure 310 and a second segment 321 of the second touch structure 320. Both the first segment 311 and the second segment 321 extend along the first direction X. The orthographic projection of the first segment 311 on the substrate 100 and the orthographic projection of the second segment 321 on the substrate 100 overlap at least partially. The orthographic projections of the first segment 311 on at least one side of the second direction Y and the second segment 321 on the same side of the second direction Y are offset on the substrate 100. The first direction X and the second direction Y intersect.

[0108] According to an embodiment of this application, the display panel 10 includes a substrate 100 and a touch layer 200. The touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220. The touch structure 300 of the touch layer 200 includes a first touch structure 310 located on the first conductive layer 210 and a second touch structure 320 located on the second conductive layer 220. The first touch structure 310 and the second touch structure 320 are used to realize the touch function of the display panel 10. For example, the first touch structure 310 and the second touch structure 320 can both be touch connection lines to realize the transmission of touch signals. The first segment 311 of the first touch structure 310 and the second segment 321 of the second touch structure 320 overlap, and the orthographic projections of at least one edge of the first segment 311 on the second direction Y and the edge of the second segment 321 on the same side on the substrate 100 are misaligned. This can improve the problem of the first segment 311 and the second segment 321 overlapping on the substrate 100 in the second direction Y, which would otherwise cause stress concentration in the insulating layer 230 between the first segment 311 and the second segment 321, leading to the problem of film breakage of the insulating layer 230. This can improve the problem of black spots caused by screen cracks or encapsulation failures due to the external folding and arching of the display panel 10, and improve the performance of the display panel 10.

[0109] Optionally, the display panel 10 is a foldable display panel 10, which has at least an inward-folded state, in which the display surfaces of the display panel 10 are close to each other. When the display panel 10 is dropped in the inward-folded state, the bending area of ​​the display panel 10 is subjected to force, resulting in outward folding and arching, which can easily lead to screen cracks or black spots caused by encapsulation failure. Therefore, the embodiments of this application can improve the problem of black spots caused by screen cracks or encapsulation failure due to outward folding and arching of the display panel 10, and improve the performance of the display panel 10.

[0110] There are many other ways to arrange the substrate 100. For example, the substrate 100 may include a substrate and an array substrate disposed on the substrate. Alternatively, the substrate 100 may be the substrate itself. Or the substrate 100 may include a buffer layer and a support plate on the side facing away from the substrate.

[0111] Please refer to Figures 1 and 5, where Figure 5 is a partial cross-sectional view of the display panel in another embodiment.

[0112] As shown in Figures 1 and 5, in some optional embodiments, the orthographic projection of the first segment 311 on the substrate 100 has a first edge 311a and a second edge 311b disposed opposite to each other in the second direction Y, and the orthographic projection of the second segment 321 on the substrate 100 has a third edge 321a and a fourth edge 321b disposed opposite to each other in the second direction Y. The first edge 311a and the third edge 321a are located on the same side, the second edge 311b and the fourth edge 321b are located on the same side, the first edge 311a and the third edge 321a are offset, and / or the second edge 311b and the fourth edge 321b are offset.

[0113] The first edge 311a and the third edge 321a are misaligned; or the second edge 311b and the fourth edge 321b are misaligned; or the first edge 311a and the third edge 321a are misaligned, and the second edge 311b and the fourth edge 321b are misaligned.

[0114] The misalignment of the first edge 311a and the third edge 321a can refer to the misalignment of the orthographic projections of the first edge 311a and the third edge 321a on the substrate 100; the misalignment of the second edge 311b and the fourth edge 321b can refer to the misalignment of the orthographic projections of the second edge 311b and the fourth edge 321b on the substrate 100.

[0115] In these optional embodiments, the first edge 311a and the third edge 321a are misaligned, which improves the overlap of the orthographic projections of the first edge 311a and the third edge 321a on the substrate 100, thus preventing stress concentration in the insulating layer 230 between the first segment 311 and the second segment 321 on the side closer to the first edge 311a and the third edge 321a. Similarly, the second edge 311b and the fourth edge 321b are misaligned, which improves the overlap of the orthographic projections of the second edge 311b and the fourth edge 321b on the substrate 100, thus preventing stress concentration in the insulating layer 230 between the first segment 311 and the second segment 321 on the side closer to the second edge 311b and the fourth edge 321b. The first edge 311a and the third edge 321a are misaligned, and the second edge 311b and the fourth edge 321b are also misaligned. This can improve the problem of stress concentration on both sides of the insulating layer 230 between the first segment 311 and the second segment 321 in the second direction Y. This further reduces the risk of stress concentration in the insulating layer 230, thereby improving the problem of black spots caused by screen cracks or encapsulation failures due to the external folding and arching of the display panel 10, and improving the performance of the display panel 10.

[0116] Optionally, the first edge 311a and the second edge 311b are parallel, and / or the third edge 321a and the fourth edge 321b are parallel, and / or the third edge 321a and the first edge 311a are parallel, and / or the fourth edge 321b and the second edge 311b are parallel.

[0117] Optionally, the first edge 311a, the second edge 311b, the third edge 321a, and the fourth edge 321b are all parallel.

[0118] In some alternative embodiments, the first edge 311a and / or the second edge 311b is located between the third edge 321a and the fourth edge 321b; or, the third edge 321a and / or the fourth edge 321b is located between the first edge 311a and the second edge 311b.

[0119] The first edge 311a and / or the second edge 311b being located between the third edge 321a and the fourth edge 321b means that the orthographic projection of the first edge 311a and / or the second edge 311b on the substrate 100 is located between the orthographic projections of the third edge 321a and the fourth edge 321b on the substrate 100; the third edge 321a and / or the fourth edge 321b being located between the first edge 311a and the second edge 311b means that the orthographic projection of the third edge 321a and / or the fourth edge 321b on the substrate 100 is located between the orthographic projections of the first edge 311a and the second edge 311b on the substrate 100.

[0120] In these optional embodiments, the first edge 311a and the second edge 311b can be arranged in various ways. For example, the first edge 311a is located between the third edge 321a and the fourth edge 321b; or, the second edge 311b is located between the third edge 321a and the fourth edge 321b; or, both the first edge 311a and the second edge 311b are located between the third edge 321a and the fourth edge 321b. The third edge 321a and the fourth edge 321b can also be arranged in various ways. For example, the third edge 321a is located between the first edge 311a and the second edge 311b; or, the fourth edge 321b is located between the first edge 311a and the second edge 311b; or, both the third edge 321a and the fourth edge 321b are located between the first edge 311a and the second edge 311b. That is, the first edge 311a and the third edge 321a are misaligned, and the second edge 311b and the fourth edge 321b are misaligned. This can improve the problem of the first edge 311a and the third edge 321a, the second edge 311b and the fourth edge 321b being coincident on the substrate 100, which makes it easy for stress concentration to occur on both sides of the insulating layer 230 between the first segment 311 and the second segment 321 in the second direction Y. This further reduces the risk of stress concentration in the insulating layer 230, thereby improving the problem of black spots caused by screen cracks or encapsulation failures due to the external folding and arching of the display panel 10, and improving the performance of the display panel 10.

[0121] As shown in FIG2, in some optional embodiments, the insulating layer 230 includes a first flat portion 231, a slope 232 and a second flat portion 233 connected in sequence. The second flat portion 233 is located on the side of the first flat portion 231 away from the substrate 100. The slope 232 and the first flat portion 231 have an intersecting position. The orthographic projection of the intersecting position on the substrate 100 is located within the orthographic projection of the second segment 321 on the substrate 100.

[0122] In these alternative embodiments, when the intersection of the insulating layer 230 is covered by the second segment 321, and the orthographic projection of the edge of the first segment 311 on one side in the second direction Y and the edge of the second segment 321 on the same side on the substrate 100 is misaligned, the stress at the intersection where stress concentration is likely to occur is reduced, thereby improving the problem of the insulating layer 230 film layer cracking caused by stress concentration at the intersection.

[0123] In some alternative embodiments, the orthographic projections of the first flat portion 231 and the second flat portion 233 on the substrate 100 at least partially overlap with the orthographic projection of the second segment 321 on the substrate 100.

[0124] Optionally, the orthographic projection of the second flat portion 233 on the substrate 100 at least partially overlaps with the orthographic projection of the first segment 311 on the substrate 100.

[0125] Optionally, the orthographic projection of the slope 232 and at least part of the second flat portion 233 on the substrate 100 lies within the orthographic projection of the second segment 321 on the substrate 100.

[0126] Optionally, at least a portion of the first flat portion 231 may have its orthographic projection on the substrate 100 located within the orthographic projection of the second segment 321 on the substrate 100.

[0127] In some alternative embodiments, the orthographic projection of the intersecting position on the substrate 100 is outside the orthographic projection of the first segment 311 on the substrate 100.

[0128] Optionally, the material of the insulating layer 230 may include inorganic materials.

[0129] Optionally, the display panel 10 may also include an adhesive layer located on the side of the second conductive layer 220 opposite to the substrate 100.

[0130] Optionally, the adhesive layer material includes photoresist (OC adhesive).

[0131] As shown in Figure 5, in some optional embodiments, the distance d1 between the first edge 311a and the third edge 321a is greater than or equal to 0.5 μm. For example, the distance between the first edge 311a and the third edge 321a is 0.5 μm, 1 μm, 1.25 μm, 5 μm, etc.

[0132] In these optional embodiments, the distance between the first edge 311a and the third edge 321a is greater than or equal to 0.5 μm, which can improve the problem that the stress concentration location of the insulating layer 230 is not significantly reduced due to the small distance between the first edge 311a and the third edge 321a, such as the intersection location near the first edge 311a and the third edge 321a, and the insulating layer 230 is prone to film breakage.

[0133] In some optional embodiments, the distance d2 between the second edge 311b and the fourth edge 321b is greater than or equal to 0.5 μm. For example, the distance between the second edge 311b and the fourth edge 321b is 0.5 μm, 1 μm, 1.25 μm, 5 μm, etc.

[0134] In these optional embodiments, the distance between the second edge 311b and the fourth edge 321b is greater than or equal to 0.5 μm, which can improve the problem that the stress concentration location of the insulating layer 230 caused by the small distance between the second edge 311b and the fourth edge 321b is not significantly reduced, and the insulating layer 230 is prone to film breakage.

[0135] Optionally, the distance between the first edge 311a and the third edge 321a is equal to the distance between the second edge 311b and the fourth edge 321b, so that the stress distribution of the insulating layer 230 on the side near the first edge 311a is similar to the stress distribution on the side near the second edge 311b, thereby improving the uniformity of the stress distribution of the insulating layer 230 and improving the problem of stress concentration in the insulating layer 230 leading to film breakage.

[0136] In some optional embodiments, the distance d1 between the first edge 311a and the third edge 321a is greater than or equal to 1 μm. For example, the distance between the first edge 311a and the third edge 321a is 1 μm, 1.25 μm, 2 μm, 5 μm, etc.

[0137] In these optional embodiments, the distance between the first edge 311a and the third edge 321a is greater than or equal to 1 μm, which can improve the problem that the stress concentration location of the insulating layer 230 is not significantly reduced due to the small distance between the first edge 311a and the third edge 321a, and the insulating layer 230 is prone to film breakage.

[0138] In some optional embodiments, the distance d2 between the second edge 311b and the fourth edge 321b is greater than or equal to 1 μm. For example, the distance between the second edge 311b and the fourth edge 321b is 1 μm, 1.25 μm, 2 μm, 5 μm, etc.

[0139] In these optional embodiments, the distance between the second edge 311b and the fourth edge 321b is greater than or equal to 1 μm, which can improve the problem that the stress concentration location of the insulating layer 230 is not significantly reduced due to the small distance between the second edge 311b and the fourth edge 321b, and the insulating layer 230 is prone to film breakage.

[0140] Specifically, when the distance between the first edge 311a and the third edge 321a is 1 μm, and the distance between the second edge 311b and the fourth edge 321b is 1 μm, in the simulation analysis, compared with the scheme where the orthographic projections of the first edge 311a and the third edge 321a on the substrate 100 coincide, and the orthographic projections of the second edge 311b and the fourth edge 321b on the substrate 100 coincide, the stress on the insulating layer 230 at the intersection position is reduced by 9%.

[0141] Please refer to Figure 6, which is a partial top view of the display panel in another embodiment.

[0142] As shown in Figure 6, in some optional embodiments, the orthographic projection of the second segment 321 on the substrate 100 has a fifth edge 321c and a sixth edge 321d disposed opposite to each other in the first direction X. A first chamfered segment 321e is provided between the fifth edge 321c and the third edge 321a. The included angle between any two adjacent segments of the third edge 321a, the first chamfered segment 321e and the fifth edge 321c that are connected in sequence is greater than 90°.

[0143] In these optional embodiments, one side of the second segment 321 is configured as three segments: the third edge 321a, the first chamfered segment 321e, and the fifth edge 321c, with the included angle between any two adjacent segments being greater than 90°. That is, the included angle between the third edge 321a and the first chamfered segment 321e is greater than 90°, and the included angle between the first chamfered segment 321e and the fifth edge 321c is greater than 90°. This makes the transition between the third edge 321a and the fifth edge 321c smooth, which can reduce the abrupt change in stiffness of the second segment 321 and thus improve the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0144] Optionally, the length of the fifth edge 321c is less than the length of the third edge 321a.

[0145] Optionally, the angle between any two of the third edge 321a, the first chamfered segment 321e, and the fifth edge 321c is greater than 90°, the angle between the third edge 321a and the first chamfered segment 321e is greater than 90°, and the angle between the first chamfered segment 321e and the fifth edge 321c is greater than 90°, and the angle between the third edge 321a and the fifth edge 321c is greater than 90°, so that the transition between the third edge 321a and the fifth edge 321c is smoother, which can further reduce the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0146] In some alternative embodiments, a second chamfered segment 321f is provided between the sixth edge 321d and the fourth edge 321b, and the included angle between any two adjacent of the fourth edge 321b, the second chamfered segment 321f and the sixth edge 321d is greater than 90°.

[0147] In these optional embodiments, the other side of the second segment 321 is configured as three segments: the fourth edge 321b, the second chamfered segment 321f, and the sixth edge 321d, with the included angle between any two adjacent segments being greater than 90°. That is, the included angle between the fourth edge 321b and the second chamfered segment 321f is greater than 90°, and the included angle between the second chamfered segment 321f and the sixth edge 321d is greater than 90°. This makes the transition between the fourth edge 321b and the sixth edge 321d smooth, which can reduce the abrupt change in stiffness of the second segment 321 and thus improve the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0148] Optionally, the length of the sixth edge 321d is less than the length of the fourth edge 321b.

[0149] Optionally, the angle between any two of the fourth edge 321b, the second chamfered segment 321f, and the sixth edge 321d is greater than 90°, the angle between the fourth edge 321b and the second chamfered segment 321f is greater than 90°, and the angle between the second chamfered segment 321f and the sixth edge 321d is greater than 90°, and the angle between the fourth edge 321b and the sixth edge 321d is greater than 90°. This makes the transition between the fourth edge 321b and the sixth edge 321d smoother, which can further reduce the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0150] Optionally, the orthographic projection of the first chamfered segment 321e on the substrate 100 is located within the orthographic projection of the first touch structure 310 on the substrate 100, thereby reducing the abrupt decrease in stiffness at the overlap position of the first touch structure 310 and the second segment 321.

[0151] Optionally, the orthographic projection of the second chamfered segment 321f on the substrate 100 is located within the orthographic projection of the first touch structure 310 on the substrate 100, thereby reducing the abrupt decrease in stiffness at the overlap position of the first touch structure 310 and the second segment 321.

[0152] Please refer to Figure 7, which is a partial top view of the display panel in another embodiment.

[0153] As shown in Figure 7, in some alternative embodiments, the third edge 321a includes a curve.

[0154] In these alternative embodiments, the two ends of the second segment 321 in the second touch structure 320 are connected by a curve, making the transition of the second touch structure 320 at the third edge 321a more gradual. This can further reduce the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0155] In some optional embodiments, the radius of curvature of the third edge 321a is greater than or equal to 5 μm. For example, the radius of curvature of the third edge 321a is 5 μm, 6 μm, 8 μm, 10 μm, etc. The radius of curvature of the third edge 321a being greater than or equal to 5 μm means that the radius of curvature at each position of the third edge 321a is greater than or equal to 5 μm.

[0156] In these optional embodiments, the radius of curvature of the third edge 321a is greater than or equal to 5 μm, making the transition of the second touch structure 320 at the third edge 321a smoother. This further reduces the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration leading to breakage of the second segment 321. It also improves the problem of an excessively small radius of curvature of the third edge 321a, resulting in excessive bending, a large abrupt change in stiffness, and stress concentration and breakage of the insulating layer 230.

[0157] In some alternative embodiments, the fourth edge 321b includes a curve.

[0158] In these alternative embodiments, the two ends of the second segment 321 in the second touch structure 320 are connected by a curve, making the transition of the second touch structure 320 at the fourth edge 321b position smoother. This can further reduce the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration in the insulating layer 230 leading to the breakage of the second segment 321.

[0159] In some optional embodiments, the radius of curvature of the fourth edge 321b is greater than or equal to 5 μm. For example, the radius of curvature of the fourth edge 321b is 5 μm, 6 μm, 8 μm, 10 μm, etc. The radius of curvature of the fourth edge 321b being greater than or equal to 5 μm means that the radius of curvature at each position of the fourth edge 321b is greater than or equal to 5 μm.

[0160] In these optional embodiments, the radius of curvature of the fourth edge 321b is greater than or equal to 5 μm, making the transition of the second touch structure 320 at the fourth edge 321b position smoother. This further reduces the abrupt change in stiffness of the second segment 321, thereby improving the problem of stress concentration in the insulating layer 230 leading to breakage of the second segment 321. It also improves the problem of an excessively small radius of curvature of the fourth edge 321b, resulting in excessive bending and a large abrupt change in stiffness, which makes the insulating layer 230 prone to stress concentration and breakage.

[0161] Please refer to Figure 8, which is a partial top view of the display panel in another embodiment.

[0162] As shown in Figure 8, optionally, the first touch structure 310 further includes a first main body portion 312 located on at least one side of the first segment 311. The orthographic projection of the first main body portion 312 on the substrate 100 has a first side 312a and a second side 312b disposed opposite to each other. The first side 312a is connected to the first edge 311a, and the second side 312b is connected to the second edge 311b. The included angle between the first side 312a and the first edge 311a is greater than 90°; or, the included angle between the second side 312b and the second edge 311b is greater than 90°; or, the included angle between the first side 312a and the first edge 311a is greater than 90°, and the included angle between the second side 312b and the second edge 311b is greater than 90°. The angle between the first side 312a and the first edge 311a is greater than 90°, resulting in a smooth transition between them. This reduces abrupt changes in the stiffness of the first touch structure 310, thereby mitigating the problem of stress concentration in the insulating layer 230 leading to breakage. Similarly, the angle between the second side 312b and the second edge 311b is also greater than 90°, resulting in a smooth transition between them. This reduces abrupt changes in the stiffness of the first touch structure 310, further mitigating the problem of stress concentration in the insulating layer 230 leading to breakage.

[0163] Optionally, the second touch structure 320 further includes a second main body portion 322 located at both ends of the second segment 321. The orthographic projection of the second main body portion 322 on the substrate 100 has a third side 322a and a fourth side 322b disposed opposite to each other. The third side 322a is connected to the third edge 321a, and the fourth side 322b is connected to the fourth edge 321b. The included angle between the third side 322a and the third edge 321a is greater than 90°; or, the included angle between the fourth side 322b and the fourth edge 321b is greater than 90°; or, the included angle between the third side 322a and the third edge 321a is greater than 90°, and the included angle between the fourth side 322b and the fourth edge 321b is greater than 90°. The angle between the third side 322a and the third edge 321a is greater than 90°, resulting in a smooth transition between them. This reduces abrupt changes in the stiffness of the second touch structure 320, thereby mitigating the problem of stress concentration in the insulating layer 230 leading to breakage. Similarly, the angle between the fourth side 322b and the fourth edge 321b is also greater than 90°, resulting in a smooth transition between them. This reduces abrupt changes in the stiffness of the second touch structure 320, further mitigating the problem of stress concentration in the insulating layer 230 leading to breakage.

[0164] In some alternative embodiments, the first side 312a and the third side 322a are vertically arranged, and / or the first side 312a and the fourth side 322b are vertically arranged, and / or the second side 312b and the third side 322a are vertically arranged, and / or the second side 312b and the fourth side 322b are vertically arranged.

[0165] In these alternative embodiments, the edges of the first body portion 312 and the second body portion 322 are perpendicular to each other, which can further reduce the abrupt change in stiffness of the first touch structure 310 and the second touch structure 320, thereby improving the problem of stress concentration leading to fracture in the insulating layer 230.

[0166] Please refer to Figures 1 to 9 together. Figure 9 is a top view of a display panel provided in an embodiment of this application.

[0167] As shown in Figures 1 to 9, optionally, the display panel 10 includes a bending axis 11, and at least a portion of the touch structures 300 have an angle between their extending directions and the bending axis 11. For example, the first touch structure 310 has an angle with the bending axis 11, and / or the second touch structure 320 has an angle with the bending axis 11. That is, at least a portion of the touch structures 300 are not parallel to the bending axis 11, to avoid the problem that paralleling the extending directions of the touch structures 300 with the bending axis 11 would increase the abrupt change in stiffness of the display panel 10 during the anti-arching process, forming stress concentration points and causing film layer breakage.

[0168] Optionally, all the extension directions of the touch structures 300 have an angle with the bending axis 11, which can further avoid the problem of the extension direction of the touch structures 300 being parallel to the bending axis 11, which would increase the sudden change in stiffness of the display panel 10 during the anti-arching process, form stress concentration points, and thus cause the film layer to break.

[0169] Optionally, the included angle is greater than 0 degrees. Specifically, it can be 30 degrees, 60 degrees, 70 degrees, or 90 degrees. The extension direction of the touch structure 300 has an angle with the bending axis 11, therefore, the included angle does not include 180°.

[0170] For example, in simulation analysis, the touch structure 300 with a certain angle to the bending axis 11 experiences a 28% reduction in force compared to the touch structure 300 parallel to the bending axis 11.

[0171] Please refer to Figures 10a and 10b, where Figure 10a is a partial top view of the display panel in another embodiment; and Figure 10b is a partial top view of the display panel in another embodiment.

[0172] As shown in Figures 10a and 10b, in some optional embodiments, the touch structure 300 includes a first segment 301 and a second segment 302 connected to each other, with an included angle greater than 90° between the first segment 301 and the second segment 302.

[0173] The angle between the first segment 301 and the second segment 302 is greater than 90°, which means that the angle between the extension direction of the first segment 301 and the extension direction of the second segment 302 is greater than 90°.

[0174] In these optional embodiments, the included angle between the interconnected first segment 301 and the second segment 302 is set to be large, which can reduce the sudden change in stiffness of the first segment 301 and the second segment 302 caused by the arching process of the display panel 10, and improve the problem that the large change in stiffness easily forms stress concentration points, thereby causing film layer breakage.

[0175] The first segment 301 and the second segment 302 can be configured in various ways. In some optional embodiments, the touch structure 300 includes a touch electrode and a touch connection line. One end of the touch connection line is connected to the touch electrode, and the other end of the touch connection line is used to connect to the touch integrated circuit. One of the first segment 301 and the second segment 302 is part of the touch electrode, and the other is part of the touch connection line. Alternatively, both the first segment 301 and the second segment 302 are part of the touch connection line.

[0176] Optionally, both the first segment 301 and the second segment 302 are part of the touch electrode.

[0177] Optionally, the touch electrode is a strip electrode.

[0178] In these optional embodiments, one of the first segment 301 and the second segment 302 is part of a touch electrode, and the other is part of a touch connection line. The included angle between the interconnected first segment 301 and the second segment 302 is set to be relatively large, which can reduce the sudden change in stiffness of the interconnected touch electrode and touch connection line caused by the arching process of the display panel 10, and improve the problem of large stiffness changes that easily form stress concentration points, thereby causing film layer breakage. In other embodiments, the first segment 301 and the second segment 302 are both part of touch connection lines, and the included angle between the interconnected first segment 301 and the second segment 302 is set to be relatively large, which can reduce the sudden change in stiffness of the interconnected touch connection lines caused by the arching process of the display panel 10, and improve the problem of large stiffness changes that easily form stress concentration points, thereby causing film layer breakage. In other embodiments, the first segment 301 and the second segment 302 are both part of the touch electrode. The included angle between the interconnected first segment 301 and the second segment 302 is set to be large, which can reduce the sudden change in stiffness of the interconnected touch electrodes caused by the anti-arching process of the display panel 10, and improve the problem that the stiffness change is large and stress concentration points are easily formed, thus causing film layer breakage.

[0179] As shown in Figure 10b, in some optional embodiments, the connection between the first segment 301 and the second segment 302 includes a chamfer; more specifically, the chamfer is a rounded chamfer.

[0180] In some alternative embodiments, the extension direction of the touch connection line has an angle with the bending axis 11.

[0181] In these optional embodiments, the extension direction of the touch connection line is not parallel to the bending axis 11 to avoid the problem that the extension direction of the touch connection line being parallel to the bending axis 11 would increase the sudden change in stiffness of the display panel 10 during the anti-arching process, forming a stress concentration point, and thus causing the film layer to break.

[0182] In some alternative embodiments, the orthographic projection of the touch structure 300 onto the substrate 100 has an edge parallel to the bending axis 11 of the display panel 10.

[0183] In these alternative embodiments, setting at least a portion of the edges of the touch structure 300 parallel to the bending axis 11 can improve the situation where the tip of the included angle of the touch structure 300 is set toward or away from the bending axis 11, which would increase the abrupt change in stiffness of the display panel 10 during the anti-arching process, forming stress concentration points and causing film layer breakage.

[0184] For example, in simulation analysis, the tip of the touch structure 300 that is angled toward or away from the bending axis 11 is replaced with an edge that is parallel to the bending axis 11, so that the force on the touch structure 300 at the edge position is reduced by 3% relative to the tip.

[0185] Please refer to Figure 11, which is a partial top view of the display panel in another embodiment.

[0186] As shown in FIG11, in some optional embodiments, two adjacent touch structures 300 are spaced apart to form a first gap 303, and the orthographic projection of the touch structure 300 on the substrate 100 has a first side 304 facing the first gap 303, at least a portion of the first side 304 being parallel to the bending axis 11.

[0187] In these alternative embodiments, setting at least a portion of the first side 304 of the touch structure 300 parallel to the bending axis 11 can improve the problem of the tip of the included angle of the touch structure 300 toward the first gap 303 being oriented or away from the bending axis 11, which would increase the abrupt stiffness change of the display panel 10 during the anti-arching process, forming stress concentration points and causing film layer breakage. For example, it can avoid X-shaped cracks caused by stress concentration.

[0188] Optionally, the first sides 304 of adjacent touch structures 300 facing the first gap 303 are all parallel to the bending axis 11, which can further reduce the sudden change in stiffness of the display panel 10 during the anti-arching process. Optionally, a portion of the first sides 304 of the plurality of touch structures 300 are parallel to the bending axis 11.

[0189] Please refer to Figure 12, which is a partial top view of the display panel in another embodiment.

[0190] As shown in Figure 12, in some optional embodiments, the first side 304 includes at least two sides connected in sequence, and the included angle between any two adjacent sides is greater than 90°.

[0191] In these optional embodiments, the first side 304 is divided into multiple interconnected sides, and the included angle between any two adjacent sides is set to be large. This can reduce the sudden change in stiffness of the end of the touch structure 300 facing the first gap 303 caused by the arching process of the display panel 10 screen body, and improve the problem that the large change in stiffness is easy to form stress concentration points, thereby causing film layer breakage.

[0192] Please refer to Figure 13, which is a partial top view of the display panel in another embodiment.

[0193] As shown in Figure 13, optionally, the first side 304 includes a curve, which can improve the situation where the tip of the included angle of the touch structure 300 is set towards or away from the bending axis 11, which would increase the stiffness of the screen of the display panel 10 during the anti-arching process, forming a stress concentration point and causing the film layer to break.

[0194] As shown in Figure 11, in some optional embodiments, the orthographic projection of the touch structure 300 on the substrate 100 also includes a second side 305 connected to both ends of the first side 304, and the angle between the second side 305 and the bending axis 11 is 45°.

[0195] In these alternative embodiments, the angle between the second side 305 and the bending axis 11 is 45°, which can improve the problem that the stiffness of the display panel 10 increases abruptly during the anti-arching process due to the small angle between the second side 305 and the bending axis 11, forming a stress concentration point and causing the film layer to break.

[0196] In some alternative embodiments, the included angle between the first side 304 and the second side 305 is greater than 90°.

[0197] In these alternative embodiments, setting the included angle between the first side 304 and the second side 305 to be larger can reduce the sudden change in stiffness of the end of the touch structure 300 facing the first gap 303 caused by the arching process of the display panel 10 screen body, and improve the problem that the large change in stiffness is easy to form stress concentration points, thereby causing film layer breakage.

[0198] Optionally, the included angle between any two adjacent sides of the orthographic projection of the touch structure 300 on the substrate 100 is greater than 90°, which can reduce the sudden change in stiffness of the touch structure 300 caused by the anti-arching process of the display panel 10, and improve the problem that the stiffness change is large and stress concentration points are easily formed, thus causing film layer breakage.

[0199] Please refer to Figure 14, which is a partial top view of the display panel in another embodiment.

[0200] As shown in Figure 14, optionally, the first touch structure 310 further includes a first conductive part 313, and the second touch structure 320 further includes a second conductive part 323, with the first conductive part 313 and the second conductive part 323 connected by a via.

[0201] Optionally, the orthographic projection of the second conductive portion 323 on the substrate 100 has a seventh edge 323a and an eighth edge 323b disposed opposite each other in a third direction Z, the third direction Z being perpendicular to the bending axis 11 of the display panel 10.

[0202] Optionally, the seventh edge 323a is parallel to the bending axis 11, and the eighth edge 323b is parallel to the bending axis 11.

[0203] Optionally, the length d3 of the seventh edge 323a is 3μm-15μm, for example, the length of the seventh edge 323a is 3μm, 5μm, 6μm, 15μm, etc.

[0204] In these optional embodiments, the first conductive portion 313 and the second conductive portion 323 are connected via vias to achieve electrical connection between the first touch structure 310 and the second touch structure 320. The seventh edge 323a and the eighth edge 323b are parallel to the bending axis 11. Therefore, the seventh edge 323a and the eighth edge 323b cause a sudden increase in stiffness during the anti-arching process of the display panel 10, forming stress concentration points and leading to film layer breakage. Setting the length of the seventh edge 323a to be less than or equal to 15 μm can mitigate the problem of excessive stiffness abruptness in the second conductive portion 323 due to an excessively large length of the seventh edge 323a, which leads to an excessively large stiffness abruptness during the anti-arching process of the display panel 10, forming stress concentration points and causing film layer breakage. Setting the length of the seventh edge 323a to be greater than or equal to 3 μm can mitigate the problem of increased fabrication difficulty of the second conductive portion 323 due to an excessively small length of the seventh edge 323a.

[0205] In some optional embodiments, the length d4 of the eighth edge 323b is 3μm-15μm, for example, the length of the eighth edge 323b is 3μm, 5μm, 6μm, 15μm, etc.

[0206] In these optional embodiments, the length of the eighth edge 323b is less than or equal to 15 μm. This can mitigate the problem that an excessively large length of the eighth edge 323b leads to an excessively large stiffness abrupt change area in the second conductive portion 323, resulting in increased stiffness abrupt changes during the anti-arching process of the display panel 10, forming stress concentration points, and thus causing film layer breakage. Conversely, a length of the eighth edge 323b greater than or equal to 3 μm can mitigate the problem that an excessively small length of the eighth edge 323b increases the difficulty of fabricating the second conductive portion 323.

[0207] For example, when the lengths of the seventh edge 323a and the eighth edge 323b are reduced to 3 μm, the force at the locations of the first conductive part 313 and the second conductive part 323 is reduced by 16% relative to the lengths of the seventh edge 323a and the eighth edge 323b being 10 μm.

[0208] In some alternative embodiments, the orthographic projection of the second conductive portion 323 onto the substrate 100 has a ninth edge 323c and a tenth edge 323d disposed opposite each other in a fourth direction W, the fourth direction W being parallel to the bending axis 11 of the display panel 10.

[0209] Optionally, the ninth edge 323c is perpendicular to the bending axis 11, and the tenth edge 323d is perpendicular to the bending axis 11.

[0210] In some optional embodiments, the length d5 ​​of the ninth edge 323c is 3μm-15μm, for example, the length of the ninth edge 323c is 3μm, 5μm, 6μm, 15μm, etc.

[0211] In these optional embodiments, the length of the ninth edge 323c is less than or equal to 15 μm. This can mitigate the problem that an excessively large length of the ninth edge 323c results in an excessively large abrupt change in the stiffness of the second conductive portion 323, leading to an increased stiffness abrupt change during the anti-arching process of the display panel 10, forming stress concentration points, and thus causing film layer breakage. Conversely, a length of the ninth edge 323c greater than or equal to 3 μm can mitigate the problem that an excessively small length of the ninth edge 323c increases the difficulty of fabricating the second conductive portion 323.

[0212] In some optional embodiments, the length d6 of the tenth edge 323d is 3μm-15μm, for example, the length of the tenth edge 323d is 3μm, 5μm, 6μm, 15μm, etc.

[0213] In these optional embodiments, the length of the tenth edge 323d is less than or equal to 15 μm. This can mitigate the problem that an excessively large length of the tenth edge 323d results in an excessively large stiffness abrupt change area in the second conductive portion 323, leading to increased stiffness abrupt changes during the anti-arching process of the display panel 10, forming stress concentration points, and thus causing film layer breakage. A length of the tenth edge 323d is greater than or equal to 3 μm. This can mitigate the problem that an excessively small length of the tenth edge 323d increases the difficulty of fabricating the second conductive portion 323.

[0214] Optionally, the length of the edge of the first conductive portion 313 projected onto the substrate 100 and parallel to the bending axis 11 is 3μm-15μm, for example, the length of the edge is 3μm, 5μm, 6μm, 15μm, etc.

[0215] In these optional embodiments, the length of the edge of the first conductive portion 313 parallel to the bending axis 11 on the substrate 100 is less than or equal to 15 μm. This can mitigate the problem of excessive stiffness abruptness and stress concentration points caused by an excessively long edge of the first conductive portion 313, which leads to increased stiffness abruptness during the anti-arching process of the display panel 10 and thus film layer breakage. Alternatively, the length of the edge of the first conductive portion 313 parallel to the bending axis 11 on the substrate 100 is greater than or equal to 3 μm. This can mitigate the problem of increased fabrication difficulty of the first conductive portion 313 due to an excessively short edge.

[0216] Optionally, the length of the edge of the first conductive portion 313 projected onto the substrate 100 and perpendicular to the bending axis 11 is 3μm-15μm, for example, the length of the edge is 3μm, 5μm, 6μm, 15μm, etc.

[0217] In these optional embodiments, the length of the edge of the first conductive portion 313 perpendicular to the bending axis 11 on the substrate 100 is less than or equal to 15 μm. This can mitigate the problem of excessive stiffness abruptness in the first conductive portion 313 due to its excessively long edge, which leads to stress concentration points and film layer breakage during the anti-arching process of the display panel 10. Alternatively, the length of the edge of the first conductive portion 313 perpendicular to the bending axis 11 on the substrate 100 is greater than or equal to 3 μm. This can mitigate the problem of increased fabrication difficulty of the first conductive portion 313 due to its excessively short edge.

[0218] Please refer to Figure 15, which is a partial top view of the display panel in another embodiment.

[0219] As shown in Figure 15, optionally, the second conductive layer 220 further includes a third chamfered segment 325 and a third main body portion 324, with the third chamfered segment 325 located between the second conductive portion 323 and the third main body portion 324.

[0220] Optionally, the angle between the third chamfered segment 325 and the second conductive portion 323 is an obtuse angle. The angle between the third chamfered segment 325 and the second conductive portion 323 refers to the angle between the adjacent edges of the third chamfered segment 325 and the second conductive portion 323.

[0221] In these alternative embodiments, setting the included angle between the third chamfered segment 325 and the second conductive portion 323 to a larger value can reduce the sudden change in stiffness of the touch structure 300 caused by the arching process of the display panel 10 screen body, and improve the problem that the second conductive layer 220 has a large sudden change in stiffness, which easily forms stress concentration points and thus causes film layer breakage.

[0222] In some optional embodiments, the included angle between the third chamfered segment 325 and the third main body portion 324 is an obtuse angle. The included angle between the third chamfered segment 325 and the third main body portion 324 refers to the included angle between adjacent edges of the third chamfered segment 325 and the third main body portion 324.

[0223] In these alternative embodiments, setting the included angle between the third chamfered segment 325 and the third main body 324 to a larger value can reduce the sudden change in stiffness of the touch structure 300 caused by the arching process of the display panel 10 screen body, and improve the problem that the second conductive layer 220 has a large sudden change in stiffness, which easily forms stress concentration points and thus causes film layer breakage.

[0224] In some alternative embodiments, the third chamfer segment 325 includes a curve.

[0225] When the third chamfered segment 325 is curved, the angle between the third chamfered segment 325 and the second conductive part 323 refers to the angle between the tangent direction at the contact point between the third chamfered segment 325 and the second conductive part 323 and the edge of the second conductive part 323. The angle between the third chamfered segment 325 and the third main body part 324 refers to the angle between the tangent direction at the contact point between the third chamfered segment 325 and the third main body part 324 and the edge of the second conductive part 323.

[0226] In these alternative embodiments, a smooth transition with a curve is adopted between the second conductive part 323 and the third main body part 324, which can further reduce the sudden change in stiffness of the touch structure 300 caused by the anti-arching process of the display panel 10 screen body, and improve the problem that the second conductive layer 220 has a large sudden change in stiffness, which is prone to stress concentration points and thus film layer breakage.

[0227] Optionally, the length of at least a portion of the edge of the touch structure 300 projected onto the substrate 100 that is parallel to the bending axis 11 can be reduced to one-quarter to three-quarters of its original length. For example, if the original length of an edge is d, the length can be reduced to 0.25d to 0.75d. This reduces the area of ​​stiffness abrupt change in the touch structure 300, thereby reducing the stiffness abrupt change in the touch structure 300 and improving the problem of large stiffness abrupt changes during the anti-arching process of the display panel 10, which can lead to stress concentration points and film layer breakage.

[0228] Optionally, the display panel 10 further includes a pixel definition layer, a light-emitting layer, a first electrode layer, and an encapsulation layer, which are sequentially stacked on one side of the substrate 100 and along the thickness direction of the display panel 10. The touch layer 200 is located on the side of the encapsulation layer opposite to the substrate 100.

[0229] As shown in Figures 1 to 15, a second aspect embodiment of this application provides a display panel 10, which includes: a substrate 100; a touch layer 200 located on one side of the substrate 100, the touch layer 200 including a first conductive layer 210, an insulating layer 230 and a second conductive layer 220 stacked sequentially, the second conductive layer 220 being located on the side of the first conductive layer 210 away from the substrate 100; wherein, the touch layer 200 includes a touch structure 300, the touch structure 300 including touch electrodes and touch connection lines, the display panel 10 having a bending axis 11 in the bending region 12, and at least a portion of the extension direction of the touch connection lines having an angle with the bending axis 11.

[0230] According to an embodiment of this application, the display panel 10 includes a substrate 100 and a touch layer 200. The touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220. At least some of the touch connection lines are not parallel to the bending axis 11, so as to avoid the problem that the stiffness of the display panel 10 screen would increase abruptly during the anti-arching process due to the parallel arrangement of the touch connection lines with the bending axis 11, forming stress concentration points and causing film layer breakage.

[0231] After the aforementioned improvements, the display panel 10 provided in this application underwent a parallel plate test under an outward folded state. Two parallel plates were used to clamp and compress the display panel 10, and the plate spacing was measured to simulate the display panel 10's ability to resist outward folding and arching after a drop. Experiments verified that the plate spacing between the two parallel plates changed from 4.1mm to 3.5mm before the improvement. Before the improvement, when the plate spacing was adjusted to 4.1mm, cracks appeared in the display panel 10. After the improvement, when the plate spacing was adjusted to 3.5mm, cracks only appeared in the display panel 10. Immediately, the display panel 10's resistance to compression under outward folding conditions was improved, demonstrating a significant improvement effect. Therefore, the display panel 10 provided in this application improves the problem of film layer cracking caused by stress concentration.

[0232] The structural design in this embodiment can be applied to other display panels 10. The specific choice can be made according to the actual situation, and this application does not impose any specific restrictions on it.

[0233] As shown in Figures 10a and 10b, in some optional embodiments, the touch structure 300 includes a first segment 301 and a second segment 302 connected to each other, with an included angle greater than 90° between the first segment 301 and the second segment 302.

[0234] The angle between the first segment 301 and the second segment 302 is greater than 90°, which means that the angle between the extension direction of the first segment 301 and the extension direction of the second segment 302 is greater than 90°.

[0235] Optionally, all touch connection lines extend at an angle to the bending axis 11. This further avoids stress concentration points, which could lead to membrane breakage.

[0236] As shown in FIG11, in some optional embodiments, two adjacent touch structures 300 are spaced apart to form a first gap 303, and the orthographic projection of the touch structure 300 on the substrate 100 has a first side 304 facing the first gap 303, at least a portion of the first side 304 being parallel to the bending axis 11.

[0237] Optionally, the first side 304 of the adjacent touch structures 300 facing the first gap 303 is parallel to the bending axis 11, which can further reduce the sudden change in stiffness of the display panel 10 during the anti-arching process.

[0238] As shown in Figure 12, in some optional embodiments, the first side 304 includes at least two sides connected in sequence, and the included angle between any two adjacent sides is greater than 90°.

[0239] In these optional embodiments, the first side 304 is divided into multiple interconnected sides, and the included angle between any two adjacent sides is set to be large. This can reduce the sudden change in stiffness of the end of the touch structure 300 facing the first gap 303 caused by the arching process of the display panel 10 screen body, and improve the problem that the large change in stiffness is easy to form stress concentration points, thereby causing film layer breakage.

[0240] As shown in Figure 11, in some optional embodiments, the orthographic projection of the touch structure 300 on the substrate 100 also includes a second side 305 connected to both ends of the first side 304, and the angle between the second side 305 and the bending axis 11 is 45°.

[0241] In these alternative embodiments, the angle between the second side 305 and the bending axis 11 is 45°, which can improve the problem that the stiffness of the display panel 10 increases abruptly during the anti-arching process due to the small angle between the second side 305 and the bending axis 11, forming a stress concentration point and causing the film layer to break.

[0242] In some alternative embodiments, the included angle between the first side 304 and the second side 305 is greater than 90°.

[0243] Optionally, as shown in Figures 1 to 4, the touch structure 300 includes a first touch structure 310 located on the first conductive layer 210 and a second touch structure 320 located on the second conductive layer 220. The first touch structure 310 includes a first segment 311, and the second touch structure 320 includes a second segment 321. Both the first segment 311 and the second segment 321 extend along the first direction X. The orthographic projection of the first segment 311 on the substrate 100 and the orthographic projection of the second segment 321 on the substrate 100 at least partially overlap. The orthographic projections of the first segment 311 on at least one side of the second direction Y and the second segment 321 on the same side of the second direction Y are offset on the substrate 100, and the first direction X and the second direction Y intersect.

[0244] In some optional embodiments, the orthographic projection of the first segment 311 on the substrate 100 has a first edge 311a and a second edge 311b disposed opposite to each other in the second direction Y, and the orthographic projection of the second segment 321 on the substrate 100 has a third edge 321a and a fourth edge 321b disposed opposite to each other in the second direction Y. The first edge 311a and the third edge 321a are located on the same side, the second edge 311b and the fourth edge 321b are located on the same side, the first edge 311a and the third edge 321a are offset, and / or the second edge 311b and the fourth edge 321b are offset.

[0245] Specifically, the first edge 311a and the third edge 321a may be misaligned; or the second edge 311b and the fourth edge 321b may be misaligned; or the first edge 311a and the third edge 321a may be misaligned, and the second edge 311b and the fourth edge 321b may be misaligned.

[0246] Optionally, the first edge 311a and the second edge 311b are parallel, and / or the third edge 321a and the fourth edge 321b are parallel, and / or the third edge 321a and the first edge 311a are parallel, and / or the fourth edge 321b and the second edge 311b are parallel.

[0247] Optionally, the first edge 311a, the second edge 311b, the third edge 321a, and the fourth edge 321b are all parallel.

[0248] As shown in FIG2, in some optional embodiments, the insulating layer 230 includes a first flat portion 231, a slope 232 and a second flat portion 233 connected in sequence. The second flat portion 233 is located on the side of the first flat portion 231 away from the substrate 100. The slope 232 and the first flat portion 231 have an intersecting position. The orthographic projection of the intersecting position on the substrate 100 is located within the orthographic projection of the second segment 321 on the substrate 100.

[0249] In these alternative embodiments, when the intersection of the insulating layer 230 is covered by the second segment 321, and the orthographic projection of the edge of the first segment 311 on one side in the second direction Y and the edge of the second segment 321 on the same side on the substrate 100 is misaligned, the stress at the intersection where stress concentration is likely to occur is reduced, thereby improving the problem of the insulating layer 230 film layer cracking caused by stress concentration at the intersection.

[0250] In some alternative embodiments, the orthographic projections of the first flat portion 231 and the second flat portion 233 on the substrate 100 at least partially overlap with the orthographic projection of the second segment 321 on the substrate 100.

[0251] Optionally, the orthographic projection of the second flat portion 233 on the substrate 100 at least partially overlaps with the orthographic projection of the first segment 311 on the substrate 100.

[0252] Optionally, the orthographic projection of the slope 232 and at least part of the second flat portion 233 on the substrate 100 lies within the orthographic projection of the second segment 321 on the substrate 100.

[0253] Optionally, at least a portion of the first flat portion 231 may have its orthographic projection on the substrate 100 located within the orthographic projection of the second segment 321 on the substrate 100.

[0254] In some alternative embodiments, the orthographic projection of the intersecting position on the substrate 100 is outside the orthographic projection of the first segment 311 on the substrate 100.

[0255] In some optional embodiments, the first touch structure 310 further includes a first conductive portion 313, and the second touch structure 320 further includes a second conductive portion 323, with the first conductive portion 313 and the second conductive portion 323 connected via a via.

[0256] Optionally, the orthographic projection of the second conductive portion 323 on the substrate 100 has a seventh edge 323a and an eighth edge 323b disposed opposite each other in a third direction Z, the third direction Z being perpendicular to the bending axis 11 of the display panel 10.

[0257] Optionally, the seventh edge 323a is parallel to the bending axis 11, and the eighth edge 323b is parallel to the bending axis 11.

[0258] Optionally, the length d3 of the seventh edge 323a is 3μm-15μm, for example, the length of the seventh edge 323a is 3μm, 5μm, 6μm, 15μm, etc. The length d4 of the eighth edge 323b is 3μm-15μm, for example, the length of the eighth edge 323b is 3μm, 5μm, 6μm, 15μm, etc.

[0259] In some alternative embodiments, the orthographic projection of the second conductive portion 323 onto the substrate 100 has a ninth edge 323c and a tenth edge 323d disposed opposite each other in a fourth direction W, the fourth direction W being parallel to the bending axis 11 of the display panel 10.
