[0046] Embodiment one

[0047] In the related art, for example, Figure 1As shown, a display panel with a refractive film layer typically includes a substrate 100' and several traces 200' disposed on the substrate 100'. The refractive film layer (not shown in the figure) is disposed on the side of the traces 200' facing away from the substrate 100'. The traces 200' are arranged parallel to each other and spaced apart within the bezel area NA'. Because the terrain is lower at the gap 300' between adjacent traces 200', the flowing refractive medium preferentially flows into the gap 300' before the refractive film layer solidifies. When the display panel is not horizontal (the display panel is placed vertically or tilted), the refractive medium flowing within the gap 300' flows in the direction away from the display area AA' under the influence of gravity, i.e., along... Figure 1 The flow in the D1 direction causes the flowing refractive medium to be unevenly distributed on the display panel. When the flowing refractive medium solidifies into a refractive film layer, the uneven distribution of the refractive film layer on the display panel can easily lead to abnormal problems such as bubbles in the support film of the screen section and small white spots on the periphery of the module section.

[0048] To address the aforementioned technical problems, this embodiment provides a display panel that can reduce the flow rate of the refractive medium towards the side of the frame area NA away from the display area AA, thereby improving the uniformity of the refractive film layer distribution on the display panel.

[0049] Specifically, such as Figures 2 to 5 As shown, the display panel has a bezel area NA and a display area AA, with the bezel area NA surrounding the display area AA. The display panel includes a substrate 100, traces, and a refractive film layer 600. The traces are disposed on the substrate 100, with at least a portion of the traces located within the bezel area NA. At least a portion of the traces located within the bezel area NA are bent. The refractive film layer 600 is disposed on the side of the traces facing away from the substrate 100. In this embodiment, the refractive film layer 600 is a high refractive index film layer.

[0050] Based on the above design, at least some of the traces in the bezel area NA are bent. Before the refractive film layer 600 is cured, it is a flowing refractive medium. The bent part of the traces can have a certain retention effect on the flowing refractive medium, thereby reducing the flow of the flowing refractive medium to the side of the bezel area NA away from the display area AA. This makes the refractive film layer 600 formed by the curing of the flowing refractive medium more uniformly distributed on the display panel, thus achieving the effect of improving the uniformity of the distribution of the refractive film layer 600 on the display panel.

[0051] Furthermore, such as Figures 2 to 5As shown, the wires include a first wire 310, the frame area NA includes a first area 410, at least part of the first wire 310 is located in the first area 410, and the orthographic projection of the first wire 310 on the substrate 100 in the first area 410 extends in a direction of the frame area NA away from the display area AA, so that the flowing refractive medium can flow on both sides of the first wire 310, and part of the flowing refractive medium can stay in the bent part of the first wire 310, that is, the flowing path of the flowing refractive medium is not completely blocked, but the flow of the flowing refractive medium away from the display area AA to the side of the frame area NA is reduced, so that after the flowing refractive medium solidifies to form the refractive film layer 600, the uniformity of the distribution of the refractive film layer 600 on the display panel is higher.

[0052] Optionally, the orthographic projection of the first wire 310 in the first area 410 on the substrate 100 can be a wavy shape or a continuous V shape, etc., which can be determined according to actual production conditions.

[0053] Optionally, as shown, Figures 2 to 5 The display panel further includes an insulating layer 200 arranged on the substrate 100, the insulating layer 200 is located on the side of the wires away from the substrate 100, at least part of the insulating layer 200 is located in the frame area NA, a plurality of grooves 210 are arranged on at least part of the insulating layer 200 located in the frame area NA, the plurality of grooves 210 are all located on the side of the insulating layer 200 away from the substrate 100, and the refractive film layer 600 is arranged on the side of the insulating layer 200 away from the substrate 100. When the flowing refractive medium flows through the grooves 210, part of the flowing refractive medium can stay in the grooves 210, further reducing the flow of the flowing refractive medium to the side of the frame area NA away from the display area AA, and improving the uniformity of the distribution of the refractive film layer 600 on the display panel.

[0054] It should be noted that in the embodiment, the direction from the display area AA to the frame area NA is the D1 direction in Figure 2 , and the direction from the frame area NA to the display area AA is the D2 direction in Figure 2 , so the direction of the frame area NA away from the display area AA is the D1 direction in Figure 2 , and the plurality of grooves 210 reduce the flow of the flowing refractive medium in the D1 direction.

[0055] Optionally, the insulating layer 200 can be an organic insulating layer or an inorganic insulating layer, etc.

[0056] Further, as shown, Figures 2 to 5As shown, the frame area NA further includes a second area 420, and the plurality of grooves 210 are all located in the second area 420, and the first area 410 and the second area 420 are arranged in the direction from the display area AA to the frame area NA, when the flowing refractive medium flows through the first area 410, part of the flowing refractive medium is retained at the bending part of the first trace 310 located in the first area 410, and when the flowing refractive medium flows through the second area 420, part of the flowing refractive medium is retained in the groove 210, thereby forming two retention areas of the flowing refractive medium in the D1 direction. Compared with the arrangement that the first area 410 and the second area 420 are staggered with each other in the D1 direction, the technical solution provided in the embodiment can further reduce the flow of the flowing refractive medium in the D1 direction, and has the effect of further improving the uniformity of the distribution of the refractive film layer 600 on the display panel after the flowing refractive medium is solidified.

[0057] Further, as shown in FIG. 4, the first area 410 and the second area 420 are arranged in sequence in the direction from the display area AA to the frame area NA. Figures 2 to 5 As shown, the first area 410 and the second area 420 are arranged in sequence in the direction from the display area AA to the frame area NA, when the display panel is in a non-horizontal state, especially when the display panel is placed vertically, the flowing refractive medium retained in the groove 210 is easy to overflow from the groove 210 (i.e., the retention of the flowing refractive medium by the groove 210 fails), and the overflowing flowing refractive medium flows in the D1 direction under the action of gravity, while the flowing refractive medium retained at the bending part of the first trace 310 has a lower probability of overflowing compared with the flowing refractive medium retained in the groove 210. Therefore, the first area 410 is arranged on the side of the second area 420 facing the display area AA, and the flowing refractive medium flowing from the display area AA to the frame area NA passes through the first area 410 and then passes through the second area 420, thereby reducing the amount of the flowing refractive medium entering the second area 420, and reducing the overflow amount of the flowing refractive medium when the retention of the flowing refractive medium by the groove 210 fails.

[0058] Of course, in other embodiments, the second area 420 and the first area 410 can also be arranged in sequence in the direction from the display area AA to the frame area NA, i.e., the second area 420 is located on the side of the first area 410 facing the display area AA, which can be determined according to actual application requirements.

[0059] Further, as shown in FIG. 4, the first area 410 and the second area 420 are arranged in sequence in the direction from the display area AA to the frame area NA. Figures 2 to 5 As shown, the plurality of grooves 210 are uniformly distributed in the second area 420. It should be noted that the specific number of grooves 210 can be thirty, forty or even more, which can be determined according to the specific size of the frame area NA and the total amount of the flowing refractive medium.

[0060] Optionally, as shown in FIG. 4, the plurality of grooves 210 are arranged in the second area 420 in a staggered manner. Figures 2 to 5As shown, the traces further include a second trace 320, at least part of the second trace 320 is located in the first region 410, in the first region 410, the second trace 320 is located on the side of the first trace 310 away from the substrate 100, in the first region 410, the orthographic projection of the second trace 320 on the substrate 100 extends in a direction of the display area AA towards the frame area NA, and in the first region 410, the bending angles of the plurality of bending positions of the orthographic projection of the second trace 320 on the substrate 100 correspond to and are equal to the bending angles of the plurality of bending positions of the orthographic projection of the first trace 310 on the substrate 100, the structure design makes the first trace 310 and the second trace 320 form a stacked structure in the first region 410, thereby increasing the total height of the traces in the first region 410, and further increasing the retention amount of the flowing refractive medium in the first region 410, further reducing the flowing refractive medium entering the second region 420, and further improving the uniformity of the distribution of the refractive film layer 600 on the display panel.

[0061] Optionally, as shown in FIG. 6B, Figures 2 to 5 As shown, part of the first trace 310 is located in the second region 420, it should be noted that the orthographic projection of the first trace 310 located in the second region 420 on the substrate 100 can be in various forms, for example: in the present embodiment, the orthographic projection of the first trace 310 located in the second region 420 on the substrate 100 is a straight line parallel to the D1 direction, of course, in other embodiments, the orthographic projection of the first trace 310 located in the second region 420 on the substrate 100 can be a straight line at an angle with the D1 direction, or can be a shape extending in a direction of the display area AA towards the frame area NA.

[0062] Further, as shown in FIG. 6B, Figures 2 to 5 As shown, the display panel further includes a deposition layer 500 disposed on the substrate 100, the deposition layer 500 is located on the side of the insulating layer 200 away from the substrate 100, at least part of the deposition layer 500 is located in the second region 420 and is clamped between the insulating layer 200 and the first trace 310, the orthographic projection of the plurality of grooves 210 on the substrate 100 and the orthographic projection of the first trace 310 on the substrate 100 in the second region 420 are located within the orthographic projection of the deposition layer 500 on the substrate 100, the structure design plays a protective role for the first trace 310 in the second region 420, the thickness of the region of the insulating layer 200 where the groove 210 is opened is thinned, the flowing refractive medium retained in the groove 210 is easy to corrode the first trace 310 in the second region 420, and the deposition layer 500 plays a role of blocking the flowing refractive medium from corroding.

[0063] Further, the deposition layer 500 can be a chemical vapor deposition layer or a physical vapor deposition layer, etc., which can be determined according to actual application requirements and production requirements.

[0064] Optionally, the border area includes a top border area, a bottom border area, a left border area, and a right border area. In this embodiment, the border area NA is the bottom border area. Of course, in other implementations, the border area NA can also be at least one of the top border area, the bottom border area, the left border area, and the right border area, depending on the actual usage requirements.

[0065] Optionally, such as Figures 2 to 5 As shown, the border area NA also includes a third region 430. The third region 430 is located on the side of the first region 410 and the second region 420 that is away from the display area AA. In this embodiment, the third region 430 is located on the side of the second region 420 that is away from the first region 410. The trace also includes a third trace 330. At least a portion of the third trace 330 is located in the third region 430. It should be noted that the orthographic projection of the third trace 330 located in the third region 430 on the substrate 100 can be in various forms. For example, in this embodiment, the orthographic projection of the third trace 330 located in the third region 430 on the substrate 100 is a straight line parallel to the D1 direction. Of course, in other embodiments, the orthographic projection of the third trace 330 located in the third region 430 on the substrate 100 can be a straight line at an angle to the D1 direction, or it can be a shape that bends and extends along the direction from the display area AA toward the border area NA.

[0066] In this embodiment, as Figure 5 As shown, in the first region 410, the substrate 100 is sequentially provided with a bent first trace 310, a deposition layer 500, a bent second trace 320, and an insulating layer 200. Although both the bent first trace 310 and the bent second trace 320 are covered by the insulating layer 200, the insulating layer 200 is relatively thin, so its presence does not affect the retention effect of the bent portions of the first trace 310 and the second trace 320 on the flowing refractive medium. In the second region 420, the substrate 100 is sequentially provided with a first trace 310, a deposition layer 500, and an insulating layer 200. In the third region 430, the substrate 100 is sequentially provided with a deposition layer 500, a third trace 330, and an insulating layer 200.

[0067] In this embodiment, as Figure 5As shown, the first traces 310 extend from the first region 410 to the second region 420, the first traces 310 in the first region 410 are in a meandering shape, the first traces 310 in the second region 420 are in a straight line shape, the second traces 320 are in a meandering shape and are located in the first region 410, the second traces 320 are located on the side of the first traces 310 away from the substrate 100 (i.e. the second traces 320 and the first traces 310 are in different layers), and the second traces 320 are overlapped with the first traces 310 in the second region 420. The third traces 330 are in a straight line shape and are located in the third region 430, and the third traces 330 are located on the same layer as the second traces 320, i.e. the distance between the third traces 330 and the substrate 100 is equal to the distance between the second traces 320 and the substrate 100, and the third traces 330 are overlapped with the first traces 310 in the second region 420.

[0068] In this embodiment, the number of the first traces 310, the second traces 320 and the third traces 330 are all multiple and one-to-one correspondence, i.e. in the first region 410, the side of each first trace 310 away from the substrate 100 is provided with a second trace 320, and each first trace 310 in the first region 410 extends to the second region 420 along the D1 direction, and in the third region 430, each third trace 330 is electrically connected with a first trace 310 in the second region 420.

[0069] Further, as shown in FIG. 4, the first traces 310 in the second region 420 are in a straight line shape, and the second traces 320 in the second region 420 are in a meandering shape. Figures 2 to 5As shown, in the first area 410, two adjacent first wires 310 are arranged at intervals so that part of the flowing refractive medium can flow in the first area 410; in the second area 420, two adjacent first wires 310 are arranged at intervals in a direction perpendicular to the D1 direction so that part of the flowing refractive medium can flow in the second area 420; in the third area 430, two adjacent third wires 330 are arranged at intervals in a direction perpendicular to the D1 direction so that part of the flowing refractive medium can flow in the third area 430. It should be noted that the flowing refractive medium flowing in the first area 410, the second area 420 and the third area 430 is not contradictory to the scheme that part of the flowing refractive medium is retained in the first area 410 and the second area 420. The structure design can make part of the flowing refractive medium be retained at the bending part of the first wire 310 in the first area 410, part of the flowing refractive medium be retained in the groove 210 in the second area 420, and the remaining flowing refractive medium can flow in the first area 410, the second area 420 and the third area 430, so that the distribution of the flowing refractive medium in different positions in the frame area NA is more uniform, and then the distribution of the refractive medium 600 formed by the flowing refractive medium in different positions in the frame area NA is more uniform, preventing the frame area NA (especially the side of the frame area NA away from the display area AA) from being abnormal.

[0070] Optionally, as shown in FIG. 6, the frame area NA further includes a dam area 440, the dam area 440 is located on the side of the first area 410 facing the display area AA, and the first wire 310 and the second wire 320 in the first area 410 both extend into the dam area 440. Figures 2 to 5

[0071] The embodiment also provides a display module, which includes the display panel described above, so that the distribution of the refractive film layer 600 on the display panel of the display module is more uniform.

[0072] The embodiment also provides a display device, which includes the display panel described above, or the display module described above, so that the distribution of the refractive film layer 600 on the display panel of the display device is more uniform.

[0074] The embodiment provides a display panel, which is different from the display panel provided in Embodiment One in that:

[0075] As shown in FIG. 6, the display panel includes a display area AA and a frame area NA surrounding the display area AA. Figure 6 ​As shown, the orthographic projection of the third trace 330 located in the third region 430 on the substrate 100 bends and extends along the direction from the display area AA toward the bezel area NA, so that the third region 430 forms a third retention area. Part of the refractive medium flowing through the third region 430 is retained at the bend of the third trace 330 in the third region 430, further reducing the flow of the refractive medium toward the edge of the bezel area NA (the side of the bezel area NA away from the display area AA).

[0076] Optionally, the orthographic projection of the third trace 330 of the third region 430 onto the substrate 100 can be wavy or continuous V-shaped, depending on the actual production situation.

[0077] The remaining structure of the display panel provided in this embodiment is the same as that in Embodiment 1, and will not be described again.

In the second region 420, part of the flowing refractive medium is retained in the groove 210 of the insulating layer 200, and part of the flowing refractive medium is retained at the bend of the first trace 310, further reducing the flow of the flowing refractive medium toward the edge of the bezel area NA (the side of the bezel area NA away from the display area AA).

[0081] Optionally, the orthographic projection of the first trace 310 in the second region 420 onto the substrate 100 can be wavy or continuous V-shaped, depending on the actual production situation.

[0082] The remaining structure of the display panel provided in this embodiment is the same as that in Embodiment 1, and will not be described again.
