DETAILED DESCRIPTION

[0090] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0091] Hereinafter, although terms such as "first", "second", etc. may be used to describe various components, these components are not necessarily limited to the above terms. The above terms are only used to distinguish one component from another. It will also be understood that expressions used in the singular include plural expressions unless the expression in the singular has an obviously different meaning in the context.

[0092] In the description of the present application, it should be noted that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0093] In some display panels, in order to reduce the difficulty of the evaporation process of the light-emitting material, an isolation structure is arranged on the first insulating layer between the pixel openings. When the light-emitting material layer and the cathode layer are evaporated throughout the entire layer, the light-emitting material layer and the cathode layer between adjacent pixel openings can be disconnected at the position of the isolation structure. Through multiple evaporation and multiple etching processes, corresponding pixel unit film layers can be formed in the pixel openings corresponding to light-emitting devices of different colors, and different light-emitting devices are packaged using separate packaging units.

[0094] Patent PCT / CN2023 / 134518, patent 202310759370.2, patent 202310740412.8, patent 202310707209.0, patent 202311499823.9, and patent 202311346196.5 record relevant technical solutions of isolation structure and encapsulation layer, and their contents are incorporated into this application by reference for reference.

[0095] The inventors have found that the above-mentioned display panel can achieve pixel-level packaging by using a photolithography process, and at this time, the power supply voltage signal (for example, ELVSS) can be transmitted through the isolation structure. For example, the power supply voltage signal can be provided by connecting the conductive traces of the lower frame to the isolation structure of the display area. However, in this display panel, the winding originally designed in the frame area for transmitting the power supply voltage signal has no practical function, which will cause a waste of space in the frame area, which is not conducive to achieving a narrow frame design and an increase in the screen-to-body ratio.

[0096] In order to further narrow the border of the display panel, the inventor innovatively designed the following technical solution to solve the above technical problems. The specific implementation scheme of this application will be described in detail below in conjunction with the accompanying drawings. It should be noted that the defects in the above solutions in the prior art are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above technical problems and the solutions proposed in this embodiment below for the above problems should all be the contributions made by the inventor to this application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0097] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 The schematic diagram of the regional distribution of the display panel provided by this embodiment is illustrated. Figure 1 is a top view, Figure 2 The first trace and gate drive circuit are shown in Figure 1 The distribution diagram of Figure 3 for Figure 2 A partial cross-sectional schematic diagram of the first area and the second area in the MM direction. In the present embodiment, exemplarily, the display panel 1 includes a display area 10 and a frame area 20, the frame area 20 is arranged around at least a portion of the display area 10, the display area 10 is used to display an image, and the frame area 20 can be set to provide various signal routings for the light-emitting devices in the display area 10 to provide electrical signals and arrange a gate drive circuit (Gate in panel, GIP circuit). Exemplarily, taking the shape of the display panel 1 as a rectangle as an example, the display area 10 can be a rectangle, the frame area 20 can be a rectangular ring surrounding the display area 10, and the frame area 20 can be formed by enclosing an upper frame area, a lower frame area, a left frame area and a right frame area. The frame area 20 may be located in a non-display area of ​​the display panel.

[0098] The display panel 1 includes a substrate 1101, a first wiring 1201 and a gate drive circuit 130, wherein the first wiring 1201 is located on one side of the substrate 1101, the first wiring 1201 is located in the frame area 20, and the gate drive circuit 130 is also located in the frame area 20. The first wiring 1201 is a wiring that at least partially surrounds the display area 10, the first wiring 1201 is connected to the gate drive circuit 130, and the first wiring 1201 provides a gate drive voltage for the gate drive circuit 130. The frame area 20 includes a plurality of sub-frame areas, and the first wiring 1201 is located in at least two sub-frame areas, wherein at least two of the plurality of sub-frame areas have different extension directions, and the plurality of sub-frame areas can be connected in sequence. In the present embodiment, the first wiring 1201 is a wiring originally used to transmit a power supply voltage signal (e.g., an ELVSS signal).

[0099] In the above structure, the wiring originally used to transmit the power supply voltage signal in the display panel border area 20 is used as the first wiring 1201 to provide the gate drive voltage, and the wiring providing the gate drive voltage in the gate drive circuit 130 can be cancelled. In this way, the layout space of the gate drive circuit 130 can be further compressed to reduce the width of the border area 20, further improve the screen-to-body ratio of the display panel 1, improve the user experience, and enhance the market competitiveness of the product.

[0100] Specifically, the orthographic projection of the first routing line 1201 on the substrate 1101 may not overlap with the orthographic projection of the gate driving circuit 130 on the substrate 1101 (that is, the orthographic projection of the first routing line 1201 on the substrate 1101 is outside the orthographic projection of the gate driving circuit 130 on the substrate 1101), and the orthographic projection of the first routing line 1201 on the substrate 1101 may also overlap with the orthographic projection of the gate driving circuit 130 on the substrate 1101.

[0101] Further, please refer again to Figure 1 and Figure 2 The display panel 1 further includes a first area 201 and a second area 202, both of which are located in the frame area 20, wherein the first area 201 can be arranged around the display area 10 of the display panel 1. At least part of the first wiring 1201 is located in the first area 201, and the gate driving circuit 130 is located in the second area 202. Optionally, in this embodiment, the second area 202 is located in the frame area 20 on opposite sides of the display area 10, and the second area 202 is located on the side of the first area 201 facing the display area 10.

[0102] Please refer to Figure 4 , Figure 5 and Figure 6 In the first area 201, the display panel includes a first dam structure 141 and a second dam structure 142 located on one side of the substrate 1101, and the first dam structure 141 and the second dam structure 142 are arranged around the display area 10. The orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101 are annular, and the specific shape of the annular can be similar to the outline shape of the display area 10. For example, when the outline shape of the display area 10 is rectangular, the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101 are rectangular rings. The first dam structure 141 is located on the side of the second dam structure 142 close to the display area 10, that is, the first dam structure 141 is located on the inner side of the annular structure enclosed by the second dam structure 142. In this embodiment, the orthographic projections of at least part of the first wiring 1201 on the substrate 1101 are located between the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101.

[0103] In one possible implementation, Figure 5 As shown, the orthographic projection of the first wiring 1201 on the substrate 1101 may be located between the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101. In this case, the orthographic projection of the first wiring 1201 on the substrate 1101 does not overlap with the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101. In another possible implementation, as Figure 6 As shown, the orthographic projection of part of the first wiring 1201 on the substrate 1101 may be located between the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101. In this case, the orthographic projection of the first wiring 1201 on the substrate 1101 overlaps with the orthographic projections of the first dam structure 141 and the second dam structure 142 on the substrate 1101. In this embodiment, the first wiring 1201 is arranged in the first area 201 where the dam structure is located, which can save the wiring space of the first wiring 1201 in the border area 20, and is conducive to narrowing the border.

[0104] For further information, please refer to Figure 7 The display panel 1 also includes a second wiring 1202, the second wiring 1201 is located in the frame area 20, the first wiring 1201 and the second wiring 1202 are insulated from each other, and the second wiring 1202 is electrically connected to the isolation structure 15 distributed in the display area 10, wherein the isolation structure 15 is a conductive isolation structure.

[0105] Please refer to Figure 8 , Figure 8 Example Figure 7 Schematic diagram of a partial film layer structure of the middle display area 10, the display panel 1 includes a light-emitting device 16, in the direction away from the substrate 1101, the light-emitting device 16 includes a first electrode 161, a light-emitting material layer 162 and a second electrode 163 arranged in a stacked manner, at least part of the isolation structure 15 is located between the light-emitting devices 16, specifically, the isolation structure 15 is surrounded by an isolation opening 151 on the substrate 1101, at least part of the light-emitting device 16 can be located in the isolation opening 151, and the second electrode 163 is electrically connected to the isolation structure 15 around the light-emitting device 16.
