Detailed implementation manners

[0080] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. The components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0081] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, and does 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 construed as a limitation of the present application.

[0082] In some display panels, in order to reduce the difficulty of the evaporation process of the light-emitting material, an isolation structure is provided on the pixel definition layer between pixel apertures. When the light-emitting material layer and the cathode layer are evaporated as a whole layer, the light-emitting material layer and the cathode layer between adjacent pixel apertures can be disconnected at the position of the isolation structure. Through multiple evaporation and multiple etching processes, corresponding sub-pixel device film layers can be formed in the pixel apertures corresponding to different color sub-pixel devices.

[0083] The above display panel has the problem of low reflectivity. To solve the above technical problems, the related art provides the following two solutions. Solution 1: Increase the anode area of the sub-pixel to enhance the reflectivity; Solution 2: Use a polarizer or other functional film layer with a higher reflectivity to enhance the reflectivity.

[0084] The inventor's research found that in Solution 1, increasing the anode area will compress the layout space of the pixel definition layer between adjacent sub-pixel devices and increase the process difficulty. In Solution 2, using a polarizer or other functional film layer with a higher reflectivity will reduce the light extraction efficiency of self-luminescence. On the premise of ensuring that the light emission intensity of self-luminescence remains unchanged, it is necessary to increase the panel power consumption, which will reduce the service life of the display panel.

[0085] To solve the above problems, the inventor innovatively designs the following technical solution to solve the technical problem of low reflectivity of the display panel with an isolation structure. The specific implementation solution of the present application will be described in detail below with reference to the drawings. It should be noted that the defects existing in the above solutions in the prior art are all the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above technical problems and the solution proposed by the present embodiment below for the above problems should be the contributions made by the inventor to the present application during the invention and creation process, and should not be understood as the technical content known to those skilled in the art.

[0086] Please refer to Figure 1 , Figure 1 FIG. is a schematic diagram of a partial film layer structure of the display panel provided in this embodiment. In this embodiment, the display panel 10 includes an array substrate 110 and an isolation structure 120, and the isolation structure 120 is located on the array substrate 110. At least part of the isolation structure 120 forms a light-concentrating surface 121 that is recessed toward the array substrate on the side away from the array substrate 110.

[0087] The light-concentrating surface 121 can concentrate and reflect the large-angle light incident into the display panel 10 in the direction perpendicular to the array substrate 110, thereby increasing the reflectivity of the display panel 10. When the user uses the display device equipped with the display panel 10, in the off-screen state, clear imaging can be achieved through the reflection of the display panel 10, improving the user experience and being beneficial to the improvement of the product market competitiveness.

[0088] In this embodiment, please refer to Figure 2 and Figure 3 . The isolation structure 120 further encloses an isolation opening 1201 on the array substrate 110. The distance h1 between the light-concentrating surface 121 and the array substrate 110 increases in the direction of the isolation opening 120 from the bottom position of the light-concentrating surface 121. In other words, the opening of the light-concentrating surface 121 faces away from the array substrate 110, and the depth h2 of the opening increases from both sides of the opening towards the bottom of the light-concentrating surface 121. Here, the bottom of the light-concentrating surface 121 refers to the position where the distance value between the light-concentrating surface 121 and the array substrate 110 is the smallest. In the cross-section of the light-concentrating surface 121 along the direction connecting adjacent isolation openings 120, the bottom of the light-concentrating surface 121 can be a point or an edge. Exemplarily, as Figure 3 and Figure 4 show, when the cross-sectional shape of the light-concentrating surface 121 along the direction connecting adjacent isolation openings 120 is arc-shaped and V-shaped, the bottom of the light-concentrating surface 121 can be a point (point A in the figure); as Figure 5 shows, when the cross-sectional shape of the light-concentrating surface 121 along the direction connecting adjacent isolation openings 120 is inverted trapezoidal, the bottom of the light-concentrating surface 121 can be an edge (A1A2 in the figure).

[0089] In this embodiment, optionally, the distance h1 between the light-concentrating surface 121 and the array substrate 110 gradually increases in the direction of the isolation opening 120 from the bottom position of the light-concentrating surface 121, the depth h2 of the opening gradually increases from both sides of the opening towards the bottom of the light-concentrating surface 121, and the cross-sectional shape of the light-concentrating surface 121 along the direction connecting adjacent isolation openings 120 is arc-shaped. It should be noted that the arc here can be a smooth arc or a non-smooth arc (for example, as Figure 6 shows, it is an arc contour composed of many broken lines). For the convenience of subsequent technical solution description, the subsequent description of the solution of this embodiment will be made with the attached drawings in which the cross-sectional shape of the light-concentrating surface 121 along the direction connecting adjacent isolation openings 120 is a smooth arc.

[0090] Please refer to Figure 7 and Figure 8 . Figure 7 Illustrates the reflection light path diagram of ambient light on the side of the isolation structure 120 away from the array substrate 110 in the related art, Figure 8 Illustrates the reflection light path diagram of external ambient light on the side of the isolation structure 120 away from the array substrate 110 in this embodiment. From Figure 7 and Figure 8 , it can be seen that the light-concentrating surface 121 in this embodiment can converge the external ambient light obliquely incident at a large angle into the display panel towards the forward light-emitting direction of the display panel after reflection by it, that is, it can increase the light intensity of the external ambient light emitted forward after reflection by the light-concentrating surface 121, so as to achieve the purpose of increasing the reflectivity of the display panel 20.

[0091] Further, please refer to Figure 9 , the isolation structure 120 includes a stacked isolation portion 1203 and a blocking portion 1204. The orthographic projection of the isolation portion 1203 on the array substrate 110 is located within the orthographic projection of the blocking portion 1204 on the array substrate 110. Optionally, in this embodiment, the isolation structure 120 may further include an isolation substrate 1202. The isolation substrate 1202, the isolation portion 1203, and the blocking portion 1204 are stacked in sequence. The orthographic projection of the isolation portion 1203 on the array substrate 110 is located within the orthographic projection of the isolation substrate 1202 on the array substrate 110, and the orthographic projection of the isolation substrate 1202 on the array substrate 110 is located within the orthographic projection of the blocking portion 1204 on the array substrate 110. That is, in the direction towards the isolation opening 1201, the isolation substrate 1202 and the blocking portion 1204 respectively protrude relative to the isolation portion 1203.

[0092] In this embodiment, please refer to Figure 2 again. The extending direction of the light collecting surface 121 is the same as the extending direction of the isolation structure 120, that is, the light collecting surface 121 is arranged along the extending direction of the isolation structure 120. The orthographic projection of the light collecting surface 121 on the array substrate 110 is located within the orthographic projection of the isolation structure 120 on the array substrate 110.

[0093] Please refer to Figure 9 again. In this embodiment, the light collecting surface 121 is formed by the surface on the side of the blocking portion 1204 away from the array substrate 110. That is, there is a concave surface on the side of the blocking portion 1204 away from the array substrate 110 that is recessed towards the array substrate 110, and the light collecting surface 121 is formed by this concave surface. With such a design, by adjusting the original film layer structure, the reflectivity can be improved, and the process can be simplified without adding new film layers.

[0094] In order to improve the reflectivity of the display panel 10, the blocking portion 1204 can be made of a material with a relatively high light reflectivity. Exemplarily, the blocking portion 1204 can be made of a metal material with a relatively high light reflectivity. For example, the blocking portion 1204 can be made of titanium metal.

[0095] Further, please refer to Figure 9 again. The side of the isolation portion 1203 away from the array substrate 110 includes a first concave surface 12031 that is recessed towards the array substrate 110. The area of the blocking portion 1204 corresponding to the first concave surface 12031 is recessed towards the array substrate 110 to form the light collecting surface 121. The blocking portion 1204 is distributed in a undulating manner along the surface of the isolation portion 1203. The first concave surface 12031 can be formed by etching the isolation portion 1203. In this embodiment, the orthographic projection of the light collecting surface 121 on the array substrate 110 is located within the orthographic projection of the first concave surface 12031 on the array substrate 110.

[0096] Further, please refer to Figure 10 , the display panel 10 further includes a pixel defining layer 130 and a sub-pixel device 140. The pixel defining layer 130 is located on one side of the array substrate 110, and the isolation structure 120 is located on the side of the pixel defining layer 130 away from the array substrate 110. The pixel defining layer 130 includes a pixel opening 1301, and the pixel opening 1301 communicates with the isolation opening 1201. The sub-pixel device 140 is disposed in the pixel opening 1301.

[0097] The side of the pixel defining layer 130 away from the array substrate 110 includes a second concave surface 1302 that is recessed in the direction of the array substrate 110. The film layers forming the isolation structure 120 are distributed in a undulating manner on the pixel defining layer 130, that is, the orthographic projection of the first concave surface 12031 on the array substrate 110 is located within the orthographic projection of the second concave surface 1302 on the array substrate 110. In this embodiment, the second concave surface 1302 can be formed by etching the pixel defining layer 130.

[0098] The sub-pixel device 140 includes a first electrode 1401, a light-emitting material layer 1402, and a second electrode 1403 that are stacked. The first electrode 1401 is distributed at intervals on one side of the array substrate 110. Exemplarily, the first electrode 1401 is distributed at the position of the array substrate 110 corresponding to the isolation opening 1201, and the pixel opening 1301 exposes the first electrode 1401. The light-emitting material layer 1402 extends from the pixel opening 1301 to the side of the pixel defining layer 130 away from the array substrate 110, and the second electrode 1403 extends from within the pixel opening 1301 to the side of the pixel defining layer 130 away from the array substrate 110 and overlaps with the isolation substrate 1202 around the isolation opening 1201. In this embodiment, the first electrode 1401 can be the anode of the sub-pixel device 140, and the second electrode 1403 can be the cathode of the sub-pixel device 140.

[0099] Further, please refer to Figure 11 , the display panel 10 may further include a planarization layer 150. The planarization layer 150 is located between the array substrate 110 and the pixel defining layer 130. In this embodiment, the side of the planarization layer 150 away from the array substrate 110 includes a third concave surface 1501 that is recessed in the direction of the array substrate 110. The film layers of the pixel defining layer 130 and the isolation structure 120 are distributed in a undulating manner on the planarization layer 150, that is, in the area where the third concave surface 1501 is located, the pixel defining layer 130 forms the second concave surface 1302, and the isolation structure 120 forms a light condensing surface 121. Among them, the third concave surface 1501 can be obtained by etching the planarization layer 150, and the orthographic projection of the second concave surface 1302 on the array substrate 110 is located within the orthographic projection of the third concave surface 1501 on the array substrate 110.

[0100] Further, please refer toFigure 12 On each isolation structure 120, a plurality of light-concentrating surfaces 121 may be distributed. In the direction of the connection line between two adjacent isolation openings 1201, the plurality of light-concentrating surfaces 121 are spaced apart. Preferably, the plurality of light-concentrating surfaces 121 distributed on each isolation structure 120 are parallel to each other, and in the direction of the connection line between two adjacent isolation openings 1201, the plurality of light-concentrating surfaces 121 are equally spaced. In this embodiment, in order to make the display panel reflect light uniformly, it is preferred that the sizes of the plurality of light-concentrating surfaces 121 are the same.

[0101] Further, please refer to Figure 13 The display panel 10 provided in this embodiment further includes a packaging layer. The packaging layer includes a plurality of packaging units 161. Each packaging unit 161 is used to package a sub-pixel device 130 in a corresponding isolation opening 1201. The adjacent packaging units 161 are disconnected on the side of the isolation structure 120 away from the array substrate 110.

[0102] Based on the same inventive concept, this embodiment also provides a manufacturing method for manufacturing the above display panel. Please refer to Figure 14 and Figure 15 Figure 14 which exemplifies the schematic flow chart of the manufacturing method of the display panel provided in this embodiment, Figure 15 exemplifies Figure 14 the corresponding process flow chart. The following will introduce the above manufacturing method in detail with reference to Figure 14 and Figure 15

[0103] Step S10: Provide an array substrate 110.

[0104] The array substrate 110 includes a plurality of metal film layers and a plurality of non-metal film layers. In the array substrate 110, a pixel driving circuit for driving the sub-pixel device to emit light can be formed through the wiring design of the metal film layer.

[0105] Step S20: Fabricate an isolation structure 120 on the array substrate 110, and at least partially form a light-concentrating surface 121 recessed toward the array substrate on the side of the isolation structure 120 away from the array substrate 110.

[0106] In an implementation manner of this embodiment, the isolation structure 120 includes a stacked isolation substrate 1202, an isolation portion 1203, and a blocking portion 1204. Please refer to Figure 16 and Figure 17 Step S20 can be implemented in the following manner.

[0107] Step S2011: Successively fabricate an isolation base layer 20 and an isolation layer 30 on the array substrate 110.
