That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0026] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a cross-sectional structure of a display panel provided in an embodiment of the present application, Figure 2 A schematic diagram comparing the cross-sectional structures of film layers in different regions of a display panel provided in an embodiment of the present application, Figure 3 A schematic diagram of the detailed structure of the display substrate provided in an embodiment of the present application. The display panel 100 includes a flexible display panel such as an OLED display panel, and the flexible display panel can be bent or folded. The display panel 100 has a flat display area PA and a curved display area WA located on the periphery of the flat display area PA. Both the flat display area PA and the curved display area WA can display images, so that the display panel 100 achieves a higher screen-to-body ratio. The curved display area WA can be located on opposite sides of the flat display area PA to achieve a dual-curved display, or the curved display area WA can also surround the flat display area PA to achieve a four-curved display. Of course, the present application is not limited to this, and the curved display area WA of the present application can also be located on one side of the flat display area PA.

[0027] Specifically, the display panel 100 includes a display substrate 10 and a light shielding layer 20 located in the light emitting direction of the display substrate 10. The display substrate 10 includes a plurality of pixel units 12 arrayed in the planar display area PA and the curved display area WA, and each of the pixel units 12 includes at least three sub-pixels of different colors arranged at intervals. Specifically, the display substrate 10 also includes a driving substrate 11, the pixel unit 12 is located on the driving substrate 11, and the driving substrate 11 is used to drive each sub-pixel of the pixel unit 12 to emit light, so that sub-pixels of different colors emit light of different colors.

[0028] More specifically, the three sub-pixels of different colors include a first color sub-pixel 122, a second color sub-pixel 121, and a third color sub-pixel 123. Optionally, among the three sub-pixels of different colors, one sub-pixel is a blue sub-pixel, another sub-pixel is a red sub-pixel, and the third sub-pixel is a green sub-pixel. For example, the first color sub-pixel 122 is a green sub-pixel, the second color sub-pixel 121 is a red sub-pixel, and the third color sub-pixel 123 is a blue sub-pixel. Then, the driving substrate 11 can drive the first color sub-pixel 122 to emit green light, drive the second color sub-pixel 121 to emit red light, and drive the third color sub-pixel 123 to emit blue light.

[0029] It is understandable that each sub-pixel in the present application is a light-emitting unit, that is, the light-emitting unit is used to characterize the sub-pixel in the present application. The light-emitting unit is usually defined by a pixel definition layer 14 located on the driving substrate 11. Specifically, the light-emitting unit is formed by a light-emitting material printed in a pixel opening 141 of the pixel definition layer 14, and light-emitting materials of different colors form light-emitting units of different colors. In order to protect the light-emitting unit and prevent the light-emitting unit from failing due to water and oxygen intrusion, the display substrate 10 also includes an encapsulation layer 13. The detailed structure of the display substrate 10 will be described in detail later.

[0030] Specifically, the display substrate 10 includes the driving substrate 11, a light-emitting functional layer disposed on the driving substrate 11, and an encapsulation layer 13. The driving substrate 11 includes a substrate 15 and a driving circuit layer disposed on the substrate 15. The material of the substrate 15 includes a flexible material such as polyimide (PI). A flexible display panel 100 can be manufactured using a flexible material as the substrate 15 to achieve a display panel 100 with special properties such as bending and curling. For example, the flexible display panel 100 can be used to manufacture a multi-curved display screen to achieve a higher screen-to-body ratio.

[0031] Optionally, a buffer layer 16 may be provided between the substrate 15 and the driving circuit layer. The material of the buffer layer 16 may include inorganic materials such as silicon oxide (SiOx), silicon nitride (SiNx), silicon oxynitride (SiON), etc. The buffer layer 16 may prevent unwanted impurities or contaminants (such as moisture, oxygen, etc.) from diffusing from the substrate 15 to devices that may be damaged by these impurities or contaminants, while also providing a flat top surface.

[0032] The driving circuit layer includes an active layer 111, a gate insulating layer 112, a gate 113, an interlayer insulating layer 114, a source-drain electrode layer 115, a planarization layer 116, and a pixel electrode 117, which are sequentially stacked on the buffer layer 16. The active layer 111 includes a channel region 1111 and a source region 1112 and a drain region 1113 located on both sides of the channel region 1111, and the gate 113 is arranged corresponding to the channel region 1111.

[0033] The source-drain electrode layer 115 includes a source electrode 1151 and a drain electrode 1152. The source electrode 1151 and the drain electrode 1152 are respectively connected to the source region 1112 and the drain region 1113 of the active layer 111 through via holes of the interlayer insulating layer 114 and the gate insulating layer 112. The planarization layer 116 is disposed on the source-drain electrode layer 115 and the interlayer insulating layer 114 to provide a flat surface for the driving circuit layer.

[0034] The pixel electrode 117 is disposed on the surface of the planarization layer 116 and is connected to the source electrode 1151 or the drain electrode 1152 through a via hole in the planarization layer 116. Figure 3 As shown, the pixel electrode 117 is connected to the drain electrode 1152 .

[0035] The pixel definition layer 14 is disposed on the pixel electrode 117 and the planarization layer 116, and the pixel definition layer 14 is patterned to form a pixel opening 141, and the pixel opening 141 exposes a portion of the pixel electrode 117 to define the setting area of ​​each sub-pixel, wherein the area corresponding to the pixel opening 141 is also the light emitting area of ​​the sub-pixel, and the pixel opening 141 is disposed corresponding to the opening of the light shielding layer 20. It should be noted that the driving circuit layer structure of the present application is not limited to that shown in this embodiment, and the driving circuit layer of the present application may also include more or fewer film layers, and the positional relationship of each film layer is also not limited to that shown in this embodiment, for example, the gate 113 may also be located below the active layer 111 to form a bottom gate structure.

[0036] The light-emitting functional layer is arranged on the driving circuit layer, and the light-emitting functional layer includes each of the sub-pixels for emitting light and a cathode located on the sub-pixel. Each of the sub-pixels emits light under the joint action of the pixel electrode 117 and the cathode.

[0037] The encapsulation layer 13 is located between the cathode and the light shielding layer 20. Specifically, the encapsulation layer 13 covers the cathode. Optionally, the encapsulation layer 13 may be a thin film encapsulation, for example, the encapsulation layer 13 may be a laminated structure formed by sequentially stacking three thin films of a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer, or a laminated structure of more layers.

[0038] The light shielding layer 20 is disposed on the encapsulation layer 13, and the light shielding layer 20 is provided with openings at positions corresponding to the sub-pixels, and the openings are filled with a color filter layer 30, and the color filter layer 30 includes a first color filter 32, a second color filter 31, and a third color filter 33, wherein the first color filter 32, the second color filter 31, and the third color filter 33 correspond to the first color sub-pixel 122, the second color sub-pixel 121, and the third color sub-pixel 123, respectively. Each color filter of the color filter layer 30 can allow light of a corresponding color to pass through, so that the light emitted by each sub-pixel can be emitted from the corresponding opening of the light shielding layer 20, for example, the green light emitted by the first color sub-pixel 122 can pass through the corresponding first color filter 32 and be emitted from the opening of the light shielding layer 20. The shading layer 20 can block external light from entering the display substrate 10, thereby reducing the reflectivity of the display panel 100. By using the shading layer 20 and the color film layer 30 to replace the conventional polarizer, the light transmittance of the display panel 100 can be improved, the power consumption of the display panel 100 can be reduced, and the thickness of the display panel 100 can be reduced, which is more conducive to the flexibility of the display panel 100.

[0039] Optionally, the material of the light shielding layer 20 includes a material with light shielding performance such as a black matrix (BM). The black matrix has excellent light shielding performance and is easy to prepare. The size of the opening of the light shielding layer 20 is greater than or equal to the size of the pixel opening 141 of the pixel definition layer 14, so that the orthographic projection of the opening of the light shielding layer 20 on the drive substrate 11 completely covers the orthographic projection of the pixel opening 141 on the drive substrate 11, which will be more conducive to the light emitted by each sub-pixel passing through the opening of the light shielding layer 20. Among them, the size of the opening of the light shielding layer 20 refers to the opening size of the opening of the light shielding layer 20. When the surface shape of the opening is circular, the opening size can be characterized by the diameter of the opening of the light shielding layer 20. When the surface shape of the opening is square, the opening size can be characterized by the diagonal length of the opening of the light shielding layer 20, and the shape of the opening of the light shielding layer 20 depends on the shape of each sub-pixel. Optionally, the longitudinal cross-sectional shape of the opening includes an inverted trapezoid, etc.

[0040] Further, for at least one sub-pixel of the same color, the size of the opening corresponding to the curved display area WA is greater than the size of the opening corresponding to the flat display area PA. In this embodiment, the first color sub-pixel 122 is preferably taken as an example, and the first color sub-pixel 122 is a green sub-pixel. The first color sub-pixel 122 of the flat display area PA and the first color sub-pixel 122 of the curved display area WA are arranged and sized the same, but the size CD2 of the opening 321 of the light shielding layer 20 corresponding to the first color sub-pixel 122 of the curved display area WA is greater than the size CD1 of the opening 321 of the light shielding layer 20 corresponding to the first color sub-pixel 122 of the flat display area PA, so that the brightness of the curved display area WA can be improved.

[0041] Furthermore, the difference between the size CD2 of the opening 321 of the shading layer 20 corresponding to the first color sub-pixel 122 of the curved display area WA and the size CD1 of the opening 321 of the shading layer 20 corresponding to the first color sub-pixel 122 of the flat display area PA is less than 3 microns, so that the size difference of the opening of the shading layer 20 of the two display areas is controlled within an appropriate range, so as to better improve the brightness of the curved display area WA.

[0042] The following will illustrate the effect of the differentiated design of the openings of the light shielding layer 20 in the curved display area WA and the flat display area PA through simulation:

[0043] Please refer to Figures 1 to 4 , Figure 4 A schematic diagram of the brightness attenuation of the sub-pixels in the curved display area at a 30-degree viewing angle as the size of the shading layer opening changes is provided for the embodiment of the present application. For the convenience of comparison and verification, this embodiment takes the size of the shading layer 20 opening being equal to the size of the pixel opening 141 of the pixel definition layer 14 as an example. In the curved display area WA, the size of the shading layer 20 opening corresponding to each sub-pixel exceeding the size of the corresponding pixel opening 141 of the pixel definition layer 14 can be used to characterize the size of the shading layer 20 opening corresponding to the sub-pixel in the curved display area WA exceeding the size of the shading layer 20 opening corresponding to the sub-pixel in the flat display area PA. Figure 4 The horizontal axis represents the size change of the opening of the light shading layer 20 corresponding to the sub-pixel of the curved display area WA. For example, "0" in the horizontal axis represents that the size of the opening of the light shading layer 20 is equal to the size of the pixel opening 141 of the pixel definition layer 14, and "3" in the horizontal axis represents that the size of the opening of the light shading layer 20 is 3 microns larger than the size of the pixel opening 141 of the pixel definition layer 14. Figure 4 The vertical axis in represents the percentage of brightness attenuation of each sub-pixel. Figure 4Curve A in the figure shows the change trend of the brightness attenuation of the first color sub-pixel 122 as the size of the corresponding opening of the light shielding layer 20 increases, curve B shows the change trend of the brightness attenuation of the second color sub-pixel 121 as the size of the corresponding opening of the light shielding layer 20 increases, and curve C shows the change trend of the brightness attenuation of the third color sub-pixel 123 as the size of the corresponding opening of the light shielding layer 20 increases. The first color sub-pixel 122 is a green sub-pixel, the second color sub-pixel 121 is a red sub-pixel, and the third color sub-pixel 123 is a blue sub-pixel.

[0044] from Figure 4 It can be clearly seen that at a viewing angle of 30 degrees, the brightness attenuation of the first color sub-pixel 122, the second color sub-pixel 121, and the third color sub-pixel 123 of the curved display area WA all decreases as the size of the corresponding light shielding layer 20 opening increases, that is, as the size of the light shielding layer 20 opening increases, the brightness attenuation ratio of each sub-pixel decreases, so that the brightness of the corresponding sub-pixel increases, thereby improving the brightness of the curved display area WA. Among them, the brightness attenuation of the first color sub-pixel 122 decreases most obviously as the size of the corresponding light shielding layer 20 opening increases, so in this embodiment, the light shielding layer 20 opening corresponding to the first color sub-pixel 122 is preferably designed differently.

[0045] In one embodiment, please refer to Figures 1 to 5 , Figure 5 Another schematic diagram for comparing the cross-sectional structures of different regions of the display panel provided in the embodiment of the present application is provided. Different from the above embodiment, the size CD2 of the opening 321 corresponding to the first color sub-pixel 122 of the curved display area WA is larger than the size CD1 of the opening 321 corresponding to the first color sub-pixel 122 of the flat display area PA, and the size CD4 of the opening 311 corresponding to the second color sub-pixel 121 of the curved display area WA is larger than the size CD3 of the opening 311 corresponding to the second color sub-pixel 121 of the flat display area PA. By differentially designing the openings of the light shielding layer 20 corresponding to the two color sub-pixels of the curved display area WA, the brightness of the curved display area WA can be further improved.

[0046] Furthermore, the difference between the size CD4 of the opening 311 of the light shielding layer 20 corresponding to the second color sub-pixel 121 of the curved display area WA and the size CD3 of the opening 311 of the light shielding layer 20 corresponding to the second color sub-pixel 121 of the flat display area PA is less than 3 microns, so that the size difference of the opening of the light shielding layer 20 of the two display areas is controlled within a suitable range, so as to improve the brightness of the curved display area WA. For other descriptions, please refer to the above embodiment, which will not be repeated here.

[0047] In another embodiment, the third color sub-pixel 123 of the curved display area WA may be designed differently, so that the size of the opening corresponding to the third color sub-pixel 123 of the curved display area WA is larger than the size of the opening corresponding to the third color sub-pixel 123 of the flat display area PA, and the difference between the size of the opening of the light shielding layer 20 corresponding to the third color sub-pixel 123 of the curved display area WA and the size of the opening of the light shielding layer 20 corresponding to the third color sub-pixel 123 of the flat display area PA is less than 3 microns, so that the brightness of the curved display area WA can be better improved. For other descriptions, please refer to the above embodiment, which will not be repeated here.

[0048] Based on the same inventive concept, an embodiment of the present application further provides an electronic device, which includes a display panel 100 of one of the above embodiments. The electronic device may be a mobile phone, a tablet, a television, a wearable electronic device, etc.
