[0003] The display area of such a display panel includes an under-screen camera area. When a user needs to take a photo, the sub-pixels in the under-screen camera area stop emitting light, so that external light enters the camera device corresponding to the under-screen camera area to implement functions such as taking photos and videos. When the user does not need to take a photo, the sub-pixels in the under-screen camera area can participate in the display work to display an image.
[0004] However, for a display panel with an under-screen camera function, due to the poor light transmittance of the sub-pixels, the sub-pixels arranged in an array in the under-screen camera area are likely to form a diffraction grating structure, resulting in obvious diffraction phenomena when external light passes through the under-screen camera area, thus interfering with the imaging of the camera device, resulting in poor imaging quality of the camera device and affecting the user experience.

It should be understood that the implementation manners described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0027] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.
[0028] First, the related technologies involved in the present application will be described:
[0029] Currently, when a display panel with an under - screen camera function takes a picture, when external light passes through the under - screen camera area, obvious diffraction phenomena are likely to occur, generating obvious diffraction patterns, which interfere with the imaging of the imaging device, resulting in poor imaging quality of the imaging device. Hereinafter, taking an OLED (Organic Light - Emitting Diode) display panel with an under - screen camera function as an example, the reasons for generating obvious diffraction patterns will be specifically described.
[0030] In the existing OLED display panel, the arrangement of each sub-pixel array in the display area, that is, the arrangement of each sub-pixel has obvious periodicity. Since the anode of the sub-pixel is made of an opaque material, the periodically arranged opaque anodes in the under-screen camera area are likely to form a diffraction grating structure. As a result, when external ambient light passes through the under-screen camera area, obvious diffraction phenomena are likely to occur, and obvious diffraction patterns appear in the under-screen camera area, thereby interfering with the imaging of the imaging device, resulting in poor imaging quality of the imaging device and affecting the user experience.
[0031] The display panel and display device provided by this application aim to solve the above technical problems in the prior art.
[0032] The following will specifically describe the technical solutions of this application and how the technical solutions of this application solve the above technical problems with specific embodiments. It should be noted that the following embodiments can refer to, draw on, or combine with each other. For the same terms, similar features, and similar implementation steps in different embodiments, they will not be described repeatedly.
[0033] The embodiment of this application provides a display panel. The structural schematic diagram of the display panel is as Figure 1 shown, Figure 1 The structural schematic diagram of the first area in the shown display panel is as Figure 2 shown, Figure 2 The schematic diagram of the arrangement relationship between the pixel definition allowable area and the light-emitting area in the shown first area is as Figure 3 shown. The display panel includes: a display area 100, and the display area 100 includes a first area 101 corresponding to an under-screen camera device; the first area 101 includes: a plurality of sub-pixels 10, and the sub-pixel 10 includes a pixel definition allowable area 11, and the pixel definition allowable area 11 includes a light-emitting area 111; in each sub-pixel 10, the position and / or shape of the light-emitting area 111 are randomly distributed within the pixel definition allowable area 11.
[0034] In the display panel provided by the embodiment of this application, by setting the position and / or formation of the light-emitting area 111 in each sub-pixel 10 to be randomly distributed within the pixel definition allowable area 11, the periodicity of the arrangement of the light-emitting areas 111 in the sub-pixels 10 of the first area 101 can be reduced, the probability of each sub-pixel 10 in the first area 101 forming a diffraction grating can be reduced, and further the degree of diffraction phenomenon generated when light passes through the first area 101 can be reduced, the imaging quality of the under-screen camera device can be guaranteed, and the user experience can be guaranteed.
[0035] It should be noted that in the embodiments of the present application, in order to avoid the color mixing problem of adjacent sub-pixels 10 while ensuring the aperture ratio, it is necessary to ensure that the distance between the light-emitting boundaries of any two adjacent sub-pixels 10 is not less than a specific value PDL (Pixel Definition Layer) gap. Through the PDL gap between a sub-pixel 10 and other sub-pixels surrounding the sub-pixel 10, the pixel definition allowable region 11 of the sub-pixel 10 can be determined. That is, the pixel definition allowable region 11 is the region enclosed by the maximum light-emitting boundaries of the other sub-pixels 10 surrounding the sub-pixel 10 in the sub-pixel 10. Optionally, the specific value of the PDL gap depends on device precision, evaporation process, etc.
[0036] In the embodiments of the present application, as Figure 2 and Figure 3 shown, the first region includes a plurality of sub-pixels 10, each sub-pixel 10 includes a pixel definition allowable region 11, and each pixel definition allowable region 11 includes a light-emitting region 111, and the light-emitting region 111 is the part that can emit light in each sub-pixel 10.
[0037] In the embodiments of the present application, as Figure 2 and Figure 3 shown, the position and / or formation of the light-emitting region 111 in each sub-pixel 10 are randomly distributed within the pixel definition allowable region 11, so as to reduce the periodicity of the arrangement of the light-emitting regions 111 in all the sub-pixels 10 in the first region 101.
[0038] In the embodiments of the present application, for the first region 101, the light-emitting region 111 is an opaque region, and other regions are transparent regions, so as to ensure that external light can enter the under-screen camera device through the first region 101.
[0039] Those skilled in the art understand that when light passes through a grating structure with periodicity, obvious diffraction phenomena will occur and obvious diffraction patterns will be formed. In the prior art, the light-emitting regions 111 in the first region 101 are regularly arranged, resulting in obvious diffraction phenomena.
[0040] Next, a specific description will be given of the display panel provided by the embodiments of the present application that can reduce the diffraction intensity of the first region 101. In the embodiments of the present application, by setting the positions of the light-emitting regions 111 in each sub-pixel 10 and / or forming them randomly distributed within the pixel definition allowable region 11, the periodicity of the arrangement of all the light-emitting regions 111 within the first region 101 can be reduced along a plane parallel to the substrate plane. Furthermore, the probability that the light-emitting regions 111 of each sub-pixel 10 within the first region 101 form a diffraction grating can be reduced, the degree of diffraction phenomenon generated when light passes through the first region 101 can be reduced, obvious diffraction images in the pictures and images captured by the under-screen camera device can be avoided, the imaging quality of the under-screen camera device can be guaranteed, and the user experience can be guaranteed.
[0041] It should be noted that in the embodiments of the present application, Figure 2 and Figure 3 are both schematic top-view diagrams, that is, along a plane parallel to the substrate, the positions and / or shapes of the light-emitting regions 111 are randomly distributed within the pixel definition allowable region 11.
[0042] In the embodiments of the present application, for the convenience of intuitively understanding the positional relationship between the pixel definition allowable region 11 and the light-emitting region 111, as Figure 2 and Figure 3 shown, the range of the pixel definition allowable region 11 is represented by a dashed line, and the above-mentioned dashed line does not exist in the actual display panel product.
[0043] Those skilled in the art understand that for the second region 102 that only realizes the display function in the display panel, in order to ensure the aperture ratio and increase the density of the sub-pixels 10 in the second region 102, the pixel design region 11 of the sub-pixels 10 in the second region 102 completely overlaps with the light-emitting region 111, so as to ensure the light-emitting area of each sub-pixel 10 in the second region 102.
[0044] In an embodiment of the present application, the shape of the light-emitting region 111 includes a closed figure enclosed by straight line segments and / or curved line segments.
[0045] In the embodiments of the present application, the shapes of the light-emitting regions 111 are also randomly distributed, that is, the first region 101 includes various different-shaped light-emitting regions 111, so as to further reduce the periodicity of the arrangement of all the light-emitting regions 111 within the first region 101, further reduce the probability that the light-emitting regions 111 of each sub-pixel 10 within the first region 101 form a diffraction grating, thus ensuring the imaging quality of the under-screen camera device and the user experience.
[0046] Optionally, the shape of the light-emitting region 111 can be a polygon such as a triangle, rectangle, square, trapezoid, etc. enclosed by straight line segments, or a circle, ellipse, etc. enclosed by curved line segments, or an image enclosed by straight line segments and curved line segments. In the embodiments of the present application, no specific limitation is made, and those skilled in the art can determine the specific shape of the light-emitting region 111 according to the actual production process and requirements.
[0047] In an embodiment of the present application, the display region 100 includes a second region 102 outside the first region 101; the second region 102 includes a plurality of first sub-pixels (not shown in the figure); the area of the light-emitting region of the first sub-pixel is larger than the area of the light-emitting region 111 of the sub-pixel 10 having the same light-emitting color as the first sub-pixel.
[0048] In the embodiments of the present application, the second region 102 is a region for realizing the normal display function. Optionally, as Figure 1 shown, the second region 102 is disposed around the first region 101.
[0049] In the embodiments of the present application, the area of the light-emitting region of the first sub-pixel is larger than the area of the light-emitting region 111 of the sub-pixel 10 having the same light-emitting color as the first sub-pixel, so as to ensure the light transmittance of the first region 101 and ensure the imaging quality of the under-screen camera device.
[0050] Optionally, taking the sub-pixels of the three primary colors as an example for illustration, the second region 102 includes a first red sub-pixel, a first green sub-pixel, and a first blue sub-pixel, and the first region 101 includes a red sub-pixel 10, a green sub-pixel 10, and a blue sub-pixel 10. Among them, the area of the light-emitting region 111 of the red sub-pixel 10 is smaller than the area of the light-emitting region of the first red sub-pixel, the area of the light-emitting region 111 of the green sub-pixel 10 is smaller than the area of the light-emitting region of the first green sub-pixel, and the area of the light-emitting region 111 of the blue sub-pixel 10 is smaller than the area of the light-emitting region of the first blue sub-pixel.
[0051] Optionally, in the embodiments of the present application, since the light-emitting efficiency of the blue sub-pixel 10 is low, within the first region 101, the area of the light-emitting region 111 of the blue sub-pixel 10 is larger than the area of the light-emitting region 111 of the red sub-pixel 10 and the area of the light-emitting region 111 of the green sub-pixel 10.
[0052] In an embodiment of the present application, the light-emitting region 111 includes a light-emitting structure 1111 having the same shape as the light-emitting region 111.
[0053] In the embodiments of the present application, as Figure 2 and Figure 3As shown, the light-emitting region 111 includes a light-emitting structure 1111 having the same shape as the light-emitting region 111, that is, the edge of the light-emitting structure 1111 completely overlaps with the edge of the light-emitting region 111.
[0054] Optionally, in the embodiments of the present application, the light-emitting structure 1111 is made of an organic light-emitting material, that is, the display panel provided by the embodiments of the present application is an OLED display panel.
[0055] In the embodiments of the present application, the light-emitting region 111 can be formed by defining an opening in the PDL. By depositing an organic light-emitting material in the opening, that is, in the light-emitting region 111, a light-emitting structure 1111 having the same shape as the light-emitting region 111 can be obtained.
[0056] In an embodiment of the present application, an anode 12 is provided on a side of the light-emitting structure 1111 close to the substrate (not shown in the figure); the orthographic projection of the light-emitting structure 1111 on the substrate is located within the orthographic projection of the anode 12 on the substrate.
[0057] In the embodiments of the present application, as Figure 2 shown, the light-emitting structure 1111 is provided on a side of the anode 12 away from the substrate. The orthographic projection of the light-emitting structure 1111 on the substrate is located within the orthographic projection of the anode 12 on the substrate, that is, the anode 12 is slightly larger than the light-emitting structure 1111 to ensure that the anode 12 can drive the light-emitting structure 1111 to emit light and ensure the light-emitting efficiency.
[0058] In the embodiments of the present application, as Figure 2 and Figure 4 shown, since it is necessary to ensure that the orthographic projection of the light-emitting structure 1111 on the substrate is located within the orthographic projection of the anode 12 on the substrate, therefore, a part of the anode 12 will be located in a region outside the pixel definition allowable region 11.
[0059] In an embodiment of the present application, the anode 12 includes an anode body 121 and a connecting portion 122; the anode body 121 is conformable to the light-emitting structure 1111, and the area of the orthographic projection of the anode body 121 on the substrate is larger than the area of the orthographic projection of the light-emitting structure 1111 on the substrate; the extending direction of the connecting portion 122 is randomly distributed in a plane parallel to the substrate.
[0060] In the embodiments of the present application, as Figure 5 shown, the anode 12 includes an anode body 121 and a connecting portion 122. Optionally, the anode body 121 and the connecting portion 122 are prepared simultaneously. Figure 5In order to clearly show the anode body 121 and the connecting part 122, a dividing line is shown between the anode body 121 and the connecting part 122, but such a dividing line does not actually exist in the display panel product. In the embodiment of the present application, the connecting part 122 is used to be electrically connected to the driving thin-film transistor disposed in the substrate, so as to control the light emission and extinction of the light-emitting structure 1111.
[0061] In the embodiment of the present application, the anode body 121 conforms to the shape of the light-emitting structure 1111, and the area of the orthographic projection of the anode body 121 on the substrate is larger than the area of the orthographic projection of the light-emitting structure 1111 on the substrate, so as to ensure that the anode body 121 can drive the light-emitting structure 1111 to emit light and ensure the light-emitting efficiency.
[0062] In the embodiment of the present application, as Figure 5 shown, the extending direction of the connecting part 122 is randomly distributed in the plane parallel to the substrate. Therefore, in the plane parallel to the substrate, the periodic arrangement of all the connecting parts 122 in the first region 101 can be reduced, and further, the probability that the connecting parts 122 of each sub-pixel 10 in the first region 101 form a diffraction grating can be reduced. The degree of diffraction phenomenon generated by the light passing through the first region 101 can be further reduced, the imaging quality of the under-screen camera device can be further ensured, and the user experience can be guaranteed.
[0063] In the embodiment of the present application, by providing the connecting part 122, the anode body 121 can be reduced to a certain extent, so as to improve the light transmittance of the first region 101.
[0064] It should be noted that in the embodiment of the present application, as Figure 2 and Figure 3 shown, if the anode 12 does not separately provide the connecting part 122 electrically connected to the driving thin-film transistor, then a part for electrically connecting to the driving thin-film transistor needs to be reserved in the anode 12.
[0065] In an embodiment of the present application, in each sub-pixel 10, the geometric center of the light-emitting structure 1111 coincides with the geometric center of the anode 12.
[0066] In the embodiment of the present application, as Figure 2 and Figure 6 shown, in all the sub-pixels 10 in the first region 101, the geometric center of the light-emitting structure 1111 of each sub-pixel 10 coincides with the geometric center of the anode 12. Thus, during the light emission process of the sub-pixel 10, in this sub-pixel 10, the geometric center of the light-emitting structure 1111, the geometric center of the anode 12, and the light-emitting brightness center of this sub-pixel 10 coincide, which is convenient for determining the position of the light-emitting brightness center of the subsequent prepared sub-pixel 10 by controlling the positions of the geometric centers in the light-emitting structure 1111 and the anode 12.
[0067] It should be noted that in the embodiments of the present application, for the regularly shaped light-emitting structure 1111 and the anode 12, the geometric center overlaps with the light-emitting brightness center of the sub-pixel 10 obtained in subsequent preparation. For the irregularly shaped light-emitting structure 1111 and the anode 12, the geometric center does not necessarily overlap with the light-emitting brightness center of the sub-pixel 10 obtained in subsequent preparation, and those skilled in the art need to confirm according to the shapes of the actually prepared light-emitting structure 1111 and the anode 12.
[0068] Optionally, in all the sub-pixels 10 within the first region 101, the geometric center of the light-emitting structure 1111 of each sub-pixel 10 overlaps with the geometric center of the anode body 121.
[0069] In an embodiment of the present application, the shape of the light-emitting region 111 includes any one of a circle, an ellipse, a water droplet shape, a rounded rectangle, a rounded triangle, and a rounded trapezoid.
[0070] Optionally, as Figure 2 and Figure 3 shown, the shape of the light-emitting region 111 includes a circle, an ellipse, and a water droplet shape. The circle is the most regular-shaped figure. By arranging the elliptical and water-droplet-shaped light-emitting regions 111 at intervals, the arrangement periodicity of all the light-emitting regions 111 within the first region 101 can be reduced, and further, the probability of the anode 12 corresponding to the light-emitting region 111 within the first region 101 forming a diffraction grating can be reduced, the degree of diffraction phenomenon generated by light passing through the first region 101 can be further reduced, and the imaging quality of the under-screen camera device can be further ensured.
[0071] Optionally, as Figure 6 and Figure 7 shown, the shape of the light-emitting region 111 includes a water droplet shape, a rounded rectangle, a rounded triangle, and a rounded trapezoid. In the embodiments of the present application, by avoiding setting the most regular-shaped circle, the arrangement periodicity of all the light-emitting regions 111 within the first region 101 can be further reduced, and further, the probability of the anode 12 corresponding to the light-emitting region 111 within the first region 101 forming a diffraction grating can be reduced, and the degree of diffraction phenomenon generated by light passing through the first region 101 can be further reduced.
[0072] In an embodiment of the present application, the angle between the line connecting the centers of the light-emitting regions of any two adjacent sub-pixels 10 is an acute angle with respect to the first direction or the second direction; the first direction and the second direction are perpendicular to each other and both are parallel to the substrate.
[0073] In the embodiments of the present application, as Figure 2 and Figure 6As shown, the connecting line between the centers of the light-emitting regions 111 of any two adjacent sub-pixels 10 forms an acute angle with the first direction or the second direction, so that the centers of the light-emitting regions 111 of any three adjacent sub-pixels 10 are not on the same straight line, thereby reducing the periodicity of the arrangement of the light-emitting regions 111 in the sub-pixels 10 of the first region 101, reducing the probability of each sub-pixel 10 in the first region 101 forming a diffraction grating, and further reducing the degree of diffraction phenomenon when light passes through the first region 101, ensuring the imaging quality of the under-screen camera device and ensuring the user experience.
[0074] In an embodiment of the present application, a plurality of sub-pixels 11 form a plurality of first sub-pixel columns and a plurality of second sub-pixel columns; along the first direction, the first sub-pixel columns and the second sub-pixel columns are alternately arranged; the first sub-pixel column includes a plurality of first color sub-pixels 10a and a plurality of third color sub-pixels 10c arranged at intervals along the second direction; the second sub-pixel column includes a plurality of second color sub-pixels 10b; the first direction and the second direction are perpendicular to each other and both are parallel to the substrate.
[0075] In the embodiment of the present application, as Figure 2 and Figure 6 shown, the first region 101 includes a first sub-pixel column and a second sub-pixel column alternately arranged along the first direction, the first sub-pixel column includes a plurality of first color sub-pixels 10a and a plurality of third color sub-pixels 10c arranged at intervals along the second direction, and the second sub-pixel column includes a plurality of second color sub-pixels 10b. Optionally, the light-emitting color of the first color sub-pixel 10a is red, the light-emitting color of the second color sub-pixel 10b is green, and the light-emitting color of the third color sub-pixel 10c is blue.
[0076] In the embodiment of the present application, within the first region 101, in the first sub-pixel column and the second sub-pixel column, the arrangement manner of the first color sub-pixels 10a, the second color sub-pixels 10b, and the third color sub-pixels 10c may include at least one of the following five types.
[0077] First, in the same first sub-pixel column, the connecting line between the centers of the light-emitting regions 111 of the adjacent first color sub-pixel 10a and the third color sub-pixel 10c forms an acute angle with the second direction. Thus, in the same first sub-pixel column, the connecting lines between the centers of the adjacent first color sub-pixel 10a, the third color sub-pixel 10c, and the first color sub-pixel 10a of the light-emitting regions 111 are not on the same straight line, thereby reducing the periodicity of the arrangement of the light-emitting regions 111 in the sub-pixels 10 of the first region 101 and reducing the probability of each sub-pixel 10 in the first region 101 forming a diffraction grating.
[0078] Second, in any two adjacent first sub-pixel columns, the angle between the line connecting the centers of the light-emitting regions 111 of the first color sub-pixels 10a in one first sub-pixel column and the third color sub-pixels 10c adjacent to the other first sub-pixel column and the first direction is an acute angle. Similarly, the periodic arrangement of the light-emitting regions 111 in the sub-pixels 10 of the first region 101 can be reduced, and the probability of each sub-pixel 10 in the first region 101 forming a diffraction grating can be reduced.
