Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not in themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
It should be noted that, without conflict, features in embodiments of the present application may be combined with each other.
The inventor finds that if full screen display is to be realized in the process of preparing the display panel, sensing devices such as a camera and the like are required to be arranged below the display screen, a display area provided with the camera is called a secondary screen area, and the rest areas are primary screen areas. The film layer light transmittance of the existing display screen is lower, lighting of a camera can be affected, and photographing effect is affected. If the film layer of the auxiliary screen area is patterned to provide lighting space for the camera, the pixel density of the auxiliary screen area is reduced, and the display effect of the main screen and the auxiliary screen is different, so that the user experience is affected. Therefore, the inventor provides a new display screen for ensuring that the lighting effect of the camera is good and the display effect of the main screen and the auxiliary screen area is not obviously different.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display screen according to an embodiment, and fig. 2 is a schematic sectional structural diagram along AA' direction in the display screen of fig. 1. The display screen 100 comprises a substrate 1, a light-emitting functional layer 2, a buffer layer 3 and a packaging layer 4 which are sequentially stacked, wherein the display screen 100 is divided into a first display area 10 and a second display area 20, and the light transmittance of the buffer layer 3 of the second display area 20 is larger than that of the buffer layer 3 of the first display area 10. The inventor finds that in the process of researching the display screen, light rays emitted by the light-emitting functional layer are emitted through the buffer layer and the packaging layer, and the buffer layer can improve the transmittance of the light rays, so that the light-emitting efficiency of the display screen is improved, and the transmittance of the display screen is influenced by the performance of the buffer layer, so that the light-emitting efficiency is influenced. In this embodiment, by setting the light transmittance of the buffer layer 3 of the second display area 20 to be greater than the light transmittance of the buffer layer 3 of the first display area 10, more ambient light can be irradiated onto the camera through the buffer layer 3 of the second display area 20, and the lighting efficiency of the camera is higher. Meanwhile, the pixel area and the pixel density of the second display area 20 do not need to be adjusted, that is, the pixel area and the pixel density of the second display area 20 can be consistent with the pixel area and the pixel density of the first display area 10, so that the display effects of the second display area 20 and the first display area 10 can be consistent.
In another embodiment of the present invention, the area of the single subpixel of the second display area 20 may be different from the area of the single subpixel of the first display area 10, specifically, the light transmittance of the buffer layer 3 of the second display area 20 is set to be greater than the light transmittance of the buffer layer 3 of the first display area 10, so that the light transmittance of the second display area may be improved, and the light sensing device such as a camera may be facilitated to receive ambient light. Therefore, further, without changing the pixel density (PPI), the area of the single sub-pixel of the second display area 20 may be set smaller than that of the single sub-pixel of the first display area 10, the area of the sub-pixel may be made smaller, and the corresponding substrate, light-emitting functional layer, buffer layer, and packaging layer may be made smaller, so that more space may be avoided for the camera to receive ambient light, and a better lighting effect may be achieved. Further, since the pixel densities of the first display region 10 and the second display region 20 are unchanged, the display effects of the first display region 10 and the second display region 20 are kept uniform, and there is no display difference.
It should be noted that, in the course of the study, the inventor has found that the area ratio of the single subpixel area of the second display area 20 to the single subpixel area of the first display area 10 may be in the range of 1:1 to 1:3, and in this range, the display effects of the first display area 10 and the second display area 20 may be substantially consistent, and no display difference exists.
In another embodiment of the present invention, the display 100 includes a substrate 1, a light emitting functional layer 2, a buffer layer 3, and an encapsulation layer 4 stacked, the display 100 is divided into a first display area 10 and a second display area 20, and the buffer layer 3 of the second display area 20 has a light transmittance greater than that of the buffer layer 3 of the first display area 10. The area of a single subpixel of the second display area 20 is equal to or smaller than the area of a single subpixel of the first display area 10, and the pixel density of the first display area 10 is the same as that of the second display area 20. By setting the light transmittance of the buffer layer 3 of the second display area to be larger, more ambient light can be transmitted through the second display area, and the lighting efficiency of the camera is higher. Meanwhile, the pixel densities of the first display area 10 and the second display area 20 are the same, and it is ensured that the display effects of the first display area 10 and the second display area 20 are substantially the same. Meanwhile, the area of the single subpixel of the second display area 20 may be the same as the area of the single subpixel of the first display area 10, or the area of the single subpixel of the second display area 20 may be equal to or smaller than the area of the single subpixel of the first display area 10. If the area of a single sub-pixel of the second display area 20 is smaller, more avoidance space can be reserved for the camera, lighting of the camera is further facilitated, the light transmission effect of the second display area is better, the display effect of under-screen shooting is improved, and the shooting requirement of consumers is met. If the area of the single sub-pixel of the second display area 20 is equal to that of the single sub-pixel of the first display area 10, the sub-pixels of the first display area 10 and the sub-pixels of the second display area 20 can be prepared in the same process, and the same mask plate is adopted, so that a new mask plate or a new process step is not required to be added, and the preparation is simpler.
In another embodiment of the present invention, the thickness of the buffer layer 3 of the first display area 10 may be different from the thickness of the buffer layer 3 of the second display area 20. The inventor finds that the thickness of the buffer layer can influence the transmittance of light in the process of researching the display screen; the light transmittance of the second display area 20 can be further improved by thinning the thickness of the buffer layer 3 of the second display area 20. The inventor finds through experiments that when the ratio of the thickness of the buffer layer 3 of the first display area 10 to the thickness of the buffer layer 3 of the second display area 20 is in the range of 3:1-1:1, the transmittance of the second display area 20 is the highest, and at this time, the adjustment of the pixels of the second display area 20 is not required, and the display effect of the first display area 10 and the second display area 20 can be ensured to be basically consistent without adjusting the pixel density and the pixel area of the second display area 20.
Further, in another embodiment of the present invention, the thicknesses of the buffer layers corresponding to the sub-pixels of different colors of the second display area 20 are different. The inventor finds that if the blue light in the second display area 20 is attenuated fast in the process of researching the display screen, the thickness of the buffer layer 3 at the position corresponding to the blue sub-pixel in the second display area 20 is reduced, the light transmittance of the blue light can be increased, and color cast caused by the too fast attenuation of the blue light is relieved. For other color sub-pixels, the thickness of the buffer layer corresponding to the sub-pixels with different colors in the second display area 20 is adjusted, so that the problem of visual character deviation can be solved while ensuring higher light transmittance.
In another embodiment of the present invention, the sub-pixels in the first display area 10 include a blue sub-pixel, a red sub-pixel and a green sub-pixel, the sub-pixels in the second display area 20 also include a blue sub-pixel, a red sub-pixel and a green sub-pixel, and the thickness of the buffer layer corresponding to the blue sub-pixel in the second display area 20 is smaller than the thickness of the buffer layer corresponding to the blue sub-pixel in the first display area 10, while the thickness of the buffer layer corresponding to the green sub-pixel in the second display area 20 is equal to the thickness of the buffer layer corresponding to the green sub-pixel in the first display area 10, and the thickness of the buffer layer corresponding to the red sub-pixel in the second display area 20 is equal to the thickness of the buffer layer corresponding to the red sub-pixel in the first display area 10. The inventor finds that blue light decays faster than red light and green light in the process of researching the display screen, and the blue light decays easily to cause poor display effect of the screen along with the increase of the service time of the screen. And blue light decays more rapidly under the large visual angle, and the display effect under the large visual angle is easily influenced. Therefore, the thicknesses of the buffer layers corresponding to the blue sub-pixels in the second display area are reduced, the thicknesses of the buffer layers corresponding to the sub-pixels in other colors in the second display area and the thicknesses of the buffer layers corresponding to the sub-pixels in the first display area are kept consistent, and the display effect in the second display area can be prevented from being influenced by blue light attenuation to a certain extent. It should be noted that, in this embodiment, the display screen is described as including three color sub-pixels, and the present invention is equally applicable to a display screen formed by sub-pixels of multiple colors.
In another embodiment of the present invention, the display screen further includes a first driving unit for driving the first display area 10 to display and a second driving unit (not shown in the figure) for driving the second display area 20 to display. The display screen can also comprise a control device, and the control device can control the first driving unit and the second driving unit to send out driving signals of different display pictures, so that the first display area and the second display area of the display screen display different pictures, namely, split-screen display of the display screen is realized. In addition, the driving signals of the first driving unit and the second driving unit can be adjusted according to the display difference of the first display area and the second display area, so that the display effect of the first display area and the display effect of the second display area are basically consistent.
In another embodiment of the present invention, the material of the buffer layer in the first display area is lithium fluoride, and the material of the buffer layer in the second display area is silicon oxide or silicon oxynitride or a mixture of silicon oxide and silicon oxynitride. The thickness of the buffer layer of the first display region may be set at 50-70nm, and the thickness of the buffer layer of the second display region may be set at 20-60nm.
In another aspect of the present invention, an electronic device is provided, including a housing, a display cover plate, a camera, and a display as described above, where the housing and the display cover plate enclose a receiving space, the display and the camera are disposed in the receiving space, and the camera is disposed on a non-light-emitting side of a second display area of the display.

providing a substrate;
preparing a luminescent functional layer on a substrate;

preparing a buffer layer of a second display area on the light-emitting functional layer;
preparing a packaging layer on the buffer layer;
the light transmittance of the buffer layer of the second display area is larger than that of the buffer layer of the first display area.
It should be noted that if the material of the buffer layer in the first display area is different from the material of the buffer layer in the second display area, taking lithium fluoride as an example, and silicon oxide as the material of the buffer layer in the second display area, the lithium fluoride buffer layer in the first display area can be evaporated by using the first mask, and then the silicon oxide buffer layer in the second display area can be prepared by using the second mask through a Chemical Vapor Deposition (CVD) process. In addition, if the thickness of the buffer layer of the second display area is smaller than that of the buffer layer of the first display area, and the material of the buffer layer of the second display area is the same as that of the buffer layer of the first display area, the buffer layer with the same thickness can be prepared from the first display area and the second display area, and then the part needing to be thinned is etched; or preparing a buffer layer with the same thickness, and then continuously thickening the area needing to be thickened.
