Title:
DISPLAY SCREEN, TERMINAL DEVICE, AND UNDER-SCREEN CAMERA IMAGING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/232378
Kind Code:
A1
Abstract:
The present disclosure relates to a display screen, a terminal device, and an under-screen camera imaging control method. The display screen comprises: a transparent substrate, a light-emitting material being formed at the upper surface of the transparent substrate; and a diffraction compensation pattern, wherein the diffraction compensation pattern is formed below the transparent substrate, and is used for compensating for a diffraction image which is formed by incident light after same passes through the light-emitting material. By means of forming the diffraction compensation pattern below the transparent substrate where the light-emitting material is formed, a diffraction image which is formed by incident light after passing through the light-emitting material can be compensated for, such that the influence of the diffraction image on imaging of an under-screen camera is eliminated or reduced, and the imaging quality of the under-screen camera is improved. Moreover, the pattern is directly generated on an original element of a display screen, the distances between the pattern and a screen trace and between the pattern and a light-emitting material layer are relatively controllable, and no subsequent assembly is required, thereby greatly reducing the additional assembly and alignment risks that may be caused by a compensation solution, and improving the stability and yield of a system.
