Problems solved by technology

However, due to the existence of the display screen, it has a greater impact on the shooting effect of the camera under the screen.
In particular, the periodically arranged unit pixels will form a starburst effect due to the diffraction effect under strong light irradiation, thus affecting the imaging quality

Abstract

The present application discloses a diffraction-suppressing optical component, which is formed as a sheet-like member including first regions arranged periodically in two dimensions and second regions arranged substantially in the shape of stripes around the first regions. , the first region is a light-transmitting region, wherein the second region has a random dislocation in a transverse direction perpendicular to the extending direction by a plurality of unit patterns arranged along the extending direction of the stripe shape and the second region is opaque at least on its two side edge portions. The application also discloses a diffraction-suppressing display screen and an under-screen camera device having the above-mentioned diffraction-suppressing optical component or a corresponding structure. According to the present invention, the diffraction caused by the periodic structure of the pixel unit in the under-screen imaging device can be suppressed, and the imaging quality can be improved.

Description

technical field [0001] The present invention generally relates to under-screen imaging technology, and in particular to a diffraction-suppressing optical component, a diffraction-suppressing display screen, and an under-screen imaging device that can be used to improve the imaging quality of under-screen imaging. Background technique [0002] Taking photos and displaying has become an essential function of smart phones, and the front camera of the smart phone is even more important. Because the front camera can not only meet the needs of selfies, but also has great uses in face recognition and content interaction. Therefore, front cameras have become indispensable in mobile phones. [0003] At the same time, with the improvement of the functionality of smart phones, large-screen mobile phones are more in line with market trends. Since the screen cannot be expanded indefinitely, the demand for mobile phones with high screen ratio is also relatively strong, and the full scre...
