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 invention discloses a diffraction suppression optical member. The member is formed into a sheet-shaped piece, the sheet member comprises a first region arranged in a two-dimensional periodic manner and a second region which is arranged around the first region and is approximately in a strip shape, wherein the first region is a light-transmitting region, the second region has a shape generatedby randomly staggering a plurality of unit patterns arranged along the extending direction of the strip shape in a transverse direction perpendicular to the extending direction, and the second regionis light-proof at least on two side edge parts thereof. The invention further discloses a diffraction inhibition display screen with the diffraction inhibition optical member or a corresponding structure and an under-screen camera device. The member is advantaged in that diffraction generated by the periodic structure of the pixel unit in the under-screen camera device can be suppressed, and the imaging quality is 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...
