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 design method of a phase type diffraction suppression optical component for a transparent display screen. The method comprises the following steps: acquiring light field complex amplitude distribution of a plane wave on a plane which is separated from the screen by a distance d after the plane wave penetrates through the transparent display screen, and designing a diffraction suppression optical component to make the diffraction suppression optical component have a transmittance function and meet the condition that C is a constant. The invention also discloses the diffraction suppression optical component and an under-screen camera device having the same. According to the invention, the phase type diffraction suppression optical component suppresses the diffraction effect in the under-screen device by providing phase modulation, and improves the under-screen imaging quality.

Description

technical field [0001] The present invention generally relates to under-screen imaging technology, and in particular to a design method of a diffraction-suppressing optical component that can be used to improve the imaging quality of under-screen imaging, a diffraction-suppressing display screen, and an under-screen imaging device. 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...
