Abstract

The invention relates to a diffraction-suppressing optical member, comprising a sheet-like main body, wherein the sheet-like main body comprises a first region arranged periodically, a substantially strip-shaped second region disposed around the first region, and a transition region positioned on the edge of the second region; the transition region extends towards the first region from the edge position of the second region in the normal direction of the edge; and the first region is a light-transmitting region, the second region at least comprises a light-proof region at the edge position, and the transmittance of the transition region changes in the extending direction of the transition region. The invention further relates to a diffraction-suppressing display screen and a diffraction-suppressing photographic device. According to the diffraction-suppressing optical member, the diffraction-suppressing display screen and the diffraction-suppressing photographic device, diffraction generated by the periodic structure of pixel units in an under-screen image pickup device can be suppressed, so that the imaging quality is improved.

Description

technical field [0001] The present invention relates to a diffraction-suppressing optical component, and more particularly, to a diffraction-suppressing optical component for eliminating the diffraction phenomenon of a display screen or an imaging device. The invention also relates to display screens and camera devices comprising diffraction-suppressing optics. Background technique [0002] Taking pictures and displaying is one of the essential functions of smartphones, and the front camera of the mobile phone is very important. It can not only meet the needs of Selfie, but also has great uses in face recognition and content interaction. Front cameras are indispensable in mobile phones. [0003] With the improvement of the functionality of smartphones, large-screen mobile phones are more in line with market trends, but because the screen cannot be expanded infinitely, the demand for mobile phones with high screen-to-body ratio is also relatively strong, and full-screen mobil...
