Abstract

The invention discloses a diffraction suppression optical component and a diffraction suppression display screen. A first area and a second area are formed, and the first area is basically matched with a preset pattern of a transparent electrode of the display screen; and there is predetermined phase difference between first phase change introduced by the first region to light transmitted therethrough and second phase change introduced by the second region to light transmitted therethrough to compensate for phase change introduced by transparent electrode of transparent display screen to light transmitted therethrough to suppress a diffraction effect caused bythe periodicarrangement of the transparent electrode.

Description

technical field [0001] The present invention relates generally to display screen technology, and more particularly to diffraction suppressed display screens and diffraction suppressed optics useful for transparent displays. Background technique [0002] The current development of transparent display screens enables the application of various optical technologies integrated under the screen, including, for example, under-screen cameras, under-screen fingerprint recognition, and under-screen face recognition modules. The application of these off-screen technologies in turn puts forward higher requirements for transparent displays, one of which is to reduce the diffraction effect of transparent displays. Specifically, the periodically arranged structures in the display screen will form a starburst effect due to the diffraction effect under light irradiation, thereby affecting the quality of imaging and / or projected light field [0003] Therefore, it is urgent to develop new di...
