Title:
SCREEN AND PREPARATION METHOD THEREFOR, AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/147577
Kind Code:
A1
Abstract:
Disclosed are a screen (100) and a preparation method therefor, and a projection system. The screen (100) comprises a substrate (110); a surface diffusion layer (120) arranged on the surface of one side of the substrate (110); a Fresnel layer (130) arranged on the surface of the side of the substrate (110) that is away from the surface diffusion layer (120); and a projection reflection layer (140) arranged on the surface of the side of the Fresnel layer (130) that is away from the substrate (110), wherein the materials of the projection reflection layer (140) include a reflecting material and an absorbing material, and/or the Fresnel layer (130) comprises a plurality of microstructure units (131), and the plurality of microstructure units (131) are sequentially arranged outwards based on the same center of a circle. The gain and the ambient light contrast resistance of the screen (100) can thus be improved.
