Abstract

The invention relates to a projection screen, which comprises a substrate, a pattern layer and a matt layer, wherein the pattern layer is attached to a surface of the substrate and has at least one pattern; and the matt layer is positioned between the substrate and the pattern layer or is positioned on the pattern layer and can evenly diffuse light rays projected on the matt layer, so that an image projected to the projection screen by a projector is displayed through the structure.

Description

technical field [0001] The present invention relates to a projection screen, especially a controllable image viewing angle, gain value, color saturation, whiteness, brightness and anti-glare optical rotation, and the use of nanomaterials to enhance its scratch resistance, flame resistance, Projection screen with anti-glare optical rotation, stain resistance, hardness and density. Background technique [0002] With the increasing popularity of projector prices, projectors have become a must-have facility for teaching institutions or companies to perform briefings or to pursue large-size video enjoyment families. [0003] The traditional projection screen is nothing more than a white screen, a black screen and a gray screen (mixture of black + white paint), its gain value is about one, and its viewing angle is very wide about 160-180°. [0004] Generally, in order to increase its gain value, mica powder (Mica) or glass bead powder is coated on the white screen or gray screen,...
