Abstract

The invention discloses a projection screen and a projection system, relates to the technical field of projection screens, and is used for solving the problem that aluminum powder in a reflecting layer in a projection screen in the prior art is easy to fall off. The projection screen comprises a surface layer, a base material layer, a Fresnel lens layer and an aluminum reflecting layer which are sequentially stacked and arranged, and aluminum particles in the aluminum reflecting layer are scaly aluminum powder. The aluminum particles in the aluminum reflecting layer in the projection screen are high in adhesion fastness and not prone to falling off.

Description

technical field [0001] The present application relates to the technical field of projection screens, in particular to a projection screen and a projection system. Background technique [0002] In the field of projection display, especially the field of ultra-short-throw laser projection display, in order to achieve better brightness and display effect, the projector is generally used with a projection screen with Fresnel microstructure. [0003] refer to figure 1 , figure 1 It is a structural schematic diagram of a projection screen with a Fresnel microstructure in the prior art. The projection screen generally includes a substrate layer 101 , a Fresnel lens layer 102 and a reflective layer 103 which are sequentially stacked. The Fresnel lens layer 102 can change the propagation direction of light because of its special structure, but because the Fresnel lens layer 102 is generally transparent or translucent, if no material is added, most of the light will directly pass t...
