Abstract

The invention discloses a projection screen and a projection device, relates to the technical field of projection display, and is used for solving the problem of poor ambient light resistance of a projection screen in the prior art. The projection screen comprises a surface layer, a polaroid layer, a Fresnel lens layer and a reflecting layer which are stacked. The polaroid layer is configured to transmit linearly polarized light in a preset polarization direction. The projection screen is used for displaying images projected by the projector.

Description

technical field [0001] The present application relates to the technical field of projection display, in particular to a projection screen and a projection device. Background technique [0002] In the field of projection display technology, especially in the field of ultra-short-focus laser projection display, in order to achieve better brightness and display effect, projectors are generally used with projection screens with Fresnel microstructures. [0003] refer to figure 1 A projection screen with a Fresnel microstructure generally includes a stacked surface layer 101 , a first substrate layer 102 , a colored diffusion layer 103 , a second substrate layer 104 , a Fresnel lens layer 105 and a reflective layer 106 . The surface layer 101 is used to protect the projection screen. Diffusion particles 107 are distributed in the colored diffusion layer 103 , and the diffusion particles 107 are used to diffuse light entering the projection screen in different directions. At th...
