Abstract

The invention discloses a rollable projection screen and a projection system, relates to the technical field of projection screens, and is used for solving the problem that a projection screen in the prior art cannot be rollable. The rollable projection screen comprises a flexible surface layer, flexible base material layers, a Fresnel lens layer and a reflecting layer which are sequentially stacked and arranged. The number of the flexible base material layers is multiple, and in the curling direction of the rollable projection screen, the thickness of the front flexible base material layer is smaller than that of the rear flexible base material layer. The rollable projection screen can be rollable and is very convenient to transport, install and use.

Description

technical field [0001] The present application relates to the technical field of projection screens, in particular to a rollable 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 in the prior art. The above-mentioned projection screen includes a surface layer 101 , a colored layer 102 , a diffusion layer 103 , a Fresnel lens layer 104 and a reflective layer 105 arranged in sequence. The surface layer 101 is used to protect the projection screen. The colored layer 102 includes a colored base layer and a dark dye disposed in the colored base layer for improving the contrast of the projection screen. The diffus...
