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 projection system comprises a projector and a rollable projection screen, the rollable projection screen comprises a diffusion layer, a Fresnel lens layer and a reflecting layer which are sequentially stacked and arranged, and the diffusion layer comprises a flexible diffusion base material layer and diffusion particles arranged in the flexible diffusion base material layer.

Description

technical field [0001] The invention 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 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] like figure 1 As shown, the above-mentioned projection screen includes a surface layer 101, a coloring layer 102, a diffusion layer 103, a Fresnel lens layer 104 and a reflective layer 105 that are stacked in sequence. The surface layer 101 is used to protect the front projection screen, and the coloring layer 102 includes a The base material layer and the dark dyes arranged in the colored base material layer are used to improve the contrast of the projection screen. The diffusion layer 103 includes the diffusion base material layer...
