Abstract

The invention provides a projection screen and a projection system, which relate to the technical field of projection. Wherein the projection screen comprises a substrate layer; An imaging layer formed on one side of the substrate layer; A light-reflecting film lay is formed on a side of that image layer remote from the substrate layer. The reflective film layer includes a first film layer and a second film layer having a different refractive index from the first film layer so that the reflective film layer is capable of reflecting light of red, green, and blue colors and absorbing light of other colors than red, green, and blue colors. With the above-mentioned setting, the problem that the imaging effect of the existing projection screen is poor can be overcome.

Description

technical field [0001] The present invention relates to the technical field of projection, in particular to a projection screen and a projection system. Background technique [0002] With the continuous development of screen display technology, projection has been widely used as a simple and convenient display method, for example, family entertainment or office needs. Among them, when displaying by projection, an indispensable device is a projection screen. Moreover, the imaging layer plays an important role as a key structure of imaging display in the projection screen. [0003] The inventors found that, in the existing projection screen, the light beam incident on the imaging layer includes not only the light beam output by the projector, but also the light beam emitted by other light sources or natural light in the environment where the projection screen is located. Wherein, the mixing of the light beam or natural light with the light beam output by the projector will l...
