Screen and projection system

Abstract

A screen capable of reflecting projected light from a projector to a viewer's field of view, at least comprising a surface diffusion layer (14), a transmission light-absorbing layer (13) and a projection reflective layer (12) which are stacked sequentially from the incident side of the projected light. The projection reflective layer (12) selectively reflects the projected light. The transmission light-absorbing layer (13) comprises light-absorbing material particles, and the distribution of the light-absorbing material particles in the transmission light-absorbing layer (13) is set according to the distribution of the Fresnel loss of the projected light on the surface of the screen, such that the light transmittance of the transmission light-absorbing layer (13) is higher in the region where the Fresnel loss is larger. Further disclosed is a projection system comprising the screen. The screen and the projection system have high contrast and high brightness uniformity.
