Abstract:
Provided are a light-reflecting microstructure, a projection screen and a projection system. The light-reflecting microstructure includes a transparent structure ( 101 ), the transparent structure ( 101 ) including a light incident surface ( 101 a ), a light-reflecting surface ( 101 b ) and a light-absorption surface ( 101 c ) connecting the light incident surface ( 101 a ) and the light-reflecting surface ( 101 b ); a light-absorption structure ( 102 ) located on the light-absorption surface ( 101 c ); and a reflection layer ( 103 ) located on the light-reflecting surface ( 101 b ). The transparent structure ( 101 ) is configured to refract projected light incident on the light incident surface ( 101 a ) at a preset angle to the reflection layer ( 103 ), and refract stray light incident on the light incident surface ( 101 a ) at another angle to the light-absorption structure ( 102 ). The reflection layer ( 103 ) is configured to reflect the projected light in such a manner that the projected light is emitted at a certain angle from the light incident surface ( 101 a ) after being refracted twice through the transparent structure ( 101 ). The light-absorption structure ( 102 ) is configured to absorb stray light. In this way, not only the projected light projected onto the projection screen can be reflected only to the viewer field by the reflection layer ( 103 ), thereby improving brightness of the projection screen and efficiency of the projection system, but only the problem that the existing light-reflecting microstructure cannot control the stray light can be solved by absorbing the stray light using the light-absorption structure, thereby improving the contrast of the projection screen.

Claim (Index 7):
The light-reflecting microstructure according to  claim 1 , wherein the light-absorption structure is made of a color silicone rubber or a transparent material doped with carbon powder.
