ABSTRACT:
A screen of a projector having a substrate and a plurality of asymmetric optical structures is provided. There is a plurality of light absorbing zones and a plurality of reflective zones alternatively disposed on a surface of the substrate facing the projector. The asymmetric optical structures are disposed on the surface of the substrate and correspond to the reflective zones, respectively. The asymmetric optical structure has a first curved surface and a second curved surface, and the first curved surface protrudes toward the projector for converging an incident light from the projector on the reflective zone, and the second curved surface is disposed at a side of the first curved surface away from the projector for refracting a reflective light from the reflective zones toward the normal direction of the surface of the substrate.
