Abstract:
1. A projection screen, comprising: a lenticular layer including rear and front surfaces, said front surface being formed with a plurality of convex microstructures; a reflecting layer formed on said front surface of said lenticular layer and having a plurality of convex surfaces in conformity to surfaces of said convex microstructures; a diffusion layer disposed on said reflecting layer oppositely of said lenticular layer, and including a plurality of black nanoparticles dispersed therein; a lenticular substrate; a light-transmissive substrate; an adhesive layer, said rear surface of said lenticular layer being bonded to said lenticular substrate, said adhesive layer being disposed between said light-transmissive substrate and said reflecting layer to adhere said light-transmissive substrate to said reflecting layer, said diffusion layer being formed on said light-transmissive substrate and opposite to said adhesive layer; a protective substrate; a non-transmissive coating formed on said protective substrate; and another adhesive layer disposed between said non-transmissive coating and said lenticular substrate to adhere said non-transmissive coating to said lenticular substrate.
