Abstract
Disclosed is a light-transmissive material and methods of its manufacture. The light-transmissive material of the invention uses two distinct particles in a diffusive layer to provide increased light transmissive properties. For example, when used as a rear projection screen, the light-transmissive material of the invention exhibits high gain, high contrast, and low scintillation. In another embodiment of the invention, the light-transmissive material includes light channeling contrast enhancement layer.
