ABSTRACT:
A rear projection screen and a method of using the screen in imaging systems is provided in which the screen provides discrete areas which are isolated from one another whereby the light of one discrete area cannot be transmitted to another discrete area, each discrete area being filled with a filler material which diffuses the light passing therethrough so that at the viewing face of the screen each discrete area has a uniform light intensity across its width while neighboring discrete area may have sharply contrasting light intensities.
