ABSTRACT:
A digital video system including a light source and a spatial light modulator system. Varying intensities of light to achieve gray shades either with a monochrome system or within each color can be accomplished in several ways. The intensity of the light source itself can be modulated to provide variation, the spatial light modulator elements can have their states in which light is directed to a surface to form a pixel modulated, or both.
