ABSTRACT:
A frame-sequential color video system and color-selective filters for use in the same. The color-selective filters of the invention have fast response, and can be switched between the three primary colors of red, green, and blue. Switching between the three primary colors is achieved by selective absorption, or by selective interference, which is controlled by the switching of specific device combinations. A frame-sequential color display system is achieved by combining such a color-selective filter with a fast-switching black and white video display, which can be either emissive or reflective. A frame-sequential color camera system is achieved by combining such a color-selective filter with a fast-responding black and white video camera.
