ABSTRACT:
The invention is a multi-color display screen that has built in optical memory for each pixel location. The optical memory is optically read and optically programmed. The screen itself distinguishes between the specific colors from which a full-color (or multi-color) image is constructed and modulates the intensities of the component colors that it directs toward a viewer. The screen provides enhanced image resolution and reduces information bandwidth required to control the display the image.
