Abstract: A projection system wherein two or more separate display sources, such as high brightness sources, or active matrix liquid crystal display (AMLCD) or other flat panel displays are used to write information directly onto a display screen, or onto a photoactivated reflective light valve for projection onto the display screen. Sequential imaging apparatus is used to alternately generate first and second images for display. For example, such images are coupled to the photoactivated reflective light valve and an illumination source is employed to illuminate the light valve and project a composite image onto the display screen. The flat panel displays may be transmissive, reflective, or self-emissive with the use of an optical shutter. A writing illumination source is used for non-self-emissive flat panel displays. Using high brightness display sources, the images may be directly written onto the display screen without the use of the reflective photoactivated light valve and the illumination source.
