Abstract:
1. A color Liquid Crystal Display (LCD) device for displaying a temporally-integrated color image comprising a sequence of at least four non-white primary color images, the device comprising: an array of Liquid Crystal (LC) elements; driving circuitry adapted to receive an input corresponding to each of said at least four primary color images and to selectively activate the LC elements of said LC array to produce attenuation patterns corresponding to gray-level representations of each of said at least four primary color images, respectively; and an illumination system adapted to sequentially back-illuminate said LC array with light of at least four different primary colors corresponding to the colors of said at least four primary color images, wherein said illumination system comprises: wherein said driving circuitry and said illumination system are synchronized such that each said attenuation pattern is illuminated with light of the primary color corresponding to the respective primary color image, thereby producing a temporally-integrated image comprising the at least four primary color images, wherein the light produced by the LEDs to back-illuminate the LC array corresponds to the primary colors displayed to produce the temporally-integrated image.
