DEVICE, SYSTEM AND METHOD FOR COLOR DISPLAY
First Claim
1. A color Liquid Crystal Display (LCD) device for displaying a temporally-integrated color image comprising a sequence of at least four 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 an attenuation pattern corresponding to a gray-level representation 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 to sequentially produce said at least four, respective, primary color images,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.

Abstract
A color Liquid Crystal display (LCD) device for displaying a color image using at least four different primary colors, the device including an array of Liquid Crystal (LC) elements, driving circuitry adapted to receive an input corresponding to the color image and to selectively activate the LC elements of the LC array to produce an attenuation pattern corresponding to a gray-level representation of the color image, and an array of color sub-pixel filter elements juxtaposed and in registry with the array of LC elements such that each color sub-pixel filter element is in registry with one of the LC elements, wherein the array of color sub-pixel filter elements comprises at least four types of color sub-pixel filter elements, which transmit light of the at least four primary colors, respectively.
