Patent ID: 7995019

Claim:
A color Liquid Crystal Display (LCD) device for displaying a color image using at least five different colors, the device comprising: an array of Liquid Crystal (LC) elements; driving circuitry adapted to receive an input corresponding to said color image and to selectively activate the LC elements of said LC array to produce an attenuation pattern corresponding to a gray-level representation of said color image; a back illumination source to generate light; and an array of color sub-pixel filter elements to filter the light generated by said back illumination source, said array of color sub-pixel filter elements being juxtaposed and in registry with said array of LC elements such that each color sub-pixel filter element is in registry with one of said LC elements, wherein said array of color sub-pixel filter elements comprises at least five different colored sub-pixel filter elements, which transmit light of said at least five different colors, respectively, wherein the light transmitted through each of said sub-pixel filter elements is independent of the other sub-pixel filter elements, and wherein the color gamut of the LCD device is wider than the color gamut of a standard RGB display.
