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.

Dependent claims

A color display device for displaying an n-primary image, wherein n is greater than or equal to six, comprising an array of color sub-pixel elements including color sub-pixel elements of each of at least six different primary colors, including at least a first set of primary colors and a second set of primary colors, arranged in a periodically repeating arrangement comprising at least one color sub-pixel element of each of said at least six different primary colors, wherein each color sub-pixel in the periodically repeating arrangement is adjacent at least one color sub-pixel of a complementary primary color,

wherein said periodically repeating arrangement comprises first and second adjacent rows of color sub-pixel elements,
wherein the first row includes one color sub-pixel element of each of said first set of primary colors, the second row includes one color sub-pixel element of each of said second set of primary colors, and each row of said array of color sub-pixel elements includes sub-pixels of said first and second sets of primary colors, and
wherein each color sub-pixel element in the first row is vertically adjacent to a color sub-pixel element of a complementary primary color in the second row.

Dependencies are inferred from the claim text.
