Patent ID: 7411589

Claim:
A color liquid crystal display (CLCD) system, comprising: a CLCD having therein multiple substantially red (R), green (G), and blue (B) pixels, each pixel adapted to receive excitation in varying magnitude so as to cause different amounts of R, G, and B light to exit each pixel in response to the excitation, wherein the CLCD includes an input for receiving excitation information for the pixels; and a processor having an output coupled to the input of the CLCD for supplying the excitation information thereto, and for receiving at least one character code defining a character pixel map comprising an array of pixels having multiple values therein within a pixel pattern outline for a character to be displayed by the CLCD, and at least one color code defining a staggered spatial shading color map determinative in part of a color in which the character is to be displayed by the CLCD, the processor operable to combine the staggered spatial shading color map with the character pixel map to produce a composite pixel map incorporating both staggered spatial shading and gray level mixing for the pixels of the CLCD and to supply the excitation information to the CLCD based at least in part on the composite pixel map.
