Abstract
Methods and apparatus are provided for a color liquid crystal display (CLCD). The apparatus includes a processor coupled to the CLCD for receiving a character code and a color code and translating them into character and color pixel arrays that are overlaid and summed to produce a composite pixel array corresponding to the CLCD pixel array, where each entry in the composite array is used in conjunction with a color table to establish drive levels for each pixel in the CLCD. The character pixel array includes gray level color mixing and the color pixel array includes spatial shading color mixing, so that the composite array uses both techniques to determine the individual CLCD pixel drive levels to provide a wider range of color choices without significant color dependence on viewing angle.
