Abstract:
1. A liquid crystal display (LCD) system comprising: a LCD unit displaying a color image and including at least one LCD panel and a light source driven by a dot-matrix drive scheme; and an image-data processing unit receiving input image data to generate output image data for driving said LCD unit, said image-data processing unit including: a monochrome-image generation section for generating monochrome image data based on said input image data to output said monochrome image data to said light source, said monochrome image data specifying a full transmission for a first pixel having a luminance or chromaticness which is not less than a threshold, and specifying a first gray-scale level for a second pixel having a luminance or chromaticness which is less than said threshold, said first gray-scale level corresponding to an original gray-scale level of said second pixel specified in said input image data; and a color-image generation section for generating color image data based on said input image data and said monochrome image data to output said color image data to said LCD panel, said light source controlling luminance of each dot of pixel in said LCD panel based on said monochrome image data.
