ABSTRACT:
LCD unit includes first and second LCD panels stacked one on another. An image-data processing unit outputs monochrome image data to the second LCD panel, and color image data to the first LCD panel. The monochrome image data specifies a full transmission for a pixel having a luminance not less than a threshold, the original gray-scale level for a pixel having a luminance less than the threshold. The color image data is generated based on the monochrome image data and input image data.
