Abstract:
1. A color image display apparatus, comprising: a color separation circuit that separates image data for each color component to accumulate the image data; a shutter control circuit that slices the color component data, which has been subjected to color separation with said color separation circuit, in accordance with a slice level; a light source control circuit that controls a light source corresponding to the color component data in synchronization with said shutter control circuit; one or more light sources that is turned on or off in accordance with an instruction from said light source control circuit; a converting device that converts an optical path of light from said light source; a shutter which makes light from a corresponding pixel pass there through and cuts off the light based on an instruction from said shutter control circuit and which is made of liquid crystal as a main material; and a timing circuit that generates operation timings for said color separation circuit, said shutter control circuit, and said light source control circuit, in which: said shutter control circuit transfers one line of slice data to the shutter sequentially on a slice level basis; said light source control circuit turns on said light source corresponding to the slice data; and said shutter makes the light from said light source, which corresponds to the slice data representing gradation of the corresponding pixel, pass there through and cuts off the light to display an image.
