COLOR LIQUID CRYSTAL DISPLAY AND GAMMA CORRECTION METHOD FOR THE SAME

摘要

A color liquid crystal display is provided where the viewing angle dependence of the ? characteristic is improved by employing a pixel division method and display with high color reproducibility can be achieved when the screen is viewed not only front the front but also at an angle. By referring to the correction tables for R, G, and B, the following ? correction is performed independently for R, G, and B to achieve good color tracking. The chromaticity of the front view shifts toward blue in an oblique hue correction range (IL) defined according to the pixel division ratio etc. to reduce the shift of the chromaticity of an oblique view toward yellow in the oblique hue correction range (IL) while the color balance in the other ranges (the gray scale level from 32 to 255 excluding the oblique hue correction range) is maintained. This invention is suitable for a pixel-division color liquid crystal display.
