  • Publication number: 20110050737
    Abstract: A method for adjusting a chromaticity of a liquid crystal display (LCD) is provided. Firstly, a light-on-test is performed to a plurality of backlight modules according to a standard gamma curve of a liquid crystal panel to obtain a color space of a plurality of LCDs formed by the backlight modules and the liquid crystal panel. The color space has a plurality of chromaticity coordinate values for representing chromaticities of the LCDs. The standard gamma curve is a relation curve of brightness corresponding to different gamma voltages inputted to the liquid crystal panel. Next, the color space is divided into a predetermined chromaticity area and a plurality of adjusting chromaticity areas according to a standard chromaticity range. Finally, a plurality of gamma voltage adjusting values corresponding to the adjusting chromaticity areas is obtained according to the relative position relationship between the adjusting chromaticity areas and the predetermined chromaticity area.
