The invention provides a GAMMA curvature correction and color-temperature automatic regulating method for liquid crystal display and the system. The said system consists of a system host-machine, a detector, a color analyzer, a video standard signal source, a data interface,and a system measure and correction software, which can perform GAMMA curvature correction and white balance adjustment for multi-purpose TV and computer display including LCD and high-resolution back projection and multi-structure liquid crystal display including TN, STN, DSTN and TFT to improve the videograph display quality of the liquid crystal display. The system host-machine connects multiple video signal sources, automatic measurement and correction software for GAMMA curvature and color-temperature and data interface together, the system parameter can be set manually or automatically, the system configuration is simple, GAMMA curvature correction and white balance adjustment software can be conveniently transferred, and can rapidly finish automatic measurement and correction for GAMMA curvature and color-temperature and can visually inspect the effect. The invention can be used in departments including scientific research, production, quality inspection and maintenance and can visually finish the GAMMA curvature correction and white balance adjustment for the LCD products with high accuracy and quick-speed.
