ABSTRACT:
A method is provided for driving a liquid crystal display capable of preventing degradation of linearity of a gamma characteristic, of achieving display of a high quality image in a simple and low-priced configuration and of solving problems associated with environmental changes, frequency characteristic of timing signals, change in a gamma characteristic caused by luminance of a backlight, or dispersion in a gamma characteristic occurring during processes of manufacturing a color liquid crystal display. The method includes acquirement of first corrected red data, first corrected green data, and first corrected blue data each being of 10 bits to which information to change a gray scale two or more times for every red data, green data, and blue data has been added when a gamma correction is made to red, green, and blue data each being of 8 bits and generation of data red, green, and blue signals to be fed to a data electrode of a liquid crystal display to perform frame rate control.
