Abstract
The present gamma correction circuit is provided with a memory for supplying correction data for the gamma correction of the luminance of a display means, and a selector for selecting either from N-bit uncorrected digital display data and corrected data for outputting as driving data for the display means. A liquid crystal driver is provided with gamma correction means for gamma-correcting the luminance of a liquid crystal panel inputting the N-bit digital display data for liquid crystal displaying and means for converting the N-bit digital display data into analog data, the gamma correction means comprises a gamma correction circuit of the invention. A liquid crystal display device is provided with a liquid crystal display panel inputting the N-bit digital display data for liquid crystal displaying, and gamma correction means or a liquid crystal driver for gamma-correcting the luminance of the liquid crystal display panel. The gamma correction means or the liquid crystal driver comprises a gamma correction means or a liquid crystal driver of the present invention.
