Abstract:
A panel drive circuit having an input interface to which an image signal is input, a gamma correction circuit that corrects an image processing signal generated by an image processing circuit performing image processing on the image signal input to the input interface, such that a gamma correction signal thus generated has predetermined gamma characteristics, an unevenness correction circuit that corrects the gamma correction signal generated through the correction by the gamma correction circuit, based on correction data for reducing unevenness of a display panel, and an D/A convertor that has a variable output voltage range, and performs D/A conversion on an unevenness correction signal generated through the correction by the unevenness correction circuit and outputs the signal thus generated to the display panel, and the unevenness correction circuit changes the correction method according to the output voltage range of the D/A convertor.
