Abstract
A display driver according to the present invention generates a plurality of driving voltages based on a video signal and applies the respective driving voltages to a plurality of source lines of a display panel. The display driver includes an overdrive part and an overdrive control circuit. The overdrive part executes an overdrive processing to increase amplitudes of the driving voltages. The overdrive control circuit detects an internal temperature of the display driver and stops the overdrive processing by the overdrive part when the temperature is higher than a predetermined temperature threshold.
