Abstract:
A display driver includes a gamma correction data transmission unit that transmits a plurality of gamma correction data pieces one by one in each predetermined period. A brightness level indicated by a video signal is converted into a gradation voltage with a gamma characteristic based on the gamma correction data piece transmitted from the gamma correction data transmission unit.
