  • Publication number: 20090262146
    Abstract: A source driver performs inversion drive on a plurality of data lines of a liquid crystal panel. A differential interface receives brightness data of each pixel as a differential signal from a timing controller. A D/A converter converts the brightness data to a drive voltage of each pixel on the basis of a predetermined gamma correction curve according to the polarity of the inversion driving. An output buffer supplies the drive voltage of each pixel to a data line.
