Abstract
On a panel, a plurality of PVDD lines, each of which corresponds to a horizontal line of pixels and supplies power to the pixels of the horizontal line, are provided. A voltage drop correction unit that obtains a voltage drop before reaching the pixel, based on resistance in the plurality of power supply lines and currents flowing therein, and corrects display data so as to cancel the obtained voltage drop of the pixel. A display unevenness correction unit that corrects uneven brightness caused by a variation in a TFT characteristic of the pixel by performing a calculation using display data of the pixel and obtained correction data of the pixel.
