ABSTRACT:
A display device corrects uneven luminance due to uneven element characteristics by simple measurement and correction with a low cost. The display device includes pixels that each include a light emitter and a driver. Data lines supply a voltage signal to the driver of each pixel. A data line driver supplies the voltage signal to each data line. A first memory stores, for each pixel, a luminance gain for adjusting a luminance corresponding to a video signal to a standard luminance. A second memory stores conversion curve information representing a representative conversion curve common to the pixels. A corrector converts, for each pixel, the luminance into a corresponding standard luminance value based on a corresponding luminance gain stored in the first memory, while a converter converts, for each pixel, the corresponding standard luminance into a corresponding voltage signal based on the conversion information stored in the second memory.
