Abstract
A display device includes a display including a plurality of pixels having a plurality of light-emitting elements, a pixel selector configured to select a pixel from among a plurality of pixels, a positional information generator configured to generate the positional information representing the position of the selected pixel, and a light emission processor configured to superpose the positional information on the light emitted by the selected pixel. A position detecting device is used to detect and output the positional information superposed on the light of the selected pixel on the display device, thus making it easy to accurately detect the position of the pixel subjected to calibration in luminance.
