Abstract
A self-luminescent display device includes a pixel unit in which a plurality of pixels including a self-luminescent pixel is arranged, an external light sensor which measures an external light intensity, a temperature sensor which measures an environmental temperature, an image correcting unit which corrects image data input to the image correcting unit on the basis of statistical data of the image data, a light adjusting unit which produces a light adjusting signal on the basis of a measurement signal of the external light sensor, a temperature control unit which produces a temperature correcting signal on the basis of a measurement signal of the temperature sensor, and a display control unit which produces a brightness correcting signal for correcting light emitting brightness of the pixels in the pixel unit on the basis of the light adjusting signal and the temperature correcting signal. The light emitting brightness of the pixels in the pixel unit is adjusted on the basis of the image data corrected by the image correcting unit and the brightness correcting signal.
