Abstract: A display device is provided. A display panel includes pixels configured to display an image. An illumination sensor measures an illumination of ambient light of the display panel. A controller controls the display panel so that the luminance of the pixels decreases during a first time interval when the illumination of the ambient light decreases and controls the display panel so that the luminance of the pixels increases during a second time interval when the illumination of the ambient light increases. The first time interval is shorter than the second time interval.
