Abstract
Variance in luminance deterioration in a display is suppressed. A display device in which a self-illuminating display element is used to display information comprises a display component in which are disposed a plurality of pixels made up of a plurality of colors of sub-pixels, and a controller for controlling the drive of the display component. The controller records an accumulated luminance for each sub-pixel, and calculates a luminance adjustment amount for each sub-pixel based on the difference between the accumulated luminance values. The controller also detects when no one is viewing the display device, produces a corrected image according to the luminance adjustment amount, and displays the corrected image on the display component while no one is viewing the display device.
