Abstract:
A display apparatus includes: a display panel that includes display elements having a current-driven light-emitting portion, in which the display elements are arranged in a two-dimensional matrix in a first direction and a second direction, and that displays an image on the basis of a video signal; and a luminance correcting unit that corrects the luminance of the display elements when displaying an image on the display panel by correcting a gradation value of an input signal and outputting the corrected input signal as the video signal. The luminance correcting unit includes a reference operating time calculator, an accumulated reference operating time storage, a reference curve storage, a black-level shift amount holder, and a video signal generator.
