Patent ID: 8872740

Claim:
A display apparatus comprising: 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, wherein the luminance correcting unit includes a reference operating time calculator that calculates the value of a reference operating time in which an temporal variation in luminance of each display element when the corresponding display element operates for a predetermined unit time on the basis of the video signal under a temperature condition is equal to an temporal variation in luminance of each display element when it is assumed that the corresponding display element operates on the basis of the video signal of a predetermined reference gradation value under a predetermined temperature condition, an accumulated reference operating time storage that stores an accumulated reference operating time value obtained by accumulating the value of the reference operating time calculated by the reference operating time calculator for each display element, a reference curve storage that stores a reference curve representing the relationship between the operating time of each display element and the temporal variation in luminance of the corresponding display element when the corresponding display element operates on the basis of the video signal of the predetermined reference gradation value under the predetermined temperature condition, a gradation correction value holder that calculates a correction value of a gradation value used to compensate for the temporal variation in luminance of each display element with reference to the accumulated reference operating time storage and the reference curve storage and that holds the correction value of the gradation value corresponding to the respective display elements, and a video signal generator that corrects the gradation value of the input signal corresponding to the respective display elements on the basis of the correction values of the gradation values held by the gradation correction value holder and that outputs the corrected input signal as the video signal.
