Abstract:
1. A display device which has a display section in which pixels which have light emitting elements for emitting light according to a current amount and pixel circuits for controlling an electric current applied to the light emitting elements according to video signals, scanning lines which supply selection signals for selecting the pixels for emitting light to the pixels in a predetermined scanning cycle, and data lines which supply the video signals to the pixels are arranged into a matrix pattern, the display device comprising: a light emission amount detecting section configured to detect an amount of light emission from video signals; a light emitting time calculating section configured to calculate a light emitting time of the light emitting elements based on the amount of light emission detected by the light emission amount detecting section; a recording section configured to include (a) a section in which predetermined luminance information is stored and (b) a light emitting time recording section configured to record the calculated light emitting time; a luminance acquiring section configured to acquire the predetermined luminance information of the light emitting elements by using the light emitting time recorded in the light emitting time recording section to retrieve the predetermined luminance information from the recording section; a coefficient calculating section configured to calculate coefficients by which the video signals are multiplied based on the predetermined luminance information acquired by the luminance acquiring section; and a coefficient multiplying section configured to multiply the video signals by the coefficients calculated by the coefficient calculating section.
