摘要:
There is provided a display device including a display unit having pixels, each of which includes a luminescence element for individually emitting light depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a picture signal, scan lines which supply a selection signal for selecting the pixels to emit light to the pixels in a predetermined scanning cycle, and data lines which supply the picture signal to the pixels, the pixels, the scan lines, and the data lines arranged in a matrix pattern, the display device including: a luminescence amount detector for inputting a picture signal with a linear characteristic to detect a luminescence amount from the picture signal; a luminescence time calculator for calculating a luminescence time for the luminescence element based on the luminescence amount detected by the luminescence amount detector; a luminescence time recorder for recording the calculated luminescence time; a luminance acquirer for acquiring luminance information of the luminescence element by use of the luminescence time recorded in the luminescence time recorder; a coefficient calculator for calculating a coefficient by which the picture signal is multiplied, based on the luminance information acquired by the luminance acquirer; and a coefficient multiplier for multiplying the picture signal by the coefficient calculated by the coefficient calculator.
