Patent ID: 8294642

Claim:
A display device including a display unit having pixels, each of which includes a luminescence element that individually becomes luminous depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a voltage signal, scan lines which supply a selection signal for selecting pixels to be luminous to the pixels in a predetermined scanning cycle, and data lines which supply to the pixels the voltage signal according to an input picture signal, the pixels, the scan lines, and the data lines arranged in a matrix pattern, the display device comprising: a luminescence amount regulator that sets a reference duty for regulating a luminescence amount for each one frame, according to the input picture signal; and an adjuster that adjusts an effective duty that regulates, for each one frame, a luminous time for which the luminescence element is luminous, and a gain of the picture signal, based on the reference duty and the input picture signal, wherein, the adjuster adjusts the effective duty and the gain of the picture signal so that the luminescence amount for each one frame regulated by the reference duty and the picture signal equals to a luminescence amount for each one frame regulated with the adjusted effective duty and the adjusted gain of the picture signal, and the adjuster includes: a luminous time that adjusts for adjusting the effective duty, based on a maximum value of luminance of the picture signal for a predetermined period and the reference duty; and a gain adjuster that adjusts the gain of the picture signal, based on the reference duty set by the luminescence amount regulator and the effective duty adjusted by the luminous time adjuster.
