Abstract:
1. A display device equipped with a display unit in which light emitting elements which self-emits light according to current amount are arranged in a matrix form, the display device comprising: a receiving part for receiving a difference signal of a plurality of channels including an image signal and content identification information for defining a type of content inserted in a blanking period of at least one channel, and outputting the image signal and the content identification information; a light emission amount regulation part for setting a reference duty for defining a light emission amount per unit time in the respective light emitting element according to image information of the image signal; an adjustment part for adjusting so that an actual duty defining a light emission time for light emitting the light emitting element per unit time is within a predetermined range based on the reference duty and an adjustment signal, and adjusting a gain of the image signal so that a light emission amount defined by the actual duty and the gain of the image signal becomes the same as the light emission amount defined by the reference duty; and an adjustment signal generation part for generating the adjustment signal for setting a lower limit value of the actual duty based on the content identification information.
