ABSTRACT:
A display pixel including a light-emitting element and a drive element for supplying current flowing in a current path to the light-emitting element is applied with a detection voltage based on a predetermined unit voltage. Based on a value of current flowing in the current path of the drive element, a specific value corresponding to an element characteristic of the drive element is detected. A gradation voltage corresponding to a luminance gradation of display data is generated. Based on the specific value and the unit voltage, a compensated voltage is generated. By compensating the gradation voltage based on the compensated voltage, a compensated gradation voltage is generated. And the compensated gradation voltage is supplied to the display pixel.
