Abstract
By a drive method, for each of a plurality of display pixels each including an EL element, a capacitor, a drive transistor, an enable switch, and a switch, a period Tis started by switching only the enable switch to an electrically conductive state before a period Tin which the drive transistor is initialized, and the period Tfollowing the period Tis started by switching the switch to an electrically conductive state. The period Tis longer than a period Tin which a threshold voltage of the drive transistor is compensated.
