DRIVE METHOD AND DISPLAY DEVICE
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 T21 is started by switching only the enable switch to an electrically conductive state before a period T22 in which the drive transistor is initialized, and the period T22 following the period T21 is started by switching the switch to an electrically conductive state. The period T21 is longer than a period T24 in which a threshold voltage of the drive transistor is compensated.
