DISPLAY DEVICE AND METHOD FOR CONTROLLING THE SAME
First Claim
1. A display device comprising:
- a plurality of pixels each of which includes an electroluminescent (EL) element and a drive transistor which controls a current flowing through the EL element;
a gate driver circuit which applies, to each of the plurality of pixels, a compensation voltage for compensating a threshold voltage of the drive transistor, in each of compensation voltage application periods included in a period other than a period in which a video signal voltage is applied; and
a control circuit which controls the gate driver circuit,wherein the control circuit adjusts a length of, among the compensation voltage application periods, a preceding compensation voltage application period immediately before the video signal voltage is applied.
