Abstract:
A pixel circuit includes a first switch element turned on by a gate-on voltage of a first scan pulse to apply a data voltage to a first node; a second switch element turned on by a gate-on voltage of a second scan pulse to connect a second node to a third node; a third switch element turned on by a gate-on voltage of a light-emitting control pulse to apply a reference voltage to the first node; a fourth switch element turned on by the gate-on voltage of the light-emitting control pulse to connect the third node to a fourth node; and a fifth switch element turned on by a gate-on voltage of the second scan pulse to apply the reference voltage to the fourth node. A voltage higher than or equal to the pixel driving voltage is applied to the third node before generation of the first scan pulse.
