Abstract:
A pixel including: a light emitter; a first transistor including first and second electrodes respectively connected to power and the light emitter, the first transistor controlling driving current; a first capacitor between a second and third node; a second transistor between the third node and data line and turned on by a scan signal; a third transistor between a first and second node, and turned on by a control signal; a fourth transistor between power and the third node, and turned on by a emission control signal; a fifth transistor between power and the first electrode, and turned on by the emission control signal; a sixth transistor between the second node and the light emitter, and turned on by another emission control signal; and a second capacitor between power and the first node, wherein the fourth, fifth and sixth transistors turn-on/off at least four times in a non-emission period.
