Abstract
A lighting emitting display, a pixel circuit and a driving method thereof. The pixel circuit includes a driving transistor, a capacitor and a LED. The capacitor receives a first supply voltage and is coupled to a gate of the driving transistor. A cathode of the LED receives a second supply voltage. During a pre-charge period, the gate and the drain of the driving transistor are coupled to an anode of the LED, the source of the driving transistor is coupled to a charging voltage. The source of the driving transistor receives a data signal and the drain and gate of the driving transistor are coupled to each other during a programming period. The source of the driving transistor is coupled to receive the first supply voltage and the drain of the driving transistor is coupled to the anode of the LED during a display period.
