    • A pixel circuit including an organic light emitting diode (OLED), a first transistor, a first capacitor, a second transistor, a second capacitor and a third transistor is disclosed. In one aspect, the first transistor controls the amount of current flowing from a first power source to a second power source via the OLED, corresponding to a voltage at a first node. The first capacitor has a first terminal connected to a data line. The second transistor is connected between a second terminal of the first capacitor and a second node. The second capacitor is connected between the second node and the first node. The third transistor is connected between a fixed voltage source and the second terminal of the first capacitor, and has a turn-on period non-overlapping with that of the second transistor.
