Abstract:
A pixel circuit including an organic light emitting diode, a first transistor configured to drive the organic light emitting diode, a second transistor electrically connected between a gate node of the first transistor and a data line, a third transistor electrically connected between a source node of the first transistor and an initialization voltage line and a storage capacitor electrically connected between the gate node and the source node of the first transistor. In a data writing period in which the storage capacitor is charged with electric charges, a turn-off time of the third transistor lags compared to a turn-off time of the second transistor.
