Abstract:
1. A pixel circuit comprising: a light emitting device comprising a first electrode and a second electrode; a first transistor comprising a first electrode and a second electrode and for outputting a driving current according to a voltage applied to a gate electrode of the first transistor; a first capacitor comprising a first terminal, and a second terminal coupled to the gate electrode of the first transistor; a second transistor for transferring a data signal to the first terminal of the first capacitor in response to a scan control signal applied to a gate electrode of the second transistor; a third transistor for diode-connecting the first transistor in response to the scan control signal applied to a gate electrode of the third transistor; a fourth transistor for applying a first power voltage to the first electrode of the first transistor in response to an emission control signal; a fifth transistor for applying a sustain voltage to the first terminal of the first capacitor in response to the emission control signal; and a sixth transistor for applying the first power voltage to the second terminal of the first capacitor in response to an initialization control signal, wherein the first transistor and the second to sixth transistors are N-type transistors.
