Claim:
1. An organic light emitting diode display comprising: a plurality of pixels configured to store a first data signal received through a corresponding data line during a scan period and to emit light according to a second data signal during a light emitting period of a frame, wherein the first data signal corresponds to the frame and the second data signal corresponds to a previous frame, and the scan period overlaps the light emitting period, and each of the plurality of pixels comprising: a first transistor configured to connect the data line and a first node; a sustain capacitor coupled between the first node and a reference voltage applying line; a third transistor configured to connect the first node and a second node; a driving transistor and an organic light emitting diode connected in series between first and second power voltage applying lines; a compensation capacitor connected between the second node and a gate electrode of the driving transistor, the compensation capacitor and the third transistor being connected in series between the first node and the gate electrode of the driving transistor; a second transistor configured to connect the sustain capacitor and the reference voltage applying line; and a fourth transistor configured to transmit a bias voltage to the second node.
