Abstract
A pixel of an organic light emitting diode display device includes a scan transistor configured to connect a data line to a first node in response to a scan signal, a storage capacitor connected between the first node and a first power supply voltage, a compensation capacitor connected between the first node and a second node, a driving transistor having a gate connected to the second node, a source connected to the first power supply voltage, and a drain connected to a third node, a compensation transistor configured to connect the second node to the third node in response to a compensation control signal, an organic light emitting diode connected between the third node and a second power supply voltage, and an initialization transistor configured to transfer an initialization voltage in response to an initialization control signal.
