Abstract
A display panel driver drives pixels based on first power having at least three voltage levels, second power having a constant voltage, and third power having two voltage levels. Each pixel includes a first transistor connected between first and second nodes and including a gate electrode to receive a scan signal, a second transistor connected between the second node and a third node in series with the first transistor and including a gate electrode to receive the third power, and a driving transistor connected between a source of the first power and the third node and including a gate electrode connected to the first electrode to control a driving current for an organic light emitting diode. A first capacitor is connected between a source of the third power and the first node, and a second capacitor is connected between the second node and one of the data lines.
