    Abstract: A pixel includes an organic light emitting diode, a first driver and a second driver. The second driver controls an amount of current supplied from a first power source to the organic light emitting diode, corresponding to a previous data signal. The first driver stores a current data signal supplied from a data line and supplies the previous data signal to the second driver. In the pixel, the second driver includes a sixth transistor coupled between an initialization power source and a first node coupled to a gate electrode of a first transistor, the sixth transistor being configured to turn on when a first control signal is supplied; and a seventh transistor coupled between the first power source and a second node commonly coupled to the first and second drivers, the seventh transistor being configured to turn on when the first control signal is supplied.

    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.
