Abstract

See full text

A pixel is provided including an OLED having anode and cathode electrodes. A second transistor controls current supplied from a first power supply to a second power supply via the OLED. A first transistor is coupled between a gate electrode of the second transistor and a data line and is configured to turn on when a scan signal is supplied to a scan line. A first capacitor is coupled between the first power supply and the gate electrode. A second capacitor is coupled between the anode electrode and the gate electrode. A fourth transistor is coupled between the second capacitor and the anode electrode and is configured to turn on when a control signal is supplied to a control line. A third transistor is coupled between the second transistor and the anode electrode and is configured to turn off when a signal is supplied to a light emitting control line.
