Abstract
A pixel of a display with reduced leakage current is disclosed. The pixel includes: an organic light emitting diode; a first transistor for controlling an amount of current flowing from a first power source to a second power source via the organic light emitting diode; a storage capacitor coupled between the first power source and a gate electrode of the first transistor; a plurality of third transistors coupled between the gate electrode and a second electrode of the first transistor; and a plurality of fourth transistors coupled between the gate electrode of the first transistor and an initialization power source. The third and fourth transistors are configured to reduce a leakage current from the storage capacitor to improve the image quality of the display.
