Abstract
A pixel circuit includes first, second, and third transistors, and first and second capacitors, wherein the first transistor is controlled by a scan line and is configured to controllably couple a data line to the first capacitor and a gate electrode of the second transistor, the second transistor is controlled by a voltage provided by the first and second capacitors, the third transistor is controlled by the scan line and is configured to controllably couple a first power supply to the second capacitor, and the first power supply is controllably coupled to a light source by the second transistor.
