Abstract
A pixel circuit includes a first path coupled to a gate of a driving transistor and a second path passing through a source and drain of the driving transistor. An initialization voltage of the driving transistor is set based on a gray scale data voltage carried along the first path. A voltage is stored in a capacitor coupled to the gate of the driving transistor based on the gray scale data voltage carried along the second path. The voltage stored in the capacitor is based on the gray scale data voltage, and may be compensated for variation in a threshold voltage of the driving transistor.
