Abstract:
A pixel circuit including an organic light-emitting element, a switching transistor, a storage capacitor that stores a data signal applied via a data line, a driving transistor that allows a driving current corresponding to the data signal to flow into the organic light-emitting element, an emission control transistor electrically connected to the organic light-emitting element and the driving transistor in series, and sync transistors electrically connected to a bottom metal electrode of the driving transistor. The sync transistors include a first sync transistor electrically connected to a first one selected from a source electrode of the driving transistor, a gate electrode of the driving transistor, the high power voltage, and the low power voltage and a second sync transistor electrically connected to a second one selected from the source electrode of the driving transistor, the gate electrode of the driving transistor, the high power voltage, and the low power voltage.
