Abstract:
A pixel circuit includes a light emitting element, a driving transistor which applies a driving current to the light emitting element, a write transistor which receives a write gate signal and a data voltage and is connected to a first electrode of the driving transistor, a first compensation transistor which receives a compensation gate signal and is connected to a second electrode of the driving transistor and a first electrode of a second compensation transistor, the second compensation transistor which receives the compensation gate signal, and is connected to the second electrode of the first compensation transistor and a control electrode of the driving transistor, a storage capacitor which receives a first power voltage and is connected to the control electrode of the driving transistor, and a node control transistor which receives the write gate signal and is connected to the second electrode of the first compensation transistor.
