Abstract
A pixel circuit includes a light emitting element, a write transistor configured to write a data voltage in response to a write gate signal, a driving transistor configured to generate a driving current based on the data voltage and to apply the driving current to the light emitting element, a compensation transistor configured to diode-connect the driving transistor in response to a compensation gate signal, a first initialization transistor configured to apply a first initialization voltage to a control electrode of the driving transistor in response to an initialization gate signal, and a second initialization transistor configured to apply a second initialization voltage to an anode electrode of the light emitting element in response to a bias gate signal having an activation period longer than at least one of the compensation gate signal and the initialization gate signal.
