Abstract:
A pixel circuit includes: a driving switching element; a data initializer to initialize a voltage of a control electrode of the driving switching element; a data writer to write a data voltage to the driving switching element; an organic light emitting element; an organic light emitting element initializer to initialize an anode electrode of the organic light emitting element to a second initialization voltage based on an organic light emitting element initialization gate signal; and a light emitting controller to control an emission of the organic light emitting element. The organic light emitting element initializer includes: a control electrode to receive the organic light emitting element initialization gate signal; an input electrode to receive the second initialization voltage; an output electrode connected to the anode electrode; and a conductive layer to receive a compensation control signal that is different from the organic light emitting element initialization gate signal.
