1. A display apparatus comprising:
a display panel including a pixel;
a data driver configured to provide data voltages to the pixel;
an emission driver configured to provide an emission signal to the pixel;
a gate driver configured to provide a gate signal to the pixel; and
a driving controller configured to control the data driver and the emission driver,
wherein the pixel comprises:
a first sub-pixel including a first pulse width modulator configured to output a first gate output signal for a pulse width modulation in response to a first pulse width data voltage and configured to control a period of a first driving current applied to a first light emitting element and a first pulse amplitude modulator configured to apply the first driving current to the first light emitting element in response to a first pulse amplitude data voltage different from the first pulse width data voltage;
a second sub-pixel including a second pulse width modulator configured to output a second gate output signal for the pulse width modulation in response to a second pulse width data voltage different from the first pulse width data voltage and configured to control a period of a second driving current applied to a second light emitting element and a second pulse amplitude modulator configured to apply the second driving current to the second light emitting element in response to a second pulse amplitude data voltage different from the second pulse width data voltage; and
an initializer configured to initialize the first gate output signal and the second gate output signal in response to a second initialization signal.
