Classification: CPC G | IPC G

Claim 9:
10. A display apparatus comprising:
a display panel comprising a pixel;
a gate driver configured to provide a gate signal to the pixel;
a data driver configured to provide a data voltage to the pixel; and
an emission driver configured to provide an emission signal to the pixel,
wherein the pixel comprises:
a light emitting element;
a driving switching element configured to apply a driving current to the light emitting element;
a bias switching element configured to provide a bias voltage to an input electrode of the driving switching element; and
a second transistor including a control electrode configured to receive a data write gate signal, an input electrode configured to receive the data voltage and an output electrode connected to a fourth node,
wherein a frequency of a bias gate signal applied to a control electrode of the bias switching element is greater than a frequency of the data write gate signal applied to the pixel,
wherein the pixel further comprises:
a first transistor including a control electrode connected to a first node, an input electrode connected to a second node and an output electrode connected to a third node; and
an eighth transistor including a control electrode configured to receive a second initialization gate signal, an input electrode configured to receive the bias voltage and an output electrode connected to the second node,
wherein the driving switching element is the first transistor and the bias switching element is the eighth transistor.
