Classification: CPC G | IPC G

Claim 0:
1. 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 storage capacitor including a first electrode connected to the fourth node and a second electrode connected to a control electrode of the driving switching element.
