Abstract:
A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver is configured to provide a gate signal to the pixel. The data driver is configured to provide a data voltage to the pixel. The emission driver is configured to provide an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element and a bias switching element. The driving switching element is configured to apply a driving current to the light emitting element. The bias switching element is configured to provide a bias voltage to an input electrode of the driving switching element. A frequency of a bias gate signal applied to a control electrode of the bias switching element is greater than a frequency of a data write gate signal applied to the pixel.
