Abstract
A display apparatus includes a display panel, a gate driver, and a gate driving control circuit. The gate driver is connected to the display panel, and generates gate signals for driving the display panel using a gate clock signal. The gate driving control circuit generates the gate clock signal using a gate on voltage and a gate off voltage, determines whether an operation environment is an abnormal temperature environment by comparing a first feedback gate signal with a second feedback gate signal, and adjusts a voltage level of the gate clock signal in the abnormal temperature environment. The first feedback gate signal is retrieved from the display panel while a first frame image is displayed on the display panel. The second feedback gate signal is retrieved from the display panel while a second frame image subsequent to the first frame image is displayed on the display panel.
