Abstract: A display device for improving display quality includes a pulse compensator, a gate driver, a source driver and a display panel. The pulse compensator generates a clock signal of which amplitude decreases when peripheral temperature increases and increases when peripheral temperature decreases. The gate driver outputs a gate driving signal to the display panel based on the clock signal, wherein an amplitude of the gate driving signal decreases when the peripheral temperature increases and the amplitude of the gate driving signal increases when the peripheral temperature decreases. The source driver provides a gray-scale voltage based on gray-scale data, and the display panel displays an image corresponding to the gray-scale voltage in response to the gate driving signal. Therefore, the deterioration in the drive capability of the gate driver depending on the peripheral temperature may be prevented and display quality of the display device may be improved.
