Abstract
A display device includes a display panel including a pixel which receives a luminance control voltage, a driving controller which receives an input image signal and a control signal and provides an output image signal to the display panel, and a voltage generator which generates the luminance control voltage in response to a voltage control signal from the driving controller. The driving controller determines a current operating frequency based on the control signal, and outputs the voltage control signal based on a difference value between the current operating frequency and a previous operating frequency and an operating time of the previous operating frequency when the current operating frequency is different from the previous operating frequency, where the luminance control voltage is changed from a first voltage level to a second voltage level based on the voltage control signal.
