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.

Abstract: A display device includes a display panel including a pixel and a driving controller to drive the display panel. The driving controller generates a compensating signal, when a first driving frequency of a first frame is determined as being higher than a second driving frequency of a second frame by comparing a first cycle count value of the first frame with a second cycle count value of the second frame subsequent to the first frame.
