Abstract

A display device includes: a display panel; and a frequency controller which receives an image data signal and an input frequency information and outputs the image data signal and a timing control signal. The frequency controller includes: an image processor which receives the image data signal; a frame memory which stores the image data signal; an output frequency determining unit which receives the input frequency information and determines an output frequency based on a variation amount of the input frequency; and an image output unit which receives the image data signal from the image processor, receives an output frequency information from the output frequency determining unit, and outputs the image data signal and the timing control signal. When an input frequency varies, the output frequency determining unit determines the output frequency based on the following equations:
