Abstract
A driving method of an image display device includes detecting an amount of data change of an input image and calculating a moving speed of the input image, determining whether the image moving speed is within a preset reference range, when the image moving speed is within the reference range, driving a display screen according to an input frame frequency synchronized to the input image, and when the image moving speed is out of the reference range, down-modulating a frame frequency for displaying the input image to a frequency lower than the input frame frequency and driving the display screen according to a modulated frame frequency.
