Abstract
A display device includes a display panel having gate lines and data lines, a signal controller driving the display panel, a graphic processing unit transmitting input image data to the signal controller, a gate driver driving the gate lines, and a data driver driving the data lines. The display panel is driven at a first frequency when displaying a moving image and driven at a lower frequency when displaying a still image. The signal controller includes a frame memory storing the input image data, a calculator calculating a representative value of image data stored in the frame memory, a line memory storing the representative value, and a kick-back corrector generating auxiliary image data by correcting the representative value according to a kick-back voltage. The data driver applies an auxiliary voltage corresponding to the auxiliary image data to the data lines in a vertical blank period when displaying the still image.
