Abstract:
1. A display device, comprising: a display panel including gate lines and data lines; a signal controller configured to generate control signals for driving the display panel; a graphic processing unit configured to transmit input image data to the signal controller; a gate driver configured to drive the gate lines; and a data driver configured to drive the data lines, wherein the display panel is driven at a first frequency when a moving image is displayed on the display panel and driven at a second frequency lower than the first frequency when a still image is displayed on the display panel, wherein the signal controller comprises: wherein the data driver is configured to apply an auxiliary voltage corresponding to the auxiliary image data to the data lines in a vertical blank period when the still image is displayed, wherein the auxiliary image data is a difference of the representative value and a kick-back correction gray value that depends on the representative value, and wherein the kick-back correction gray value is a value calculated by a function generated by linear interpolation using a kick-back correction gray value at a minimum gray, a kick-back correction gray value at a maximum gray, and a gray value when the magnitude of the kick back correction gray value is maximum.
