Abstract:
1. A display device comprising: a display panel; and a signal controller which controls signals for driving the display panel, wherein the signal controller comprises: a representative value generator which sequentially operates at least a portion of image data of one frame, wherein the representative value generator moves a last position digit into another position digit of the at least a portion of the image data of the one frame and generates a representative value representing at least a portion of a frame image corresponding to the at least a portion of the image data of the one frame; a storage portion which stores the representative value therein; and a comparator which compares the representative value of a present frame and the representative value of a prior frame to determine whether the at least a portion of the frame image is a still image or a motion picture, and the signal controller controls the signals for driving the display panel such that a driving frequency when the at least a portion of the frame image is the still image is lower than a driving frequency when the at least the portion of the frame image is the motion picture.
