摘要： A display device including: a display panel; and a signal controller which controls signals for driving the display panel, where the signal controller includes a representative value generator which sequentially operates a portion of image data of one frame, where the representative value generator moves a last position digit into another position digit of the portion of the image data and generates a representative value representing a portion of a frame image corresponding to the portion of the image data; a storage portion which stores the representative value therein; and a comparator which compares the representative values of present and prior frames to determine whether the 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 for the still image is lower than a driving frequency for the motion picture.

摘要： A gate-on voltage applied to a third gate line connected to the current stage pixel is configured to be applied during any one or more of a first pre-charge period, a second pre-charge period, and a main-charge period. Data voltages are applied, in order, to a before-previous stage pixel, a previous stage pixel, and a current stage pixel, and the signal controller is configured to control the gate driver to selectively apply the gate-on voltage to the gate line connected to the current stage pixel during at least one of the first pre-charge period while the before-previous stage pixel is being charged and the second pre-charge period while the previous stage pixel is charged, so as to at least partially pre-charge the current stage pixel.
