    摘要： A display device includes a display panel for displaying a still image and for displaying a motion picture. The display panel includes a gate line, a data line, a storage electrode line, a first switching element connected to the gate line and the date line, a storage connected to the switching element and the storage electrode line. The display device further includes a signal controller for providing controlling signals to drive the display panel. The display panel is driven at a first frequency when the motion picture is displayed. The display panel is driven at a second frequency lower than the first frequency when the still image is displayed. When the display panel is driven at the second frequency, a common voltage inputted to the storage electrode line changes.

    摘要： 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.

    摘要： In order to reduce power consumption of a display device when a still picture is to be displayed, a display area of the device is subdivided into a plurality of Still Picture Refresh Groups (SPRGoP's), with each SPRGoP consisting of n pixels. All n of the pixels are charged in every one of sequential frames when a motion picture mode is in effect. Less than all of the n pixels of each SPRGoP are refreshed in each frame of an N-frame refresh cycle when a still picture mode is in effect. Different schemes for cycling through the n pixels of each SPRGoP are disclosed.
