Abstract: A driving circuit for a display device, for reducing power consumption of a data driver, and a method of driving the driving circuit are disclosed. The driving circuit includes a data driver for maintaining buffers of the data driver in an on state every preset specific frame period and maintaining the buffers in an off state every remaining period except for specific frame periods in a refresh mode for processing image data of one image for the specific frame periods only.
