Abstract: A display device includes a timing controlling unit configured to generate an image data, a data control signal and a gate control signal; a data driving unit configured to generate a data signal using the image data and the data control signal; a gate driving unit configured to generate a gate1 signal, an odd gate2 signal, an even gate2 signal, a gate3 signal, a gate4 signal and an emission signal using the gate control signal; and a display panel displaying an image using the gate1 signal, the odd gate2 signal, the even gate2 signal, the gate3 signal, the gate4 signal and the emission signal. A rising timing of the emission signal and a falling timing of the gate3 signal are changed according to a duty ratio.

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.
