Abstract: A liquid crystal display (LCD) device are disclosed, which reduce power consumption and improve an image quality. The LCD device includes a liquid crystal panel in which a plurality of sub-pixels is defined by intersection of a plurality of gate lines and a plurality of data lines, and sub-pixels adjacent to each other in a column direction are connected by sharing the plurality of gate lines. A gate driver may sequentially transfer a scan pulse to even-numbered gate lines and then sequentially transferring a scan pulse to odd-numbered gate lines. A data driver may be synchronized with the applied scan pulse in providing data voltage to columns of sub-pixels. The data driver provides the data voltage having different polarities to a neighbor data line during one frame interval such that sub-pixels are driven by a horizontal 2-dot inversion scheme.

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.
