ABSTRACT:
An LCD with power consumption reduction and a method of driving the same. In one embodiment, the LCD has a plurality of pixels spatially arranged in the form of a matrix having N pixel rows, each pixel row defined between two neighboring scanning lines Gnand Gn+1, and having an auxiliary common electrode, and a plurality of common voltage driving circuits, each common voltage driving circuit electrically coupled between the scanning line Gnand the corresponding auxiliary common electrode for providing a two-level lift-up coupling voltage to the auxiliary common electrode.
