Abstract
A liquid crystal display device includes a gate driver, a source driver and a common driver. An input video signal is stored in a line memory and a gray scale with which an applied voltage becomes highest is detected from data corresponding to 1 line among the signal. A common electrode is driven by a common voltage being reduced in accordance with the gray scale and having a low effective value. The driver is driven by an output controlled in accordance with the voltage thus reduced. A voltage applied to a common electrode is set by using a LUT and a common voltage is set by using a LUT. It is therefore possible to provide a liquid crystal display device and a method of driving the liquid crystal display device, each of which can reduce power consumption.
