摘要： 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.

摘要： When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have a constant potential. A gate voltage is changed from Vgh to Vgl at the same time as when the control signal was changed from the value H to the value L. As a result, the gate of each TFT returns to the OFF state from the ON state. The control signal remains at the value L until the idle period is over. In other words, when the next driving period is started, the voltage of the control signal is changed from the value L to the value H. As a result, the analog amplifiers in the signal line driver circuit are switched back to the normal state from the low-driving power state.
