20100134473 | LIQUID CRYSTAL DISPLAY DEVICE - In a liquid crystal display device performing alternating-current driving, at least one of a gate voltage amplitude Vgp−p(p) upon application of a positive polarity voltage and a gate voltage amplitude Vgp−p(n) upon application of a negative polarity voltage is changed in accordance with a liquid crystal driving frequency. Thus, an effective value of a liquid crystal application voltage in a positive polarity is set to be equal to an effective value of a liquid crystal application voltage in a negative polarity irrespective of the liquid crystal driving frequency, so that flicker is prevented from occurring when the liquid crystal driving frequency is switched. As the liquid crystal driving frequency is low, a gate low voltage Vgln after application of the negative polarity voltage is set to be low. Thus, a leak current from a TFT is reduced in the negative polarity, and a liquid crystal element is improved in voltage holding ratio. | 06-03-2010 |

20130044098 | LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD OF A LIQUID CRYSTAL DISPLAY DEVICE - 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. | 02-21-2013 |
