  • Apparatus and method for driving liquid crystal display device
    Patent number: 8106877
    Abstract: A driving apparatus of a liquid crystal display device for reducing or automatically restoring a driving current of a light source by being inversed or re-inversed a phase of a driving current with which a light source of a liquid crystal display device is supplied by the human body is disclosed. In the driving apparatus of the liquid crystal display device, a driving controller reduces or restores a duty ratio of a driving control signal which controls a generation of a driving current of a backlight assembly in accordance with whether a predetermined enable signal is applied or not. A master inverter reduces or restores a level of a driving current of the backlight assembly in accordance with a duty ratio of a driving control signal from the driving controller. A slave inverter reduces or restores a level of a driving current of the backlight assembly in accordance with a duty ratio of the driving control signal.
