Abstract:
A driving system for a liquid crystal display device includes a system unit to supply image data to be displayed on a liquid crystal panel, the system unit generating a system dimming signal, an inverter unit to control luminance of a backlight unit, the inverter unit receiving the system dimming signal, and a control unit to control display of images on the liquid crystal panel, the control unit receiving the system dimming signal from the inverter unit and outputting a control dimming signal to the inverter unit, wherein the inverter unit adjusts luminance of the backlight unit using the control dimming signal input from the control unit.
