A backlight driving system for a liquid crystal display device for simplifying a structure of an inverter circuit unit is provided to perform power consumption and visibility improvement through DCR driving and use a system circuit unit. A system circuit unit(100) generates dimming signal for source backlight control for emission control of the backlight and supplies the dimming signal to a control circuit unit(300) through an inverter circuit unit(200). According to the dimming signal for the backlight control which the inverter circuit part is provided from the control circuit unit, the radiation control of the back light is performed. The control circuit unit comprises the timing controller controlling the image display to the liquid crystal panel. |
