Abstract
A backlight driving circuit for an LCD device is disclosed, in which multiple high-voltage parts each having an inverter circuit are provided, and the plurality of high-voltage parts are dispersedly arranged at both rear sides of an LCD panel. The distribution of the high voltage parts obtains a uniform temperature dispersion in the LCD device, and the lifespan of the LCD is therefore enhanced.
