Apparatus for driving backlight of liquid crystal display

摘要

This invention relates to a backlight driving apparatus of a liquid crystal display device, and more particularly to a backlight driving apparatus of a liquid crystal display device that includes: first and second transformers that boost an AC voltage to a boosted AC voltage that is supplied to a U-shaped lamp; and a virtual ground fixing device that causes a virtual ground of the U-shaped lamp to be fixed at the center of a bent part of the U-shaped lamp by causing the boosted AC voltage that is output from the first and second transformers to be identical in size.
