Abstract:
A lamp drive circuit used for driving a number of lamps is provided. The lamps are used in a backlight module. The backlight module is used for providing a light source when a liquid crystal display displays. The lamps are respectively electrically connected to a coil. The coils have the same number of turns and have the same magnetic circuit, so that the currents flowing through the lamps are balanced.
