Abstract: A backlight module control system includes a power supply, a first backlight sub-module, a second backlight sub-module, a first transformer and a second transformer. The power supply is utilized for providing an operating power to the backlight module control system. A primary side and a secondary side of the first transformer are respectively coupled to the power supply and a first node of the first backlight sub-module. A primary side of the second transformer is coupled to the power supply, and a secondary side of the second transformer is coupled to the secondary side of the second transformer and a first node of the second backlight sub-module.

Abstract: A backlight module includes a fluorescent lamp, an LED module, a controller, a lamp inverter, and an LED driver. The controller generates a first control signal and a second control signal according to a display signal. The lamp inverter drives the fluorescent lamp according to the first control signal. The LED driver drives the LED module according to the second control signal. The LED module is installed close to the fluorescent lamp for compensating the luminance of the fluorescent lamp when turning on and turning off.

Abstract: A scanning backlight source driving apparatus and a liquid crystal display using the same are provided, wherein the scanning backlight source driving apparatus includes a DC/AC inverter, N transformers, N switches, and a control circuit, where N is a natural number. The DC/AC inverter has a first output terminal and a second output terminal configured to output an AC voltage. Each transformer has a primary winding. Each switch electrically connects the first output terminal to the second output terminal through a corresponding one of the primary windings. The control circuit is configured to control periodic and temporary turn-on or turn-off on the switches in a predetermined sequence.
