    摘要: A light driver circuit device for synchronously driving a plurality of cold cathode fluorescent lamps (CCFLs) is provided. The light driver circuit device includes an inverter circuit board and a balance circuit board. The inverter circuit board has an inverter circuit coupled to a driving signal for outputting a driving voltage to drive the CCFLs synchronously. The balance circuit board and the inverter circuit board are installed separately, and the balance circuit board has a balance circuit coupled to a terminal of each CCFL and the inverter circuit. The CCFL driving architecture is designed to install the inverter circuit and the balance circuit individually, thus effectively reducing the space of the driving circuit and the total cost of the circuit design. Furthermore, the balance circuit board can balance the current in each CCFL effectively, and there is no limitation to where the balance circuit board can be disposed.
