发明名称 Method and device for driving CCFL circuit
摘要 A driving device for a CCFL circuit comprising at least one CCFL is provided. The driving device comprising at least one heating device controlling the temperature of the CCFL, a power supply outputting a first voltage, and a switching device having a first input terminal receiving the first voltage and a first and second output terminal; wherein the first output terminal is coupled to the CCFL circuit outputting a second voltage when the first voltage is higher than a first level, and the second output terminal is coupled to the heating device outputting a third voltage when the first voltage is lower than the first level. The driving device further comprises a controller controlling the power supply to output the first voltage higher than the first level to lighting up the CCFL, and lower than the first level to control the temperature of the CCFL.
