Abstract

A controlling device and method of cold cathode fluorescent lamp with impulse width capable of automatically tracking and adjusting the job resonance frequency, which utilizes impulse width variation of job resonance frequency to track and adjust luminance, which simultaneously can be combined with frequency tracking or impact factor variation, or both, to achieve hi-efficiency driving of cold cathode fluorescent lamp and adjustment of luminance.
