Abstract: An electronic device adapted for adjusting a light effect of a CCFL is provided. The electronic device is electronically connected to the CCFL. The electronic device comprises a PWM controller configured to receive at least a digital signal and to output a specific-frequency reference signal according to the digital signal, a driver electronically connected to the PWM controller and configured to output a first voltage signal according to the specific-frequency reference signal, and a transformer electronically connected to the driver and the CCFL. The transformer amplifies the first voltage signal to generate a second voltage signal and sends the second voltage signal to the CCFL. A light effect is generated by the CCFL according to the second voltage signal.
