Backlight Light assembly function
Oscillator: Generates 60-100khz oscillating square wave signals.
Power amplification: The signal generated by the oscillator to enlarge to a sufficient point to light the power of the lamp.
High-voltage output: the power amplification signal to boost and convert to sine wave output, light CCFL lamp.
Protection detection: On the back plate output voltage and CCFL lamp working current, working status to detect, if there is an exception, control oscillator stop output, enter the protection state.
