Backlight Light assembly function

- Nov 22, 2017 -

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.
