Backlight Assembly Function

Oscillator: generate 60-100KHZ oscillating square wave signal.

Power Amplification: Amplify the signal generated by the oscillator to enough power to light the lamp.

High-voltage output: boost the power-amplified signal and convert it into a sine wave output to light up the CCFL lamp.

Protection detection: Detect the voltage output by the backlight panel and the working current and working state of the CCFL lamp. If there is an abnormality, the control oscillator stops the output and enters the protection state.
