PURPOSE: A back light inverter is provided to reduce the manufacturing cost and improve the productivity by minimizing the circuit by configuring the arc protection circuit using a plurality of p channel transistors and n channel transistors. CONSTITUTION: An inverter driver(110) outputs the lamp driving signal according to the predetermined PWM control signal. A transformer(130) converts the lamp drive signal transmitted through the inverter driver and offer it to the lamp. An arc protection circuit part(150) outputs the surge related signal to an inverter controller(170). |
