摘要： An exemplary backlight control circuit includes a load (250), an inverter circuit (230), a pulse width modulation integrated circuit (PWM IC) (210), a protecting circuit (270), and a feedback circuit (240). The load (250) includes two backlight lamps (251, 252) with first terminals (241). The PWM IC with a protecting output (215) is connected to the load via the inverter circuit. The protecting circuit has a reference voltage. The first feedback circuit is capable of outputting a voltage to the protecting circuit corresponding to the voltage detected from the first terminals. The protecting circuit is configured to control the PWM IC to stop outputting a backlight adjusting signal to the inverter circuit such that the inverter circuit stops driving the load when the output voltage is higher than the reference voltage of the protecting circuit.
