Filed: 2007-03-29
Abstract: A backlight inverter and an LCD device using the same are provided to delay the phases of output voltages of a transformer of which the phases are inverted each other to detect the generation of an arc, thereby preventing the backlight inverter from being damaged by the generation of the arc. A transformer raises an input voltage at a winding ratio of a first winding coil and a second winding coil and outputs a first voltage and a second voltage. A protection level signal generator(138) delays the phases of the first voltage or the second voltage, adds the amplitude of the phases of each other, and generates a protection level signal. An arc state detecting unit(136) compares the protection level signal and a reference voltage to generate a detection signal. A driving control unit(132) controls a supply of the input voltage provided to the transformer in response to the detection signal. A backlight inverter(130) sets the delay of the phases so that the maximum value of the protection level signal can be greater than the reference voltage in response to additional phase delay caused by the disconnection of the transformer.
