| description | An LCD(Liquid Crystal Display) device and an abnormal current detecting method are provided to determine the abnormality of a lamp through an inverter circuit with a simple structure, thereby simplifying the configuration of a circuit. A control unit(100) delivers an operating signal to a resonance circuit unit(200). According to the operating signal of the control unit, the resonance circuit unit outputs the resonance signal of current and voltage to operate each lamp. A current detection unit(400) detects voltage or current supplied to the lamp to feed the detected voltage or current to the control unit. The current detect inputs a pair of currents to one of output terminals of both ends of a lamp(500) and the other output terminal of output terminals of both ends of the other lamp(510) in order to perform the feedback to the control unit. |
