Abstract: A method of winding a coil of a transformer in an inverter of a liquid crystal display including a bobbin wound with a coil and a core introduced into the bobbin, the method includes forming a coil winding part having no protrusion member at the bobbin so as to exclude an interference caused by the protrusion member from a path wound with the coil; and continuously winding the coil from one side of the coil winding part to another side thereof.

Abstract: A power supply for a liquid crystal display panel, comprising a booster generating unit for generating a power voltage by boosting a system voltage comprising at least one operational amplifier for generating a common voltage and a gamma reference voltage, the booster further comprising at least one capacitor, at least one inductor, and at least one resistance arranged outside an integrated circuit, a common voltage generating unit having at least one operational amplifier, at least one resistance and at least one capacitor, wherein the at least one operational amplifier is located within the integrated circuit, and a gamma voltage generating unit having at least one operational amplifier and a resistance network wherein the resistance network is located outside the integrated circuit.

Abstract: A driving circuit of an LCD device compensates a gamma voltage according to a peripheral environment so that exact picture images can be displayed. The driving circuit of the LCD device includes a memory dividing the peripheral environment into a plurality of modes and storing information of each mode, an environment sensor sensing variation of the peripheral environment, a controller selecting information of a mode corresponding to the resultant value sensed by the environment sensor, a digital variable resistor adjusting a resistance value to correspond to mode information selected by the controller, and a gamma voltage outputting unit outputting a plurality of gamma voltages corresponding to the adjusted resistance value.
