Multiple output DC/DC voltage converter and liquid crystal display using thereof

A liquid crystal display comprising:

• a liquid crystal display panel which has a plurality of pixels arranged in a matrix type in areas determined by a plurality of gate lines and a plurality of data lines crossing the gate lines;
• a gate driver which applies a gate on voltage to one of the gate lines sequentially thereby scanning the pixels in the liquid crystal display panel by a row;
• a source driver which receives a plurality of gray voltages and a video signal and selects the gray voltage corresponding to the video signal and applies the selected gray voltage to the data lines of the liquid crystal display panel;
• a gray voltage generator which generates a plurality of the gray voltages from data supply voltage and provides the gray voltages to the source driver;
• and
• a multiple output DC/DC converter which induces a transformer having a primary coil and at least one secondary coil that are coupled to one another by magnetic induction, receives a DC input voltage and generates main supply voltage from the primary coil of the transformer and at least two more auxiliary supply voltages from the at least one secondary coil of the transformer wherein, the main supply voltage is used as the data supply voltage and the auxiliary supply voltages are used as the gate on voltage and a gate off voltage.
