Inverter circuit, backlight assembly and liquid crystal display with the same

A backlight assembly comprising:

• an even number of cold cathode fluorescent lamps disposed in one direction;
• a first electrode supplying a first voltage having a polarity to even-numbered cold cathode fluorescent lamps among the cold cathode fluorescent lamps;
• a second electrode supplying a second voltage having an opposite polarity to the first voltage to odd-numbered cold cathode fluorescent lamps among the cold cathode fluorescent lamps;
• and
• a balance circuit controlling currents flowing through the cold cathode fluorescent lamps,
• wherein the cold cathode fluorescent lamps are halved into a first group higher in temperature and a second group lower in temperature than the first group, and the balance circuit comprises:
• a plurality of primary coils directly connected to the lamps, at least one primary coil of the plurality of primary coils is directly connected between a cold cathode fluorescent lamp at a highest position of the first group and a cold cathode fluorescent lamp at a lowest position of the second group;
• and
• a plurality of secondary coils corresponding to the primary coils and connected to each other to form a loop.
