INVERTER CIRCUIT, BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY WITH THE SAME

摘要

An inverter circuit, a backlight assembly and a liquid crystal display include first and second electrodes and a balance circuit. The first and second electrodes supply a voltage of opposite polarities, respectively, among an even number of cold cathode fluorescent lamps (CCFLs) disposed in one direction. The first and second electrodes supply the voltage of opposite polarities to even-numbered CCFLs and odd-numbered CCFLs, respectively. The balance circuit controls currents flowing through the CCFLs. The CCFLs are halved into a first group higher in temperature and a second group lower in temperature than the first group. The balance circuit includes primary coils directly connected between at least one CCFL of the first group and at least one CCFL of the second group and secondary coils corresponding to the primary coils that are connected to each other to form a loop.
