Abstract
An inverter circuit includes an inverter transformer to supply AC high voltages of opposite phases, and a plurality of balance transformers. The inverter transformer supplies AC high voltages of same phases to every n number of CCFLs, and the CCFLs are connected in series to primary windings of the balance transformers at every two CCFLs. Also, secondary windings of the balance transformers are connected in series to form a closed loop. Thus, an inverter circuit may realized for a large-sized backlight without increasing a number of the balance transformers.
