<p><P>PROBLEM TO BE SOLVED: To provide a multi-lamp backlight system in which driving currents of the lamps are automatically balanced with only a single transformer. <P>SOLUTION: This multi-lamp backlight system comprises: a magnetic core; a first coil set wrapped around the core, to which a first AC voltage is applied; second and third coil sets wrapped around the core and respectively disposed on two sides of the first coil set, on which second and third AC voltages are induced by the first voltage signal applied to the first coil set respectively, wherein the numbers of coils of the second and third coil sets are substantially the same; and first and second lamps supplied with power by the second and third AC voltages, respectively. <P>COPYRIGHT: (C)2004,JPO</p> |
