Patent ID: 7436133

Claim:
An improved LCD back light panel lamp connection structure, comprising: a plurality of cold cathode fluorescent lamps grouped into modules, with each module having a plurality of physically adjacent lamps, where physically adjacent lamps have no intervening lamps of other modules located therebetween, each of said lamps having a high voltage end at a first voltage and a feedback end at a second voltage, said lamps being arranged in parallel in a first direction forming a row in a second direction perpendicular to the first direction, the lamps in a given module having high voltage ends on the same side of the row, the high voltage ends and the feedback ends of adjacent modules being reversed, so that ends of modules on each side of said row alternate between high voltage ends and feedback ends; and return boards provided on opposite sides of said row, each return board being connected to feedback ends of half of the modules which are closer to the return board than the other half of the modules, and the return boards being connected to first and second terminals of a PWM control unit.
