ABSTRACT:
An improved LCD back light panel lamp connecting structure comprises cold cathode fluorescent lamps (CCFL), and adjacent CCFL modules having high voltage ends and feedback ends arranged alternately, and the feedback ends on both sides of the CCFLs respectively coupled to two return boards. The feedback end of the CCFL is coupled to a proximate return board, and the return board is disposed separately at both ends of the CCFLs. Two return boards are coupled to a pulse width modulation (PWM) control unit so that the two return boards feed back the current to the PWM control unit. The high voltage end of the CCFL is coupled to a transformer.
