LCD back light panel lamp connecting structure
An improved LCD back light panel lamp connecting structure comprises at least one set of cold cathode fluorescent lamps (CCFL), each having its high voltage end and feedback end arranged alternately, and the feedback ends on both sides of the CCFL respectively coupled to two return boards. Such 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.
