LCD back light panel lamp connecting structure |
摘要 |
An improved LCD back light panel lamp connecting structure arranges a high voltage end and a feedback end of adjacent cold cathode fluorescent lamp (CCFL) modules alternately, and the feedback end of the CCFL is coupled to a single return board. The return board is 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.
