1.1 Structure and priniple
  104PW191 inverter for LCD(Liquid crystal display) modules is composed of a DC/AC iversion circait,a luminance eontrlo circait and a boosting transforme.
  The DC/AC inversion circuit inverts a  direct current (DC) Power supply into an altar crrent （AC) by the center-tap transmitter circuit that used transstors.
The luminance control circuit can control the luminance of cold cahode lamps ofr LCD backlight unit.tothe high AC voltage.Also the high AC voltage is outputed from a secondary side of thebosting transformer.
