Design of Start Voltage Waveform for Driving Flat Fluorescent Lamp (FFL) LCD Backlight

  • Published : 2006.08.22

Abstract

Flat fluorescent lamp(FFL) is used as a light source for LCD TV backlight and is composed of many discharge channels but each channel may not be turned on simultatneouly especially at cold temperature. The simultaneous start of each lamp channels of FFL was accomplished by driving FFL with specially designed voltage and currnet waveforms without sacrificing the inverter efficency.
