are used as white-light sources to backlight liquid crystal displays (LCDs),
Cold Cathode Fluorescent Lamps (CCFLs) are sealed glass tubes filled with inert
gases. When a high voltage is placed across the tube, the gases ionize creating
ultraviolet (UV) light. The UV light, in turn, excites an inner coating of
phosphor, creating visible light, ..., pdf file |
