A backlight assembly for liquid crystal displays uses a clear sheet of plastic or UV friendly resin as a light-pipe (39) and has one or more fluorescent lamps (39) located in a cavity (51) along an edge of the sheet. The cavity (51) is coated with photo-luminescent phosphor (45). A quartz ultra-violet lamp (49) inside the cavity (51) is filled with Argon gas and a small amount of mercury to excite the phosphor (45) coated cavity (51) to fluoresce. The light energy generated is throughout the light-pipe (39), thereby providing much brighter displays than possible with prior art light-pipe backlight assemblies.
