BLU Light Sources

• In LCD TVs:– CCFL – Cold Cathode Fluorescent Lamps

• LCD televisions produced a black and colored image by selectively filtering a white light. Conventionally, the light is typically provided by a series of CCFLs at the back of the screen.

– LED – Light Emitting Diodes• An LED-backlight LCD television is an LCD TV that uses LED backlighting instead of the CCFLs. It

is not a true LED display but is called "LED TV" by some manufacturers.

• In Advertising light boxes:– Fluorescent tubes - Conventional– LED – Latest trend
