Light Guide Plate Working PrincipleLight Guide Plate Working Principle
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
