Why use LED backlight？A few days ago in the IFA 2008 hosted in Berlin，many of the branded TV manufacturers introduced LED-backlighted TVs(LED TV)，aimed at the top layer of customers. Some leading manufacturers such as Sony and Samsung already introduced LED TV in 2006，but with the costs of LED have decreased and the LED technology has progressed rapidly, LED TV has moved toward a real product rather than just a demonstration of technology.

Recently, Luminus Devices and Everlight have each announced that their LEDs are powering new types of projectors. Luminus LEDs used in Samsung, LG projectors, Everlight starts shipping LEDs for micro projectors.
