Just found an interesting article http://www.vnunet.com/vnunet/news/2144459/lightbulbs
This discovery could herald a new and efficient backlight source for LCD displays.
Quantumn Dots. when excited (By shining UV on them or by passing current through them) they emmit white light!. Until now white light from LED's has only been possible by combining Red Green and Blue light. This discovery should make most other white light sources obsolete, inc the common incandescent light bulb.
I hope some of you find this interesting.
