Robert Heron: Quantum Dots to the rescue

Nanosys Quantum Dots

LCD TV manufacturers are experimenting with a semiconductor technology known as a quantum dot (QD) in order to expand the color capabilities and improve the efficiency of their products. QDs are crystalline structures that are engineered to emit a very pure and precisely colored light. The size of a QD crystal determines its color. Larger QD crystals produce a more reddish hue and smaller particles skew towards blue.
