Forget 3D, here comes the QD TV
Researchers have developed a new form of light-emitting crystals, known as quantum dots, which can be used to produce ultra-thin televisions. The tiny crystals, which are 100,000 times smaller than the width of a human hair, can be printed onto flexible plastic sheets to produce a paper-thin display that can be easily carried around, or even onto wallpaper to create giant room-size screens. The scientists hope the first quantum dot televisions - like current flat-screen TVs, but with improved colour and thinner displays - will be available in shops by the end of next year. A flexible version is expected to take at least three years to reach the market.
