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.

Michael Edelman, chief executive of Nanoco, a spin out company set up by the scientists behind the technology at Manchester University, said: "We are working with some major Asian electronics companies. The first products we are expecting to come to market using quantum dots will be the next generation of flat-screen televisions.  ...

Professor Paul O'Brien, an inorganic materials chemist at the University of Manchester who helped top develop the quantum dot technology, said: "By altering the size of the crystals we are able to change the colour they produce. ...
