Soon, a roll-up TV screen that can be carried in your pocket!

A new technology developed by British scientists has brought the dream of television screens that can be rolled up and carried in a pocket closer to reality.

The researchers have developed a new form of light-emitting crystals, known as quantum dots, which can be used to produce ultra-thin television sets, the Sydney Morning Herald reported.

The tiny crystals, 100,000 times thinner than a human hair, can be printed on flexible plastic sheets to produce a paper-thin display, or on to wallpaper to create giant room-size

screens.

According to Michael Edelman, the chief executive of Nanoco, a spin-out company set up by the scientists behind the technology at Manchester University, the firm was working with 'major Asian electronics companies'.

It is believed that Sony, Sharp, Samsung and LG are working on the quantum dot television technology.
