Arrays of thousands of tiny 'super prisms' controlled by robotic muscles could bring real colour to TV screens for the first time, scientists say.

The devices, known as electrically tunable diffraction gratings, have been built by researchers in Switzerland.

They manipulate light to reproduce the full spectrum of colours on screen, impossible using existing technology.

The team say the devices could also be used to make computer displays with the same resolution as high-end LCDs.

'Today's displays can only reproduce a limited range of colours,' said Manuel Aschwanden of the Swiss Federal Institute of Technology in Zurich, and one of the team behind the work.
