The full colour 'skin screen' you can wear as clothing: Radical technology could let you alter your outfit instantly

  • Could be used to create clothing and camouflage that changes colour
  •  May also lead to paper thin rollable TV set and phone displays

It could allow soldiers to change the color and pattern of their camouflage instantly, and let indecisive dressers alter their clothing in a second.

Researchers have unveiled the first fully flexible colour screen, and say it if so flexible it can be worn.

They say the technology is based on a chameleon.

The team were able to create this iconic National Geographic photographic of an Afghan girl to demonstrate the colour-changing abilities of the display.

HOW IT WORKS

Traditional displays like those on a mobile phone require a light source, filters and a glass plates.

But animals like chameleons, octopuses and squids are born with thin, flexible, colour-changing displays that don't need a light source - their skin.

The new method doesn't need its own light source.

Rather, it reflects the ambient light around it.

A thin liquid crystal layer is sandwiched over a metallic nanostructure shaped like a microscopic egg carton that absorbs some light wavelengths and reflects others.

The colors reflected can be controlled by the voltage applied to the liquid crystal layer.

'All manmade displays - LCD, LED, CRT - are rigid, brittle and bulky.

But you look at an octopus, they can create color on the skin itself covering a complex body contour, and it's stretchable and flexible,' said Professor Debashis Chanda of the University of Central Florida, who developed the technique for creating the world's first full-color, flexible thin-film reflective display.

Chanda's research was inspired by nature, he said.

'That was the motivation: Can we take some inspiration from biology and create a skin-like display?'

The team is able to change the colour on an ultrathin nanostructured surface by applying voltage.
