Company invents luminous paper that can be folded up

The innovative Lightpaper looks like paper, but illuminates when energized. Can be folded, printed and glued to any surface.

What would you do with a sheet of paper that could work as a lamp, emitting white and intense light? The American company called Rohinni is trying to find out.

Its engineers have created Lightpaper, an innovative material that looks like paper, but illuminates when energized. To manufacture it, the company mixed microscopic LEDs with a special white paint. these LEDs as small as a red blood cell in our blood.

The paint is applied to an electrically conductive surface. Then, this blade is covered by two other layers, one on each side. Just connect some source of electricity to the two surfaces. The electric current flowing between them causes the LEDs to light up.

Lightpaper is not suitable for digital device screens, as it can not display images. In addition, so far the engineers have not yet been able to make the LEDs look perfectly uniform. This causes irregularities in the light emitted.

Even so, this technology may have applications in signage and lighting. It can be used in logos printed on electronics and cars, for example.

Traffic signs would be much more visible at night if they were made of lightpaper. Cyclists could ride more safely in the dark if they wore clothing with bands of this material.

The innovative Lightpaper looks like paper, but illuminates when energized. Can be folded, printed and glued to any surface.

The company told FastCompany that it has been negotiating the practical use of Lightpaper with other companies. It is possible that the first commercial applications will appear by the middle of 2015.
