Bendable electronic paper shows full colour scale

15. 10. 2016 | Chalmers University of Technology | www.chalmers.se

Researchers at Chalmers University of Technology have developed the basis for a new electronic paper that is less than a micrometre thin, flexible and giving all the colours that a regular LED display does, but still needs ten times less energy than a Kindle tablet.

When researchers from University of Technology were working on placing conductive polymers on nanostructures they discovered that the combination would be perfectly suited to creating electronic displays as thin as paper. A year later the results were ready for publication. A material that is less than a micrometre thin, flexible and giving all the colours that a standard LED display does while needing ten times less energy than a Kindle tablet.

Special flexible electronic paper

The ‘paper’ is similar to the Kindle tablet. It isn’t lit up like a standard display, but rather reflects the external light which illuminates it. Therefore it works very well where there is bright light, such as out in the sun, in contrast to standard LED displays that work best in darkness. At the same time it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.
