Scientists from Chalmers University of Technology in Gothenburg is developing an thin electronic paper containing pixels of the primary colors red–green–blue (RGB) that give the same reflectivity and contrast as ink produced by an ordinary printer. This in contrast to LED-displays makes it work very well in bright light. One of the research team members, accociate Professor Andreas B. Dahlin, said “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.” At the same time, it needs ten times less energy than a Kindle tablet. The ultra thin electronic paper is not yet ready for application, both because further research is required and also the manufacturing is currently too expensive since the material includes both silver and gold. But it has great potential to improve the functionality and experience of eBooks, as well as great potential of replacing traditional signs and information screens with more interactive screens.
