A team from Fraunhofer Institute for Applied Polymer Research has developed a way to print organic light-emitting diodes to bring to reality next generation consumer electronics and solar cells. Curved monitors, flashing clothing, fluorescent wallpaper and flexible solar cells are soon to become reality./

Time is slowly running out for bulky TV sets, boxy neon signs and the square-edged backlit displays we all know from shops and airports. It won't be long before families gathering together to watch TV at home will be calling out: "Unroll the screen, dear, the film's about to start!" And members of the public may soon encounter screens everywhere they go, as almost any surface can be made into a display. "These may just be ideas at the moment, but they have every chance of becoming reality," said Armin Wedel, head of division at the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam-Golm. The first curved screens were on display at this year's consumer electronics trade show (IFA) in Berlin. The technology behind it all? OLEDs: flexible, organic light-emitting diodes.

But the potential offered by this technology extends beyond screens and displays for consumer electronics, according to Wedel. He believes OLEDs are also ideally suited to all kinds of lighting and to digital signage applications, that is to say, advertising and information systems such as electronic posters, advertisements, large image projections, road signs and traffic management systems. The scientists worked together with mechanical engineering company MBRAUN to develop a production facility able to create OLEDs as well as organic solar cells on an industrial scale. The innovative part is that it is now possible to print OLEDs and solar cells from solutions containing luminescent organic molecules and absorptive molecules respectively, which makes printing them onto a carrier film very straightforward. Usually, printing them involves vaporizing small molecules in a high vacuum, making it a very expensive process.
