Philips and Fraunhofer to co-develop a new process for OLED production

Philips and the Fraunhofer Institute for Laser Technology (ILT) will co-develop a new process for OLED production - which aims to make OLEDs bigger and cheaper. The idea is to use a mask with micrometer slits on the surface of the ITO electrode, and then deposit a thin-film of aluminum (or copper or sliver) metal. A laser is finally used to melt the metal - unto the slits in the mask. The result - very fine and thin conductor paths (up to 40 micrometers).

The Fraunhofer say that this has already been achieved in the lab, and the next stage is to commercialize this together with Philips. The process might be ready within two or three years.
