A German company and university have created a process which allows for the direct printing of electroluminescent layers onto three-dimensional components to provide a glowing result, and the researchers say these EL components could easily be adapted to safety applications in buildings in case of power failures. They add that they see applications for the process in displays and watches or even interior design. The process allows materials with flexible surfaces such as paper and plastic to be coated to make them glow, and Dr. Rainer Kling of the Light Technology Institute at KIT says this method can be adapted to any type of three-dimensional object, and it can be done at low cost.
