Fraunhofer's COMEDD and POG Präzisionsoptik Gera have co-developed OLED structures coated in the range of micrometers at opaque or transparent glass substrates. This technology can be used in complex optical and opto-electronical systems in a range of applications (medical, laser, aerospace, telescopes, microscopes and even sports optics). Basically these are transparent optical devices with self-emitting figures, points or lines;

The best technology used today to achieve the same effect uses prisms. The advantage the new design is that the active luminous area is integrated directly into the glass substrate which results in a better field of view, and the whole system is much more simple - and hopefully will result in cheaper designs.
