OSRAM Opto Semiconductors has set an important milestone in developing OLED technology. The OLED prototypes that OSRAM has developed as part of a research project are large transparent light sources only a few hundred micrometers thick.

Thanks to new technology these organic light emitting diodes do not need separate encapsulation and can be made incredibly thin in any layout.

The transparent test samples have a luminous area of 210 cm² and are already showing the enormous potential of OLED light sources.
