OLED lighting for use as transparent car roof
BASF SE based in Germany and Royal Philips Electronics of the Netherlands have achieved a practical breakthrough in the development of OLED (Organic Light Emitting Diode) technology that allows it to be integrated in car roofs. When switched off the OLEDs are transparent, allowing a clear view outside the vehicle. When switched on they provide light only within the vehicle.
Additionally the transparent OLED sandwich structure can be combined with equally transparent solar cells. “This combination allows the driver to enjoy a unique open-space feeling while it generates electricity during the day and pleasantly suffuses the interior with the warm light of the transparent, highly efficient OLEDs at night,” says Dr Felix Görth, head of Organic Light-Emitting Diodes and Organic Photovoltaics at BASF Future Business GmbH.
