Several German companies are collaborating on a project called CARO (CAR-OLED). CARO is an R&D project which aims to develop OLEDs for automotive applications (displays and signage).

Two of the companies (Fraunhofer IPMS and Optrex) have developed a steering wheel with an integrated white circula OLED signage display. It shows car-manufacturer neutral functions. Because the OLED is so thin, the basic design of the steering wheel is not changed, including the embedded airbag. The OLED displays was made at the Fraunhofer IPMS pilot lines.
