Transparent and non-transparent OLED signage devices have been developed for automotive applications.
A German research association has released OLED displays for the automobile, medical and industrial markets. The unique signage devices which are based on transparent small-molecule and non-transparent polymer OLEDs, are the latest technologies to be developed by the CAR OLED (CARO) project.
The three year project aims to develop highly efficient and reliable OLED devices for customer-specific automotive displays as well as signage devices. With a total R&D budget of €10.2m, CARO is supported by the Federal Ministry of Education and Research with seven partners from industry and academia including Optrex Europe, Novaled and Fraunhofer.
Transparent OLED displays could be used as dual displays, which are a combination of LCD and superposed OLEDs, as well as for 3D displays and see-through devices. Such displays demonstrate new interesting applications from both a functional point of view and a design aspect.
The transparent device is a contour-cut small-molecule OLED (SM-OLED) display based on Novaled's highly efficient PIN-OLED. The orange-emitting segmented signage device exhibits a transparency in the range of 65%, which is said to be one of the highest obtained values for OLEDs.
The non-transparent polymer OLED signage device is also an orange-emitting display that has been developed as a non-transparent alternative.
