The project LOIGB (LED and OLED integration into glass and plastic composites for the use in lighting systems for railway and further applications) has been successfully completed. The results will be presented at LOPEC 2015 (March 4th – 5th, 2015, Munich, hall B0, booth 230).
The objective of the joint project was the development and integration of large-area color variable OLED modules, whereby the light colors red, green and blue (RGB), which are required for the achievement of white mixed light, can be controlled separately.
Thus it is possible to generate any desired color, including white, with one and the same OLED module. The realization of large-area 3-color-variable OLED modules could be demonstrated in the project.
The OLED modules have a diameter of 55 mm with an active light area of 42 mm. They were encapsulated with a full thin film, which enables the lamination of OLED modules in glass composites.
For the first time worldwide a transparent 2-color variable OLED, which can show a color gradient from blue to white to yellow, will be demonstrated. This exhibit will be presented to the visitors of LOPEC 2015 at the Fraunhofer FEP booth.
A possible field of application could be its use as the light source in a laminated glass sheet which serves as baggage compartment in trains. The company SBF Spezialleuchten GmbH, the coordinator of the project, is working on such solutions.
“The possibilities for application of the results, which are achieved within the project, are extraordinarily versatile”, says project manager Jan Hesse. “In addition to the use in general lighting, e.g. in windows, wall elements or wallpapers, the color variable OLEDs are as well suitable for the interior vehicle lighting – especially for the ambient or accent lighting – in the automotive and rail vehicle industry.”
Besides, the aviation industry shows great interest in using this technology for ambient lighting within an aircraft cabin.
The results which were achieved in the project LOIGB provide a basis for further activities at Fraunhofer FEP. Currently, the scientists are working on the process development in order to achieve higher yield and reduce manufacturing costs as well as to realize the process transfer to a roll-to-roll system for flexible OLED. Moreover, the intuitive control of such lighting elements will become a priority. Compared to conventional light sources (on / off), the complex functionality (dimmability, color variation and dynamization through segments) requires new intuitive control possibilities. A simple control is absolutely necessary in order to achieve market acceptance for that innovative lighting technology.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
