Organic light-emitting diodes (OLED) are mainly known from televisions and smartphone displays. They can be used as lighting objects in car tail lights or lights. The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP (Dresden, Germany) as a partner for customer-specific OLED development and production is now presenting OLED elements that can be integrated into textiles at the Electronics System Integration Technology Conference ESTC 2018 from 18 – 21 September 2018 in Dresden.
OLED microdisplays are increasingly establishing themselves in consumer-ready wearables and data glasses. In order to meet the requirements for higher efficiency, higher contrast, and higher resolutions in these applications, Fraunhofer FEP (Dresden, Germany) scientists have developed a new micropatterning approach for OLEDs on silicon substrates. This might eliminate the use of colour filters and shadow masks in the future and allow full-colour displays to be developed by means of a new process. An increase in efficiency and considerably broader colour gamut have already been demonstrated in first experiments. The results will be presented at the Fraunhofer FEP booth and during the poster session at IMID 2018 in Busan, South Korea, on 29-31 August 2018.
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP (Dresden, Germany) has succeeded in developing a new technology for the production of ultra-smooth polymer films as part of the "OptiPerm" project. This project received funding from the European Union and the Saxony State Ministry of Economics, Labor and Transport. The technology, which was previously demonstrated on samples in A4 format, has now been successfully transferred to a roll-to-roll process with even higher surface quality. These results were presented for the first time at the AIMCAL conference in Munich, Germany in June 2018 by Dr Steffen Günther.
