Led by Philips Technologie GmbH in Germany, the OLED100.eu team which consists of partners from Belgium, Germany, France, the Netherlands, Austria and UK, has been working on OLEDs for the last three years.
The aims of the research were to boost the luminous efficacy, strengthen the lifetime, upscale the light-emitting area, optimise processes to slash production costs, and standardise measurement based on application research.
During the period, the team has achieved great breakthrough. Firstly, it developed a large-area OLED luminaire consisting of 9 OLED tiles of 33 x 33 square centimetres each.
Secondly, it succeeded in demonstrating high-efficiency OLEDs based on Novaled PIN OLED technology and out-coupling materials showing 60 lumens per watt (lm/W) which are more efficient than energy-saving lamps.
Thirdly, it also secured long-lifetime OLEDs with Novaled know-how, showing 100 000 hours comparable to inorganic LED lifetime. The researchers performed perception case studies on taste and acceptance of OLEDs as light source, and they carried out industrialisation scenarios and cost calculation of production processes with a particular focus on cost-efficient technologies like screen-printing for substrate structuring.
Apart from that, they succeeded in devising standardisation of measurement procedures for OLEDs, which currently serve as the basis for work of the International Commission on Illumination (CIE).
