EU project IMOLA starts R&D on intelligent OLED lighting

Leuven, Belgium-based research institute Imec and its project partners are also pursuing flexible OLED structures by launching the Intelligent light Management for OLED on foil Applications (IMOLA) project as part of the EU’s 7th framework program for ICT (FP7). The project’s goal is to make large-area, OLED-based lighting modules with built-in intelligent light management.

Such flexible lighting systems target high-value-added applications including energy-efficient wall, ceiling and car dome lighting, where the light intensity can be adjusted intelligently, i.e. according to the time of the day or weather conditions.

The IMOLA project is designed to address the R&D challenges that currently keep large-area flexible OLED lighting from commercialization. Focus areas will include driver electronics, power distribution, integration and miniaturization, as well as sensor development and intelligence application. One IMOLA project goal is to help to create a common OLED infrastructure on a European scale.

The IMOLA consortium includes several industrial and academic partners. In addition to Imec, the project coordinator, the partners include TNO/Holst Centre (Netherlands), Philips Technologie (Germany), NXP Semiconductors (Netherlands, Belgium), Hanita Coatings RCA (Israel), Henkel Electronic Materials (Belgium), Centro Ricerche Plast-optica (Italy), and the FER department of the University of Zagreb (Croatia). 

NanoMarkets report forecasts substantial growth in OLED materials

Analysts for NanoMarkets have projected that 2014 will be the year that OLED lighting begins to generate significant revenues for suppliers of OLED lighting materials. NanoMarkets, a market research firm based in Glen Allen, VA, has announced the release of its latest market report entitled, “OLED lighting materials markets: 2012.” In 2015, the analysts expect the total market for OLED lighting materials to reach $1 billion.

The report contains volume and revenue forecasts for materials used for OLED lighting, broken out by material type and functionality in the OLED stack, as well as by OLED fabrication method – solution processing vs. vapor deposition, and small molecules vs. polymeric materials. NanoMarkets estimates that revenues from emissive layer materials are expected to top $375 million by 2015, and over 90% of this will come from sales of vapor-deposited small-molecule materials.

The report also looks at the strategies of OLED lighting manufacturers including Philips, Osram, Lumiotec, and Visionox.

OSA publishes issue focusing on OLED research

The Optical Society (OSA) has published a "Focus issue on OLEDs" in Energy Express, a bi-monthly supplement to its journal Optics Express. The aim of the collection of papers, accessible online at www.opticsinfobase.org/ee, is to highlight recent breakthroughs in OLED technology.

“The latest advances reflected in this focus issue are truly exceptional and will prove to be invaluable to advancements in lighting and display technology,” said Norbert Koch of the Institute of Physics, Humbolt University in Germany, and one of the organizers of the issue.

The supplement highlights reasons why top-emitting OLEDs are beneficial for lighting and display applications, methods for improving the outcoupling efficiency in OLEDs and how to optimize the optical path in the devices.
