Upon its official termination today, the European research project
OLED100.eu celebrates the achievement of important advancements in
bringing organic light-emitting diodes (OLEDs) closer to market
introduction in general lighting. Fifteen companies and research
institutes from six European countries have been working on this goal
since September 2008. During this period, not only technical issues
have been investigated and solved, also the acceptance levels and
preferences of end-users with respect to this novel lighting technology
have been studied. Moreover, the research consortium has developed a
large-area OLED luminaire that consists of nine 33 × 33 cm²
OLED tiles.
- The energy efficiency and lifetime of organic LEDs for large-area lighting applications has been increased
- A large-area OLED luminaire that has been developed within the project will be presented
With OLED100.eu the consortium has focused on the five goals:
- Increase of the luminous efficacy
- Increase of the lifetime
- Up-scaling of the light-emitting area
- Reducing manufacturing cost by optimized processes
- Measurement standardization based on application research
The most relevant results are:
- High efficiency OLEDs based on Novaled PIN OLED technology and
out-coupling materials showing 60 lm/W which are more efficient than
energy saving lamps
- Long lifetime OLEDs with Novaled knowhow, demonstrating 100,000 hours comparable to inorganic LED lifetime
- Perception case studies on taste and acceptance of OLEDs as light source
- Industrialisation
scenarios and cost calculation of manufacturing processes with an
emphasis on cost-efficient technologies like screen printing for
substrate structuring
- Work on standardisation of measurement
procedures for OLEDs, which now serve as basis for work of the
International Commission on Illumination CIE
Today OLED100.eu presents for the first time the large-area OLED
luminaire, which consists of nine 33 × 33 cm² OLED tiles
with an optimized luminance distribution for application in shop
lighting.
»The OLED100.eu research consortium has played a vital part in
ensuring that Europe will play a leading role in OLED technology for
lighting applications also in the future«, says Dr. Stefan
Grabowski, Senior Scientist at Philips Research Aachen and project
manager of OLED100.eu.
»The results of OLED100.eu will contribute to further increase
the acceptance of OLED technology«, comments Dr. Karsten
Diekmann, who is responsible for OLED product and application
development at OSRAM. »In the project we gained a better
understanding of end-user preferences, a better comparability through
standardized measurement procedures, and better OLEDs.«
Dr. Christian May, Head of Business Unit OLED Lighting, gets excited
about the project results: »The work to achieve the challenging
goals of the OLED 100.eu project brought us to a higher level of our
COMEDD pilot process line. We are really proud of the 33 x 33 cm²
large OLED panels, which are one of the largest worldwide and made at
our pilot process line.«
Similar to inorganic LEDs, OLEDs are semiconductor devices, which
convert current into light. While inorganic LEDs are point light
sources, OLEDs emit light over a large area. OLEDs consist of different
organic materials that are deposited on a substrate. The light emitting
area has a thickness of only about 400 nanometres, a hundred times
thinner than a human hair. In off-state, OLEDs can be either
mirror-like, neutral white or transparent.
About OLED100.euOLED100.eu an integrated European research project to accelerate the
development of organic light-emitting diode (OLED) technology in
Europe, was running from September 1, 2008 to August 31, 2011. With an
overall budget of 19.95 Mio € it received 12.5 Mio € funding
by the European Community's Seventh Framework Programme to contribute
in forming the technological basis for efficient OLED applications for
the general lighting industry in Europe.
