ArcelorMittal and Novaled Engaged in Joint OLED-Development

ArcelorMittal, the world's largest quality steel maker, and
Novaled, OLED (Organic Light Emitting Diode) technology and material
provider, have joined forces for a new OLED project. The partners are
developing top-emitting OLEDs on flexible substrates for signage and
lighting purposes since 2006.

By using ArcelorMittal's steel plates as substrates, remarkable
properties for bendable OLED applications can be achieved. Metallic
substrates offer several advantages. Compared to standard glass-sheets
they are more robust and durable and commonly produced by roll-to-roll
process. This production method can be adapted to a subsequent inline
process for OLED-deposition enabling high through-put manufacturing
with low tact time. In this collaboration Novaled contributes both its
broad technical experience with respect to highly efficient and stable
OLED device architectures as well as its material know-how for doped
transport layers.

"We are always looking for ways to innovate and develop new
application fields that add value to our steel products. We consider
OLEDs to be very promising" says Michel Beguin, General Manager of
ArcelorMittal's Industry Research Centre. "The Novaled technology
gives us the advantage of an efficient top inverted structure well
adapted to our metal substrate".

"RGB OLEDs have been processed directly on classical steel plates.
The striking results showed that the Novaled technology enables
standard steel foil acting as reflective bottom electrode" adds Jan
Blochwitz-Nimoth, CTO of Novaled. "We are very pleased to support
ArcelorMittal in its OLED developments on metal plates".

About OLEDs

OLEDs, unlike normal (inorganic) LEDs, incorporate organic
materials in thin layers generating light emission when electrical
power is applied. In contrast to LEDs, they are rather large-area
sources with low brightness that emit diffuse light in any colour.
They can be easily structured to show patterns of colour or
homogeneous white light. Currently OLEDs are mainly applied in small
display applications, e.g. mobile telephones, MP3 players or personal
digital assistants (PDAs). In the future, thanks to OLEDs' diffuse
emission character and slim/lightweight form, it will be easier for
people to create an adaptable lighting environment and to feel
comfortable in any mood. By combining colour with shape, organic LEDs
will also create a new way of decorating and personalizing people's
surroundings with light. OLEDs offer the potential to become even more
efficient as energy-saving bulbs. Once efficient OLEDs are available
at mass production costs, they can be used for a multitude of
applications in lighting.
