Ciba Develops Long-Lifetime Phosphorescent Material for Novaled´s OLED Technology

Ciba has developed a deep red phosphorescent OLED emitter that
functions optimally in combination with the Novaled PIN OLED(TM)
technology, delivering a lifetime of 50,000 hours at an initial
brightness of 1,000 cd/sqm. The new material supports the market trend
toward high-performance, low-voltage OLED devices for display and
lighting applications.

"We want to provide the market with efficient phosphorescent
materials," says Rolf Drewes, Global Head of Business Line Electronic
Materials at Ciba. "In this project, we are developing the full color
range of emitters compatible with Novaled´s proprietary OLED
technology. Our deep red, the first to become commercially available,
offers customers not only long-lifetime performance but also excellent
thermal stability. Green and blue are now in progress."

"Phosphorescent emitter materials together with low-voltage
devices are mandatory for the future of the OLED industry, and Novaled
is very pleased to see a key industry player developing such
materials," adds Gildas Sorin, CEO of Novaled AG. "This deep red
phosphorescent material provides a long lifetime at a lowest operating
voltage of 3.3 V as well as good power efficiency of 8.1 lm/W, making
it suitable for displays as well as for completely new lighting
applications. OLED technology even has potential to surpass the
efficiency of energy-saving bulbs."

Made of thin organic material layers only a few nanometers thick,
OLEDs are semiconductors that emit light in a diffuse way to form an
area light source. In 2006, Ciba and Novaled entered an industrial
collaboration to create organic dopant and transport materials for the
Novaled PIN OLED(TM) technology, which enables highly power-efficient
OLED performance.

Novaled AG is a world-leading company in the OLED (organic
light-emitting diode) field specialized in high efficiency,
long-lifetime OLED structures and an expert in synthetic and
analytical chemistry. The company offers complete solutions to the
organic electronic markets, commercializing its Novaled PIN OLED(TM)
technology along with its proprietary OLED materials. Novaled has
developed long-term partnerships with major OLED players worldwide.
Based on more than 350 patents granted or pending, Novaled has a
strong IP position in OLED technology. For more information, visit
