- Red phosphorescent emitter functions optimally with Novaled’s
proprietary technology for highly power-efficient OLEDs
- Delivers lifetime of 50,000 hours at initial brightness of 1,000 cd/m2
- Supports market trend toward high-performance, low-voltage OLED devices
Ciba has developed a deep red phosphorescent OLED emitter that functions
optimally in combination with the Novaled PIN OLED™
technology, delivering a lifetime of 50,000 hours at an initial
brightness of 1,000 cd/m2.
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™ 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™ 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 www.novaled.com.
