ovaled has developed a highly power-efficient white OLED structure achieving 60 lm/W at capable of reaching
a very long lifetime of 100,000 hours at an initial brightness of 1,000 cd/m2
available fluorescent blue emitting material.
The high efficiency device also demonstrates a high color rendering index (CRI) of 87. A very broad light emission spectrum and good CIE color coordinates (0.470/0.429) were achieved, which is close to illu- minant A and inside the US Department of Energy (DOE) quadrangles meeting the DOE energy star color specifications.
For this OLED stack Novaled intentionally used a classical and commercially available fluorescent blue emitter material. The OLED power efficiency with such materials is usually much less than with phos- phorescent emitters, but due to the advantages of the Novaled PIN OLED®
technology and proprietary
materials a remarkably high value could be reached. The use of the fluorescent blue emitter material has several advantages. Beside the fact that it is commer- cially available, it allows very good device stability and guarantees a higher lifetime of OLED devices. Also, it enables a broad coverage of the complete visible colour range, resulting in the very high colour
while using commercially
rendering index value achieved by the OLED device. The OLED sample incorporates Novaled light ex- traction technology and dedicated material NET 61 thereby enhancing the efficiency and improving the angular dependence of emitted light. By meeting the standards for commercial lighting applications, Novaled’s new power-efficient white PIN OLEDs are already ideal for OLED lamps and luminaires for general and design lighting.
“Associating commercially available and robust fluo- rescent blue emitters with Novaled technology and materials leads to high OLED performances which meet major lighting market needs immediately“, says Gildas Sorin, CEO of Novaled AG. “Once phosphore- scent blue emitter materials become real commercial products our technology will allow for a further boost in OLED device efficiencies showing the way to ex- ceed above 100lm/w and long life time.”
Novaled’s manufacturing uses standard processes to produce the white PIN OLED device structures. Standard glass substrates with ITO, ordinary evapora- tion processes and simple outcoupling methods allow for an easy adoption to existing manufacturing lines and for a cost efficient volume production of such devices.
Furthermore, Novaled AG reinforces its support of Asian customers by opening a Representative Office in Korea, Seoul. Effective from July, 2011, Novaled sets up a Representative Office in Seoul, Korea. With this opening, the company confirms its commitment to the OLED industry in Asia. Novaled’s new Korean office will reinforce the service and support in the center of AMOLED display industry.
