Plextronics announced today that its Plexcore® OC NQ ink is now available for limited sampling, with more broad availability expected in 2011. The non-aqueous-based Hole Injection Layer (HIL) ink augments the company’s existing aqueous-based HIL, and is geared specifically for solution processible phosphorescent OLED emitters. The
company also expects to introduce ink-jet (printable) inks for limited sampling early in 2011. This is a major step for large, and cheap OLED-Television panels end 2011.
Mary Boone, Director of Ink Business Development at Plextronics, said, “The ability to solution process OLEDs, especially displays, is a fundamental hurdle that the industry needs to overcome in order to more broadly commercialize OLED technology. The technology has advanced to the point where we are getting that much closer to fully solution-processed OLED devices, and new
materials such as our non-aqueous HIL are a key requirement in the transition from vapor to solution processing.” Boone added, “Plextronics prides itself on its platform approach to our product offerings. We offer both aqueous and non-aqueous inks so that customers can select the exact material that they need. Plextronics is the only company that is currently offering a full line of OLED HIL inks for a variety of solution emitters.”
Results at Universal Display
Early sampling of Plexcore® OC NQ assisted Universal Display Corporation to achieve low voltage and long lifetime in recent performance testing of their P2OLED™ solution-processed, phosphorescent OLED technology.
On October 13, Universal Display issued a press release announcing significant advances in the performance of its Universal P2OLED™ solution-processible, phosphorescent OLED material systems. Plextronics was the HIL provider, and its Plexcore® OC NQ ink helped UDC to achieve a lower operating voltage and a boost in lifetime over previously disclosed results.
The UDC results were announced by Dr. Kwang Ohk Cheon, Senior Research Scientist at Universal Display, during the 10th International Meeting on Information Display (IMID 2010), from October 11 to 15 in Korea.
During his talk, Dr. Cheon reported on a new green P2OLED system with 66 candelas per Ampere (cd/A) and 130,000 hours of operating lifetime to 50% of an initial luminance of 1000 nits – representing approximately a two times improvement in luminous efficiency and lifetime
over Universal Display’s results reported a year ago.
