Universal Display Corporation, an innovator behind today's and tomorrow's displays and lighting through its Universal PHOLED(TM) phosphorescent OLED technology, announced today that the Company will discuss significant advances in its Universal WOLED(TM) white OLED technology on Friday, May 23 at the Society for Information Display (SID) 2008 International Symposium, Seminar and Exhibition in Los Angeles, CA.
Universal Display's Dr. Brian W. D'Andrade, Senior Scientist, will present the white OLED advances at the 9 A.M. PT White OLED I session in a paper titled “Extremely Long Lived Phosphorescent Organic Light Emitting Device with Minimum Organic Materials.” In his presentation, to be held in Concourse Hall 152, Dr. D'Andrade will describe a new simplified WOLED architecture that represents an important milestone toward the achievement of cost-effective OLEDs for lighting applications. Offering a warm white color with CIE coordinates of (0.45, 0.46) and 30 lumens per Watt (with outcoupling), this WOLED device boasts an extremely long operating lifetime, exceeding 200,000 hours at 1,000 cd/m2, and may be suitable for a variety of entry lighting products.
Dr. D'Andrade will also report on a new white OLED with record-breaking power efficacy of 72 lumens per Watt. Both devices use transport and injection materials provided by Universal Display's collaboration partner, LG Chem.
“I am delighted by the progress that our research team continues to make in white OLED technology development. Combining the high-efficiency performance of our Universal PHOLED technology with novel white OLED device structures is critical for making WOLEDs a viable technology for a variety of lighting applications,” said Steven V. Abramson, President and Chief Executive Officer of Universal Display. “Demonstration of these key milestones in lifetime, power efficiency and cost effectiveness has, indeed, moved us closer to making WOLEDs a commercial reality.”
This work was funded, in part, by the U.S. Department of Energy (DOE) through its Small Business Innovation Research (SBIR) program. Under the SBIR program and the Solid State Lighting Initiative, the DOE is working to accelerate advances in OLEDs as an energy-efficient, solid-state lighting technology. The DOE views OLEDs as “a pivotal emerging technology that promises to fundamentally alter lighting in the future.” Through the use of Universal Display's PHOLED technology, WOLEDs have the potential to meet the DOE's future performance targets, including a power efficiency of 150 lumens per Watt, in an exciting new thin form factor.
