Universal Display Corporation (NASDAQ: PANL), an
innovator behind today’s and tomorrow’s displays and lighting through its Universal
PHOLED™ phosphorescent OLED technology, announced today that the Company will discuss
significant advances in its Universal WOLED™ 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. PST 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 costeffective
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.”
