Universal Display Announces Blue Phosphorescent OLED Device
Business Editors/Hi-Tech Writers
EWING, N.J.--(BUSINESS WIRE)--April 24, 2001--
New Device Establishes Core of High Efficiency Red, Green and Blue
Phosphorescent Materials for Full-Color Flat Panel Displays
Universal Display Corporation (UDC) (Nasdaq:PANL PHLX:PNL)
announced today that the company and its research partners at
Princeton University, and the University of Southern California have
invented what they believe to be the world's first efficient
phosphorescent blue OLED(Organic Light Emitting Device).
The blue OLED, in combination with the red and green
phosphorescent OLEDs already developed by UDC and its partners,
establish the core of primary colors and provides a promising advance
in opening up the full color, active matrix OLED display market.
According to Steven V. Abramson, president of UDC, "This
demonstration of an efficient blue phosphorescent device is an
extraordinary accomplishment by our scientists at UDC and our partners
at Princeton, USC and PPG Industries. This development can accelerate
the market penetration of our OLED technology for a number of product
applications ranging from advanced "3G" cell phones and other high
resolution portable products to television monitors."
Dr. Mark Thompson of the University of Southern California, a
principal inventor of the phosphorescent material system and a member
of UDC's Scientific Advisory Board said that phosphorescent materials
can be up to four times more efficient than conventional fluorescent
materials for OLEDs. "Efficiency is critical for long battery life for
portable display applications, and longer lifetimes for video monitor
applications."
He added that, the new device was a fluorinated iridium
organometallic complex and has been named "Firpic". It has a luminous
efficiency of approximately 12 cd/A, which is more efficient than
conventional fluorescent materials. Initial lifetime is a few hundred
hours, which is longer than UDC's phosphorescent green OLED when it
was first invented last year. The phosphorescent green OLED is
currently exhibiting lifetimes exceeding 10,000 hours.
Dr. Stephen Forrest of Princeton University, a member of UDC's
Scientific Advisory Board and whose innovative OLED work has been
fundamental to UDC's success noted: "In just a few short years the
conventional wisdom seems to have gone from thinking that the use of
phosphorescent materials in OLEDs was impossible, to now believing
that they are essential, as reflected by the recent announcement with
Sony Corporation."
UDC recently announced a Joint Development Agreement with Sony
Corporation focusing on the use of OLEDs in large area video monitors. |
