Innovation in the field of flat panel displays:
Universal Display Announces Blue Phosphorescent OLED Device, Tuesday April 24, 8:57 am Eastern Time
New Device Establishes Core of High Efficiency Red, Green and Blue Phosphorescent Materials for Full-Color Flat Panel Displays
EWING, N.J.--(BUSINESS WIRE)--April 24, 2001-- 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.
