Universal Display and Its Research Partners Receive Key Patent for Power Efficient Phosphorescent 'PHOLEDs'
EWING, N.J.--(BUSINESS WIRE)--Oct. 23, 2001-- Universal Display Corporation (NASDAQ:PANL; PHLX:PNL), a leading developer of flat panel display technology, announced today that its research partners, Princeton University and the University of Southern California (USC), have been issued a key patent in the field of OLED (Organic Light Emitting Device) technology.
The patent, OLEDs Doped with Phosphorescent Compounds, U.S. patent number 6,303,238, grants Universal Display Corporation (UDC) a broad, fundamental position in the use of phosphorescent dopants in OLEDs (PHOLEDs). Phosphorescent dopants are important because they can improve OLED power efficiency, a critical performance parameter in flat panel displays, by up to four times over conventional OLEDs. Universal Display has the exclusive worldwide rights to this patent, which encompasses 63 claims.
According to the Company, researchers began using fluorescent dopants in OLEDs in the mid-1980s. A few years ago, UDC's research partners at Princeton University and USC discovered that phosphorescent dopants could be used in OLEDs to provide significant advances in performance, i.e., power efficiency, lifetime, and color tunability. Since that time, UDC and its partners have developed OLEDs using these phosphorescent dopants - demonstrating world-record power efficiencies in all three primary colors. UDC's proprietary phosphorescent materials can enable its manufacturing partners to produce OLED displays with significant performance advantages over conventional OLEDs as well as over today's market-dominant liquid crystal displays (LCDs) for products that range from cellular telephones to television monitors.
According to Steven V. Abramson, President of Universal Display Corporation, ``The importance of power efficiency cannot be underestimated in today's mobile, battery-powered, and visually-driven products. With our team's advances, we are building the technology to provide OLED displays with the performance that consumers demand in handheld electronics, laptop computers, and television monitors.''
To this end, Universal Display Corporation has a joint development agreement with Sony Corporation focused on the television monitor market. More recently, the Company announced a joint development agreement with Samsung SDI for portable displays. Separately, these development agreements seek to integrate UDC's high-efficiency phosphorescent OLED materials into active matrix OLED displays that each company will manufacture. OLED technology is widely considered to be a transformational technology for flat panel displays. Abramson said, ``Our alliances with two of the world's leading electronics manufacturers underscores the significance of this technology and signals that this new generation of flat panel display technology is quickly becoming a commercial reality to address the growing markets for electronic displays.''... |
