Universal Display Scientists Announce Technology Advances in Phosphorescent OLED
Materials and Plastic OLED Displays at ICEL Conference Business Editors LOS ANGELES--(BUSINESS WIRE)--Sept. 6, 2001--Universal Display Corporation (NASDAQ:PANL; PHLX:PNL), a leading developer of flat panel display technology, presented two papers at the 3rd International Conference on Electroluminescence of Molecular Materials and Related Phenomena (ICEL) in Los Angeles, describing progress in the development of its high efficiency electrophosphorescent material system, and in its flexible plastic display technology program. Dr. Raymond Kwong, Senior UDC Scientist, in his paper titled "Long Lifetime Electrophosphorescent Devices", discussed the lifetimes of UDC's red and green emitting proprietary electrophosphorescent (PHOLEDtm) materials. He described a UDC green PHOLED with an efficiency of 21 cd/A that has a 10,000-hour lifetime, and two UDC red PHOLED's, one with an efficiency of 6.5 cd/A with a 3,000-hour lifetime, and another with an efficiency of 2.7 cd/A that has a lifetime of 100,000 hours. This latter device is the longest reported lifetime for an efficient red device that meets the NTSC red coordinates. UDC's PHOLED materials have shown record high efficiencies in red, green and blue OLED devices, and the red and green materials have now demonstrated lifetimes commensurate with commercial use. Dr. Michael Weaver, Senior UDC Scientist, in his paper titled "Plastic Video Displays Using OLEDs" demonstrated a high-efficiency red electrophosphorescent flexible plastic OLED video display. UDC had previously demonstrated the world's first high-efficiency electrophosphorescent green flexible plastic OLED video display at its Annual Meeting in June. These displays are 0.175 mm thick, contain 15,000 pixels at 80 dpi, have 256 levels of grey scale and show full motion video. Dr. Weaver also announced that UDC, together with its partners at Vitex Systems, Inc. and Batelle Pacific Northwest National Labs, had demonstrated 3000 hours of lifetime on a Flexible Glasstm barrier coated plastic substrate with a rigid lid, showing additional progress in the use of barrier coated plastic for use in flexible OLED (FOLEDtm) devices. Steven V. Abramson, President of Universal Display Corporation, said, "High efficiency PHOLED materials are one of the key ingredients for the success of OLEDs, and flexible plastic FOLED displays are an extraordinary opportunity for OLED technology. We are very proud of our team as it leads the way in developing and commercializing this transformational technology." |
