UDC Awarded Patent for Ink-Jet Printing of OLEDs
EWING, N.J. - Jan. 30, 2006 - Universal Display Corporation (UDC), the Company that's lighting the way in developing and commercializing OLED technology for flat panel displays, lighting and other opto-electronics with its proprietary phosphorescent OLED (PHOLED) technology, announced today that it has been awarded a significant patent covering ink-jet printing of phosphorescent OLED displays, US Patent No. 6,982,179, titled "Structure and Method of Fabricating Organic Devices".
Through its continued innovation, Universal Display is developing new technologies for the direct printing of PHOLED materials by ink-jet printing and other low-cost manufacturing techniques. The Company's broad patent capitalizes on ink-jet printing's potential to become a low-cost manufacturing process, opening an additional avenue for the future mass production of large-area OLED displays.
"This PHOLED ink-jet printing patent provides another option for OLED manufacturers in choosing how to produce displays using our proprietary phosphorescent OLED technology," said Steven V. Abramson, President and Chief Operating Officer of Universal Display Corporation. "The patent is a further demonstration of the breadth and depth of Universal Display's PHOLED technology, which is widely recognized as critical for OLED displays - from small, where power efficiency is critical, to large, where power efficiency equates to less heat generation."
PHOLED technology and materials have already been recognized for offering superior display performance when used in conventional vacuum thermal evaporation (VTE) equipment. Today, substantially all OLED displays are made by VTE. Conventional thinking has been that small-molecular (non-polymeric) OLED materials were not amenable to ink-jet printing. Through this invention, Universal Display has shown an innovative way for its small-molecule PHOLED materials to be ink-jet printable, creating an opportunity to combine the low-cost potential of ink-jet printing with the superior performance of the Company's proprietary PHOLED materials and technology.
Universal Display has pioneered PHOLED technology that is up to four times more efficient than conventional OLED technology. Power efficiency is a key metric to the near-term commercialization of OLED displays in portable electronics, as well as the development of OLED televisions and larger screen displays. In addition to superior power efficiency, PHOLEDs offer excellent color quality and long operating lifetime.
OLEDs, which emit light when electric current is applied, also have significant advantages over liquid crystal displays (LCDs) because they do not need bulky LCD backlights. As a result, OLED displays are thinner, lighter, more efficient, and can be applied to a wide variety of substrates and shapes. They also provide more vivid images with broader viewing angles and superior video-rate performance as compared to standard LCDs.
The Company's technology is currently being evaluated for commercial production by leading electronic display manufacturers for active-matrix OLED displays in 2006 and beyond.
