Company also exhibits novel all-PHOLED white OLED lighting panel prototypes with innovative design elements for lighting products SID Display Week 2011 EWING, N.J.--(BUSINESS WIRE)--Universal Display Corporation (NASDAQ: PANL), enabling energy-efficient displays and lighting with its UniversalPHOLED® technology and materials, announced record-breaking performance of the company’s white OLED lighting technology at the 2011 Society for Information Display (SID) International Symposium, Seminar, and Exhibition being held from May 15 - 20, 2011. The company has developed a warm-white, all-phosphorescent OLED lighting panel with a power efficacy of 58 lumens per Watt (lm/W) and a record-breaking 30,000 hours of operating lifetime (to 70 percent of initial luminance). Based, in part, on the company’s new light blue UniversalPHOLED materials system, this represents a three times improvement in operating lifetime over results presented this time last year. The company is also exhibiting a series of white OLED lighting panel designs at booth #1212 at the Los Angeles Convention Center in Los Angeles, CA from May 17 - 19. The panels illustrate a number of novel design elements, including transparency and flexibility, for white OLED lighting products (see attached photo). Dr. Peter A. Levermore, Research Scientist at Universal Display, will present the advances in a paper titled, ‘Phosphorescent OLEDs: Enabling Solid-State Lighting with Lower Temperature and Longer Lifetime’, on Friday at 11:00 a.m. in Room 408B. In his paper, Dr. Levermore will describe two high performance, all-phosphorescent OLED lighting panels, 15 cm x 15 cm in size. In addition to the company’s enhanced light blue PHOLED materials system, the lighting panels use advances in OLED panel layout to achieve better uniformity. Combined with the lower operating temperatures afforded by the all-PHOLED material system, the panels achieved a three times greater operating lifetime compared to similar panels introduced last year. The first warm-white OLED panel, with a power efficacy of 58 lm/W, a color rendering index (CRI) of 83 and a correlated color temperature (CCT) of 2,580K, achieved a record-breaking 30,000 hours of operating lifetime to 70 percent of an initial luminance at 1,000 cd/m2. Results from the second panel design are similarly impressive. With a CRI of 82 and a CCT of 2,950K, the second panel demonstrates a record-breaking 62 lm/W with an operating lifetime of 18,000 hours to 70 percent of initial luminance at 1,000 cd/m2. It has been estimated that by 2016, solid-state lighting, including white OLEDs, could generate well over $20 billion in worldwide savings of electricity costs and could save over nine million metric tons of carbon emissions from the U.S. alone. Funded in part by the U.S. Department of Energy, these new white OLED panel performance advances now meet a variety of niche performance targets and move white OLEDs closer to general lighting targets established by the U.S. DOE.
