“The advances made by our team further demonstrate the potential for Universal Display’s OLED technologies and materials to deliver the performance required for energy-efficient OLED lighting,” said Steven V. Abramson, President and Chief Executive Officer of Universal Display. “We’ve made significant advances in our light blue PHOLED materials system, which has enhanced the white OLED lighting performance we are introducing this week at SID. Our team has also developed a number
of innovative design concepts to inspire the imaginations of lighting designers around the
world.”
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 at1,000 cd/m2.
It has been estimated that by2016, 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.
