Universal Display has more news for us at SID 2010. They have already announced the new light-blue light-blue phosphorescent OLED emitter system, suitable for both display and lighting applications. Today they are presenting an all-phosphorescent white OLED to address initial commercial niche white lighting applications
UDC is showing a 15cm x 15cm OLED lighting panel using the company’s highly-efficient phosphorescent OLED technology and materials. UDC believes that this panel is the most energy-efficient performance, at this scale, reported to date. This panel emits a warm-white light with a color rendering index (CRI) of 87 and a correlated color temperature (CCT) of 3055K. It also has a luminous efficacy of 50 lumens per Watt using an optical outcoupling treatment with a modest 1.5x enhancement factor. With an operating lifetime of approximately 10,000 hours to 70% of an initial luminance of 1,000 cd/m2, this panel performance has the potential to meet the requirements for a number of initial commercial niche OLED lighting applications, and is an important step toward white OLED panel performance that achieves Energy Star
targets.
UDC's research is funded in part by the U.S. Department of Energy
