Universal Display Corporation (NASDAQ:PANL), enabling energy-efficient displays and lighting with its UniversalPHOLED™ technology and materials, today will unveil a new light-blue phosphorescent OLED emitter system at the Society for Information Display’s (SID) 2010 International Symposium, Seminar and Exhibition, being held at the Washington State Convention Center in Seattle, WA from May 23 through May 28, 2010.
This new UniversalPHOLED emitter system offers the potential for significantly reduced power consumption and extended operational lifetime in OLED devices.
The use of this new light-blue emitter system may provide performance benefits for both display and lighting applications. For lighting applications, it may accelerate the introduction of a variety of initial commercial products where high-efficacy, warm-white emission is important. The new system also offers key performance advances for displays when used in Universal Display’s new four sub-pixel format. Performance highlights for the new light-blue emitter system in these two applications will be detailed during symposium talks on Wednesday and Thursday of SID week.
“We continue to establish new records for what our high-efficiency, phosphorescent OLED technology and materials can deliver,” said Steven V. Abramson, President and Chief Executive Officer of Universal Display. “By introducing this new light-blue UniversalPHOLED emitter system to display and lighting manufacturers, Universal Display continues to lead the way in enabling superior OLED product performance.”
Universal Display’s new light-blue emitter system offers CIE coordinates of (0.17, 0.37) and a peak wavelength of 472 nm. It also provides a luminous efficiency of > 45 candelas per Ampere, corresponding to > 20% external quantum efficiency at 1,000 candelas per square meter (cd/m2). Under accelerated test conditions, this new emitter system demonstrates an operating lifetime of approximately 9,000 hours, to 50% of an initial luminance of 1,000 cd/m2. These performance gains are significant, representing a 30% increase in luminous efficiency and an almost 100% increase in operating lifetime, as compared to Universal Display’s earlier-generation light-blue PHOLED emitter system.
