Universal Display (UDC) logoIn June, Universal Display announced a major breakthrough in white OLED power efficacy, 102 lm/W, in an all-phosphorescent OLED device. UDC reported that this device also provides an operating lifetime of 8,000 hours to 50% of initial luminance (at 1000 nits and without enhanced optical outcoupling), an operating voltage of 3.5 volts, a pleasing white color with a color rendering index (CRI) of 70, and a color temperature of 3,900 Kelvin.

“The discovery and development of UniversalPHOLED phosphorescent OLED technology was a major breakthrough that has enabled the potential use of white OLEDs for solid-state lighting,” said Steven V. Abramson, President and Chief Executive Officer of Universal Display. “Using this technology, power-efficient, bright and thin white OLEDs reduce energy consumption, while  remaining environmentally benign, especially compared to mercury-containing fluorescent lamps. White OLEDs also offer exciting new product design opportunities and an abundance of new  product applications. Our continuing advances in phosphorescent and white OLED technologies are now significantly accelerating solid-state OLED lighting towards commercial reality.”
