Universal Display Presents at Inaugural LED/OLED Lighting Technology Expo in Tokyo

Universal Display Corporation (NASDAQ:PANL), an innovator behind today’s and tomorrow’s displays and lighting through its UniversalPHOLED™ phosphorescent OLED technology, today announced that the company’s Chief Technical Officer Dr. Julie Brown presented at FINETECH JAPAN’s first ever LED/OLED Lighting Technology Exposition. The event was held in Tokyo, Japan from April 15 – 17.

Dr. Brown’s presentation, titled “Pushing the Envelope for White OLED Efficiency,” focused on white phosphorescent OLEDs (PHOLEDs) as an environmentally-friendly, energy-saving lighting technology. Dr. Brown reported data for a series of white PHOLEDs that span a range of white colors that were designed to satisfy the requirements of differing lighting applications. These research results range from warm to cool white with varied power efficacies of 54 to 102 lumens per watt (lm/W). Depending on the specific designs employed, the color rendering indices (CRI’s) varied from 70 to 88, and lifetimes varied from 4,000 to 17,000 hours (to 70% of initial luminance at 1,000 nits*).

Unlike incandescent and fluorescent lighting, white OLED performance characteristics can be tuned by manipulating the OLED materials and structures that are used. To show this effect, a series of white OLEDs, from approximately 2,700 to 4,000 Kelvin, were developed that exceed the Energy Star Category A Color Specification of color rendering index (CRI) of > 75 and the Efficiency Specification of > 35 lm/W. The Energy Star lifetime specification is ≥ 25,000 hours (to 70% of initial luminance at 1000 nits*), however, the lifetime results for this series may be sufficient for a variety of niche products while the Company continues to develop white OLEDs that meet the requirements for more demanding applications.

“The world is coming to the realization that solid-state OLED lighting can offer a meaningful eco-friendly and energy-saving lighting solution, and that our phosphorescent OLED technology is key to making this happen,” said Dr. Brown, Senior Vice President and Chief Technical Officer of Universal Display. “The recent advances we have made in efficiency, color and lifetime of our white PHOLEDs move us closer to meeting the U.S. Department of Energy’s solid-state lighting targets and the requirements of Energy Star, a joint specification between DOE and U.S. Environmental Protection Agency.”

FINETECH JAPAN’s LIGHTING JAPAN expo, sponsored by the Japan Luminaires Association and the Japan Electric Lamp Manufacturers Association, brings together innovators, manufacturers and designers in the LED/OLED lighting industries to showcase equipment, components and materials, as well as recent advances in LED/OLED lighting technologies. Presenters and exhibitors include companies from Japan, the United States, Germany, South Korea, Taiwan and China, among others. For more information, visit http://www.lightingjapan.jp/english/.

*Note: Based on the established conventions of the display industry, Universal Display typically reports OLED operating lifetimes as time to 50% of initial luminance. The lighting community is evolving to define lifetime targets based on time to 70% of initial luminance. Data in this release has been reported to conform to this target.

IoT & Smart Cities Stories
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
According to Forrester Research, every business will become either a digital predator or digital prey by 2020. To avoid demise, organizations must rapidly create new sources of value in their end-to-end customer experiences. True digital predators also must break down information and process silos and extend digital transformation initiatives to empower employees with the digital resources needed to win, serve, and retain customers.
