Universay Display Corporation Awarded Department of Energy SBIR Phase I Contract for White OLED Lighting

Universal Display Corporation, an innovator behind today’s and tomorrow’s displays and lighting through its UniversalPHOLED phosphorescent OLED technology, today announced that it has been awarded a $99,919 Small Business Innovation Research (SBIR) Phase I grant from the U.S. Department of Energy (DOE) under the Department’s Solid State Lighting program.   
 
The program, titled “Enhanced Light Outcoupling in WOLEDs,” will focus on demonstrating a novel technique to improve the optical outcoupling efficiency of a white OLED.  Through the use of this novel technique, Universal Display intends to double the outcoupling efficiency, resulting in an external quantum efficiency of about 50%.
 
Using the Company’s high-efficiency UniversalPHOLED technology, white OLEDs can achieve up to a 100% internal quantum efficiency – meaning that all of the electrical energy can be converted into light.  Typically, only 20% of that light is directed through the front surface as useful light; however, an external component is often added to OLED panels to collect and emit more light.  By comparison, the novel approach proposed for this project involves integrating an outcoupling enhancement directly within the layers of the OLED device.  This approach has the potential to double the light output, while preserving the OLED’s thin form factor, and may also be significantly more cost effective to manufacture.  Such improvements are important for white OLEDs to achieve the DOE’s targets of 150 lumens per watt (lm/W) with a cost of less than $50/Kilolumen.  
 
“We are pleased to continue our work on energy-efficient white OLED lighting for the U.S. Department of Energy.  With their support, we have recently achieved a number of key technical milestones, including the demonstration of a research lighting panel with 102 lumens per watt,” said Steven V. Abramson, Universal Display’s Chief Executive Officer and President. “A tremendous opportunity exists for white OLED lighting products, based on their potential energy efficiency and environmental advantages as compared to existing lighting products.  Through programs such as this one, we look forward to demonstrating further progress toward the DOE’s commercial targets for solid-state white OLED lighting.”
 
Power-efficient white OLEDs may reduce energy consumption dramatically in a myriad of lighting applications.  They may also lower the amount of by-product heat generated by lighting devices, further reducing energy and environmental burdens.  White OLEDs are also
environmentally benign, when compared to mercury-containing fluorescent lamps and newer compact fluorescent lamps (CFLs).  Combining these important ‘green’ features with a very thin, lightweight and durable form factor, white OLEDs offer significant new lighting design opportunities.
