Materials Degradation Analysis and Development to Enable Ultra Low Cost, Web-Processed White P-OLED for SSL

In previous research, a specialty solid-state lighting (SSL) device had been developed. A doped Polymer Light-Emitting Diode (POLED) device structure is used, which enables devices to be printed with low capital equipment and operating costs. Although the devices are efficient, thin, flexible, and robust, additional performance improvements would broaden the range of applications to interior building, safety, and night lighting. This project will identify the primary efficiency degradation mechanisms for doped POLED devices (in Phase I), and then develop a next-generation materials set for high-efficiency, longer-lifetime printed devices. Phase II will involve product demonstration, process scale-up, and pilot manufacture. Commercial Applications and other Benefits as described by the awardee: The next generation POLED technology for SSL should improve energy savings and overall product performance in future building applications, including digital electronic signage, architectural lighting, safety lighting, emergency and portable lighting, and other specialty lighting products. The print-based manufacturing approach of this OLED technology has inherently low cost capital equipment and operating costs, which should facilitate the early adoption, product start-up, and large scale manufacture of SSL devices.
