This project takes a systems approach to develop and co-optimize four key technologies in parallel to bring about a significant advancement in the power efficiency and lifetime of OLED based white-light illumination devices. The four key technologies areas are: light extraction efficiency enhancement, low operating voltage materials and structures, high quantum efficiency and stable white emitters, and stacked-architecture.

The project leverages the extensive OLED materials and device expertise in Kodak Research Laboratories and Kodak Display Business Units. It combines extensive modeling and experimental work. It is expected that at the end of the two-year project we will deliver an OLED device architecture having over 50 lm/W power efficiency and 10,000 hours lifetime at 1000 cd/m2. The device will be suitable for development into successful commercial products.
