O'Regan discusses the approach to solution processing used at DuPont OLEDs that delivers printed devices with excellent electrical performance. A plenary talk from SPIE Optics + Photonics 2012.

Solution coating offers the potential for significant cost-savings in AMOLED production through efficient material utilization and the use of large size glass substrates. The DuPont approach to solution processing is based on small molecule OLED materials because of their superior performance. By tailoring the materials to tolerate solution coating in ambient clean-room conditions, DuPont is able to deliver printed devices with excellent electrical performance. Blanket layers are first deposited sequentially via slot die coating. The RGB sub-pixels are patterned by printing with a nozzle printer, where the pixels are filled by continuously extruding solution from nozzles moving at high speeds.

Marie O'Regan is the Technology Director at DuPont OLEDs in Santa Barbara, CA, where she is responsible for research and development activities in solution OLEDs. Prior to working at DuPont Displays, she was a research scientist at Eastman Kodak in Rochester, NY. Marie holds a B.Sc. degree in Chemistry from University College, Dublin and a Ph.D. in Inorganic Chemistry from MIT.
