When I was a graduate student at UCLA in 1998, I heard of Professor their that already patented the process for using ink-jet printing techology for creating Organic LED devices.
The original paper is:
S.C. Chang, J. Bharathan, and Y. Yang; "Dual-color polymer LEDs processed by hybrid inkjet printing technology", Appl. Phys. Lett., 73, 2561, (1998).
