Merck are working toward solution-processable OLED materials, and are now saying that they expect to have a green material that is comparable to vacuum processable green within 9 months. Merck's materials will be suited for large-area panels such as OLED TV panels.  

Merck's OLED material development started in 2005 when they bought Covion. They say that the NEMO project (started in 2009) was a real boost to the performance of their materials.
