Universal Display have entered into a three-year strategic alliance with Plextronics to develop and commercialize soluble OLED material systems. The new OLED systems will use combine Plextronics' HIL and HTL materials with UDC's PHOLED emissive materials. UDC also made a $4 million investment in Plextronics.
UDC and Plextronics were already collaborating before. Back in November 2010 Plextronics said that UDC's P2OLED system uses their HIL materials and OC NQ Ink.
Plextronics was founded in 2002 as a spin-out from Carnegie Mellon University. The company had between $5 million and $10 million in revenue selling ink to manufacturers and researchers in 2010 and 2011. In March 2011 we posted an interview with Plextronic's CEO, Andy Hannah.
