Universal Display and LG Display have renewed their commercial supply agreement - till the end of 2011. The companies are still negotiating a long-term agreement. UDC also extended their license with Samsung a few days ago.
The original agreement between UDC and LG Display (LG.Philips back then) was signed on May 2007. LG is using UDC's PHOLED materials in AMOLED displays, and pay them license fees.
