Princeton University, a research partner of Universal Display Corp. (UDC), has received a patent for an organic vapor phase deposition (OVPD) process that can provide substantial advantages in the manufacture of OLED FPDs.

According to UDC, it has the exclusive, global rights to U.S. patent no. 6,337,102, titled "Low Pressure Vapor Phase Deposition of Organic Thin Films." The company claims the patented process could produce thin films that have superior surface properties compared to traditional OLED processing.

The advantages of OVPD technology include higher materials utilization, increased control over the deposition process, higher potential throughput, yield and lower manufacturing costs. UDC says OVPD technology also provides a significant step toward Web-based continuous process fabrication for organic electronics, including OLEDs, being uniformly and efficiently deposited on thin and flexible surfaces.
