UDC, Mitsubishi Chem to work on inkjet-printable OLEDs

May 31, 2006 – Universal Display Corp. (UDC) and Mitsubishi Chemical Corp. have agreed to codevelop materials for phosphorescent organic light-emitting diode (OLED) displays that are processable through solution, or “wet” processing methods, such as inkjet printing.

The technology, which promises high efficiency of phosphorescent technology with lower-cost inkjet printing techniques, is projected for use with large-area OLEDs, seen as a strong growth market in coming years.

Universal Display has developed a proprietary “PHOLED” phosphorescent OLED technology, which it claims offers up to 4x higher efficiency than conventional OLED technology. Late last year, Mitsubishi Chemical and Mitsubishi Chemical Group’s Science and Technology Research Center unveiled a printable high-efficiency blue phosphorescent OLED. Together, the companies aim to accelerate development of printable red, green, and blue phosphorescent materials.

“Collaborating with a world-class chemical company like Mitsubishi Chemical allows us to share ideas and help each other reach the next level of innovation for OLED materials based on our PHOLED phosphorescent OLED technology and Mitsubishi Chemical’s expertise in OLED chemicals and ink formulation,” stated Steven Abramson, president and COO of Universal Display.
