August 7, 2006 – Air Products has signed a deal to license, develop, and market products based on technology from the U. of Connecticut that aims to help increase the lifetime of polymer light-emitting diodes (P-OLED) for displays.
Focused on poly (thieno [3,4-b] thiophene), and dopant polymer technology from Air Products, the two groups have developed hole injection layer (HIL) materials for P-OLEDs that they claim provide a dramatic increase in display lifetime compared to conventional HIL materials. Air Products says P-OLEDs based on its HIL materials exhibit lifetime to half luminance up to 10x longer than conventional HIL materials based on competing thiophene polymers.
The two-layer architecture, which typically obviates the need for a costly protective interlayer, would help reduce process steps during display manufacturing, leading to higher device yields and reducing the need to purchase additional deposition tools.
“We believe that these patented materials will help to enable more rapid growth of the emerging OLED display industry,” stated John Dickenson, senior business development manager for Air Products.
