SAN DIEGO, Nov. 15 -- The Dow Chemical Co. and Cambridge Display Technology (CDT) have reached an agreement licensing CDT's polyfluorene light-emitting polymer (LEP) technology to Dow. Dow and CDT had been working separately to develop polymers for use in LEP displays, which are organic light-emitting displays (OLEDs). The agreement, which is only for material intellectual property (IP), provides Dow access to CDT's IP to polyfluorene-based LEPs and establishes guidelines for future development between the companies. As Dow improves its current LEP materials and develops new products, CDT will test the materials in both its Cambridge labs and its pilot technology development facility being constructed in nearby Godmanchester, UK. OLEDs are expected to be deployed in instrument panels and portable electronics such as mobile phones and personal digital assistants, and eventually larger displays for personal computers and consumer products, where they could overtake liquid-crystal display technology in the future.
