In the second such move within the space of one month, UK-based Cambridge Display Technology (CDT), a developer of Light Emitting Polymers (LEPs), has signed a license and technical assistance agreement with Sumitomo Chemical to advance the development of polymers for use in LEP technology.
CDT will license to Sumitomo some of its basic LEP materials IP, enabling Sumitomo to develop new conjugated polymers. Sumitomo will provide these new polymer samples to CDT for testing and evaluation in a variety of electronic display structures.
On the 15th of November, CDT reached a licensing agreement with the Dow Chemical Company. Dow announced the commercial availability of its green LEP in October 2000 and plans to launch red materials by year-end and blue materials in the next nine months.
The month before, CDT revealed that DuPont was also to receive a non-exclusive license to CDT technology to enable the company to produce both active and passive light emitting polymer display devices,
To date, CDT has also granted licenses to Delta Electronics, OSRAM, Philips, and Seiko-Epson. Additionally, CDT is collaborating with other companies in Asia.
