MAY 2--Bayer AG (Leverkusen, Germany), which serves the global health-care, agriculture, polymers, and chemicals industries, and Cambridge Display Technology (CDT; Cambridge, UK;www.cdtltd.co.uk), commercial developer and owner of the fundamental intellectual property for light-emitting polymer (LEP) technology, have signed a support agreement for the commercialization of critical materials used in the manufacture of LEP displays. Under terms of the agreement, Bayer AG will manufacture, sell, and market Baytron products to LEP display developers and manufacturers, and CDT will provide technical support for their use.
The agreement covers key intellectual property jointly owned by Bayer AG and CDT for a high-resistance version of polyethylene dioxythiophene polystyrene sulphonate (PEDOT/PSS), the critical charge-transport material used in LEP display devices that has reduced crosstalk, which is vital for higher-resolution and high-pixel-count displays. This agreement is the direct result of the successful codevelopment of these materials by the two companies, which took place under a joint-development agreement in 2001.
