Bayer is material to CDT's display developments

Bayer and Cambridge Display Technology (CDT) have signed a commercial support agreement for the commercialisation of critical materials used in the manufacture of LEP displays.

Bayer and Cambridge Display Technology (CDT) have signed a commercial support agreement for the commercialisation of critical materials used in the manufacture of LEP displays.

Under the terms of the agreement, Bayer 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 jointly owned intellectual property by Bayer and CDT for a high resistance version of polyethylene dioxythiophene polystyrene sulphonate (PEDOT/PSS), the critical charge transport material (hole transport layer, HTL) 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.

"We are pleased to put in place a commercial framework for the exploitation of these materials with Bayer", said David Fyfe, CEO of CDT.

"This builds upon the very close technical relationship between our companies, which has harnessed Bayer's highly processable conductive polymer materials expertise with CDT's LEP technology to produce this excellent product".

"Two years ago HC Starck entered into a joint development with CDT to tailor its materials for LEP applications", said Dr Aloys Eiling, Marketing Manager at HC Starck, a wholly owned subsidiary of Bayer.

"We see the co-operation with CDT as a major success factor in the development of the current material products as well as paving the way for future improvements of our product range".
