CAMBRIDGE, United Kingdom, 19th October 2005 - Cambridge Display Technology (CDT) [Nasdaq: OLED] and Sumitomo Chemical have announced the name of their proposed joint venture operation: the company will be called Sumation KK.  Sumation™ will develop and supply advanced polymer OLED (P-OLED) materials and formulated inks for use in commercial P-OLED display and lighting applications.

The intention to form Sumation was announced in May this year, and completion is expected around the end of October.

Sumation will be based in Tokyo, with R & D in Japan and the UK, and materials will be produced on behalf of Sumation by Sumitomo Chemical at their plant in Osaka, Japan, taking advantage of Sumitomo's extensive experience in fine chemicals manufacture.

Dr Susumu Miyazaki has been named as President of the company, which is staffed by personnel from both CDT and Sumitomo. Dr Scott Brown, formerly CDT's VP of R&D, has relocated to Japan as Executive Vice President to ensure a strong interaction between the UK and Japan-based R & D groups and co-ordination between CDT and Sumitomo.

Prior to the announcement of the jv, Sumitomo Chemical purchased the lumation™ business from The Dow Chemical Company, and Sumation has access to what is believed to be the largest portfolio of P-OLED material development expertise and intellectual property (IP) in the industry.  This includes both the current best-performing full colour P-OLED materials based on polyfluorene chemistry, and high-efficiency materials based on dendrimer chemistry, the technology which CDT gained through the acquisition of Opsys in 2002.

Sumation will combine the high quality chemicals manufacturing experience of Sumitomo with the leading edge P-OLED development know-how of CDT and Sumitomo. Through Sumation, display and lighting companies will have access to the very best performing materials. The synergies which flow from combining the experiences of the companies should increase the pace of development of P-OLED materials, and in turn this is expected to accelerate the adoption of the technology in the next generation of consumer products such as mobile phones, portable DVD players and ultimately televisions.

About CDT
Cambridge Display Technology is a pioneer in the development of light emitting polymers (P-OLEDs) and their use in a wide range of electronic display products used for information management, communications and entertainment. P-OLEDs are part of the family of organic light emitting diodes, or OLEDs, which are thin, lightweight and power efficient devices that emit light when an electric current flows. P-OLEDs offer an enhanced visual experience and superior performance characteristics compared with other flat panel display technologies such as liquid crystal displays, and have the key advantage that they can be applied in solution using printing processes. Founded in 1992, the company is headquartered in Cambridge, UK and listed on the US Nasdaq stock exchange under the symbol 'OLED'.
