TOKYO & CAMBRIDGE, United Kingdom--(BUSINESS WIRE)--June 14, 2002--

New Venture Company, Polyink, Will Offer Total Solutions Package That
Includes Providing Ink Jet Printing Machines and Inks for LEP Displays

Seiko Epson Corp., Japan, and Cambridge Display Technology Ltd. (CDT),
U.K., have reached an agreement after several years of joint development to
form a joint venture company to offer technologies and services using
ink-jet deposition for manufacturing Light Emitting Polymer (LEP) displays.
LEPs, which are easily soluble in solvents, can be laid down in arrays
forming Red, Green, Blue (RGB) pixels by ink jet printing. The drop sizes
used to create pixels are extremely low volume, which has necessitated
major development of printer head technology and ink jet formulations to
match these heads.
This ink jet printing method provides a high efficiency in utilization of
the polymer materials, yields efficient devices and holds the promise of
low-cost manufacturing of LEP displays.
Seiko Epson and CDT have worked jointly on these issues for several years,
utilizing Seiko Epson's ink jet printing technologies and CDT's ink
formulation technologies, and have reached the stage at which
commercialization can take place.
The two companies are moving into this commercialization to provide an ink
jet printing machine with Epson's print head and inks whose formulations
have been specified by CDT especially for these heads.
Seiko Epson and others have already demonstrated ink jet printing as a
route to high-resolution full color LEP displays. The new company, named
"Polyink," will be jointly established to offer a "total solution package"
to, in particular, display makers making high resolution, active matrix
"Seiko Epson is clearly a world leader in the development and
commercialization of ink jet technology," said David Fyfe, CEO of CDT. "Our
companies have been collaborating in this field for a number of years to
apply its potential for lower cost, higher throughput manufacturing of LEP
"The Polyink venture is the natural culmination of this substantial
investment by our companies. We have put together a venture whose strategy
fits well both with Seiko Epson's business model, as well as with CDT's
plan to provide open commercial solutions and critical technologies to our
