February, 24, 2005, Cambridge, United Kingdom--Cambridge Display Technology (CDT) and Toppan Printing (Tokyo, Japan) have announced the commencement of Phase Two of their joint program to explore alternative printing processes for the fabrication of displays based on light emitting polymer (PLED) technology.

Phase One, completed at the end of 2004, concentrated on proving the feasibility of using a roll printing process to deposit light emitting polymer materials onto a glass substrate. This technique would enable device manufacture based on roll-to-roll processing with attendant low costs of production.

Phase Two focuses on the performance of roll printed displays. It aims to produce displays by roll printing which have lifetime, efficiency and color fidelity comparable to displays produced by ink jet printing. Full color demonstrators of VGA resolution and 12" diagonal will be the product of the next two year program.

Both CDT and Toppan are very pleased with the results of Phase One and are optimistic about the prospects for future success. The first objective of the developments has been accomplished, and the feasibility of roll printing for this application was indicated successfully.

David Fyfe, CEO of CDT, said "The combination of Toppan's skills in conventional printing processes and those of CDT in light emitting polymer ink formulation and device structure, enhance the chances for success in this promising project to create very low cost displays".
