LONDON Polymer light emitting diode developer, Cambridge Display Technology (CDT), has begun collaborative work on a metal deposition project which is expected to be important in the field of flexible displays.
This is one of a number of flexible display projects which CDT is working and says it will release details of the others in the near future.
The project is part-funded by the U.K. Department of Trade and Industry (DTI) and involves the development of a process to deposit high conductivity, very thin metal tracks onto glass and plastic substrates. The process, which is seen as an alternative to conventional inkjet printing methods, involves the use of lasers to expose selected material, and is capable of resolutions of less than 5microns.
Flexible displays are expected to require a technology such as this for the formation of the TFT backplane, and the process under development could be applicable to plasma (PDP) and LCD displays and even organic photovoltaics as well as P-OLEDs.
CDT partners in the project are Conductive Inkjet Technology (London), a subsidiary of Carclo plc, a specialist in technical plastic products, and Exitech (Oxford, England), supplier of laser processing equipment.
CDT expects to be able to report the outcome of this work by mid 2007.
