Research project for organic semiconductors

The UK's DTI is partly funding a research project to develop computational fluid dynamic (CFD) simulation techniques to model the drying behaviour of organic semiconductors.

Cambridge Display Technology, a pioneer in the development of polymer light-emitting-diode (P-OLED) technology, has been awarded another grant by the UK Department of Trade and Industry (DTI).

This grant will partly fund a project which will be important in the field of low-cost organic electronic devices, and especially in the development of low cost flexible displays.

The total value of project is around US $500k.

The project will aim to develop commercially viable computational fluid dynamic (CFD) simulation techniques to model the drying behaviour of organic semiconductors.

Until now, the production of working display prototypes has required the use of empirical data which is both expensive and slow to obtain.

Using the new models, the development cycle time should be significantly reduced.

Working with lead partner CDT on this project is Ansys, which has many years experience of multiphase free-flow modelling.

Ansys will implement the models for organic semiconductor drying behaviour in order to provide predictive tools within its Ansys CFX software, which should lead to further understanding of the complex drying process.

When completed, the materials process model will itself be made available commercially by the partners to display makers wishing to accelerate their own P-OLED display developments, as well as helping CDT to improve the performance and time to market of its own range of inkjet inks.

"The support of the DTI on this project is greatly appreciated", says Dr David Fyfe, CEO of CDT.

"It will allow us to make fast progress in improving our ability to develop inks and device technology, as well as potentially providing a new product in its own right".

"The announcement of this grant success comes after our announcement of work on metal deposition processes, also important in the development of flexible displays, and underscores the increasing importance which CDT puts on flexible display and OTFT development".
