Cambridge Display Technology (CDT) has been awarded a grant by the UK Department of Trade and Industry (DTI) to allow it to develop commercially viable computational fluid dynamic (CFD) simulation techniques to model the drying behaviour of organic semiconductors. The total value of the project is around $500,000.
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 Europe, a subsidiary of ANSYS, which has many years experience of multiphase free-flow modelling. ANSYS Europe 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.
