Liquid crystals have many applications in electro-optic devices and systems. We are studying a number of different systems that can use them. These include optical filters for telecommunications, gas sensors for environmental testing and pattern recognition systems using adapted liquid crystal TVs. We are also researching some of the aspects of liquid crystal displays (LCDs) themselves. This work concentrates on modelling the switching of liquid crystals, important in the design and improvement of very high resolution LCDs as well as the optical properties of the overall display. We have strong links with relevant industries for all of the projects.
