Summary on Grant Application Form
Mathematical models will be developed and exploited in order to describe recent experimental results which demonstrate fast, solitan switching in smectic liquid crystals. This research will begin by formulating the governing equations in a general two-dimensional setting incorporating flow by using a nonlinear smectic continuum theory. Analytical and numerical work will be undertaken on the properties of soliton switching coupled with flow and the stability of the related equilibrium configurations. The objective of this work is to discover the dominant controlling features of such switching, leading to ways of optimizing the characteristic switching times and isolating the most stable equilibrium configurations for the director profile within the cell.The proposed research is not only motivated by a general mathematical and scientific interest, but also by the considerable potential for exploitation of smectic liquid crystals in display devices. The subsequent results will lead to the development of devices which have significant advantages over currently and much used super twisted nematic and twisted nematic displays, such as a faster response suitable for video rate applications and improved viewing angles.It is expected that such an investigation will have a significant impact on the development of commercially viable novel advanced display technologies.
