The standard approach to increasing the speed, contrast and brightness of conventional TN and STN liquid crystal displays has, up to now, involved the development of nematic liquid crystal mixtures possessing elastic and dielectric material properties that have been specifically tailored for the particular type of display.This process has relied on the ability to accurately measure these material properties, to understand the relationships between these properties and the structures of the components of the nematic mixtures, and to be able to use the values of the material properties obtained in mathematical simulations that accurately predict the electro-optical properties of the display.In this proposal an additional material property, the flexoelectric polarisation, which occurs when a nematic liquid crystal director field is distorted, will be taken account of for the first time in a mixture development process that is targetted towards both conventional TN and STN displays, as well as promising bistable nematic, pi-cell and cholesteric display modes. This process will be informed by an underpinning investigation of the relationship between the magnitude of the flexoelectric polarisation and the different molecular ordering effects that can occur in nematic materials.
