Summary on Grant Application Form
Photoluminescent liquid crystal displays (PL-LCDs) have a novel architecture using liquid crystal shutters to control narrow band excitation onto phosphors which emit light to the viewer. The aim of the project is to develop liquid crystal mixtures suitable for use in bright PL-LCDs that require illumination near 365nm. Such mixtures must be specially designed for long-term transparency and stability at this wavelength as well as low switching voltages, low melting point, high nematic clearing point and low viscosity. Appropriate elastic and dielectric constants are required to allow suitable threshold voltages for high-duty multiplexing and/or greyscale performance depending on the application. The birefringence must be large as possible, consistent with photochemical stability, in order that the cell thickness can be minimised.
