Electro-optic Behaviour of a Nematic Liquid Crystal Mixture


The optical properties of nematic liquid crystal mixture along with their electrical capacitance and dissipation constant were measured as a function of applied bias voltage and frequency. A bias field dependence of dielectric permittivity of the sample has been evaluated for various frequencies. Contrast ratio has also been evaluated and plotted against frequency and bias voltage. These parameters are crucial for understanding and optimising the performance of modal liquid crystal device.
