Abstract:
Provided is a set of techniques for measuring different properties or parameters of liquid crystal mixtures by applying a driving waveform and measuring the response current and/or the optical response. This may be done by using specific liquid crystal test cells. Also provided are the optimized test cell parameters that are used in the algorithms for calculating the properties.
