Abstract
In order to evaluate the switching properties of FLC mixtures in their relation to addressing waveforms, alignment layers and general cell construction we have built an experimental setup which allows for dynamic measurements of the optical response of a test cell under real addressing conditions. In synchronisation with a selection voltage different data pulses can be sequentially applied and the corresponding optical response of a test cell can be recorded under computer control. Thank to this equipment we are able to record hysteresis curves of the response. On this basis we introduce some useful parameters (switching amplitude, image sticking) which can be measured and compared for different cells. The setup can provide several selection and data waveforms so that influence of their choice can also be studied.
