Abstract

The electro-optic properties of a vertically aligned liquid crystal device with a three-electrode structure for fast response applications have been studied. The fast response is realized by a three-electrode structure that can produce an electric field horizontally and vertically, alternately to turn the liquid crystal cell on and off so that both the turn-on and turn-off processes are driven by the electric field. The response time, transmittance–voltage curve, and the bias effect were characterized for cells with various stripe widths/gaps. A simple theoretical model was used to explain the bias voltage dependence of the transmission with good agreement with the experimental findings. A total response time (rise-time plus fall-time) of 1.88 ms was obtained.
