Superfast Low-Temperature Switching of Nematic Liquid Crystals Using Quasi-Impulsive Driving and Overdrive

In this paper, we report on the low-temperature, high-transmittance operation of a nematic liquid crystal (LC) cell. We investigated the electro-optic characteristics of a homogeneously-aligned LC cell over a wide temperature range. By applying high vertical and in-plane trigger pulse voltages between frames to an LC cell, the response time of the LC cell at -20 °C was decreased by 12.5 times compared to that of a conventional fringe-field switching (FFS) cell. In addition to providing a fast response, the LC cell exhibited the same high transmittance as an FFS cell over a wide temperature range.
