Paper Abstract

We introduce drive schemes for fast switching of nematic liquid crystals (LCs) using three-terminal electrodes. Fast switching of LCs can be achieved by employing a vertical trigger pulse, by applying a vertical bias field, and by employing quasi-impulsive driving and overdrive. 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.
