Abstract
We have proposed a vertically aligned fast response liquid crystal display (LCD) with three-electrode driving (FIS-VA-3T LCD). Both fringe and in-plane electric fields are used to obtain a strong horizontal electric field causing a high transmittance of the bright state. The normalised transmittance of the FIS-VA-3T cell is 12% higher than that of the previous vertically aligned liquid crystal cell with three-electrode driving (VA-3T). During the turn-off process, a trigger pulse is applied on the top electrode to compel the LC molecules vertically aligned rapidly to show the dark state. The turn-off is very fast (∼0.25 ms); 10 times as fast as that given by the vertical alignment liquid crystal cell (FIS-VA) driven by fringe and in-plane electric fields (∼2.5 ms). Such a fast response and high transmittance device is promising for colour sequential displays and other applications.
