- Abstract
We report a method for fast gray-to-gray (GTG) switching of a homogeneously aligned liquid crystal (LC) cell. Homogeneously aligned LCs are instantly vertically aligned by applying a vertical electric field for a short period of time before switching to a target gray level. Once the LCs are vertically aligned, we apply an in-plane voltage higher than the data voltage that corresponds to a target gray level, while maintaining the vertical electric field. Then, at the time the vertical field is removed, we apply a data voltage required for switching to the target gray level. We experimentally demonstrate GTG switching of a homogeneously aligned LC cell at a low temperature (-20°C), which is 7.5 times faster than a fringe-field switching (FFS) cell at the same temperature, which is comparable to the switching speed of a fringe-field switching cell at room temperature (23°C).
