Sub-Millisecond Switching of Hybrid-Aligned Nematic Liquid Crystals

In this paper, we propose a method for sub- millisecond switching of hybrid-aligned nematic liquid crystals (LCs). The LCs are switched to the bright state through downward tilting and twist deformation initiated by applying an in-plane electric field, whereas they are switched back to the initial dark state through optically hidden relaxation initiated by applying a vertical electric field for a short duration. Using the proposed device, we experimentally obtained a total response time of 0.75 ms .
