Fast response liquid crystal mode

A novel fast nematic liquid crystal mode is proposed. It relies on the fast relaxation flow from bend state to the twisted state in the optically compensated bend mode. Such new liquid crystal mode is indeed an improved mode from the optically compensated bend mode as it does not require any holding voltage. The new liquid crystal mode has fast response time and high contrast. The proposed fast liquid crystal mode is a good candidate for applications, such as optical shutter, field sequential color display, and 3D display.
