摘要
We propose a bistable liquid crystal mode based on switching of the twist direction in a conventional pi/2-twisted nematic cell. Switching between the -pi/2 and +pi/2 twist states can be performed by applying vertical and/or in-plane electric fields. The proposed bistable mode has an infinite memory time because the two stable twist states have the same elastic free energy.
