Dual‐mode liquid crystal devices with switchable memory and dynamic modes

Abstract

A liquid crystal device with switchable dynamic and memory modes was investigated and developed. The proposed device reveals the splay, π‐twist, and bend states via selective switching among them. In the dynamic mode, the device is operated in the bend state, which exhibits a wide viewing‐angle and a fast‐response‐time due to its self‐compensated bend structure and flow‐accelerated fast response time, respectively. In the memory mode, the permanent memory characteristics in the splay and π‐twist sates are obtained, respectively. The switching mechanisms of the tristate device are also proposed.
