Abstract
A dynamic driving method of tri-stable cholesteric liquid crystals is described, and used to switch a planar arrangement stable state, a focal-conic arrangement stable state, and an uniform lying helix arrangement stable state of a cholesteric liquid crystal material by a two-stage selecting step. A switching time among the three stable states driven by a passive matrix method is effectively reduced.
