A novel fast‐switching LCD with dual‐domain bend mode

Abstract A novel fast‐switching LCD with dual‐domain bend (DDB) mode is described. DDB alignment is achieved using antiparallel‐rubbed cell filled with chiral‐doped LC. Initial alignment is mono‐domain 180‐degree twist. Tilt direction is controlled by oblique electric field to be counter direction in each domain. Twist‐to‐DDB deformation occurs continuously so that DDB mode does not require high‐voltage initialization which is inevitable in Optically Compen sated Bend (OCB) mode. DDB gives wide and symmetric viewing angle in contrast to mono‐domain bend formed from 180‐degree twist showing strong asymmetry.
