摘要：

A new concept of a passive matrix ferroelectric liquid crystal display (FLCD) with a memorized gray scale is proposed. The physical origin of the gray scale in ferroelectric liquid crystal displays is considered. The criterion of reliable bistability is derived depending on the FLC hysteretic behavior in an electric field. The frequency and temperature dependences of the FLC hysteretic loop are discussed. A new approach for multiplex electronic addressing of the FLCD gray scale is given. A passively addressed 64 x 64 FLCD based on the photoalignment technique is developed. New applications of passively addressed FLCDs with a memorized gray scale are envisaged.
