The principles for intrinsic greyscale generation and stabilization of bistable photoaligned FLCD are discussed and investigated. In order to realize these principles, the passive matrix driving scheme for FLCD is proposed and studied. Passive 160×160 matrix addressing photoaligned 5μm reflective FLC display (48mm×46mm) with high contrast and 4 memorized grey scale levels is demonstrated. Images can be saved for very long time without any power supply. 15V driving voltage is only needed to refresh information, which is impressive and desirable for low power consumption display such as PDA, e‐paper etc.
