摘要： Sequentially performed are (1) an entire liquid crystal layer is initialized into a focal conic state, (2) an image is written onto the liquid crystal device by scanning with selecting exposure or non-exposure while applying a voltage that does not exceed a threshold value for a state change from the focal conic state to a homeotropic state during the non-exposure but exceeds the threshold value during the exposure and that causes the focal conic state and the homeotropic state to be bi-stable after the exposure, and (3) the application of the voltage is stopped to change a state of a portion, of which the state has changed to the homeotropic state, to the planer state. In (2), an electric field energy applied to an exposure portion of the liquid crystal layer is controlled to gradually increase from a start to an end of the series of scanning actions.

摘要： A driving method of a liquid crystal device for recording an image, the liquid crystal device including a liquid crystal layer having a cholesteric liquid crystal, a photoconductor layer accumulated on the liquid crystal layer, and electrodes, includes initializing an entire liquid crystal layer to a focal conic texture by applying a voltage exceeding a threshold value of transition from a planar texture to a focal conic texture, exposing the liquid crystal device imagewise while applying a voltage not exceeding a threshold value from the focal conic texture to a homeotropic texture upon non-exposure but exceeding the threshold value upon exposure and that provides bistability of the focal conic texture and the homeotropic texture with hysteresis upon non-exposure, and fixing a displayed image by releasing an application of voltage to change a part of the liquid crystal layer changed to the homeotropic texture to the planar texture.
