Abstract:
A method of image sticking prevention and recovery treatment for a ferroelectric liquid crystal device having a ferroelectric liquid crystal layer and electrodes to which a first voltage is applied for driving the liquid crystal device, wherein a low-frequency AC voltage, distinct from the first driving voltage used to drive the liquid crystal device, is applied to the electrodes for forming multiple domains in which bright display regions and dark display regions are intermingled in a pixel in said ferroelectric liquid device, causing domain boundaries to flow, and inducing fine segmentation of domain regions, said low-frequency AC voltage having a frequency of 10 to 100 Hz and an amplitude of Â±1.5 to Â±3.0 V and applied to said ferroelectric liquid crystal device for a predetermined period.
