Strongly strongly being the dielectric it possesses the dielectric seizure prevention

摘要

The ferroelectric liquid crystal device is a method of preventing and recovering the occurrence of seizure. A low frequency AC voltage is applied to the ferroelectric liquid crystal device to form a multi domain in the pixel, the domain boundary is made to flow, and the miniaturization of the domain region is induced. A voltage having a frequency of 10 to 100 Hz and an amplitude of + 1.5 to u00b1 3.0 V is applied to a low frequency AC voltage for a predetermined period of time, for example, 30 seconds or more. The AC voltage of the low frequency is applied to the liquid crystal device immediately before the driving of the liquid crystal is stopped or immediately after driving of the liquid crystal. Also, an AC voltage of a low frequency is applied when it is detected that a liquid crystal has occurred in the liquid crystal device.
