METHOD FOR RESTORING DISORDERED LIQUID CRYSTAL ORIENTATION AND APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To restore disordered orientation of an antiferroelectric liq. crystal due to thermal shock to improve contrast in a short time by a simple method or apparatus. ;SOLUTION: In an antiferroelectric liq. crystal cell 10 comprising two electrode plates 2 and 3 and an antiferroelectric liq. crystal compsn. 1 held between the electrode plates 2 and 3, the orientation of the liq. crystal compsn. 1 is disordered by thermal shock. The disordered orientation is restored by applying a d.c. voltage of 10-100V, optimally 40V, to between the electrode plates 2 and 3 for from few sec to few min, optimally 5sec.;COPYRIGHT: (C)1997,JPO
