The characteristics of SSFLC cells with stripe-shaped domain structure

The stripe-shaped domain (SSD) structure has been obtained in the initial f erroelectric liquid crystal (FLC) alignment by doping phthalocyanine compou nd into the rubbed polyimide films. Atomic force microscopy (AFM) was used to investigate the aligning films and the corresponding aligning ability wa s evaluated through the pre-tilt angle measurement. The memory capability a nd the contrast ratio of the aligned SSFLC cells have been enhanced and imp roved with the appearance of the SSD structure. In addition, the stability of 64 x 80 electrically controlled FLC spatial light modulator has been imp roved, too. The possible formation mechanism of the SSD structure was also discussed.
