摘要: We report the results obtained from the studies of polymer-stabilized cholesteric texture films. Two sets of samples were
fabricated. The first set were fabricated by adding various ferroelectric liquid crystal (SmC*) dopant concentrations in the
mixtures. The second were fabricated using a dual-frequency liquid crystal. The experimental results obtained from the first
set show that adding a small amount of SmC* could significantly improve the cells' electro-optical (E-O) characteristics.
Both the driving threshold voltage and the rise time were decreased, while the hysteresis width was increased. The result
from the second set shows there exists a pronounced hysteresis effect in the transmission versus frequency curve at a given
applied voltage. The hysteresis width is increasing as the applied voltage is increasing. A display mode is proposed based on
this bistable feature.
