The invention discloses a double-frequency bi-stable
liquid crystal display and double-frequency bi-stable
liquid crystal composition. The double-frequency bi-stable
liquid crystal composition made by mixing double-frequency liquid
crystal, chiral composition and nematic phase liquid
crystal composition is poured into a liquid
crystal box; through the component ratio and chemical features of the double-frequency bi-stable liquid crystal composition, the liquid crystal composition mixed has the features of both the double-frequency liquid crystal and the cholesteric phase liquid crystal, under driving of a
frequency modulation mode, two optical statuses, namely focal conic texture and planar texture, can be converted through
dielectric anisotropy of the liquid crystal, and an image can be displayed; thus, the double-frequency bi-stable
liquid crystal display can be in the two optical statuses without
voltage maintaining or decomposing the
helix structure of the cholesteric phase liquid crystal through
high voltage;
dielectric conversion is not related to metastable state conversion,
power consumption of the double-frequency bi-stable
liquid crystal display is effectively reduced, and conversion time is effectively shortened.
