Description
technical field [0001] The invention belongs to the technical field of liquid crystal materials and liquid crystal display devices, and relates to a liquid crystal composition, in particular to a wide temperature liquid crystal composition, in particular to a wide temperature liquid crystal composition, a wide temperature polymer dispersed liquid crystal composition and a wide temperature liquid crystal composition. Polymer dispersed liquid crystal film. Background technique [0002] Polymer Dispersed Liquid Crystal (PDLC) is a new type of composite liquid crystal material with photoelectric properties. The research on this liquid crystal material began with the accidental discovery decades ago. It is composed of liquid crystal and polymer. The two-phase system uses UV or heating methods to disperse small molecule liquid crystals in a transparent polymer system to form micron-sized or nanometer-sized liquid crystal droplets. The polymer system provides a stable network struc...
