Abstract

The invention provides a liquid crystal complex and prepartion method thereof, the liquid crystal complex includes a liquid compound and a nano-particle, wherein the liquid crystal compound is an optical compensation bending type liquid crystal compound, and main chain or side chain of the nano-particle has at least an acrylic functional group. Content of nano-particle in formula of liquid crystalcomplex is 0.1 to 2 wt%, its weight percentage uses weight of liquid crystal complex as standard. When the nano-particle is added into original liquid crystal complex, liquid crystal can be convertedfrom divergence state to bending state quickly, such that liquid crystal device can reach a stable state quickly at initial driving, which is a drive loop without special high-voltage and with rapidresponse speed.

Description

technical field [0001] The present invention relates to a liquid crystal compound, in particular to a liquid crystal compound of optical compensation bending type. Background technique [0002] In recent years, related technologies of the flat panel display industry, such as liquid crystal displays (Liquid Crystal Display, LCD), have matured. At present, liquid crystal displays (LCDs) have been widely used in various electronic products, such as personal computers, notebook computers and other large-scale products using thin-film transistor displays (Thin-FilmTransistor LCDs, TFT-LCDs), or PDAs, language translators, etc. Computers, mobile phones and other small-sized products that use Super Twist Nematic (STN) technology can be seen using liquid crystal products. [0003] Although the liquid crystal display has the advantages of low radiation and small size, when the user views the liquid crystal display from different angles, as the viewing angle increases, the contrast r...
