Stereo display is the developing trend of television industry

and Liquid Crystal(LC) lens is a key technology of autostereoscopy display. The LC mixture was used in LC lens required high birefringence and low rotational viscosity. A series of new monomer with dialkyne structure were developed

then its phase transition temperature and birefringence data were measured. After the compounds were substituted by fluorine

lower melting point and wilder nematic phase range were observed. When the new singles were applied to LC mixture

its excellent performance could meet the requirements of LC lens. However the poor ultraviolet resistance ability of dialkyne structure need be solved

which could be improved by adding anti-UV additive and better single purification technology at present.
