摘要 链烯基类液晶单体被广泛用于各种液晶显示器中。将常用的6款链烯基类液晶单体分别添加到基础配方P0中,配制了6款混合液晶,对其品质因子的相关性能进行了考察。结果表明,按相同比例添加的VCCPMe系列单体可以增高配方的折射率各向异性;HHV系列单体可有效降低配方的旋转黏度和优化品质因子,其中添加3HHV1的混晶具有最好的品质因子。 Liquid crystals with olefinic chain are extensively used for various kinds of LCD. Six kinds of liquid crystal mixtures were obtained by adding six olefinic liquid crystals to host mixture P0 respectively. The associated properties of Figure-of-Merit(FOM) were investigated. The results show that the series of VCCPMe is the most effective for increasing birefringence of the composition, for lowering rotation viscosity and optimizing FoM, the series of HHV is the best, and the 3HHV1 is the most benefit to FoM.
