  摘要：

  本发明涉及一种具有如公式I所示结构的液晶化合物，其中R从H和烷基或含有1-12个碳原子的烷氧基中选择，其中一个或多个H未取代或用卤素取代；A1、A2和A3分别独立选择自：单键，1,4-环己烯基，1,4-苯基，其中1,4-苯基中的氢原子可以各自独立地被一个或多个卤素取代；Z1和Z2各自独立选择自单键或—(CH2)2—。该发明的化合物具有低转动黏度、大介电各向异性、良好的互溶性和稳定性的特点。在将该化合物添加到组合物后，设备的驱动电压可以显著降低。因此，该发明的化合物在液晶显示行业有着广泛的应用前景。

  The present invention provides a novel liquid crystal material composition comprising one or more compound, in order to achieve the properties of low viscosity, high resistivity, good low-temperature mutual solubility, fast response, excellent transmission, and which can be used for a variety of fast response display modes. Since the working temperature of a LCD material is subjected to the temperature range of individual LC molecules, information can only be displayed in a specific temperature range of the specific liquid crystal macro-alignment phase. At low temperature, the viscosity of liquid crystal increases exponentially, which in turn substantially reduces the response speed and overall performances of the display system. The liquid crystal composition according to the present invention overcomes these problems with balanced chemical composition by achieving low viscosity, good low-temperature performance and excellent transmission in a wide range of LCD applications including TN, IPS or FFS displays, thus improving display performance.

  本发明提供了一种由一种或多种化合物组成的新型液晶材料组合物，以实现低粘度、高电阻率、良好的低温互溶性、快速响应、优异的透射率等特性，可用于多种快速响应显示模式。由于液晶材料的工作温度受制于单个液晶分子的温度范围，因此只能在特定液晶宏配位相的特定温度范围内显示信息。在低温条件下，液晶的粘度会成倍增加，从而大大降低显示系统的响应速度和整体性能。本发明的液晶组合物通过平衡化学成分克服了这些问题，在包括 TN、IPS 或 FFS 显示器在内的广泛液晶应用中实现了低粘度、良好的低温性能和出色的传输性能，从而提高了显示性能。
