Liquid Crystal Composition for Fast Response and High Voltage Holding

The patent modifies the molecular structure parameters of liquid crystal compounds by introducing specific substituents (fluorine atoms at positions 3 and 5, cyano groups at positions 1 and 4 on phenyl rings) to achieve optimal rotational viscosity and response speed characteristics

The patent creates a composite liquid crystal composition by combining multiple liquid crystal compounds with different molecular structures (cyclic compounds, linear compounds, and their derivatives) to achieve synergistic effects that simultaneously improve response speed and maintain stability

The patent introduces polar groups (cyano, fluorine) at specific local positions (positions 1, 4 and 3, 5 on phenyl rings) rather than uniformly throughout the molecule, creating localized polarity that enhances voltage holding ratio while minimizing overall viscosity increase

The patent optimizes the balance between polar group concentration and molecular size by selecting specific substituents and their positions, achieving the right parameter combination for both high voltage holding ratio and low viscosity

The patent combines liquid crystal compounds with different phase transition characteristics in a composite formulation, where the mixture maintains a higher overall phase transition temperature than individual components while preserving low viscosity and fast response properties

The patent adjusts molecular weight, chain length, and substituent types to optimize the phase transition temperature parameter while maintaining the low rotational viscosity needed for fast response, finding the optimal parameter range for both requirements
