AI Technical Summary

Technical Problem

Existing liquid crystal materials exhibit increased cleaning points under high-temperature conditions, leading to increased rotational viscosity and slower response speed, which fails to meet the needs of automotive and industrial displays.

Method used

By combining liquid crystal compounds of components I, II, III, IV, and V in specific proportions, the clearing point and rotational viscosity of liquid crystal materials can be adjusted. These compounds include CN-type compounds with high dielectric constant and high optical anisotropy, compounds with low viscosity and low melting point, compounds with high clearing point, and fluorine-based compounds with high dielectric constant, thereby optimizing the optical properties and viscosity of the liquid crystal composition.

Benefits of technology

This technology enables liquid crystal materials to exhibit high-definition bright spots and low rotational viscosity under high-temperature conditions, thereby expanding the operating temperature range and improving response speed.
