Liquid Crystal Composition Suppressing Dropping Marks

The patent changes the molecular structure parameters by introducing specific substituent groups (fluoro, cyano, alkoxy) at defined positions on the bicyclohexane skeleton, and optimizes alkyl chain lengths to achieve the desired balance between response time and vapor pressure characteristics

The patent creates a composite liquid crystal composition by combining multiple compounds with different molecular structures (cyclic compounds, esters, alkyl benzoates) in specific ratios, where each component contributes different properties to achieve overall optimization of response time, vapor pressure, and temperature stability

The patent optimizes the chemical structure parameters of the liquid crystal compounds by selecting specific molecular weights, functional groups, and chain lengths that provide appropriate volatility characteristics to prevent dropping marks while maintaining fast response performance

The patent introduces specific functional groups (fluoro, cyano, alkoxy) at defined positions on the molecular structure to locally modify properties such as vapor pressure and dielectric anisotropy, achieving optimal balance between response speed and manufacturing quality

The patent optimizes the chain length and branching of alkyl side chains on the bicyclohexane skeleton to achieve the desired balance between transition temperature and response time, using specific carbon chain lengths (C3-C8) that provide appropriate thermal stability without excessive viscosity

The patent introduces specific substituent groups (fluoro, cyano, alkoxy) at defined positions on the cyclic skeleton to locally modify molecular interactions and polarity, achieving optimal balance between Tni and γ1 without requiring long alkyl chains that would increase viscosity
