Abstract

The invention provides a liquid crystal mixture and application thereof. The liquid crystal mixture comprises at least one liquid crystal compound with a general formula I, wherein the general formula I is shown in the description; Y1 is any one of H or alkyls of C1 to C7; X1 and X2 are separately selected from H, F or CH3; Y2 is F, Cl, CH3, OCH3, -CH=CH2, CF3, OCF3 or OCHF2; two components are separately selected from any one of a group consisting of the following compounds (shown in the description); the liquid crystal mixture further comprises at least one liquid crystal compound with a general formula II, wherein the general formula II is shown in the description. The liquid crystal compound has a nematic phase with wider temperature range, higher elastic coefficient K, a higher dielectric anisotropic value and improvement on optical anisotropy and viscosity of the liquid crystal compound, thereby improving contrast ratio and light transmittance of a liquid crystal display, improving the quality of a display image and the response speed and benefiting energy conservation.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a liquid crystal mixture and its application. Background technique [0002] Since entering the video era, liquid crystal displays have become ubiquitous from smartphones, tablet computers to smart TVs, and liquid crystal displays have become an indispensable "milk and bread" for the information society. The rapid development of liquid crystal display has replaced the traditional cathode ray tube display and has become the mainstream product in the field of information display, which directly affects the rapid development of liquid crystal materials, an important part of it. [0003] Liquid crystal media are partially ordered, anisotropic liquids that lie between three-dimensionally ordered solids and isotropic liquids. G.Friedel and F.Grand-jean of France made detailed research on the structure and optical properties of liquid crystals, and completed the work of liquid cr...
