Problems solved by technology

When the positive liquid crystal is used in IPS / FFS display mode, it can obtain fast response and good reliability; while the negative liquid crystal can obtain higher transmittance when it is used in IPS / FFS display mode, but due to the negative liquid crystal The viscosity is relatively large, so the response speed is slow

Abstract

The invention relates to a liquid crystal composition, in particular to a liquid crystal composition of a polarity compound based on positive dielectric anisotropy. The liquid crystal composition comprises one or multiple of polarity compounds shown in a formula I, one or multiple of polarity compounds shown in a formula II, one or multiple of compounds shown in a formula III, and one or multipleof compounds shown in a formula IV, wherein the structures of the formula I, the formula II, the formula III and the formula IV are shown in the attached figures. The liquid crystal composition has the beneficial effects that the penetration rate is improved, and the obvious function on improving contrast ratio is realized; the liquid crystal composition is especially suitable for liquid crystal display elements and liquid crystal display devices of active matrixes IPS-TFT and FFS-TFT with low box thickness, high display quality image. (The formulas are shown in the description.).

Description

technical field [0001] The invention relates to a liquid crystal composition, and also relates to an application of the liquid crystal composition in the field of liquid crystal displays. Background technique [0002] Liquid crystals have now been widely used in computers, notebook computer displays, LCD TVs, and the like. The basic principle of using liquid crystal as a display material is: with the change of the electric field strength, the liquid crystal molecules will rotate regularly by 90 degrees, thus changing the light transmittance, and the liquid crystal will change from disordered transparent to ordered opaque, resulting in light and dark According to this principle, the light and shade of each pixel on the image can be controlled to form the desired image. [0003] The display methods of liquid crystals are not the same, and can be roughly divided into thin film transistor liquid crystal display (TFT-LCD), cholesteric nematic phase change liquid crystal display ...
