Liquid crystal composition containing a pentenyl compound, and applications thereof

Abstract

The present invention relates to a liquid crystal composition containing a pentenyl compound, wherein the liquid crystal composition contains at least one or a plurality of compounds represented by aformula I, one or a plurality of compounds represented by a formula II, and one or a plurality of compounds represented by a formula III, has a large elastic constant, easily achieves the afterimage recovery of liquid crystal display devices, and can improve the afterimage problem of liquid crystal display devices and improve the quality of liquid crystal display devices, such that the liquid crystal composition is suitable for fast-response TN, IPS and FFS type TFT liquid crystal display devices, and is particularly suitable for IPS and FFS liquid crystal display devices. The formulas I, II and III are defined in the specification.

Description

technical field [0001] The invention relates to liquid crystal materials and the application field thereof, in particular to a liquid crystal compound containing fluorinated terphenyl, in particular to a liquid crystal composition with fast response. Background technique [0002] At present, LCD product technology has matured, successfully solved technical problems such as viewing angle, resolution, color saturation and brightness, and its display performance has approached or exceeded that of CRT displays. Large-size and small and medium-sized LCDs have gradually occupied the mainstream position of flat panel displays in their respective fields. However, the afterimage problem of liquid crystal displays has always plagued the field of liquid crystal displays. The afterimage problem is mainly caused by the phenomenon that the previous picture is still retained after the liquid crystal display stays in a static picture for a long time. The main reason is that the ion accumula...

Problems solved by technology

However, the afterimage problem of liquid crystal displays has always plagued the field of liquid crystal displays. The afterimage problem is mainly caused by the phenomenon that the previous picture is still retained after the liquid crystal display stays in a static picture for a long time. The main reason is that the ion accumulation and recovery ability are poor.
