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.

Abstract

The invention relates to a liquid crystal material and application fields thereof, particularly to a trifluoromethoxy-containing liquid crystal composition and applications thereof, wherein the liquidcrystal composition comprises compounds represented by general formulas I, II and III. According to the present invention, the liquid crystal composition has large elastic constant, easily achieves the afterimage recovery of liquid crystal display devices, can improve the afterimage problem of liquid crystal display devices and improve the quality of liquid crystal display devices, can particularly improve the display effects in TN, IPS or FFS mode display devices, and is especially suitable for IPS and FFS mode liquid crystal display devices. The formulas I, II and III are defined in the specification.

Description

technical field [0001] The invention relates to the field of liquid crystal material and its application, in particular to a liquid crystal composition containing trifluoromethoxy and its application. 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 accumulation and recovery ability are poor. . [0003] S...
