Document Type and Number:
WIPO Patent Application WO/2021/127949
Kind Code:
A1
Abstract:
Disclosed are a liquid crystal composition adaptable to relatively wide operating temperatures and a preparation method therefor. The preparation method involves using a compound of general formula I, a compound of general formula II, a compound of general formula III, a compound of general formula IV, a compound of general formula V, a compound of general formula VI, a compound of general formula VII and a compound of general formula VIII as raw materials and compounding same in an appropriate ratio to finally prepare the liquid crystal composition. The liquid composition further contains polycyclic, alkynyl, cyano and ester compounds, has the properties of a high clearing point and a large optical anisotropy, and has a relatively wide operating temperature range and can adapt to high-temperature environment conditions. The liquid crystal composition can be applied to various display devices, especially PDLC devices.
