A liquid crystal composition

Abstract

The invention discloses a liquid crystal composition which comprises 1-70wt% of liquid crystal compound shown by formula I, 1-90wt% of liquid crystal compound shown by formula II and 0-70wt% of liquid crystal compound shown by formula III. The liquid crystal composition disclosed by the invention has high optical anisotropy, relatively wide nematic phase temperature range, high clearing point range, relatively low rotary viscosity and proper dielectric anisotropy, thus the liquid crystal composition can realize relatively low box thickness and relatively low drive voltage of a liquid crystal lens; moreover, the liquid crystal composition has the characteristics of fast response, relatively high optical efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of liquid crystal applications, in particular to a liquid crystal composition with high optical anisotropy, high-definition bright spots and low rotational viscosity for manufacturing liquid crystal lenses. Background technique [0002] Devices such as cameras, mobile phone cameras, 3D stereoscopic image displays, and phase modulators often use zoom lenses to enlarge or reduce images to form images. Traditional zoom lenses are equipped with multiple lens groups, and the distance between the lens groups can be changed by moving along the optical axis direction, so that the overall focal length can be changed without affecting the imaging distance. However, this kind of lens requires a long moving distance of the mirror group, resulting in a large mechanical device, slow adjustment, limited focusing range, high price, high energy consumption for device driving and easy damage, etc., and mechanical noise due to...

Problems solved by technology

In view of the fact that the selection and proportioning of each component of the liquid crystal composition determine the various properties of the liquid crystal composition, and the performance parameters of the liquid crystal composition in the prior art have not been able to achieve an ideal combination, therefore, it is necessary to improve the performance of the liquid crystal composition. Further optimization of monomer liquid crystal selection and composition ratio
