Liquid crystal mixture with low diffusivity and application thereof

Abstract

The invention provides a liquid crystal mixture with low diffusivity; the liquid crystal mixture includes a component 1 with low diffusivity and low viscosity, a component 2 with low diffusivity and high dielectric constant, a component 3 with low diffusivity and high-definition bright point, and / or a component 4 with high optical anisotropy. The liquid crystal mixture provided by the invention has good low diffusivity, and is especially suitable for production of TN, IPS and FFS type liquid crystal display devices by a novel ODF liquid crystal injection preparation process.

Description

technical field [0001] The invention relates to a liquid crystal mixture and its application, and belongs to the technical field of liquid crystal materials. Background technique [0002] With the maturity of TFT LCD technology, liquid crystal displays have gradually developed into mainstream products in the field of information display. Compared with traditional cathode ray tubes, TFT LCD has obvious advantages in power consumption, display range, resolution, contrast, viewing angle and response speed. With the continuous improvement of TFT LCD technology, its service life has reached more than 30,000 hours. In addition, TFT LCD is not only thin and light in size and beautiful in appearance, but also saves space and is easy to carry. It has been widely used in display devices such as mobile phones, computers, LCD TVs, and cameras. Its thinness also gradually leads people into the era of paperless office. [0003] With the expansion of the application field of TFT liquid ...

Problems solved by technology

[0004] Although the ODF process will bring many advantages, compared with the traditional vacuum infusion process, after ODF injects liquid crystals, due to the small size of the panel, the liquid crystal diffusion space will become smaller. It has been in contact with the liquid crystal before being cured, and the chemical composition of the frame glue is easy to interact with the chemical composition of the liquid crystal material, forming pollution to the liquid crystal, resulting in a decrease in the voltage retention rate of the liquid crystal, which in turn brings a series of display defects
