Problems solved by technology

[0005] 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 curing, 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

Abstract

The invention provides a low-diffusivity liquid crystal mixture which is particularly suitable for producing TN, IPS and FFS type liquid crystal display devices in a novel ODF liquid crystal injection process.

Description

[0001] This invention is a divisional case of the prior invention patent with application number 201711047421X, and the application date is 2017.10.31. This divisional case is written based on the embodiments 5, 6 and 8 of the parent case specification. technical field [0002] The invention relates to a liquid crystal mixture and its application, and belongs to the technical field of liquid crystal materials. Background technique [0003] 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 e...
