Abstract

The invention discloses a liquid crystal medium and an application thereof in liquid crystal display. The liquid crystal medium has positive dielectric anisotropy. The liquid crystal medium disclosed by the invention is excellent in property, has the property that the refractive index is higher than 0.100, and is suitable for a liquid crystal panel which is thick in low box and fast in response; meanwhile, the liquid crystal has high K value property; the Domian phenomenon of poor display of the liquid crystal can be improved; and the composition disclosed by the invention has a wide application prospect and application value in liquid crystal display, and is especially suitable for an active matrix TN-TFT, IPS-TFT, and an FFS-TFT display with fast response, thick low box and high display picture.

Description

technical field [0001] The present invention relates to a liquid crystal medium and a liquid crystal display containing the liquid crystal medium, in particular to a display addressed by an active matrix, and the TN mode and IPS mode in this driving mode. It also relates to displays driven by other known means. technical background [0002] At present, the application range of liquid crystal compounds is expanding more and more widely, and it can be applied to various types of displays, electro-optic devices, sensors, and the like. There are various types of liquid crystal compounds used in the above-mentioned display fields, among which nematic liquid crystals are most widely used. Nematic liquid crystals have been used in passive TN, STN matrix displays and systems with TFT active matrix. [0003] For the application field of thin film transistor technology (TFT-LCD), although the market has been huge in recent years and the technology has gradually matured, people's req...
