Problems solved by technology

At present, a TN first extremely small liquid crystal composition can simultaneously have good low temperature (less than -50°C) reliability, wide temperature (-50°C--85°C) operation, and low threshold voltage (1.0v--1.5v) , and the comprehensive properties such as low temperature and fast response have not been reported, this is because the optimization of various performance parameters of mixed liquid crystal materials is contradictory to each other, and is restricted and influenced by each other.

Abstract

The invention discloses a TN (Twisted Nematic) first polar small liquid crystal composition. The composition comprises compounds shown as formulae I, II and III in the specification. According to the invention, a liquid crystal mixture is obtained by using liquid crystal compounds with good low-temperature property and great dielectric constant. The liquid crystal mixture disclosed by the invention has the advantages of good low-temperature reliability, quick response and low threshold voltage.

Description

technical field [0001] The invention relates to a twisted nematic phase (TN, Twisted Nematic) first extremely small liquid crystal composition. Background technique [0002] In the liquid crystal era where the pace of technological innovation is accelerating and the market is expanding, people are pursuing more perfect display effects. An ideal liquid crystal display element should have high brightness, high contrast, high resolution, large display capacity, full-color display, low voltage drive, and low power consumption. The display device itself is integrated with the drive circuit and has high reliability. , long life and thin and light components. [0003] With the development of liquid crystal displays, the requirements for the performance of liquid crystal materials are getting higher and higher. The TN first extremely small liquid crystal has a wide range of applications, such as in the display of vehicles, electric meters, and light valves. At present, a TN first...
