with the improvement of china bearings manufacturing processes and reduce costs

 With an array of thin-film transistor  drive rapid development technology, in recent years, not only occupy  portable notebook computers and other high-end display market, and with the improvement of manufacturing processes and reduce costs, currently has a desktop monitor challenge. Since the china bearings ‍thin film transistor array of the liquid crystal molecules directly driven, eliminating the effect of cross-talk, thus roller bearing‍ showing a large capacity of information; with the use of low-viscosity liquid crystal material, the response speed is greatly improved to meet the needs of video image display. Therefore, than type,  type has been a qualitative leap in the 21st century to become one of the most promising display technology.

 also use TN-type electro-optic effect principle, but  liquid crystal material is different from traditional liquid crystal material. In addition to the requirements to have good physical Tapered bearing‍ china bearings and chemical stability, wide operating temperature range outside,  liquid crystal material must have the following characteristics:

(1) low-viscosity, 20 ℃ viscosity should be less than 35mPa8226; s, in order to meet the needs of fast response;

(2) the lower threshold voltage in order to achieve low-voltage drive, the purpose of reducing the power consumption;

(3) a high voltage holding ratio  which means that the liquid crystal material must have high resistivity, typically requires at least a large‍
