Patent number: 10557082Abstract: A liquid crystal composition and use thereof in the liquid crystal display field. The liquid crystal composition includes, in percentages by weight, 5-40% of one or more compounds represented by general formula I, 2-30% of one or more compounds represented by general formula II, and 20-70% of one or more compounds represented by general formula III, and may further include 4-30% of one or more compounds represented by general formula IV and/or 5-25% of one or more compounds represented by general formulas V to IX. The combined use of the above-mentioned compounds can effectively reduce the rotational viscosity of the liquid crystal composition, improve related properties of the mixed liquid crystal, and thus reduce the response time thereof. The liquid crystal composition can be used for a fast-response liquid display in a variety of display modes.Type: GrantFiled: November 27, 2015Date of Patent: February 11, 2020Assignee: BEIJING BAYI SPACE LCD TECHNOLOGY CO., LTDInventors: Maoxian Chen, Haiguang Chen, Shihong Chu, Tianmeng Jiang, Xin Wei, Lin Zhang, Huiqiang Tian, Qinghua Li, Jin Yuan, Yunpeng Guo, Xuehui Su

Patent number: 10414981Abstract: The present invention relates to the technical field of liquid crystal displays, and particularly relates to a liquid crystal composition containing a 2-methyl-3,4,5-trifluorobenzene liquid crystal compound and use thereof, wherein the liquid crystal composition of the present invention comprises, in percentages by weight, 1-50% of one or more compounds represented by general formula I and 10-70% of one or more compounds represented by general formula II, and may further comprise 0-30% of compounds represented by general formula III and/or 6-45% of one or more compounds represented by general formulas IV to XIII. The liquid crystal composition provided by the present invention has a low rotational viscosity and a large elastic constant, is presented as having a shorter response time, and can significantly improve the display effect of a liquid crystal display when applied to TN, IPS and FFS mode displays.Type: GrantFiled: October 23, 2015Date of Patent: September 17, 2019Assignee: BEIJING BAYI SPACE LCD TECHNOLOGY CO., LTDInventors: Maoxian Chen, Haiguang Chen, Shihong Chu, Xin Wei, Xinying Wang, Tianmeng Jiang, Huiqiang Tian, Yunpeng Guo, Lin Zhang, Qinghua Li, Jin Yuan, Xuehui Su
