Description

一種含有三聯苯結構的大彈性常數液晶組合物及其應用 Large elastic constant liquid crystal composition containing terphenyl structure and application thereof

本發明屬於液晶材料技術領域，具體涉及一種含有三聯苯結構的大彈性常數液晶組合物及其應用。 The invention belongs to the technical field of liquid crystal materials, and specifically relates to a large elastic constant liquid crystal composition containing a terphenyl structure and an application thereof.

目前，LCD顯示器作為最主流的顯示器，已廣泛用於各種產品中，其中IPS和FFS模式顯示器因為其獨有的硬屏特性以及非常寬的視角特性，目前廣泛用於手機、筆記型電腦、平板電腦、電腦顯示器、電視等方面。 At present, as the most mainstream display, LCD displays have been widely used in various products. Among them, IPS and FFS mode displays are widely used in mobile phones, notebook computers, and tablets because of their unique hard screen characteristics and very wide viewing angle characteristics. Computers, computer monitors, televisions, etc.

然而，IPS和FFS液晶分子在初始排列時易出現暗態漏光，對比度性能方面明顯劣勢於VA類(MVA、PVA、UV2A、PSVA)顯示器。 However, IPS and FFS liquid crystal molecules are prone to dark-state light leakage during the initial alignment, and the contrast performance is obviously inferior to VA-type (MVA, PVA, UV2A, PSVA) displays.

為了解決上述技術問題，本發明提供一種向列相液晶組合物。所述液晶組合物具有大的彈性常數和快的回應速度，而液晶彈性常數的提高有助於改善液晶分子的排列，避免暗態漏光，用於液晶顯示器中可提升液晶顯示器的對比度。 In order to solve the above technical problems, the present invention provides a nematic liquid crystal composition. The liquid crystal composition has a large elastic constant and a fast response speed, and the improvement of the liquid crystal elastic constant helps to improve the arrangement of liquid crystal molecules, avoid light leakage in the dark state, and can improve the contrast of the liquid crystal display when used in a liquid crystal display.

其中，R4、R5各自獨立地代表C1~C12的直鏈烷基、直鏈烷氧基或C2~C12的直鏈烯基； Wherein, R 4 and R 5 each independently represent a C 1 to C 12 linear alkyl group, a linear alkoxy group or a C 2 to C 12 linear alkenyl group;

A2、A3各自獨立地代表反式1，4-環己基或1，4-亞苯基。 A 2 and A 3 each independently represent trans 1,4-cyclohexyl or 1,4-phenylene.

所述液晶組合物中包含1~35%的通式I所代表的化合物，5~35%的通式II所代表的化合物及20~70%的通式III所代表的化合物。 The liquid crystal composition contains 1 to 35% of the compound represented by general formula I, 5 to 35% of the compound represented by general formula II, and 20 to 70% of the compound represented by general formula III.

本領域公知，提升液晶組合物的清亮點可以實現提升彈性常數的目的，但是隨著清亮點提升，液晶組合物的旋轉粘度增加，從而導致液晶顯示器回應時間變慢。而本發明研究人員發現，通式I所代表的化合物具有非常大的彈性常數，同時在旋轉粘度方面較低，能夠起到提升液晶組合物彈性常數的同時維持旋轉粘度不變，進而滿足液晶顯示器要求的高對比和快速回應的目的。本發明通過添加通式I所代表的化合物增加液晶組合物的彈性常數，同時通過增加通式II類化合物提升液晶組合物的介電各向異性和光學各向異性；為了避免液晶組合物的旋轉粘度過大，進一步增加通式III的化合物。通過合理配置液晶化合物，利用其協同作用，所得液晶組合物一方面具有大的彈性常數，另一方面具有較低的旋轉粘度，從而實現高對比和快速回應的液晶顯示器。 It is well known in the art that increasing the clearing point of the liquid crystal composition can achieve the purpose of improving the elastic constant. However, as the clearing point increases, the rotational viscosity of the liquid crystal composition increases, resulting in a slower response time of the liquid crystal display. The researchers of the present invention have discovered that the compound represented by the general formula I has a very large elastic constant and a low rotational viscosity, which can improve the elastic constant of the liquid crystal composition while maintaining the rotational viscosity unchanged, thereby satisfying the liquid crystal display The purpose of requiring high contrast and quick response. The present invention increases the elastic constant of the liquid crystal composition by adding the compound represented by the general formula I, and at the same time increases the dielectric anisotropy and optical anisotropy of the liquid crystal composition by adding the compound of the general formula II; in order to avoid the rotation of the liquid crystal composition Excessive viscosity further increases the compound of formula III. By rationally disposing the liquid crystal compound and utilizing its synergistic effect, the obtained liquid crystal composition has a large elastic constant on the one hand and a lower rotational viscosity on the other hand, thereby realizing a liquid crystal display with high contrast and fast response.
