Description

一種含有三聯苯與末端含有環烷基的液晶組合物及其應用 A liquid crystal composition containing terphenyl and a terminal cycloalkyl group and its application

本發明涉及一種液晶組合物，具體涉及一種向列相液晶組合物，更具體地涉及一種含有三聯苯與末端含有環烷基的液晶組合物及其應用；本發明所提供的液晶組合物具有快的回應時間和大的對比度，用於液晶顯示器中可提升液晶顯示器的回應速度和對比度。 The present invention relates to a liquid crystal composition, specifically to a nematic phase liquid crystal composition, and more specifically to a liquid crystal composition containing terphenyl and a terminal cycloalkyl group and its application; the liquid crystal composition provided by the present invention has a fast response time and a large contrast ratio, and can be used in a liquid crystal display to improve the response speed and contrast ratio of the liquid crystal display.

近年來，LCD顯示器作為最主流的顯示器，已廣泛用於各種產品中，其中負性液晶顯示器因為其獨有的高透過率特性，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。 In recent years, LCD displays, as the most mainstream displays, have been widely used in various products. Among them, negative liquid crystal displays are widely used in mobile phones, laptops, tablet computers, computer monitors, televisions, etc. due to their unique high transmittance characteristics.

目前，負性液晶顯示器存在的主要劣勢為回應速度較慢、低溫互溶性較差，如何改善回應速度並改善低溫互溶性成為負性液晶顯示器的重要課題，通過研究發現，液晶的旋轉粘度與彈性常數比值降低有助於改善液晶分子的回應速度，液晶的光學各向異性增加有助於降低顯示器面板液晶層厚度，從而改善顯示器的回應速度，但是液晶的低溫互溶性並不理想。 At present, the main disadvantages of negative liquid crystal displays are slow response speed and poor low-temperature miscibility. How to improve the response speed and low-temperature miscibility has become an important issue for negative liquid crystal displays. Through research, it is found that reducing the ratio of the rotational viscosity and elastic constant of liquid crystal helps to improve the response speed of liquid crystal molecules, and increasing the optical anisotropy of liquid crystal helps to reduce the thickness of the liquid crystal layer of the display panel, thereby improving the response speed of the display. However, the low-temperature miscibility of liquid crystal is not ideal.

隨著使用者對液晶顯示器的顯示效果要求越來越高，為了滿足高性能和高品質的顯示效果，液晶面板趨向于使用具有高的阻抗特性的配向層(PI)，而高阻抗的配向層具有更低的離子性，對於改善液晶顯示器的閃爍 (Flicker)、離子型殘像非常有效，但是高阻抗的PI吸附離子的能力較強，容易產生RDC(殘餘電壓)，形成DC型殘像問題。 As users have higher and higher requirements for the display effects of LCDs, in order to meet high performance and high quality display effects, LCD panels tend to use alignment layers (PI) with high impedance characteristics. High impedance alignment layers have lower ionicity and are very effective in improving LCD flicker and ionic afterimages. However, high impedance PI has a strong ability to absorb ions and is prone to generate RDC (residual voltage), resulting in DC afterimage problems.

鑒於此，特提出本發明。 In view of this, this invention is proposed.

本發明旨在提供一種含有三聯苯與末端含有環烷基的液晶組合物，該液晶組合物具有大光學各向異性、低旋轉粘度、大彈性常數，且低溫互溶性好，以此實現改善液晶顯示器回應速度、對比度與使用溫度的目的。該液晶組合物具有負的介電各向異性，用於液晶顯示器中具有更高的透過率和具有改善液晶顯示器閃爍的效果；同時該液晶組合物可以減弱RDC效應，對於改善DC型殘像以及對於殘像恢復非常有效。 The present invention aims to provide a liquid crystal composition containing terphenyl and a cycloalkyl group at the end, which has large optical anisotropy, low rotational viscosity, large elastic constant, and good low-temperature miscibility, thereby achieving the purpose of improving the response speed, contrast and operating temperature of liquid crystal displays. The liquid crystal composition has negative dielectric anisotropy, and has a higher transmittance and an effect of improving the flicker of liquid crystal displays when used in liquid crystal displays; at the same time, the liquid crystal composition can weaken the RDC effect, which is very effective for improving DC-type afterimages and afterimage recovery.

本領域公知，降低組合物的清亮點可以實現降低旋轉粘度的目的，但是隨著清亮點的降低，可導致顯示器使用溫度上限降低，而本發明所提供的的液晶組合物具有高的清亮點、低的旋轉粘度、大的彈性常數和大的光學各向異性，同時可以減弱RDC效應，對於改善DC型殘像以及對於殘像恢復非常有效，從而實現快速回應的液晶顯示器，並且具有更好的顯示效果。此外，本發明所提供的液晶組合物具有良好的低溫互溶性，可以更好的適應於各類使用環境中。 It is well known in the art that lowering the clearing point of the composition can achieve the purpose of lowering the rotational viscosity, but as the clearing point decreases, the upper limit of the display's operating temperature may decrease. The liquid crystal composition provided by the present invention has a high clearing point, low rotational viscosity, a large elastic constant and a large optical anisotropy, and can also weaken the RDC effect, which is very effective in improving DC-type residual images and recovering residual images, thereby achieving a fast-response liquid crystal display with better display effects. In addition, the liquid crystal composition provided by the present invention has good low-temperature miscibility and can be better adapted to various usage environments.

隨著使用者對液晶顯示器的顯示效果要求越來越高，為了滿足高性能和高品質的顯示效果，液晶面板趨向于使用具有高的阻抗特性的配向層(PI)，而高阻抗的配向層具有更低的離子性，對於改善液晶顯示器的閃爍(Flicker)、離子型殘像非常有效，但是高阻抗的PI吸附離子的能力較強，容易產生RDC(殘餘電壓)，形成DC型殘像問題。本發明研發人員發現，加入本發明所提供的通式IV所代表的三聯苯類單晶，可以減弱RDC效應，對於改善DC型殘像以及對於殘像恢復非常有效。 As users have higher and higher requirements for the display effects of liquid crystal displays, in order to meet high performance and high quality display effects, liquid crystal panels tend to use alignment layers (PI) with high impedance characteristics. High impedance alignment layers have lower ionicity, which is very effective in improving flicker and ionic afterimages of liquid crystal displays. However, high impedance PI has a strong ability to adsorb ions, which easily generates RDC (residual voltage) and forms DC afterimage problems. The researchers of the present invention have found that adding the terphenyl single crystal represented by the general formula IV provided by the present invention can weaken the RDC effect, which is very effective in improving DC afterimages and restoring afterimages.

It can be produced by mixing two or more compounds in a conventional method, such as preparing by mixing different components at high temperature and dissolving them in each other, wherein the liquid crystal composition is dissolved in a solvent for the compound and mixed, and then the solvent is distilled out under reduced pressure; or the liquid crystal composition of the present invention can be prepared according to a conventional method, such as dissolving a component with a smaller content in a main component with a larger content at a higher temperature, or dissolving each component in an organic solvent, such as acetone, chloroform or methanol, and then mixing the solutions to remove the solvent to obtain.

本發明所述液晶組合物具有低的旋轉粘度、大的彈性常數與大的光學各向異性，進而具有低的旋轉粘度與彈性常數的比值，更薄的液晶層厚度，其在液晶顯示器中的使用能明顯改善液晶顯示器的回應速度和對比度，本 發明所述液晶組合物具有良好的低溫互溶性，有效改善顯示器使用溫度範圍，同時含有通式IV所代表的單體，可有效改善DC型殘像，有效地改善顯示效果。 The liquid crystal composition of the present invention has low rotational viscosity, large elastic constant and large optical anisotropy, and thus has a low ratio of rotational viscosity to elastic constant and a thinner liquid crystal layer thickness. Its use in a liquid crystal display can significantly improve the response speed and contrast of the liquid crystal display.

Compared with comparative example 1, γ1 of Example 1 is reduced by about 14%, △n is increased by 0.011, and d 2 *γ1/K 22 is reduced by about 39%, that is, the response speed can be improved by about 39% when used in a liquid crystal display. Compared with comparative example 1, Kavg of Example 1 is increased by 1.4, and it is well known in the art that the improvement of Kavg can improve the contrast of a liquid crystal display, so the liquid crystal composition provided by the present invention has a higher contrast.

由以上實施例可知，本發明所提供的液晶組合物具有低的旋轉粘度、更大的光學各向異性和更大的彈性常數，用顯示器中可有效改善液晶顯示器的回應速度與對比度。因此，本發明所提供的液晶組合物適用於液晶顯示裝置，能夠明顯改善液晶顯示器的回應速度特性與對比度特性。 From the above examples, it can be seen that the liquid crystal composition provided by the present invention has low rotational viscosity, greater optical anisotropy and greater elastic constant, and can effectively improve the response speed and contrast of the liquid crystal display when used in the display.

分別將6OSO1B、7OSO1B與3OSO1B、4OSO1B與Host液晶以重量比10%：90%製成混合液晶，各取2g裝在7ml西林瓶中，分別放置於-10℃與-20℃的低溫冰箱中10天后觀察液晶狀態，進行低溫互溶性驗證，具體實驗結果如表31所示：

Figure 110140151-A0305-12-0066-112
Mix 6OSO1B, 7OSO1B, 3OSO1B, 4OSO1B and Host liquid crystal in a weight ratio of 10%:90% to make mixed liquid crystals. Take 2g of each and put them in 7ml vials. Place them in low-temperature refrigerators at -10℃ and -20℃ respectively. After 10 days, observe the state of the liquid crystals and verify the low-temperature miscibility. The specific experimental results are shown in Table 31:
Figure 110140151-A0305-12-0066-112

實驗結果表明6OSO1B與7OSO1B用於混合液晶時低溫互溶性更好，可以在更低溫度下工作，而3OSO1B與4OSO1B低溫互溶性差於6OSO1B與 7OSO1B。由以上結果可推斷通式I化合物R1為C6~C12時具有更好的低溫互溶性，因此，本發明所提供的液晶組合物適用於液晶顯示裝置，能夠明顯擴大液晶顯示器的使用溫度範圍。 The experimental results show that 6OSO1B and 7OSO1B have better low-temperature miscibility when used in mixed liquid crystals and can work at lower temperatures, while 3OSO1B and 4OSO1B have lower low-temperature miscibility than 6OSO1B and 7OSO1B. From the above results, it can be inferred that the compound of formula I has better low-temperature miscibility when R 1 is C 6 ~C 12. Therefore, the liquid crystal composition provided by the present invention is suitable for liquid crystal display devices and can significantly expand the operating temperature range of liquid crystal displays.

將3PGiWO2和3PWP2分別與HOST液晶以重量比5%：95%製成混合液晶，將3PGiWO2+Host、3PWP2+Host、Host分別灌注到TN模式測試盒中，測試RDC。RDC具體測試方法為：在60℃下，加10V直流電壓保持30min，之後撤去電壓10min後測試殘餘電壓。具體實驗結果如表32所示：

Figure 110140151-A0305-12-0067-113
3PGiWO2 and 3PWP2 were mixed with HOST liquid crystal at a weight ratio of 5%:95% to make mixed liquid crystal. 3PGiWO2+Host, 3PWP2+Host, and Host were poured into the TN mode test box to test RDC. The specific RDC test method is: at 60℃, add 10V DC voltage for 30 minutes, then remove the voltage for 10 minutes and test the residual voltage. The specific experimental results are shown in Table 32:
Figure 110140151-A0305-12-0067-113

實驗結果表明3PGiWO2和3PWP2用於混合液晶時，具有更低的RDC。根據以上結果，通式IV所代表的三聯苯類單晶，可以減弱RDC效應，對於改善DC型殘像以及對於殘像恢復非常有效。 Experimental results show that 3PGiWO2 and 3PWP2 have lower RDC when used in mixed liquid crystals. Based on the above results, the terphenyl single crystal represented by general formula IV can weaken the RDC effect and is very effective in improving DC-type afterimages and restoring afterimages.
