Description

具有高透过率的液晶组合物及其显示器件技术领域本发明涉及一种液晶组合物，特别涉及一种电光学目的的用途液晶组合物以及包含该液晶组合物的液晶显示器，特别涉及包含该液晶组合物有源矩阵寻址的显示器和平面内切换（IPS ) 类型的显示器。背景技术液晶显示器（Liquid Crystal Display, LCD) 因其体积小、重量轻、功耗低且显示质量优异而获得了飞速发展，特别在便携式电子信息产品中获得广泛的应用。随着用于便携式计算机、办公应用、视频应用的液晶屏幕尺寸的增加，为了使液晶显示器能够用于大屏幕显示并最终替代了阴极射线管的显示器（Cathode Ray Tube, CRT), 还有几个问题需要解决。如改善视角特性和提高响应速度等。 LCD的视角比较窄是指在离开垂直于液晶盒法线方向观察时，对比度明显下降，对于灰度和彩色显示，视角大时还会发生灰度和彩色反转的现象，严重影响了 LCD的显示质量。视角问题成为 LCD替代 CRT技术的一大障碍。 BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a liquid crystal composition, and more particularly to a liquid crystal composition for electro-optical purposes and a liquid crystal display comprising the liquid crystal composition, and particularly to the inclusion of the liquid crystal composition Liquid crystal compositions are active matrix addressed displays and in-plane switching (IPS) type displays. BACKGROUND OF THE INVENTION Liquid crystal displays (LCDs) have been rapidly developed due to their small size, light weight, low power consumption, and excellent display quality, and are widely used in portable electronic information products. With the increase in the size of liquid crystal screens for portable computers, office applications, and video applications, there are several problems in order to enable liquid crystal displays to be used for large-screen displays and eventually replace cathode ray tube displays (CRTs). Need to be solved. Such as improving the viewing angle characteristics and improving the response speed. The narrow viewing angle of the LCD means that the contrast is significantly reduced when viewed perpendicular to the normal direction of the liquid crystal cell. For grayscale and color display, grayscale and color inversion occur when the viewing angle is large, which seriously affects the LCD. Display quality. The perspective problem has become a major obstacle to LCD replacement CRT technology.

LCD 的视角问题是由液晶的工作原理本身决定的。液晶分子是棒状的，不同的分子排列方式对应着不同的光学各向异性。入射光和液晶分子夹角越小，双折射率就越小；反之双折射率就越大。偏离显示屏法线方向以不同的角度入射到液晶盒的光线与液晶分子指向矢的夹角不同，因此造成不同视角下，有效光程差 A n*d不同。而液晶盒的最佳光程差是按照垂直于盒的法线方向设计的，对于斜入射的光线，最小透射率随夹角的增大而增大，对比度就会下降。当夹角足够大时，甚至会出现对比度反转的现象。目前，已经提出了很多种解决视角问题的方法如：光学补偿弯曲（Optically Compensated Bend, OCB ) 模式、共面转换模式（In-Plane Switching, IPS )、边缘场开关模式（Free Fall Sensor, FFS )和多畴垂面排列模式（Multi-Domain Vertical Alignment, MVA) 等。它们都有各自的优缺点，多畴垂面排列模式具有高对比度和快速响应的特点，但是它需要一个双轴补偿膜和两个椭圆偏振片，因此成本较高， OCB 模式很难用交流电压来保持稳定控制，对1、 G、 B三种单色光的透过率不一样，另外在无场的情况下，液晶盒内的分子是按平行于基板的方向排列的，为了实现弯曲排列，需在盒上加几秒电压进行预置，然后可以在较低的电压下维持这种排列方式，这对使用带来不便。共面转换模式仅需要线偏振片而不需要补偿膜，只是它的响应速度太慢，不能显示快速运动的画面。由于 IPS模式和 FFS模式的制作简单并且有很宽的视角，它们成了能够改善视角特性并实现大面积显示的最有吸引力的办法。上世纪 70年代初，已经对均匀排列的和扭曲排列的、向列液晶 IPS模式的基本的电光特性进行了实验性的研究，其特点是一对电极制作在同一基板上，而另一个基板上没有电极，通过加在这一电极间的横向电场来控制液晶分子的排列，因此也可以称这种模式为横向场模式。在 IPS模式中向列液晶分子在两基板间均匀平行排列，两偏振片正交放置。 IPS模式在不加电场时，入射光被两个正交的偏振片阻断而呈暗态，加电场时液晶分子发生转动造成延迟，于是有光从两个正交的偏振片漏出，其显示原理如图 1所示。 The viewing angle of the LCD is determined by the working principle of the liquid crystal itself. The liquid crystal molecules are rod-shaped, and different molecular arrangements correspond to different optical anisotropies. The smaller the angle between the incident light and the liquid crystal molecules, the smaller the birefringence; on the contrary, the larger the birefringence. The angle of light incident on the liquid crystal cell at different angles from the normal direction of the display screen is different from that of the director of the liquid crystal molecules, so that the effective optical path difference A n*d is different at different viewing angles. The optimum optical path difference of the liquid crystal cell is designed perpendicular to the normal direction of the cell. For obliquely incident light, the minimum transmittance increases with the increase of the angle, and the contrast decreases. When the angle is large enough, even the contrast reversal occurs. At present, many methods for solving perspective problems have been proposed, such as: Optically Compensated Bend (OCB) mode, In-Plane Switching (IPS), and Free Fall Sensor (FFS). And Multi-Domain Vertical Alignment (MVA). They all have their own advantages and disadvantages. The multi-domain vertical alignment mode has high contrast and fast response characteristics, but it requires a two-axis compensation film and two ellipses, so the cost is high, and the OCB mode is difficult to use AC voltage. To maintain stable control, the transmittances of the three monochromatic lights of 1, G, and B are different. In addition, in the absence of the field, the molecules in the liquid crystal cell are arranged in a direction parallel to the substrate, in order to achieve the bend. The arrangement of the songs requires a few seconds of voltage on the box to be preset, and then the arrangement can be maintained at a lower voltage, which is inconvenient for use. The coplanar conversion mode requires only a linear polarizer without the need for a compensation film, but its response speed is too slow to display a fast moving picture. Since the IPS mode and the FFS mode are simple to manufacture and have a wide viewing angle, they are the most attractive way to improve the viewing angle characteristics and achieve large-area display. In the early 1970s, experimental studies were conducted on the basic electro-optical properties of uniformly aligned and twisted, nematic liquid crystal IPS modes, characterized by a pair of electrodes fabricated on the same substrate and on the other substrate. Without the electrode, the alignment of the liquid crystal molecules is controlled by the transverse electric field applied between the electrodes, so this mode can also be called the transverse field mode. In the IPS mode, the nematic liquid crystal molecules are uniformly arranged in parallel between the two substrates, and the two polarizing plates are placed orthogonally. In the IPS mode, when no electric field is applied, the incident light is blocked by two orthogonal polarizers and is in a dark state. When an electric field is applied, the liquid crystal molecules are rotated to cause a delay, so that light leaks from two orthogonal polarizers, and the display thereof The principle is shown in Figure 1.

IPS模式可以使用正性液晶或负性液晶，因为透光率饱和电压随 Δ ε的绝对值的增大而减小，所以正性液晶的透光率饱和电压要比负性液晶的低，并且响应速度更快，但是负性液晶要比正性液晶的透光率要好些。原因如下图 2 所示，主要是由于正负液晶在电场下的转动不同所致。三星电子在 2008年 2月 20日申请的专利 CN101270287A曾今公开过一种正负性液晶混配的方案，但是只是提到在负性液晶中加入正性组分，液晶整体仍然为负性。智索株式会社在 2000年 11月 21 日申请专利 JP2002156619A中也曾今公开过一种正负液晶混配的实验方案，以上两个方案均没有详细提到正性液晶中掺杂少量负性液晶单体对 IPS液晶显示的透过率的提升效果。发明内容本发明的目的是提供一种应用于 IPS 模式中的液晶组合物，所述液晶组合物将一种或者多种负性液晶单体掺杂在正介电各项异性的 IPS 液晶中，令人惊奇的发现，通过此种掺杂模式，能够在维持 Δ ε不变的情况下，增大液晶的 ε// 和 ε丄，其中 Δ ε=_ε// -ε丄， Δ ε为介电各向异性， ε//为平行于分子轴方向上的介电常数， ε丄为垂直于分子轴方向上的介电常数， Δ ε>0 的液晶称为正性液晶，The IPS mode may use a positive liquid crystal or a negative liquid crystal because the transmittance saturation voltage decreases as the absolute value of Δ ε increases, so the transmittance saturation voltage of the positive liquid crystal is lower than that of the negative liquid crystal, and The response speed is faster, but the negative liquid crystal is better than the positive liquid crystal. The reason is as shown in Figure 2, mainly due to the difference in the rotation of the positive and negative liquid crystals under the electric field. The patent CN101270287A, which was applied by Samsung Electronics on February 20, 2008, has disclosed a positive-negative liquid crystal compounding scheme, but only mentions that a positive component is added to the negative liquid crystal, and the liquid crystal as a whole is still negative. In the application for patent JP2002156619A on November 21, 2000, Zhisuo Co., Ltd. also disclosed an experimental scheme for positive and negative liquid crystal compounding. The above two schemes do not mention in detail the doping of a small amount of negative liquid crystal in positive liquid crystal. The effect of monomer on the transmittance of IPS liquid crystal display. SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid crystal composition for use in an IPS mode, wherein the liquid crystal composition is doped with one or more negative liquid crystal monomers in an IPS liquid crystal of positive dielectric anisotropy, Surprisingly, it is found that by this doping mode, the ε// and ε丄 of the liquid crystal can be increased while maintaining Δ ε, where Δ ε = _ε // - ε 丄, Δ ε Electrical anisotropy, ε// is a dielectric constant parallel to the molecular axis, ε丄 is a dielectric constant perpendicular to the molecular axis, and Δ ε>0 is called a positive liquid crystal.

Δ 8<0的液晶称为负性液晶。根据 IPS模式的透过率公式 transmittance (透过率） °^Δε/ε丄（表示 "反比例"关系）。通过将上述负性液晶单体掺杂正介电各项异性的 IPS 液晶中，可以使得到的液晶组合物在保持正性 IPS 液晶的快响应，低驱动电压、较高的清亮点、较低的旋转粘度、合适的光学各向异性以及合适的介电各向异性等优点的同时，还极大地提高液晶显示的透过率，与现有的正介电各项异性的 IPS 液晶相比透过率可提高 5~20%。为了解决上述问题，本发明提供了一种正介电各向异性的液晶组合物，所述液晶组合物，包含： The liquid crystal of Δ 8 < 0 is referred to as a negative liquid crystal. According to the IPS mode, the transmittance formula is transmittedtance (transmission rate) °^Δε/ε丄 (indicating the "inverse ratio" relationship). By doping the above negative liquid crystal monomer into the positive dielectric anisotropic IPS liquid crystal, the obtained liquid crystal composition can maintain a fast response of the positive IPS liquid crystal, a low driving voltage, a high clearing point, and a low Rotational viscosity, suitable optical anisotropy, and suitable dielectric anisotropy The advantages are also greatly improved the transmittance of the liquid crystal display, and the transmittance can be increased by 5 to 20% compared with the conventional positive dielectric anisotropy IPS liquid crystal. In order to solve the above problems, the present invention provides a positive dielectric anisotropy liquid crystal composition, the liquid crystal composition comprising:
