Definitions

  • the present invention relates to a liquid crystal composition having high voltage holding ratio, good UV resistance and high temperature reliability, large maximum absolute transmittance, and a liquid crystal display device comprising the liquid crystal composition, especially transmission Type liquid crystal display device.
  • Liquid crystal display devices are used in many fields of information display, for direct view displays and for projection type displays.
  • the liquid crystal display device is classified into a reflection type using natural light, a transmission type using a backlight, and a semi-transmissive type using both natural light and backlight depending on the type of the light source.
  • the type of display mode it is divided into PC (phase change), TN (twist nematic), STN (super twisted nematic), ECB (electrically controlled birefringence), OCB (optically compensated bend), IPS (in-plane switching), VA (vertical alignment).
  • the components operating in the TN and STN modes use positive dielectric anisotropy liquid crystals, while the components operating in the ECB and VA modes use negative dielectric anisotropy liquid crystals.
  • the IPS mode can use positive dielectric anisotropy liquid crystals. Negative dielectric anisotropic liquid crystals are used.
  • the dielectric anisotropic liquid crystal composition having a large absolute value can lower the basic voltage value of the liquid crystal display device, lower the driving voltage, and further reduce the power consumption.
  • a liquid crystal composition having a small viscosity can improve the response speed of the liquid crystal display device.
  • the response speed of the liquid crystal display device is fast, it can be applied to an animated display.
  • the liquid crystal composition is injected into the liquid crystal cell of the liquid crystal display device, the injection time can be shortened, and workability can be improved.
  • the transmissive liquid crystal display device adjusts the transmittance of the backlight by liquid crystal molecules to achieve a display effect, and the large optical transmittance is a performance pursued by the liquid crystal display device.
  • the maximum optical transmittance greater brightness and higher contrast can be obtained.
  • the LCD screen In a strong light environment (such as in the sun), the LCD screen will be whitened, and the content on the LCD screen cannot be seen. At this time, by increasing the brightness of the screen, the display content can be more clearly displayed.
  • the stability (UV) stability and thermal stability of the liquid crystal composition are related to the life of the liquid crystal display device. Increasing the ultraviolet (UV) stability and thermal stability of the liquid crystal composition can extend the life of the liquid crystal display device.
  • the prior art discloses a liquid crystal composition having low power consumption and fast response, such as the patent document CN102858918A, but there are environmental problems in the prior art (such as the use of chlorine-containing compounds) and short service life (such as poor UV or thermal stability). Low contrast (such as white screen display in daylight), and the inability to balance the requirements of appropriate optical anisotropy, proper dielectric anisotropy, high voltage retention, UV stability and high temperature stability in LCD TVs, tablets, etc. The performance balance problem cannot meet all aspects of the indicators at the same time.
  • Liquid crystal materials are an important part of liquid crystal displays. At present, global liquid crystal displays have great market demand and are mostly used in electronic and electrical products, but their life cycle is short. In the short life cycle, there are naturally problems such as waste pollution.
  • waste pollution nowadays, when environmental protection issues are increasingly valued by the community, if you can control from the source, that is, choose environmentally friendly green materials in the process of liquid crystal material modulation. Greatly reduce the environmental cost of disposing of a waste LCD display. Therefore, it is often necessary to make creative work in the preparation of liquid crystal materials which are suitable in all aspects and which are economical and environmentally friendly.
  • the invention utilizes a saturated alkyl-neutral monomer to improve the reliability of the liquid crystal to achieve high voltage holding ratio, good UV stability, and higher maximum absolute transmittance.
  • the present invention does not use a chlorine-containing monomer to achieve a green environmentally-friendly technical effect, and at the same time compensates for the reduction of dielectric and clearing points by increasing the content of neutral and medium-polar monomers.

Description

液晶组合物及其液晶显示器件 技术领域
本发明涉及一种具有高的电压保持率、较好的抗UV性能和高温可靠性、大的最大绝对透过率的液晶组合物，以及包含所述液晶组合物的液晶显示器件，尤其是透射型液晶显示器件。
背景技术
液晶显示器件用于信息显示的众多领域，用于直视显示器也用于投影型显示器。
液晶显示器件根据光源的类型分为利用自然光的反射型、利用背光的透过型、以及利用自然光和背光两种光源的半透过型。
根据显示模式的类型分为PC(phase change，相变)、TN(twist nematic，扭曲向列)、STN(super twisted nematic，超扭曲向列)、ECB(electrically controlled birefringence，电控双折射)、OCB(optically compensated bend，光学补偿弯曲)、IPS(in-plane switching，共面转变)、VA(vertical alignment，垂直配向)等类型。工作在TN、STN模式的元件使用正介电各项异性液晶，而工作在ECB、VA模式的元件使用负介电各项异性液晶，IPS模式既可使用正介电各项异性液晶，也可使用负介电各项异性液晶。
随着技术的发展，人们对显示器件的要求在不断提高，如趋于完美的现实效果、大介电、低功耗、高对比度、快响应、寿命长等，这也从侧面要求液晶材料不断提升性能参数。
绝对值大的介电各向异性的液晶组合物，能够降低液晶显示器件的基础电压值、降低驱动电压，并能进一步降低消耗电功率。
粘度小的液晶组合物，可提高液晶显示器件响应速度。当液晶显示器件的响应速度快时，可适用于动画显示。另外，向液晶显示器件的液晶盒内注入液晶组合物时，可缩短注入时间，能够提高作业性。
透射型液晶显示器件是通过液晶分子来调节背光的透过率以达到显示的效果，而大的光学透过率，是液晶显示器件所追求的性能。通过提高最大光学透过率，可以获得更大的亮度，更高的对比度。在光线强烈的环境下(如阳光下)，液晶屏幕就会泛白，无法看清液晶屏幕上的内容，而此时通过提高屏幕的亮度，就可以使得显示内容得到更加清晰的展现。
此外，液晶组合物对紫外线(UV)的稳定性及热稳定性与液晶显示器件的寿命相关联。提高液晶组合物对紫外线(UV)的稳定性及热稳定性可延长液晶显示器件的寿命。
因此，通过液晶材料的优化，来提高最大光学透过率、紫外线(UV)稳定性及热稳定性，是本领域技术人员的努力方向。
现有技术公开了具有低功耗，快响应的液晶组合物，如专利文献CN102858918A，但现有技术中存在环保问题(如含氯化合物的使用)、使用寿命短(如UV或热稳定性差)、对比度低(如日光下显示屏幕泛白)，以及无法兼顾在液晶电视、平板电脑等要求适当的光学各向异性、适当的介电各项异性、高电压保持率、抗UV稳定及高温稳定的性能均衡问题，不能同时满足各方面指标。
从液晶材料的制备角度出发，液晶材料的各项性能是互相牵制影响的，某项性能指标的提升可能会使其他性能发生变化。因此，制备各方面性能都合适的液晶材料往往需要创造性劳动。
液晶材料是液晶显示器的重要组成部分，而目前全球液晶显示器具有很大的市场需求，多用于电子电器产品中，但其生命周期较短。较短的生命周期自然存在废弃污染等问题，在如今绿色环保问题日益受到社会各界的重视的情况下，如若能从源头控制，即在液晶材料的调制过程中选择环保绿色的材质，就能极大降低处理废弃液晶显示器时所付出的环境代价。因此，制备各方面性能都合适，又经济、绿色环保的液晶材料往往更需要创造性劳动。
本发明利用饱和烷基类中性单体来提高液晶的可靠性，以达到高的电压保持率、较好的抗UV稳定性，以及更高的最大绝对透过率。此外，本发明不使用含氯单体以达到绿色环保的技术效果，同时通过增加中性、中极性单体的含量来弥补介电及清亮点的降低问题。
本发明的目的是提供一种液晶组合物，其具有大的最大绝对透过率、高的电压保持率、较好的抗UV性能和高温可靠性，以及适宜的光学各向异性、适宜的介电各向异性、较高的清亮点等特性，且又绿色环保。本发明的其他目的是提供一种液晶显示器件，尤其是透射型液晶显示器件，其具有最大绝对透过率高、电压保持率高、抗UV性能和高温可靠性好、节能环保等特性。
发明内容
本发明的目的是提供一种具有大的最大绝对透过率、高的电压保持率、较好的抗UV性能和高温可靠性，以及适宜的光学各向异性、适宜的介电各向异性、较高的清亮点等特性，且又绿色环保的液晶组合物。
本发明的其它目的是提供一种液晶显示器件，尤其是透射型液晶显示器件，其包含具有大的最大绝对透过率、高的电压保持率、较好的抗UV性能和高温可靠性，以及适宜的光学各向异性、适宜的介电各向异性、较高的清亮点等特性，且又绿色环保的液晶组合物，使得液晶显示器件具有最大绝对透过率高、电压保持率高、抗UV性能和高温可靠性好、节能环保等特性。
