[0008] 随着九十年代初TFT技术的成熟,彩色液晶平板显示器迅速发展,不到10年的时间,TFT-LCD迅速成长为主流显示器,运与它具有的优点是分不开的。 [0008] With the maturation early nineties TFT technology, the rapid development of the color liquid crystal flat panel displays, less than 10 years, TFT-LCD display rapid growth of the mainstream, and it has the advantage that transport is inseparable. 其优点主要分为5点: The advantage is divided into five points:

[0009] -、使用特性好。 [0009] - good usage characteristics. 低压应用,低驱动电压;平板化,又轻薄,节省了大量原材料和使用空间;低功耗;显示质量从最简单的单色字符图形到高分辨率,高彩色保真度,高亮度, 高对比度,高响应速度的各种规格型号的视频显示器;其显示方式有直视型,投影型,透视式和反射式等多种显示方式。 Application of low voltage, low driving voltage; flat-panel, and very thin, saving a lot of raw materials and the use of space; low power consumption; display quality from the most simple monochrome character pattern to a high resolution, high color fidelity, high brightness, high contrast, various models of high response speed of a video display; display mode has a variety of direct-view display, projection, perspective and reflective like.

[0010] 二环保特性好。 [0010] two good environmental characteristics. TFT-LCD无福射、无闪烁,对使用者的健康无损害,特别是TFT-LCD 电子书刊的出现,将把人类带入无纸办公、无纸印刷时代,引发人类学习、传播和记栽文明方式的革命。 TFT-LCD no blessing shoot, no flicker, no harm to the health of users, especially the emergence of TFT-LCD e-books, will mankind into a paperless office, paperless printing times, lead to human learning, communication, and remember planted revolution civilized way.

[0011] S适用范围宽:从-20°c到50°C的溫度范围内都可W正常使用,经过溫度加固处理的TFT-LCD低溫工作溫度可达到零下80°C。 [0011] S broad scope of application: from -20 ° c to a temperature in the range of 50 ° C can be used normally W, the temperature after the TFT-LCD reinforcement low working temperature can reach minus 80 ° C. 既可作为移动终端显示,台式终端显示,又可W作大屏幕投影电视,是性能优良的全尺寸视频显示终端。 As the mobile terminal can display a desktop terminal display, but also for large-screen projection TV W, excellent performance is the full-size video display terminal.

[0012] 四制造技术的自动化程度高。 [0012] four high degree of automated manufacturing technology.

[0013] 五TFT-LCD易于集成化和更新换代。 [0013] V. TFT-LCD easy integration and replacement.

[0014] 由上所述液晶平板显示器的主要特点,因此对液晶平板显示器所用的液晶材料品质特性也提出了更高的要求,液晶组合物本身应具有高电荷保持率、高电阻率、低离子浓度、低功耗、低旋转粘度。 [0014] The main features of the liquid crystal panel display, so the quality characteristics of the liquid crystal material used in liquid crystal flat panel display also requires a higher liquid crystal composition itself should have a high charge holding ratio, high resistivity, low ion concentration, low power, low rotational viscosity.

[0015] 作为液晶材料,需要具有良好的化学和热稳定性W及对电场和电磁福射的稳定性。 [0015] As the liquid crystal material is required to have good chemical and thermal stability and W Four electric and electromagnetic emission stability. 而作为薄膜晶体管技术(TFT-LCD)用液晶材料,不仅需要具有如上稳定性外,还应具有较宽的向列相溫度范围、合适的双折射率各向异性、非常高的电阻率、良好的抗紫外线性能、高电荷保持率W及低蒸汽压等性能。 As a thin film transistor technology (TFT-LCD) with liquid crystal material is required to have not only the above stability, but also have a wider temperature range of a nematic phase, a suitable birefringence anisotropy, a very high resistivity, good UV resistance, high charge holding ratio W, and low vapor pressure properties.

[0016] 对于薄膜晶体管技术(TFT-LCD)应用领域,近年来市场虽然已经非常巨大,技术也逐渐成熟,于此同时,由于液晶材料技术的不断进步,人们对显示技术的要求也在不断的提高,尤其是在实现快速响应,降低驱动电压W降低功耗等方面。 [0016] The thin film transistor technology (TFT-LCD) applications, although in recent years, the market has been very great, mature technology, the same time, since the liquid crystal material technology continues to progress, it requires the display technology is constantly improved, especially in terms of fast response, reduce the driving voltage W to reduce power consumption.

[0017] 液晶材料作为液晶显示器重要的光电子材料之一,对改善液晶显示器的性能发挥重要的作用。 [0017] The liquid crystal material is a liquid crystal display as one of the important optoelectronic material, to improve the performance of liquid crystal displays play an important role. 任何的显示用液晶组合物都要求有较宽的液晶态溫度,较高的稳定性,比较适合的粘度,对电场有较快的响应速度。 Any liquid crystal composition for display are required to have a broad liquid crystalline temperature, high stability, more suitable viscosity, the electric field has a faster response speed. 但是目前为止还没有任何单一的液晶材料单独用在液晶显示器中,而不用开发其它性能特性的组合物就能够满足性能要求。 However, so far no single crystal material in liquid crystal displays used alone, without the development of other performance characteristics of the compositions can meet the performance requirements. 因此,不断开发新的性能优异的液晶材料对液晶显示发展具有重要的意义。 Therefore, to develop new high performance liquid crystal material is of great significance for the development of a liquid crystal display. 液晶在使用过程中,会不断受到光福射W及热福射的影响,同时其在制作过程中也不可避免的受到光与热的接触,运种未下的接触会造成液晶分子在杂质方面的变化,从而影响到液晶错定能力的变化,进而影响面板的显示效果,虽则面板技术的突飞猛进,OL邸较LCD在运方面有着突出的优势,本发明针对液晶在生产制作W及使用过程受到光W及热的影响,提出了相应的解决方案,经过实验表明,通过改善,其信赖性程度大幅提升,可W避免液晶材料在接触不同波段W及高溫时受到的不良影响 Liquid crystal during use, will continue to be affected by heat and light W emitted fu-fu emitted, while it is inevitably subject to light and heat in the production process of the contact, the contact is not the kind of operation will cause the liquid crystal molecules in terms of impurities the change, which affects the change in liquid crystal wrong given ability, thereby affecting the display panel, though rapid panel technology, OL Di than the LCD has outstanding advantages in transportation aspect, the present invention is directed to a liquid crystal being in manufacturing production W and use Effects of W light and heat, corresponding solutions proposed, after the experiment show that, by improving its degree of reliability dramatically, W may be subjected to the liquid crystal material to avoid the adverse effect upon contact with high-temperature and different wavelengths W
