Description

一种液晶显示器件
技术领域
本发明涉及液晶显示技术领域。更具体地，涉及一种液晶显示器件。
背景技术
目前，液晶化合物的应用范围拓展的越来越广，其可应用于多种类型的显示器、电光器件、传感器等中。用于上述显示领域的液晶化合物的种类繁多，其中向列相液晶应用最为广泛。向列相液晶已经应用在无源TN、STN矩阵显示器和具有TFT有源矩阵的系统中。
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，但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，降低驱动电压以降低功耗等方面。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。
作为液晶材料，需要具有良好的化学和热稳定性以及对电场和电磁辐射的稳定性。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温度范围、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、高电荷保持率以及低蒸汽压等性能。
对于动态画面显示应用，消除显示画面残影和拖尾，要求液晶具有很快的响应速度，因此要求液晶具有较低的旋转粘度γ1；另外，对于便携式设备，为了降低设备能耗，希望液晶的驱动电压尽可能低；而对于电视等用途的显示器来说，对于液晶的驱动电压要求不是那么的低。
液晶化合物的粘度，尤其是旋转粘度γ1直接影响液晶加电后的响应时间，不管是上升时间(ton)还是下降时间(toff)，都与液晶的旋转粘度γ1成正比关系，上升时间(ton)由于与液晶盒和驱动电压有关，可以通过加大驱动电压的方法与降低液晶盒盒厚来调节；而下降时间(toff)与驱动电压无关，主要是与液晶的弹性常数与液晶盒盒厚有关，盒厚的趋薄会降低下降时间(toff)，而不同显示模式下，液晶分子的运动方式不一样，TN、IPS、VA三种模式分别与平均弹性常数K、扭曲弹性常数、弯曲弹性常数成反比关系。
依照液晶连续体理论，各种不同的液晶在外力(电场、磁场)作用下发生形变后，会通过分子间的相互作用，会“回弹”回原来的形状；同样的，液晶也是由于分子间的相互作用力形成“粘度”。液晶分子的微小变化，会使液晶的常规参数性能发生明显的变化，这些变化有的是有一定规律的，有的似乎不易找到规律，对于液晶分子间的相互作用也会产生明显的影响，这些影响非常微妙，至今也没有形成很完善的理论解释。
液晶的粘度与液晶分子结构有关，研究不同液晶分子形成的液晶体系的粘度与液晶分子结构之间的关系是液晶配方工程师的重要任务之一。
液晶面板能耗高的原因是只有大约5％左右的背光能够穿透显示器件，而被人眼捕获，绝大部分光是被“浪费”了的。如果能够开发出光穿透率高的液晶，即能够降低背光强度，从而实现节省能耗的目的，延长设备的使用时间。
因此，需要提供一种新的液晶显示器件。

实施例1与对比例1，使用相同的液晶组合物，但采用不同的液晶显示器件设计方案；实施例1与对比例2，采用相同的液晶显示器件设计方案，但使用不同的液晶组合物。将上述各实施例及对比例测试透过率，对比例1的透过率为5.4％，对比例2的透过率为5.3％，实施例1和实施例2的透过率均为6％，较对比例1、对比例2分别提高了11％和13％。通过使用本发明提供的液晶组合物与液晶显示器件的搭配，获得更高的透过率，从而达到液晶显示器件具有较高的亮度或者具有节能省电的效果。
本发明实施例提供的液晶组合物具有良好的对光和热的稳定性，较低的粘度，可以调节得到较为宽泛的折射率、较高的清亮点(很宽的使用温度范围)，尤其是具有较高的光的穿透率，因而显示器件具有较高的亮度或是具有节能省电的效果。本发明实施例提供的液晶显示器件具有较高的光的透过率，使更多的背光穿透液晶显示器件，使液晶显示器件具有较高的亮度。或者，因为透过率的提高，使用更少的背光可以达到与现有技术相同的亮度，更少的背光意味着更低的电源消耗。也就是说，本发明提供的液晶显示器件具有较高的亮度或者具有节能省电的效果。

如图3所示，与对比例1不同，实施例1的液晶组合物在电场作用下，具有更好的排列方向，其排列方向更趋向于水平方向排列，提高了液晶组合物对光的偏转作用。
如图4所示，在图3的基础上进一步详细的表明了在狭缝电极结构的不同位置具有不同的透过率，在对比例的透过率较低的位置，实施例具有更高的透过率，总体上实施例达到了更高的透过率。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本发明的技术方案所引伸出的显而易见的变化或变动仍处于本发明的保护范围之列。
