Description

一种配向膜材料及相应的液晶面板
技术领域
本发明涉及液晶显示技术，尤其涉及一种配向膜材料及相应的液晶面板
背景技术
TN（Twisted nematic，扭曲向列型）或STN（Super twisted nematic，超扭曲向列型）液晶显示器所用的液晶为正型液晶，未加电时液晶分子长轴平行于基板表面。基板表面液晶分子的排列方向由配向层（Alignment layer，材质通常为Polyimide）的摩擦方向（Rubbing direction）决定，两基板表面配向方向垂直，所以从一个基板表面到另一个基板表面，液晶层的分子呈连续扭转排列状态。当施加电压之后，液晶分子的长轴将倾向于沿电场的方向排列。TN/STN型液晶显示器的缺点是可视角小，在大视角下的亮度差异和色差严重，需要通过补偿膜对此进行改善，从而提高了显示器的制造成本。
MVA（Multi-domain vertical alignment，多象限垂直配向型）TFT-LCD很好的解决了TN/STN显示器视角限制的问题，它采用负型液晶与垂直配向膜材料。未施加电压时，液晶分子长轴均垂直于基板表面，施加电压会使液晶分子倾倒，液晶分子长轴倾向于沿垂直电场方向排列。为了解决视角问题，一个亚像素被分成多个区域，使液晶分子朝不同的方向倾倒，让显示器从不同的方向看到的效果趋于一致。在一个亚像素内使不同区域的液晶分子导向不同的方向有多种方法。第一种是通过曝光显影的办法在LCD的上下基板制作出Bump（隆起物），使Bump周围的液晶分子产生一定的预倾角，引导液晶分子朝固定方向倾倒；第二种是在上下基板上形成具有一定图案的ITO（Indium Tin Oxide, 氧化铟锡）像素电极，由此产生的电场具有一定的倾斜角度，从而控制不同区域的液晶分子的导向，此技术被称为PVA（Patterned vertical alignment，垂直取向构型）技术；第三种是在LCD基板的TFT侧形成ITO slit（裂缝），另一侧为Full ITO，在液晶介质中添加可聚合的monomer（单体），先通过电场使液晶分子倾倒，同时用紫外光照射面板使monomer聚合形成具有引导液晶分子倾倒的聚合物颗粒，沉积在基板表面起到配向的作用，这种技术成为PSVA（Polymer stabilized vertical alignment，聚合物稳定垂直对齐）技术。
PSVA技术中的关键过程是对monomer的反应进行控制，包括反应速率，反应均匀性以及最终monomer的残留控制等等。只有对对上述情况进行很好的控制才能得到高品质的PSVA液晶面板。但是实际中要很好控制monomer在紫外光UV照射制程后的浓度仍然是一项重要课题。
发明内容
本发明的所要解决的技术问题在于，提供一种用于PSVA液晶显示器件的配向膜材料及相应的液晶面板，它能够使面板在UV照射制程后的monomer浓度控制在较低的水平，同时不显著增加面板内可以动离子的含量，由此避免面板在RA实验以及后续实际使用中出现由于monomer残留或离子浓度过高导致的品质下降问题。
为解决上述技术问题，本发明实施例提供一种配向膜材料，其用于聚合物稳定垂直配向液晶显示器，所述配向膜材料包括：高聚物、低聚物和溶剂，其中，所高聚物或/和低聚物中包含如下基团结构：
                                                
其中，X代表取代基团，在不同位置上的所述取代基团X相互独立，可以相同或不相同；m为每个苯环结构上取代基X的个数，所述各苯环上取代基个数m相互独立，可相同或不同；
其中，所述的高聚物为分子量大于10000的聚合物，所述的低聚物为分子量小于10000的聚合物；
所述溶剂包含以下溶剂中的一种或几种：
N-甲基吡咯烷酮溶剂、N-乙基吡咯烷酮溶剂以及丁内酯溶剂。
其中，所述溶剂重量占配向膜材料总重量的80%至99%。
其中，所述配向膜材料进一步包含流平剂和消泡剂。
相应地，本发明实施例的另一方面，提供一种液晶面板，所述液晶面板包含：
第一透明基板，具有第一配向膜；
第二透明基板，具有第二配向膜；以及
液晶组合物，填充于所述第一透明基板及第二透明基板之间，且所述液晶组合物接触所述第一配向膜及第二配向膜；
其中，所述配向膜的材料包括：高聚物、低聚物和溶剂，所高聚物或/和低聚物中包含如下基团结构：
 
其中，X代表取代基团，在不同位置上的所述取代基团X相互独立，可以相同或不相同；m为每个苯环结构上取代基X的个数，所述各苯环上取代基个数m相互独立，可相同或不同；
其中，所述的高聚物为分子量大于10000的聚合物，所述的低聚物为分子量小于10000的聚合物；
所述溶剂包含以下溶剂中的一种或几种：
N-甲基吡咯烷酮溶剂、N-乙基吡咯烷酮溶剂以及丁内酯溶剂。
其中，所述溶剂重量占配向膜材料总重量的80%至99%。
其中，所述配向膜材料进一步包含流平剂和消泡剂。
实施本发明实施例，具有如下的有益效果：
本发明实施例提供的配合膜材料，其至少包含一种聚合物，该聚合物的侧链上包含基团含有二苯甲酮的结构，由于二苯甲酮的结构对UV光非常敏感，能在较宽频谱范围内吸收UV光能量，分解形成自由基，引发monomer发生聚合反应，提高monomer的反应速率和转化效率。同时，该结构基团上连接有甲基丙烯酸酯基团，它本身可以发生聚合反应，所以由其产生的自由基或带电分子碎片能够参与聚合反应，连接到聚合物中，不会因此造成离子浓度过高的问题。
具体实施方式
下述结合附图，对本发明的具体实施方式进行说明。
如图1所示，示出了本发明的一种聚合物稳定垂直配向液晶显示面板的示意图，该液晶显示面板用于PSVA LCD，其包括：
第一透明基板1，具有第一配向膜50；
第二透明基板2、具有第二配向膜51；
液晶组合物3，填充于所述第一透明基板1及第二透明基板2之间，且所述液晶组合物3接触所述第一配向膜50及第二配向膜51，液晶组合物中至少包含有液晶分子30，以及可聚合单体，在第一配向膜50和第二配向膜51的作用下，该可聚合单体会在靠近第一基板1及第二基板2处形成Bump（隆起物）31；以及
将液晶封于两基板内的边框胶材4；
其中，所述第一配向膜和第二配向膜所采用的材料包括：
高聚物、低聚物和溶剂，其中，所高聚物或/和低聚物中包含如下基团结构：
 
其中，该基团结构包括二苯甲酮的结构，且连接有甲基丙烯酸酯基团；X代表取代基团，在不同位置上的所述取代基团X相互独立，可以相同或不相同；m为每个苯环结构上取代基X的个数，所述各苯环上取代基个数m相互独立，可相同或不同。
其中，溶剂包含以下溶剂中的一种或几种：
N-甲基吡咯烷酮溶剂（NMP）、N-乙基吡咯烷酮溶剂（NEP）以及丁内酯（Gamma-BL）溶剂，且所述溶剂重量占配向膜材料总重量的80%至99%。所述的高聚物为分子量大于10000的聚合物，所述的低聚物为分子量小于10000的聚合物。
另外所述配向膜材料进一步包含流平剂和消泡剂。
本发明实施例提供的配合膜材料，其至少包含一种聚合物，该聚合物的侧链上包含基团含有二苯甲酮的结构，由于二苯甲酮的结构对紫外光非常敏感，能在较宽频谱范围内吸收紫外光能量，分解形成自由基，引发可聚合单体发生聚合反应，提高可聚合单体的反应速率和转化效率。同时，该结构基团上连接有甲基丙烯酸酯基团，它本身可以发生聚合反应，所以由其产生的自由基或带电分子碎片能够参与聚合反应，连接到聚合物中，不会因此造成离子浓度过高的问题。
本发明实话例通过采用配向膜材料来调控PSVA液晶混合物中可聚合单体的反应速率与可聚合单体残留量，控制液晶面板中的可移动离子含量，以此提高液晶面板的品质可靠性。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此等同变化，仍属本发明所涵盖的范围。
