Description

液晶配向方法和液晶配向系统 技术领域
本发明涉及显示技术领域，特别是涉及一种液晶配向方法和液晶配向系统。。
 背景技术
液晶显示面板的通常是由彩膜基板(Color Filter Substrate, CF Substrate)、薄膜晶体管阵列基板(Thin-Film Transistor Array Substrate，TFT Array Substrate)以及配置于两基板间的液晶层(Liquid Crystal Layer)构成。液晶显示面板的工作原理是通过在两片玻璃基板上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。
按照液晶的取向方式不同，液晶显示面板可以分为垂直配向(Vertical Alignment，VA)型、扭曲向列(Twisted Nematic，TN)或超扭曲向列(Super Twisted Nematic，STN)型、平面转换(In-Plane Switching，IPS)型、及边缘场开关(Fringe Field Switching，FFS)型等。现有的液晶显示面板光配向时，先在液晶盒两端的氧化铟锡电极上施加电压，待液晶排列规整后，对液晶盒照射UV光，液晶中的感光单体发生分离聚合到PI（Polyimide，聚酰亚胺）表面，固定PI表面的液晶分子取向，待电压去掉后，PI表面的液晶分子形成预倾角，提升液晶盒中液晶的响应速度。使用该种方式进行光配向时，需要在阵列基板上增加大量走线，以给CF基板侧的氧化铟锡提供电压，从而导致阵列基板的利用率下降。

 有益效果
相较于现有的液晶配向方法和液晶配向系统，本发明的液晶配向方法和液晶配向系统，通过在第一基板上设置电极板来对液晶层配向，减少了液晶显示面板中走线的数量。
为让本发明的上述内容能更明显易懂，下文特举优选实施例，并配合所附图式，作详细说明如下：

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
请参照图1，图1为本发明实施例提供的液晶配向方法的流程示意图。该液晶配向方法包括：
S101，提供第一基板，在第一基板上形成第一电极层和覆盖第一电极层的第一配向膜。
在一些实施例中，该第一基板为彩膜基板。该第一电极层为公共电极层。可以在第一电极层上涂布聚酰亚胺溶液，聚酰亚胺溶液依靠自身表面张力得到平整、厚度均匀的膜，再经过高温缩合得到第一配向膜，即第一配向膜的组成材料包括聚酰亚胺。
S102，提供与第一基板相对设置的第二基板，在第二基板上形成第二电极层和覆盖第二电极层的第二配向膜。
在一些实施例中，该第二基板为阵列基板。该第二电极层为像素电极层。可以在第二电极层上涂布聚酰亚胺溶液，聚酰亚胺溶液依靠自身表面张力得到平整、厚度均匀的膜，再经过高温缩合得到第二配向膜，即第二配向膜的组成材料包括聚酰亚胺。
S103，在第一配向膜和第二配向膜之间形成液晶层。
具体的，可以在第一配向膜和第二配向膜之间注入含有反应单体的液晶分子，以形成该液晶层，即液晶层包括反应单体和液晶分子。
S104，提供电极板，并将电极板设置在第一基板远离第一电极层的一侧上。
电极板包括玻璃基板和电极层。在一些实施例中，该电极层为透明导电膜。该电极层的组成材料包括氧化铟锡。
S105，在电极板和第二电极层之间施加驱动电压，对液晶层配向。
请参照图2，图2为本发明实施例提供的液晶配向方法对应的电路的结构示意图。该电路不仅具有液晶电容C lc和存储电容Cst，还具有耦合电容Cgl。具体的，当电极板和第二电极层之间施加了驱动电压时，电极板和第二电极层之间形成耦合电容Cgl，即液晶层两端的电压通过该耦合电容Cgl产生。这样不需要在第二基板上设置大量走线即可给液晶层提供电压，也提高了第二基板的利用率。
具体的，如图3所示，在电极板和第二电极层之间施加驱动电压Voltage，使反应单体和液晶分子以预倾角排列，然后继续施加驱动电压Voltage，并利用紫外光UV light照射电极板，以使反应单体产生聚合反应沉积于第一配向膜和第二配向膜的表面，将液晶分子以预倾角固定。
在一些实施例中，对液晶层配向步骤之后还包括将电极板从第一基板上剥离,可以避免对通过上述方法进行液晶配向的液晶显示面板的厚度造成影响。
本发明实施例中还提供了一种液晶配向系统，如图4所示，液晶配向系统1包括液晶显示面板1000、电源2000以及与所述液晶显示面板1000独立的电极板3000。
液晶显示面板1000包括第一基板100、第二基板200和液晶层300。第一基板100包括第一电极层101和覆盖第一电极层101的第一配向膜102。第二基板200与第一基板100相对设置，第二基板200包括第二电极层201和覆盖第二电极层201的第二配向膜202。液晶层300设置在第一配向膜102和第二配向膜202之间。在一些实施例中，第一配向膜102和第二配向膜202的组成材料包括聚酰亚胺。
电极板3000设置在第一基板100远离第一电极层101的一侧上。在一些实施例中，电极板3000包括玻璃基板3001和电极层3002，电极层3002设置在玻璃基板3001和第一电极层101之间。在一些实施例中，电极层402的组成材料包括氧化铟锡。
电源2000连接电极板3000和第二电极层201，所述电源2000用于向电极板3000和第二电极层201施加驱动电压，以对液晶层300配向。具体的，电源2000连接电极层3002和第二电极层201，所述电源用于向电极层3002和第二电极层201施加驱动电压。
在一些实施例中，如图5所示，该液晶配向系统1还包括光源4000。光源4000用于向电极板3000发射紫外光，以使液晶层300中的反应单体产生聚合反应沉积于第一配向膜102和第二配向膜202的表面，将液晶层300中的液晶分子以预倾角固定。
在一些实施例中，该液晶配向系统1还包括剥离装置，比如夹子等，用于将电极板3000从第一基板100上剥离。
具体的，如图3所示，液晶配向系统1对该液晶显示面板1000配向过程如下：通过电源2000在电极层402和第二电极层201之间施加驱动电压Voltage，使液晶层300中的反应单体和液晶分子以预倾角排列，然后继续通过电源2000施加驱动电压Voltage，并利用光源4000向电极板400发射紫外光UV light，以使反应单体产生聚合反应沉积于第一配向膜102和第二配向膜202的表面，将液晶分子以预倾角固定。
本发明实施例的液晶配向方法和液晶配向系统，通过在第一基板上设置电极板来对液晶层配向，减少了液晶显示面板中走线的数量。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
