具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。需要注意的是，附图中各图形的尺寸和形状不反映真实比例，目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“内”、“外”、“上”、“下”等仅用于表 示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
随着显示技术的发展，高端显示产品对显示器的各项性能均提出了更高的要求。VA模式具有高的正视角对比度，但在不同视角下的对比度不均匀；而ADS具有更优秀的宽视角特性(即背光透过的亮度不随视角的变化而发生变化)，为结合二者的优势，一种利用边缘电场驱动垂直取向的液晶模式被提出来。在该模式下，电极结构与ADS相同，即像素电极和公共电极位于同一基板的上下两层，其中，一层电极设计为条状，另一层电极设计为面状。液晶及其初始取向与VA模式相同，即采用垂直取向的负性液晶或正性液晶。当液晶不被驱动(暗态L0)时，该模式具有与VA同等的L0水平，而当液晶被驱动时，又能兼具ADS的宽视角及色彩优势，而且在像素结构上要比VA简单。
当电场非零时，液晶被驱动，此时条状电极之间的有效电场包括垂直分量Ez和垂直条状电极延伸方向的分量Ey，如图1所示。其中垂直分量Ez使液晶由垂直方向向水平方向(xy平面)偏转，垂直条状电极延伸方向的分量Ey使液晶旋转至xy平面内平行于条状电极的方向，以完成液晶分子的旋转。然而为实现多个条状电极的连接，一般在多个条状电极的周围设置连接电极，在此情况下，条状电极的边缘区域除了条状电极与面状电极之间的有效电场外，增加了连接电极和面状电极之间的电场，而且该电场具有沿x方向的分量Ex，如图2所示。可见，由于电极的方向不同，使得边缘区域的电场分布比较复杂，导致液晶分子难以偏转而出现黑色向错线。
针对相关技术中存在的上述技术问题，本公开实施例提供了一种阵列基板，如图3至图6所示，包括：
衬底基板01；
沿第一方向延伸的多条栅线02，位于衬底基板01之上；
多条数据线03，沿与第一方向交叉的第二方向延伸；
多个像素单元，位于由多条栅线02和多条数据线03限定出的区域；像素单元具有在第二方向上延伸且在第一方向上相对的第一侧和第二侧；
像素单元包括第一电极04，其中：
第一电极04包括多个条状电极401，至少部分条状电极401的具有延伸方向不同的第一部P1和第二部P2，第一部P1在第一侧相互连接，第二部P2在第二侧相互断开，且第一部P1和第二部P2的长度不同。
在本公开实施例提供的上述阵列基板中，通过设置至少部分条状电极401的第二部P2在第二侧相互断开，使得临近第二侧的第二部P2(相当于条状电极401的边缘部)与面状电极之间的Ex电场分量减小，优化了电场分布，如图7所示。因此，条状电极401整体上与面状电极之间的电场可视为仅包括Ez和Ey两个有效分量，基于此，第一电极04可控制位于其中间区域和边缘区域对应的液晶分子旋转程度相近，从而有效避免了黑色相错线的出现，提高了显示效果。
测试结果表明，相较于条状电极401未断开的相关技术，本公开通过设置第二部P2在第二侧相互断开，可以使相错线所在黑区向有效显示区(AA)外移动4.9μm，如图8所示，从而有效改善了显示质量。另一方面，相关技术的灰阶响应时间为29.9ms，本公开的灰阶响应时间为23.2ms，可见，断开第二部P2可以加快响应速度，这是因为断开后避免了向错线的出现、移动及稳定过程。
可选地，在本公开实施例提供的上述阵列基板中，为保证光线透过率，条状电极401的线宽可以大于或等于1.9μm且小于或等于3.3μm，条状电极401之间的距离可以大于或等于2.3μm且小于或等于4.8μm，条状电极401的延伸方向与偏光片光轴之间的夹角可以大于或等于35°且小于或等于55°，例如45°。需要说明的是，在条状电极401包括延伸方向不同的第一部P1和第二部P2时，条状电极401的延伸方向具体是指长度较大的那部分的延伸方向。例如第一部P1的长度大于第二部P2的长度，则条状电极401的延伸方向即是第一部P1的延伸方向，以下以条状电极401的延伸方向是第一部P1的延伸方向为例进行说明。
可选地，在本公开实施例提供的上述阵列基板中，为有效增加Ey电场分 量，减少Ex电场分量，可以设置第一部P1的延伸方向与第二部P2的延伸方向之间的夹角大于0°且小于或等于45°。较佳地，第一部P1的延伸方向与第二部P2的延伸方向之间的夹角大于或等于10°且小于或等于15°。具体可以为10°、11°、12°、13°、14°、15°等。
可选地，在本公开实施例提供的上述阵列基板中，第二部P2的长度小于第一部P1的长度，其中第二部P2的长度具体可根据像素边缘区域进行设计调整。示例性地，如图6所示，第二部P2在其延伸方向上的长度L可以设计为大于或等于1μm且小于或等于3μm，具体可以为1μm、1.5μm、2μm、2.5μm、3μm等。可选地，第二部P2为直线型时，第二部P2的延伸方向为直线走向；第二部P2为折线型时，第二部P2的延伸方向为折线走向；第二部P2为曲线型时，第二部P2的延伸方向为弧线走向。
可选地，在本公开实施例提供的上述阵列基板中，第一部P1和第二部P2可以为直线型、折线型、曲线型等结构，例如图5和图6所示，第一部P1为直线型，第二部P2为偏离第一部P1的延伸方向弯曲的曲线型。并且由图5和图6可见，第一部P1具体为延伸方向与条状电极401的整体延伸方向相同的部分，第二部P2具体为延伸方向与条状电极401的整体延伸方向不同的部分。
相关技术中，在边缘区域的液晶不动区域和中间区域的液晶旋转区域之间会产生过渡区，在不同的电压下，液晶旋转与不旋转之间的平衡情况不同，从而导致黑色向错线的位置不固定。通过设置第二部P2偏离第一部P1的延伸方向弯曲，进一步增加了Ey电场分量，减少了有害电场分量Ex，从而可固定甚至消除相错线。
可选地，在本公开实施例提供的上述阵列基板中，如图5所示，部分或全部第二部P2的弧度相同，以便于工艺制作。
可选地，在本公开实施例提供的上述阵列基板中，为利于制作，可设置第一部P1的线宽与第二部P2的线宽相同，例如大于或等于1.9μm且小于或等于3.3μm。需要说明的是，在具体制作过程中，受刻蚀等因素的影响，第二 部P2的线宽会随其与第一部P1之间距离的增加而略有缩减。另外，第二部P2远离第一部P1的一端可能是直角、锐角、钝角、圆角，一般受刻蚀等工艺因素的影响，第二部P2相对于第一部P1的最远端为圆角，如图6所示。
可选地，在本公开实施例提供的上述阵列基板中，第一电极04可以为单畴结构、双畴结构、四畴结构等。
例如图5、图6、图9和图10所示，第一电极04为单畴结构，具体地第一电极04所包括的多个条状电极401沿第三方向延伸，并沿与第三方向交叉的第四方向排列；具体地，第三方向与偏光片光轴之间夹角的范围大于或等于35°且小于或等于55°，优选45°；
第一电极04还包括连接电极402，该连接电极402包括：在第一方向上延伸，并沿第二方向排列的第一连接电极4021和第二连接电极4022，以及在第一侧且与第一连接电极4021和第二连接电极4022连接的第三连接电极4023；
第一部P1与第一连接电极4021或第三连接电极4023连接，在第一方向上的正投影长度小于第一侧与第二侧之间的距离且与第二侧互不交叠的条状电极401，连接于第二连接电极4022和第三连接电极4023之间。
再如图11至图18所示，第一电极04为双畴结构，多个条状电极401包括：多个第一条状电极4011和多个第二条状电极4012；其中多个第一条状电极4011的延伸方向与多个第二条状电极4012的延伸方向不同，可选的，多个第一条状电极4011与多个第二条状电极4012关于第一方向对称。在图11至图16中，多个第一条状电极与多个第二条状电极之间的夹角大于或等于80°且小于或等于100°，优选90°；在图17和图18中，多个第一条状电极与多个第二条状电极之间的夹角大于0°且小于或等于10°。具体可根据上下偏光片的透光轴方向决定。
需要说明的是，由于具有第二部P2的第一条状电极4011与具有第二部P2的第二条状电极4012是对称设置的，可选的，第一条状电极4011中第二部P2形状与第二条状电极4012中第二部P2形状也是对称的。具体的，与图 12所示第二条状电极4012中第二部P2形状对称的第一条状电极4011中第二部P2形状可参见图6；与图14所示第二条状电极4012中第二部P2形状对称的第一条状电极4011中第二部P2形状可参见图10。另外，在图15和图17中，相互对称的第一条状电极4011与第二条状电极4012所含第二部P2设置方式与图11大致相同，在图16和图18中，相互对称的第一条状电极4011与第二条状电极4012所含第二部P2设置方式与图13大致相同。
具体地，在图11和图15中，第二部P2均向远离多个第一条状电极4011与多个第二条状电极4012的对称轴的一侧弯折。在图13和图16中，第二部P2均向靠近多个第一条状电极4011与多个第二条状电极4012的对称轴的一侧弯折。其中，第二部P2均向远离多个第一条状电极4011与多个第二条状电极4012的对称轴的一侧弯折比均向靠近该对称轴弯折更有效。具体而言，由于第二部P2向靠近多个第一条状电极4011与多个第二条状电极4012的对称轴弯折，导致相邻两个条状电极401之间的距离缩短(即一个第二部P2与相邻第一部P1之间的距离)；而与向靠近多个第一条状电极4011与多个第二条状电极4012的对称轴弯折相比，当第二部P2向远离多个第一条状电极4011与多个第二条状电极4012的对称轴弯折时不会引起相邻条状电极401之间的距离增加，可以更多地增加有效电场的Ey分量，从而可以避免不必要的有害电场的影响，更利于边缘区域对应的液晶保持与中间区域对应液晶具有一致的偏转方向。测试结果表明，第二部P2向靠近多个第一条状电极4011与多个第二条状电极4012的对称轴弯折的灰阶响应时间为19ms，第二部P2向远离多个第一条状电极4011与多个第二条状电极4012的对称轴弯折的灰阶响应时间为17ms。
另外，在如图11和图13中，条状电极401自靠近第一侧的一端至靠近第二侧的一端与对称轴的距离逐渐减小，使得第一条状电极4011与第二条状电极4012之间形成类似“>”的结构。此时，为实现各条状电极401的连接，如图11和图13所示，第一电极04还包括连接电极402，该连接电极402包括：在第一方向上延伸且在第二方向上排列的第一连接电极4021和第二连接 电极4022，以及在第一侧与第一连接电极4021和第二连接电极4022连接的第三连接电极4023；其中，
在第一方向上的正投影长度小于第一侧与第二侧之间的距离且与第二侧互不交叠的第一条状电极4011和第二条状电极4012中，关于第三连接电极402的中垂线对称的第一条状电极4011的一端与第二条状电极4012的一端连接，另一端与第三连接电极4022连接；
第一条状电极4011所含的第一部P1与第一连接电极4021或第三连接电极4023连接，第二条状电极4012所含的第一部P1与第二连接电极4022或第三连接电极4023连接。
在图15和图16中，条状电极401自靠近第一侧的一端至靠近第二侧的一端与对称轴的距离逐渐增大，使得第一条状电极4011与第二条状电极4012之间形成类似“<”的结构。此时，为了实现各条状电极401的连接，如图15和图16所示，第一电极04还包括连接电极402，该连接电极包括：在第一方向上延伸且在第二方向上排列的第一连接电极4021、第四连接电极4024和第二连接电极4022，以及在第一侧与第一连接电极4021、第四连接电极4024和第二连接电极4022连接的第三连接电极4023；其中，
在第一方向上的正投影长度小于第一侧与第二侧之间的距离且与第二侧互不交叠的第一条状电极4011和第二条状电极4012中，第一条状电极4011连接于第一连接电极4021与第三连接电极4023之间，第二条状电极4012连接于第二连接电极4022与第三连接电极4023之间；
第一条状电极4011所含的第一部P1与第三连接电极4023或第四连接电极4024连接；第二条状电极4012所含的第一部P1与第三连接电极4023或第四连接电极4024连接。
在图17和图18中，由于条状电极401的倾斜角度较小，故全部条状电极401的第一端在第一侧均可通过第三连接电极4023连接。
可选地，在本公开实施例提供的上述阵列基板中，如图3和图4所示，一般还包括：位于第一电极04与衬底基板01之间的第二电极05，第二电极 05为面状电极，以及位于第一电极04与第二电极05之间的绝缘层06。在另一些实施例中，第二电极05还可以位于第一电极04背离衬底基板01的一侧。具体地，第一电极04可以为像素电极(Pix)，第二电极05为公共电极(Com)；或者第一电极04可以为公共电极，第二电极05为像素电极，在此不做限定。在本公开中以第一电极04为像素电极，第二电极05为公共电极为例进行说明。
可选地，在本公开实施例提供的上述阵列基板中，如图3所示，第一电极04为像素电极，第二电极05为公共电极，由于电场对液晶的排列有很大影响，因此，此处对公共电极(例如第二电极05)的大小进行优化。设定像素电极(例如第一电极04)的边界与左右两侧数据线03的距离d1相等，公共电极(例如第二电极05)的边界与左右两侧数据线03的距离d2相等，如图19所示，以公共电极(例如第二电极05)和像素电极(例如第一电极04)相对于数据线03距离相等(即公共电极的边界至数据线03的距离与像素电极至数据线03的距离之差△d＝0)为基准，当公共电极(例如第二电极05)向数据线03方向扩大0.5μm(即△d＝0.5)、缩小0.5μm(即△d＝-0.5)以及缩小1.0μm(即△d＝-1)三种情况下，相错线所在黑区位置分别为：远离有效显示区0.22μm、缩进有效显示区0.4μm、缩进有效显示区1.0μm，如图20所示。因此，为防止黑区进入有效显示区影响显示效果，在本公开实施例提供的上述阵列基板中，如图1所示，可以设置像素电极(例如第一电极04)在衬底基板01上的正投影位于公共电极(例如第二电极05)的正投影内。具体地，公共电极(例如第二电极05)在衬底基板01上的正投影边界与相邻数据线03的正投影之间的距离，小于像素电极(例如第一电极04)在衬底基板01上的正投影边界与相邻数据线03的正投影之间的距离。在一些实施例中，即公共电极的边界至数据线03的距离与像素电极至数据线03的距离之差△d可以大于或等于0.5μm且小于或等于2.5μm，例如0.5μm、1μm、1.5μm、2μm、2.5μm等。
可选地，在本公开实施例提供的上述阵列基板中，如图21所示，还包括： 位于多个像素单元所在层背离衬底基板01一侧的第一取向层07，第一取向层07的取向方向由第一侧指向第二侧，也就是说，在本公开中第一取向层07的取向(rubbing)方向近似为0°(从左向右)，从条状电极401没有断开的一侧指向断开的一侧，这样可以使得液晶的预倾角约为90°±5°，可选的，液晶的预倾角约为90°，液晶的方位角约为0°±45°，可选的，液晶的方位角约为0°。另外由于rubbing末端位置(即第二侧)的黑色相错线更严重，因此去掉相关技术中连接电极402在该侧的部分，可有效改善黑色相错线。
一般地，在本公开实施例提供的上述阵列基板中，如图3所示，还可以包括：与像素电极(例如第一电极04)连接的晶体管08；具体地，晶体管08设置在像素单元的间隙处，示例性地，晶体管08设置在第一侧的像素单元间隙处。
基于同一发明构思，本公开实施例提供了一种液晶显示面板，由于该液晶显示面板解决问题的原理与上述阵列基板解决问题的原理相似，因此，本公开实施例提供的该液晶显示面板的实施可以参见本公开实施例提供的上述阵列基板的实施，重复之处不再赘述。
具体地，本公开实施例还提供了一种液晶显示面板，如图21所示，包括：
相对而置的阵列基板和彩膜基板，阵列基板为上述阵列基板；
液晶层09，位于阵列基板与彩膜基板之间；其中液晶层09可以为正性液晶，也可以为负性液晶。
可选地，在本公开实施例提供的上述液晶显示面板中，如图21所示，彩膜基板包括黑矩阵10，或者阵列基板包括位于像素电极(例如第一电极04)面向液晶层09一侧的黑矩阵10；
第二部P2在液晶显示面板所在层上的至少部分正投影位于黑矩阵10的正投影内。
断开的第二部P2位于黑矩阵10下方，可以有效减少黑区在有效显示区域的出现，进一步提高了显示效果。
具体地，黑矩阵10的宽度设计可以根据需要选择。考虑金属材质的数据 线03遮蔽以及串扰等影响，在本公开实施例提供的上述液晶显示面板中，黑矩阵10的设计最小值可以采用宽度为d BM＝d cell+2*d 对位，其中，d cell为液晶显示面板的盒厚，d 对位为液晶显示面板的对位精度。例如，3.5μm的盒厚设计，工艺中的设备对位精度为3μm，则黑矩阵10的宽度可以采用3.5μm+2*3μm＝9.5μm，黑矩阵10的中心线位置与数据线03的中心线位置一致。而考虑对第二侧的相错线的遮蔽效果，可以适当增加黑矩阵10的宽度，例如，将第二侧的黑矩阵10覆盖至从第二部P2的最远端(即第二部P2的圆角端)向内延伸1μm～3μm(即可以延伸至完全覆盖第二部P2)。
需要说明的是，在本公开实施例提供的上述液晶显示面板中，如图21所示，一般地阵列基板还包括：下偏光片11；彩膜基板还包括第二取向层12、玻璃基底13和上偏光片14。在一些实施例中，还可将像素电极设置在阵列基板上，公共电极设置在彩膜基板上，在此不做限定。对于液晶显示面板的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。
另一方面，本公开实施例还提供了一种液晶显示装置，如图22所示，包括本公开实施例提供的上述液晶显示面板，以及位于液晶显示面板入光侧的背光模组15。具体地，该背光模组15可以为直下式背光模组，也可以为侧入式背光模组。该液晶显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、智能手表、健身腕带、个人数字助理等任何具有显示功能的产品或部件。对于液晶显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。另外，由于该液晶显示装置解决问题的原理与上述液晶显示面板解决问题的原理相似，因此，该液晶显示装置的实施可以参见上述液晶显示面板的实施例，重复之处不再赘述。
本公开实施例提供的上述阵列基板、液晶显示面板及液晶显示装置，包括：衬底基板；沿第一方向延伸的多条栅线，位于衬底基板之上；多条数据线，沿与第一方向交叉的第二方向延伸；多个像素单元，位于由多条栅线和 多条数据线限定出的区域；像素单元具有在第二方向上延伸且在第一方向上相对的第一侧和第二侧；像素单元包括第一电极，其中：第一电极包括多个条状电极，至少部分条状电极的具有延伸方向不同的第一部和第二部，第一部在第一侧相互连接，第二部在第二侧相互断开，且第一部和第二部的长度不同。通过设置至少部分条状电极的第二部在第二侧相互断开，使得临近第二侧的第二部(相当于条状电极的边缘部)与公共电极之间的Ex电场分量减小，因此，条状电极整体上与公共电极之间的电场可视为仅包括Ez和Ey两个分量，基于此，第一电极可控制位于其中间区域和边缘区域对应的液晶分子旋转程度相近，从而有效避免了黑色相错线的出现，提高了显示效果。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开实施例的精神和范围。这样，倘若本公开实施例的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
