具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
同时，在以下说明中，出于解释的目的而阐述了许多具体细节，以提供对本发明实施例的彻底理解。然而，对本领域的技术人员来说显而易见的是，本发明可以不用这里的具体细节或者所描述的特定方式来实施。
随着显示技术的发展，曲面液晶显示装置开始出现在人们的视野中。曲面液晶显示装置因具有较好的视觉体验效果而被越来越多的消费者所喜爱。目前，在制造曲面液晶显示装置的过程中，通常是先将液晶显示面板做成平面结构，然后再对平面结构的液晶显示面板进行弯曲处理，从而得到曲面液晶显示面板。
图1和图2分别示出了现有的液晶显示面板中阵列基板的部分结构示意图以及对应的剖视图。
从图1和图2中可以看出，现有的阵列基板包括：基板101、钝化层102、数据线103、色阻层104以及像素电极层105。其中，钝化层102形成在基板101上，数据线103形成在钝化层102上。色阻层104形成在钝化层102和数据线103上。图2示出了两个子像素单元，对应地，色阻层104包括第一色阻单元104a和第二色阻单元104b。其中，第一色阻单元104a和第二色阻单元104b的交界面处于数据线103正上方。
相应地，像素电极层105包括第一像素电极105a和第二像素电极105b。这两个像素电极均包括：第一主干电极、第二主干电极和多个枝干电极。其中，这两个像素电极的主干电极相对设置。
在对液晶显示面板进行弯曲的过程中，由于液晶显示面板中的阵列基板是以面板中心为基准的，因此阵列基板在水平方向上会沿左右两边逐渐产生相对位移，进而引起阵列基板的像素电极的第一主干电极(即与数据线103平行的电极)产生相对位移，从而使得电场发生变化，造成曲面液晶显示装置的子像素电极中主干电极附近的位置产生暗纹甚至暗团。
针对现有阵列基板所存在的上述问题，本实施例提供了一种新的阵列基板。该阵列基板包括多条数据线和多条扫面线，由这些数据线和扫描线交错形成了多个子像素单元。其中，相邻的两个子像素单元会形成一个像素模块。图3和图4分别示出了该阵列基板中两个相邻像素模块的结构示意图以及其中一个像素模块的剖视图。
如图3和图4所示，本实施例中，像素模块包括：基板301、钝化层302、数据线303、色阻层304、像素电极层305以及凸起部306。钝化层302形成在基板301上，数据线303形成在钝化层302上。色阻层304形成在钝化层302和数据线303上。本实施例中，基板301优选地采用玻璃基板。当然，在本发明的其他实施例中，基板301还可以采用其他合理的材料(例如透光树脂等)来实现，本发明不限于此。
色阻层304包括第一色阻单元304a和第二色阻单元304b。其中，第一色阻单元304a和第二色阻单元304b分别对应于两个不同的子像素单元。本实施例中，这两个色阻单元具有不同的颜色。例如，当第一色阻单元304a为红色色阻时，第二色阻单元304b为绿色色阻或蓝色色阻。
如图4所示，第一色阻单元304a与第二色阻单元304b的色阻交界面处于数据线303的正上方。本实施例中，第一色阻单元304a与第二色阻单元304b的色阻交界面并非是垂直于数据线303的，而是与数据线303呈一定的倾角。这样，第一色阻单元304a与第二色阻单元304b便在数据线303的上方存在部分重叠。
需要说明的是，在本发明的其他实施例中，第一色阻单元304a与第二色阻单元304b的色阻交界面与数据线303的倾角可以根据不同的需要采用不同的倾角大小，其既可以为如图4所示的锐角，也可以为钝角，抑或是直角，本发明不限于此。
像素电极层305形成在色阻层304上，像素电极层305包括对应于不同子像素单元的像素电极。本实施例中，各个子像素单元中的像素电极均为柔性电极，这些像素电极能够有效地应用在曲面液晶显示面板中。如图3所示，本实施例中，各个子像素单元的像素电极的结构相同，因此为了描述的方便，以下以对应于第一子像素单元的第一像素电极为例来对本实施例所提供的阵列基板的结构作进一步的说明。
如图3所示，本实施例中，第一像素电极包括：第一主干电极307、第二主干电极308和多个枝干电极309。其中，第一主干电极307平行且靠近于第一子像素单元的第一边(即处于数据线303上方的边)。第二主干电极308与第一主干电极307垂直，其一端优选地与第一主干电极307的中点位置相连接从而形成T形结构。
各个枝干电极309的一端至少与第一主干电极307和第二主干电极308之一连接。第一主干电极307和第二主干电极308将第一子像素单元划分为了两个显示区域。这些枝干 电极309分别位于这两个显示区域中。其中，优选地，处于同一显示区域中的枝干电极309采用平行等间距的排布方式。当然，在本发明的其他实施例中，处于同一显示区域中的枝干电极309也可以采用其他合理的排布方式(例如平行不等间距排布或非平行排布等)，本发明同样不限于此。
在同一像素模块中，对应于两个子像素单元的像素电极优选地关于数据线303的中心垂面相对称，即第一像素电极与第二像素电极是关于数据线303的中心垂面相对称的。
需要说明的是，在本发明的其他实施例中，第一像素电极与第二像素电极也可以采用非对称的排布方式，本发明不限于此。
凸起部306形成在第一像素电极与第二像素电极之间并且位于第一色阻单元304a和第二色阻单元304b的色阻交界面的正上方(也是数据线303的正上方)。这样，第一像素电极与第二像素电极也是关于凸起部306对称的。本实施例中，凸起部306优选地覆盖部分第一像素电极和第二像素电极。
当然，在本发明其他实施例中，如图5所示，凸起部306还可以不覆盖第一像素电极和/或第二像素电极，本发明不限于此。
本实施例中，凸起部306的颜色与第一色阻单元和第二色阻单元的颜色是不同的。即，当第一色阻单元和第二色阻单元的颜色分别为红色和绿色时，凸起部306的颜色则为蓝色；当第一色阻单元和第二色阻单元的颜色分别为红色和蓝色时，凸起部306的颜色则为绿色；依此类推。
从图3中可以看出，由于暗纹或暗团主要是由于相邻的两个第一主干电极产生相对位移而使得电场发生变化所产生的，因此本实施例中，凸起部306优选地只存在于各个像素模块的两个子像素单元之间，两个相邻的像素模块之间并不配置凸起部306。当然，在本发明的其他实施例中，根据实际需要，相邻的两个像素模块之间也可以配置凸起部306，本发明不限于此。
由于凸起部306的高度高于第一像素电极和第二像素电极的高度，因此在使用时，液晶显示面板中靠近凸起部306的液晶将会沿着凸起部306向两侧倾倒，从而使得液晶达到了更好的配向效果，这样也就改善甚至消除了现有的阵列基板在显示时所出现的暗纹或暗团，提高了视觉体验效果。
本实施例还提供了一种采用如上所述的阵列基板的液晶显示面板。
从上述描述中可以看出，本实施例所通过的阵列基板通过设置凸起部来以武力方式来稳定凸起部周围的液晶的倾角，从而改善甚至消除现有的阵列基板在显示时所出现的 暗纹或暗团，提高了视觉体验效果。
应该理解的是，本发明所公开的实施例不限于这里所公开的特定结构或材料，而应当延伸到相关领域的普通技术人员所理解的这些特征的等同替代。还应当理解的是，在此使用的术语仅用于描述特定实施例的目的，而并不意味着限制。
说明书中提到的“一个实施例”或“实施例”意指结合实施例描述的特定特征、结构或特性包括在本发明的至少一个实施例中。因此，说明书通篇各个地方出现的短语“一个实施例”或“实施例”并不一定均指同一个实施例。
虽然上述示例用于说明本发明在一个或多个应用中的原理，但对于本领域的技术人员来说，在不背离本发明的原理和思想的情况下，明显可以在形式上、用法及实施的细节上作各种修改而不用付出创造性劳动。因此，本发明由所附的权利要求书来限定。
