Description

液晶显示面板及显示器 技术领域
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示面板。
背景技术
根据驱动液晶的电场方向，液晶显示装置分为垂直电场型液晶显示装置和水平电场型液晶显示装置。垂直电场型液晶显示装置主要包括扭曲向列(TN)模式和垂直取向(VA)模式，水平电场型液晶显示装置主要包括共平面切换(IPS)模式、边界电场切换(FFS)模式和高级超维场开关(ADS)模式。相对于垂直电场型液晶显示装置，水平电场型液晶显示装置不需要额外的光学补偿膜，即能实现宽视角。但是，对于水平电场型液晶显示装置，其液晶层中的电场分布不均匀，存在电场未覆盖的局部区域，该局部区域不能透光，从而导致液晶面板的整体透过率不高。
因此，针对上述技术问题，有必要提供一种液晶显示面板及显示器。
发明内容
为克服现有技术的不足，本发明的目的在于提供一种液晶显示面板及显示器。
为了实现上述目的，本发明实施例提供的技术方案如下：
一种液晶显示面板，所述显示面板包括相对设置的第一基板和第二基板、以及位于第一基板和第二基板之间的液晶层，所述第一基板上在朝向第二基板 一侧依次设有第一公共电极和绝缘层，所述绝缘层上设置有若干第一像素电极，所述第二基板在朝向第一基板一侧设有若干第二公共电极和第二像素电极，所述第二公共电极和第二像素电极为间隔排列设置。
作为本发明的进一步改进，所述第一基板为阵列基板，第二基板为彩膜基板。
作为本发明的进一步改进，所述第一像素电极在绝缘层上等间距阵列排布，第一公共电极与第一像素电极之间形成有若干水平电场。
作为本发明的进一步改进，所述第二公共电极在第二基板上等间距阵列排布。
作为本发明的进一步改进，相邻所述第二公共电极之间的间距与相邻第一像素电极之间的间距相等，且所述第二公共电极和第一像素电极在垂直位置上交叉分布。
作为本发明的进一步改进，所述第二像素电极在第二基板上等间距阵列排布。
作为本发明的进一步改进，相邻所述第二像素电极之间的间距与相邻第一像素电极之间的间距相等，且所述第二像素电极和第一像素电极在垂直位置上交叉分布。
作为本发明的进一步改进，相邻所述第二像素电极和第二公共电极之间的间距为相邻第一像素电极间距的一半，相邻第二像素电极和第二公共电极沿第一像素电极所在的轴线或相邻第一像素电极的中轴线对称分布。
相应地，一种液晶显示器，所述液晶显示器包括上述液晶显示面板。
本发明在第二基板上增加了第二像素电极和第二公共电极，第二像素电极和第二公共电极相间排列且在第二像素电极和第二公共电极之间形成水平电 场，可以使暗纹位置处倾斜的液晶分子趋于水平方向排列，从而提高暗纹位置处光的穿透率，使液晶面板和显示器中的暗纹消失。
附图说明
图1为现有技术的液晶显示面板的结构示意图。
图2为本发明实施例1中液晶显示面板的结构示意图。
图3为本发明实施例2中液晶显示面板的结构示意图。
具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
比较例1：
参图1所示，现有技术中的一种液晶显示面板包括相对设置的第一基板10'和第二基板20'、以及位于第一基板和第二基板之间的液晶层30'，其中，第一基板10'为阵列基板，第二基板20'为彩膜基板，第一基板10'上在朝向第二基板20'一侧依次设有第一公共电极11'和绝缘层12'，绝缘层12'上设置有若干阵列排布的第一像素电极13'，且第一像素电极13'为等间距分布。
本比较例中液晶显示面板是边界电场切换模式，属于水平电场型液晶显示装置中的一种。第一基板10'上的第一像素电极13'与有绝缘层12'阻隔的第一公共电极11'之间形成水平电场，但是该水平电场在第一像素电极13'的位置和两个 第一像素电极13'中间的位置会存在倾斜的分量，从而导致在第一像素电极的位置和两个第一像素电极中间的位置的液晶分子也出现倾斜，如图1虚线框内所示。出现倾斜的液晶分子会带来穿透率的下降，从而形成暗纹。
实施例1：
参图2所示，在本发明的一实施例1中，液晶显示面板包括相对设置的第一基板10和第二基板20、以及位于第一基板和第二基板之间的液晶层30。
其中，第一基板10为阵列基板，第二基板20为彩膜基板，第一基板10上在朝向第二基板20一侧依次设有第一公共电极11和绝缘层12，绝缘层12上设置有若干阵列排布的第一像素电极13，且第一像素电极13为等间距分布。
进一步地，在第二基板20在朝向第一基板10一侧设有若干第二公共电极21和第二像素电极22，第二公共电极21和第二像素电极22为间隔排列设置。
具体地，在本实施例中第二公共电极21和第二像素电极22在第二基板20上均为等间距阵列排布，第二公共电极21和第一像素电极13在垂直位置上交叉分布，同时，第二像素电极22和第一像素电极13在垂直位置上也交叉分布，即在第二基板20上对应于第一像素电极13垂直位置处不会存在第二公共电极，也不会存在第二像素电极。另，相邻第二公共电极21之间的距离与相邻第一像素电极13之间的距离相等，相邻第二像素电极22之间的距离与相邻第一像素电极13之间的距离也相等，且相邻的第二公共电极21和第二像素电极22之间的距离为相邻第一像素电极13之间距离的一半。在本实施例中，第二像素电极22和第二公共电极21沿第一像素电极13所在的轴线或相邻第一像素电极13的中轴线对称分布。
本实施例中在彩膜基板上增加了第二像素电极和第二公共电极，其位置具体设置在比较例1中暗纹正对位置的两侧，第二像素电极和第二公共电极相间 排列且在第二像素电极和第二公共电极之间形成水平电场，可以使暗纹位置处倾斜的液晶分子趋于水平方向排列。从图2中的整体效果来看，由于设计了第二像素电极和第二公共电极，彩膜基板一侧的液晶分子排列会与阵列基板一侧的液晶分子排列方向形成互补，从而提高暗纹位置处光的穿透率，进而使比较例1中的暗纹消失。
实施例2：
参图3所示，在本发明的一实施例2中，液晶显示面板同样包括相对设置的第一基板10和第二基板20、以及位于第一基板和第二基板之间的液晶层30。
其中，第一基板10为阵列基板，第二基板20为彩膜基板，第一基板10上在朝向第二基板20一侧依次设有第一公共电极11和绝缘层12，绝缘层12上设置有若干阵列排布的第一像素电极13，且第一像素电极13为等间距分布。
在第二基板20在朝向第一基板10一侧设有若干第二公共电极21和第二像素电极22，第二公共电极21和第二像素电极22为间隔排列设置。
在本实施例中，第二公共电极21和第一像素电极13在垂直位置上交叉分布，同时，第二像素电极22和第一像素电极13在垂直位置上也交叉分布，即在第二基板20上对应于第一像素电极13垂直位置处不会存在第二公共电极，也不会存在第二像素电极。相邻的第二公共电极21之间的距离与相邻的第一像素电极13之间的距离相等，同时，相邻的第二像素电极22之间的距离也与相邻的第一像素13之间的距离相等，但相邻的第二公共电极21和第二像素电极22之间的距离不等，同时，相邻的第二像素电极22和第二公共电极21沿第一像素电极13所在的轴线或相邻第一像素电极13的中轴线对称分布。
从图3中的整体效果来看，本实施例中彩膜基板一侧的液晶分子排列同样会与阵列基板一侧的液晶分子排列方向形成互补，从而提高暗纹位置处光的穿 透率，进而使比较例1中的暗纹消失。
上述实施例仅为本发明的两种优选实施例，应当理解的是，通过在彩膜基板上设置第二公共电极和第二像素电极进而使液晶显示面板或显示器中暗纹消失的各种实施方式均属于本发明的保护范围，并不限于上述两种实施例所述的情况。如，在其他实施例中，第二像素电极和第二公共电极之间的距离可以不等、或第二像素电极和第而公共电极也不一定需与第一像素电极所在轴线或其中轴线对称分布，在此不再一一举例说明。
本发明中的液晶显示面板/显示器为水平电场型液晶显示面板/显示器，如IPS、FFS液晶显示面板/显示器等。
由以上技术方案可以看出，本发明在第二基板上增加了第二像素电极和第二公共电极，第二像素电极和第二公共电极相间排列且在第二像素电极和第二公共电极之间形成水平电场，可以使暗纹位置处倾斜的液晶分子趋于水平方向排列，从而提高暗纹位置处光的穿透率，使液晶面板和显示器中的暗纹消失。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
