Description

一种液晶显示面板及显示装置
技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示面板及显示装置。
背景技术
随着液晶显示技术的发展，大尺寸液晶显示器需要较高的分辨率，但是分辨率的提高会影响到开口率的大小，导致透过率降低。为了满足对透过率的需求，一种高级超维场转换(AdvancedSuperDimensionSwitch，ADS)模式的液晶显示面板中，采用了氧化铟锡(IndiumTinOxide，ITO)透明电极，虽然透过率有了很大改善，但是仍不能满足需求。例如，图1所示的现有的一种ADS模式的液晶显示面板中，包括基板10，位于基板10上多个公共电极11，位于公共电极11上的像素电极12，位于该像素电极12之间的栅线13。由于设置的该栅线13与像素电极12、公共电极11所产生的电场使液晶分子转动而导致漏光，因而需要设置遮光层14，导致了透过率的降低。
发明内容
本发明实施例的目的是提供一种液晶显示面板及显示装置，用于解决液晶显示器的透过率较低的问题。
本发明实施例的目的是通过以下技术方案实现的：
一种液晶显示面板，包括阵列基板，在所述阵列基板上呈矩阵分布的多个像素电极，位于所述阵列基板上的多条栅线，彩色滤光膜；
各所述栅线位于一行像素电极所在区域且贯穿该行像素电极；
所述彩色滤光膜由多个列向的条状的单色滤光膜组成；其中，各所述单色滤光膜覆盖至少一列所述像素电极。
较佳地，各所述像素电极具有沿着第一方向延伸的第一狭缝和沿着第二方向延伸的第二狭缝。
较佳地，所述第一狭缝与所述第二狭缝分别位于所述像素电极中的上下两个区域，所述栅线被设置于上下两个区域之间的区域。
较佳地，还包括：在所述阵列基板上的多个公共电极；
所述公共电极覆盖各列所述像素电极中相邻两个像素电极之间的间隙。
较佳地，所述公共电极与栅线同层绝缘设置；且所述公共电极为沿着行方向延伸的公共电极条。
较佳地，各栅线与相邻的公共电极条之间的间隔为5μm～15μm。
较佳地，所述彩色滤光膜为红绿蓝RGB彩色滤光膜。
较佳地，所述彩色滤光膜位于所述阵列基板上。
较佳地，还包括对向基板，所述彩色滤光膜位于所述对向基板上。
一种显示装置，包括以上任一所述的液晶显示面板。
本发明实施例的有益效果如下：
本发明实施例提供的一种液晶显示面板及显示装置中，由于栅线贯穿一行像素电极，一方面，栅线与像素电极所产生的电场就会被像素电极所屏蔽，进而无法对附近的液晶分子产生影响，就不会出现漏光问题，进而在栅线处无需设置遮光层，另一方面，与现有技术相比，在相邻的像素电极之间没有栅线，不会出现因栅线的存在导致的漏光问题，因而在相邻的像素电极之间的间隙处也无需设置遮光层，从而提高了开口率，使得透过率提高，提高了显示质量。另外，在同一列像素电极上方覆盖了单色滤光膜，保证同一列像素电极之间的间隙处与像素电极处的滤光颜色一致，以进一步提高显示质量。

具体实施方式
下面结合附图和实施例对本发明提供的一种液晶显示面板及显示装置进行更详细地说明。
本发明实施例提供一种液晶显示面板，如图2所示，包括阵列基板20，在阵列基板20上呈矩阵分布的多个像素电极21，位于阵列基板20上的多条栅线22，彩色滤光膜23；
各栅线22位于一行像素电极21所在区域且贯穿该行像素电极21；
彩色滤光膜23由多个列向的条状的单色滤光膜231组成；其中，各单色滤光膜231覆盖至少一列像素电极21。
本发明实施例中，由于栅线22贯穿一行像素电极21，一方面，栅线22与像素电极21所产生的电场就会被像素电极21所屏蔽，进而无法对附近的液晶分子产生影响，就不会出现漏光问题，进而在栅线22处无需设置遮光层，另一方面，与现有技术相比，在相邻的像素电极21之间没有栅线，不会出现因栅线的存在导致的漏光问题，因而在相邻的像素电极21之间的间隙处也无需设置遮光层，从而提高了开口率，使得透过率提高，提高了显示质量。另外，在同一列像素电极21上方覆盖了单色滤光膜231，保证同一列像素电极21之间的间隙处与像素电极21处的滤光颜色一致，以进一步提高显示质量。
其中，上述像素电极21可以为双筹结构：各像素电极21具有沿着第一方向延伸的第一狭缝和沿着第二方向延伸的第二狭缝。
较佳地，如图3所示，第一狭缝211与第二狭缝212分别位于像素电极21中的上下两个区域，栅线22被设置于上下两个区域之间的区域。
本实施例中，栅线22位于具有双筹结构的像素电极21中间没有狭缝的区域，以保证像素电极21对栅线22与像素电极21所产生的电场起到屏蔽作用。
较佳地，上述相关实施例所述的液晶显示面板中，如图4所示，还包括：在阵列基板上的多个公共电极24；公共电极24覆盖各列像素电极21中相邻两个像素电极21之间的间隙。
当然，栅线22与公共电极24所产生的电场也会被像素电极21所屏蔽。
较佳地，公共电极24与栅线22同层绝缘设置；且公共电极24为沿着列方向延伸的公共电极条。
上述实施例中，为了避免栅线22与公共电极24之间发生短路，栅线与公共电极24之间设置预定的距离。
较佳地，各栅线22与相邻的公共电极条之间的间隔为5μm～15μm。
较佳地，上述彩色滤光膜可以但不限于为红绿蓝(RedGreenBlue，RGB)彩色滤光膜。
较佳地，上述彩色滤光膜位于阵列基板上。
较佳地，上述相关实施例所述的液晶显示面板中，还包括对向基板，彩色滤光膜位于对向基板上。
较佳地，本发明实施例中的液晶显示面板可以但不限于为ADS模式的液晶显示面板。
下面以RGB彩色滤光膜为例，对本发明实施例提供的一种液晶显示面板进行更加详细地说明。
如图5所示的液晶显示面板中，包括阵列基板20，在阵列基板20上呈矩阵分布的多个像素电极21，位于阵列基板20上的多条栅线22，彩色滤光膜23，以及在阵列基板上的多个公共电极24。
其中，各栅线22位于一行像素电极21所在区域且贯穿该行像素电极21。
其中，各像素电极21具有沿着第一方向延伸的第一狭缝211和沿着第二方向延伸的第二狭缝212；且第一狭缝211与第二狭缝212分别位于像素电极21中的上下两个区域，栅线22被设置于上下两个区域之间的区域。
其中，公共电极24为沿着列方向延伸的公共电极条，覆盖各列像素电极21中相邻两个像素电极21之间的间隙。并且，公共电极24与栅线22同层绝缘设置；各栅线22与相邻的公共电极条之间的间隔为5μm～15μm。
其中，彩色滤光膜为RGB彩色滤光膜，且位于对向基板(图5中未示出)上，由多个列向的条状的单色滤光膜231(即红色滤光膜、绿色滤光膜、蓝色滤光膜)组成；其中，各单色滤光膜231覆盖一列像素电极，按照红色滤光膜、绿色滤光膜、蓝色滤光膜的顺序依次设置。
其中的对向基板为彩膜基板。
本实施例中，液晶显示面板为ADS模式。
本实施例中的液晶显示面板所达到的效果，与上述现有技术中的液晶显示面板所达到的效果对比如下：
在未对像素电极和公共电极进行通电时，在垂直栅线的方向上，以某一条栅线的一侧为起始位置，对栅线及其附近区域，测得的光的透过率情况如图6所示：虚线为现有技术中的液晶显示面板的效果，加粗实线为本实施例的液晶显示面板的效果。其中，栅线的宽度为26μm，由于栅线不透光，因而，该部分区域透过率为零。而栅线附近的区域，通过对比可知，对于现有技术中的液晶显示面板，测量到的透过率大于零，表明栅线与像素电极、公共电极之间所产生的电场对液晶分子产生影响，使其发生转动而导致漏光；本实施例中，测量到的透过率为零，表明像素电极21对栅线22与像素电极21、公共电极24所产生的电场起到了屏蔽作用，液晶分子未发生转动，因而未发生漏光，彩膜基板上也就无需设置对应的黑矩阵遮光，提高了透过率。
未对像素电极和公共电极进行通电时，对于相邻像素电极之间的区域，现有技术中的液晶显示面板中，相邻像素电极之间的区域，即栅线及其附近的区域，从图6中可以看出，测量到的透过率大于零，表明液晶分子发生转动而导致漏光。而本实施例中的液晶显示面板中，对相邻像素电极之间的区域，实际测量到的透过率为零，表明液晶分子未发生转动，因而未发生漏光，彩膜基板上也就无需设置对应的黑矩阵遮光，提高了透过率。
在对像素电极21和公共电极24进行通电时，由于单色滤光膜231覆盖了一列像素电极21，相邻的像素电极21之间的区域光的颜色与像素电极21所在区域的光的颜色一致，提高了显示质量。
基于同样的发明构思，本发明实施例还提供一种显示装置，包括以上任意实施例所述的液晶显示面板。
本发明实施例提供的一种液晶显示面板及显示装置中，由于栅线贯穿一行像素电极，一方面，栅线与像素电极所产生的电场就会被像素电极所屏蔽，进而无法对附近的液晶分子产生影响，就不会出现漏光问题，进而在栅线处无需设置遮光层，另一方面，与现有技术相比，在相邻的像素电极之间没有栅线，不会出现因栅线的存在导致的漏光问题，因而在相邻的像素电极之间的间隙处也无需设置遮光层，从而提高了开口率，使得透过率提高，提高了显示质量。另外，在同一列像素电极上方覆盖了单色滤光膜，保证同一列像素电极之间的间隙处与像素电极处的滤光颜色一致，以进一步提高显示质量。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
