Description

HVA型液晶显示面板
技术领域
本发明涉及显示技术领域，尤其涉及一种HVA型液晶显示面板。
背景技术
主动式薄膜晶体管液晶显示器(ThinFilmTransistor-LCD，TFT-LCD)近年来得到了飞速的发展和广泛的应用。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组(backlightmodule)。通常液晶显示面板由彩膜基板(CF，ColorFilter)、薄膜晶体管基板(TFT，ThinFilmTransistor)、夹于彩膜基板与薄膜晶体管基板之间的液晶(LC，LiquidCrystal)及密封框胶(Sealant)组成；其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。
就目前主流市场上的TFT-LCD显示面板而言，可分为三种类型，分别是扭曲向列(TwistedNematic，TN)或超扭曲向列(SuperTwistedNematic，STN)型，平面转换(In-PlaneSwitching，IPS)型、及垂直配向(VerticalAlignment，VA)型。其中VA型液晶显示器相对其他种类的液晶显示器具有极高的对比度，在大尺寸显示，如电视等方面具有非常广的应用。而高垂直排列(HighVerticalAlignment，HVA)模式是VA模式中一个重要的分支。HVA型液晶显示面板工作时是由阵列基板侧的像素电极和彩膜基板侧的公共电极形成的垂直电场来控制液晶层的液晶分子的旋转。
通常液晶显示面板中CF基板面向TFT基板一侧设有黑色矩阵，如图1所示，现有一种液晶显示面板，包括上基板100、下基板200、及设于上基板100与下基板200之间的液晶层300，所述上基板100包括第一基板110、设于第一基板110上的黑色矩阵120、彩色滤光层、及公共电极层140，其中彩色滤光层包括红色色阻块131、绿色色阻块132、及蓝色色阻块；所述下基板包括第二基板210、设于第二基板210上的栅极扫描线及数据线220、钝化层230、及钝化层230上的像素电极层，其中，所述栅极扫描线及数据线220围成数个子像素区域，所述像素电极层对应每个子像素区域具有一个像素电极240，像素电极240在每个子像素内被划分为多个区域，如米字型像素电极，而所述公共电极层140为连续不间断的平面型公共电极；所述红色色阻块131、绿色色阻块132、及蓝色色阻块分别对应子像素区域设置。
液晶显示技术在发展，无论是出于节约成本的考虑还是曲面设计的考虑，把CF基板侧的黑色矩阵去掉，都是技术发展的一个趋势。但是如果没有黑色矩阵就会出现显示品质的问题。如图2所示，液晶面板不包括黑色矩阵，在暗态条件下，像素电极240和公共电极140的电位相同，所以在子像素内不会出现漏光，但是在数据线220上的电位和公共电极140的电位不同的情况下，就有可能形成电场，从而驱动液晶偏转，导致漏光；如图3所示，液晶在300在数据线220和公共电极140所形成电场的驱动下发生偏转，从而导致子像素区域边缘漏光现象的发生。另外，在TFT基板与CF基板对位出现偏差的情况下，液晶面板不包括黑色矩阵，则容易出现色偏的问题，如图4所示，CF基板100与TFT基板200对位发生偏差，像素电极240本来是驱动绿色子像素中的液晶，使得画面为绿色，但是由于对位偏差，像素电极240的电场有可能影响到红色子像素边缘的液晶，导致绿色画面中混入一点红色，出现色偏。同理，在液晶面板的栅极扫描线处也会出现以上相同的情况。
发明内容
本发明的目的在于提供一种HVA型液晶显示面板，公共电极层对应栅极扫描线、及数据线的上方设有镂空部，能够防止子像素区域边缘漏光及色偏现象的发生，从而代替黑色矩阵实现遮光作用。
为实现上述目的，本发明提供一种HVA型液晶显示面板，包括上基板、下基板、及设于上基板与下基板之间的液晶层；
所述上基板包括第一基板、及设于第一基板上面对下基板一侧的公共电极层；
所述下基板包括第二基板、设于第二基板上的数条栅极扫描线、及数条数据线；
所述数条栅极扫描线、及数条数据线纵横交错围出数个子像素区域；所述数条栅极扫描线、及数条数据线位于所述数个子像素区域的边缘处；
所述公共电极层上对应所述栅极扫描线、及数据线的上方设有镂空部，所述镂空部与栅极扫描线、及数据线之间的区域无电场产生，从而避免因该区域的液晶被驱动而导致的子像素区域边缘漏光及色偏现象的发生，进而代替黑色矩阵实现遮光作用。
所述下基板还包括设于第二基板上的钝化层、及设于钝化层上的像素电极层，所述像素电极层对应每个子像素区域具有一个像素电极；所述子像素区域包括红色子像素区域、绿色子像素区域、及蓝色子像素区域。
所述上基板还包括设于第一基板及公共电极层之间的彩色滤光层，所述彩色滤光层对应所述红色子像素区域、绿色子像素区域、及蓝色子像素区域分别设有红色色阻块、绿色色阻块、及蓝色色阻块。
所述下基板还包括设于钝化层上的彩色滤光层，所述彩色滤光层对应所述红色子像素区域、绿色子像素区域、及蓝色子像素区域分别设有红色色阻块、绿色色阻块、及蓝色色阻块。
所述公共电极层上的镂空部在所述下基板上的投影完全覆盖所述数据线。
所述公共电极层上的镂空部在所述下基板上的投影完全覆盖所述栅极扫描线。
所述公共电极层、及像素电极层的材料为ITO。
所述公共电极层的镂空部通过光罩经由黄光制程形成。
所述像素电极层为图案化电极层，在每个子像素区域内所述像素电极被划分为多个域。
所述第一基板、第二基板均为玻璃基板。
本发明的有益效果：本发明的HVA型液晶显示面板，上基板上的公共电极层上对应栅极扫描线、及数据线的上方设有镂空部，使得数据线及栅极扫描线上方无公共电极与其相对，子像素区域的边缘区无法形成电场，避免了位于子像素区域边缘的液晶受电场驱动而转动，有效防止了子像素区域边缘漏光及色偏现象的发生，从而代替黑色矩阵实现遮光作用。

具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图5至图7，本发明提供一种HVA型液晶显示面板，包括上基板1、下基板2、及设于上基板1与下基板2之间的液晶层3；
所述上基板1包括第一基板11、及设于第一基板11上面对下基板2一侧的公共电极层12；
所述下基板2包括第二基板21、设于第二基板21上的数条栅极扫描线、及数条数据线22；
所述数条栅极扫描线、及数条数据线22纵横交错围出数个子像素区域；所述数条栅极扫描线、及数条数据线22位于所述数个子像素区域的边缘处。
所述公共电极层12上对应栅极扫描线、及数据线22的上方设有镂空部121，使得数据线及栅极扫描线上方无公共电极与其相对，即所述镂空部121与栅极扫描线、及数据线22之间的区域无电场产生，从而避免因该区域的液晶被驱动而导致的漏光及色偏现象的发生，进而代替黑色矩阵实现遮光作用。
具体的，所述第一基板11、第二基板22均为玻璃基板。
具体的，所述公共电极层12的材料为ITO；所述公共电极层12的镂空部121通过光罩经由黄光制程形成。
具体的，所述公共电极层12上的镂空部121在所述下基板2上的投影完全覆盖所述数据线22、及栅极扫描线，以保证所述数据线22、及栅极扫描线与公共电极层12之间的区域无电场产生。
具体的，所述下基板2还包括设于第二基板21上的钝化层23、及设于钝化层23上的像素电极层，所述像素电极层对应每个子像素区域具有一个像素电极24；所述子像素区域包括红色子像素区域、绿色子像素区域、及蓝色子像素区域；所述像素电极层为图案化电极层，在每个子像素区域内所述像素电极24被划分为多个区域。具体的，所述像素电极层的材料为ITO。
具体的，所述上基板1还包括设于第一基板11及公共电极层12之间的彩色滤光层，所述彩色滤光层对应所述红色子像素区域、绿色子像素区域、及蓝色子像素区域分别设有红色色阻块141、绿色色阻块142、及蓝色色阻块；
或者，彩色滤光层设于下基板2上，即该液晶面板也可以为COA型液晶显示面板，则所述下基板2包括设于钝化层23上的彩色滤光层，所述彩色滤光层对应所述红色子像素区域、绿色子像素区域、及蓝色子像素区域包括红色色阻块、绿色色阻块、及蓝色色阻块。
如图5所示，本发明中，公共电极层12上对应栅极扫描线、及数据线22的上方设有镂空部121，即相当于将现有液晶面板中位于黑色矩阵正下方的公共电极的部分刻蚀掉，从而使得该区域内无法形成电场，该处液晶无法受电场驱动，那么该区域的偏振光就永远无法透过这个区域的液晶，从而起到和黑色矩阵相同的作用。另外如图6所示，在上下基板对位产生偏差时，属于绿色子像素区域的像素电极24偏移至红色色阻块和绿色色阻块交接的区域时，其上方也无相应的公共电极与之形成电场，从而不会影响红色子像素区域的液晶，因此不会产生色偏。
图7是本发明的液晶显示面板内的液晶在高电压下的液晶转动形态示意图。和现有的液晶面板结构相比，本发明的液晶面板内处于子像素区域边缘部分的液晶基本上可以不受电场的作用，而处于垂直的状态。
综上所述，本发明的HVA型液晶显示面板，上基板上的公共电极层对应栅极扫描线、及数据线的上方设有镂空部，使得数据线及栅极扫描线上方无公共电极与其相对，子像素区域的边缘无法形成电场，避免了子像素区域边缘的液晶受电场驱动而转动，有效防止了子像素区域边缘漏光及色偏现象的发生，从而代替黑色矩阵实现遮光作用。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明后附的权利要求的保护范围。
