Description

COA阵列基板以及液晶显示面板 技术领域
本发明涉及显示器技术领域，尤其涉及一种COA阵列基板以及包含该COA阵列基板的液晶显示面板。
背景技术
液晶显示装置(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。如：液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等。
液晶显示装置通常包括壳体、设于壳体内的液晶显示面板及设于壳体内的背光模组(Backlight module)。其中，液晶显示面板的结构主要是由一薄膜晶体管阵列(Thin Film Transistor Array，TFT Array)基板、一彩色滤光片(Color Filter，CF)基板、以及配置于两基板间的液晶层(Liquid Crystal Layer)所构成，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。
COA(Color-filter on Array)技术是一种将彩色滤光层直接制作在阵列基板上的一种集成技术，而彩膜基板上只设有黑色矩阵(Black Matrix，BM)以及柱状隔垫物(PhotoSpacer，PS)层。COA技术能够有效解决液晶显示装置对盒工艺中因对位偏差造成的漏光等问题，并能显著提升显示开口率。
COA技术中，将彩色滤光层直接制作在阵列基板上，增加了工艺难度，尤其是彩色滤光层中残留的气体渗入到液晶层中形成气泡(Bubble)的问题。具体地，彩色滤光层的主体材料为有机物，现有技术在进行彩色滤光层的制作时，不可避免地会在其内部残存有气体，同时由于有机物的特性，在某些条件下，例如长期处于高温环境，或高压环境，或受到外力冲击，或显示器处于震动的工作状态下时，彩色滤光层内部会缓慢释放出小分子的碳氧化物气体，如CO、CO2等，这些小分子气体产生后会穿透彩色滤光层表面的较薄膜层(例如钝化层、配向膜层等)，进入到液晶层当中，在局部形成气泡，会影响显示效果，降低产品良率。因此，对于COA技术，如何避免彩色滤光层中的气体渗入到液晶层中 形成气泡是业内亟待解决的问题。
发明内容
鉴于现有技术存在的不足，本发明提供了一种COA阵列基板，可以有效地减少彩色滤光层中残留的气体渗入到液晶层中形成气泡缺陷。
为了达到上述的目的，本发明采用了如下的技术方案：
一种COA阵列基板，包括衬底基板以及阵列设置在所述衬底基板上的多个像素结构，其中，所述像素结构中设置有彩色滤光层，所述彩色滤光层包括第一部分和第二部分，第一部分彩色滤光层对应覆盖所述像素结构的显示区域，第二部分彩色滤光层对应覆盖所述像素结构的非显示区域；所述第二部分彩色滤光层中设置有透气孔。
其中，所述透气孔在所述第二部分彩色滤光层的厚度方向上贯穿所述第二部分彩色滤光层。
其中，所述透气孔的数量为多个，多个所述透气孔相互间隔其等间距分布。
其中，所述透气孔的形状为圆形或方形。
其中，所述透气孔的形状为圆形，其截面的直径为3～6μm。
其中，所述透气孔的形状为方形，其截面的边长为3～6μm。
其中，所述像素结构还包括设置于所述衬底基板上的薄膜晶体管和像素电极，所述薄膜晶体管上覆设有第一钝化层，所述彩色滤光层设置于所述第一钝化层上，所述彩色滤光层上覆设有第二钝化层，所述像素电极设置于所述第二钝化层上；其中，所述像素电极通过设置在所述第一钝化层、彩色滤光层以及第二钝化层中的过孔电性连接到所述薄膜晶体管。
其中，所述像素结构被设置为红色子像素、绿色子像素或蓝色子像素，所述红色子像素的彩色滤光层为红色滤光层，所述绿色子像素的彩色滤光层为绿色滤光层，所述蓝色子像素的彩色滤光层为蓝色滤光层。
其中，所述第一钝化层和第二钝化层的材料为氮化硅、氧化硅或者是氮化硅与氧化硅的组合物；所述像素电极的材料选自铟锡氧化物、铟锌氧化物、铝锡氧化物、铝锌氧化物和铟锗锌氧化物中的一种或多种。
本发明的另一方面是提供一种液晶显示面板，包括相对设置的阵列基板和 对盒基板，所述阵列基板和所述对盒基板之间设置有液晶分子，其中，所述阵列基板采用如上所述的COA阵列基板。
相比于现有技术，本发明实施例提供的COA阵列基板，通过在彩色滤光层对应覆盖非显示区域的部分设置有透气孔，首先，在制备彩色滤光层的工艺过程中，彩色滤光层内部的气体可以通过该些透气孔顺畅排出，减少彩色滤光层内部气体的残留量；其次，在封装形成完整的液晶显示面板后，若是液晶显示面板在高温冲击、高压冲击或外力震动冲击的情况下导致液晶层与彩色滤光层之间具有微小的流体通道，此时由于相对孔径较大(相对于前述微小的流体通道)的透气孔的存在，气相平衡点由液晶层的界面处转移到透气孔中，彩色滤光层内部释放出小分子气体难以渗入到液晶层中，避免了气泡缺陷的形成。

其中，所述像素结构2中设置有彩色滤光层23，由此形成COA阵列基板。具体地，如图1所示，所述薄膜晶体管21设置在衬底基板1上，所述薄膜晶体管21上覆设有第一钝化层24，所述彩色滤光层23设置于所述第一钝化层24上，所述彩色滤光层23上覆设有第二钝化层25，所述像素电极22设置于所述第二钝化层25上；其中，所述像素电极22通过设置在所述第一钝化层24、彩色滤光层23以及第二钝化层25中的过孔电性连接到所述薄膜晶体管21。
其中，所述像素结构2可以被设置为红色子像素、绿色子像素或蓝色子像素。对应地，所述红色子像素的彩色滤光层23为红色滤光层，所述绿色子像素的彩色滤光层23为绿色滤光层，所述蓝色子像素的彩色滤光层23为蓝色滤光层。其中，所述第一钝化层24和第二钝化层25的材料可以选择为氮化硅、氧化硅或者是氮化硅与氧化硅的组合物；所述像素电极22的材料可以选自铟锡氧化物、铟锌氧化物、铝锡氧化物、铝锌氧化物和铟锗锌氧化物中的一种或多种。
其中，参阅图1，所述薄膜晶体管21包括栅电极211、栅极绝缘层212、有源层213、源电极214和漏电极215。具体地，所述栅电极211形成于所述衬底基板1上，栅极绝缘层212覆设于所述栅电极211上，有源层213形成于所述栅极绝缘层212上并且相对位于栅电极211上方，源电极214和漏电极215形成于所述栅极绝缘层212上。所述源电极214和漏电极215之间相互间隔并且分别具有部分搭接在所述有源层213上，所述像素电极22电性连接到所述漏电极215。
本实施例中，所述彩色滤光层23中设置有透气孔231。具体地，参阅图1和图2，所述彩色滤光层23包括第一部分和第二部分，第一部分彩色滤光层23a对应覆盖像素结构2的显示区域，第二部分彩色滤光层23b对应覆盖像素结构2的非显示区域。其中，所述透气孔231设置在所述第二部分彩色滤光层23b中，即对应于像素结构2的非显示区域。需要说明的是，如图2中，扫描线S、数据线D和薄膜晶体管21是相对位于彩色滤光层23的下方，为了更好地示出彩色滤光层23，位于彩色滤光层23上的像素电极22在图2中未示出。
如上实施例所提供的COA阵列基板，通过在彩色滤光层对应覆盖非显示区域的部分设置有透气孔，首先，在制备彩色滤光层的工艺过程中，彩色滤光层 内部的气体可以通过该些透气孔顺畅排出，减少彩色滤光层内部气体的残留量；其次，在封装形成完整的液晶显示面板后，若是液晶显示面板在高温冲击、高压冲击或外力震动冲击的情况下导致液晶层与彩色滤光层之间具有微小的流体通道，此时由于相对孔径较大(相对于前述微小的流体通道)的透气孔的存在，气相平衡点由液晶层的界面处转移到透气孔中，彩色滤光层内部释放出小分子气体难以渗入到液晶层中，避免了气泡缺陷的形成。进一步地，透气孔设置在像素结构的非显示区域中，透气孔的轮廓不会影响像素的正常显示。
本实施例中，参阅图1和图2，所述透气孔231在所述第二部分彩色滤光层23b的厚度方向上贯穿所述第二部分彩色滤光层23b。其中，所述透气孔231的数量为多个，多个所述透气孔231相互间隔且等间距分布，如图2中仅示例性示出了若干透气孔231，并且，在另外的一些实施例中，多个所述透气孔231也可以是不等间距分布。
其中，所述透气孔231的大小、形貌和密度并不没有特别的限制。但是经过验证证明，所述透气孔231设计为方形或圆形时，其排气效果更佳。参阅图2和图3，本实施例中，所述透气孔231的形状为方形，并且，当其截面的边长D1、D2的为3～6μm范围内时，获得最优的排气效果。进一步地，在另外的一些实施例中，当透气孔231的形状为圆形，其截面的直径R的最佳取值范围是3～6μm。
进一步地，本实施例还提供了一种液晶显示面板，如图5所示，所述液晶显示面板包括相对设置的阵列基板100和对盒基板200，所述阵列基板100和所述对盒基板200之间设置有液晶分子300。其中，所述阵列基板100采用如上实施例所提供的COA阵列基板。需要说明的是，所述对盒基板200中设置有黑色矩阵(Black Matrix，BM)，黑色矩阵对应于像素结构的的非显示区域。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
