具体实施方式
现在将参考附图更全面地描述示例实施例。然而，示例实施例能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施例使得本公开将更加全面和完整，并将示例实施例的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。在下面的描述中，提供许多具体细节从而给出对本公开的实施例的充分理解。

相关技术中，彩膜基板可以包括依次层叠设置的衬底基板、黑矩阵层和彩膜层，其中，黑矩阵层形成有阵列设置的多个透光窗口。图1为相关技术中黑矩阵层和彩膜层的俯视示意图，其中，虚线矩形框为被彩膜层覆盖的透光窗口201。参见图1，彩膜层可以包括沿行方向A周期性排列的红色色阻条1、绿色色阻条2和蓝色色阻条3，任意一个色阻条沿列方向B延伸并覆盖沿第二方向直线排列的多个透光窗口201。如此，各个透光窗口201被各个色阻条所覆盖。
发明人经过长期和大量试验发现，在窄边框液晶显示面板中，由于密封区域比较窄，黑矩阵层容易暴露于环境；暴露于环境中的黑矩阵层会作为介质而将外界的电荷导入显示 面板内部，这些导入的电荷将会聚集在色阻条上，尤其是容易聚集于绿色色阻条2上；聚集于色阻条上的电荷与阵列基板的像素电极之间会产生垂直于衬底基板方向的电动势，在该电动势的作用下，液晶可以发生旋转，进而导致L0画面下显示发绿的不良。
不仅如此，液晶显示面板的驱动基板上设置有大量的金属图形；当驱动基板驱动显示面板时，这些金属图形需要负载高压信号，尤其是行方向的栅极引线(Gate)需要负载高压信号，这会通过耦合相应导致彩膜层的黑矩阵层和彩膜层产生静电，进而使得显示面板的边缘偏红和显示区偏绿。
为了解决该不良，本公开提供一种彩膜基板，图3为该彩膜基板的俯视结构示意图，图2为该彩膜基板沿T-T位置的剖切示意图，图4为该彩膜基板的各个色阻单元的排布示意图。如图2、图3和图4所示，该彩膜基板包括衬底基板100、黑矩阵层200和彩膜层300，其中，
彩膜层300，设于衬底基板100的一侧，包括阵列分布的多个色阻单元310；多个色阻单元310形成有多个色阻行304、多个第一色阻列301、多个第二色阻列302和多个第三色阻列303；其中，任意一个色阻行304包括沿行方向A周期排列的第一色阻单元311、第二色阻单元312和第三色阻单元313；任意一个第一色阻列301由多个第一色阻单元311组成；任意一个第二色阻列302由多个第二色阻单元312组成；任意一个第三色阻列303由多个第三色阻单元313组成；彩膜层300还包括至少一个填充部320，填充部320位于色阻行304之间，且填充部320的厚度与多个色阻单元310中的至少一个的厚度相同；
黑矩阵层200设于彩膜层300与衬底基板100之间，且包括多个透光窗口201(在图3中，透光窗口201因被彩膜层遮挡而以虚线框表示)；各个透光窗口201被各个色阻单元310一一对应地覆盖。
本公开提供的彩膜基板中，各个色阻单元310呈现阵列设置，相较于相关技术中采用色阻条的方式可以减小色阻单元310与黑矩阵层200的交叠面积，进而减小黑矩阵层200上的电荷向色阻单元310转移的程度，能够减小或者消除0灰阶(L0)画面下色阻单元310与像素电极之间的电势差，进而减小或者消除L0画面下显示面板发绿的不良。不仅如此，该彩膜层300还设置有填充部320，该填充部320远离衬底基板100的一侧可以用于形成支撑柱401，避免直接在黑矩阵层200远离衬底基板100的表面直接形成支撑柱401而导致的制备难度过大的问题；由于填充部320厚度与多个色阻单元310中的至少一个相同，因此应用该彩膜基板的显示面板的液晶盒的盒厚能够更均匀。
下面结合附图对本公开实施方式提供的阵列基板的各部件进行详细说明：
衬底基板100可以为无机材料的透明衬底基板100，也可以为有机材料的透明衬底基板100。举例而言，在本公开的一种实施方式中，衬底基板100的材料可以为钠钙玻璃(soda-lime glass)、石英玻璃、蓝宝石玻璃等玻璃材料。在本公开的另一种实施方式中，衬底基板100的材料可以为聚甲基丙烯酸甲酯(Polymethyl methacrylate，PMMA)、聚乙烯醇(Polyvinyl alcohol，PVA)等，本公开对此不做特殊的限定。
黑矩阵层200设置于衬底基板100的一侧，其可以采用不透光材料制备而成。举例而言，在本公开的一种实施方式中，黑矩阵层200可以采用黑色光刻胶材料或者黑色树脂材料。黑矩阵层200包括多个透光窗口201，显示面板的光线通过透光窗口201出射而实现显示画面。
如图2和图3所示，彩膜层300设置于黑矩阵层200远离衬底基板100的一侧，且包括多个色阻单元310，各个色阻单元310与各个透光窗口201一一对应设置，且任意一个色阻单元310覆盖对应的透光窗口201。
在本公开的一种实施方式中，在液晶显示面板中，与彩膜基板配合的驱动基板的栅极引线位于透光窗口201之间。尤其是，各个透光窗口201形成多个沿行方向A直线排列的透光窗口201行，栅极引线在黑矩阵层200上的正投影可以位于各个透光窗口201行之间。如此，由于各个色阻单元310不再采用色阻条的设置方式，尤其是第三色阻单元313不再采用色阻条的设置方式，因此色阻单元310与栅极引线的交叠面积减小，可以进一步降低栅极引线通过耦合而导致色阻单元310带电的能力，减少色阻单元310上的电量。
在本公开中，各个色阻单元310与各个透光窗口201一一对应设置指的是，每一个色阻单元310均只有一个透光窗口201与之对应，且每一个透光窗口201均只有一个色阻单元310与之对应。可以理解的是，任意一个透光窗口201在衬底基板100上的正投影，位于对应的色阻单元310在衬底基板100上的正投影以内。
在本公开的一种实施方式中，色阻单元310可以填充对应的透光窗口201，以实现对透光窗口201的完全覆盖。
本公开的彩膜基板中，如图4所示，各个色阻单元310可以呈Real RGB的排布方式。示例性的，沿同一行方向A直线排列的各个色阻单元310形成色阻行304，因此彩膜层300的各个色阻单元310可以形成有多个色阻行304；任意一个色阻行304可以包括周期排列的第一色阻单元311、第二色阻单元312和第三色阻单元313。沿同一列方向B直线排列的各个色阻单元310形成色阻列，因此彩膜层300的各个色阻单元310可以形成有多个色阻列。其中，任意一个色阻列上的色阻单元310为同一颜色的色阻单元310。根据色阻列中色阻单元310的不同，彩膜层300的各个色阻单元310形成有多个第一色阻列301、多个第二色阻列302和多个第三色阻列303；其中，任意一个第一色阻列301由多个第一色阻单元311组成；任意一个第二色阻列302由多个第二色阻单元312组成；任意一个第三色阻列303由多个第三色阻单元313组成。
可选地，第一色阻单元311可以为红色色阻单元，第二色阻单元312可以为蓝色色阻单元，第三色阻单元313可以为绿色色阻单元。可选地，相对于绿色色阻单元和蓝色色阻单元，红色色阻单元可以具有更高的物理化学稳定性，其更不容易失效或者被破坏。优选地，在本公开的一种实施方式中，如图3所示，填充部320可以包括第一填充部321，第一填充部321采用与红色色阻单元相同的材料，以提高彩膜层300的物理化学稳定性。
可选地，红色色阻单元的透光率低于绿色色阻单元和蓝色色阻单元。举例而言，红色 色阻单元的透光率一般为20％左右，而绿色色阻单元和蓝色色阻单元的透光率可以达到60％以上。
填充部320可以设置于黑矩阵层200远离衬底基板100的表面。可以理解的是，参见图3，填充部320在衬底基板100上的正投影，位于黑矩阵层200在衬底基板100的正投影以内。
在本公开中，色阻单元310的厚度指的是色阻单元310远离衬底基板100的表面与黑矩阵层200远离衬底基板100的表面之间的距离。在本公开的一种实施方式中，当色阻单元310填充透光窗口201时，色阻单元310的色阻材料在透光窗口201处的厚度为色阻单元310的厚度与透光窗口201的深度之和。
在本公开的一种实施方式中，在本公开提供的彩膜基板中，如图5所示，填充部320可以包括多个第一填充部321；各个第一填充部321可以相互连接以形成一个整体，以提高第一填充部321对各个色阻行304之间的间隙的填充程度。
可选地，第一填充部321的材料和厚度，与第一色阻单元311的材料和厚度相同。如此，可以在同时制备第一填充部321和第一色阻单元311，减少彩膜基板的制备工序并减少所需的掩膜板数量。
当第一色阻单元311的透光率低于第二色阻单元312和第三色阻单元313时，还可以使得各个第一填充部321以及各个第一色阻单元311相互连接。如此，可以进一步提高彩膜层300对黑矩阵层200的覆盖率，便于支撑柱层400等后续膜层的制备，也便于使得液晶盒的盒厚均匀。由于第一色阻单元311的透光率低，因此即便电荷从黑矩阵层200向第一色阻单元311转移而导致液晶在L0画面下偏转漏光，由于漏出的光线需要穿过较低透光率的第一色阻单元311，不会导致显示面板呈现出明显的发光现象。如此，可以实现在降低显示面板在L0画面下发光与便于后续膜层的制备方面达成平衡，既降低了显示面板在L0画面下发光的程度，又避免了彩膜层300的改进对后续膜层制备的不利影响。
优选地，如图5和图6所示，各个第一填充部321以及各个第一色阻单元311相互连接以形成第一色阻图案330，第一色阻图案330包括有多个暴露窗口350，任意一个暴露窗口350暴露两个相邻设置的透光窗口201；同一暴露窗口350所暴露的透光窗口201分别被第二色阻单元312和第三色阻单元313覆盖。换言之，同一暴露窗口350内仅设置有一个第二色阻单元312和一个第三色阻单元313。优选地，同一暴露窗口350内的第二色阻单元312和第三色阻单元313沿行方向A相邻设置。如此，可以便于第一色阻图案330的制备，避免在相邻设置的两个不同颜色的子像素之间的间隙中设置第一色阻图案330，进而避免对准偏差而导致的第一色阻图案330与第二色阻单元312或第三色阻单元313的部分交叠，便于均匀显示面板的液晶盒厚度。
可选地，暴露窗口350可以为矩形窗口，即暴露窗口350在衬底基板100上的正投影为矩形。如此，可以便于第一色阻图案330的制备。
举例而言，第一色阻单元311为红色色阻单元，即第一色阻图案330采用红色色阻材 料；任意一个暴露窗口350暴露沿行方向A相邻设置的两个透光窗口201；同一暴露窗口350所暴露的两个透光窗口201分别被绿色色阻单元和蓝色色阻单元覆盖。如此，在本公开提供的彩膜基板中，各个绿色色阻单元和蓝色色阻单元均呈岛状设计，红色色阻单元和第一填充部321形成的第一色阻图案330呈现为红色色阻材料组成的网格状。
在本公开的另一种实施方式中，如图7所示，沿行方向A，任意相邻的两个色阻单元310之间均设置有第一填充部321。换言之，任意一个第一色阻列301的相邻两个第一色阻单元311之间设置有第一填充部321；任意一个第二色阻列302的相邻两个第二色阻单元312之间设置有第一填充部321；任意一个第三色阻列303的相邻两个第三色阻单元313之间设置有第一填充部321。如此，可以提高第一填充部321的覆盖面积，便于均匀显示面板的液晶盒厚度。优选地，第一填充部321的材料和厚度与第一色阻单元311的材料和厚度相同，以在同一工艺中制备第一填充部321和第一色阻单元311。进一步地，如图8所示，沿同一行方向A设置的各个第一填充部321可以相互连接以形成一条形，以进一步提高第一填充部321的覆盖面积，进一步均匀显示面板的液晶盒厚度。
在本公开的另一种实施方式中，如图9所示，填充部320包括第一填充部321和第二填充部322，其中，第一填充部321的材料和厚度与第一色阻单元311的材料和厚度相同，第二填充部322的材料和厚度与第二色阻单元312的材料和厚度相同。该彩膜基板可以通过同一工序形成各个第一填充部321和第一色阻单元311，以及通过同一工序形成各个第二填充部322和第二色阻单元312，简化了该彩膜基板的制备工序，避免采用额外工序填充各个色阻单元310之间的间隙以为支撑柱401提供支撑。
优选地，如图9所示，同一第一色阻列301中，相邻的两个第一色阻单元311之间设置有第二填充部322；同一第二色阻列302中，相邻的两个第二色阻单元312之间设置有第一填充部321；同一第三色阻列303中，相邻的两个第三色阻单元313之间设置有第一填充部321。如此，可以减小色阻单元310与填充部320(第一填充部321和第二填充部322)之间连接的可能性，有助于减小电荷从填充部320(第一填充部321和第二填充部322)向色阻单元310转移，并有助于减小电荷在色阻单元310上的累积。
在本公开的一种实施方式中，如图10所示，彩膜基板包括边缘区域C和边缘区域围绕的中心区域D(中心区域D为图10中虚线以内区域)；在边缘区域C，任意一个填充部320与任意一个色阻单元310不相连。如此，在边缘区域C，可以避免填充部320上的电荷向色阻单元310转移，进而抑制显示面板在边缘位置的色偏。
其中，本公开实施方式中，边缘区域C呈封闭环形，可以包括彩膜层300中最外侧的一个或者多个色阻列，以及最外侧的一个或者多个色阻行。在边缘区域C内，可以包括位于色阻行之间的填充部320。中心区域D被边缘区域C环绕，使得中心区域D中的任意一个色阻单元310均不位于最外侧的色阻行或者色阻列。
可选地，第一色阻单元311的透光率低于第二色阻单元312和第三色阻单元313，在中心区域D内，各个第一填充部321以及各个第一色阻单元311相互连接以形成第二色阻 图案。在边缘区域C，第一色阻单元311和第一填充部321相互不连接，可以避免第一填充部321上的电荷向第一色阻单元311单元转移，降低显示面板的边缘色偏。在中心区域D，各个第一填充部321以及各个第一色阻单元311相互连接以形成第二色阻图案340，可以降低制备第一色阻单元311和第一填充部321时的掩膜板的复杂程度，降低彩膜基板的制备成本。
各个色阻单元310与黑矩阵层200的交叠尺寸，可以根据工艺精度等因素进行选择和确定。其中，在工艺允许的范围内，各个色阻单元310与黑矩阵层200的交叠尺寸可以尽量小，以减小黑矩阵层200上的电荷向色阻单元310的转移量，避免在L0画面时色阻单元310与像素电极之间形成电动势，或者降低L0画面时色阻单元310与像素电极之间的电动势。
在本公开的一种实施方式中，各个色阻单元310在衬底基板100上的正投影的边缘，与对应的透光窗口201在衬底基板100上的正投影的边缘之间，最小距离为0～14微米。优选地，各个色阻单元310在衬底基板100上的正投影的边缘，与对应的透光窗口201在衬底基板100上的正投影的边缘之间，最小距离为5.5～8.5微米，例如可以为7微米。
可选地，在设计彩膜基板的版图时，可以使得各个色阻单元310在衬底基板100上的正投影的边缘，与对应的透光窗口201在衬底基板100上的正投影的边缘之间，最小距离为7微米。
各个色阻单元310之间的间隙可以根据显示面板的分辨率、工艺精度等需求进行设置，一般而言，显示面板的分辨率越高、对位精度越高等，各个色阻单元310之间的间隙可以越小。
在本公开的一种实施方式中，相邻两个色阻单元310之间的距离可以为0～24.5微米，优选地，相邻两个色阻单元310之间的距离可以为3.5～17.5微米，尤其是相邻两个色阻单元310之间的距离可以为9～12微米。举例而言，相邻两个色阻单元310之间的距离可以为10.5微米。可选地，在设计彩膜基板的版图时，可以使得相邻两个色阻单元310之间的距离为10.5微米。
在本公开的一种实施方式中，第二色阻单元312或第三色阻单元313与填充部320之间的距离可以为0～24.5微米，优选地，第二色阻单元312或第三色阻单元313与填充部320之间的距离可以为3.5～17.5微米，尤其是第二色阻单元312或第三色阻单元313与填充部320之间的距离可以为9～12微米。举例而言，第二色阻单元312或第三色阻单元313与填充部320之间的距离可以为10.5微米。可选地，在设计彩膜基板的版图时，可以使得第二色阻单元312或第三色阻单元313与填充部320之间的距离为10.5微米。
如图2所示，本公开提供的彩膜基板，还可以包括支撑柱层400，支撑柱层400设于彩膜层300远离衬底基板100的一侧；支撑柱层400包括多个支撑柱401，任意一个支撑柱401设于填充部320远离衬底基板100的一侧。
