本申请要求于2018年3月30日提交的申请号为201810290657.4，发明名称为“彩膜基板、彩膜基板的制作方法及显示面板”的中国专利的优先权，该申请在此以引文方式整体并入本文。
技术领域
本公开涉及显示技术领域，特别是涉及一种彩膜基板、彩膜基板的制作方法及显示面板。
背景技术
在显示技术领域，液晶面板以其耗电少、轻薄、便于携带等优点占据了显示面板的市场。液晶面板包括彩膜基板、阵列基板以及位于彩膜基板和阵列基板之间的液晶层，彩膜基板和阵列基板对盒后，为了维持两者之间的盒厚，目前通常采用在彩膜基板上制造隔垫物来实现。
隔垫物分为主隔垫物和辅助隔垫物，通常主隔垫物会有一定的压缩量，支撑盒厚，处于压缩状态，而辅助隔垫物没有压缩量。当液晶面板受到过大外力的时候，辅助隔垫物才被压缩，起到辅助支撑作用。目前，在测量隔垫物的高度时，选择一个基准面作为测量参照物，实现隔垫物的测量。
发明人在实现上述过程中发现，相关技术中隔垫物在RGB子像素上无规律排布时，隔垫物高度测量时无法选择同一子像素当基准面，由于RGB子像素的膜厚存在高度差，导致测量隔垫物高度时也存在高度误差。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1和图2A和图2B为相关技术中的一种彩膜基板(ColorFilter，CF)，该彩膜基板包括：衬底基板11、行黑矩阵121、列黑矩阵122、彩膜层13。其中，衬底基板11上方设置有多行多列的行黑矩阵，所述彩膜层13设置于所述衬底基板11上。彩膜层13包含RGB多色道，每个色道包含多个颜色单元，各颜色单元之间由黑矩阵分割。所述彩膜基板中还包括位于彩膜层13上方的平坦层14。
图2A更清楚地展示了衬底基板11、行黑矩阵121、彩膜层13之间的关系。在实际应用中，彩膜层13在行黑矩阵121和列黑矩阵122围成的镂空区域间内可以连续分布，也可以不连续，呈块状分布，具体的，不做限定。
图2B为图1的彩膜基板沿图1的BB’线的剖面图。位于每个色道中的行黑矩阵121在形成彩膜层的过程中被该色道所填充的颜料所覆盖。隔垫 物随机设置在一个或多个色道的行黑矩阵上。
实际应用中，在显示面板中除了包含如图1所示的彩膜基板外，还包含隔垫物15，设置于彩膜层13之上、背向于所述黑矩阵12的一侧，而隔垫物15实际位于平坦层14正上方，且背向于黑矩阵12的一侧。图1中彩膜层13采用RGB顺序形成，在实际应用中，还可以采用BGR顺序等等，具体对彩膜层13中颜色的排序工艺不做限定。
通常，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)是由阵列基板和彩膜基板之间填充液晶并对盒而成。为了保持盒厚的均一性以及面板的稳定性，阵列基板和彩膜基板之间设置了一定数量的隔垫物15来支撑，隔垫物15对上述两个基板进行支撑以及起到缓冲作用，保持液晶处于一个相对稳定的状态，以保证显示效果。因此，准确确定隔垫物15的实际高度是液晶保持稳定的关键因素。
相关技术中，隔垫物可随机或者按照某些排列规则(如阵列)排布，在测量隔垫物高度时，就近选择彩膜层中的一个子像素区域作为基准面，并基于该基准面执行隔垫物的测量。但是，彩膜层中R色道、G色道或B色道中分别填充红色、绿色、蓝色，由于每种颜色的膜厚不同，因此，在选择基准面的时候，基准面的厚度也存在差异，进而导致测量的隔垫物高度存在误差。
为了解决相关技术中存在的问题，本公开实施例在选择基准面时，选择的是具有同一厚度的基准面，或者趋于同一高度的基准面。如图3所示，相对于该基准面所有隔垫物基准结构16形成一个水平面。可以首先确定隔垫物15的位置，在相应地确定隔垫物基准结构的位置。或者，首先确定隔垫物基准结构的位置，再将隔垫物设置在隔垫物基准结构之上。在设置隔垫物基准结构的黑矩阵上充填同一种颜色的颜料，作为测量隔垫物15高度的参照物。
一个彩膜基板中通常包含N(N大于2)个隔垫物15，因此，为了便于测量隔垫物15高度，在彩膜层13中通常至少包含N个隔垫物基准结构16，或者，也可以在一个隔垫物基准结构16上设置多个隔垫物15，或者在多个隔垫物基准结构16上设置一个隔垫物15，只要隔垫物设置在隔垫物基 准结构上即可。隔垫物基准结构的位置可以预先设定。也可在放置隔垫物的彩膜基板的对应位置设置隔垫物基准结构。所述隔垫物基准结构16形成一个平面；本公开实施例所述的隔垫物基准结构16，设置于所述黑矩阵12远离所述衬底基板11的表面；所述隔垫物基准结构16远离所述衬底基板11的表面为水平面，所述隔垫物基准结构16的所述表面用于设置隔垫物15；所有所述隔垫物基准结构16的所述表面之间的高度差小于第一阈值，该第一阈值可根据产品要求确定或者为无限小。其中，所述隔垫物基准结构16在所述衬底基板11上的正投影位于所述黑矩阵12在所述衬底基板的正投影内，且与所述彩膜层13在所述衬底基板11上的正投影不重叠。这样，可以将表面为平面的隔垫物基准结构16选作为基准面，作为隔垫物高度的基准。具体实施时，选取基准面的尺寸小于或者等于在辅助结构16的尺寸，这样可以保证基准面的准确性。
具体实施例中，所有所述隔垫物基准结构16的所述表面之间的高度差为零。
本公开实施例中，为增强隔垫物测量基准的准确性，隔垫物基准结构16的所述表面之间的高度差必须要小于第一阈值，该第一阈值的设置考虑了制作工艺过程中出现的微小误差。在本公开实施例的另一种实现过程中，为了确保测量隔垫物高度的准确性，第一阈值的设置越小，测量隔垫物15高度的准确度就越高，例如，可以设置第一阈值为趋向于0的无限小，或者，设置第一阈值为几纳米等等，具体的，本公开实施例对此不做限定。
隔垫物基准结构16形成一个平面，才能确保选择基准面时，彩膜基板中的所有基准面均有相同的高度。
图4为本公开实施例提供的一种彩膜基板沿图3中的横截线(虚线所示，图中未标号)的截面图。通过图4可以看出，在隔垫物15的正下方对应的两个隔垫物基准结构16，本实施例中，其可以采用与彩膜层中任意一种颜色相同的材料制备，这样可以在制作彩膜层的其中一种颜色时，同时制备出隔垫物基准结构16。另外，可由图4直接看出，彩膜层13的厚度大于所述黑矩阵12的厚度。
在实际应用中，隔垫物基准结构16实际位于黑矩阵12的上方，彩膜 层13上方还包含有一个平坦层14。
本公开实施例提供的彩膜基板，该彩膜基板中包含：衬底基板；设置在衬底基板上的多行多列黑矩阵；彩膜层，彩膜层设置于衬底基板上，所述彩膜层包括由所述多列黑矩阵限定出的间隔排列的多个色道，每个色道包括由所述多行黑矩阵限定出的多个颜色单元；至少一个隔垫物基准结构，每个隔垫物基准结构包括分别设置在至少相邻两列色道中、且在同一行黑矩阵上的至少两个子结构，每个子结构设置于黑矩阵远离衬底基板的表面上；所有隔垫物基准结构远离衬底基板的表面为水平面；所有隔垫物基准结构的表面之间的高度差小于第一阈值，该第一阈值可根据产品要求确定或者为无限小；其中，至少一个隔垫物基准结构在衬底基板上的正投影位于黑矩阵在衬底基板的正投影内，且与彩膜层在衬底基板上的正投影不重叠；本公开实施例中的所有隔垫物基准结构的表面之间的高度差小于第一阈值，至少一个隔垫物基准结构作为测量隔垫物的基准面，因此，将该基准面作为测量隔垫物高度的参考能够大大降低测量误差。
进一步的，作为对上述实施例的细化及扩展，隔垫物基准结构16在所述行黑矩阵121上方，且隔垫物基准结构16的尺寸，如宽度，等于彩膜层13中的与之相邻的色道上一个子像素的尺寸(如宽度)。
需要说明的是，为了确保制作隔垫物基准结构16能够拥有统一的高度，在对镂空结构填充预设颜色时，其采用的颜色的材质与制作工艺，均与彩膜层相同颜色单元所用的颜色的材料、工艺相同，确保一致性。
隔垫物15具有支撑作用，隔垫物基准结构的设置可以提高液晶显示装置整体厚度的均一性。在实际应用中，隔垫物15分为主隔垫物15和辅助隔垫物15，其中，所述主隔垫物15的高度大于所述辅助隔垫物15的高度，可随机或者按照某一排列规则设置于黑矩阵上，且所述隔垫物15位于彩膜层的第一颜色单元17(R颜色)、第二颜色单元18(G颜色)或第三颜色单元19(B颜色)中任两个子像素之间的一侧。在实际应用中，第一颜色单元17还可以为G颜色或者B颜色等，具体不进行限定，但是，为了便于说明，本公开实施例以多个第一颜色单元17组合形成R色道、多个第二颜色单元组合形成G色道，多个第三颜色单元组合形成B色道进行说明，但是 应当注意的是，该种说明方式并非易在限定颜色单元与色道之间存在绑定关系。
示例性的，如图5所示，假设彩膜基板中，设置隔垫物15的排列规则为在同一水平线上，两个色道之间设置有一个隔垫物15，并且，主隔垫物15连成的直线与每条色道垂直；若隔垫物15的排列规则符合上述说明(如图5所示的排列)，则可以在彩膜层13上设置如图5所示的隔垫物基准结构16，该隔垫物基准结构16为一矩阵，垂直于彩膜层13中的每个色道。如此设计，即便是隔垫物15稍微移动，也不会重新设置隔垫物基准结构16的位置，即不会重新选定基准面。
图5描述的内容中，所述隔垫物15在所述衬底基板11上的正投影位于所述隔垫物基准结构在所述衬底基板11上的正投影内，作为本公开实施例的另一种实现方式，可能还会存在隔垫物15仅位于两个相邻的色道之间，或者，在3个相邻的色道之间包含2个隔垫物15，也符合所述隔垫物15在所述衬底基板11上的正投影位于所述隔垫物基准结构在所述衬底基板11上的正投影内的应用场景。
图5意在说明隔垫物15以及隔垫物基准结构16为连续排布的说明方式，下述实施例中会说明一下实际应用中，隔垫物15与隔垫物基准结构16为不连续排布的应用场景，由图5可以看出，彩膜层13包括被所述黑矩阵12限定出的呈阵列排布的颜色单元(包括第一颜色单元17，第二颜色单元18，第三颜色单元19)，隔垫物基准结构16可以设置于所述第一颜色单元17、第二颜色单元或第三颜色单元中的相邻两行之间，可以进行规则排列，如，每隔两个颜色单元设置一个隔垫物15与隔垫物基准结构16，或者，每隔三个颜色单元设置一个，隔垫物15与隔垫物基准结构16。
作为本公开实施例的可实现方式，隔垫物基准结构16还可以呈阵列排布，请继续参考图5，隔垫物基准结构16成两列排布设置，实际应用中，根据需要按需设置即可，在不影响显示面板正常显示的前提下，还可设置更多列的隔垫物基准结构16，如4列或3列等，这样基准面的选取灵活性会更大。本公开实施例不作限定。
上述实施例中的隔垫物基准结构16可以设置在彩膜基板的与黑矩阵区 域对应的位置，即所述隔垫物基准结构16在所述衬底基板11上的正投影位于所述黑矩阵12在所述衬底基板11的正投影内，且与所述彩膜层13在所述衬底基板11上的正投影不重叠。在本公开实施例中，所述隔垫物基准结构在列方向上和与之相邻的颜色单元对齐，即隔垫物基准结构16包含与相邻的颜色单元的宽度相同。
本公开实施例还提供一种彩膜基板的制作方法，该方法应用于制作图1至图5中任一幅所示的彩膜基板的过程中，如图6所示，所述方法包括：
201、在衬底基板上形成黑矩阵层。
202、在衬底基板上形成彩膜层。
彩膜层中包含至少3个色道，具体实施过程中有R色道、G色道或B色道中分别填充红色、绿色、蓝色，每个色道中由多个颜色单元(或者子像素)组成，用于对不同颜色的光线进行过滤。
203、形成至少一个隔垫物基准结构。
所述所有隔垫物基准结构设置于所述黑矩阵远离所述衬底基板的表面；所述所有隔垫物基准结构远离所述衬底基板的表面为水平面；所述所有隔垫物基准结构的所述表面之间的高度差小于第一阈值。
本公开实施例中，隔垫物基准结构的所述表面之间的高度差必须要小于第一阈值，第一阈值可根据产品要求确定或者为无限小，如此设计的目的在于增强测量高度的准确性。第一阈值的设置其目的在于，为了防止制作工艺过程中出现的微小误差。在本公开实施例的另一种实现过程中，为了确保隔垫物基准结构的高度统一，第一阈值的设置越小，测量隔垫物高度的准确度就越高，例如，可以设置第一阈值为趋向于0的无限小，或者，设置第一阈值为0.1纳米等等，具体的，本公开实施例对此不做限定。
本公开实施例提供的彩膜基板的制作方法，该彩膜基板中包含：衬底基板以及设置在衬底基板上的黑矩阵；彩膜层，彩膜层设置于衬底基板上；至少一个隔垫物基准结构，设置于黑矩阵远离衬底基板的表面；所有隔垫物基准结构远离衬底基板的表面为水平面；所有隔垫物基准结构的表面之间的高度差小于第一阈值，第一阈值可根据产品要求确定或者为无限小；其中，隔垫物基准结构在衬底基板上的正投影位于黑矩阵在衬底基板的正 投影内，且与彩膜层在衬底基板上的正投影不重叠；本公开实施例中的所有隔垫物基准结构的表面之间的高度差小于第一阈值，所述隔垫物基准结构作为测量隔垫物的基准面，因此，将该基准面作为测量隔垫物高度的参考能够大大降低测量误差。
本公开实施例的目的在于确保隔垫物基准结构之间高度差的最小化，如此一来，在后续对隔垫物的高度进行测量时，能增加隔垫物高度的准确性，本公开实施例在制作彩膜基板过程中，还可采用以下可选方式，例如：确定隔垫物的预计位置，并选择与所述隔垫物的预计位置距离最近的子像素。实际应用中，在确定隔垫物的预计位置时，可以采用但不局限于以下两种方式：方式一，根据彩膜基板中的坐标进行确定，其中，彩膜基板的左上角为坐标原点。方式二，根据与彩膜层的相对位置进行确定，彩膜层中每条色道均有唯一标识。本公开实施例对确定隔垫物的预计位置不作限定。
在确定选择与所述隔垫物的预计位置距离最近的子像素之后，可以在所述子像素的对应的区域内形成隔垫物基准结构，以提高后续测量隔垫物高度的速度和准确性。
本公开实施例中，在所述彩膜层中形成有被所述黑矩阵限定出的呈阵列排布的第一颜色单元、第二颜色单元及第三颜色单元，这些颜色单元构成彩膜层中的不同色道。所述隔垫物基准结构设置于所述第一颜色单元、第二颜色单元或第三颜色单元中的相邻两行之间。
在步骤203执行形成多个隔垫物基准结构时，可以包括但不限于以下方式实现，如采用所述第一颜色单元、第二颜色单元或者第三颜色单元中的任一种构图工艺，形成所述隔垫物基准结构，以确保一致性，也即是所述隔垫物基准结构和所述第一颜色单元或者第二颜色单元、或者第三颜色单元采用同一个构图工艺形成，本公开实施例所述的构图工艺至少包含用同一掩膜板进行曝光、显影等。进一步，所述隔垫物基准结构与所述第一颜色单元或者第二颜色单元、或者第三颜色单元采用相同的材料，以便简化工艺。
进一步的，本公开实施例还提供一种显示面板，包括隔垫物及彩膜基 板；其中，所述彩膜基板为图1至图5中任一幅所述的彩膜基板。
所述隔垫物位于黑矩阵所在的区域内，以便不影响正常显示。
