具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本公开将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
参照图1所示的现有技术柔性或曲面显示面板在弯曲时阵列基板和彩膜基板发生滑动的模拟结构示意图，柔性或曲面显示面板在弯曲时由于阵列基板1和彩膜基板2均发生滑动，上层基板向两侧滑动，下层的基板向中心滑动，引起阵列基板1上的像素电极和彩膜基板2上的开口区发生位置滑动，导致驱动某一像素时其他像素也会被驱动的现象；如驱动绿色像素时，红色或蓝色开口区的液晶发生偏转，导致画面呈现串黄或串紫的不均显示，参照图2至图5所示的现有技术中的显示面板在弯曲时串色分布情况示意图。有的只串黄色，有的只串蓝色，目前曲面显示面板弯曲后每片显示面板串色分布情况不固定很难达成在像素内补偿的目的。因此，有必要研究一种新的曲面显示面板及曲面显示面板的制作方法、安装有该曲面显示面板的显示装置。
本公开首先提供了一种曲面显示面板的制作方法，所述曲面显示面板包括第一基板1A和第二基板2A，所述第二基板2A包括黑矩阵24。
本公开实施例中，第一基板1A可以是阵列基板，第二基板2A可以是彩膜基板，但本公开并不限定于此。
参照图16，本公开实施例提供一种曲面显示面板的制作方法，包括：提供第一基板1A；提供第二基板2A，所述第二基板与所述第一基板相对应设置；
在所述第二基板上形成黑矩阵24，所述黑矩阵包括像素限定结构B1和补偿结构B2，每个所述补偿结构具有沿第一方向的第一宽度W1和沿第二方向的第二宽度W2，所述第一方向和所述第二方向互相垂直；
所述第一宽度与其到弯曲中心轴的距离正相关，所述弯曲中心轴的延伸方向与所述第二方向平行。
其中，获取所述补偿结构的所述第一宽度W1的方法包括：将一测试显示面板沿与显示面平行的中心轴固定，且将与所述中心轴平行的两 侧弯曲并固定；获取所述测试显示面板弯曲后的像素偏移图像；根据所述像素偏移图像模拟像素偏移信息；根据模拟的所述像素偏移信息获得所述测试显示面板的串色分布；根据所述串色分布获得黑矩阵补偿值，所述黑矩阵补偿值为所述补偿结构的所述第一宽度。
下文中将对获得黑矩阵补偿值的详细过程进行具体描述。
参照图6所示的本公开曲面显示面板的制作方法一示例实施方式的流程示意框图；该曲面显示面板的制作方法可以包括以下步骤：
步骤S10，获取所述黑矩阵24能够遮挡漏光的目标值。
步骤S20，根据所述目标值形成所述黑矩阵24。
步骤S30，在所述第一基板1A的非显示区域形成第一凹槽。
步骤S40，在所述第二基板2A的非显示区域形成第二凹槽，所述第二凹槽与所述第一凹槽相对应设置。
步骤S50，形成固定隔垫物6，所述固定隔垫物6的第一端位于所述第一凹槽内，所述固定隔垫物6的第二端位于所述第二凹槽内。
下面对曲面显示面板的制作方法的各个步骤进行详细说明。
步骤S10，获取所述黑矩阵24的目标值。
在本示例实施方式中，通过一测试显示面板3获取其黑矩阵24能够遮挡漏光的目标值。测试显示面板3为现有技术中的曲面显示面板，即弯曲后还有串色出现的曲面显示面板。参照图7所示的测试显示面板3弯曲并固定后的结构示意图，图中c表示曲面显示面板的固定中心轴位置，L1表示固定中心轴左侧第一位置，L2表示固定中心轴左侧第二位置，R1表示固定中心轴右侧第一位置，R2表示固定中心轴右侧第二位置。该测试显示面板3的具体弯曲方法为：先将测试显示面板3的背面沿与显示面平行的长度方向的固定中心轴固定在一固定轴4上，该固定轴4的厚度为大于等于1mm且小于等于1.50mm，其宽度大于等于0.8mm且小于等于1.2mm，其长度比测试显示面板3的长度至少长大约3mm。然后将该测试显示面板3放置在平坦的机台上，将该测试显示面板3的与固定轴4平行的两侧向非显示面一侧弯曲，最后可以通过透明胶带5进行固定。
当然，也可以将测试显示面板3的背面沿与显示面平行的宽度方向 中心轴固定在一固定轴4上，具体是沿宽度方向中心轴还是沿长度方向中心轴，根据实际产品的弯曲时的中心轴确定。
在本示例实施方式中，通过显微镜获取测试显示面板3弯曲后的像素偏移图像。具体为通过显微镜以及设置在目镜上的摄像头获取该测试显示面板3弯曲后的像素偏移图像，摄像头将像素偏移图像传输至一数据处理单元。数据处理单元可以为单片机、微处理器、工控机等等。参照图8所示的通过显微镜获取的图7中的测试显示面板3的像素偏移图像的示意图，从图中可以得到在固定中心轴两侧，左侧的像素向右移，右侧的像素向左移。
参照图9所示的本公开曲面显示面板的制作方法一示例实施方式的具体流程示意框图。通过显微镜获取测试显示面板3弯曲后的像素偏移图像，并将测试显示面板3的实际弯曲状态输入数据处理单元，实际弯曲状态可以包括测试显示面板3的大小、厚度、弯曲时的中心轴以及弯曲的弧度。数据处理单元根据像素偏移图像以及实际弯曲状态模拟像素偏移信息，即完成曲面显示屏弯曲模型搭建。然后数据处理单元通过Ansys软件根据像素偏移信息获得测试显示面板3的串色分布，参照图10所示的通过软件模拟的图7中的测试显示面板的串色分布情况示意图，从图中可以得到到左侧主要串红色，右侧主要串蓝色。数据处理单元通过Matlab软件根据串色分布计算获得BM补偿值；最后根据所述BM补偿值获得所述目标值。
其中，Ansys软件根据像素偏移信息获得测试显示面板3的串色分布的具体步骤可以参照相关技术，在此不再赘述。Matlab软件中具体实现如何计算获得BM补偿值也可以参照相关技术，在此也不再赘述。
目标值为基础值与BM补偿值之和，基础值为现有技术中黑矩阵24的大小值，BM补偿值为保证遮挡漏光的情况下，计算得到的黑矩阵24需要扩大的值。参照图15以及图16所示将曲面显示面板的中心位置作为坐标原点并建立直角坐标系，与固定轴4平行的坐标轴为y轴(这里假设y轴为阵列基板和彩膜基板的固定中心轴)，与固定轴4垂直的坐标轴为x轴。从图16中可以得到黑矩阵能够遮挡曲面显示面板弯曲后各个像素与x轴垂直方向上的漏光，具体可以为：黑矩阵在y轴方向上的尺 寸均没有变化，在x轴向上的尺寸有变化，而且黑矩阵的补偿位置位于靠近y轴的一侧。第二基板的黑矩阵的补偿值(BM补偿值)关于第二基板的固定中心轴(图示中的y轴)对称分布；且与第二基板的固定中心轴平行且间距相同的黑矩阵的补偿值相同，即同一列的黑矩阵的补偿值相同，也就是位于同一个横坐标值的黑矩阵在x轴向上的尺寸变化值相同；黑矩阵的补偿值从靠近第二基板的固定中心轴到远离第二基板的固定中心轴逐渐增大，即靠近y轴的黑矩阵的补偿值小于远离y轴的黑矩阵的补偿值，越远离y轴，黑矩阵的补偿值越大。
本公开实施例中，曲面显示面板可以包括相互平行的两个短边和相互平行的两个长边(例如通常的智能手机的俯视图为一个近似长方形，具有长边和短边)，其中，x轴平行于曲面显示面板的短边，y轴平行于曲面显示面板的长边，但本公开并不限定于此。
步骤S20，根据所述目标值形成所述黑矩阵。
在本示例实施方式中，先沉积黑矩阵材料层，然后根据目标值完成对黑矩阵材料层的构图工艺，使黑矩阵能够遮挡漏光。
步骤S30，在所述第一基板的非显示区域形成第一凹槽。
在本示例实施方式中，第一凹槽可以设于位于第一基板1A非显示区域B的最上层的平坦化层13，即设于第一基板1A的与密封胶层8贴合的平坦化层13。当然，在第一基板1A的非显示区域B与密封胶层8贴合的材料层不是平坦化层13而是钝化层的情况下，第一凹槽可以设于钝化层上。为了增加第一凹槽的深度，第一凹槽还可以向下延伸至下一材料层，例如，第一凹槽还可以延伸至与平坦化层13相邻的栅极绝缘层14。
参照图11所示的第一基板1A的结构示意图，第一凹槽可以包括四个第二子凹槽11以及两个第一子凹槽12。四个第二子凹槽11一一对应的设于平坦化层13四个拐角部，第二子凹槽11可以设置为直角拐角形，且第二子凹槽11的拐角与平坦化层13的拐角一致。具体而言，第二子凹槽11可以包括与平坦化层13的横边平行的第二横子凹槽以及与平坦化层13的纵边平行的第二纵子凹槽，第二横子凹槽的靠近平坦化层13的纵边一端与第二纵子凹槽的靠近平坦化层13的横边一端连通，当然， 第二纵子凹槽的深度与第二横子凹槽的深度相同。
在本示例实施方式中，第一子凹槽12可以设置为正交十字形。两个第一子凹槽12的中心点连线与第一基板1A的固定中心轴(本公开实施例中，彩膜基板和阵列基板对盒后形成曲面显示面板，因此，可以认为第一基板的固定中心轴与第二基板的固定中心轴是重合的)共线设置，第一基板的固定中心轴为第一基板1A的长度方向的中心轴。第一基板的固定中心轴与显示面平行，且在曲面显示面板弯曲时以第一基板的固定中心轴为中心轴，即与第一基板的固定中心轴平行且相对于第一基板的固定中心轴对称的两侧长边向非显示面或显示面一侧弯曲形成曲面显示面板。
在本示例实施方式中，在第一基板1A的被切割区域C也设置有第一凹槽，在外侧的两个拐角处一一对应设置有两个第二子凹槽11，在两个第二子凹槽11的中间设置有一个第一子凹槽12。如此设置能够加强第一基板1A与第二基板2A的固定效果。
另外，本领域技术人员可以理解的是，第二子凹槽11和第一子凹槽12也可以设置为同样的形状，例如均可设置为圆柱形、长方体形等形状的凹槽。
步骤S40，在所述第二基板2A的非显示区域形成第二凹槽，所述第二凹槽与所述第一凹槽相对应设置。
在本示例实施方式中，第二凹槽可以设于位于第二基板2非显示区域B的最下层的涂覆保护层23并延伸至与涂覆保护层23相邻的黑矩阵24，即设于第二基板2A的与密封胶层8贴合的涂覆保护层23以及与涂覆保护层23相邻的黑矩阵24。当然，在第二基板2的非显示区域B与密封胶层8贴合的材料层不是涂覆保护层23而是别的材料层的情况下，第一凹槽可以设于别的材料层上。将第二凹槽设于涂覆保护层23以及与涂覆保护层23相邻的黑矩阵24可以增加第二凹槽的深度。当然，第二凹槽也可以仅设于涂覆保护层23上，而不设于黑矩阵24上。
参照图12所示的第二基板2A的结构示意图，第二凹槽可以包括四个第四子凹槽21以及两个第三子凹槽22。四个第四子凹槽21一一对应的设于涂覆保护层23以及黑矩阵24的四个拐角部，第四子凹槽21可以 设置为直角拐角形，且第四子凹槽21的拐角与涂覆保护层23以及黑矩阵24的拐角一致。具体而言，非显示区域B的涂覆保护层23与黑矩阵24的形状相同，下面以涂覆保护层23为相对对象进行说明第四子凹槽21的具体结构，第四子凹槽21可以包括与涂覆保护层23的横边平行的第四横子凹槽以及与涂覆保护层23的纵边平行的第四纵子凹槽，第四横子凹槽的靠近涂覆保护层23的纵边一端与第四纵子凹槽的靠近涂覆保护层23的横边一端连通，当然，第四纵子凹槽的深度与第四横子凹槽的深度相同。四个第四子凹槽21与上述四个第二子凹槽11上下一一对应的对称设置。
在本示例实施方式中，第三子凹槽22可以设置为正交十字形。两个第三子凹槽22的中心点连线与第二基板2A的固定中心轴共线设置，第二基板的固定中心轴为第二基板2A的长度方向的中心轴。第二基板的固定中心轴与显示面平行，且在曲面显示面板弯曲时以第二基板的固定中心轴为中心轴，即与第二基板2A的固定中心轴平行，且相对于第二基板2A的固定中心轴对称的两侧长边向非显示面或显示面一侧弯曲形成曲面显示面板。第二基板2A的固定中心轴与上述第一基板1A的固定中心轴为上下平行设置。两个第三子凹槽22与上述两个第一子凹槽12上下一一对应的对称设置。
在本示例实施方式中，在第二基板2A的被切割区域C也设置有第二凹槽，在外侧的两个拐角处一一对应设置有两个第四子凹槽21，在两个第四子凹槽21的中间设置有一个第三子凹槽22。如此设置能够加强第一基板1A与第二基板2A的固定效果。
另外，本领域技术人员可以理解的是，第四子凹槽21和第三子凹槽22也可以设置为同样的形状，例如均可设置为圆柱形、正方体形的凹槽。
步骤S50，形成固定隔垫物6，所述固定隔垫物6的第一端位于所述第一凹槽内，固定隔垫物6的第二端位于所述第二凹槽内。
在本示例实施方式中，可以通过沉积方式形成固定隔垫物6，固定隔垫物6的形状与第一凹槽的形状一致，固定隔垫物6的第一端基本占满第一凹槽的容积，避免液晶流入第一凹槽，从而避免第一凹槽影响液晶的定量。固定隔垫物6的高度基本等于第一凹槽的深度、第二凹槽的 深度以及设置在第一基板1A和第二基板2A之间的液晶层7的厚度三者之和。
参照图13以及图14所示的图11中的第一基板1A与图12中的第二基板2A对盒后的结构示意图，将第二基板2A与第一基板1A对盒后，由于第一凹槽与第二凹槽对应设置，因此，固定隔垫物6的第二端伸入第二凹槽内。固定隔垫物6的第二端基本占满第二凹槽的容积，避免液晶流入第二凹槽，从而避免第二凹槽影响液晶的定量。
两个第一子凹槽12、两个第三子凹槽22以及设于其中的固定隔垫物6使曲面显示面板的中心轴固定，在后续的弯曲过程达到与测试显示面板3相同的弯曲，使曲面显示面板的串色分布情况基本一致，为在像素内补偿提供前提条件。
在本示例实施方式中，完成对盒后，可以先将被切割区域C切割掉，然后利用刚性密封胶将固定隔垫物6与第一基板1A粘接，并将固定隔垫物6与第二基板2A也粘接在一起。刚性密封胶可以形成一圈，刚性密封胶可以粘接在第二基板2A与第一基板1A之间，从而将固定隔垫物与第一基板1A和第二基板2A粘接在一起。刚性密封胶的宽度小于或等于非显示区域B的宽度，且位于靠近外侧的一圈。刚性密封胶进一步加强第二基板2A和第一基板1A的固定效果。按施工后性能分类，密封胶可以分为固化型密封胶和半固化型密封胶两种，其中固化型密封胶又可以分为刚性和柔性，刚性密封胶硫化或凝固后形成的固体，很少具有弹性，不能弯曲，通常接缝不可移动；柔性密封胶在硫化后具有弹性及柔软性。
进一步的，本公开还提供了一种利用上述曲面显示面板的制备方法制备的曲面显示面板，参照图13以及图14所示的图11中的第一基板1A与图12中的第二基板2A对盒后的结构示意图，即本公开的曲面显示面板的结构示意图，该曲面显示面板可以包括第一基板1A、第二基板2A以及固定隔垫物6。
第一基板1A可以包括显示区域AA和非显示区域B，第一基板1A的非显示区域B可以包括从下至上依次设置的下玻璃基板15、栅极绝缘层14以及平坦化层13；第一基板1A的显示区域AA可以包括从下至上 依次设置的下玻璃基板15、介电层16、栅极17、栅极绝缘层14、源漏极18、平坦化层13以及像素电极19。第二基板2A可以包括显示区域AA和非显示区域B，第二基板2A的非显示区域B可以包括从下至上依次设置的涂覆保护层23、黑矩阵24以及上玻璃基板25；第二基板2A的显示区域B可以包括从下至上依次设置的公共电极27、涂覆保护层23、像素层26以及上玻璃基板25。
黑矩阵包括像素限定结构B1和补偿结构B2，每个所述补偿结构B2具有沿第一方向(x轴方向)的第一宽度W1和沿第二方向(y轴方向)的第二宽度W2，所述第一方向和所述第二方向互相垂直；
所述第一宽度W1与所述补偿结构B2到弯曲中心轴(即图16中的y轴，也就是下文中所述的固定中心轴)的距离正相关，也就是说，离弯曲中心轴的距离越近的补偿结构的第一宽度W1越小，沿第一方向距离所述弯曲中心轴距离相等的补偿结构的第一宽度W1相同。所述沿第一方向距离所述弯曲中心轴距离指的是每个补偿结构的中心点沿第一方向到弯曲中心轴的距离。
所述第一宽度W1通过黑矩阵的基础值加补偿值来控制，表1为对图10的通过软件得到的测试显示面板串色分布情况补偿，然后计算出BM补偿值，在x(mm)为34时为中心点即图16中的x轴的0点，偏移量(shift(mm))为0,不需要进行BM补偿，在中心点的左右偏移量随着距中心点距离的加大，偏移量加大，需要补偿的值加大，第一宽度W1也越大。
表1 BM补偿值
Figure PCTCN2019097509-appb-000001
所述弯曲中心轴的延伸方向与所述第二方向平行。每个补偿结构的第二宽度W2大致相同。
在第一基板1A的非显示区域B设置有多个第一凹槽；在第二基板2A的非显示区域B设置有多个第二凹槽，第二凹槽与第一凹槽相对应设置，第二基板2A的黑矩阵24能够遮挡曲面显示面板弯曲后各个像素的漏光；固定隔垫物6设于第一基板1A与第二基板2A之间，其第一端位于第一凹槽内，其第二端位于第二凹槽内。
在本示例实施方式中，曲面显示面板还包括密封胶层8，密封胶层8粘接于固定隔垫物6与第一基板1A之间，以及固定隔垫物6与第二基板2A之间。
在本示例实施方式中，密封胶层8为刚性密封胶层。
在本示例实施方式中，第一凹槽设于第一基板1A的平坦化层13，第一凹槽可以包括两个第一子凹槽12以及四个第二子凹槽11；各个第一子凹槽12设置为正交十字形，两个第一子凹槽12的中心点连线与第一基板1A的第一基板的固定中心轴共线设置，第一基板的固定中心轴为第一基板1A的与显示面平行的弯曲时的中心轴；四个第二子凹槽11一一对应的设于平坦化层13四个拐角部，第二子凹槽11可以包括与平 坦化层13的横边平行的第二横子凹槽以及与平坦化层13的纵边平行的第二纵子凹槽，第二横子凹槽的靠近平坦化层13的纵边一端与第二纵子凹槽的靠近平坦化层13的横边一端连通。
