如图1和图2所示，彩膜基板的基本结构可以分为显示区域103和位于显示区域103周围的周边区域102。显示区域的黑矩阵(BM)为阵列分布，位于滤光片(如图2所示的第一滤光片104、第二滤光片105及第三滤光片106)之间，用于遮挡阵列基板上金属线造成的漏光。周边区域的遮光层102(即黑矩阵)为片状分布，因为该区域无需透光。
图3是本发明一实施例中一种显示面板的俯视结构示意图，图4是图3所示的显示面板的B-B’剖面示意图。参见图3和图4，该显示面板包括：相对设置的第一基板和第二基板，所述第一基板101的靠近第二基板的一侧上设置有遮光层102，所述遮光层102的位于周边区域的部分包括间隔设置的多个开口区域，每个开口区域内设置有透光层。
如图4所示，所述周边区域114的遮光层包括：间隔设置的多个开口区域，每个开口区域内设置有透光层107。所述透光层107与第二基板上的透光区域115至少部分重叠。
所述遮光层的材料可以为黑色树脂，所述透光层的材料可以为滤色片树脂。举例来说，遮光层和透光层的材料可以根据表1进行选择。

表1
举例来说，本实施例中的显示面板可为LCD显示面板。显示面板可以包括相对设置的阵列基板和彩膜基板，即本实施例中的第一基板为彩膜基板，第二基板为阵列基板。在彩膜基板上设置有遮光层，位于显示区域的遮光层为阵列分布，而位于周边区域的遮光层包括间隔设置的多个开口区域，并且在开口区域中形成透光层。
可理解地，如图4所示，第二基板113包括形成在第二基板上的栅线层金属111。当然除了图4中所示的结构，还可包括其他组成部分。举例来说，如依次形成于栅线层金属111上的栅绝缘层、有源层、源 极、漏极、数据线、像素电极或公共电极等等，本实施例对此不加以限定。
在此简单地描述一下盒厚测定原理。当光线通过第一基板入射到液晶单元后，直线偏振光变化为椭圆光，这是因为液晶作为各向异性物质有双折射性。通过液晶单元的光在x和y方向上发生相位偏离，相位偏离的大小取决于液晶单元之间的距离d和折射率Δn。具体关系为：Re.＝Δn·d，其中Re.为双折射相位差，d为盒厚，Δn为折射率。当该椭圆光进一步通过第二基板射出后，可通过上述公式计算得到盒厚。
本实施例在周边区域的遮光层上形成间隔设置的开口区域，并在开口区域内形成透光层107，而且该透光层107与第二基板上的透光区域115至少部分重叠。由于位于周边区域的遮光层包括透光层，使得光线能够从第一基板经过位于周边区域的遮光层中的透光层穿透液晶层并到达第二基板。
基于本实施例中显示面板的结构，通过盒厚测定原理能够测试出周边区域的盒厚分布。具体来说，根据盒厚测定原理测量位于周边区域的几个关键点的盒厚并进行比较，如果误差在预设范围内则判定周边区域的盒厚是均匀的。如果误差在预设范围之外则判定周边区域的盒厚是不均匀的，并且可以对周边区域的盒厚不均匀的位置可进行补偿，从而实现周边区域的盒厚均匀的目的。
本实施例在第一基板的周边区域的遮光层中形成间隔设置的多个开口区域，在每个开口区域内设置透光层，并且使透光层与第二基板上的透光区域至少部分重叠。基于盒厚测定原理，能够通过在周边区域中设置的多个透光层测定周边区域的盒厚分布，从而有效地判定周边区域的盒厚分布趋势，以便通过设计变更达到周边区域的盒厚均匀的目的。
在一个实施例中，透光层107与第二基板上未设置金属线的区域相对应，从而使得光线能够容易地通过透光层107达到第二基板，以便进行液晶盒的盒厚测定。
作为一种示例，如图4所示，所述透光层107与所述遮光层102交替设置。
具体来说，如图4所示，每两个透光层107之间设置有遮光层102， 即位于周边区域的透光层107与遮光层102交替设置。通过激光修复(Laser Repair)方法轰击透光层107周边的遮光层，能够使得遮光层对滤光片形成遮挡，避免具有上述结构的显示面板可能造成的亮点不良(Bright Dot Failure)。需要说明的是，该激光修复方法可以解决在周边区域设置透光层107而造成的漏光的问题，从而避免由于周边区域漏光造成的显示面板亮点不良。
在一个实施例中，设置在每个开口区域中的透光层为滤光片。
可理解地，与每个开口区域对应的滤光片的颜色可为多种预定颜色中的一种。例如，可为红色滤光片、蓝色滤光片或者绿色滤光片等等。
如图4所示，如果在每个开口区域内形成的透光层107为滤光片，则可以采用一次工艺构图同时形成位于周边区域的滤光片和位于显示区域中的同种颜色的滤光片(如图4所示的第一颜色滤光片104、第二颜色滤光片105或者第三颜色滤光片106)。例如，在第一基板101的一侧形成遮光层102后，同时刻蚀位于显示区域的透光层以及位于周边区域的透光层，形成与位于显示区域的透光层相对应的开口区域以及与位于周边区域的透光层相对应的开口区域，然后通过一次构图工艺同时在开口区域内形成颜色相同的滤光片。这样可节省工艺步骤并节约成本。
与每个开口区域对应的滤光片和与显示区域中每个子像素单元对应的滤光片的大小相等。
在本实施例中，与每个开口对应的滤光片和与显示区域中每个子像素单元对应的滤光片的大小相等，则可使得两者共用一个掩膜板，而无需制作新的掩膜板，有利于节约成本。
如图4所示，显示面板还包括：用于粘接第一基板和第二基板的封框胶110。封框胶110与第一基板和第二基板一起形成封闭的空间，并且在该封闭的空间中填充有液晶。
需要说明的是，在位于显示区域周围的周边区域的不同位置处的遮光层上均设置有透光层。举例来说，如图3所示，不仅可在左侧的周边区域的不同位置处设置多个透光层，还可以在上侧、右侧及下侧的周边区域的不同位置处设置透光层。这样可以检测周边区域的不同位置处的盒厚，以便对周边区域的盒厚分布进行更为全面的监测。
如图4所示，第一基板还包括：设置在第一基板一侧上的彩膜滤光层、设置在所述彩膜滤光层背离所述第一基板的一侧上的保护层108以及设置在所述保护层108背离所述彩膜滤光层的一侧上的隔垫物109。相应地，在第二基板上与隔垫物109相对应的位置处也可以设置有隔垫物支撑柱112(Photo Spacer Pillow)
具体来说，彩色滤光层包括在显示区域重复排列的第一颜色滤光片104、第二颜色滤光片105和第三颜色滤光片106。保护层108用于对透光层107以及彩色滤光片104、105、106形成保护。设置在第一基板上的隔垫物109以及设置在第二基板上的隔垫物支撑柱112用于支撑液晶盒厚。
在一个实施例中，提供了一种显示面板的盒厚测试方法。该显示面板包括相对设置的第一基板和第二基板，所述第一基板的靠近所述第二基板的一侧上设置有遮光层，所述遮光层包括位于显示区域的遮光层以及位于处于显示区域周围的周边区域的遮光层。图5示出了一种显示面板的盒厚测试方法的方法步骤流程示意图，该方法包括：
步骤S1：对所述位于周边区域的遮光层进行刻蚀，形成间隔设置的多个开口区域；每个开口区域与所述第二基板上的透光区域至少部分重叠。
具体来说，可采用光刻的方式对位于周边区域的遮光层进行刻蚀，以形成间隔设置的多个开口区域，而且使得每个开口区域与第二基板上的透光区域至少部分重叠，以便通过该开口区域进行盒厚测定。
步骤S2：在所述多个开口区域中的每个开口区域中形成透光层。
具体来说，在遮光层背离基板的一侧涂覆透光材料层，并对透光材料层进行光刻，以便在处于周边区域的开口区域中形成透光层。
步骤S3：采用盒厚测定设备，通过所述透光层检测所述周边区域的盒厚分布。
在本实施例中，在第一基板的位于周边区域的遮光层上形成间隔设置的多个开口区域，在每个开口区域内设置透光层，并且使得透光层与第二基板上的透光区域至少部分重叠。基于盒厚测定原理，通过设置在周边区域的多个透光层测定周边区域的不同位置处的盒厚分布，从而有效地判定周边区域的不同位置处的盒厚分布趋势，以便通过设计变更达到使得周边区域的盒厚均匀的目的。
如图6所示，在步骤S3之后，还可以包括如下步骤：
步骤S4：采用激光修复方法，利用激光轰击所述透光层周边的遮光层，以使所述遮光层对所述透光层形成遮挡。
具体来说，如图7所示，使用激光修复方法，采用激光轰击透光层107周边的遮光层，以使所述遮光层对所述透光层107形成遮挡，如图8所示。这样，在盒厚测试完成后，采用激光修复方法使得透光层被遮光层覆盖起来，从而能够避免由于透光层107的引入而导致的亮点不良。
具体地，在遮光层102被激光照射的部分，设置在遮光层102表面上的保护层108首先挥发掉，接着，暴露的遮光层102挥发产生的粉墨附着到透光层107下方的保护层108上。
如图8所示，修复后的显示面板的遮光层在位于周边区域的部分包括间隔开设置的多个第一遮光部分121(原来的遮光层102)，相邻的两个第一遮光部分121由第二遮光部分122连接。第二遮光部分122与第二基板上的透光区域115至少部分重叠。在图8示出的实施例中，第二遮光部分122是透光子层201(原来的透光层107)、保护层108的残部和遮光子层202的三层叠层结构，其中，遮光子层202与第一遮光部分121的材料相同。从图8可以看出，由于原来的遮光层102在激光修复过程中有一部分颗粒挥发掉了，第一遮光部分121的厚度小于透光子层201(原来的透光层107)的厚度。
需要说明的是，尽管图7中的透光层和遮光层上覆盖有保护层108，但这并不是必需的。在这种情况下，在修复后的显示面板中，第二遮光部分122是透光子层201(原来的透光层107)、和遮光子层202的双层叠层结构，其中，遮光子层202与第一遮光部分121的材料相同。
在一个实施例中，所述透光层与所述第二基板上未设置金属线的区域相对应。这样使得光能够更容易地经透光层通过第二基板，以便进行液晶盒的盒厚测定。
在一个实施例中，在所述多个开口区域中的每个开口区域中形成透光层包括：
在所述多个开口区域中的每个开口区域中形成滤光片。
可理解地，与每个开口区域对应的滤光片的颜色可以为多种预定颜色中的一种。例如，可以为红色滤光片、蓝色滤光片或者绿色滤光 片等等。
在本实施例中，如果在每个开口区域内形成的透光层为滤光片，则可以采用一次工艺构图同时形成位于周边区域的滤光片和位于显示区域中的具有同种颜色的滤光片。例如，在基板的一侧形成遮光层后，对位于显示区域的遮光层以及位于周边区域的遮光层同时进行刻蚀，以便形成开口区域。进一步地，通过一次构图工艺同时在开口区域内形成颜色相同的滤光片。如此，可节省工艺步骤并节约成本。
上述实施例提供的显示面板的盒厚测试方法不仅可以在设计阶段为设计提供数据依据，还可以在制造阶段实时监控产品的周边区域的盒厚状况，从而在制造阶段对产品可能发生的周边区域不良(诸如周边区域发黄)做出预判，避免可能产生的不良率和成本损失。举例来说，对于周边区域的盒厚分布不均匀的显示面板，在切割工艺之后可不再进行模组制作，或进行降级处理。此方法可在一定程度上降低材料浪费，且有助于产品的分类管理。
上述任意一种显示面板以及任意一种显示面板的盒厚测试方法，都可以适用于各类TFT-LCD制造工艺，例如TN、ADS、VA、IPS。
本发明的一个实施例提供了一种显示装置，包括：上述任意一种显示面板。该显示装置可以为：液晶显示面板、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。由于该显示装置包括上述任意一种显示面板，因而可以解决同样的技术问题，并取得相同的技术效果。
