相关申请的交叉引用
本申请主张在2016年1月29日在中国提交的中国专利申请号No.201610065507.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及显示领域，特别是指一种显示基板、显示装置及定位标识的识别方法。
背景技术
在当前显示装置的制作过程中，显示基板的上、下两侧都需要分别设置定位标记，以进行研磨、检查、贴Pol等工艺。由于相关技术中的标记Mark需要在空白区域进行设计，那么，在Panel加装背光源后，Mark所在的空白区域势必会有漏光情况发生。而为了防止漏光，那么必须在后期对该区域进行处理，从而导致工艺变得复杂、成本提升、且产品品质不高。
此外，在基板上为Mark预留空白区域，也不符合显示装置向窄边框甚至无边框发展的趋势。
发明内容
本公开的目的是提供一种定位标识的设置方案，不需要对定位标识的设置区域进行防漏光处理，可提高显示装置制作效率，进而降低生产成本。
为实现上述发明目的，一方面，本公开的实施例提供一种显示基板，包括：在衬底基板第一侧面上形成的第一图形和第二图形，所述第二图形设置在所述第一图形与衬底基板之间，且所述第一图形具有一正对所述第二图形的第一通孔；其中，所述第一图形与所述第二图形由反光率不同的材料形成；所述第一通孔作为在对衬底基板第一侧面一侧的定位标识，用于定位所述衬底基板的第一侧面。

可选地，所述第一图形为所述显示基板的金属图形，所述第二图形为所述显示基板的黑矩阵；或者第一图形为所述显示基板的黑矩阵，所述第二图形为所述显示基板的金属图形。
可选地，所述第一通孔为四个，分布成一矩形的四个顶点；和/或所述第二通孔为四个，分布成另一矩形的四个顶点。
可选地，所述第一通孔和所述第二通孔的图形为圆形或多边形。
可选地，所述第一通孔和所述第二通孔设置在非显示区域内。
可选地，第一图形为吸光材料形成、第二图形为反光材料形成；或者第一图形为反光材料形成、第二图形为吸光材料形成。
另一方面，本公开还提供一种显示装置，包括有上述显示基板。
此外，本公开还提供一种定位标识的识别方法，应用于上述显示基板，包括：对所述衬底基板的第一侧面进行照射；根据所述基板的第一侧面的反射光，确定出由所述第一通孔作为的定位标识，用于定位所述衬底基板的第一侧面。
可选地，所述基板的第二图形具有一正对第一图形的第二通孔，所述第二通孔位于所述衬底基板第一侧面的正向投影与所述第一通孔位于所述衬底基板第一侧面的正向投影相互错开；所述方法还包括：对所述衬底基板的第二侧面进行照射，所述第二侧面为所述衬底基板上与所述第一侧面相对的一侧；根据所述基板的第二侧面的反射光，确定出由所述第二通孔作为的第二定位标识，用于定位所述衬底基板的第一侧面。
本公开的上述技术方案的有益效果如下：在本公开的方案中，利用相互重叠、且反光能力不同的两个图形，制作出可通过反射光识别的定位标识。由于不需要设置在显示基板的透明区域上，因此不需要对定位标识的设置区域进行漏光处理，可提高显示装置制作效率，进而降低生产成本。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
图1所示的是一种显示装置的基板，其中，需要在基板边缘的空白区域设计定位标识Mark(即图1中黑色十字图形)。其中，基板的空白区域是上下透光的，因此可以作为基板上侧或下侧的对位标记。由于Mark需要在空白区域进行设计，那么，在Panel加装背光源后，Mark所在的空白区域势必会有漏光情况发生。而为了防止漏光，那么必须在后期对该区域进行处理，从而导致工艺变得复杂、成本提升、且产品品质不高。此外，在基板上为Mark预留空白区域，也不符合显示装置向窄边框甚至无边框发展的趋势。
针对相关技术存在的问题，本公开提供一种新的定位标识的设计方案， 不需要设置在基板的空白区域上，从而不需要再使用额外工艺对空白区域进行防漏光处理。
一方面，本公开的实施例提供一种显示基板，如图2所示，包括：在衬底基板1的第一侧面(即图2中衬底基板1的上侧)上形成的第一图形A和第二图形B，该第二图形B设置在第一图形A与衬底基板1之间。其中，第一图形A具有一正对第二图形B的第一通孔Mark1。在本实施例中，第一图形A和第二图形B由反光率不同的材料形成，通过反射光检测的方法可以准确地识别出第一通孔Mark1的位置，因此将该第一通孔Mark1用作对衬底基板1的第一侧面进行切割、掩膜、检查、贴pol等工艺时所使用的定位标识。
作为示例性介绍，假设第一图形A为吸光材料形成、第二图形B为反光材料形成，可以理解的是，反光材料的反光率通常要大于吸光材料的反光率。在对衬底基板1的第一侧面进行定位时，只需要对衬底基板1的第一侧面进行照射。参考图3，显然光线打到第一通孔产生的反射光的强度，要大于光线打到第一图形A上产生反射光的强度。以第一通孔为十字形作为示例性介绍(第一通孔也可以是圆形或其他多边形)，参考图4，通过反射光的识别方法，最终会在基板上确定出比周边亮度高的十字标记，该十字标记即为作为定位标识的第一通孔。
同理，若第一图形A为反光材料形成、第二图形B为吸光材料形成，则最终会识别出比周边亮度低的十字标记，本文不再赘述。
可见，在本实施例的基板中，定位标识不需要设置在基板完全透光的区域上，因此不需要使用额外的制作工艺对透光区域进行防漏光处理，从而减小阵列基板的制作工序，进而降低生产成本。
当然，也可以采用本公开的方法设置衬底基板1位于第二侧面(即图2中衬底基板1的下侧，是衬底基板上与第一侧面相对的一侧)的定位标识。即在上述图2的基础之上，本实施例的第二图形B具有一正对第一图形A的第二通孔Mark2。该第二通孔Mark2位于衬底基板1第一侧面的正向投影与第一通孔Mark1位于所述衬底基板1第一侧面的正向投影相互错开，作为衬底基板1第二侧面一侧的定位标识。
示例地，还是以第一图形A为吸光材料形成、第二图形B为反光材料形 成为例，在对衬底基板1的第二侧面识别定定位标识时，只需要对衬底基板1的第二侧面进行照射。参考图5，显然照射的光线打到第二通孔产生的反射光的强度，要小于光线打到第二图形A上产生反射光的强度。以第二通孔为十字形作为示例性介绍(第二通孔也可以是圆形或其他多边形)，参考图6，通过反射光的识别方法，最终在基板第二侧面上确定出比周边亮度低的十字标记，该低亮度的十字标记即为第二通孔，作为对衬底基板1第二侧面进行定位时所使用的定位标识。
通过对比可以知道，相关技术中的定位标识由一个材料层形成，且需要设置在显示基板单独的一个透明区域上，而本公开的定位标识由两个反光率不同的材料层共同形成，且不需要设置在透明区域上。
此外，为了不添加额外的制作工艺，本公开可以使用显示基板上的现有图形的制作工艺，制作第一图形以及第二图形。
在相关技术中的显示装置中，基板上的黑矩阵与金属图形(金属图形一般是指数据线、扫描线等)在对光线的反射率或吸收率上存在明显差异。因此，在本实施例的第一图形和第二图形中，其中一者可以与显示装置的黑矩阵在一个构图工艺中，同层同材料形成；另一者则可以与显示装置的金属图形(金属图形一般是指基板上的信号线)在一个构图工艺中，同层同材料形成。
通过上述方案可以知道，本实施例的显示基板的第一图形和第二图形可以与现有的其它功能图形复用一个构图工艺，因此不会额外增加显示基板的图层结构，也不会增加显示基板的制作工序。
进一步地，在具体的显示基板中，本实施例的第一图形以及第二图形可以就是指显示基板上的黑矩阵和金属图案，复用原有图形作为定位标识，可以避免额外占用显示基板的空间，因此符合当前窄边框或者无边框显示器的发展趋势。
此外，本实施例的第一通孔和第二通孔作为定位标识可以为多个。作为可选方案参考图4和图5所示，第一通孔Mark1和/或第二通孔Mark2为四个。作为示例性介绍，四个第一通孔分布成一矩形的四个顶点，四个第二通孔分布成另一矩形的四个顶点。通过显示基板每侧的四个定位标识，可以准确地 完成竖直方向以及水平方向上的定位。
以上即为本实施例所提供的显示基板，相比相关技术，具有以下有益效果：
1)基板不用再设置透明区域，因此不需要再进行防漏光处理；
2)定位标识与基板既有图形复用一个构图工艺制作，因此不额外添加制作成本；
3)用于形成定位标识的第一图形和第二图形即基板现有的黑矩阵和金属图形，因此不会额外占用显示基板横向上的空间，符合当前显示装置向窄边或无边方向的发展趋势。
另一方面，本公开的实施例还提供一种定位标识的识别方法，适用于上述显示基板。
基于该显示基板，本实施例在识别衬底基板第一侧面上的定位标识的流程包括：
步骤一，对衬底基板的第一侧面进行照射；
步骤二，根据衬底基板的第一侧面的反射光，确定出由所述第一通孔作为的该衬底基板第一侧面一侧的定位标识，该定位标识用于定位所述衬底基板的第一侧面。
同理，本实施例在识别衬底基板第二侧面上的定位标识的流程包括：
步骤三，对衬底基板的第二侧面进行照射。
步骤四，根据基板的第二侧面的反射光，确定出由第二通孔作为的该衬底基板第二侧面一侧的定位标识，该定位标识用于定位所述衬底基板的第二侧面。
基于上述描述可以知道，本实施例通过反射光检测方法，即可识别出上述显示基板上所设置的定位标识，由于方案简单且易于实施，因此具有很高的实用价值。
此外，本实施例还提供一种包括上述显示基板的显示装置。作为实施例介绍，如图7所示，本实施例的显示装置由对盒成形的彩膜基板72和阵列基板71组成。其中，该阵列基板71即上文所述的显示基板，在其上方形成有黑矩阵A和金属图形B。黑矩阵A具有正对金属图形B的第一通孔Mark1， 该第一通孔Mark1作为在彩膜基板上方的定位标识。在对彩膜基板的上侧面对进行切割、掩膜、设置偏光片时，可根据该第一通孔Mark1完成相关定位。金属图形B具有对应黑矩阵A的第二通孔Mark2，该第二通孔Mark2作为在阵列基板71下方的定位标识。同理，在对阵列基板下方进行切割、掩膜时，可根据该第二通孔Mark2完成相关定位。
在本实施例中，利用金属图形和黑矩阵的反光率，制作出能够通过反射光进行识别的定位标识，由于不用设置在显示基板的透明区域上，因此不需要对定位标识的设置区域进行防漏光处理，可提高显示装置制作效率，进而降低生产成本。
这里需要给予说明的是，图7所示的结构仅用于示例性介绍，本公开的黑矩阵可以设置在金属图形下方。此外，本实施例中，金属图形与黑矩阵并不一定形成在一个显示基板上，例如黑矩阵可以形成在显示装置的彩膜基板上，而金属图形可以形成在显示装置的阵列基板上。
以上所述是本公开的可选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
