本申请主张在2015年11月5日在中国提交的中国专利申请号No.201510747075.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及显示技术领域，特别涉及一种显示基板、显示面板切割方法和显示装置。
背景技术
显示面板包含有两个显示基板(阵列基板和彩膜基板)，在显示面板的制造过程中，为了提高生产效率，会先制造出较大的显示基板(该显示基板包含有多个较小的子显示区域)，再将两个较大的显示基板(该两个显示基板为一块阵列基板和一块彩膜基板)通过密封胶(Sealant)粘合在一起组成原始面板，之后切割原始面板就能够一次制造出多块子显示面板。
相关技术中有一种显示基板，该显示基板上设置有带胶切割线(该带胶切割线为相邻的两个子显示区域间的切割位置，该相邻的两个子显示区域在带胶切割线侧均未设置有GOA(Gate Driver on Array，阵列基板行驱动)电路)基准点，用于确定带胶切割线的位置，在给该显示基板涂敷密封胶时，根据带胶切割线基准点确定带胶切割线的位置后，会在带胶切割线两边各设置一条与带胶切割线平行且距离相等的涂胶轨迹(涂胶喷嘴涂胶时的移动轨迹在显示基板上的投影)，密封胶从涂胶喷嘴中喷出后，会向涂胶轨迹周围流动并覆盖带胶切割线，两条涂胶轨迹产生的密封胶会在带胶切割线处产生重叠区域(即该区域有两层密封胶)。
发明人在实现本公开的过程中，发现上述方式至少存在如下缺陷：在对上述显示基板涂覆密封胶时，会由于机械误差以及涂覆密封胶时的不确定性(流体的密封胶在喷出以及在显示基板上流动时都具有不确定性)可能导致两个相邻的子显示区域上的重叠区域分布不均匀，而重叠区域过大会影响显示基板粘合后的平整性，降低产品良率。

通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是本公开的一些实施例示出的一种显示基板的结构示意图。该显示基板可以包括：
至少两个子显示区域11和至少一个阻隔单元12，子显示区域11用于形成子显示基板。
每个阻隔单元12包括：设置在显示基板上的带胶切割线13两侧的两个条状阻隔图案121和122，两个条状阻隔图案121和122分别位于两个相邻的子显示区域11的外围区域111。
图1示出的是显示基板上部分区域的示意图，其它区域类似。
综上所述，本公开的一些实施例提供的显示基板，通过在带胶切割线两边设置用于限制密封胶形状的两个条状阻隔图案，该两个条状阻隔图案避免了任一子显示区域中的重叠区域过大，解决了相关技术中会由于机械误差以及涂覆密封胶时的不确定性导致两个相邻的子显示区域上的重叠区域过大而影响显示基板粘合后的平整性的问题；达到了子显示区域上的重叠区域不会过大，产品良率较高的效果。
进一步的，请参考图2-1，其示出了本公开的一些实施例提供的另一种显示基板的结构示意图，该显示基板在图1所示的显示基板的基础上增加了更优选的部件，从而使得本公开的一些实施例提供的显示基板具有更好的性能。
可选的，任一条状阻隔图案(121或122)与带胶切割线13的距离相等，均为k。这样可以使带胶切割线13两边的密封胶的重叠区域的宽度相等，且同样为k，而带胶切割线13两边的重叠区域相等可以进一步的提高两个显示基板 粘合后制成的显示面板的平整性，提高显示面板的显示效果。
此外，显示基板上的每个子显示区域11可以包括有效显示区域和外围区域111，在显示基板上设置条状阻隔图案时，可以使条状阻隔图案距离有效显示区域较远，以避免密封胶的重叠区域距离显示区域过近而影响有效显示区域正常显示。示例性的，在图2-1中，可以使条状阻隔图案121远离其所在的子显示区域中的有效显示区域112a，以避免条状阻隔图案121距离有效显示区域112a过近，比如可以使条状阻隔图案121与有效显示区域112a的距离大于条状阻隔图案121与带胶切割线13的距离。类似的，可以使条状阻隔图案122距离其所在的子显示区域中的有效显示区域112b较远。
可选的，任一涂胶轨迹t与带胶切割线13的距离相等。涂胶轨迹与带胶切割线的距离相等有助于使密封胶在显示基板上形成相似的形状。其中，涂胶轨迹t为涂胶喷嘴涂胶时的移动轨迹在显示基板上的投影。
如图2-2所示，其为本公开的一些实施例提供的另一种显示基板的结构示意图，显示基板还包括按照每个阻隔单元对应的涂胶轨迹涂覆的两条密封胶。每个阻隔单元与位于该阻隔单元的两个条状阻隔图案之间的涂胶轨迹对应。
第一密封胶141覆盖在第一条状阻隔图案121上，且在第一条状阻隔图案121两侧均形成有密封胶图案，第一密封胶141在靠近带胶切割线13一侧的密封胶图案与两个条状阻隔图案(121和122)之间的区域形状相同，即第一密封胶141可以铺满了两个条状阻隔图案(121和122)之间的区域，第一密封胶141为两条密封胶中的任一密封胶，第一条状阻隔图案121为阻隔单元12中与第一密封胶141的涂胶轨迹t1位于带胶切割线13的同一侧的条状阻隔图案。
第二密封胶142是两条密封胶中除第一密封胶141外的另一条密封胶，第二密封胶142的涂胶轨迹为t2，第二密封胶142的形成情况与第一密封胶141相似，此外，第一密封胶141和第二密封胶142在两个条状阻隔图案121和122之间的区域的形状可以是相同的(图2-2中为了便于辨认而使两条密封胶有所区别)。
图2-2所示的显示基板中，位于带胶切割线同一侧的密封胶的涂胶轨迹与条状阻隔图案的距离较近，在此种情况密封胶在涂覆时可能有少部分越过条状阻隔图案。
需要说明的是，第一密封胶141由于涂胶轨迹距离带胶切割线13另一侧的条状阻隔图案122过远，因而在涂覆时不会越过条状阻隔图案122。第二密封胶142的情况类似，在此不再赘述。
如图2-3所示，其为本公开的一些实施例提供的另一种显示基板的结构示意图，显示基板还包括按照每个阻隔单元对应的涂胶轨迹涂覆的两条密封胶。每个阻隔单元与位于该阻隔单元的两个条状阻隔图案之间的涂胶轨迹对应。
两条密封胶(141和142)中任一密封胶的形状与阻隔单元12中两个条状阻隔图案(121和122)之间的区域形状相同(图2-3中为了便于辨认而使两条密封胶有所区别)。
图2-3示出的显示基板中，位于带胶切割线13同一侧的密封胶的涂胶轨迹t和条状阻隔图案的距离较远，在此种情况密封胶在涂覆时可能不会越过条状阻隔图案。即第一密封胶141的密封胶图案和第二密封胶142的密封胶图案均位于条状阻隔图案121和122之间。
需要说明的是，图2-3所示的显示基板中，第一密封胶141在涂覆时可能会流到条状阻隔图案121上，但未越过条状阻隔图案121到达条状阻隔图案121的另一侧。第二密封胶142的情况类似，在此不再赘述。
可选的，显示基板上任一带胶切割线均有对应的阻隔单元。即可以在第一显示基板上的每条带胶切割线上设置对应的阻隔单元，每条带胶切割线与设置在其两边的条状阻隔图案构成的阻隔单元对应。
此外，带胶切割线13可以为相邻的两个子显示区域11间的切割位置，该相邻的两个子显示区域11在带胶切割线13侧均未设置有GOA电路。可选的，带胶切割线13可以位于子显示区域11较长的一边。
可选的，本公开的一些实施例中，至少一个阻隔单元是在一次构图工艺中由光刻胶制成形成的。
可选的，任一条状阻隔图案的厚度与两条密封胶中任一密封胶的厚度相同。以图2-2示出的显示基板为例，各个区域的厚度可以具有以下关系：
两条密封胶构成的重叠区域的厚度＝条状阻隔图案121的厚度+形成于条状阻隔图案121上的第一密封胶141的厚度＝条状阻隔图案122的厚度+形成于条状阻隔图案122上的第二密封胶142的厚度。即显示基板上两个条状阻隔图案之间的区域的厚度处处相等，进一步提升了显示基板构成的显示面板的平整性， 提高显示基板的显示效果。
需要说明的是，本公开的一些实施例所涉及的各个显示基板，可以为阵列基板或彩膜基板。
需要补充说明的是，本公开的一些实施例提供的显示基板，通过使任一条状阻隔图案与带胶切割线的距离相等，这样带胶切割线两边的密封胶的重叠区域的宽度相等，达到了提高两个显示基板粘合后制成的显示面板的平整性，提高显示面板的显示效果。
需要补充说明的是，本公开的一些实施例提供的显示基板，通过使任一条状阻隔图案的厚度与两条密封胶中任一密封胶的厚度相同，达到了显示基板上两个条状阻隔图案之间的区域的厚度处处相等，进一步提升了显示基板构成的显示面板的平整性，提高显示基板的显示效果。
综上所述，本公开的一些实施例提供的显示基板，通过在带胶切割线两边设置用于限制密封胶形状的两个条状阻隔图案，该两个条状阻隔图案避免了任一子显示区域中的重叠区域过大，解决了相关技术中会由于机械误差以及涂覆密封胶时的不确定性导致两个相邻的子显示区域上的重叠区域过大而影响显示基板粘合后的平整性的问题；达到了子显示区域上的重叠区域不会过大，产品良率较高的效果。
图3是本公开的一些实施例提供的一种显示面板切割方法的流程图，其中显示面板包括第一显示基板和第二显示基板，第一显示基板包含有至少两个子显示区域和至少一个阻隔单元，子显示区域用于形成子显示基板；每个阻隔单元包括：设置在显示基板上的带胶切割线两侧的两个条状阻隔图案，两个条状阻隔图案分别位于两个相邻的子显示区域的外围区域。该显示面板切割方法包括：
在步骤301中，确定第一显示基板的带胶切割线的位置。
在步骤302中，根据带胶切割线的位置确定第一显示基板的两条涂胶轨迹，两条涂胶轨迹与带胶切割线平行且位于两个条状阻隔图案之间。
在步骤303中，根据两条涂胶轨迹涂覆密封胶。
在步骤304中，将第一显示基板与第二显示基板粘合得到显示面板。
在步骤305中，根据带胶切割线切割显示面板。
综上所述，本公开的一些实施例提供的显示面板切割方法，通过在带胶切 割线两边设置用于限制密封胶形状的两个条状阻隔图案，该两个条状阻隔图案避免了任一子显示区域中的重叠区域过大，解决了相关技术中会由于机械误差以及涂覆密封胶时的不确定性导致两个相邻的子显示区域上的重叠区域过大而影响显示基板粘合后的平整性的问题；达到了子显示区域上的重叠区域不会过大，产品良率较高的效果。
图4是本公开的一些实施例提供的另一种显示面板切割方法的流程图，其中显示面板包括第一显示基板和第二显示基板，第一显示基板包含有至少两个子显示区域，子显示区域用于形成子显示基板。该显示面板切割方法包括：
在步骤401中，确定第一显示基板的带胶切割线的位置。
在使用本公开的一些实施例提供的显示面板切割方法时，可以首先在第一显示基板上通过切割线基准点来确定带胶切割线的位置。其中切割线基准点是预先设置在第一显示基板上用于确定带胶切割线的点，而第一显示基板可以是显示面板中的任一显示基板，如阵列基板或彩膜基板。
此外，带胶切割线可以为相邻的两个子显示区域间的切割位置，该相邻的两个子显示区域在带胶切割线侧均未设置有GOA电路。
在步骤402中，在第一显示基板上形成至少一个阻隔单元。
在确定了带胶切割线后，可以根据带胶切割线的位置在第一显示基板上形成至少一个阻隔单元，其中每个阻隔单元包括：设置在显示基板上的带胶切割线两侧的两个条状阻隔图案，两个条状阻隔图案分别位于两个相邻的子显示区域的外围区域。
此外，任一条状阻隔图案与带胶切割线距离相等。这样可以使带胶切割线两边的密封胶的重叠区域的宽度(与带胶切割线垂直的方向上的宽度)相等，而带胶切割线两边的重叠区域的宽度相等可以进一步的提高第一显示基板与第二显示基板粘合后制成的显示面板的平整性，提高显示面板的显示效果。
可选的，第一显示基板上任一带胶切割线均有对应的阻隔单元。即可以在第一显示基板上的每条带胶切割线上设置对应的阻隔单元，每条带胶切割线与设置在其两边的条状阻隔图案构成的阻隔单元对应。
本步骤结束时，第一显示基板的结构可以如图2-1所示。
在步骤403中，根据带胶切割线的位置确定第一显示基板的两条涂胶轨迹，两条涂胶轨迹与带胶切割线平行且位于两个条状阻隔图案之间。
在第一显示基板上形成了阻隔单元后，可以根据带胶切割线的位置确定第一显示基板的两条涂胶轨迹，两条涂胶轨迹与带胶切割线平行且位于两个条状阻隔图案之间。
可选的，任一涂胶轨迹与带胶切割线的距离相等。涂胶轨迹与带胶切割线的距离相等有助于使密封胶在第一显示基板上形成相似的形状。
在步骤404中，根据两条涂胶轨迹涂覆密封胶。
在确定了两条涂胶轨迹之后，可以根据两条涂胶轨迹涂覆密封胶。
需要说明的是，在根据两条涂胶轨迹涂覆密封胶，可以先根据一条涂胶轨迹涂覆密封胶，再根据另一条涂胶轨迹涂覆密封胶，涂覆密封胶的过程可以参考相关技术，在此不再赘述。
本步骤结束时，第一显示基板的结构可以如图2-2所示，或者如图2-3所示。
在步骤405中，将第一显示基板与第二显示基板粘合得到显示面板。
在第一基板上涂覆两条密封胶之后，可以将第一显示基板与第二显示基板粘合得到显示面板。需要说明的是，在粘合第一显示基板和第二显示基板时，第一显示基板和第二显示基板之间还可以设置有液晶层，粘合过程可以参考相关技术，本公开实施例不再赘述。
由于第一显示基板上带胶切割线两侧的密封胶的大小均被条状阻隔图案所限制而不会过大，因而粘合而成的显示面板的平整性较高，避免了因为显示面板的不平整而造成的显示效果较差的问题。
在步骤406中，根据带胶切割线切割显示面板。
在将第一显示基板和第二显示基板粘合得到显示面板时，可以根据带胶切割线切割显示面板，将显示面板切割为多个子显示面板。之后可以对子显示面板进行后续加工工序。由于显示面板的平整性较高，因而根据带胶切割线切割显示面板得到的子显示面板的平整性也会较高。
需要补充说明的是，本公开实施例提供的显示面板切割方法，通过在形成条状阻隔图案时，使任一条状阻隔图案与带胶切割线的距离相等，这样带胶切割线两边的密封胶的重叠区域的宽度相等，达到了提高第一显示基板与第二显示基板粘合后制成的显示面板的平整性，提高显示面板的显示效果。
需要补充说明的是，本公开实施例提供的显示面板切割方法，通过在形成 条状阻隔图案时，使任一条状阻隔图案的厚度与两条密封胶中任一密封胶的厚度相同，达到了显示基板上两个条状阻隔图案之间的区域的厚度处处相等，进一步提升了显示基板构成的显示面板的平整性，提高显示基板的显示效果。
综上所述，本公开实施例提供的显示面板切割方法，通过在显示基板上形成用于限制密封胶形状的两个条状阻隔图案，该两个条状阻隔图案避免了任一子显示区域中的重叠区域过大，解决了相关技术中会由于机械误差以及涂覆密封胶时的不确定性导致两个相邻的子显示区域上的重叠区域过大而影响显示基板粘合后的平整性的问题；达到了显示面板以及将显示面板切割后得到的子显示面板的平整性较高，产品良率较高的效果。
此外，本公开的一些实施例还提供一种显示装置，该显示装置可以包括图1所示的显示基板、图2-1所示的显示基板，或者图2-2所示的显示基板，或者图2-3所示的显示基板。
以上所述仅为本公开的较佳实施例，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
