柔性OLED显示面板的母板结构以及切割方法 技术领域
本申请涉及显示技术领域，具体涉及一种柔性OLED显示面板的母板结构以及切割方法。
 背景技术
目前，在制造成包括多个显示面板的未切割的显示面板后，通常需要通过激光倒角切割机来切割该未切割的显示面板。其中，在激光切割之前，会在该未切割的显示面板上贴合上一支撑板，并在支撑板的另一面上贴上一保护膜。激光切割时，会产生大量的灰烬，这些灰烬会残留在支撑板和显示面板上，由于保护膜和显示面板之间会形成一空切层，因此激光倒角切割机自带的集尘系统无法将这些灰烬抽出，这些无法抽出的灰烬，会污染显示面板，并且影响后续盖板贴合的成功率，进而使得产品良率降低。

在一些实施例中，支撑基板10包括相对设置的第一端部101和第二端部102，以及相对设置的第三端部103和第四端部104。请参阅图2，图2为本申请所提供的柔性OLED显示面板的母板结构的第二种实施方式的结构示意图。
在支撑基板10上设置有多个第一端部101、多个第二端部102、多个第三端部103以及多个第四端部104。其中，多个切割槽201沿着第一端部101、第二端部102、第三端部103和第四端部104设置。
在切割时，激光倒角切割机根据切割槽201的位置对该柔性OLED显示面板的母板结构100进行切割。由于在第一端部101、第二端部102、第三端部103和第四端部104上设置有切割槽201。在切割槽201的位置上，将不存在激光切割制程基板10所产生的灰烬，并且切割过程中激光与柔性OLED显示面板的母板结构100产生的灰烬可以轻易地被激光倒角切割机中集尘系统抽出。因此提高了显示面板表面的洁净程度，并且提高后盖板与显示面板贴合的成功率，进而提高了产品良率。
在第一端部101、第二端部102、第三端部103或第四端部104上，多个切割槽201相互间隔排布。
请继续参阅图2，设置在第一端部101的切割槽201与设置在第二端部102的切割槽201相互对称。设置在第三端部103的切割槽201与设置在第四端部104的切割槽201相互对称。
设置在第一端部101的切割槽201的长度和设置在第二端部102的切割槽201的长度小于第一间距。第一间距为第一端部101与第二端部102之间的距离。设置在第三端部103的切割槽201的长度和设置在第四端部104的切割槽201的长度小于第二间距，第二间距为第三端部与第四端部之间的距离。
即，第一端部101的切割槽201与第二端部102的切割槽201之间还存在有部分支撑基板10。第三端部103的切割槽201与第四端部104的切割槽201之间还存在有部分支撑基板10，在制作支撑基板10的制程时。即可一并制作位于第一端部101、第二端部102、第三端部103和第四端部104上的切割槽201，因此缩减了工艺制程所需的时间，提高了工作效率。
在本申请另一些实施例中，多个切割槽201在支撑基板10上呈阵列排布。请参阅图3，图3为本申请所提供的柔性OLED显示面板的母板结构的第三种实施方式的结构示意图。
具体的，该多个切割槽201可以为同一种规格尺寸，并且在该支撑基板10的支撑面20上呈规则的阵列排布。这样可以降低工艺难度。此外，由于该多个切割槽201呈阵列排布在支撑基板10上。因此，不仅便于对柔性OLED显示面板的母板结构进行切割。同时，还能够保证切割过程中产生的灰烬能够被激光倒角切割设备中的集尘系统抽出，从而提高了柔性OLED显示面板表面的洁净度。
进一步的，请参阅图4，图4为本申请所提供的柔性OLED显示面板的母板结构的第四种实施方式的结构示意图。OLED显示面板20的一侧对应至少两个切割槽201。其中，OLED显示面板20的一侧可以对应两个切割槽201，如图4所示。当然，OLED显示面板20的一侧可以对应三个切割槽201，或者OLED显示面板20的一侧可以对应多个凹槽201。在本实施例中，仅仅以两个切割槽201为例进行说明。
可选的，请参阅图5，图5为本申请所提供的柔性OLED显示面板的母板结构的第五种实施方式的结构示意图。支撑基板10包括相对设置的第一端部101和第二端部102，以及相对设置的第三端部103和第四端部104。本实施例中第一端部101、第二端部102、第三端部103以及第四端部104的设置方法与前面实施例的类似，在此不再赘述。而本实例与前面实施例的区别在于：
多个切割槽201包括多个第一切割槽2011和多个第二切割槽2012。其中，第一切割槽2011从第一端部101延伸至第二端部102，第二切割槽2012从第三端部103延伸至第四端部104。
例如，多个第一切割槽2011从第一端部101延伸至第二端部102，并间隔设置在该支撑基板10的支撑面20上。多个第一切割槽2011的形状、大小均一致。在本实施例中，由于在支撑基板10上间隔设置有多个第一切割槽2011，并且该多个第一切割槽2011从第一端部101延伸至第二端部102，因此能够进一步地提高显示面板30表面的洁净程度，并且提高后盖板与显示面板30贴合的成功率，进而提高了产品良率。另外，由于该多个第一切割槽2011从第一端部101延伸至第二端部102。因此，切割过程中产生的灰烬更容易被激光倒角切割设备中的集尘系统抽出。因此，相对于前面实施例来说，本实施例的方案进一步的提高了产品良率。需要说明的是，第二切割槽2012的设置方法与第一切割槽2011的设置方法类似，具体请参阅第一切割槽2011的设置方法，在此不再赘述。
切割槽201的深度小于支撑基板10的厚度。
在本实施例中，为了抽出切割过程中产生的灰烬，通过在支撑面20上设置多个切割槽201，且每个切割槽201均位于相邻柔性OLED显示面板30之间，切割完成后，可以抽出切割过程中产生的灰烬。因此提高了显示面板30表面的洁净程度，并且提高后盖板与显示面板30贴合的成功率，进而提高了产品良率。
请参阅图6，图6为本申请实施例提供的切割方法的流程示意图。
一种切割方法，包括：
301、提供一柔性OLED显示面板的母板结构。
302、将柔性OLED显示面板的母板结构贴合至预先制成的支撑基板的支撑面上。
303、切割柔性OLED显示面板的母板结构，得到单片的柔性OLED显示面板。
其中，在步骤301中，该柔性OLED显示面板的母板结构可参照以上图1、图2、图3、图4或图5所示。
本申请提供的柔性OLED显示面板的母板结构以及切割方法，通过在支撑面上设置多个切割槽，且每个切割槽均位于相邻柔性OLED显示面板之间。切割完成后，可以抽出切割过程中产生的灰烬。因此提高了显示面板表面的洁净程度，并且提高后盖板与显示面板贴合的成功率，进而提高了产品良率。
以上对本申请实施例提供的柔性OLED显示面板的母板结构以及切割方法进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
