 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。另外，本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。
请参阅图1a，图1a为第一种外形差不多的OLED显示面板的结构示意图。如图1a所示，OLED显示面板10a、OLED显示面板20a以及OLED显示面板30a为外形差不多的显示面板。其中，OLED显示面板10a为在显示区域内进行打孔的显示面板；OLED显示面板20a以及OLED显示面30a为在显示区域的边缘进行打孔的显示面板。请参阅图1b，图1b为第二种外形差不多的OLED显示面板的结构示意图。如图1b所示，OLED显示面板10b以及OLED显示面板20b为外形差不多的显示面板。其中，OLED显示面板10b与OLED显示面板20b在显示区域的边缘有差异。
结合图1a、图1b所示，为了高效的利用掩膜板以降低成本，可以将外形差不多的OLED显示面板共用一种掩膜板。然而，由于OLED显示面板在显示区域边缘处的膜层厚度不一致，进行外形修剪切割时容易产生裂缝，进而影响OLED显示面板的封装效果。
基于此，本申请提供一种显示面板，包括基板，基板包括显示区域以及设置在显示区域外的非显示区域，非显示区域上设置有第一凹槽；有机发光材料层，有机发光材料层设置在基板上，且有机发光材料层在第一凹槽处断开；以及封装层，封装层设置在有机发光材料层上，且封装层在第一凹槽处断开。
本申请提供的OLED显示面板，由于在非显示区域设置有第一凹槽，且有机发光材料层以及封装层均在第一凹槽处断开，从而在进行外形修剪切割时可以截断切割裂纹；也即，在外形差不多的OLED显示面板共用一种掩膜板的同时，通过在需要进行外形修剪的区域设置第一凹槽可以避免切割时产生裂缝朝向显示区域延伸，进而提高了OLED显示面板的封装效果。
请参阅图2，图2为本申请实施例提供的OLED显示面板的整体结构示意图。如图2所示，本申请实施例提供的OLED显示面板100包括依次层叠设置的基板1、阳极、发光材料层20、阴极以及封装层30。其中，基板1包括依次层叠设置的基底10、晶体管层11。晶体管层11包括依次层叠设置的第一绝缘层105、有源层、第二绝缘层106、栅极、第三绝缘层107、源极/漏极、第四绝缘层108。也即，绝缘层101包括依次层叠设置的第一绝缘层105、第二绝缘层106、第三绝缘层107、第四绝缘层108。
具体的，请参阅图3，图3为本申请实施例提供的OLED显示面板的第一种结构示意图。如图3所示，本申请实施例提供的OLED显示面板100包括基底10、有机发光材料层20以及封装层30。其中，基底10包括显示区域11以及设置在显示区域11外的非显示区域12。非显示区域12上设置有第一凹槽40。有机发光材料层20设置在基底10上，且有机发光材料层20在第一凹槽40处断开。封装层30设置在有机发光材料20层上，且封装层30在第一凹槽40处断开。
需要说明的是，有机发光材料层20以及封装层30均对应设置在显示区域11上，并延伸至非显示区域12。也即，在本申请实施例中，在显示区域11以及非显示区域12上均设置有有机发光材料层20以及封装层30。
具体的，基底10可以是刚性基底或柔性基底。刚性基底可以是玻璃基底等。柔性基底可以是具有单层或多层柔性基底膜的结构，柔性基底可以采用聚酰亚胺、聚对苯二甲酸乙二酯、聚萘二甲酸丁二醇或聚碳酸酯等柔性基底材料，也可以是金属箔等材料。

具体的，有机发光材料层20可以包括针对发光像素设置的红色有机发光材料、绿色有机发光材料或者蓝色有机发光材料，还可以包括整面铺设的公共功能层材料（例如：电子传输材料、空穴阻挡材料、空穴传输材料、电子阻挡材料等），本实施例中，公共功能层材料在第一凹槽40断开、在第二凹槽60处也断开。封装层30包括交替叠置的至少一层有机层和至少一层无机层（例如无机层、有机层、无机层三层堆叠结构），设置有机层和无机层将外界多数水分进行阻隔，同时对封装层起到平整作用，提高了封装层的封装效果。
进一步的，请参阅图4，图4为图3所示的OLED显示面板的基板的结构示意图。如图4所示，第一基底102上设置有第一子凹槽41。绝缘层101上设置有第一通孔42。第一子凹槽41与第一通孔42对应设置形成第一凹槽40。可以理解的，第一子凹槽41的开口大于第一通孔42的开口。也即，第一凹槽40的内轮廓形状为凸型。
其中，绝缘层101包括第一延伸部1011。第一延伸部1011设置在第一子凹槽41的正上方，且第一延伸部1011的长度L1与第一子凹槽41的深度H1的比值大于1。第一子凹槽41的底壁与第一子凹槽41的侧壁之间的夹角为直角。具体的，第一通孔42的两侧均设置有第一延伸部1011，且位于第一通孔42两侧的第一延伸部1011对称设置。
结合图3、图4所示，由于设置有第一凹槽40使得有机发光材料层20以及封装层30从显示区域11延伸至非显示区域12时，有机发光材料层20以及封装层30在第一凹槽处40断开，从而在进行外形修剪切割时可以截断切割裂纹。
请参阅图5,图6，图5为本申请实施例提供的OLED显示面板的第二种结构示意图。图6为图5所示的OLED显示面板的基板的结构示意图。其中，图5、图6所示的OLED显示面板100与图3所示的OLED显示面板100的区别在于：在图3所示的OLED显示面板100中，第一子凹槽41的底壁与第一子凹槽41的侧壁之间的夹角Q1为直角；在图5、图6所示的OLED显示面板100中，第一子凹槽41的底壁与第一子凹槽41侧壁之间的夹角Q1为锐角。
如图6所示，第一基底102上设置有第一子凹槽41。绝缘层101上设置有第一通孔42。第一子凹槽41与第一通42对应设置形成第一凹槽40。可以理解的，第一通孔42的侧壁与第一子凹槽41的底壁之间的夹角等于第一子凹槽41的侧壁与第一子凹槽41的底壁之间的夹角。
结合图5、图6所示，由于设置有第一凹槽40使得有机发光材料层20以及封装层30显示区域11延伸至非显示区域12，有机发光材料层20以及封装层30在第一凹槽40处断开，从而在进行外形修剪切割时可以截断切割裂纹。
请参阅图7、图8，图7为本申请实施例提供的OLED显示面板的第三种结构示意图。图8为图7所示的OLED显示面板的基板的结构示意图。其中，图7、图8所示的OLED显示面板100与图3所示的OLED显示面板100的区别在于：在图7、图8所示的OLED显示面板100中，第一子凹槽41的底壁上设置有第三子凹槽50，且第三子凹槽50的开口小于第一子凹槽40的开口。
如图8所示，第一基底102上设置有第一子凹槽41。绝缘层101上设置有第一通孔42。第一子凹槽41与第一通孔42对应设置形成第一凹槽40。其中，第一子凹槽41的底壁上设置有第三子凹槽50，且第三子凹槽50的开口小于第一子凹槽40开口。
结合图7、图8所示，由于设置有第一凹槽40使得有机发光材料层20以及封装层30显示区域11延伸至非显示区域12时，有机发光材料层20以及封装层30在第一凹槽40处断开，从而在进行外形修剪切割时可以截断切割裂纹。
请参阅图9，图9为本申请实施例提供的OLED显示面板的第四种结构示意图。其中，图9所示的OLED显示面板100与图3所示的OLED显示面板100的区别在于：在图9所示的OLED显示面板100中，显示区域11内设置有开口，开口的周缘设置有第二凹槽60；第二凹槽60设置在显示区域11与第一凹槽40之间；有机发光材料层20在第二凹槽处60断开，封装层30在第二凹槽60处连续。
第一方面，本申请提供的OLED显示面板100，由于在非显示区域12设置有第一凹槽40，且有机发光材料层20以及封装层30均在第一凹槽40处断开，从而在进行外形修剪切割时可以截断切割裂纹；也即，在外形差不多的OLED显示面板共用一种掩膜板的同时，通过在需要进行外形修剪的区域设置第一凹槽可以避免切割时产生裂缝朝向显示区域延伸，进而提高了OLED显示面板的封装效果。
第二方面，本申请提供的OLED显示面板100，在显示区域11与第一凹槽40之间还设置有第二凹槽60，且有机发光材料层20在第二凹槽60处断开，封装层30在第二凹槽60处连续，从而可以保证OLED显示面板的侧向封装效果。
具体的，请参阅图10，图10为图9所示的OLED显示面板的基板的结构示意图。如图10所示，第一基底102上设置有第一子凹槽41和第二子凹槽61。绝缘层101上设置有第一通孔42和第二通孔62。第一子凹槽41与第一通孔42设置形成第一凹槽40。第二子凹槽61与第二通62对应设置形成第二凹槽60。可以理解的，第一子凹槽41的开口大于第一通孔42的开口。第二子凹槽61的开口大于第二通孔62的开口。也即，第一凹槽40的内轮廓形状为凸型。第二凹槽60的内轮廓形状为凸型。
其中，绝缘层101包括第一延伸部1011。第一延伸部1011设置在第一子凹槽41的正上方，且第一延伸部1011的长度L1与第一子凹槽41的深度H1的比值大于1。第一子凹槽41的底壁与第一子凹槽41的侧壁之间的夹角Q1为直角。具体的，第一通孔42的两侧均设置有第一延伸部1011，且位于第一通孔42两侧的第一延伸部1011对称设置。
其中，绝缘层101包括第二延伸部1012。第二延伸部1012设置在第二子凹槽61正上方，且第二延伸部1012的长度L2与第二子凹槽61的深度H2的比值介于0.3-0.4。第二延伸部1012与第二子凹槽61的侧壁之间的夹角Q2介于75度至180度之间。具体的，第二通孔62的两侧均设置有第二延伸部1012，且位于第二通孔62两侧的第二延伸部1012对称设置。
在一种实施方式中，第二延伸部1012的长度L2与第二子凹槽61的深度H2的比值可以为0.33。在另一种实施方式中，第二延伸部1012的长度L2与第二子凹槽61的H2的比值可以为0.39。在再一实施方式中，第二延伸部1012的长度L2与第二子凹槽61的深度H2的比值可以为0.36。具体的，第二延伸部1012的长度L2为1微米，第二子凹槽61的深度H2为3微米。
在一种实施方式中，第二延伸部1012与第二子凹槽61的侧壁之间的夹角Q2可以为80度。在另一种实施方式中，第二延伸部1012与第二子凹槽61的侧壁之间的夹角Q2可以为120度。在再一种实施方式中，第二延伸部1012与第二子凹槽61的侧壁之间的夹角Q2可以为160度。
结合图9、图10所示，由于设置有第一子凹槽41使得有机发光材料层20以及封装层30从显示区域11延伸至非显示区域12时，有机发光材料层20以及封装层30在第一凹槽处40断开，从而在进行外形修剪切割时可以截断切割裂纹。由于设置有第二凹槽60使得有机发光材料层20从显示区域11延伸至非显示区域12时，有机发光材料层20在第二凹槽处60断开，封装层30在第二凹槽60处连续。
具体的，封装层30包括连接部301，连接部301覆盖第二子凹槽61。也即，封装层30在第二凹槽60处通过连接部301连接。
请参阅图11，图11为本申请实施例提供的OLED显示面板的第五种结构示意图。如图11所示，非显示区域12还设置有挡墙结构70。挡墙结构70靠近显示区域11的一侧的第二凹槽60的数量大于或等于1。挡墙结构70远离显示区域11的一侧的第二凹槽60的数量大于或等于3。
具体，设置在非显示区域12的多个第二凹槽60沿着显示区域11朝向非显示区域12的方向间隔设置，从而可以更好的避免切割时产生裂缝朝向显示区域11延伸，进而提高了OLED显示面板的封装效果。
其中，第一凹槽40的宽度与相邻第一凹槽40之间的间距之和与第一凹槽40的数量的乘积大于或等于预设切割精度。需要说明的是，切割精度为在外形差不多的OLED显示面板共用一种掩膜板的同时，通过在需要进行外形修剪的区域进行修剪切割时的切割精度。此外，该显示面板100是切割好了的显示面板，在非显示区域12并不会留下很多数量的第一凹槽40，剩余的第一凹槽40可能不满足这个关系。
请参阅图12，图12为本申请提供的电子设备的结构示意图。该电子设备200可以包括OLED显示面板100、控制电路91以及壳体90。需要说明的是，图11所示的电子设备200并不限于以上内容，其还可以包括其他器件，比如还可以包括摄像头、天线结构、指纹解锁模块等。
其中，OLED显示面板100设置于壳体90上。OLED显示面板具体可参照以上的描述，在此不做赘述。

其中，该控制电路91安装在壳体90中，该控制电路91可以为电子设备200的主板，控制电路91上可以集成有电池、天线结构、麦克风、扬声器、耳机接口、通用串行总线接口、摄像头、距离传感器、环境光传感器、受话器以及处理器等功能组件中的一个、两个或多个。
其中，该OLED显示面板100安装在壳体90中，同时，该OLED显示面板100电连接至控制电路91上，以形成电子设备200的显示面。该OLED显示面板100可以包括显示区域和非显示区域。该显示区域可以用来显示电子设备200的画面或者供用户进行触摸操控等。该非显示区域可用于设置各种功能组件。
电子设备包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
第一方面，本申请提供的电子设备，由于在非显示区域设置有第一凹槽，且有机发光材料层以及封装层均在第一凹槽处断开，从而在进行外形修剪切割时可以截断切割裂纹；也即，在外形差不多的OLED显示面板共用一种掩膜板的同时，通过在需要进行外形修剪的区域设置第一凹槽可以避免切割时产生裂缝朝向显示区域延伸，进而提高了OLED显示面板的封装效果。
第二方面，本申请提供的电子设备，在显示区域与第一凹槽之间还设置有第二凹槽，且有机发光材料层在第二凹槽处断开，进一步防止裂缝朝显示区域延伸；同时，封装层在第二凹槽处连续，从而可以保证OLED显示面板的侧向封装效果，有效防止水汽氧气从第二凹槽处侵入，提高显示面板侧向封装的可靠性。
