具体实施方式
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。
需要说明的是，在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
根据背景技术，我们了解到，绝缘薄膜17与密封层15覆盖程度不一样，对Cell制程限制及产品品质都存在差异性。相关实施例中，提供一种绝缘薄膜17与密封层15没有覆盖的结构面板，具体请参阅图1所示，该结构绝缘薄膜17涂布局域小，附着力好。另外的，提供另一种绝缘薄膜17与密封层15没有覆盖的结构面板，具体请参阅图2所示，该结构绝缘薄膜17涂布局域中等，附着力一般。另外的，提供又一种绝缘薄膜17与密封层15没有覆盖的结构面板，具体请参阅图3所示，该结构绝缘薄膜17涂布局域大，附着力差。
本申请实施例提供一种显示面板和显示装置，以下对显示面板做详细介绍。
请参阅图4，图4为本申请实施例提供的显示面板侧视图。其中，显示面板10包括驱动电路层11、金属层12、绝缘层13、塑料层14、密封层15、挡墙16以及绝缘薄膜17，驱动电路层11具有相对设置的第一面11a和第二面11b，金属层12设置在所述第一面11a，所述金属层12之间具有间隙121，绝缘层13，设置在所述金属层12远离所述驱动电路层11的一面且嵌入所述间隙121中，塑料层14设置在所述绝缘层13远离所述驱动电路层11的一面，密封层15覆盖在所述塑料层14远离所述驱动电路层11的一面，挡墙16所述挡墙16从第一面11a延伸至密封层15中，且所述挡墙16位于所述驱动电路层11的中间位置，绝缘薄膜17设置在所述塑料层14和所述密封层15之间，且位于所述挡墙16的一侧。
需要说明的是，驱动电路层11的第一面11a为上表面，驱动电路层11的第二面11b为下表面，当然，在一些实施例中，第一面11a和第二面11b的位置可以互换。
另外的，金属层12包括栅极金属层12。金属层12之间具有间隙121。本申请实施中对金属层12不过多赘述。
另外的，绝缘层13通过沉积形成到金属层12上，绝缘层13材料可以SiNx/SiOx。当然绝缘层13还可以采用其他材料。本申请实施例中不过多赘述。
另外的，塑料层14为聚合型塑料。比如，全氟丙基全氟乙烯基醚与聚四氟乙烯的共聚物塑料。当然塑料层14也可以是其他类型的塑料。本申请中不过多赘述。
另外的，密封层15可以采用密封胶。本申请实施例中对密封胶材料不做具体限定。
另外的，绝缘薄膜17为聚酰亚胺薄膜，当然绝缘薄膜17也可以采用其他材料。本申请实施例中不过多赘述。
请参阅图5，图5为本申请实施例中显示面板的俯视图。其中，所述挡墙16为波浪状、连续凸起状以及锯齿状中的任一种。本申请实施例中的挡墙16采用这种结构可以缓解密封层15涂布地形的影响，从而减轻密封层15因为涂布地形而容易产生断胶的影响。
其中，所述挡墙16位于所述间隙121内。可以理解的是，将当前设置于金属层12的间隙121内，在设置挡墙16时，能够更加方便。不会使得挡墙16影响金属层12。
其中，所述挡墙16的宽度为20um～40um。可以理解的是，挡墙16的宽度可以为20um、25um、30um、35um以及40um等。本申请实施例中，挡墙16的宽度设置在这个范围不仅可以起到阻挡绝缘薄膜17与密封层15全部覆盖的作用，还能够阻挡水汽进入显示区。
其中，所述挡墙16通过半色调掩膜板形成。挡墙16通过半色调掩膜版形成，这种方式能够快速的形成挡墙16，减少工艺流程，提高生产效率。
其中，所述挡墙16的高度范围为1.0um～2.5um。可以理解的是，挡墙16的高度可以为1um、1.5um、2um、2.5um等。本申请实施例中，挡墙16的高度设置在这个范围不仅可以起到阻挡绝缘薄膜17与密封层15全部覆盖，还能够阻挡水汽进入显示区。
其中，显示面板10还包括透明导电薄膜18，所述透明导电薄膜18设置在所述密封层15远离所述驱动电路层11的一面。
请参阅图6，图6为本申请实施例提供的另一种显示面板结构示意图。其中，所述驱动电路层11包括环形区域111和路线区域112，所述环形区域111和路线区域112相邻设置，所述挡墙16设置在所述路线区域112上。
在一些实施例中，绝缘薄膜17设置在环形区域111。
本申请实施例所提供的显示面板10包括驱动电路层11、金属层12、绝缘层13、塑料层14、密封层15、挡墙16以及绝缘薄膜17，驱动电路层11具有相对设置的第一面11a和第二面11b，金属层12设置在所述第一面11a，所述金属层12之间具有间隙121，绝缘层13，设置在所述金属层12远离所述驱动电路层11的一面且嵌入所述间隙121中，塑料层14设置在所述绝缘层13远离所述驱动电路层11的一面，密封层15覆盖在所述塑料层14远离所述驱动电路层11的一面，所述挡墙16从第一面11a延伸至密封层15中，且所述挡墙16位于所述驱动电路层11的中间位置，绝缘薄膜17设置在所述塑料层14和所述密封层15之间，且位于所述挡墙16的一侧。本申请在驱动电路层11中间位置设置挡墙16，可以在绝缘薄膜17涂布过程中起到挡墙16作用，防止绝缘薄膜17与密封层15全部覆盖，提高显示面板10的附着力及高温高湿的信赖性，从而提高显示面板10的质量。
请参阅图7，图7为本申请实施例提供的显示装置的结构示意图。其中，显示装置100包括以上所述的显示面板10和边框20。所述边框20设置在所述显示面板10的周缘。上述实施例已经对显示面板10进行了详细描述。本申请实施例中对显示面板10不做过多赘述。由于本申请实施例中使用上述实施例中的显示面板10，因此，也继承了上述实施例中显示面板10的所有有益效果。
以上对本申请实施例提供的显示面板和显示装置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。
