具体实施方式
下面将详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。基于本申请中的实施例，本领域普通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。
本申请的说明书和权利要求书中的术语“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是 一种“或”的关系。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
如图1至图5所示，本申请实施例提供一种显示模组，该显示模组包括显示层10和保护层20，显示层10可以理解为显示模组的发光层，其可以集成发光阵列和驱动阵列是显示模组的核心显示部分，保护层20用于对显示层10进行保护，其中：
显示层10包括相背设置的第一侧和第二侧，第一侧为显示层10的显示面所在的一侧；
保护层20层叠设于显示层10的第二侧，保护层20包括保护层主体21和保护垫22，保护层主体21上设有通孔23，保护垫22可拆卸的设置于通孔23内；
其中，在保护垫22从通孔23中拆卸下来的情况下，通孔23用于安装功能模块。
本实施方式中，可以通过设置预设切割线的方式，将保护垫可22可拆卸的设置于通孔23内。比如，可以通过切换设备在保护层主体21上设置预设切割线，并通过预设切割线将保护层20分割形成保护层主体21和保护垫22。可以理解的是，当保护垫22从保护层主体21上取下来的时候，保护层主体21上的容置保护垫22的区域，即预设切割线所围设的区域会形成一通孔23，即保护垫22与保护层主体21的连接关系可以理解为保护垫22可拆卸的设置于保护层主体21的通孔23内。
其中，保护垫22还可以与通孔23的内壁间隙连接，以实现保护垫22可拆卸的设置于通孔23内。
这样当需要将保护垫22从保护层主体21上拆卸下来的时候，可以通过外力撕扯的方式，以破坏保护层主体21和保护垫22之间的所残存的连 接结构，并使保护垫22从保护层主体21上脱离，即将保护垫22从通孔23中拆卸下来，从而达到在保护层主体21上灵活开设通孔的目的。
其中，保护层主体21和保护垫22之间的所残存的连接结构可以理解为经预设切割线切割后所残存的连接结构，该残存的连接结构相对于未被预设切割线切割的连接结构表现为间隔分布，且该残存的连接结构在外力的作用下，容易被扯断，进而使保护层主体21和保护垫22能够完全脱离，并使得保护垫22可以从保护层主体21中取出，并在对应保护垫22的位置形成如图4所示并用于安装功能模块的通孔23。
需要说明的是，在保护层20未设置预设切割线的情况下，保护层主体21和保护垫22为一体结构；如图3所示，通过在保护层20上设置预设分隔线，以使保护层20分割形成保护层主体21和保护垫22，即使保护层主体21和保护垫22之间的连接转变为可拆卸连接，比如通过外力的撕扯将保护垫22从保护层主体21的通孔23中拆下来，以便在通孔23内安装对应的功能模块。
而且，该通孔23可以用于安装功能模块，以便将功能模块集成设置在显示模组上，从而使得包括显示模组的电子设备能够同时兼顾集成更多的功能和提供更大的屏幕，并达到提升显示模组的兼容性的目的。
可以理解的是，保护垫22的形状和数量可以基于需要集成设置在显示模组上的功能模块的类型和型号确定。比如，需要在显示模组上集成3种功能模块的情况下，则可以在保护层20上形成3种保护垫22，以便在需要安装对应的功能模块的时候，可以通过外力撕扯的方式，将对应的保护垫22从保护层主体21上脱离，从而形成对应的安装孔，并实现功能模块的安装。
这样通过将保护垫22设置成可拆卸结构，并可以在需要的时候，将对应的保护垫22从保护层主体21上拆除或拆下，使得在保护层主体21上形成对应的通孔23，从而实现通孔23的灵活设计，有效的提升了显示模组上的功能模块安装孔的扩展的灵活性。
可选地，功能模块包括超声波指纹传感模块、光电指纹传感模块、红外光敏传感模块、压感传感模块、屏下摄像头模块中的至少一项。
可选地，如图1所示，保护垫22和第二侧之间设有脱离层30，脱离层30在显示面上的正投影位于通孔23在显示面上的正投影内。
本实施方式中，通过在保护垫22和显示层10之间设置脱离层30，即在显示层10的对应保护垫22的位置设置脱离层30，即避免在保护垫22和显示层10之间设置粘接层，可以降低保护垫22和显示层10之间的粘接力，从而使得保护垫22可以更好从保护层主体21上脱离。
其中，脱离层30在显示面上的正投影位于通孔23在显示面上的正投影内可以理解为脱离层30仅设置在显示层10的正对保护垫22的区域内。
另外，需要说明的是，保护层20和显示层10之间可以通过第二粘接层40粘接固定；而且，保护层20包括层叠设置的泡棉层和涤纶树脂层，且泡棉层位于第二粘接层40和涤纶树脂层之间。
可以理解的是，本申请中的保护层20用于对显示层10的第二侧进行保护，即可以在显示层10的第二侧通过层叠设置泡棉层和涤纶树脂层的方式形成保护层20，以达到保护显示层10的目的。
可选地，为避免脱离层30的厚度影响显示模组的整体高度，可以选用涤纶树脂材料形成脱离层，即选用聚对苯二甲酸乙二酯(Polyethylene Terephthalate，PET)材料制备脱离层；而且，脱离层30的厚度可以为1微米～10微米。
进一步地，脱离层30的边缘和预设切割线之间还可以预留间隙，以避免在显示层10的第二侧设置脱离层30的时候，脱离层30会延伸至保护层主体21和显示层10的粘接区域，避免在撕扯保护垫22的时候，连带撕扯保护垫主体21，并达到提升显示模组的结构可靠性的目的。
其中，脱离层30的边缘和通孔23的内壁之间的间隙为0.3毫米～0.7毫米。
一示例中，脱离层30的边缘和预设切割线之间的间隙为0.5毫米，以避免脱离层30延伸至保护层主体21和显示层10的粘接区域。
另外，需要说明的是，脱离层30设置在第二粘接层40和显示层10之间，且脱离层30在显示层10上的覆盖区域位于预设切割线在显示层10上的正投影内。这样通过脱离层30以隔断保护垫22的粘接层和显示层10 之间的粘接力，以便在撕扯保护垫22的时候，可以避免粘接层对显示层10造成损伤。
可以理解的是，第二粘接层40也可以是保护层20的一部分，即保护层20包括依次层叠设置的第二粘接层40、泡棉层和涤纶树脂层，且预设切割线也依次切割第二粘接层40、泡棉层和涤纶树脂层，并将保护层20分割形成保护层主体21和保护垫22，最终形成的保护层主体21和保护垫22均包括依次层叠设置的第二粘接层40、泡棉层和涤纶树脂层。
可选地，还可以在保护垫22的背离显示面的一侧设置把手部24，且把手部24与保护垫22之间可以通过第一粘接层25连接。
其中，第一粘接层25可以是双面胶或者胶水层，从而达到降低第一粘接层25的设置成本的目的
本实施方式中，通过设置把手部24，可以方便用户或操作员对保护垫22施加撕扯力，以提升保护垫22从保护层主体21上脱离的脱离效率。
进一步可选地，显示模组还包括金属保护层50，金属保护层50设于保护层20的背离显示面的一侧，且金属保护层50的对应保护垫22的区域设有开孔51，把手部24收容于开孔51内。
本实施方式中，通过设置金属保护层50可以对显示模组进行进一步保护，金属保护层50可以起到保护屏幕的作用；而且，通过将把手部24收容在金属保护层50的开孔51内，还可以降低把手部24的设置对显示模组的整体高度的影响。
一示例中，把手部24可以为设置在保护垫22上的撕手。
其中，金属保护层50可以为铜箔层。
而且，为进一步降低把手部24对显示模组的整体高度的影响，可以将把手部24和第一粘接层的层叠高度小于或等于金属保护层50的厚度设置。
其中，设置于金属保护层50上的开孔51不仅包括保护垫22的脱离通道，还包括把手部24的容置空间以及用户或操作员的操作把手部24的操作空间，以便用户或操作员对把手部24施加撕扯力。
这样通过本申请提供的显示模组，可以在需要的时候，将对应的保护 垫22从保护层主体21上脱离，以形成对应的通孔，以实现通孔的开孔的需求；同时在不需要开孔的情况下，可以保留保护垫22，以避免多余的开孔对显示模组的整体影响。而且相对于直接开设所有可能需要的通孔，这样在某些通孔不需要的安装对应的功能模块的情况下，还需要将多余通孔进行遮挡或填充，使得显示模组的工艺变得复杂。
另外，多余的通孔在没有保护层保护的情况下，还容易在运输或生产的过程中在显示层10上形成异物，并使得显示层10出现黑团或黑点等不良现象，并影响显示模组的显示效果。而通过本申请的方案，则可以避免在显示层10上出现黑团或黑点等现象，并达到改善显示模组的显示效果的目的。
如图5所示，需要在显示模组上集成超声波传感器60的情况下，可以通过镊子等工具，对把手部24施加拉力或撕扯力，以便是对应的保护垫22从保护层主体21上脱离，并形成超声波传感器安装孔，从而使得超声波传感器60可以粘接的方式安装在对应的通孔内，且超声波传感器60与通孔的侧壁之间的间隙，可以通过设置遮光层70。
其中，遮光层70的厚度可以小于或等于金属保护层50的厚度，比如，遮光层70的厚度和金属保护层50的厚度均可以是0.03毫米；因此，遮光层70的设置不会影响显示模组的整体高度。
另外，超声波传感器60的外接电路板与显示模组的电路板之间可以通过连接器电连接，比如可以通过板对板连接器实现超声波传感器60的外接电路板与显示模组的电路板的电连接，以使超声波传感器60检测到的信号可以通过显示模组的电路板连接到整机，进而实现电子设备的指纹功能。
可以理解的是，本示例中的超声波传感器60还可以是其他功能器件，比如光电指纹传感模块、红外光敏传感模块、压感传感模块、屏下摄像头模块等等。
一示例中，显示层10的厚度为0.088毫米，泡棉层和第二粘接层40的叠加厚度为0.162毫米，涤纶树脂层的厚度为0.05毫米，金属保护层50的厚度为0.03毫米。
需要说明的是，上述示例中的厚度参数为本申请的显示模组的参考厚度，本申请实施例提供的显示模组的各部件的厚度参数还可以是其他厚度数据，在此不做限定。
本申请实施例还提供一种电子设备，包括上述显示模组。
需要说明的是，上述显示模组实施例的实现方式同样适应于该电子设备的实施例中，并能达到相同的技术效果，在此不再赘述。
其中，电子设备可以是为手机、平板电脑、笔记本电脑、掌上电脑、车载电子设备、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本或者个人数字助理(personal digital assistant，PDA)等。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
