可以预见的是，电子设备功能器件种类繁多，布局方式也各有不同，以手机为例，不同规格、型号的手机，其内部功能器件的种类、设置位置等必然不同，这样就需要开发多套屏幕，具体来说，这些屏幕预留有不同大小和位置的安装区域，以匹配不同组合方式的功能器件。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例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，本领域普通技术人员在没有做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。
请参考图1～图10，本申请公开一种电子设备，该电子设备可以是手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表、智能眼镜)等，本 申请实施例不限制电子设备的具体种类。
电子设备可以包括屏幕组件100、功能器件和设备主体600。设备主体600可以为电子设备的安装基础、并能够为电子设备提供工作用电。具体来说，设备主体600可以为电子设备的壳体，壳体可包括中框以及电池盖。屏幕组件100可以叠置于设备主体600，屏幕组件100与设备主体600粘接。功能器件可以设于设备主体600中。其中，屏幕组件100所在侧为电子设备的显示侧，用户可以通过屏幕组件100观测电子设备所显示的图像信息。设备主体600内还可以设置电源，以使功能器件与设备主体600进行电连接，以便为功能器件提供工作用电，这样电子设备可通过功能器件实现相应的功能，比如功能器件为镜头、指纹模组等元器件。
本申请中屏幕组件100朝向设备主体600的一侧具有第一镂空区域200，通常来说，屏幕组件100朝向设备主体600的一侧为背光侧、而背离设备主体600的一侧为显示侧，并且屏幕组件100通过挖去背光侧的部分材料以形成第一镂空区域200。
第一镂空区域200的设置可防止对功能器件造成阻光、屏蔽等异常干扰，以使功能器件能够有效实现其对应功能。就具体布局方式来说，功能器件可以朝向第一镂空区域200进行设置，并且第一镂空区域200在电子设备的厚度方向上的正投影可容纳至少两个功能器件，这里的厚度方向为屏幕组件100和设备主体600的叠置方向。
可选地，功能器件可以是指纹模组、镜头等，当屏幕组件100叠置于设备主体600时，两者相互配合可以对功能器件形成包覆效果，使功能器件位于屏幕组件以及设备主体之间。在一种可选的实施例中，至少两个功能器件可以设置于第一镂空区域200中，且至少两种功能器件朝向第一镂空区域，此种设置下至少两个功能器件是和屏幕组件100复用堆叠高度，从而不占用电子设备的内部空间，进而减小电子设备厚度。在另一种可选的实施例中，设备主体600内设有安装空间，至少两个功能器件设置在安装空间中，此种 设置下至少两个功能器件是位于屏幕组件100外，且朝向第一镂空区域200，此种设置更简便、且易操作。
由于第一镂空区域在电子设备的厚度方向上的正投影可容纳至少两个所述功能器件，因此，可实现用一套屏幕应对不同组合方式的功能器件，以使电子设备具有更好的兼容性能，进而将降低电子设备的开发成本。其中，功能器件的不同组合方式是指具有不同数量的同一功能器件组合，例如两个光电指纹模组的组合，三个摄像头的组合等；也可以指相同数量的不同功能器件的组合，例如一个光电指纹模组和一个超声指纹模组的组合，一个光电指纹模组和一个摄像头的组合等；还可以指不同数量的不同功能器件的组合，例如一个光电指纹模组和两个超声指纹模组以及一个摄像模组的组合等。
进一步地，屏幕组件100可以为柔性屏幕组件，以使电子设置能够通过绕卷、折叠等方式实现便携式携带。柔性屏幕组件可以包括依次叠置的盖板层110、触控层120、粘贴层130、140、支撑层150和散热层160，其中盖板层110背离设备主体600。在本申请的一种实施例中，触控层120、粘贴层130、140、支撑层150和散热层160设置在设备主体600中。在本申请的另一种实施例中，触控层120、粘贴层130、140、支撑层150和散热层160朝向设备主体600，但由于散热层与设备主体的边缘接触，因此触控层120、粘贴层130、140、支撑层150和散热层160并未设置于设备主体中。
其中，盖板层110可以是柔性塑料盖板，以便保持良好的透光性能，使用户可以观测到电子设备所显示的图像；触控层120可以采用电容膜层(P-film膜)等制作，使用户可以对电子设备进行接触式操作，并显示内容；粘贴层130和粘贴层140可以是粘胶层和泡棉层的叠层组合结构，比如粘贴层130为粘胶层，粘贴层140为泡棉层，泡棉层可以起到阻光和缓冲保护的作用，粘胶层起到连接作用；而支撑层150可对整个屏幕组件100进行支撑定型，并发挥绝缘和防刺穿的作用，可以采用聚酰亚胺塑料进行制作；散热层160可以实现散热和信号屏蔽的作用，可采用铜箔等材料进行制作。
第一镂空区域200可以设置于粘贴层130、140、支撑层150和散热层160。以功能器件为指纹模组为例，指纹模组可以设置于设备主体中，并朝向第一镂空区域200，用户可在盖板层110一侧、并通过触控层120实现对指纹模组的触控式操作，从而完成人机交互。
可选地，屏幕组件100也可以为硬屏，此种设置下盖板层110可以为3D玻璃盖板，同理，第一镂空区域200可以设置于粘贴层130、140、支撑层150和散热层160，而根据功能器件可实现的功能不同，功能器件可以设置在第一镂空区域200中，或者功能器件与第一镂空区域200相对设置，这里不再详述。
进一步地，粘贴层130、140可以具有第一通孔，支撑层150上可以具有第二通孔，散热层160上可以具有第三通孔。第三通孔在电子设备的厚度方向上的正投影可容纳第一通孔和第二通孔，第二通孔在电子设备的厚度方向上的正投影面积大于或等于第一通孔在电子设备的厚度方向上的正投影面积。第一通孔、第二通孔和第三通孔连通，且围合成第一镂空区域200。
具体来说，第一通孔和第二通孔位于第三通孔在电子设备的厚度方向上的正投影中，第一通孔位于第二通孔在电子设备的厚度方向上的正投影中。这样可以提高设置功能器件时的密封性能。具体来说，如图1和图2所示，第三通孔在支撑层150上第三投影，即上述的正投影。而第二通孔位于第三投影内，同时支撑层150位于第三投影内的部分形成第一密封边201，该第一密封边201对第二通孔进行围绕，功能器件与第一镂空区域200进行匹配时，无论功能器件设于第一镂空区域200内还是设于第一镂空区域200外时，均可以将功能器件朝向第一镂空区域200一面的周缘与第一密封边201进行贴合，从而使功能器件和第一镂空区域200之间形成密封，此种密封不仅可以实现防水防尘，而且用户观看电子设备时，由于第一密封边201的止挡作用，可以排除功能器件和第一镂空区域200之间的缝隙，进而使用户无法看到电子设备的内部结构，加强电子设备的外观性能。
这里需要说明的是，第二通孔在电子设备的厚度方向上的正投影也可以容纳第一通孔，即第二通孔的横截面积也可以大于第一通孔，这样形成的第一密封边201能都得到粘贴层130、140的支撑，不会呈现“悬臂”的结构，进而保证安装功能器件时稳定性和牢固性。
可选地，功能器件可以包括光学指纹模组500和超声指纹模组300，且光学指纹模组500和超声指纹模组300可以并列设置于设备主体600中。
具体来说，光学指纹模组500和超声指纹模组300均可以设置在设备主体600中，且光学指纹模组500和超声指纹模组300沿第二方向依次设置，该第二方向与电子设备的厚度方向相交，比如相互垂直。这样，光学指纹模组500和超声指纹模组300不会相互遮挡或者干扰，从而影响其效果。当然，光学指纹模组500和超声指纹模组300分别距离屏幕组件的距离可以相等也可以不相等。在一些情况下，光学指纹模组500由于其本身性能参数需要距离屏幕组件较近，那么光学指纹模组500和超声指纹模组300分别距离屏幕组件的距离不相等。对于光学指纹模组500和超声指纹模组300分别距离屏幕组件的距离可以根据实际参数进行确定。其中，光学指纹模组500可以通过感知光线的方式实现指纹解锁等操作，超声指纹模组300可以通过超声等方式实现指纹解锁操作。可见，第一镂空区域200可以使光学指纹模组500、超声指纹模组300均与屏幕组件100实现较好的匹配，进而使电子设备实现不同的指纹解锁方式。
可选地，如图2所示，第一镂空区域200可以包括第一子区域210和第二子区域220。
其中，超声指纹模组300可设置于第一子区域210，并且超声指纹模组300通过胶层与触控层120连接，胶层的设置可以使超声指纹模组300牢固地粘接在触控层120上，进而保证两者相对位置的固定。同时需要说明的是，胶层的厚度可以较大，此种设置一方面可以保证连接的牢固性，另一方面可以调整超声指纹模组300相对于触控层120的间距，以使超声指纹模组300 更靠近设备主体600，这样保证超声指纹模组300有效使用的同时，用户不会从屏幕组件100观测到超声指纹模组300，以保证电子设备的外观性能。
而光学指纹模组500可以设置于第二子区域220，并且光学指纹模组500可以通过第一遮光层和第一保护层与触控层120连接。其中第一遮光层可以为泡棉，泡棉的设置可以排除杂散光的干扰，还可以解决由于第一镂空区域200的大面积镂空，从而造成的光线从盖板层110进入，进而造成透底的问题。而第一保护层可以采用聚对苯二甲酸类塑料(PET塑料薄膜)制作，以实现对第一遮光层的支撑定型、以及防尘防水等。
进一步地，第一遮光层朝向散热层160的平面可以与支撑层150朝向散热层160的平面共面，第一保护层朝向设备主体600的平面可以与散热层160朝向设备主体600的平面共面。即第一遮光层可以设置在第二通孔中、并且与支撑层150复用堆叠高度；而第一保护层可以设置第三通孔中、并且与散热层160共用堆叠高度。而共面的设置方式，可以保证第一遮光层与支撑层150、以及第一保护层与散热层160的拼接无段差，进一步保证密封性能和遮光性能。
更为具体的，超声指纹模组300发挥功能是通过超声实现的，故胶层的厚度应当能够满足超声的穿透，并保证超声能够通过胶层传递至超声指纹模组300。而光学指纹模组500使用需要得到足够的光线照射，故第一遮光层和第一保护层应当具有一定的透光性能，本申请采用在第一遮光层和第一保护层上设置第四通孔，光学指纹模组500通过第四通孔朝向触控层120，该第四通孔设置在触控层120和光学指纹模组500之间，光线可依次通过盖板层110、触控层120和第四通孔进入所述光学指纹模组500，以保证光学指纹模组500的正常使用。当然光学指纹模组500也可以设置在该第四通孔内，这里不再详述。
在另一些可选的实施方案中，电子设备还可以包括遮挡组件400。遮挡组件400可以设置于屏幕组件100朝向功能器件的一侧，且遮挡组件400可 以遮挡至少部分第一镂空区域200。遮挡组件400能够在保留原有屏幕外观和功能的基础上，对具有第一镂空区域的屏幕组件的非发光部分进行最小化去除，有效提升屏幕组件100应用的灵活性，较大程度的提升屏幕组件100的使用价值。
可选地，遮挡组件400可以对第一镂空区域200进行局部遮挡，遮挡组件400可以和功能器件配合使用，具体配合方式如下：
在一种实施例中，当超声指纹模组300位于第一子区域210，光学指纹模组500位于第二子区域220时，此种情况下如果整个第一镂空区域200被填充满，此时可以不设置遮挡组件400。如果第一镂空区域200的设置面积较大，也就是说第一镂空区域200除了放置超声指纹模组300的第一子区域210以及放置光学指纹模组500的第二子区域220之外还有未放置其余功能器件的第三子区域，可以使用遮挡组件400将位于超声指纹模组300和第一子区域210之间的缝隙、光学指纹模组500和第二子区域220之间的缝隙、以及第三子区域这些位置进行遮挡。这样在保证功能器件正常使用的同时，可以使电子设备具有良好的外观性能。
在另一种实施例中，如图7～图10所示，当电子设备仅使用超声指纹模组300时，可以将超声指纹模组300设置在第一子区域210，而在第二子区域220设置遮挡组件400。在该实施例中，第二子区域220也可以设置光学指纹模组500，只是由于遮挡组件400的遮挡，光学指纹模组500无法从屏幕组件处获取光线，从而影响光学指纹模组500的正常工作。当然，为了保证设备主体600中的空间利用率，在第二子区域220中也可以不设置光学指纹模组500。
在又一种实施例中，如图3～图6所示，当电子设备仅使用光学指纹模组500时，可以将光学指纹模组500设置在第二子区域220，而在第一子区域210设置遮挡组件400。在该实施例中，第一子区域210也可以设置超声指纹模组300，只是由于遮挡组件400的遮挡，超声指纹模组300无法从屏 幕组件100处获取指纹数据，从而影响超声指纹模组300的正常工作。当然，为了保证设备主体600中的空间利用率，在第一子区域210中也可以不设置超声指纹模组300。同时，对于仅使用光学指纹模组500的情况来说，由于光学指纹模组500体积和所占用区域较小，光学指纹模组500无法将第二子区域220进行全部填充，故此种情况下遮挡组件400在遮挡填充第一子区域210的同时，遮挡组件400还需要对处于第二子区域220和光学指纹模组500之间的缝隙进行填充。此种设置下，可在遮挡组件400上开设避让孔403，避让孔403处于第二子区域220、并套设于光学指纹模组500外围，而遮挡组件400中位于第二子区域220、且对避让孔403进行围绕的部分，可对处于第二子区域220和光学指纹模组500之间的缝隙进行填充。
可选地，遮挡组件400也可以对第一镂空区域200进行全部遮挡，遮挡组件400可以和功能器件配合使用，具体配合方式如下：
在一种实施例中，当光学指纹模组500被设置在第二子区域220，以及超声指纹模组300被设置在第一子区域210，只是由于遮挡组件400遮挡于全部的第一镂空区域200，超声指纹模组300无法从屏幕组件100处指纹数据，从而影响超声指纹模组300的正常工作，光学指纹模组500无法从屏幕组件100处获取光线，从而影响光学指纹模组500的正常工作。当然，为了保证设备主体600中的空间利用率，在第一子区域210以及第二子区域220中也可以不设置超声指纹模组300和光学指纹模组500。这样使用遮挡组件400将整个第一镂空区域200进行填充止挡，可以保证电子设备的外观性能。
同时需要指出的是，本申请对遮挡组件400的形状并未做具体要求，设计原则为遮挡组件400能够与第一镂空区域200中需要遮挡部分的轮廓进行匹配，以达到遮光的目的，故遮挡组件400的轮廓形状可以如图6或者图10所示，也可以是其他任意形状，此处不再详述。
可选地，遮挡组件400可以包括第二遮挡层420和第二保护层410。其中第二遮挡层420可以为泡棉层，以达到遮光的目的，而第二保护层410可 以为聚对苯二甲酸类塑料(PET塑料薄膜)，以达到支撑定型以及完整密封的目的。具体来说，第二遮挡层420可以设置于第二保护层410上，第二遮挡层420朝向第一镂空区域200，且第二保护层410在电子设备的厚度方向上的正投影可容纳第二遮挡层420。
进一步地，第二遮挡层420可以与第二保护层410形状轮廓一致，并且第二保护层410的横截面积等于第二遮挡层420的横截面积。当然，第二保护层410的横截面积也可以大于第二遮挡层420的横截面积，此种情况下，第二遮挡层420在第二保护层410上形成第一投影，第一投影即上述的正投影，而第二保护层410中对第一投影进行围绕的部分将形成第二密封边401。这样安装遮挡组件400时，可将第二密封边401和第一密封边201进行叠置和贴合，并填充胶水进行粘接，此种设计可增加遮挡组件400的连接牢固性，并能够加强对第一镂空区域200密封效果，以及对屏幕组件100形成更好的遮光效果。
可选地，遮挡组件400还具有离型膜900，第二遮挡层420通过第二保护层410与离型膜900连接。在将遮挡组件400安装于第一镂空区域200的指定位置的过程中，可以通过将带有第二遮挡层420和第二保护层410的离型膜900安装在第一镂空区域200，然后将离型膜900与第二保护层410分离，从而能够将遮挡组件400保留在第一镂空区域200。这样能够方便在第一镂空区域设置遮挡组件400的操作。离型膜900的四周还设置有定位孔901，在将遮挡组件400安装于第一镂空区域200的过程中，可以通过夹具夹取。夹具通过定位孔901夹取带有第二遮挡层420和第二保护层410的离型膜，并将该离型膜900转移到屏幕组件100的第一镂空区域200。可选地，离型膜900上同时设置有拆卸线903，在遮挡组件400被安装于指定区域后，离型膜900与第二保护层410之间分离。可选地，离型膜900顶部设置有强弱胶902，弱胶面贴于屏自带保护膜，当撕去屏幕保护膜后，该离型膜900也自动被带起去除。这样能够在防止去除离型膜时损伤屏幕。
在另一些可选的实施方案中，功能器件还可以为摄像模组和/或红外模组，在此种情况下，屏幕组件100还可以包括第二镂空区域700，功能模组可以朝向第二镂空区域700。可见，第二镂空区域700的设置可以使摄像模组和/或红外模组的布局位置与屏幕组件100相匹配，进一步提高了电子设备的兼容性。
进一步地，电子设备还可以包括屏幕组件FPC800。屏幕组件FPC800设置于屏幕组件100朝向设备主体600的一侧。屏幕组件FPC800可以为屏幕组件100的正常工作提供电能，具体来说，设备主体600内可以设置电源，屏幕组件100可以通过屏幕组件FPC800电连接设备主体600，这样电源的电能可传输至屏幕组件100，以使屏幕组件100正常显示，用户可以在屏幕组件100上进行触控等操作。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
