在该实施例中，第二金属层在垂直于显示屏210的方向上的投影位于显示屏210的非显示区域，使得第二金属层与非显示区域对应设置，避免第一电极250遮挡显示屏210的像素单元，进而避免压感电容影响显示屏210的显示精度，提升屏幕模组的显示效果。
根据本发明的一些实施例，散热层100包括铜箔；第二金属层包括铜箔或金属膜。
在该实施例中，散热层100包括铜箔，使得散热层100可借用屏幕模组的铜箔层作为压感电容除第一电极250外的另一电极，进一步降低设置压感电容所需的材料成本。第二金属层包括铜箔或金属膜，铜箔或金属膜均可作为第一电极250与散热层100配合构成压感电容，进而提升压感电容对触控压力检测的准确性。
具体地，散热层100为屏幕模组靠近中框310一侧设置的铜箔，铜箔能够加快显示组件200的散热速度，以及能够将显示组件200的静电传导至中框310。

具体地，由于显示屏210单像素尺寸(pixel size)过小，将一定区域内的第一电极250连接，连接后的第一电极250与散热层100形成的大电容，单像素尺寸所对应的第一电极250和散热层100形成的小电容，大电容与小电容相比具备更优良的稳定性，进而实现对触控压力的精确检测。

在该实施例中，屏幕模组设置于壳体300上，实现对屏幕模组的安装和固定。柔性线路板400与压感电容电性连接，压感控制模块500与柔性线路板400电性连接，进而将压感电容的容值信号发送至压感控制模块500。主控模块600与压感控制模块500电性连接，压感控制模块500对容值信号进行处理后，再将处理后的容值信号发送至主控模块600，使得主控模块600可根据压感电容容值的变化来获取屏幕模组的触控压力，并根据屏幕模组的触控压力来对电子设备进行控制，实现通过触控压力进行人机交互，丰富电子设备的交互方式，提升用户对电子设备的体验感。
电子设备还包括壳体300，屏幕模组设置于壳体300上。
具体地，如图4和图5所示，屏幕模组包括四个区域，分别为区域B、区域C、区域D、和区域E，四个区域中每个区域的第一电极250相互连接，并且每个区域内的第一电极250与散热层100形成压感电容。四个区域分内的第一电极250分别通过显示屏210内部走线经柔性线路板400连接到压感控制模块500。同时再通过散热层100和柔性线路板400进行连接，连接后同样通过柔性线路板400连接到压感控制模块500。手指按压屏幕模组时，屏幕模组的四个区域的第一电极250与散热层100之间的电容会发生变化，通过压感控制模块500计算之后反馈给主控模块600，给出压感反馈。
具体地，屏幕模组也可包括六个区域、八个区域或更多区域。
具体地，如图4和图5所示，散热层100与柔性线路板400上的触点F电性连接。
根据本发明的一些实施例，如图5所示，压感控制模块500集成于柔性线路板400。
在该实施例中，压感控制模块500集成于柔性线路板400，压感控制模块500对来自压感电容的容值信号进行处理后，即可通过柔性线路板400将处理后的容值信号发送至主控模块600，无需在压感控制模块500和主控模块600之间设置额外的电性连接部件，进一步减小对电子设备内空间的占用。
根据本发明的一些实施例，如图1所示，壳体300包括中框310和盖体320；屏幕模组贴合于中框310的第一侧；盖体320扣合于中框310的第二侧。
