在本发明的另一个实施例中，显示屏71可包括盖板玻璃711、触摸面板712、显示内屏713。
其中，盖板玻璃711位于显示屏71的最上层，其作用主要在于保护触摸面板712。
触摸面板712则设置于盖板玻璃711的下方，被盖板玻璃711覆盖。其主要用于接收用户的触摸操作。
显示内屏713，设置在触摸面板712的下方，被触摸面板712覆盖，其主要用于接收显示数据进行显示。
在本发明的一个实施例中，以红外线为例进行说明。信号发射器731发射红外光，红外光经由通孔穿过显示屏71，直至照射到外界物体表面。信号接收器732可接收外界物体表面反射的红外光。其中，反射的红外光可穿过显示屏71及通孔，照射到信号接收器732。处理器74可根据红外光的强度，对外界物体距离显示屏的接近状态进行检测。没有任何物体遮挡的时候，接收端的数值是最小的，在物体不断靠近的时候，数值不断变大，直到满量程为止。举例来说，正常无物体遮挡的时候，数值为50；当人脸全部贴近移动终端时，红外线全部反射到红外接收端，此时数值为1024。一般情况下，会设置离人脸在3-5cm的时候，开始熄屏。例如移动终端在亮屏状态下，人脸逐渐靠近，数值随之变大，当数值大于300时开始熄屏；在熄屏状态下，人脸逐渐远离，数值随之变小，当数值小于300时开始亮屏。
本发明实施例的终端设备，通过将传感器组件设置显示屏的下方，避免了对显示屏显示造成的影响，再利用传感器组件的信号发射器发射发射信号经由通孔穿过显示屏，再由 信号接收器接收发射信号经由外界物体反射的反射信号，来进行接近状态的检测，保证传感器组件隐藏在显示屏下方时，仍能实现接近状态检测。
为实现上述实施例，本发明还提出一种接近状态检测方法。
如图8所示，该接近状态检测方法，应用于终端设备。其中，终端设备包括显示屏；遮光片，遮光片设置于显示屏下方，且遮光片设有至少一个通孔；传感器组件，传感器组件设置在遮光片下方，传感器组件包括信号发射器和信号接收器。
接近状态检测方法包括以下步骤：
S81，控制信号发射器发出发射信号，发射信号经过通孔穿过显示屏。
在本发明的一个实施例中，可以预设电流和预设强度控制信号发射器发射发射信号。其中，预设电流为25～150毫安，预设强度为5～50毫瓦。例如：在信号发射器发射红外光后，红外光可按照从下到上的层次关系，依次穿过遮光片上通孔及整个显示屏直至照射到外界物体表面。与现有技术相比，如图9所示，现有技术中的红外光只需穿过盖板玻璃。因此，在本发明的实施例中，需要增加信号发射器发射红外光时的电流和强度，才能使红外光穿透整个屏幕的厚度。其中，波长850纳米或940纳米的红外线，其透过率可控制在3％-5％。
S82，控制信号接收器接收经由外界物体反射回的反射信号。
在本发明的一个实施例中，信号接收器可接收外界物体表面反射的反射信号。例如，反射的红外光可按照从上到下的层次关系，依次穿过整个显示屏以及遮光片上的通孔，最终照射到信号接收器。
S83，根据反射信号判断外界物体与终端设备之间的接近状态。
在接收到反射的反射信号之后，根据反射信号判断外界物体与终端设备之间的接近状态。
在本发明的一个实施例中，信号接收器可包括一个模数转换器，可将接收到的红外光进行转换，得到红外光对应的数值。没有任何物体遮挡的时候，接收端的数值是最小的，在物体不断靠近的时候，数值不断变大，直到满量程为止。举例来说，正常无物体遮挡的时候，数值为50；当人脸全部贴近移动终端时，红外线全部反射到红外接收端，此时数值为1024。一般情况下，会设置离人脸在3-5cm的时候，开始熄屏。例如移动终端在亮屏状态下，人脸逐渐靠近，数值随之变大，当数值大于300时开始熄屏；在息屏状态下，人脸逐渐远离，数值随之变小，当数值小于300时开始亮屏。
本实施例的接近状态检测方法，通过将传感器组件设置显示屏的下方，避免了对显示屏显示造成的影响，再利用传感器组件的信号发射器发射发射信号经由通孔穿过显示屏， 再由信号接收器接收发射信号经由外界物体反射的反射信号，来进行接近状态的检测，保证传感器组件隐藏在显示屏下方时，仍能实现接近状态检测。
为了实现上述实施例，本发明还提出一种终端设备。
图10为本发明一实施例提出的终端设备的结构示意图。
如图10所示，该终端设备100包括：壳体1001和位于壳体1001内的处理器1002、存储器1003和显示装置1004，其中，处理器1002通过读取存储器1003中存储的可执行程序代码来运行与可执行程序代码对应的程序，以用于实现如前述实施例的接近状态检测方法。
