显示单元140(即显示屏)可用于显示由用户输入的信息或提供给用户的信息以及终端设备100的各种菜单的图形用户界面(graphical user interface，GUI)。显示单元140可包括设置在终端设备100正面的显示屏141。其中，显示屏141可以采用液晶显示器、发光二极管等形式来配置。显示单元140可以用于显示本申请中所述的各种图形用户界面。触控屏131可以覆盖在显示屏141之上，也可以将触控屏131与显示屏141集成而实现终端设备100的输入和输出功能，集成后可以简称触摸显示屏或触摸屏。
终端设备100还可以包括至少一种传感器150，比如光传感器、运动传感器、加速度传感器。终端设备100还可配置有陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器。
音频电路160、扬声器161、麦克风162可提供用户与终端设备100之间的音频接口。音频电路160可将接收到的音频数据转换后的电信号，传输到扬声器161，由扬声器161转换为声音信号输出；另一方面，麦克风162将收集的声音信号转换为电信号，由音频电路160接收后转换为音频数据，再将音频数据输出至RF电路110以发送给比如另一终端设备，或者将音频数据输出至存储器120以便进一步处理。

如图2所示，为一种基于Android操作系统的终端设备的架构的示意图。包括硬件层、驱动层、硬件抽象层(hardware abstract layer，HAL)、框架层、应用层。
应用层的应用注册接近光事件，以要求打开接近光功能。接近光功能即指背景技术中所描述的通过接近光传感器来确定遮挡物靠近或远离的功能。虽然本申请可以不采用接近光传感器，而是采用触摸屏感应遮挡物靠近或远离，但是对于应用层中的应用而言，仍然注册接近光事件，不需要针对本申请的方案进行适配修改。
加速度传感器输出的加速度数据用于手势算法判断用户手势，比如拿起、放下。
触摸屏的集成电路(integrated circuit，IC)将触摸屏感应遮挡物的原始数据发送给触摸主机处理(touch host processing，THP)守护进程。
THP守护进程的THP算法根据用户手势、场景识别的结果(例如，通话、防误触)以及来自触摸屏的原始数据得到接近事件(例如，接近、远离)，并将接近事件上报给传感器管理器。
传感器管理器可以向THP守护进程发送开关控制指令。例如，传感器管理器可以根据THP守护进程发送的接近事件来下发关闭指令，使THP守护进程的THP算法休眠，达到降功耗的目的。传感器管理器还可以根据手势算法识别的用户手势来下发打开指令，使THP守护进程运行THP算法。
THP算法、手势算法可以运行在片上系统(system on chip，SOC)的应用芯片中，进一步的，为了降低功耗，手势算法可以运行在应用芯片的传感器集线器(sensorhub)芯片中。
本申请实施例可以应用于通话、第三方应用(例如微信)通话等场景。例如，当检测到用户移动终端设备的手势为抬起时，开始检测遮挡物是否靠近触摸屏，如果检测到遮挡物靠近触摸屏，则熄灭触摸屏以降低终端设备的功耗。当检测到用户移动终端设备的手势为放下时，开始检测遮挡物是否远离触摸屏，如果检测到遮挡物远离触摸屏，则点亮触摸屏以方便用户操作终端设备。
本申请实施例还可以应用于防误触场景。例如，终端设备置于口袋中，由于用户运动等原因误挤压了开机键，使得触摸屏被点亮，开始检测遮挡物与触摸屏的距离是否小于或等于预设值，如果小于或等于预设值，则显示提示信息，以提醒用户有遮挡物遮挡触摸屏。
如图3所示，本申请实施例提供了一种终端设备的显示控制方法，应用于上述终端设备和架构，该方法包括：
S301、满足第一预设条件时，获取触摸屏的多个帧的测量值。
测量值用于指示感应的遮挡物与触摸屏之间的距离。
示例性的，对于触摸屏为电容触摸屏时，测量值为电容值，只有当遮挡物与电容触摸屏距离较近时，电容触摸屏的电容值才会发生变化。并且电容触摸屏的电容值是以帧为单位进行反馈的，即可以获取电容触摸屏的多个帧的电容值。
可选的，在步骤S301之前，该方法还可以包括：获取终端设备的加速度，具体的，可以通过加速度传感器获取终端设备的加速度。根据加速度确定用户移动终端设备的手势，例如抬起、放下、旋转等。
在一种可能的实施方式中，满足第一预设条件包括：用户移动终端设备的手势为预设手势。例如，预设手势可以为抬起或放下，则当用户移动终端设备的手势为抬起或放下手势中 的一种时，才启动THP算法来检测遮挡物靠近或远离触摸屏，以熄灭或点亮触摸屏，可以降低功耗。
该实施方式可以应用于通话、第三方应用(例如微信)通话等场景。
在另一种可能的实施方式中，满足第一预设条件包括：触摸屏被点亮。进一步地，满足第一预设条件包括：在锁屏状态下并且防误触开关打开的情况下，触摸屏被点亮。
触摸屏被点亮的原因可以包括：点击HOME键、开机键、通知提醒、来电、插入通用串行总线(universal serial bus，USB)或耳机、连接蓝牙等。
该实施方式可以应用于防误触场景。
S302、根据多个帧的测量值确定遮挡物与触摸屏之间的距离。
示例性的，对于电容触摸屏来说，遮挡物与电容触摸屏之间的距离变小(即靠近)时，电容触摸屏与遮挡物靠近处的像素点的电容值变大；遮挡物与电容触摸屏之间的距离变大(即远离)时，电容触摸屏与遮挡物靠近处的像素点的电容值变小。根据电容值的变化趋势可以确定遮挡物与触摸屏之间的距离的变化趋势(即靠近或远离)。
S303、当上述距离满足第二预设条件时，控制所述触摸屏执行预设操作。
对于通话或第三方应用通话的场景，当预设手势为抬起，距离满足第二预设条件包括距离逐渐减小，则控制触摸屏执行预设操作可以包括：熄灭触摸屏。但此时仍然可以将触摸屏进入低功耗的上电状态，以准备快速响应点亮触摸屏的操作。当预设手势为放下，距离满足第二预设条件包括距离逐渐增加，控制触摸屏执行预设操作包括：点亮触摸屏。
对于防误触场景，距离满足第二预设条件包括距离小于或等于预设值，控制触摸屏执行预设操作可以包括：控制触摸屏显示提示信息，提示信息用于指示有遮挡物遮挡触摸屏。并且触摸屏不响应触摸操作。
需要说明的是，如图4所示，不满足第一预设条件时，不执行步骤S302-S303,可以执行步骤S304。
S304、控制触摸屏保持当前状态。
例如，对于通话或第三方应用通话的场景，如果确定手势不为预设手势，或者，未检测到手势，则可以继续保持亮屏。对于防误触场景，如果触摸屏未被点亮，或者在锁屏状态下并且防误触开关关闭的情况下，触摸屏被点亮，则不显示提示信息。
上述步骤可以由THP算法来执行，当熄灭触摸屏后经过预设时间后，THP算法进入休眠状态，只有当步骤S301中满足第一预设条件后才唤醒THP算法，以进一步降低功耗。
如图5所示，对于通话或第三方应用通话的场景，当距离逐渐增加时，可以执行步骤S305、S305、当上述距离逐渐增加时，点亮触摸屏。
点亮触摸屏使得用户可以操作触摸屏。
本申请提供的终端设备的显示控制方法和终端设备，利用触摸屏来检测遮挡物与触摸屏之间的距离，实现终端设备不采用接近光传感器情况下检测遮挡物与触摸屏之间的距离，并控制终端设备的触摸屏的显示。
示例性的，如图6所示，为通话或第三方应用通话的场景下，遮挡物与触摸屏的距离增加时，点亮触摸屏的耗时示意图。在传感器集线器上运行手势算法，根据加速度传感器得到的数据确定用户的手势为放下，将手势通过驱动层发送给硬件抽象层，硬件抽象层启动THP算法。在THP算法中，获取电容触摸屏的多个帧的电容值，并根据测量值确定遮挡物与触摸屏之间的距离，随着该距离增加，确定遮挡物远离触摸屏，因此通过驱动层向框架层发送远 离事件。框架层启动亮屏流程，并通知驱动层来完成亮屏流程。框架层向驱动层下发背光指令来点亮触摸屏。
