具体实施方式
下面结合附图和实施例对本文作详细说明。可以理解的是，此处所描述的 具体实施例仅仅用于解释本文，而非对本文的限定。
在更加详细地讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各步骤描述成顺序的处理，但是其中的许多步骤可以被并行地、并发地或者同时实施。此外，各步骤的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
黑屏手势功能是在移动终端(例如智能手机)处于熄屏休眠的情况下，触控显示屏以低功耗状态运行，以便在熄屏状态下检测作用于触控显示屏的触摸操作，确定该触摸操作对应的黑屏手势，并根据该黑屏手势来唤醒智能手机的某项功能或开启预先设置的与黑屏手势类型对应的应用程序的功能。为了便于理解黑屏手势功能，下面对由熄屏状态下检测到黑屏手势至应用层开启该黑屏手势对应的应用程序的流程进行说明，该流程包括：将黑屏手势对应的手势数据存入驱动层的预设节点内，其中，手势数据包括手势坐标和手势类型；由驱动层执行黑屏手势数据有效性判断；若有效，则由框架层执行黑屏手势事件派发；在应用层接收到黑屏手势事件后，由应用层从驱动层内预设节点读取手势坐标，根据该手势坐标和手势类型计算黑屏手势的动画轨迹，将动画轨迹数据发送至帧缓存(FrameBuffer)，以按照设定的屏幕刷新率将该动画轨迹刷新至显示屏，进行显示；随后，由应用层执行开启该黑屏手势对应的应用程序的操作。
目前，触摸芯片输出低于正常亮屏状态下的扫描频率的触摸感测控制信号至触控显示屏，使触控显示屏表面有小电流通过，从而使触控显示屏全屏处于检测黑屏手势的低功耗状态。但是，在一些场景下，用户可能长时间未输入黑屏手势，例如，会议场景或者夜间休息场景等。相关技术中，终端并不会根据用户的使用情况调整触控显示屏的耗电情况，导致终端的续航时间不长。本文实施例提供的黑屏手势的检测方案可以避免上述的终端续航时间较短的情况。
图1为本文实施例提供的一种降低移动终端功耗的方法的流程图，该方法可以由降低移动终端功耗的装置来执行，其中，该装置可由软件和/或硬件实现，一般可集成在移动终端中。如图1所示，该方法包括步骤110，步骤120，步骤130和步骤140。
在步骤110中，在熄屏状态下，获取指纹识别模组检测到的指纹。
其中，指纹包括指纹图案。指纹识别模组包括按压式指纹识别模组或触摸式指纹识别模组。对于按压式指纹识别模组，其在移动终端处于熄屏状态下，基于用户的触摸操作即可检测并识别指纹。需要注意的是，此时用户输入的触摸操作的按压压力不足以按下该按压式指纹识别模组，否则，在该按压式指纹识别模组被按下后，会触发显示屏点亮。对于触摸式指纹识别模组，其在移动 终端处于熄屏状态下，可以检测并识别用户输入的指纹。
若黑屏手势功能已开启且移动终端处于熄屏状态，则控制指纹识别模组进入检测指纹的工作模式，且控制触控显示屏进入不能检测黑屏手势的非工作模式(可以认为是休眠状态，无触摸感测控制信号输入，即不能检测作用于触控显示屏上的触摸操作)，从而避免因持续向触控显示屏全屏提供触摸感测控制信号，导致的移动终端的功耗较高的情况。
在一实施例中，应用层可以根据用户的配置操作确定黑屏手势功能是否开启。以用户配置黑屏手势的应用场景为例，若用户点击配置选项，并选择黑屏手势功能，终端的显示界面切换至黑屏手势功能配置界面。在该黑屏手势功能配置界面上用户可以点击开启黑屏手势功能，并设置启用哪些黑屏手势。此时，应用层修改代表黑屏手势功能开关状态的预设标识的取值，以表明当前黑屏手势功能已开启。由于显示屏在熄屏时会发送熄屏广播，根据该熄屏广播可以确定移动终端处于熄屏状态。移动终端在确定黑屏手势功能已开启且移动终端处于熄屏状态时，向指纹识别模组输出驱动信号，以使指纹识别模组进入工作模式，但是，不输出触摸感测控制信号至触控显示屏，以使触控显示屏处于不能检测黑屏手势的休眠状态。
在步骤120中，在所述指纹为非解锁指纹时，控制触摸芯片输出触摸感测控制信号至触控显示屏，所述触摸感测控制信号用于使所述触控显示屏进入检测黑屏手势的工作模式。
其中，触摸感测控制信号为控制触控显示屏工作，并能够检测黑屏手势的驱动信号，即触摸感测控制信号用于使所述触控显示屏进入检测黑屏手势的工作模式。指纹模板是由用户预先录入的指纹构成的指纹集合。获取指纹识别模组检测到的指纹后，将该指纹与移动终端内预先存储的指纹模板进行比对，根据比对结果确定该指纹是否为解锁指纹。例如，将该指纹的指纹图案与预先存储的指纹模板中的指纹图案进行匹配，判断指纹模板中是否存在与该指纹匹配的指纹图案。若存在，则确定该指纹为解锁指纹，基于该解锁指纹执行解锁操作；若指纹模板中不存在与该指纹匹配的指纹图案，确定该指纹为非解锁指纹。此时，通过驱动层控制触摸芯片输出触摸感测控制信号至触控显示屏。
在步骤130中，根据所述指纹来匹配用户具有操作权限的应用程序，获取所述应用程序对应的黑屏手势集合，所述用户为具有所述指纹的用户。
移动终端为用户提供权限设置选项，用户可以通过该权限设置选项设置不同用户可以操作的应用程序。在一实施例中，用户可以首次使用该黑屏手势功能时，录入指纹作为指纹模板，并选择与该指纹模板关联的应用程序。例如，对于机主本人，其具有最大的操作权项，可以操作本机上安装的所有应用程序。因此，在机主本人录入指纹后，可以指定本机上安装的所有应用程序为机主所 录入的指纹对应的应用程序。对于儿童，其具有一部分应用程序的操作权限。机主在该儿童录入指纹后，为其指定能够操作的部分应用程序，因此，该部分应用程序为儿童所录入的指纹对应的应用程序。对于没有在移动终端中录入指纹的陌生人，其仅具有打开照相机进行拍照，或者打开手电筒应用程序等不涉及用户隐私的应用程序的操作权限。可以采用第一白名单的形式记录指纹模板与具有操作权限的应用程序之间的关联关系。
可以理解的是，对于陌生人可以操作的应用程序可以由用户设置，还可以是由系统默认设置。
预先建立黑屏手势与应用程序或手机功能的关联关系，可以设定第二白名单存储黑屏手势与应用程序(如进程号或安装包名)或手机功能(如手机唤醒、会议模式或标准模式等工作模式切换)的关联关系。可以理解的是，建立黑屏手势与应用程序的关联关系的方式有很多种，本文实施例不作限定。例如，可以在移动终端出厂前为移动终端的设定功能或设定应用设置快捷启动功能，通过输入设定手势可以在熄屏状态下直接执行该设定功能或打开该设定应用。以手电筒为例，在移动终端出厂前预先设置手电筒具有快捷启动功能，通过输入黑屏手势“O”可以在熄屏状态下打开手电筒。又如，移动终端提供黑屏手势配置功能，在用户开启黑屏手势功能时，提示用户选择需要设置快捷启动功能的应用程序，并输入或选择该应用程序对应的黑屏手势，从而建立黑屏手势与应用程序的关联关系。
根据当前检测的与指纹模板匹配成功的解锁指纹，查询上述指纹模板与应用程序的关联关系可以确定具有该指纹的用户可以操作的应用程序。在一实施例中，在该指纹与预先存储的指纹模板匹配成功时，查询存储有该指纹模板与应用程序的关联关系的第一白名单，确定用户具有操作权限的应用程序；若该指纹与预先存储的指纹模板匹配失败，则将预设应用程序作为用户具有操作权限的应用程序。例如，根据当前检测的与指纹模板匹配成功的指纹查询第一白名单，确定用户对照相机应用、即时通信类应用(如微信、QQ等)及购物类应用(如淘宝、京东等)具有操作权限。又如，在当前检测的指纹与预先存储的指纹模板匹配失败时，确定具有该指纹的用户仅对照相机应用有操作权限。需要说明的是，在当前检测的指纹与预先存储的指纹模板匹配失败时，具有该指纹的用户在打开照相机应用后不能通过照相机应用界面直接进入图片库。例如，如果具有该指纹的用户想要进入图片库，则显示对话框提示用户输入指纹。
根据该具有操作权限的应用程序查询该第二白名单，确定该用户可以操作的应用程序对应的黑屏手势集合。
在步骤140中，在检测到属于所述黑屏手势集合的黑屏手势时，上报黑屏手势事件至应用层，以执行所述黑屏手势对应的操作。
若检测到触控显示屏上的触摸操作，则通过驱动层可以识别出该触摸操作对应的黑屏手势类型，根据所识别出的黑屏手势类型查询该黑屏手势集合，判断当前检测到的黑屏手势是否为该黑屏手势集合内的黑屏手势。若属于，则驱动层上报黑屏手势至应用层。
在一实施例中，在检测到黑屏手势时，触摸芯片将该黑屏手势对应的手势数据存入设定寄存器，并发送中断唤醒信号至内核层。内核层在接收到该中断唤醒信号后，执行系统唤醒操作。在系统唤醒后，内核层调用驱动层的中断处理函数，由触摸芯片的设定寄存器读取该手势数据，并存储于驱动层的预设节点内。驱动层基于该手势数据识别黑屏手势类型。根据所识别出的黑屏手势类型查询该黑屏手势集合，判断当前检测到的黑屏手势是否为该黑屏手势集合内的黑屏手势。例如，驱动层基于读取的手势数据识别出黑屏手势类型是“O”。根据该识别出的黑屏手势类型“O”查询黑屏手势集合。若该黑屏手势集合中存在黑屏手势“O”，则确定当前检测到的黑屏手势属于该黑屏手势集合。在当前检测到的黑屏手势属于该黑屏手势集合时，上报黑屏手势事件至应用层，以使应用层执行该当前检测到的黑屏手势对应的操作。
图2是本文实施例提供的一种安卓系统框架示意图。以图2所示的操作系统为安卓(Android)系统的移动终端为例，介绍本文实施例提供的黑屏手势功能的执行流程。如图2所示，安卓系统框架由下至上包括内核层210、核心类库层220、框架层230及应用层240。其中，内核层210提供核心系统服务，包括安全、内存管理、进程管理、网络协议栈及硬件驱动等。其中，将内核层210中的硬件驱动记为驱动层211，该驱动层211包括触控显示屏驱动以及摄像头驱动等。核心类库层220包括安卓运行环境(Android Runtime)和类库(Libraries)。其中，Android Runtime提供大部分在Java编程语言核心类库中可用的功能，包括核心库(Core Libraries)和Dalvik虚拟机(Dalvik VM)。每一个安卓应用程序是Dalvik虚拟机中的实例，运行在它们自己的进程中。类库供安卓系统的各个组件使用，包括如下功能：媒体库(Media Framework)、界面管理(Surface Manager)、关系数据库引擎(SQLite)及位图和矢量字体渲染(FreeType)等，其各个功能通过安卓系统的框架层230暴露给开发者使用。框架层230提供开发安卓应用程序所需的一系列类库，使开发人员可以进行快速的应用程序开发，方便重用组件，也可以通过继承实现个性化的扩展，其提供的服务包括组件管理服务、窗口管理服务、系统数据源组件、空间框架、资源管理服务及安装包管理服务等。应用层240上包括各类与用户直接交互的应用程序，或由Java语言编写的运行于后台的服务程序，包括桌面应用、联系人应用、通话应用、相机应用、图片浏览器、游戏、地图以及网页(web)浏览器等程序，以及开发人员开发的其他应用程序。
在一实施例中，在黑屏手势功能开启后，触摸芯片在检测到黑屏手势时，生成一唤醒信号，并发送该唤醒信号至内核层。通过该唤醒信号触发内核层执行系统唤醒操作。在系统唤醒后，内核层调用驱动层中断处理函数执行，驱动层通过该中断处理函数读取触摸芯片中手势数据，并将读取的手势数据存储在驱动层的预设节点内。其中，触摸芯片设置为输出触摸感测控制信号至触控显示屏，以检测触摸操作，识别作用于触控显示屏上的黑屏手势的手势坐标，将该手势坐标作为手势数据存储在自身的寄存器中。预设节点可以为文件节点，例如可以是proc-D目录下的虚拟文件节点。在数据读取完成后，驱动层判定该手势数据的有效性，有效性判定的方式有很多种，本实施例不作具体限定。例如，驱动层根据该手势数据包含的手势坐标确定手势类型，并将所确定的手势类型作为手势数据存储在该预设节点内。若该手势类型不是预设的黑屏手势，则判定手势数据无效。又如，驱动层统计该手势数据的数目，判定该数目是否满足绘制预设的黑屏手势的要求，若不满足绘制预设的黑屏手势的要求，则判定手势数据无效。在数据有效时，驱动层上报黑屏手势事件。该黑屏手势事件通过核心类库层传输至框架层，并通过框架层派发，达到应用层。应用层在获取到黑屏手势事件时，由驱动层的预设节点读取手势数据。在手势数据准备完成后，根据该手势数据包含的手势坐标计算出黑屏手势轨迹，将该黑屏手势轨迹绘制在显示屏上进行显示。然后，应用层基于所读取的手势数据中的手势类型，打开与该手势类型对应的应用程序。其中，手势类型可以是预先设置于移动终端中的用于实现某一功能的手势，还可以是用户自定义的手势。例如，手势类型可以是O，代表打开相机。又如，手势类型可以是V，代表打开手电筒等等。
可以理解的是，黑屏手势功能的执行流程并不限于本实施例中列举的方式。例如，还可以是在系统唤醒时即上报黑屏手势事件，内核层调用驱动层中断处理函数，驱动层通过该中断处理函数读取触摸芯片中手势数据，并将该手势数据存储在驱动层的预设节点内；在黑屏手势事件上报时，并行执行驱动层读取手势数据，根据手势数据确定手势类型的操作；例如，驱动层获取该预设节点内的手势数据，对该手势数据作曲线拟合得到该黑屏手势最接近的手势类型，将该手势类型也作为手势数据存储在该预设节点内。其中，曲线拟合是一种数据处理方式，即用连续曲线近似地刻画或比拟平面上离散点所表示的坐标之间的函数关系。在应用层接收到黑屏手势事件时，按照设定周期检测该预设节点内的手势数据是否准备完成。在准备完成时，应用层由该预设节点内读取该手势数据。在该手势数据读取成功且有效时，根据该手势数据包含的手势坐标计算出黑屏手势轨迹，将该黑屏手势轨迹绘制在显示屏上进行显示。然后，应用层基于所读取的手势数据中的手势类型，打开与该手势类型对应的应用程序。
本文实施例提供的降低移动终端功耗的方案，通过在熄屏状态下，获取指纹识别模组检测到的指纹；在该指纹为非解锁指纹时，控制触摸芯片输出触摸感测控制信号至触控显示屏；根据该指纹来匹配用户具有操作权限的应用程序，获取该应用程序对应的黑屏手势集合；在检测到属于该黑屏手势集合的黑屏手势时，上报黑屏手势事件至应用层，以触发应用层执行该黑屏手势对应的操作。通过采用上述技术方案，可以避免触控显示屏持续工作造成的移动终端功耗升高的情况发生，同时，仅有与当前指纹匹配的应用程序对应的黑屏手势才会触发上报黑屏手势事件；进一步避免应用层基于无效的黑屏手势触发的黑屏手势事件，执行手势数据读取操作导致作无用功的情况发生；从而可以有效地降低移动终端的功耗，延长续航时间。
图3是本文实施例提供的另一种降低移动终端功耗的方法的流程图。如图3所示，该方法包括步骤301至步骤311。
在步骤301中，在熄屏状态下，获取指纹识别模组检测到的指纹。
在步骤302中，判断所述指纹是否为非解锁指纹，若是非解锁指纹，则执行步骤303，若不是非解锁指纹，执行步骤311。
将当前检测的指纹与预设的解锁指纹进行匹配。若匹配成功，则认为当前检测的指纹为是解锁指纹，进一步基于该解锁指纹，执行解锁操作；若匹配失败，则认为当前检测的指纹是非解锁指纹。
在步骤303中，根据所述指纹来匹配用户具有操作权限的应用程序，获取所述应用程序对应的黑屏手势集合，所述用户为具有所述指纹的用户。
在步骤304中，控制触摸芯片输出触摸感测控制信号至触控显示屏，检测黑屏手势输入。
驱动层控制触摸芯片输出触摸感测控制信号至触控显示屏，根据该触摸感测控制信号激活触控显示屏，使其进入检测黑屏手势的工作模式。从而，触控显示屏可以检测黑屏手势输入。
在步骤305中，判断在设定时间长度内是否检测到黑屏手势，若检测到黑屏手势，则执行步骤306；若没有检测到黑屏手势，执行步骤310。
其中，设定时间长度为移动终端对于黑屏手势检测操作的最长容忍时间。若在该设定时间长度内，未检测到作用于触控显示屏的黑屏手势，则判定不会有黑屏手势输入，从而不再检测黑屏手势输入。该设定时间可以由系统默认设置，也可以由用户根据实际需求自行设定。
在一实施例中，在输出触摸感测控制信号至触控显示屏时，启动计时器。在该计时器的计数值达到设定时间长度前，判断是否检测到黑屏手势输入，若检测到黑屏手势输入，则执行步骤306；若没有检测到黑屏手势输入，执行步骤310。
在步骤306中，判断所检测到的黑屏手势是否属于所述黑屏手势集合，若检测到的黑屏手势属于所述黑屏手势集合，则执行步骤307；若检测到的黑屏手势不属于所述黑屏手势集合，执行步骤308。
在步骤307中，上报黑屏手势事件至应用层，以执行所述黑屏手势对应的操作。
在步骤308中，提示用户黑屏手势输入错误，并记录所述黑屏手势输入错误的次数。
其中，提示用户黑屏手势输入错误的方式可以是移动终端振动设定次数和发出设定提示音中的至少一种。可以理解的是，上述列举出的提供用户黑屏手势输入错误的方式是举例而并非限定。
在检测到的黑屏手势不属于所述黑屏手势集合时，控制移动终端振动设定次数，以提示用户当前输入的黑屏手势错误。可以通过不同的振动次数表示不同的错误类型。例如，移动终端振动2次表明该黑屏手势不是预设的黑屏手势。移动终端振动4次表明用户对该黑屏手势对应的应用程序无操作权限等。
在检测到的黑屏手势不属于所述黑屏手势集合时，还启动一计数器，记录黑屏手势输入错误的次数。在检测到一次黑屏手势的错误输入时，控制计数器的计数值加1。
在步骤309中，判断所述次数是否超过设定次数阈值，若超过设定次数阈值，则执行步骤310；若没有超过设定次数阈值，执行步骤304。
其中，设定次数阈值可以是系统默认设置，还可以是由用户根据实际需求自行设置。
在黑屏手势的错误输入次数未超过设定次数阈值，则返回执行步骤304，以继续检测黑屏手势输入。
在步骤310中，控制触摸芯片停止输出所述触摸感测控制信号至所述触控显示屏。
在黑屏手势的错误输入次数超过设定次数阈值，驱动层控制触摸芯片不再向触控显示屏输出触摸感测控制信号，以使触控显示屏退出工作模式，从而，使触控显示屏处于休眠状态，避免为了维持触控显示屏工作而向其输入驱动电流，降低了移动终端的功耗。
在步骤311中，执行解锁操作。
在所检测的指纹为解锁指纹时，执行移动终端的解锁操作。
本文实施例提供的降低移动终端功耗的方案，通过在设定时间长度内未检测到黑屏手势输入，控制触摸芯片停止输出所述触摸感测控制信号至所述触控显示屏；在设定时间长度内检测到黑屏手势输入时，若该黑屏手势不属于所述黑屏手势集合，则提示用户黑屏手势输入错误，并记录所述黑屏手势输入错误 的次数；在所述次数超过设定次数阈值时，控制触摸芯片停止输出所述触摸感测控制信号至所述触控显示屏，使所述触控显示屏退出所述工作模式。通过采用上述技术方案，为用户输入黑屏手势设置最长容忍时间，及对输入的错误的黑屏手势设置最多容忍次数，可以有效地避免多次通过指纹识别模组激活触控显示屏，导致指纹识别模组的使用寿命受到影响的情况发生。
图4是本文实施例提供的又一种降低移动终端功耗的方法的流程图。如图4所示，该方法包括步骤401至步骤410。
在步骤401中，在熄屏状态下，获取指纹识别模组检测到的指纹。
在熄屏状态下，使指纹识别模组和压力传感器处于工作状态。其中，该指纹识别模组设置为检测用户输入的指纹，指纹包括指纹图案。压力传感器用于检测用户输入指纹时的按压压力。若用户手指接触指纹识别模组，通过压力传感器检测用户输入所述指纹时的按压压力。
在步骤402中，判断指纹图案与预先存储的指纹模板是否匹配成功，若匹配成功，则执行步骤403；若没有匹配成功，执行步骤404。
在移动终端内预先存储用户录入的指纹，作为指纹模板。可以根据检测到的指纹是否属于该指纹模板，使移动终端分别处于用户模式和访客模式。
在步骤403中，确定移动终端处于用户模式。
其中，用户模式下可以根据用户输入的指纹确定用户具有操作权限的应用程序。
在步骤404中，确定移动终端处于访客模式。
其中，访客模式下用户仅能操作预先设定的应用程序。例如，预先设定的应用程序可以是打开摄像机或手电筒应用程序等不涉及机主隐私的应用程序。
在步骤405中，获取用户输入所述指纹时的按压压力。
获取该压力传感器检测到的用户输入指纹时的按压压力。
在一实施例中，还可以启动摄像头获取用户的生物特征信息，将所述生物特征信息与预设信息模板进行匹配。从而根据匹配结果判定是否控制触摸芯片输出触摸感测控制信号至所述触控显示屏。其中，生物特征信息可以是面部特征信息等。若在检测到指纹输入时，通过摄像头检测到面部特征信息，则认为本次指纹输入不是误操作，则可以控制触摸芯片输出触摸感测控制信号至触控显示屏。
在步骤406中，判断所述按压压力是否属于预设压力区间，若属于预设压力区间，则执行步骤407；若不属于预设压力区间，执行步骤410。
其中，预设压力区间可以由系统默认配置，还可以由用户自行设置。例如，移动终端为用户提供压力区间校正功能。在用户进入该压力区间校正功能时，提示用户多次正常输入指纹，记录各次指纹输入操作对应的按压压力，作为预 设压力区间。
将当前用户输入指纹时的按压压力，分别与该预设压力区间的最小值与最大值进行比较。若该按压压力小于该预设压力区间的最小压力值或大于该预设压力区间的最大压力值，则确定该按压压力不属于预设压力区间。若该按压压力大于该预设压力区间的最小值且小于该预设压力区间的最大压力值，则确定该按压压力属于该预设压力区间。
在步骤407中，控制触摸芯片输出触摸感测控制信号至触控显示屏。
在当前用户输入指纹时的按压压力属于预设压力区间时，认为当前指纹输入操作不是误操作，控制触控显示屏激活，以检测黑屏手势。
在步骤408中，根据所述指纹来匹配用户具有操作权限的应用程序，获取所述应用程序对应的黑屏手势集合，所述用户为具有所述指纹的用户。
在步骤409中，在检测到属于所述黑屏手势集合的黑屏手势时，上报黑屏手势事件至应用层，以执行所述黑屏手势对应的操作。
在步骤410中，判定为发生一次误触摸，不输出触摸感测控制信号至触控显示屏。
在当前用户输入指纹时的按压压力不属于预设压力区间时，认为当前指纹输入操作是一次误操作，不输出触摸感测控制信号至触控显示屏。
本文实施例提供的降低移动终端功耗的方案，通过在控制触摸芯片输出触摸感测控制信号至触控显示屏之前，获取用户输入所述指纹时的按压压力；若所述移动终端处于用户模式，则判断所述按压压力是否属于预设压力区间；根据判断结果判定是否控制触摸芯片输出触摸感测控制信号至所述触控显示屏；若所述移动终端处于访客模式，则执行控制触摸芯片输出触摸感测控制信号至所述触控显示屏的操作。通过采用上述技术方案，可以有效地避免因误触指纹识别模组而错误的激活触控显示屏，导致移动终端的功耗增大的情况发生。
图5是本文实施例提供的降低移动终端功耗的装置的结构框图。该装置可有软件和/或硬件实现，一般集成在移动终端中。如图5所示，该装置可以包括指纹获取模块510，触摸芯片控制模块520，手势集合获取模块530以及手势事件上报模块540。

手势事件上报模块540，设置为在检测到属于所述黑屏手势集合的黑屏手势 时，上报黑屏手势事件至应用层，以执行所述黑屏手势对应的操作。
本实施例的技术方案提供一种降低移动终端功耗的装置，通过采用上述技术方案，可以避免触控显示屏持续工作造成的移动终端功耗升高的情况发生，同时，仅有与当前指纹匹配的应用程序对应的黑屏手势才会触发上报黑屏手势事件；进一步避免应用层基于无效的黑屏手势触发的黑屏手势事件，执行手势数据读取操作导致作无用功的情况发生；从而可以有效地降低移动终端的功耗，延长续航时间。

以及，还包括：
模式切换模块，设置为在控制触摸芯片输出触摸感测控制信号至触控显示屏之后，若在设定时间长度内未检测到黑屏手势输入，则控制触摸芯片停止输出所述触摸感测控制信号至所述触控显示屏，使所述触控显示屏重新进入非工作模式。
