图1是本申请实施例提供的终端设备的示意性结构图。以图1所示的手机为例对本申请所适用的终端设备进行具体说明。
示例性地，如图1所示，本申请实施例中的电子设备01可以为手机100。下面以
手机100为例对实施例进行具体说明。应该理解的是，图1所示手机100仅是电子设备01的一个范例，并且手机100可以具有比图中所示出的更多的或者更少的部件，可以组合两个或更多的部件，或者可以具有不同的部件配置。图中所示出的各种部件可以在包括一个或多个信号处理和/或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。
在本申请实施例中，手机100具体可以包括：一个或多个处理器180、射频(radio frequency，RF)电路110、存储器120、输入单元130、显示单元140(例如触摸屏)、一个或多个传感器150、音频电路160、无线保真(wireless fidelity，WiFi)模块170、电源系统190等部件。这些部件可通过一根或多根通信总线或信号线进行通信。本领域技术人员可以理解，图1中示出的手机结构仅为示例而非限定，图1中示出的硬件结构并构成对手机100的限定，手机100还可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图1对手机100的各个部件进行具体介绍。
处理器180是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器120内的应用程序，以及调用存储在存储器320内的数据和指令，执行手机100的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器180可包括一个或多个处理单元；处理器180还可以集成应用处理器和调制解调处理器；其中，优选的，处理器180可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器180中。举例来说，处理器180可以是华为技术有限公司制造的麒麟980芯片。在本申请实施例中，上述处理器180可以包括检测单元，用于检测对应的触摸感应区之间的电势差的变化。
并且，该处理器180可以作为其他处理单元的实现元件，执行与处理单元相同或相似的功能。
在本申请其他一些实施例中，上述处理器180还可以包括AI芯片。AI芯片的学习和处理能力包括图像理解能力、自然语言理解能力和语音识别能力等。AI芯片可以使得手机100具有更好的性能、更长的续航时间以及更好的安全性和隐私性。例如，若手机100通过云端处理数据则需要数据上传处理后再返回结果，在现有技术条件下效率很低。若手机100本地端具有较强的AI学习能力，那么手机100就不需要把数据上传到云端，直接在本地端处理即可，因而可以在提高处理效率的同时，提高数据的安全性和隐私性。
在本申请实施例中，控制单元就相当于手机的处理器180，执行本申请实施例的控制屏幕开闭的方法。

在本申请一些实施例中，传感器150还可以包括指纹传感器。例如，可以在手机100的背面(例如后置摄像头的下方)配置指纹传感器，或者在手机100的正面(例如触摸 面板131的下方)配置指纹传感器。另外，也可以通过在触摸面板131中配置指纹传感器来实现指纹识别功能，即指纹传感器可以与触摸面板131集成在一起来实现手机100的指纹识别功能。在这种情况下，该指纹传感器可以配置在触摸面板131中，可以是触摸面板131的一部分，也可以以其他方式配置在触摸面板131中。另外，该指纹传感器还可以被实现为全面板指纹传感器，因此，可以把触摸面板131看成是任何位置都可以进行指纹采集的一个面板。该指纹传感器可以将采集到的指纹发送给处理器180，以便处理器180对该指纹进行处理(例如指纹验证等)。本申请实施例中的指纹传感器可以采用任何类型的感测技术，包括但不限于光学式、电容式、压电式或超声波传感技术等。

为了便于理解，示例性的给出了部分与本申请实施例相关概念的说明以供参考。
霍尔(HALL)传感器是根据半导体的霍尔效应制作的一种器件，霍尔效应是磁电效应的一种。霍尔效应从本质上讲是运动的带电粒子在磁场中收到洛伦兹力的作用引起的偏转，对于半导体而言，这种偏转导致垂直电流和磁场的方向上产生正负电荷的聚积，从而形成附加的横向电场。
目前，在现有的翻盖手机中，广泛应用霍尔器件来判断手机的张开或者闭合的状态。具体的工作原理是在磁场作用下，利用磁场信号来控制一种线路开关器件，直接产生通与断的作用。霍尔传感器是一种电子元件，其外型封装和三极管非常相似，具体由霍尔元件、放大器、施密特电路以及集电极开路输出三极管组成，当磁场作用于霍尔元件时产生一个微小的霍尔电压，经放大器放大和施密特电路后使三极管导通输出低电平，而没有磁场作用的时候(即翻盖打开后)三极管截止输出为高电平。当手机的翻盖打开后，没有磁场力的作用，三极管输出为高电平，当手机翻盖在闭合过程中，磁场作用产生微小电压，输出低电平。
在实际运用中，霍尔传感器的导通与否完全受到手机中央处理器(central processing unit，CPU)输出的霍尔高电平信号控制，电源则来自于电池。当翻盖合上时，在磁场作用下，产生霍尔电压，经过三极管导通后，，从霍尔传感器的引脚输出低电平。如果是在通话后则作为“挂机”信号送给CPU挂机。
上述介绍了终端利用霍尔器件来判断折叠手机的张开或者闭合的状态，但是霍尔器件占用空间较大，且成本较高，不利于终端的空间优化和成本优化；而且，霍尔器件需要安 装在翻盖上的磁体产生磁场，会对天线的射频产生干扰问题。本申请针对未来的可折叠屏终端设备，提出一种新的检测方案，替代霍尔器件实现对终端设备张开或者闭合状态的检测，降低成本的同时进行空间优化、提高用户体验。
应理解，本申请提供的检测方法应用于配置了电容屏的折叠屏终端设备，本申请将以手机为例进行详细的介绍。
首先，对电容屏进行简单的说明。电容屏是借助于电流感应进行工作的复合玻璃屏(塑料屏)，触摸屏的感应层是由具有透明导电的材料实现互相感应电容或对地感应电容，根据手指触摸时的电容变化量来判断触摸位置和触摸方式。导电材料通常是氧化铟锡(indium tin oxide，ITO)或者纳米银等，并将其附着在基材上(玻璃、PET、PI等等材料)。电容屏要实现多点触控，可以增加电容的电极数量。
具体地，将终端的屏幕进行分块，在每一个分块区域里设置交互的电容模块，每一组电容模块都是独立工作或与周围电容模块组合工作，所以电容屏就可以独立检测到各区域的触控情况，进行处理后，简单地实现多点触控。当用户触摸电容屏时，由于人体电场，用户手指和电容屏的工作面之间形成一个耦合电容，当手指点击电容屏，手指会从电容屏的触点吸收小量的电流(例如几微安)，造成电容屏四个角落设置的电极的压降，从而解析出触摸点的位置坐标。图2是本申请提供的一例手机配置的触摸感应区的示意图，如图2所示的手机201，沿着折叠轴203将可折叠终端分为两个折叠区，将该可折叠手机的上半部分202称为“第一区域”，将可折叠手机的下半部分204称为“第二区域”。此外，可以为终端配置多个触摸感应点205，本申请中将触摸感应点所在的区域称为“触摸感应区”、“触摸区”或者“感应区”，例如第一触摸感应区和第二触摸感应区。在本申请实施例的描述中，电容屏的对应的触摸感应区之间的电势差将以一组对应的触摸感应点之间的电势差为例进行说明。应理解，一个触摸感应区还可以包括多个触摸感应点，本申请对此并不限定。
应理解，图2中只示出了两对触摸感应点，触摸感应点1和触摸感应点3为设置在第一区域202上的感应区域，触摸感应点2和触摸感应点4为设置在第二区域204上的感应区域。其中，触摸感应点1和触摸感应点2为手机201的一对相互对应的触摸感应区，当手机201折叠状态，即，触摸感应点1在第二区域204上的投影和触摸感应点2重叠，换言之，屏幕折叠闭合态时，触摸感应点1和触摸感应点2是重叠的。同理，触摸感应点3和触摸感应点4也是一对相互感应的触摸感应区。此外，触摸感应点205可以理解为一种导体，类似于上述介绍的ITO，能够接收手机的充放电，每一对触摸感应点之间的容值可以随着手机充放电或者距离的变化而变化。
还应理解，触摸感应点之间的电容值可以理解为两个触摸感应点之间的电势差。具体地，在电路学里，在一定电势差(1U)下，电容器的存电荷的能力，称为电容(capacitance)，标记为C。采用国际单位制，电容的单位是法拉(farad)，简称法；标记为F。电容的符号是C，在真空条件下，可以根据以下公式(1)得到电容C。
C＝εS/d＝εS/4πkd＝Q/U(1)
其中，ε是一个电常数，S为电容极板的一个面的面积，d为电极之间的距离，k则是静电力的常量。由以上公式(1)可得，电容和电极之间的距离d成反比，随着电极之间距离的增大而增大。应理解，在本申请实施例中，随着触摸感应点之间距离的变化，手 机可以通过检测触摸感应点之间的电容值的变化来判断是否要点亮或者熄灭屏幕；换言之，手机可以通过检测触摸感应点之间的电势差的变化来判断是否要点亮或者熄灭屏幕。
应理解，这里点亮屏幕或者熄灭屏幕可以包括多种可能的应用场景，图3是本申请实施例提供的几例可能的点亮屏幕的示意图。例如，图(3-a)所示的示意图，点亮屏幕可以是从熄灭屏幕的锁屏状态到解锁页面；或者图(3-b)所示的示意图，点亮屏幕可以是从熄灭屏幕的锁屏状态到点亮屏幕的锁屏状态；又或者，手机为不加锁状态，则点亮屏幕可以是从熄灭的锁屏状态直接到手机的主页面状态。熄灭屏幕也可以对应各种不同的场景，例如手机从打开到闭合的过程中，手机熄灭可以是熄灭并锁屏，或者只是熄灭并未锁屏，用户可以通过触摸等操作唤醒屏幕，而不需要再讲过解锁，直到手机折叠完全闭合再进入锁屏状态。本申请对此并不限定。
此外，还应理解，在本申请中，触摸感应点的分布是第一区域202和第二区域204内对应排布的，但是具体在每一个区域内，触摸感应点的分布不限制在点状分布、带状分布或者其他形状的分布，本申请以点状分布为例，描述在手机闭合和开启过程中一组触摸感应点之间的电容变化，本申请对触摸感应点的分布规律、排布形状、数量不作限定。
在具体的实现过程中，终端可以通过测试多组触摸感应点之间的电容值的变化来判断终端当前的开闭状态，例如折叠或者闭合过程。或者，终端可以多组触摸感应点之间的共有的电容值的变化规律来判断终端当前的开闭状态，例如，通过设置三组触摸感应点，触摸感应点1和触摸感应点2、触摸感应点3和触摸感应点4、触摸感应点5和触摸感应点6，当状态1时，触摸感应点1和触摸感应点2之间电容值为0.8V，触摸感应点3和触摸感应点4之间电容值为0.9V，触摸感应点5和触摸感应点6之间电容值为1.0V；当状态2时，触摸感应点1和触摸感应点2之间电容值为0.4V，触摸感应点3和触摸感应点4之间电容值为0.45V，触摸感应点5和触摸感应点6之间电容值为0.5V。终端判断从状态1到状态2的过程中，连续三组触摸感应点的变化规律跟预设的规律一致是，也可以判断终端的状态。应理解，本申请对以上所列举的多组触摸感应点的排布规律并不限定，例如可以是点状、带状、条状，对触摸感应点的组数也不限定。在一种可能的实现方式中，所述第一触摸感应区与所述第一轴之间的距离大于或等于第三阈值，所述第二触摸感应区与所述第一轴之间的距离大于或等于所述第三阈值。这里设置第三阈值，可以保证一组触摸感应点之间的电势差的变化的灵敏度。可以配置使触摸感应点距离折叠轴较远，因为随着折叠角度减小，如果触摸感应点距离折叠轴较近，则会造成两个触摸感应点也是无限接近的状态，不利于电势差的测量。
例如，在配置多组触摸感应点的过程中，优选地将触摸感应点配置在电容屏的上下边沿位置，如图(2-a)中所示的触摸感应点1、2、3和4。此种情况下，触摸感应点距离折叠轴的距离较大，有利于电势差变化的敏感度，方便手机进行电势差的检测。
图4是本申请实施例提供的一种控制屏幕开闭的方法的示意流程图。应理解，该方法可以应用于具有可折叠电容屏的电子设备，所述可折叠电容屏能够绕第一轴折叠，所述可折叠电容屏包括分别位于所述第一轴两侧的第一部分和第二部分，在所述第一部分中设置有第一触摸感应区，所述第二部分中设置有第二触摸感应区，所述电子设备能够向所述第一触摸感应区施加第一电势，能够向所述第二触摸感应区施加第二电势。所述方法包括S401-S406，下面对每个步骤进行详细的介绍。
S401，开始。手机为运行状态，例如可进行规律性的充放电。
S402，手机的控制单元控制电源模块向第一触摸感应区施加第一电势，能够向第二触摸感应区施加第二电势。即，向手机电容屏中设置的触摸感应点进行充放电，向对应的一对触摸感应点施加电势。
S403，检测装置检测所述第一触摸感应区和所述第二触摸感应区之间的电势差。
S404，控制装置判断第一触摸感应区和所述第二触摸感应区之间的电势差的范围，并根据该第一触摸感应区和所述第二触摸感应区之间的电势差所处的范围点亮或者熄灭该可折叠电容屏。
S405，在所述可折叠电容屏处于熄灭状态时，当所述电势差小于或等于预设的第一阈值时，所述控制装置点亮所述可折叠电容屏。
S406，在所述可折叠电容屏处于点亮状态时，当所述电势差大于或等于预设的第二阈值时，所述控制装置熄灭所述可折叠电容屏。
应理解，在手机所处的不同状态中，该第一触摸感应区和所述第二触摸感应区之间的电势差是变化的，下面将具体结合手机从折叠关闭到打开的过程，和从打开到折叠闭合状态的过程进行详细的描述。
图5是本申请实施例提供的一例手机由折叠闭合态到开启过程的示意图。如图5所示，手机从折叠状态逐渐打开的过程中，可以分别包括图(5-a)示出的第一区域202和第二区域204之间的角度小于90°，图(5-b)示出的第一区域202和第二区域204之间角度为90°，图(5-c)示出的第一区域202和第二区域204之间角度大于90°三种情况。此外，图5中黑色实心点表示本申请的触摸感应点，一对触摸感应点之间的距离为d，应理解，这里d可以是两个触摸感应点的几何中心之间直线的距离。
可选地，手机通过芯片控制，对电容屏进行规律性的充放电。可选地，手机对电容屏按照正弦波曲线进行规律性的充放电，例如，频率f＝90KHz。本申请对此并不限定。
对于手机芯片控制的规律性充放电，会在两个触摸感应点的区域分别聚集电荷，例如，第一区域202经过手机的充电后，聚集大量的正电荷，第二区域204经过手机的充电后，聚集大量的负电荷，正负电荷之间之间形成电势差，即两个触摸感应点所在区域之间形成感应电场，类似于平行板之间的电场。图6是本申请实施例提供的一例触摸感应点之间电场示意图。如图6所示，对于手机从折叠状态开启到角度α(α<90°)时，两个触摸感应区之间对应的距离为d，两个触摸感应区之间的电势差为U，电场强度为E，则d、U、E之间满足以下公式(2)：
E＝U/d        (2)
图7是本申请实施例提供的一例触摸感应点之间电势差变化示意图。下面结合图7和图5，列举在图5示出的三种变化过程中，手机可以随时检测一组触摸感应点之间的电势差变化具体列举如下：
场景一
如图(5-a)示出的第一区域202和第二区域204之间的角度α的变化范围为0°≤α<90°时，对应地，一对触摸感应点之间的距离d从0开始逐渐增大，设当α＝90°时，一对触摸感应点之间的距离为d max。随着d的逐渐增大，两个触摸感应点之间的电势差的变化如图6所示，即两个触摸感应点之间的电势差U从U max逐渐开始降低，直到d增大到d max，U 降低为0。
为手机设置第一阈值U 0，当所述电势差U小于或等于预设的第一阈值U 0时，点亮手机的可折叠电容屏。这里预设的第一阈值是电势差时，当检测到两个触摸感应点之间的电势差小于或等于该第一阈值U 0时，点亮手机屏幕。
在一种可能的实施方式中，为手机设置第二阈值d 0，当两个触摸感应点之间的距离大于或等于预设的第二阈值d 0时，点亮手机的可折叠电容屏。这里预设的第二阈值是两个触摸感应点之间的距离，当检测到两个触摸感应点之间的距离大于或等于该第二阈值d 0时，点亮手机屏幕。
应理解，以上两种方式中的任一种都可以用于点亮电容屏的判定，或者，两种方法也可以同时用于点亮电容屏的判定，本申请对此并不限定。
场景二
如图(5-b)示出的第一区域202和第二区域204之间角度为90°时，以及(5-c)示出的第一区域202和第二区域204之间角度大于90°时，对应地，一对触摸感应点之间的距离大于或等于d max。从d max开始，随着d的逐渐增大，如图7中所示的平直线，两个触摸感应点之间的电势差为0或者无限接近于0。
通过上述触摸感应点所判断出的手机当前形态反馈给手机系统软件进行系统/屏幕的开启。
以上介绍了手机从折叠闭合的熄灭状态逐渐到打开过程中，触摸感应点之间距离和电势差的变化情况，同时，提供了一种控制屏幕点亮的方法，该方法能够通过手机的可折叠的电容屏来判断手机的折叠状态，进行点亮电容屏的动作，控制点亮电容屏的时机，能够提供一种便捷的判定方式，减少电源键的使用频率，延长电源键寿命；而且该方法利用手机规律性充放电，具有可识别性，且不会被误触发。
图8是本申请实施例提供的一例手机由开启到折叠闭合态过程的示意图。如图8所示，手机从开启状态逐渐折叠闭合的过程中，可以分别包括图(8-a)示出的第一区域202和第二区域207之间的角度大于90°，图(8-b)示出的第一区域202和第二区域204之间角度为90°，图(8-c)示出的第一区域202和第二区域204之间角度小于90°三种情况。同理，图8中黑色实心点表示本申请的触摸感应点，一对触摸感应点之间的距离为d，应理解，这里d可以是两个触摸感应点的几何中心之间直线的距离。
图9是本申请实施例提供的一例触摸感应点之间电势差变化示意图。下面结合图9和图8，列举在图8示出的三种变化过程中，手机可以随时检测一组触摸感应点之间的电势差变化具体列举如下：
场景一
如图(8-a)示出的第一区域202和第二区域204之间的角度大于90°时，如图(8-b)示出的第一区域202和第二区域204之间角度为90°时，对应地，一对触摸感应点之间的距离d从D开始逐渐减小，设当α＝90°时，一对触摸感应点之间的距离为d min。随着d的逐渐减小，两个触摸感应点之间的电势差的变化如图9所示，即两个触摸感应点之间的电势差U为0或无限接近于0。
场景二
如图(8-c)示出的第一区域202和第二区域204之间的角度小于90°时，对应地，一 对触摸感应点之间的距离d从d min开始逐渐减小，直到减小到0。设当α＝90°时，一对触摸感应点之间的距离为d min。随着d的逐渐减小，两个触摸感应点之间的电势差的变化如图9所示，即两个触摸感应点之间的电势差从0开始逐渐增大，直到增大到U max。
为手机设置第一阈值U 0，当所述电势差U小于或等于预设的第一阈值U 0时，即0<U<U 0时，点亮手机的可折叠电容屏。这里预设的第一阈值是电势差时，当检测到两个触摸感应点之间的电势差小于或等于该第一阈值U 0时，点亮手机屏幕。换言之，当所述电势差U大于预设的第一阈值U 0时，即U>U 0时，熄灭手机的可折叠电容屏。
在一种可能的实施方式中，为手机设置第二阈值d 0，当两个触摸感应点之间的距离大于或等于预设的第二阈值d 0时，点亮手机的可折叠电容屏。这里预设的第二阈值是两个触摸感应点之间的距离，当检测到两个触摸感应点之间的距离大于或等于该第二阈值d 0时，点亮手机屏幕。换言之，当所述两个触摸感应点之间的距离d小于预设的第二阈值d 0时，即d<d 0时，熄灭手机的可折叠电容屏。
应理解，以上所涉及的点亮手机的可折叠电容屏还可以是手机一直处于点亮状态，当满足这个电势差范围时，不熄灭手机的可折叠电容屏，继续保持点亮状态。
还应理解，以上两种方式中的任一种都可以用于熄灭电容屏的判定，或者，两种方法也可以同时用于熄灭电容屏的判定，本申请对此并不限定。通过上述触摸感应点所判断出的手机当前形态反馈给手机系统软件进行系统/屏幕的关闭。
以上介绍了手机从打开逐渐到折叠闭合的熄灭状态的过程中，触摸感应点之间电势差的变化情况判断手机的开闭状态；同时，提供了一种控制屏幕熄灭的方法，该方法能够通过手机的可折叠的电容屏来判断手机的折叠状态，控制熄灭电容屏的时机，能够提供一种便捷的判定方式，减少电源键的使用频率，延长电源键寿命；而且该方法利用手机规律性充放电，具有可识别性，且不会被误触发。
综上所述，本方案可以通过在手机电容屏上设置触摸感应点，并不断检测触摸感应点之间电势差的变化情况，通过触摸感应点之间电势差的变化判断出的手机当前形态，并将判断出的手机当前形态反馈给手机系统软件进行系统/屏幕的开启或关闭。该方法能够实现一种便捷的判定方式，减少电源键的使用频率，延长电源键寿命；能够节省外围器件，如霍尔器件，降低成本；此外，还可以节省霍尔器件的摆放空间和减少其对天线的影响，设计出更好看的外观。
