具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
当本发明实施例提及“第一”、“第二”等序数词时，除非根据上下文其确实表达顺序之意，应当理解为仅仅起区分的作用。
图1是根据本发明的示例性实施例的电子设备100的框图。如图1中所示，电子设备100包括与总线101耦合的显示单元102、测量单元103、切换单元104、存储单元105和缩放单元106。图1示出具有各种组件的电子设备100，但是应当理解的是，电子设备100的实现并不一定需要图示的所有组件，可以通过更多或更少的组件来实现电子设备100，在本发明中，电子设备100具有柔性显示屏110。
在下文中，将会解释上面的组件中的每一个。
柔性显示屏110具有可弯曲的结构并且由能够被弯曲的材料制成。柔性显示屏110是指可以弯曲、弯钩(crook)、折叠或者像纸那样卷起、同时具有非柔性平板显示装置的显示特性的装置。柔性显示屏110可选的由柔性基板、驱动 器、显示面板和保护层构成。柔性显示屏110可以被制造在柔性基板上。具体地说，柔性基板可以通过使用可通过外部压力变形的塑料(例如，高分子膜)来实现。
利用塑料实现的柔性基板具有这样的结构，该结构通过在基膜的相对表面上进行防护涂敷而形成。该基膜可以通过使用各种树脂来实现，所述树脂例如聚酰亚胺(polyimide，PI)、聚碳酸酯(polycarbonate，PC)、聚对苯二甲酸乙二醇酯(polyethyleneterephtalate，PET)、聚醚砜(polyethersulfone，PES)、聚萘二甲酸乙二酯(polythylenenaphthalate，PEN)和纤维增强塑料(fiber reinforced plastic，FRP)。
柔性基板也可以由其它柔性材料而不是塑料来形成，其他柔性材料例如薄的玻璃或者金属箔。
驱动器驱动柔性显示屏110的显示面板。具体地说，驱动器向显示面板的多个像素施加驱动电压，并且可以通过使用硅TFT、低温多晶硅(LTPS)TFT或者有机TFT(OTFT)来实现。驱动器也可以根据显示面板的形式以各种形式实现。例如，该显示面板可以由包括多个像素单元的有机发光物质以及覆盖该有机发光物质的相对表面的电极层构成。在这种情况下，该驱动器可以包括与显示面板的多个像素单元对应的多个晶体管。控制器向每个晶体管的栅极施加电信号并且控制连接到晶体管的像素单元发光，从而实现图像显示。
除了有机发光二极管(OLED)之外，显示面板也可以通过使用例如场致发光显示器(EL)、电泳显示器(EPD)、电致变色显示器(ECD)、液晶显示器(LCD)、有源矩阵LCD(AMLCD)或者等离子体显示面板(PDP)来实现。
除上述构造之外，柔性显示屏110还可以通过使用电子纸(e-paper)来实现，电子纸可以使用利用扭转球或者胶囊的电泳来改变图片或者文本。
如果柔性显示屏110由透明材料形成的元件构成，则该柔性显示屏110可以被实现为可弯曲且透明的显示装置。
柔性显示屏110具有至少一个显示表面，即柔性显示屏可以在相对的两个表面中进行显示。
根据电子设备100的配置情况，可以在数目上以两个或者更多个显示屏实现柔性显示屏。例如，多个显示屏可以被一体化地或者单独地布置在一个表面上，或者被布置在不同的表面上。
同时，包括柔性显示屏110的根据示例实施例的电子设备100可以包括未图示的壳体，该壳体包围柔性显示屏。考虑到柔性显示屏的特性，壳体可以被配置成能够与柔性显示屏一起被外力弯曲。
显示单元102可以显示在电子设备100中处理的信息。例如，当电子设备100是处于电话呼叫模式中时，显示单元102可以显示与呼叫相关联的用户界面(UI)或者图形用户界面(GUI)。
特别的，显示单元102，用于当电子设备100处于智能手机模式时，在未发生弯曲的柔性显示屏110上显示n个应用的图标，n为大于1的整数；显示单元102，还用于当电子设备处于可穿戴模式时，在柔性显示屏110的设定区域上显示m个应用的图标，所述设定区域由弯曲线(将在下文中详细描述)确定，所述设定区域可以为柔性显示屏110的全部显示区域，也可以是柔性显示屏的全部显示区域中的一部分。
所述设定区域中显示的内容，可以是图像、应用图标、应用的功能界面等。
所述弯曲线指连接弯曲区域上发生最大程度弯曲的点的直线，m为小于或等于n的整数。
测量单元103用于测量柔性显示屏110的弯曲信息。柔性显示屏110的弯曲信息可以包括由于柔性显示屏110的弯曲能够感测的各种信息。具体地说，测量单元103可以识别弯曲/折叠位置、弯曲/折叠方向、弯曲/折叠角度、弯曲/折叠的程度、弯曲/折叠速度、进行弯曲/折叠的次数、弯曲/折叠产生时间、和弯曲/折叠保持时间。测量单元103可以包括弯曲感测器或压力感测器(将在下文中详细讨论)。
可选的，测量单元103由一个或多个传感器元件构成，所述一个或多个传感器元件可为压力传感器、红外传感器、超声波传感器、电磁场传感器、电容传感器、接触传感器和接近传感器，所述多种类型的传感器可以根据需要进行 任意组合，只要能够达到测量弯曲信息的目的即可。一个或多个传感器元件可以设置在柔性显示屏110的上表面和/或下表面。作为传感器的一种示意性举例，测量单元103可由多个在屏幕上下表面分别设置的应变片构成。
本发明中所述的弯曲线指代弯曲区域上发生最大程度弯曲的点。当弯曲感测器由多个相互分离的应变片实现时，弯曲点以每个应变片所在的点表示，连接输出最大电阻值的应变片所在的点而构成的虚拟线即为弯曲线。
测量单元103可以通过从弯曲感测器输出的电阻值的分布或压力感测器感测到的压力的变化来识别弯曲的程度，所述弯曲的程度还可以表示为柔性显示屏的两个边缘由于弯曲而相互靠近的程度，例如，测量单元103可以测量柔性显示屏的上下两端的距离，从而识别柔性显示屏110的弯曲程度。
测量单元103可以感测弯曲状态的变化。具体地说，测量单元103可以识别弯曲/折叠位置的变化，弯曲/折叠方向的变化，弯曲/折叠角度的变化，以及弯曲/折叠程度的变化。
切换单元104基于测量单元103感测到的弯曲来切换电子设备100的工作模式，例如，如果测量单元103感测到的弯曲/折叠操作满足预先确定的条件，则切换单元104可以将电子设备100由智能手机模式切换为可穿戴模式，或者将电子设备100由可穿戴模式切换为智能手机模式。
存储单元105，用于存储电子设备100的各种工作模式，以及与各种工作模式相关的内容，与工作模式相关的内容包括柔性显示屏上显示的内容、对应用进行的特定操作、情景模式信息等。
例如，电子设备100处于智能手机模式时采用第一情景模式，处于可穿戴模式时采用第二情景模式，在存储单元105中分别存储第一情景模式的信息和第二情景模式的信息。在第一情景模式中，来电提醒使用第一音量大小的铃声1，新短信使用第二音量大小的铃声2，提示音使用第三音量大小的铃声3。在第二情景模式中，来电提醒使用第一振动强度的振动1，新短信使用第二振动强度的振动2，提示音使用第三振动强度的振动3。
可以理解的是，上述对第一和第二情景模式的说明仅为示意性举例，所述 第一和第二情景模式可以分别包括音量大小和/或振动强度的一定组合，例如第一情景模式可为：来电提醒使用第一音量大小的铃声1和第一振动强度的振动1，新短信使用第二振动强度的振动2，提示音使用第三音量大小的铃声3。第一和第二情景模式有本领域技术人员熟知的多种实现方式，在此不再一一说明。
存储单元105可以存储由下文所述的处理器执行的处理和控制操作的软件程序，或者可以临时存储输入或输出的数据(例如，电话本、消息、静止图像、视频等)。
使用任何类型的适当的存储介质可以实现存储单元105，该存储介质包含闪存型、硬盘型、微型多媒体卡、存储卡(例如，SD或者DX存储器等)、随机存取存储器(RAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)、电可擦可编程只读存储器(EEPROM)、可编程只读存储器(PROM)、磁存储器、磁盘、光盘等等。而且，电子设备100可以与因特网上的、执行存储单元105的存储功能的网络存储装置有关地操作。
缩放单元106用于对应用的图标尺寸进行放大或缩小。例如，缩放单元缩小可穿戴模式时显示的应用图标的尺寸，使应用图标的尺寸与可穿戴模式时的显示面积相适应。
在可穿戴模式中，电子设备100作为智能手表或智能手环等可穿戴设备使用，此时，在显示单元102中显示与可穿戴设备相关的应用图标，与可穿戴设备相关的应用图标包括但不限于：计步器、心率计、时钟、健康、海拔高度表或睡眠统计等。
电子设备100还包括处理器，处理器是电子设备100的控制中心并提供排序和处理设施以执行指令、执行中断操作、提供定时功能和许多其它功能。可选地，处理器包括一个或多个中央处理器(CPU)，可选地，电子设备100包括一个以上的处理器。处理器可以是单核(单CPU)处理器或多核(多CPU)处理器。本文所使用的术语“处理器”指一个或多个用于处理计算机程序指令等数据的设备、电路和/或处理内核。
处理器可以执行存储在数据存储装置中的程序代码。可选地，在数据存储 装置的存储介质中存储的程序代码可以被复制到存储单元中以便处理器执行。
电子设备100还包括控制单元，用于关闭柔性显示屏的一部分或全部，例如当电子设备处于可穿戴模式时，控制单元可以关闭柔性显示屏上除设定区域之外的其它区域。
电子设备100还包括通信接口，用于直接或通过外部网络与另一设备或系统进行通信。
可选地，电子设备100还包括输入设备(未图示)。输入设备与处理器耦合，并能够以一种或多种方式接收用户的输入。输入设备的示例包括鼠标、键盘、触摸屏设备、传感设备等等。
电子设备100的上述元件可通过数据总线、地址总线、控制总线、扩展总线和本地总线等总线301中的任一或任意组合互相耦合。
本文描述的各种实施方式可以例如利用软件、硬件或其任何组合在计算机可读介质或其类似介质中实现。
对于硬件实现来说，通过使用被设计为执行在此描述的功能的专用集成电路(ASIC)、数字信号处理器(DSP)、数字信号处理装置(DSPD)、可编程逻辑器件(PLD)、现场可编程门阵列(FPGA)、中央处理器(CPU)、通用处理器、微处理器、电子单元中的至少一个，可以实现在此描述的实施例。在一些情况下，可以通过处理器本身实现此实施例。
对于软件实现，可以通过单独的软件模块来实现在此描述的诸如程序或者功能的实施例。每个软件模块可以执行在此描述的一个或者多个功能或者操作。
通过以任何适合的编程语言所编写的软件应用能够实现软件代码。软件代码可以被存储在存储单元中并且通过处理器执行。
图2是根据示例实施例的感测柔性显示屏的弯曲信息的示意图。
柔性显示屏110可以通过外部压力来弯曲并且其形状可以被改变。术语“弯曲(bending)”包括正常弯曲、折叠和卷起。“正常弯曲”是指柔性显示屏沿线弯曲的状态。“折叠”是指柔性显示屏沿线折叠的状态。折叠和正常弯曲可以通过弯曲程度来相互区分。例如，如果弯曲大于预定弯曲角度，则该弯曲被称为 折叠，并且如果弯曲小于预定弯曲角度，则该弯曲被称为正常弯曲。
“卷起”是指柔性显示屏被卷起的状态。该卷起也可基于弯曲角度来确定。例如，如果在预定区域上感测到大于预定弯曲角度的弯曲，则该弯曲被定义为卷起。除了弯曲角度之外，还可以基于曲率半径来确定正常弯曲、折叠和卷起。
如上文中所述的，测量单元103由一个或多个传感器元件构成，通过一个或多个传感器元件以各种方式来感测柔性显示屏110的弯曲。
例如，测量单元103可以包括布置在柔性显示屏110的一个表面(比如，前表面或者后表面)上的弯曲感测器21、或者布置在柔性显示屏110的相对两个表面上的弯曲感测器21。
该弯曲感测器21是指可以被弯曲并且具有根据弯曲程度而变化的电阻值的感测器。该弯曲感测器21可以通过使用诸如光纤弯曲感测器、压力感测器和应变片之类的器件来实现。
弯曲感测器21的形状、数量和位置可以以各种方式改变。例如，柔性显示屏110可以包括单个弯曲感测器或者彼此连接的多个弯曲感测器。
图2图示在垂直方向和水平方向上布置成网格图案的多个条形弯曲感测器21的例子。
参考图2，测量单元103包括布置在第一方向上的弯曲感测器21-1到21-5，以及布置在垂直于第一方向的第二方向上的弯曲感测器21-6到21-10。弯曲感测器21被布置为彼此分开预定距离。
在图2中，在水平方向和垂直方向中的每一个方向上布置五个弯曲感测器(21-1到21-5，或者21-6到21-10)以形成网格式结构布置。然而，这仅仅是一个例子并且弯曲感测器21的数量可以根据柔性显示屏110的大小而改变。该弯曲感测器21被布置在水平方向和垂直方向上，是为了感测柔性显示屏110的整个区域的弯曲。因此，如果只有柔性显示屏110的一部分是柔性的或者如果柔性显示屏110只需要感测其一部分的弯曲，则弯曲感测器21可以仅仅被布置在柔性显示屏110的相应部分中。
如图2中所示，如果柔性显示屏110被弯曲以致其中心区域(相对左边缘和 右边缘而言)取向向下，那么弯曲导致的张力被施加在沿水平方向排列的弯曲感测器21-1到21-5。因此，沿水平方向排列的弯曲感测器21-1到21-5中的每一个的电阻值被改变。测量单元103感测到从弯曲感测器21-1到21-5中的每一个输出的输出值的变化，并因此确定对于显示屏表面的中心在水平方向上进行了弯曲。在图2中，中心区域向与显示屏表面垂直的向下方向(此后称为Z-方向)弯曲。但是，即使中心区域向以显示屏表面为基准的向上方向(此后称为Z+方向)弯曲，也可以基于沿水平方向排列的弯曲感测器21-1到21-5的输出值的变化而感测到弯曲。
同样，如果柔性显示屏110被弯曲以致其中心区域(相对上边缘和下边缘而言)取向向上，那么张力被施加在沿垂直方向排列的弯曲感测器21-6到21-10上。测量单元103可以基于沿垂直方向排列的弯曲感测器21-6到21-10的输出值来感测垂直方向上的形状变形。
如果形状变形出现在对角线方向上，则张力被施加在水平方向和垂直方向上排列的所有弯曲感测器21上。因此，基于沿水平方向和垂直方向排列的弯曲感测器21的输出值，可以感测对角线方向的形状变形。
图3是当柔性显示屏110被弯曲时的剖视图。
弯曲感测器31-1设置在柔性显示屏110的上表面(或前表面)上，所述上表面(或前表面)为柔性显示屏110面对用户的表面。
本发明中使用的术语“向外凸出”指在以显示屏表面为基准的方向上向上(或向前)凸出，具体来说，如图3中所示，点a5所在的部分为柔性显示屏的上端，点a1所在的部分为柔性显示屏的下端。当柔性显示屏的中心区域(点a3所在的区域)向外凸出时，相对于柔性显示屏的上端和下端来说，所述中心区域更靠近用户的眼睛。同时，当柔性显示屏的中心区域向外凸出时，柔性显示屏的上端和下端相互靠近。
相应的，当柔性显示屏的中心区域向内凹入时，相对于柔性显示屏的上端和下端来说，所述中心区域远离用户的眼睛。
在本发明中描述的柔性显示屏110的屏幕上端和下端，仅表示电子设备100 距离地面不同高度的两端，其中距离地面较远的为上端，距离地面较近的为下端。例如，柔性显示屏110的屏幕上端可以是智能手机安装摄像头的一端(通常意义上的上端)，也可以是智能手机麦克风所在的一端(通常意义上的下端)。柔性显示屏110的屏幕上端还可以是智能手机四边中的任意一端。
当柔性显示屏110被弯曲，则排列在柔性显示屏110的一个表面上或者相对表面上的弯曲感测器31也被弯曲，并具有与所施加的张力的大小对应的电阻值，并输出与该电阻值对应的值。
例如，如果柔性显示屏110的中心被如图3中所示那样向外凸出的弯曲，则布置在柔性显示屏110的上表面上的弯曲感测器31-1也被弯曲，并根据所施加张力的大小输出电阻值。
在这种情况下，张力的大小与弯曲程度成比例地增大。如果弯曲如图3中所示那样出现，则最大弯曲出现在中心区域。因此，最大张力被施加到布置在作为中心区域的点a3处的弯曲感测器31-1，因此，弯曲感测器31-1具有最大电阻值。在另一方面，弯曲程度朝着外侧逐渐减小。因此，随着从点a3到点a2和a1或者到点a4和a5的距离的增大，弯曲感测器31-1具有越来越小的电阻值。
如果从弯曲感测器31输出的电阻值在特定点具有最大值并且沿相反方向逐渐减小，则测量单元103可以确定从其感测到最大电阻值的区域被弯曲得最严重。
图4是根据本发明总体构思的示例性实施例的定义弯曲区域的方法的示意图。图4是图示柔性显示屏110在以前表面为基准的水平方向上弯曲的情况的视图，因此，为了说明方便，未示出沿垂直方向排列的弯曲感测器31。尽管不同的参考数字被用于每一附图中的弯曲感测器31，但是可以使用在图2中示出的弯曲感测器21，如同它们在图2中示出的那样。
弯曲区域是其中柔性显示屏110被弯曲的区域。由于通过弯曲柔性显示屏110，弯曲感测器31也被弯曲，所以输出与原始值不同的电阻值的弯曲感测器31所在的所有点都可以被定义为弯曲区域。
测量单元103可以基于在其处感测到电阻值的变化的点之间的关系，来感 测弯曲线BL的大小、弯曲线BL的方向、弯曲线BL的位置、弯曲线BL的数量、进行弯曲的次数、形状变形的弯曲速度、弯曲区域的大小、弯曲区域的位置以及弯曲区域的数量。
具体来说，如果在其处感测到电阻值的变化的点之间的距离落入预定距离以内，则这些点被感测为一个弯曲区域。在另一方面，如果在其处感测到电阻值的变化的点之间的距离超出预定距离，则关于这些点定义不同的弯曲区域。
图4是图示感测一个弯曲区域的方法的视图。如果柔性显示屏100如图4中所示那样被弯曲，则弯曲感测器31-1的点a1到a5、弯曲感测器31-2的点b1到b5、弯曲感测器31-3的点c1到c5、弯曲感测器31-4的点d1到d5、以及弯曲感测器31-5的点e1到e5的电阻值与原始状态中的这些点的电阻值不同。
在这种情况下，在每一弯曲感测器31-1到31-5中在其处感测到电阻值的变化的点位于预定距离内，并被连续排列。
因此，测量单元103把区域32感测为一个弯曲区域，该区域32包括弯曲感测器31-1的点a1到a5、弯曲感测器31-2的点b1到b5、弯曲感测器31-3的点c1到c5、弯曲感测器31-4的点d1到d5、以及弯曲感测器31-5的点e1到e5中的所有点。
弯曲区域可以包括弯曲线BL。弯曲线BL是指连接在其处从弯曲感测器31输出最大电阻值的不同的点的线。也就是说，在每个弯曲区域中连接在其处感测到最大电阻值的点的线被定义为弯曲线BL。
例如，在图4的情况中，在弯曲区域32中定义弯曲线BL，其连接点a3、b3、c3、d3和e3，它们是分别从弯曲感测器31-1、31-2、31-3、31-4和31-5输出最大电阻值的点。图4图示在垂直方向(可以是Z-或者Z+)上形成在柔性显示屏中心区域中的弯曲线BL。
可以以各种方式感测柔性显示屏110的弯曲方向。例如，两个弯曲感测器可以被布置为一个在另一个上面，并且基于每个弯曲感测器的电阻值的变化的差来确定弯曲方向。
两个弯曲感测器可以彼此重叠地布置在柔性显示屏110的一侧。在这种情 况下，如果在一个方向上进行了弯曲，则在进行了弯曲的点处从上方感测器和下方感测器61-2输出不同的电阻值。因此，通过比较两个弯曲感测器在同一点处的电阻值来确定弯曲方向。
具体地说，如果柔性显示屏110在Z-方向上弯曲，则施加于上方感测器的张力大于施加于下方感测器的张力。
另一方面，如果柔性显示屏100在Z+方向上弯曲，则在与弯曲线BL对应的点处施加于下方感测器的张力大于施加于上方感测器的张力。
两个弯曲感测器可以被彼此重叠地布置在柔性显示屏的一侧上，但是弯曲感测器也可以布置在柔性显示屏的相对两个表面上。
在这样的情况中，当柔性显示屏发生弯曲时，其中一个表面上的弯曲感测器受到压缩力，而另一个表面上的弯曲感测器受到张力。根据弯曲方向从两个表面上的弯曲感测器检测到不同的值，因此可以确定弯曲方向。
虽然在图2-4所示的示例性实施例中使用了线型弯曲感测器，但是也可以使用多个单独的应变片来感测弯曲。
每个应变片由金属或半导体材料制成，当应变片在外力作用下产生机械变形时，其电阻值相应发生变化。诸如由金属材料制成的应变片在其长度被外力拉伸的情况下电阻值增加，并且在长度收缩的情况下电阻值减小。因此，可以通过测量电阻值的变化来确定嵌入有应变片的柔性显示屏表面是否发生了弯曲。
除了上述各种类型传感器之外，测量单元103也可采用接触传感器感测柔性显示屏的相对两个边缘是否由于弯曲而彼此接触，测量单元103还可采用接近传感器感测所述边缘是否由于弯曲而彼此接近，彼此接近的区域彼此并不接触。
此外，除了以上所述的示例性实施例之外，柔性显示屏还可以使用各种感测器感测弯曲方向，所述各种感测器例如陀螺仪感测器、地磁感测器和加速度感测器。
如上所述，柔性显示屏可以使用各个种类的感测器感测弯曲。上述排列感 测器的方法和感测的方法可以被分别应用于柔性显示屏110，或者，可以被组合地应用于柔性显示屏110。
图5是根据本发明总体构思的示例性实施例的切换智能手机模式和可穿戴模式的示意图。
处理器可以基于由测量单元103感测的柔性显示屏110的弯曲信息来改变被显示在柔性显示屏110上的信息或者生成用于控制电子设备100的控制信号。
如图5中所示，当电子设备100的柔性显示屏110按照中心区域向外凸出的方式弯曲时，测量单元103同时感测所述柔性显示屏的上下两端之间的距离，当所述上下两端之间的距离小于预设值时，切换单元104将电子设备100由智能手机模式切换为可穿戴模式，电子设备100在可穿戴模式中作为智能手表或智能手环等可穿戴设备使用，此时，柔性显示屏110上显示与可穿戴设备相关的应用图标，与可穿戴设备相关的应用图标包括但不限于：计步器、心率计、时钟、健康、海拔高度表或睡眠统计等。如图5中所示，电子设备100被弯曲形成智能手环，此时显示的应用图标为计步器。
柔性显示屏的上下两端的距离的预设值的取值范围为1-8cm，优选的，预设值为1km、2km或3km等数值之一。
电子设备100处于可穿戴模式时，在柔性显示屏110也可以显示智能手机模式下的应用图标，即在柔性显示屏上除了显示上述计步器或心率计等图标之外，也可以同时显示电话、信息、提醒事项等图标。
可选的，如前面所述的，电子设备处于智能手机模式时采用第一情景模式，电子设备处于可穿戴模式时采用第二情景模式，在第二情景模式中，电子设备的所有通知方式均为静音或振动，用户可以通过弯曲电子设备来快速实现静音或振动效果。
可选的，电子设备切换为可穿戴模式时，在所述柔性显示屏上显示特定应用的功能界面，所述特定应用包括时钟、计步器、心率计、健康、提醒事项、信息、电话和海拔高度表中的至少一个或任意组合。例如，柔性显示屏上可以显示时间、当前步数、心率数值、短信或微信内容、未读电话号码等 信息。在可穿戴模式中，可以直接显示可穿戴设备常用的应用，减少用户的点击操作。例如，当用户常用的应用为计步器时，用户可以通过弯曲将电子设备由智能手机模式切换为可穿戴模式，并且在显示屏上直接显示当前步数，而跳过显示计步器图标的过程。
可选的，电子设备切换为可穿戴模式时，所述电子设备对当前运行的应用进行特定操作，所述特定操作包括调整音量或关闭应用。例如，当用户在智能手机模式中通过播放器应用观看电影时，可以通过弯曲将电子设备由智能手机模式切换为可穿戴模式，在可穿戴模式中，所述播放器应用被关闭或被变更为静音模式。
可选的，电子设备切换为可穿戴模式时，所述电子设备关闭在智能手机模式中已启动的一个或多个应用程序，所述应用程序可以是前台或后台运行的程序，通过关闭不相关的应用程序使得可穿戴模式下的电子设备可以具有更长的续航时间。
可选的，电子设备切换为可穿戴模式时，所述电子设备启动用户在可穿戴模式下常用的一个或多个应用程序。
在本发明中描述的柔性显示屏110的屏幕背面为远离使用者的一面，相应的，屏幕正面为正对使用者的一面，当柔性显示屏110可以双面显示时，在正对使用者的一面上显示图5中所示的计步器图标。
图6(a)至6(d)图示当柔性显示屏110切换为可穿戴模式时，在柔性显示屏110上的显示的信息如何变化。
如在图6(a)中所示，在未发生弯曲的柔性显示屏110上显示n(n为大于1的整数)个应用的图标，包括回收站、设置、腾讯、天气、股票、相机、图库、电子邮件和计算器。在该实施例中，n为9。上述9个应用包括第一优先级应用(腾讯、相机和电子邮件)、第二优先级应用(设置和计算器)、第三优先级应用(天气和股票)、第四优先级应用(图库)和第五优先级应用(回收站)。
柔性显示屏110的顶部具有状态栏显示区域111，状态栏显示区域111用于显示信号强度、未读短消息和时间。
如在图6(b)中所示，柔性显示屏110具有上端112和下端113，如前所述，上端112距离地面较远。当测量单元103(参见图1)检测到柔性显示屏110以中心区域向外凸出的方式弯曲，且上端112和下端113之间的距离小于预设值时，所述电子设备切换为可穿戴模式，在柔性显示屏的设定区域120上显示计步器应用的图标122，设定区域120为柔性显示屏110的一部分，设定区域120具有上边缘117、下边缘118、左边缘115和右边缘116，上边缘117和下边缘118间隔预定距离，弯曲线121位于上边缘117和下边缘118之间且与所述上下边缘的距离相等，所述左右边缘分别为柔性显示屏的左右边界。
预设区域120的上边缘117和下边缘118间隔预定距离，所述预定距离可以根据需要提前设定，也可以在使用过程中被用户修改。
如图6(b)中所示的，所述左右边缘分别为智能手机的左右边界，此时智能手机为竖屏显示，即智能手机的两条长边为左右边界，可选的，智能手机也可为横屏显示状态，此时智能手机的两条短边作为设定区域120的左右边界。
可选的，关闭预设区域120之外的其它区域或降低其亮度以降低功耗，提高续航能力。
在预设区域120确定之后，处理器确定在预设区域120显示的内容，所述显示内容可以是图像或应用图标122等。如在图6(b)中所示，在预设区域120上显示计步器应用的图标122。
应用图标122在预设区域120中的位置可以根据需要进行调整，可选的，应用图标122位于预设区域120的中央(即位于弯曲线121上)，或者，应用图标123也可以位于预设区域120的上部(即位于弯曲线121和上边117之间)，应用图标124还可以位于预设区域120的下部(即位于弯曲线121和下边118之间)。
如在图6(b)中所示，在预设区域120上显示一个应用图标122，可选的，在预设区域120上显示的应用图标数量为m个，m为不大于n的整数。例如，除了显示计步器应用的图标122，还可以显示时钟应用的图标、心率计应用 的图标等。
可以根据预设区域120的面积和需要显示的应用图标数量，放大或缩小预设区域120中显示的应用的图标。如在图6(c)中所示，在预设区域120面积较大的情况下，应用图标122被放大，使得图标大小可与预设区域的面积适配，进而使得图标更加清晰可见。
可选的，在预设区域120中显示的应用图标的尺寸小于在智能手机模式时应用图标的尺寸。例如，图6(a)中所示的回收站等应用的图标尺寸可为1cm*1cm，应用图标122的尺寸可被缩小为0.8cm*0.8cm。
可选的，在预设区域120中显示的应用图标具有不同的尺寸，例如，在预设区域120中可以显示计步器的应用图标和心率计的应用图标，其中，计步器是用户常用的应用，计步器的图标尺寸为0.8cm*0.8cm，心率计的图标尺寸为0.6cm*0.6cm。用户常用的应用由于具有更大的图标尺寸，因此方便用户进行准确点击。
在另一种情况中，在预设区域120中可以显示计步器的应用图标和心率计的应用图标，其中，计步器的图标尺寸为1.2cm*1.2cm，心率计的图标尺寸为0.6cm*0.6cm。通过增大不同应用的图标尺寸之间的差别，可以明显区分应用是否为常用的应用，此时，计步器的图标尺寸大于在智能手机模式时应用图标的尺寸。
如在图6(d)中所示，在预设区域120上显示的内容还可以是应用的某个功能界面。例如，在预设区域120的上部，显示计步器应用的功能界面，在该功能界面中显示用户当前已行走的步数12345。同时，在预设区域120的下部，还可以显示时钟应用的功能界面，在该功能界面中显示当前的时间08:00。
在另一种情况中，电子设备100在锁屏状态下具有未读信息，可以通过使电子设备100变为可穿戴模式，而在预设区域120上直接显示该未读信息的内容，未读信息包括但不限于未接电话、未读短息、未读微信等。例如，用户可以通过弯曲电子设备100使其在预设区域120上显示未接电话的电话 号码。
在预设区域120上显示的m个应用的图标可以具有相同或不同的优先级，所述m个应用的优先级大于未显示的应用的优先级，即优先显示用户常用的应用。
可选的，m个应用的图标中应用的优先级越高，则其图标越大，因此从应用图标大小可直观的反应出应用的优先级顺序，因此更有利于用户优先点击最高优先级的应用，防止图标较小导致的误操作。
上述在柔性显示屏110上显示的应用的具体内容和数量，在此仅为举例说明，上述应用可以为搭载
Figure PCTCN2016086630-appb-000003
或者其它操作系统的电子设备上使用的各种应用，包括但并不限于电话、短信、浏览器、相机、时钟、日历、天气、设置、音乐、文件管理、股票、微信、微博、腾讯、地图、电子邮件、图库、回收站、应用商店、计算器、新闻、游戏、计步器和心率计等。
上述应用可按照不同的优先级被划分为第一优先级应用、第二优先级应用至第X优先级应用，所述优先级由用户提前确定或由所述处理器根据用户使用所述应用的频率高低确定。例如，在某些情况下，用户可提前设定基础功能应用(短信，电话，时钟，设置等选项)为第一优先级(最高优先级)，社交类应用(如：电子邮件、微信、微博、腾讯等)为第二优先级，新闻类应用(如网易新闻、搜狐新闻等)为第三优先级，游戏类或视频类应用设定为第四优先级，购物类应用(淘宝、京东商城等)或网银类应用设定为第五优先级。
优先级也可由处理器180根据用户使用应用的频率高低确定，例如，用户最常用的应用为音乐、相机和计步器，则可将音乐、相机和计步器设定为第一优先级(最高优先级)，当测量单元103检测到柔性显示屏110发生弯曲时，在柔性显示屏的预设区域上显示该第一优先级应用的图标。同样的，第一优先级应用的具体内容和数量，在此仅为举例说明，并不是对第一优先级应用的具体内容和/或数量的限制。
在一个优选实施例中，当柔性显示屏110被外力弯曲为可佩带在用户手腕上的智能手环时，在预设区域上显示的第一优先级应用为计步器、心率计、音 乐和电话。
弯曲前后的柔性显示屏110可以采用不同的情景模式，以快捷的适应其应用形态的改变。例如，当柔性显示屏110为智能手机工作模式时，采用第一情景模式，在第一情景模式中，来电提醒使用第一音量大小的铃声1，新短信使用第二音量大小的铃声2，提示音使用第三音量大小的铃声3。当柔性显示屏110为可穿戴模式时，即当其在预设区域显示m个应用的图标时，来电提醒使用第一振动强度的振动1，新短信使用第二振动强度的振动2，提示音使用第三振动强度的振动3。由此，当用户参加会议时，可通过弯曲柔性显示屏使其工作在可穿戴模式，并且快速切换柔性显示屏的情景模式以避免干扰会议。
图6中示出了柔性显示屏110在外力作用下整体发生弯曲的情形，在某些情况下，柔性显示屏110也可被折叠，在下文中，将会参考附图详细地描述柔性显示屏110被折叠时，在柔性显示屏110上的显示的信息如何变化。
图7是图示当测量单元103感测到柔性显示屏110被折叠时，在柔性显示屏110上的显示的信息如何变化。
如图7(a)中所示，没有外力作用时，在未发生折叠的柔性显示屏110上同样显示n个应用的图标，其显示内容与图6(a)中相同，在此不再详述。
当测量单元103(参见图1)检测到柔性显示屏110被折叠时，根据弯曲线121的位置将柔性显示屏划分为不同的显示区域，即弯曲线之上的区域和弯曲线之下的区域。
如图7(b)中所示，在弯曲线121之上的区域中显示m个应用的图标。
在一个优选实施例中，当柔性显示屏110被外力折叠为与笔记本电脑具有类似形状时，在弯曲线121之上的区域中显示第一优先级应用，第一优先级应用为股票和文档。
图7(b)中所示的第一优先级应用(股票和文档)的具体内容和数量，在此仅为举例说明，并不是对第一优先级应用的具体内容和/或数量的限制。
与之前描述的相同，应用的图标可以被放大或缩小，并且应用图标的大小反映出优先级的高低。
与之前描述的相同，折叠前后的柔性显示屏可以采用不同的情景模式，以快捷的适应其应用形态的改变。
当柔性显示屏被折叠时，处理器可以检测用户输入单元是否存在输入信息，当存在输入信息时，如图7(c)中所示的，在弯曲线121之上的区域中显示内容，在弯曲线121之下的区域中显示用于控制内容的触摸交互信息。
其中，内容是指在每个应用中执行的主显示数据。例如，在网页浏览器应用的情况下，内容可以是网页数据。在电影的情况下，内容可以是图像数据。在文字处理的情况下，内容可以是文档数据。在游戏的情况下，内容可以是游戏执行屏幕。在相机拍摄的情况下，内容可以是拍摄图像。触摸交互信息可以是产生触摸事件的各种方式，例如用于选择、改变和移动前述内容的按钮和键盘。
作为其中一个示意性实施例，如图7(c)所示，当存在输入信息时，在弯曲线121之上的区域中显示文档数据，在弯曲线121之下的区域中显示对该文档数据进行编辑的虚拟键盘。
当处理器检测到用户输入单元不存在输入信息时，可在弯曲线121之上的区域中显示主菜单，在弯曲线121之下的区域中显示某一应用程序或文件的界面。
可选的，不存在输入信息时，在弯曲线121之上的区域中显示某一应用程序或文件的界面，在弯曲线121之下的区域中显示该应用程序或文件的上级或下级界面。
前述的主菜单，也可称之为主屏幕(home screen)，其为集合了若干应用程序和文件的展示列表，其同时也作为上述应用程序和文件的访问入口，在某些操作系统中，主菜单也可作为一个独立的应用程序存在。
在弯曲线121之上的区域中显示的所述内容或所述主菜单显然也可以在弯曲线121之下的区域中进行显示，同样的，在弯曲线121之下的区域中显示的所述触摸交互信息或所述应用程序或文件的界面也可以在弯曲线121之上的区域中进行显示，即二者显示的内容可交换其显示区域位置。
结合本发明公开内容所描述的方法的步骤可以硬件的方式来实现，也可以是由处理器执行软件指令的方式来实现。软件指令可以由相应的软件模块组成，软件模块可以被存放于RAM存储器、闪存、ROM存储器、EPROM存储器、EEPROM存储器、寄存器、硬盘、移动硬盘、CD-ROM或者本领域熟知的任何其它形式的存储介质中。一种示例性的存储介质耦合至处理器，从而使处理器能够从该存储介质读取信息，且可向该存储介质写入信息。当然，存储介质也可以是处理器的组成部分。处理器和存储介质可以位于ASIC中。另外，该ASIC可以位于用户设备中。当然，处理器和存储介质也可以作为分立组件存在于用户设备中。
