背景技术
目前，全面屏已经成为主流的手机等电子设备采取的设计方案，原来放在屏幕底部的指纹模组，需要调整位置。在一种方案中，指纹模组放置在屏幕内或屏幕的后方，目前也称之为屏幕下(under display，UD)指纹。
当指纹模组处于屏幕内或屏幕后方时，考虑到屏幕本身的整体性，指纹模组对应的屏幕上的指纹识别区域不会有让用户明确感知指纹位置的凸起或者凹下的挖孔。对此，现有技术中通常在屏幕上与指纹模组对应的区域显示一个指纹图标，用于指示指纹识别区域的位置，并在用户息屏后通过息屏显示(always on display，AOD)技术显示该指纹图标。
在采用AOD显示指纹图标的方案中，在息屏状态下，电子设备的应用处理器(application processor，AP)处于唤醒状态，电子设备进入息屏显示状态，如图1所示，电子设备持续在屏幕上显示指纹图标，便于用户随时在息屏状态下根据指纹图标进行指纹的解锁。而息屏显示状态下持续显示指纹图标将导致电子设备的功耗较大。

具体实施方式
为了便于理解，示例的给出了部分与本申请实施例相关概念的说明以供参考。如下所示：
息屏状态：也称灭屏状态，指在电子设备检测到息屏事件之后且检测到亮屏事件之前的时间段内，手机屏幕所处的状态。
息屏显示：在检测到息屏事件后，屏幕的一部分区域熄灭，另一部分区域点亮以用于显示时间或通知等信息。其中，对于液晶显示(liquid crystal display，LCD)屏幕来说，可以通过关闭屏幕的背光来实现息屏；对于有机发光二极管(organic light emitting diode，OLED)显示屏来说，可以通过控制屏幕中发光点不发光来实现息屏。
设备节点：一个设备节点其实就是一个文件，因而设备节点也可以称为设备文件，用于设备间访问。例如，在linux中，所有的设备访问都是通过文件的方式进行，设备节点通过“mknod”命令来创建。
驱动(driver)：添加到操作系统中的小块代码程序，是根据操作系统编写的配置文件，其中包含有关硬件设备的信息，用于计算机软件(computer software)和硬件(hardware)之间进行通信。
处理器间通信(inter processor communication，IPC)：为了满足通信、多媒体和数字处理等高端应用，片上系统己不仅仅集成一个处理器，而更多的是将多个处理器集成到系统中，甚至还需要结合片外的处理器共同工作。由于系统集成了多个处理器，每个处理器可以相当于系统的一个主机，各个处理器在与共享资源间通信。例如，处理器间通信方式可以包括：共享存储器通信机制、mailbox硬件通信机制、直接内存存取(direct memory access，DMA)数据搬运通信机制和串口主从模式通信机制等。

以下将通过具体实施例对本申请实施例提供的提示信息显示方法进行详细描述。
本申请实施例提供了一种提示信息的显示方法，可以应用于具有触摸显示屏幕的电子设备，参见图3，该方法包括：
301、在电子设备处于息屏状态时，电子设备在屏幕上显示提示信息，该提示信息包括指纹标识，该指纹标识用于指示指纹识别区域。
具体的，电子设备可以通过AP检测息屏事件，在检测到息屏事件后，电子设备息灭部分或整个屏幕，进入息屏状态。示例性的，电子设备检测到息屏事件可以包括：电子设备在亮屏或暗屏状态下，检测到电源键被按下；或者，电子设备在亮屏或暗屏状态下的预设时间段内(例如一分钟)未检测到用户的操作；或者，电子设备在亮屏 或暗屏状态下，检测到预设的息屏手势(例如在桌面上双击)；或者，电子设备在亮屏或暗屏状态下，检测到光线被遮挡(例如手机放入口袋或包里等)。其中，在亮屏状态下，若电子设备在预设时间段内未检测到用户的输入操作，则降低屏幕整体亮度，此时电子设备进入暗屏状态。在暗屏状态下，若电子设备仍然未检测到用户的输入操作，则暗屏状态持续较短的时间(例如几秒钟)后进入息屏状态；若电子设备检测到用户的输入操作，则电子设备重新进入亮屏状态。需要注意的是，用于指示电子设备息屏的息屏事件还可以包括其它，这里不再一一说明。
其中，用于标识指纹识别区域的指纹标识可以有多种形式，本申请实施例不予具体限定。例如，该指纹标识可以是如图1所示的一个指纹图案，或者如图4中(a)所示的锁形图案，或者如图4中(b)所示的一个圆圈、圆点或圆球图案，或者如图4中(c)所示的一个笑脸图案，或者如图4中(d)所示的指示字符，该图案或字符所在位置用于指示该指纹识别区域，该图案或字符覆盖的区域与指纹识别区域之间有交集，指纹识别区域为指纹识别器件在屏幕上所对应的区域。该指纹标识也可以是如图4中(e)所示的一个指示箭头或如图4中的(f)所示的指引手势的图形，该指示箭头或指引手势所指的位置用于指示该指纹识别区域。或者，该指纹标识也可以是动画播放区域，动画播放区域所在位置用于指示该指纹识别区域等。
具体的，指纹标识所在的区域可以完全包括屏幕内或屏幕后指纹识别器件所覆盖的区域。其中，这里的“屏幕内”和“屏幕后”均表示指纹区域设置在屏幕的里面而非屏幕的表面，属于相同含义的表述，以下将统一采用“屏幕内”进行描述。或者，指纹标识所在的区域可以被完全包括在屏幕内指纹识别器件所覆盖的区域内。或者，指纹标识所在的区域与屏幕内指纹识别器件所覆盖的区域之间有部分交集。或者，指纹标识所在的区域与屏幕内指纹识别器件所覆盖的区域之间的距离小于或者等于预设距离值，即指纹标识所在的区域在屏幕内指纹识别器件所覆盖的区域的附近，或指纹标识所在的区域与屏幕内指纹识别器件所覆盖的区域相邻。
电子设备进入息屏状态后，可以在屏幕上显示提示信息。具体的，电子设备可以默认在进入息屏状态后首先在屏幕上显示提示信息，或者电子设备可以先不显示提示信息而在满足第二预设条件时才在屏幕上显示提示信息。
302、在电子设备在屏幕上显示提示信息之后，若满足第一预设条件，则电子设备停止在屏幕上显示提示信息。
在息屏状态下，在电子设备在屏幕上显示提示信息之后，当满足第一预设条件时，电子设备可以停止在屏幕上显示提示信息。
也就是说，在息屏状态下，参见图5，电子设备可以在一段时间内显示提示信息，此时电子设备处于息屏显示状态；而在另一段时间内电子设备可以不显示提示信息，此时电子设备可以退出息屏显示状态。即，电子设备可以根据实际需要进入或退出息屏显示状态，从而在屏幕上间歇性地、动态地显示指纹标识等提示信息，而不像现有技术那样需要在息屏状态下保持息屏显示状态以持续显示指纹图标，因而可以降低电子设备的功耗。
进一步地，在上述步骤302之后，该方法还可以包括：
303、若满足第二预设条件，则电子设备在屏幕上显示提示信息。
在电子设备停止在屏幕上显示提示信息之后，若满足第二预设条件，则电子设备可以再次在屏幕上显示提示信息。
如图6所示，本申请实施例提供了另一种提示信息的显示方法流程图。该方法包括：601、在亮屏状态下，电子设备正常工作；602、当电子设备检测到息屏事件时，电子设备进入息屏状态；603、在进入息屏状态后，电子设备判断是否默认显示提示信息，若是，则执行步骤604，若否，则执行步骤605；604、若默认显示提示信息，则电子设备在屏幕上显示提示信息，然后执行步骤606；605、若未设置默认显示提示信息，则电子设备判断是否满足第二预设条件；若满足第二预设条件，则电子设备执行步骤604以在屏幕上显示提示信息；若不满足第二预设条件，则电子设备不显示提示信息，并且可以持续判断是否满足第二预设条件；606、在显示提示信息之后，电子设备判断是否检测到亮屏事件，若是，则执行步骤607，若否，则执行步骤608；607、若在步骤606中检测到亮屏事件，则电子设备退出息屏状态；608、若在步骤606中未检测到亮屏事件，则电子设备判断是否满足第一预设条件，若是，则执行步骤609，若否，则可以持续检测是否满足第一预设条件；609、若满足第一预设条件，则电子设备停止在屏幕上显示提示信息；610、在电子设备停止在屏幕上显示提示信息之后，电子设备判断是否检测到亮屏事件；若在步骤610中检测到亮屏事件，则电子设备执行步骤607以退出息屏状态；若在步骤610中未检测到亮屏事件，则电子设备执行步骤605以判断是否满足第二预设条件；如此循环执行以上各步骤，直到电子设备退出息屏状态。
在本申请实施例中，电子设备可以包括第一处理器和第二处理器，该第一处理器可以为应用处理器AP，该第二处理器为协处理器。可用于本申请实施例中第二处理器的协处理器可以有多种，本申请以下实施例将以第二处理器为协处理器sensorhub为例进行说明。在电子设备处于亮屏状态或暗屏状态时，若AP检测到息屏事件，则电子设备可以进入息屏状态；在息屏状态中，电子设备可以通过sensorhub指示屏幕显示提示信息或停止显示提示信息。
在息屏状态下，AP可以进入休眠状态，电子设备可以通过sensorhub管理和控制提示信息的显示和关闭。而与AP相比，sensorhub是低速、小功耗的协处理器，例如具体可以是ARM cortex M3、M4等。因而，与现有技术在息屏状态下AP处于唤醒状态以控制指纹图标持续显示相比，本申请实施例通过低功耗的协处理器sensorhub代替管理和控制指纹标识的显示，能够降低电子设备的功耗。
并且，在本申请实施例中，在息屏状态下，电子设备能够通过低功耗协处理器sensorhub间歇性地动态显示指纹标识，从而能够显著地节省电子设备的电量。
具体的，sensorhub可以用于管理至少一个传感器和/或屏幕。电子设备在屏幕上显示提示信息或停止显示提示信息，具体可以包括：sensorhub根据至少一个传感器的检测数据和/或屏幕的中断事件，指示屏幕显示提示信息或停止显示提示信息。示例性的，当电子设备为手机时，至少一个传感器可以包括图2所示的传感器。屏幕的中断事件可以包括悬浮事件或触碰事件等。
示例性的，在本申请实施例中，第二预设条件可以包括以下任意一种条件或任意多种条件的组合：电子设备被抬起；或者，电子设备检测到屏幕被触碰；或者，电子 设备在指纹识别区域或预设区域内检测到悬浮事件；或者，在手持运动状态下，电子设备检测到电子设备正面朝上；或者在手持运动状态下，电子设备检测到电子设备侧面朝上，且在指纹识别区域或预设区域内检测到大于或者等于预设值的压力值。
在一种具体实现中，参见图7，在未显示提示信息的状态下，若电子设备检测到被抬起，则显示提示信息。
例如，在静置或平放时，电子设备可以将指纹标识显示预设时长后停止显示。当电子设备被抬起时，电子设备可以再次显示指纹标识。
具体的，sensorhub可以通过传感器(例如加速度传感器和/或陀螺仪)的检测数据判断电子设备是否被抬起，从而在电子设备被抬起时指示屏幕显示指纹标识。
在另一种具体实现中，参见图8，在未显示提示信息的状态下，若电子设备检测到屏幕被触碰，则显示提示信息。
具体的，sensorhub可以通过屏幕(例如电容式、电感式或红外式触摸显示屏幕)判断是否有手指或电子笔的触碰事件。当产生触碰事件时，可以说明用户主动触发显示提示信息，屏幕产生触碰中断事件并通知sensorhub，sensorhub指示屏幕显示指纹标识。
在另一种具体实现中，在未显示提示信息的状态下，若电子设备在指纹识别区域或者在预设区域(例如指纹识别区域附近的区域、屏幕的下半部分、屏幕的中间区域或屏幕的左下角、右下角等)内检测到悬浮事件，则显示提示信息。
具体的，sensorhub可以通过距离传感器的检测数据或通过屏幕(例如电容触摸显示屏幕中电容的变化)判断指纹识别区域或预设区域上方是否有手指悬浮事件。当产生悬浮事件时，距离传感器或触摸显示屏幕产生悬浮中断事件并通知sensorhub，sensorhub指示屏幕显示指纹标识。
示例性的，参见图9，在未显示提示信息的状态下，若电子设备在手指距离屏幕上指纹识别区域距离为d时检测到手指的悬浮事件，则显示指纹标识。
在另一种具体实现中，在未显示提示信息的状态下，当电子设备被“摇一摇”时，显示提示信息。
具体的，sensorhub可以通过振动传感器或加速度传感器的检测数据确定电子设备被“摇一摇”时，指示屏幕显示提示信息。
在另一种具体实现中，在未显示提示信息的状态下，当电子设备检测到光线明显变亮时，显示提示信息。
例如，当电子设备从口袋或包里掏出来时，用户可能想要使用电子设备，电子设备检测到光线明显变亮，此时可以显示指纹标识，以便用户解锁。
具体的，sensorhub可以根据环境光传感器的检测数据，判断光线是否变亮，从而来判断电子设备是否从口袋或包里拿出，进而指示屏幕是否显示指纹标识。
在另一种具体实现中，在手持运动状态且未显示提示信息时，若电子设备检测到电子设备正面朝上，则显示提示信息。
其中，电子设备正面是指电子设备屏幕所在的那一面，用户通常是在电子设备屏幕所在的那一面朝上时才会使用电子设备，因而当电子设备屏幕所在的那一面朝上时，电子设备可以显示提示信息。
需要说明的是，电子设备的正面朝上是指，从整体趋势上来说电子设备的正面基本朝上，包括如图10中(b)所示的电子设备的正面不完全朝上的情况。
具体的，在手持运动模式下，用户在运动时通常是侧握手势，即电子设备的侧面基本朝上，用户通常在需要使用手机时才会将手机翻转过来，从而使得电子设备的正面基本朝上。sensorhub可以通过加速度传感器和压力传感器确定电子设备是否为手持运动模式；通过陀螺仪可以确定电子设备是否正面基本朝上；并在电子设备正面基本朝上时指示屏幕显示指纹标识。
示例性的，当电子设备由如图10中(a)所示的侧面基本朝上翻转为如图10中(b)所示的侧面基本朝上时，电子设备显示指纹标识。
在另一种具体实现中，在手持运动状态且未显示提示信息时，若检测到电子设备侧面朝上，且在指纹识别区域或预设区域内检测到大于或者等于预设值的压力值，则显示提示信息。
由于运动状态下，当电子设备侧面朝上时，用户侧握电子设备，而用户通常不会在侧握电子设备时使用电子设备。因而，若用户在运动状态采用侧握手势时，电子设备在指纹识别区域或预设区域内检测到触碰，则可能是用户无意识的误触，因而可以不显示指纹标识。而参见图11中的(a)在检测到触碰的压力值大于或者等于预设值(即压力按)时，可以说明是用户有意识的触发，此时参见图11中的(b)，电子设备可以显示指纹标识。这样，可以降低误触发的概率，降低显示功耗。
或者，若用户在运动状态采用侧握手势时，电子设备在指纹识别区域或预设区域内检测到触碰，且触碰时间大于或者等于预设时长(即长按)时，可以说明是用户有意识的触发，电子设备可以显示指纹标识。
或者，若用户在运动状态采用侧握手势时，电子设备在指纹识别区域或预设区域内检测到双击等其它区别于简单触碰的事件，可以说明是用户有意识的触发，电子设备显示指纹标识。
而在非运动状态下，例如用户站立或躺着时，若用户侧握电子设备，且在指纹识别区域或预设区域内检测到触碰，则通常是用户有意识的触碰，因而电子设备可以显示指纹标识。
在另一种具体实现中，当电子设备由正面朝上翻转至背面朝上(即将电子设备扣下)再翻转至正面朝上时，电子设备显示提示信息。
在另一种具体实现中，当电子设备接收到用户的第一语音指示(例如显示提示信息、提示等)时，显示提示信息。
示例性的，在本申请实施例中，第一预设条件可以包括以下任意一种条件或任意多种条件的组合：电子设备检测到显示提示信息的时长大于或者等于预设时长；或者，电子设备检测到光线被遮挡；或者，在手持运动状态下，电子设备检测到电子设备侧面朝上。
在一种具体实现中，在显示提示信息的状态下，若电子设备检测到本次显示时长大于或者等于预设时长，则停止显示提示信息。
具体的，在显示提示信息的状态下，例如电子设备在静置或平放(例如放在桌上、床上或车内)时显示提示信息的状态下，若sensorhub确定显示时间长度大于或者等于 预设时长(例如5s)，则可以说明用户应该并不想使用电子设备，否则用户应该已经在预设时长内进行指纹解锁，因此sensorhub可以指示屏幕停止显示指纹标识。
在另一种具体实现中，在显示提示信息的状态下，若电子设备检测到显示时长超过预设时长且未检测到用户输入操作，则停止显示提示信息。其中，用户输入操作可以包括触摸操作、悬浮操作、按键操作或语音操作等，触摸操作和悬浮操作具体可以是手指的操作也可以是电子笔的操作，这里不予具体限定。
在另一种具体实现中，在显示提示信息的状态下，若电子设备检测到光线被遮挡，则停止显示提示信息。
例如，当电子设备被放进口袋或包里，用户不想使用电子设备时，电子设备可以检测到光线被遮挡，从而不显示该指纹标识。若电子设备在被放进口袋或包里之前显示有指纹标识，则在放进口袋或包里之后可以停止显示该指纹标识。若电子设备在放进口袋或包里之前也未显示指纹标识，则在放进口袋或包里之后，仍然不显示指纹标识。
具体的，sensorhub可以根据接近传感器和环境光传感器等的检测数据，通过判断光线是否被遮挡以及电子设备距离其它物体的远近，从而来判断电子设备是否被放进了口袋或包里，进而指示屏幕是否停止显示指纹标识。
在另一种具体实现中，在手持运动状态且显示提示信息时，若电子设备检测到电子设备侧面朝上，则停止显示提示信息。
由上述分析可知，运动状态下，当电子设备侧面朝上时，用户侧握电子设备，而用户通常不会在侧握时使用电子设备。sensorhub可以通过加速度传感器和压力传感器确定电子设备是否为手持运动模式；通过陀螺仪可以确定电子设备是否侧面基本朝上；并在电子设备是侧面基本朝上时不显示指纹标识。
例如，当电子设备由正面基本朝上翻转为侧面基本朝上时，停止显示指纹标识。
在另一种具体实现中，无论是否处于手持运动状态，当电子设备正面基本朝上时，显示提示信息；当电子设备侧面基本朝上时，停止显示提示信息。
在另一种具体实现中，当电子设备接收到用户的第二语音指示(例如关闭或停止显示提示信息、不显示提示信息等)时，停止显示提示信息。
在另一种具体实现中，电子设备可以默认不显示提示信息，在满足预设条件时才显示提示信息。
其中，满足预设条件可以表明用户可能想要使用电子设备。满足预设条件的具体情形可以为上述显示指纹标识的具体实现方式中的一种或多种的结合(例如，检测到触碰事件或者检测到第一语音指示等)。这样，在息屏状态下，电子设备通常可以在大部分时间内不显示指纹标识，而在需要时才显示指纹标识，因而能够更多地降低电子设备的功耗。
需要说明的是，本申请实施例所描述的息屏状态下电子设备显示或停止显示指纹标识的具体实现方式仅是举例说明，还可以包括其它显示或停止显示指纹标识的具体实现方式，也可以是两种或多种实现方式的组合，例如在未显示指纹标识时电子设备可以在被抬起且检测悬浮事件时显示指纹标识等，此处不再赘述。
在亮屏状态下，AP管理和控制整个电子设备正常工作；在息屏状态下，AP交由sensorhub管理和控制提示信息的显示。AP与sensorhub之间设置有用于信息交互的接口协议(或称为通信机制)。
其中，该接口协议可以包括指示命令和传输通道，还可以包括指示命令的发送时机及功能等。该指示命令可以包括启动命令、停止命令、显示规则命令或初始化命令等中的一个或多个。该显示规则命令用于指示显示规则，例如可以包括配置显示区域命令或设置图片大小命令等中的至少一个。该配置显示区域命令可以用于将待显示区域的位置通知给sensorhub，该设置图片大小命令可以用于将可显示的图片的大小(例如像素尺寸)通知给sensorhub。并且，指示命令具体可以为机器可以识别的命令字的形式。指示命令可以具有一定的参数格式，例如命令可以包括名称、参数(type)和数值(value)。示例性的，配置显示区域命令的格式具体可以参见如下表1：
表1
Figure PCTCN2018080578-appb-000001
其中，该传输通道可以为AP-IPC-sensorhub。即，AP和sensorhub之间可以通过IPC通道进行命令等信息的交互，从而实现AP与sensorhub之间的通信。
以下将对指示命令的发送时机及功能进行具体说明。
AP在检测到息屏事件后向sensorhub发送启动命令。sensorhub在接收到AP发送的启动命令后启动息屏显示功能。其中，若该启动命令时AP首次发送的启动命令，则AP还可以向sensorhub发送初始化命令，以将AP侧和sensorhub侧用于息屏显示的模块进行初始化；并且，AP还可以向sensorhub发送显示规则命令，以将提示信息的显示规则通知给sensorhub。其中，AP在开机后或者用户打开电子设备上的息屏显示开关(例如图12所示设置界面中的息屏显示开关)后第一次发送的启动命令，可以称为AP首次发送的启动命令。在发送启动命令(以及初始化命令和显示规则命令)之后，AP可以进入休眠状态，以降低电子设备的功耗。
具体的，AP可以通过IPC通道向sensorhub发送启动命令、初始化命令和显示规则命令。sensorhub在接收到初始化命令后，可以初始化sensorhub管理和控制的用于息屏显示的各个模块，例如显示子系统DSS。sensorhub在接收到启动命令后可以启动息屏显示功能。sensorhub在首次接收到启动命令后可以通过IPC通道向AP发送反馈信息，从而建立AP与sensorhub之间的通信通道。sensorhub在接收到启动命令后，可以指示sensorhub侧的显示子系统DSS上电，指示DSS根据AP指示的显示规则获取提示信息的待显示内容，并将待显示内容刷新至屏幕中的显示面板(例如LCD显示面板或OLED显示面板等)，即DSS将待显示内容送显。在送显后，DSS可以下电，从而进入低功耗状态，以降低电子设备的功耗；在DSS下次需要刷新显示内容时，DSS才会再次上电。其中，共享内存中的待显示内容是机器语言，例如指纹标识可能是一个指纹图标，但指纹图标的待显示内容是一些用于描述该指纹图标的字符串。
需要注意的是，在此次息屏状态下，DSS不需要再次刷新显示内容，因而可以在 此次息屏状态下不会再次上电，因而可以节省电子设备的电量。
在sensorhub根据上述可能的实现方式确定需要显示提示信息时(例如检测到触碰事件时)，向显示面板发送显示指示，显示面板根据DSS送显的提示信息的待显示内容绘制图形用户界面(GUI)，从而在屏幕上显示提示信息，电子设备进入息屏显示状态。
需要注意的是，在本申请实施例中，电子设备中存在AP和sensorhub都可以直接访问的共享内存(该共享内存不同于AP侧自身的显示内存)，该共享内存可以是预设的也可以是动态申请的，DSS在初始化时指向该共享内存。AP侧将待显示内容写入共享内存，DSS从该共享内存中获取待显示内容，从而将待显示内容刷新至显示面板。例如，参见图13，当用户指示将指纹标识由指纹图标更换为圆圈时，AP可以将更新后的内容写入共享内存，在下一个息屏状态下，sensorhub启动息屏显示功能后，DSS可以从共享内存中获取更新后的圆圈并送显，显示面板在需要显示指纹标识时显示更新后的圆圈。也就是说，待显示内容需要更换时，AP才会更新共享内存中的内容；而在待显示内容不需要更换时，AP侧不会频繁更新。当提示信息为指纹标识时，待显示内容在此次息屏状态下不需要更新，AP可以进入休眠状态，从而节省电子设备的功耗。
在sensorhub根据上述可能的实现方式确定需要停止显示提示信息时(例如提示信息的显示时长超过预设时长时)，向显示面板发送停止显示指示，显示面板可以息灭，电子设备停止息屏显示。
可选的，在一种可能的实现方式中，共享内存中可以保存有多个指纹标识，该指纹标识可以位于同一区域，但不同指纹标识对应不完全相同的像素点。在息屏状态下sensorhub每次显示指纹标识时，显示面板可以轮流或随机显示共享内存中的一种指纹标识。这样，每次显示指纹标识时点亮的像素点可以不完全相同，从而可以降低烧屏的风险，同时也可以给用户较好的视觉体验。示例性的，共享内存中存储了三种指纹标识，参见图14，电子设备在每次需要显示指纹标识时，轮流显示共享内存中的每个指纹标识。
在电子设备检测到亮屏事件后，AP被唤醒并向sensorhub发送另一指示命令即停止命令，用于指示sensorhub关闭息屏显示功能。sensorhub在接收到AP发送的停止命令后关闭息屏显示功能以停止息屏显示，且电子设备亮屏，退出低功耗模式。sensorhub再次接收到AP发送的启动命令后，重新启动息屏显示功能。电子设备检测到亮屏事件的情况可以有很多，例如，电子设备在息屏状态下检测到电源键被触发，或者在息屏状态下检测到预设手势(例如双击屏幕)，或者有来电呼入，或者接收到短信等等，这里不再一一例举。
在一种具体实现方式中，在电子设备开机后，或者在用户打开电子设备上的息屏显示开关后，或者在用户重新录入指纹后等，AP在检测到息屏事件后发送的启动命令可以称为启动命令；在指纹解锁开启且屏内指纹有录入的情况下，AP在检测到息屏事件后发送的启动(start)命令还可以称为恢复(restore)命令。在电子设备已经根据启动命令成功进入熄屏显示状态，并收到亮屏指令的情况下，电子设备发送的停止(stop)命令也可以称为暂停(pause)命令。
在一种可能的设计中，如图15所示，电子设备的AP侧可以包括第一AOD应用、 AOD框架(framework)、第一AOD驱动以及共享内存等模块；电子设备的sensorhub侧可以包括第二AOD应用、第二AOD驱动、DSS驱动、sensor管理应用、sensor驱动、TP应用以及TP驱动等模块。并且，电子设备还可以包括显示面板、至少一个传感器、触控面板、指纹识别器件等硬件，显示面板和触控面板TP可以合为本申请实施例中的触摸显示屏幕。此外，电子设备还可以包括指纹验证模块，可以用于与指纹识别器件配合验证指纹是否合法。
基于图15所示结构的电子设备，上述传输通道AP-IPC-sensorhub具体可以为第一AOD应用-AOD框架-第一AOD驱动-IPC-第二AOD应用-第二AOD。本申请实施例中的指示命令可以通过该具体传输通道进行传输。其中，第一AOD应用与第一AOD驱动之间可以通过设备节点进行信息传输。
其中，第二AOD应用、第二AOD驱动、DSS驱动以及显示面板可以用于根据在需要时显示指纹标识，在不需要时停止显示指纹标识。sensor管理模块、sensor管理驱动以及至少一个传感器可以用于获取传感器检测数据，将传感器事件上报给第二AOD应用，以便于第二AOD应用确定是否需要显示或停止显示指纹标识。TP应用以及TP驱动以及触控面板等模块可以用于检测悬浮事件、触碰事件等中断事件并上报给第二AOD应用，以便于第二AOD应用确定是否需要显示或停止显示指纹标识。
此外，在另一种可能的设计中，电子设备屏幕的贴膜上可以设置有指纹标识，用于提示用户指纹识别区域的位置。例如，该指纹标识可以是一块设置有多个小突起的区域(用户触摸时给予用户类似磨砂的感觉)，一层具有视觉提示的丝印，一块具有视觉凸起或凹陷的区域，或者一块具有凸起或凹陷的区域等。
进一步地，本申请实施例中的提示信息还可以包括其它信息，例如时间信息、日期信息、电量信息、短信提示或未接来电提示等中的一个或多个。本申请上述实施例是以提示信息为指纹标识为例，对息屏状态下显示或停止显示提示信息的方式进行说明的，上述息屏状态下动态显示指纹标识的方式也可以应用于提示信息中的时间信息、日期信息等其它信息，这里不再赘述。
需要说明的是，参见图16，在息屏状态下，时间信息等提示信息可以像指纹标识一样在需要时再显示，否则不显示，以降低电子设备的功耗。在另一种可能的实现方式中，参见图17，在息屏状态下，指纹标识可以在需要时显示，时间信息等提示信息可以持续显示。在另一种可能的实现方式中，在息屏状态下，sensorhub可以持续显示时间信息等提示信息，电子设备可以持续处于息屏显示状态，本申请实施例不予具体限定。
当提示信息还包括其它信息时，指示命令还可以包括启动更新命令和结束更新命令等；当提示信息还包括时间信息和日期信息时，指示命令还可以包括设置时间时区格式命令。
其中，在AP首次发送启动命令时，除了可以发送显示规则命令，还可以发送设置时间时区格式命令，以将时间时区格式发送给sensorhub，便于sensorhub在息屏状态下根据时间时区格式显示时间和日期。
此外，还需要说明的是，当提示信息仅包括指纹标识时，在息屏状态下，AP进入休眠状态以节省功耗；当提示信息还包括其它信息时，在息屏状态下，AP可以在其它 信息需要更新时被唤醒，并向sensorhub发送启动更新命令和结束更新命令，从而指示sensorhub更新显示的其它信息。也就是说，当提示信息还包括其它信息时，在息屏到亮屏期间，在其它信息需要更新时，AP被唤醒，向sensorhub发送启动更新命令，并将更新后的其它信息的待显示内容的写入共享内存，在写入完成后，AP向sensorhub发送结束更新命令，sensorhub指示DSS上电。上电后的DSS获取更新后的其它信息的待显示内容，并将更新后的其它信息的待显示内容传送至显示面板，而后DSS可以下电以降低功耗。显示面板显示更新后的其它信息。具体的，屏幕可以在DSS送显后立即显示更新后的其它信息，也可以在电子设备需要显示提示信息时再显示更新后的其它信息，本申请实施例不予限定。
例如，sensorhub自身可能并不能准确维护日期信息，因而在息屏状态下需要更新日期时，AP被唤醒后可以向sensorhub发送启动更新命令，并把更新后的日期内容写入共享内存；AP在完成写入后可以向sensorhub发送结束更新命令；sensorhub在接收到结束更新命令后，可以指示DSS从共享内存中获取更新后的日期内容并送显，显示面板在需要显示日期内容时显示更新后的日期。再例如，在息屏状态下，当电子设备接收到短信时，AP被唤醒，向sensorhub发送启动更新命令和结束更新命令，从而指示sensorhub更新短信信息(例如，将未读短信数量由1更新为2，或者若之前未显示短信图标则显示短信图标等)。
另外，当提示信息还包括其它信息时，共享内存中保存的每一类信息都存储在固定的区域内(例如，指纹标识、短信图标和短信数量可以分别存储在不同的区域)。只有在某类信息发生变化时AP侧才会进行更新，而在每类信息都没有发生变化时，AP侧不会进行更新，因而可以避免AP的频繁更新，降低电子设备的功耗。尤其地，在本申请实施例中，在息屏状态下，sensorhub可以不需要AP的参与维护并显示时间；而在现有技术中，在息屏状态下，每分钟都需要唤醒AP刷新当前时间，因而息屏状态下AP也通常处于唤醒状态，从而增大了电子设备的功耗。
还需要说明的是，在息屏状态下，即使指纹标识可以在需要时显示，时间信息等提示信息可以持续显示，或者即使sensorhub持续显示时间信息等提示信息，由于该显示过程仅在个别情况下(例如需要更新日期时)需要唤醒AP，而大多数时候则不需要AP的参与，通过低速、低功耗的sensorhub就可以实现，因而仍然可以降低电子设备的功耗。
本申请另一实施例提供了一种显示图形用户界面(GUI)的方法，该方法在具有触摸显示屏幕的电子设备中实现，参见图18，该方法可以包括：
1801、在电子设备处于息屏状态时，电子设备在屏幕上显示第一GUI，第一GUI中显示了提示信息，该提示信息包括指纹标识，该指纹标识用于指示指纹识别区域。
1802、在电子设备在屏幕上显示第一GUI之后，响应于满足第一预设条件，电子设备停止在屏幕上显示第一GUI。
示例性的，该第一GUI可以为如图1、图4、图14、图16或图17中显示有提示信息的界面。
这样，电子设备可以根据实际需要在屏幕上间歇性地、动态地显示包括有指纹标识等提示信息的GUI，而不像现有技术那样需要在息屏状态下持续显示指纹图标，因 而可以降低电子设备的功耗。
进一步地，在步骤1802之后，该方法还可以包括：
1803、响应于满足第二预设条件，电子设备在屏幕上显示第二GUI，第二GUI上显示了提示信息。
具体的，电子设备可以包括第一处理器和第二处理器，在电子设备处于亮屏状态或暗屏状态时，响应于第一处理器检测到息屏事件，电子设备可以进入息屏状态，第一处理器交由第二处理器来控制是否提示信息。在电子设备处于息屏状态时，第二处理器指示屏幕显示第一GUI；在显示提示信息后，当满足第一预设条件时，第二处理器可以指示屏幕停止显示第一GUI。其中，该第一处理器为应用处理器AP，第二处理器为协处理器，例如sensorhub。
由于协议处理器sensorhub是比AP更低速、功耗更小的协处理器，因而与现有技术在息屏状态下AP处于唤醒状态以控制指纹图标持续显示相比，本申请实施例通过低功耗的协处理器sensorhub代替管理和控制GUI上指纹标识等提示信息的显示，能够降低电子设备的功耗。
其中，关于第一预设条件和第二预设条件的具体内容以及AP交由sensorhub控制指示信息是否显示的具体过程可以参见上述实施例中的相关描述，这里不再赘述。
需要说明的是，上述步骤1801-1803均为电子设备处于息屏状态下的步骤。
