Description

一种灭屏显示方法及电子设备
本申请要求于2021年3月30日提交国家知识产权局、申请号为202110342483.3、申请名称为“一种灭屏显示方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种灭屏显示方法及电子设备。.
背景技术
现在大多数智能设备都支持常显示(Always on display，AOD)功能，也称为灭屏显示功能。所谓的灭屏显示，是指在不点亮整块屏幕的前提下，在屏幕的部分区域显示日期、时钟等信息。这样，用户可以不必点亮整块屏幕便可以快速获取到日期、时钟等信息。可以注意到，目前灭屏显示的内容仅能为厂商定制的日期、时钟信息等，内容单一，无法满足用户在不同应用场景中的显示需求。
发明内容
本申请提供的一种灭屏显示方法及电子设备，能够丰富灭屏显示的内容，满足用户在不同应用场景中的显示需求。
为了实现上述目的，本申请实施例提供了以下技术方案：
第一方面、提供一种灭屏显示方法，应用于具有屏幕的电子设备，该方法包括：电子设备亮屏，电子设备运行有第一应用；当电子设备满足灭屏条件时，电子设备灭屏，且显示灭屏画面，记为第一画面，第一画面包含第一应用绘制的第二画面。
需要说明的是，当检测到电子设备满足灭屏条件时，还运行着该第一应用。该第一应用可以在前台运行，也可以在后台运行。也就是说，电子设备在满足灭屏条件时，显示的灭屏画面(即下文的界面B)中包括当前运行的第一应用绘制的第二画面(即下文的界面A)。这样，用户在电子设备显示灭屏画面时，仍然能够及时获取到第一应用的内容，并且有利于降低电子设备的功耗。相比较于现有技术中电子设备在灭屏时只能显示时钟、日期、通知的定制化内容，本申请可以显示更丰富的灭屏内容，满足用户在不同应用场景中的显示需求。
一种可能的实现方式中，在电子设备灭屏，且显示第一画面之前，该方法还包括：电子设备确定第一应用为预设名单上的应用，其中预设名单的应用为允许调用电子设备的常显示AOD功能的应用，第二画面为第一应用调用AOD功能绘制的。
也就是说，电子设备可以通过设置预设名单去对应用(系统应用或三方应用)是否可以调用AOD功能的权限进行管控。该预设名单可以是系统默认设置的，例如是与手机厂商有特定合作关系的应用。该预设名单还可以由用户去设置。那么，手机可以通过系统升级或者单独更新配置库的方式，新增或变更预设名单的内容，即允许(或不允许)调用电子设备的AOD功能的应用名单。
一种可能的实现方式中，该方法还包括：第二画面为第一应用根据电子设备的屏幕能力，调用AOD功能绘制的；其中，电子设备的屏幕能力包括是否支持屏幕自刷 新能力，是否支持多彩显示，是否支持动效，是否支持显示位置定制中一项或多项。
例如，电子设备可以在开机时，或者用户第一次通过系统设置开启AOD功能时，或者当电子设备安装或更新应用时，将电子设备具有的屏幕能力上报给上层的应用。当上层的应用获取电子设备的屏幕能力后，可以根据电子设备的屏幕能力绘制定制化的灭屏画面。这样，便于第一应用根据电子设备实际的屏幕能力进行绘制第二画面。
一种可能的实现方式中，第二画面为第一应用第一界面上部分区域的画面；或者，第二画面包含第一应用第一界面；或者，第二画面为第一应用第一界面的简化版。
其中，第一应用第一界面，用于第一应用在电子设备亮屏时显示的界面。例如，第一应用在亮屏时显示第一界面，第一应用在灭屏时显示该第一界面对应的第二画面时，第二画面可以仅包括第一界面中部分区域的画面，第二画面也可以与第一界面相同或为第一界面的缩小版，或者第二画面为第一界面的简化版，即包含第一界面中的部分内容，并对部分内容进行重新组合或排版等。
一种可能的实现方式中，第二画面包括第一控件，该方法还包括：响应于用户操作第一控件，第二画面变化为第一应用绘制的第三画面。
可以理解的是，由于本申请中，在电子设备灭屏时，仍然可以显示第一应用绘制的第二画面。第二画面中可以包括用于与用户交互的第一控件，那么在电子设备设备灭屏时，用户仍然可以与电子设备进行交互。例如，用户操作第一控件后，响应于该操作，第一应用根据自身的业务逻辑等，绘制新的画面，即第三画面。换言之，响应于该操作，电子设备显示的灭屏画面中的第二画面切换为第三画面。相较于现有技术中，电子设备灭屏时显示的灭屏画面为定制化内容，用户只有点亮并解锁电子设备后才可以操作电子设备，本申请实施例中用户在电子设备灭屏时就可以直接操作第一应用，以获取及时的应用信息，操作更加便利。
一种可能的实现方式中，在电子设备灭屏，且显示第一画面之前，该方法还包括：电子设备根据预设策略，确定第一画面的内容。
也就是说，当手机运行多个应用时，且这多个应用都具有调用AOD功能的能力时，手机可以根据用户设置的显示策略，选择在灭屏画面中显示这多个应用中的一些应用的信息。换言之，手机显示的灭屏画面不一定包含所有的手机当前运行的且具有调用AOD功能的应用的信息。
一种可能的实现方式中，预设策略包括显示AOD应用的内容，或显示第一应用的内容，或显示AOD应用和第一应用的内容；其中，AOD应用的内容包括时间、日期、通知中的一项或多项。
一种可能的实现方式中，电子设备根据预设策略，确定第一画面的内容，具体为：当预设策略为显示第一应用的内容时，电子设备确定第一画面包括第二画面，不包括AOD应用绘制的第四画面；或者，当预设策略为显示AOD应用和第一应用的内容时，电子设备确定第一画面包括第二画面和AOD应用绘制的第四画面。
一种可能的实现方式中，预设策略包括显示应用优先级排名前M个的应用，其中M为大于或等于1的正整数。
一种可能的实现方式中，第一应用为地图类应用，外卖类应用、打车类应用、购物类应用、闪送类应用中任一项。
以地图类应用举例，电子设备亮屏时，显示地图类应用的导航界面。一般，手机需要实时或间隔一段时间获取手机的定位，并根据更新的定位更新导航界面中的数据(例如路线图示404中用户的当前位置、或者导航指示403中的导航信息)。通常，整个导航过程耗费较长的时间。然而，当用户在一段时间内未操作手机时，手机会自动灭屏(即超时灭屏)。那么，用户需要反复地点亮手机屏幕，并且解锁，才可以再次看到导航界面，操作较为繁琐，且用户体验不佳。另外，当手机灭屏后，会控制CPU处于休眠状态，并关闭定位模块以及其他的功能模块。当用户重新点亮手机屏幕，解锁后，手机需要重新开启定位模块，用于获取手机当前的位置，并更新导航界面。可见，在手机灭屏后再次被点亮后，导航界面的刷新效率低。
然而，采用本申请提供的灭屏显示方法后，在手机灭屏时，可以显示包含地图类应用的导航信息的灭屏画面，这样，用户无需进行点亮屏幕以及解锁操作，就能直接获取到导航信息，提升用户体验。另外，还需要说明的是，当手机显示灭屏画面中包含地图类应用的导航界面时，手机并不关闭定位模块。换言之，在手机灭屏时，仍然开启手机的定位模块。那么，当地图类应用在后台运行时，仍可以实时或间隔一段时间获取手机的当前位置，并根据手机的当前位置确定导航界面的图像数据。当导航界面的图像数据未发生变化时，手机保持CPU、GPU等处于休眠状态，以降低手机的功耗。当导航界面的图像数据发生变化时，手机唤醒CPU、GPU等，绘制地图应用新的导航界面，并更新灭屏画面。这样，用户可以直接通过灭屏画面获取地图应用的导航数据，而无需反复点亮屏幕并解锁屏幕，简化用户操作，并且同时降低了手机的功耗。
另外，相对于现有技术中，需要电子设备全程处于亮屏状态，去显示导航界面的技术方案，本申请实施例提供的在手机灭屏时显示导航信息的灭屏画面，有利于节省电子设备的功耗，延长电子设备的待机时长。
第二方面、提供一种灭屏显示方法，应用于安装在电子设备上的第一应用，该方法包括：接收电子设备满足灭屏条件的第一通知；响应于接收到第一通知，第一应用绘制第二画面；其中第二画面用于显示在电子设备在灭屏时显示的第一画面中。
也就是说，当电子设备的AOD功能检测到电子设备满足灭屏条件时，向第一应用发送第一通知。响应于接收到第一通知，第一应用绘制第二画面，其中，第二画面为电子设备灭屏时第一应用需显示的内容。这样，用户可以从电子设备显示灭屏画面中，及时获取到第一应用的内容。这样，既降低了电子设备的功耗，又可以及时获取第一应用更新的内容。
一种可能的实现方式中，第二画面为第一界面上部分区域的画面；或者，第二画面包含第一界面；或者，第二画面为第一界面的简化版。
一种可能的实现方式中，第二画面包括第一控件，该方法还包括：第一应用接收用户操作第一控件的第二通知；响应于接收到第二通知，第一应用绘制第三画面，第三画面用于替换第二画面。
一种可能的实现方式中，还包括：第一应用获取电子设备的屏幕能力，其中，电子设备的屏幕能力包括是否支持屏幕自刷新能力，是否支持多彩显示，是否支持动效，是否支持显示位置定制中一项或多项；第一应用绘制第二画面，具体为：第一应用根据电子设备的屏幕能力，绘制第二画面。
第三方面、提供一种电子设备，包括：处理器、存储器和显示屏，存储器、显示屏与处理器耦合，存储器用于存储计算机程序代码，计算机程序代码包括计算机指令，当处理器从存储器中读取计算机指令，以使得电子设备执行如上述第一方面或第二方面，以及其中任一种可能的实现方式中的灭屏显示方法。
第四方面、提供一种计算机可读存储介质，包括计算机指令，当计算机指令在电子设备上运行时，使得电子设备执行如上述第一方面或第二方面，以及其中任一种可能的实现方式中的灭屏显示方法。
第五方面、提供一种计算机程序产品，当计算机程序产品在计算机上运行时，使得电子设备执行如上述第一方面或第二方面，以及其中任一种可能的实现方式中的灭屏显示方法。
第六方面、提供一种装置，该装置包含在电子设备中，该装置具有实现上述第一方面或第二方面，以及其中任一种可能的实现方式中电子设备行为的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。硬件或软件包括至少一个与上述功能相对应的模块或单元。例如，检测模块或单元、显示模块或单元、以及处理模块或单元等。
第七方面、提供一种芯片系统，包括处理器，当处理器执行指令时，处理器执行如上述各个方面中及其中任一种可能的实现方式中所述的方法。
可以理解地，上述第二方面至第七方面所提供的方法、电子设备、计算机可读存储介质、计算机程序产品、装置、芯片系统所能达到的有益效果可参考上文所提供的第一方面以及任一种可能实现方式中的有益效果，此处不再赘述。

处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
在本申请的一些实施例中，处理器110可以响应于接收到用户执行的锁屏操作，控制电子设备100灭屏，并显示灭屏画面。其中，上述用户执行的锁屏操作，例如可以为用户在电子设备100处于亮屏时按压锁屏键(或电源键)的操作。在另一些实施例中，处理器100还可以在检测到用户在预设时间段内一直未操作电子设备100，并 且电子设备100也未执行特定业务时(如播放视频等)，控制电子设备100灭屏，并显示灭屏画面。
其中，所谓灭屏画面，是指电子设备灭屏时屏幕上显示的内容，灭屏画面一般不占据整个屏幕。也就是说，电子设备100灭屏时，屏幕上至少有部分区域为黑色，不显示内容。灭屏画面可以包括电子设备100在锁屏前运行的应用程序(或者当前在后台运行的应用程序)的信息，例如地图类应用的导航信息(例如，前方转弯信息、变道信息、路况信息、剩余时间等)、外卖类应用的送货信息(例如，骑手当前位置，距离，剩余时间等)、打车类应用的导航信息(例如车辆位置、乘客位置、剩余时间等)、购物类应用、闪送类应用等。
需要说明的是，当电子设备100处于灭屏状态，显示灭屏画面时，处理器110控制电子设备100仅开启与显示上述灭屏画面相关的功能模块，例如显示功能相关的功能模块，定位模块181(用于提供电子设备100的定位位置)等；关闭其他与显示上述灭屏画面无关的功能模块，例如处理器110中的调制解调处理器(Modem)，无线通信模块160中的蓝牙模块、WiFi模块、传感器模块等。
在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。
可以理解的是，本发明实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对电子设备100的结构限定。在本申请另一些实施例中，电子设备100也可以采用上述实施例中不同的接口连接方式，或多种接口连接方式的组合。
充电管理模块140用于从充电器接收充电输入。电源管理模块141用于连接电池142，充电管理模块140与处理器110。电源管理模块141接收电池142和/或充电管理模块140的输入，为处理器110，内部存储器121，屏幕194，摄像头193，和无线通信模块160等供电。
电子设备100的无线通信功能可以通过天线1，天线2，移动通信模块150，无线通信模块160，调制解调处理器以及基带处理器等实现。
定位模块181，用于提供电子设备100的定位。具体的，在电子设备100开启具有定位功能的应用时，电子设备100启动定位模块181用于获取电子设备100实时的定位。其中，具有定位功能的应用例如包括地图类应用、导航类应用、外卖类应用等。
另外需要说明的是，一般，在电子设备100灭屏时，电子设备100仅显示AOD应用定制的灭屏画面时，电子设备100会关闭定位模块。然而，在本申请中，电子设备灭屏时，显示的灭屏画面中可以包括需要定位的应用的信息。因此，电子设备灭屏时，仍然开启定位模块181，能够继续通过定位模块获取电子设备的位置信息。换言之，在电子设备运行有需要定位的应用时，电子设备灭屏，并且待显示的灭屏画面中包含需要定位的应用的信息时，电子设备不关闭定位模块。例如，待显示的灭屏画面 中包含地图类应用的导航功能时，电子设备在灭屏时不关闭定位模块。又例如，待显示的灭屏画面中包含外卖类应用的导航功能时，电子设备在灭屏时不关闭定位模块。
电子设备100通过GPU，屏幕194，以及应用处理器等实现显示功能。GPU为图像处理的微处理器，连接屏幕194和应用处理器。GPU用于执行数学和几何计算，用于图形渲染。处理器110可包括一个或多个GPU，其执行程序指令以生成或改变显示信息。
屏幕194用于显示图像，视频等。屏幕194包括显示面板。显示面板可以采用液晶屏幕(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot light emitting diodes，QLED)等。在一些实施例中，电子设备100可以包括1个或N个屏幕194，N为大于1的正整数。
在本申请中，屏幕194支持AOD功能，用于显示灭屏画面。即，处理器110不点亮整块屏幕194或者不点亮全部的屏幕194，而是控制整块屏幕194的局部或者N个屏幕194中的M个屏幕亮起(M大于或等于1，且小于N)，用于显示灭屏画面，以此降低屏幕194的功耗。需要说明的是，本申请中的AOD功能，也可表达为灭屏显示功能、息屏显示功能、熄屏显示功能、常亮显示功能或其他名称。
示例性的，屏幕194可以为自发光的屏幕。以屏幕为OLED屏幕为例，对自发光的屏幕的工作原理进行简单介绍。其中，OLED屏幕是利用有机电致发光二极管制成的屏幕，与传统的LCD显示方式不同，无需背光灯。OLED屏幕是由非常薄的有机材料涂层和玻璃基板构成，是通过电流驱动有机材料涂层本身来发光的，发的光可为红、绿、蓝、白等单色，同样也可以达到全彩的效果。需要说明的是，OLED屏幕可以通过关闭屏幕的发光单元，来使得屏幕显示黑色的。还需要说明的是，处理器110可以独立控制OLED屏幕中每个像素点来显示内容。因此，处理器110可以点亮一部分像素点的发光单元，用于显示在锁屏前运行的应用程序(或者当前在后台运行的应用程序)的信息，例如导航应用的导航信息、美团应用的导航界面、打车应用的导航界面等。其他未点亮的像素点用于显示黑色画面。
再示例性的，屏幕194也可以采用传统的LCD屏幕。那么，可以对LCD屏幕的背景灯进行改进，使得屏幕194在灭屏显示时，仅点亮其中一部分屏幕，用于显示在锁屏前运行的应用程序(或者当前在后台运行的应用程序)的信息，例如导航应用的导航信息、美团应用的导航界面、打车应用的导航界面等。其他未点亮的区域(其他像素点)显示黑色画面。LCD屏幕具体实现AOD功能的方式不做限定。
电子设备100可以通过ISP，摄像头193，视频编解码器，GPU，屏幕194以及应用处理器等实现拍摄功能。
电子设备100可以通过音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，以及应用处理器等实现音频功能。例如音乐播放，录音等。
按键190包括开机键，音量键等。按键190可以是机械按键。也可以是触摸式按键。电子设备100可以接收按键输入，产生与电子设备100的用户设置以及功能控制有关的键信号输入。马达191可以产生振动提示。马达191可以用于来电振动提示，也可以用于触摸振动反馈。指示器192可以是指示灯，可以用于指示充电状态，电量 变化，也可以用于指示消息，未接来电，通知等。SIM卡接口195用于连接SIM卡。
电子设备100的软件系统可以采用分层架构，事件驱动架构，微核架构，微服务架构，或云架构。本发明实施例以分层架构的Android系统为例，示例性说明电子设备100的软件结构。
图2是本发明实施例的电子设备100的软件结构框图。
分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，将Android系统分为三层，从上至下分别为应用程序层(简称为应用层)，应用程序框架层(简称为框架层)，以及内核层(或称为驱动层)。
上述应用程序层可以包括一系列应用程序包。
如图2所示，应用程序包包括AOD应用，用于在电子设备100灭屏时显示灭屏画面。一些示例中，AOD应用为电子设备100的系统应用，所谓系统应用是指电子设备100在出厂之前预置在电子设备100内的应用。AOD应用可以在电子设备100灭屏时显示系统时间、日历、通知等信息。
应用程序包还可以包括其他系统应用，例如相机，图库，日历，通话，地图，短信息等程序。应用程序包还可以包括三方应用，即可以由用户从例如应用市场下载安装包安装的应用。例如，地图类(如百度地图
Figure PCTCN2022083488-appb-000001
搜狗地图
Figure PCTCN2022083488-appb-000002
)应用、外卖类应用(如美团
Figure PCTCN2022083488-appb-000003
饿了么
Figure PCTCN2022083488-appb-000004
)等。
在现有技术中，电子设备通过AOD应用调用框架层灭屏画面绘制接口(例如画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块)，用于显示灭屏画面。换言之，电子设备显示的灭屏画面中仅包括AOD应用中定制的内容，如系统时间、日历、通知等信息。然而，在本申请中，电子设备的其他系统应用或者三方应用也可以调用框架层中灭屏显示的相关接口，用于显示灭屏画面。换言之，电子设备显示的灭屏画面中也可以包括其他系统应用或者三方应用的内容。
上述应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图2所示，应用程序框架层可以包括AOD服务、AOD原有接口(也称为原生接口)，画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块等。应用程序框架层还可以包括AOD扩展接口、配置库、检测模块、以及检测模块等。
一些示例中，当AOD应用检测到用户的灭屏操作或者检测到用户在预设时间段内未操作电子设备且电子设备未执行特定任务(例如播放视频)，即超时灭屏时，通过AOD服务，AOD原有接口调用画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块中的相应接口，绘制灭屏画面。
在本申请中，三方应用(或其他系统应用)也可以通过AOD服务，AOD扩展接口，调用画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块中的相应接口，绘制包含三方应用(或其他系统应用)信息的灭屏画面。也就是说，原有的灭屏画面绘制接口可以向三方应用或其他系统应用开放，从而实现三方应用或其他系统应用，定制绘制包含三方应用或其他系统应用的信息的灭屏画面。
在一个具体的实施例中，当AOD应用检测到用户的灭屏操作或者超时灭屏时，通过AOD服务通知检测模块。检测模块，用于检测在电子设备当前运行的应用，并向配置库查询当前运行的应用是否具有灭屏显示能力，即是否具有调用灭屏画面绘制接口的权限。其中，配置库可以包括允许调用灭屏画面绘制接口的应用的信息(例如包名)，即配置库中包括灭屏显示的白名单。或者，配置库包括不允许调用灭屏画面绘制接口的应用的信息，即配置库中包括灭屏显示的黑名单。
若具有调用灭屏画面绘制接口的权限，则检测模块通知上层相应的应用(可以是AOD应用、其他系统应用或三方应用)。上层相应的应用则根据自身的业务逻辑确定灭屏画面的内容，向AOD服务发送灭屏画面的绘制请求。
AOD服务将接收到的多个应用的绘制请求发送至决策模块，由决策模块根据预设的策略确定最终绘制的灭屏画面的内容。即，最终绘制的灭屏画面包括哪些应用的内容。例如，仅绘制AOD应用的灭屏画面；绘制其他系统应用或三方应用的灭屏画面；绘制AOD应用的灭屏画面和其他系统应用或三方应用的灭屏画面。其中，绘制其他系统应用或三方应用的灭屏画面，包括绘制全部应用的灭屏画面，或者绘制其中部分应用的灭屏画面。其中，绘制部分应用的灭屏画面可以是绘制优先级最高的一个应用的灭屏画面，或者绘制优先级较高的多个应用的灭屏画面。需要说明的是，决策模块采用的策略可以是电子设备的系统默认设置的，也可以为用户通过电子设备中系统设置项进行设置的，本申请实施例对决策模块采用的具体策略不做具体限定。
而后，决策模块根据AOD应用的绘制请求，通过AOD原有接口调用灭屏显示的相关接口(画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块等)，生成AOD应用的灭屏画面的绘制指令，用于绘制AOD应用在灭屏时需要显示的画面。决策模块根据三方应用或其他系统应用的绘制请求，通过AOD扩展接口调用灭屏显示的相关接口(画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块等)，生成该应用的灭屏画面的绘制指令，用于绘制该应用在灭屏时需要显示的画面。
举个例子，如图3所示，当AOD应用检测的到用户锁屏的操作或者电子设备触发超时灭屏时，检测模块检测到电子设备当前运行的应用包括：应用A(AOD应用)、应用B(其他系统应用)、应用C(其他系统应用)、应用D(三方应用)、应用E(三方应用)。而后，通过查询配置库确定允许调用灭屏显示相关接口的应用有：应用A、应用B、应用C、应用D。需要说明的是，一些示例中，也可以默认AOD应用为允许调用灭屏显示相关接口的应用，即可以不用通过查询配置库即可确定AOD应用为允许调用灭屏显示相关接口的应用，或者，当配置库中没有AOD应用的标识时，也可以确定AOD应用为允许调用灭屏显示相关接口的应用。那么，应用层的应用A、应用B、应用C、应用D分别可以根据自身的业务逻辑请求绘制相应的灭屏画面。决策模块则根据预设的策略确定最终显示的灭屏画面包括应用A(AOD应用)和应用D(如优先级最高的应用)。那么，决策模块确定将应用A和应用D的绘制请求分别发送至AOD原有接口以及AOD扩展接口，进一步调用灭屏画面的绘制接口绘制包括应用A和应用D信息的灭屏画面。
在另一个具体的实施例中，当AOD应用检测到用户的灭屏操作或者超时灭屏时，通过AOD服务向上层的应用发送通知。上层的应用都可以监听到该AOD服务发送的 灭屏通知。具有绘制灭屏画面的应用(例如三方应用或其他系统应用)根据自身的业务逻辑确定灭屏画面的内容，向AOD服务发送灭屏画面的绘制请求。AOD服务将上层应用发送的绘制请求发送给检测模块。检测模块，用于确定该应用是否为电子设备当前运行的应用，并向配置库查询当前运行的应用是否具有灭屏显示能力，即是否具有调用灭屏画面绘制接口的权限。
若具有调用灭屏画面绘制接口的权限，则检测模块允许三方应用(或其他系统应用)，调用画面绘制模块、画面配置模块、画面色彩模块、以及画面合成模块中的相应接口，绘制包含三方应用(或其他系统应用)信息的灭屏画面。而后，将各个应用绘制好的灭屏画面发送至决策模块，由决策模块根据预设的策略确定最终绘制的灭屏画面的内容。即，最终绘制的灭屏画面包括哪些应用的内容。其余内容可参考前一实施例的相关内容的描述。
需要说明的是，这里三方应用或其他系统应用调用灭屏画面绘制接口的流程仅为示例，本申请实施例对具体的调用流程不做具体限定。
在另外一些示例中，AOD原有接口和AOD扩展接口可以集成在一起，或者，AOD原有接口和AOD扩展接口还可以与AOD服务集成在一起，本申请实施例对此不做具体限定。
内核层是硬件和软件之间的层。内核层包括屏幕自刷新(panel self refresh，PSR)能力、低功耗显示能力、亮度调整能力、位置定制能力、动效能力、色彩能力、定位能力等。
其中，屏幕自刷新(panel self refresh，PSR)能力，是指电子设备可以根据待显示的画面是否变化，确定是否刷新屏幕的能力。在一些示例中，电子设备的屏幕可以集成屏幕内存，即屏幕带随机存取存储器(random access memory，RAM)，用于存储屏幕待显示的图像数据。当检测到屏幕待显示的下一帧图像数据与上一帧图像数据一致时，可以将图像数据的传输电路进行挂起操作。也就是说，当屏幕显示的灭屏画面在一段时间内维持不变时，电子设备可以控制CPU、GPU等进入休眠状态，从而降低功耗。当屏幕内存接收到与上一帧图像数据不同的的图像数据时，再恢复图像数据的传输电路，唤醒CPU、GPU等，绘制新的灭屏画面。并且，重复之前的检测过程(检测前后一帧图像数据是否一致)，以便完成下一次将图像数据的传输电路挂起的操作。
其中，低功耗显示能力包括切换屏幕的供电模式的能力，将屏幕从正常(Normal)模式切换至休眠(doze)模式，从而降低电子设备在灭屏显示时的功耗。低功耗显示能力还包括切换触摸屏的工作模式。一般电子设备的屏幕为触摸屏，将屏幕的触控的工作模式由活跃(active)模式切换至空闲(idle)模式，以降低电子设备在灭屏显示时的功耗。
其中，亮度调整能力，包括电子设备在灭屏时，检测周围环境光的亮度值，并根据周期环境光的亮度值动态调整灭屏画面的亮度，以便用户在任何环境下也可以看到清晰的灭屏画面。另外一些示例中，根据屏幕的亮度的强度值可以划分为多档工作模式(例如两档或三挡)，则当电子设备灭屏显示时，可以采用亮度的强度值较低的一档工作模式。
其中，位置定制能力(也称为显示位置定制能力)，是指其他系统应用或三方应用在绘制灭屏画面时，可以指定自身应用绘制的灭屏画面在屏幕中的显示位置，以及灭屏画面的大小等。例如，指定显示在屏幕的中央，显示在AOD定制画面的下方等。例如，屏幕自带RAM的大小决定屏幕可以显示的整个灭屏画面大小，而其中每个应用的灭屏画面不得大于整个灭屏画面的最大值。
其中，动效能力，是指电子设备灭屏时，可以对灭屏画面中的内容设置动效，例如包括进入动效、灭屏画面内容发生变化时的动效，退出灭屏画面的动效等。
其中，色彩能力，是指电子显示灭屏画面时，控制灭屏画面的色彩的能力。
其中，定位能力，是指提供电子设备的定位的能力。具体的，在电子设备开启具有定位功能的应用时，电子设备启动定位模块用于获取电子设备实时的定位。其中，具有定位功能的应用例如包括地图类应用、导航类应用、外卖类应用等。
需要说明的是，一般，在电子设备灭屏时，电子设备仅显示AOD应用定制的灭屏画面时，电子设备会关闭定位模块。然而，在本申请中，电子设备灭屏时，显示的灭屏画面中可以包括需要定位的应用的信息。因此，电子设备灭屏时，仍然开启定位模块181，能够继续通过定位模块获取电子设备的位置信息。换言之，在电子设备运行有需要定位的应用时，电子设备灭屏，并且待显示的灭屏画面中包含需要定位的应用的信息时，电子设备不关闭定位模块。
可选的，内核层还可以包括屏幕能力上报能力等。其中，屏幕能力上报能力，包括在电子设备灭屏显示之前，将电子设备与灭屏显示相关的能力(低功耗显示能力、亮度调整能力、位置能力、动效能力、色彩能力等)上报给应用层的应用，以便应用层的应用根据电子设备具有的屏幕能力，绘制相应的灭屏画面。
以下实施例中所涉及的技术方案均可以在具有上述硬件架构和软件架构的电子设备100中实现。下文，先以电子设备100是手机，且以地图应用为例，对本方案进行示例性说明。
如图4中(1)所示，用户在使用手机时，可以通过操作手机的主屏幕界面中的应用图标启动应用。例如，响应于用户在手机的主屏幕界面中点击地图应用对应的图标401，手机开启启动地图应用，并显示地图应用的主界面。当然，用户也可以通过语音命令开启地图应用，或者通过其他方式(例如在即时通信应用中的点击位置信息的链接等)开启地图应用。本申请对启动地图应用的方式不做限定。进一步的，用户可以在地图应用的主界面上进行一系列操作，例如输入目的地，选择路线(例如常规路线)等，并点击“开始导航”的控件，手机进入如图4中(2)所示的导航界面402。在导航界面402中，显示有导航指示403，路线图示404，以及一些功能控件(例如退出、继续当前导航、更多等)。一般，手机需要实时或间隔一段时间获取手机的定位，并根据更新的定位更新导航界面中的数据(例如路线图示404中用户的当前位置、或者导航指示403中的导航信息)。通常，整个导航过程耗费较长的时间，例如20分钟，1小时，4小时等。然而，当用户在一段时间内未操作手机时，手机会自动灭屏(即超时灭屏)。那么，用户需要反复地点亮手机屏幕，并且解锁，才可以再次看到导航界面402，操作较为繁琐，且用户体验不佳。另外，当手机灭屏后，会控制CPU处于休眠状态，并关闭定位模块以及其他的功能模块。当用户重新点亮手机屏幕，解锁后， 手机需要重新开启定位模块，用于获取手机当前的位置，并更新导航界面。可见，在手机灭屏后再次被点亮后，导航界面的刷新效率低。
在本申请中，在手机灭屏时，可以显示包含地图应用的导航信息的灭屏画面，这样，用户无需进行点亮屏幕以及解锁操作，就能直接获取到导航信息，提升用户体验。
另外，相对于现有技术中，需要电子设备全程处于亮屏状态，去显示导航界面，本申请实施例提供的在手机灭屏时显示导航信息的灭屏画面，有利于节省电子设备的功耗，延长电子设备的待机时长。
在一些实施例中，用户可以在系统设置中开启地图应用调用绘制灭屏画面的权限。例如，如图5中(1)所示，响应于用户在手机的主屏幕界面中操作“设置”应用的图标501，手机显示如图5中(2)所示的设置界面502。设置界面502中包括“AOD”的设置项503。响应于用户操作“AOD”的设置项503，手机显示如图6中(1)所示的AOD功能的设置界面601。该设置界面601中显示有AOD功能的开关控件。在开启AOD功能后，还可以对AOD功能进行进一步设置，如设置允许调用AOD系统的应用(包括除AOD应用外的其他系统应用以及三方应用)、设置灭屏画面的字体、字体大小、以及设置显示策略等。例如，响应于用户操作控件允许调用AOD功能的应用控件602，手机显示如图6中(2)所示的应用选择界面603。一些示例中，默认AOD应用具有调用AOD功能。选择界面603中还可以显示手机已安装的其他应用的标识(如名称或图标等)。用户可以选择相应的应用为允许调用AOD功能的应用。例如响应于用户在选择界面603中选择地图应用的操作，手机显示如图6中(3)所示的界面604，即地图应用被勾选中。换言之，用户已授权地图应用调用AOD功能的权限。当然，用户还可以授权其他应用，或者该方法修改应用调用AOD功能的权限。
在用户在界面604中点击“确定”控件后，手机存储用户设置的允许调用AOD功能的应用的信息。例如，结合上述图2所示的结构示意图，手机框架层中配置库中存储有用户设置的允许调用AOD功能的应用名单。在另一些实施例中，允许调用手机的AOD功能的应用也可以是系统默认设置的，例如是与手机厂商有特定合作关系的应用。那么，手机可以通过系统升级或者单独更新配置库的方式，新增或变更允许调用手机的AOD功能的应用名单。
此后，当用户使用手机开启地图应用，并进入如图4中(2)所示的导航界面402后，若用户执行锁屏操作，或手机超时灭屏时，手机可以将地图应用切换至后台运行，并灭屏。在手机灭屏时，手机显示包含地图应用的导航信息的灭屏画面。例如，手机灭屏时，可以显示如图7中(1)所示的灭屏画面1，其中灭屏画面1中包含AOD应用定制的时间、日期、通知等信息，还包含地图应用中的部分信息(如导航指示信息)。或者，手机灭屏时显示如图7中(2)所示的灭屏画面2。其中，灭屏画面2中包含
AOD应用定制的时间、日期、通知等信息，还包含地图应用中导航界面。其中，灭屏画面2中包含的地图应用中导航界面可以是地图应用原导航界面的缩小版，也可以是地图应用原导航界面的简化版。
在一种具体实现方式中，结合上述图2所示的结构示意图，若用户执行锁屏操作，或手机超时灭屏时，手机框架层的检测模块检测到手机当前运行的应用有地图应用。并且，进一步的，手机从配置库中查询到地图应用为允许调用AOD功能的应用。因 此，检测模块通知地图应用，并且地图应用通过AOD扩展接口调用灭屏画面的相关接口(如画面绘制模块、画面配置模块、画面色彩模块、画面合成模块)绘制相应的灭屏画面，例如绘制图7中(1)中所示的导航指示，或者绘制图7中(2)中所示的导航指示、实时地图以及功能控件等。
另外，还需要说明的是，当手机显示包含地图应用的导航界面时，手机并不关闭定位模块。换言之，在手机灭屏时，仍然开启手机的定位模块。那么，当地图应用在后台运行时，仍可以实时或间隔一段时间获取手机的当前位置，并根据手机的当前位置确定导航界面的图像数据。当导航界面的图像数据未发生变化时，手机保持CPU、GPU等处于休眠状态，以降低手机的功耗。当导航界面的图像数据发生变化时，手机唤醒CPU、GPU等，绘制地图应用新的导航界面，并更新灭屏画面。这样，用户可以直接通过灭屏画面获取地图应用的导航数据，而无需反复点亮屏幕并解锁屏幕，简化用户操作，并且同时降低了手机的功耗。
在另一些实施例中，用户还可以设置AOD功能中的显示策略。也就是说，当手机运行多个应用时，且这多个应用都具有调用AOD功能的能力时，手机可以根据用户设置的显示策略，选择在灭屏画面中显示这多个应用中的一些应用的信息。换言之，手机显示的灭屏画面不一定包含所有的手机当前运行的且具有调用AOD功能的应用的信息。
例如，如图8中(1)所示的AOD功能的设置界面601中还可以包括显示策略的设置项605。响应于用户操作显示策略的设置项605，手机可以显示如图8中(2)所示的显示策略的设置界面801。其中，显示策略的设置界面801中可以包括三种策略，分别为策略1至策略3。
其中，策略1为仅显示AOD应用，即手机显示的灭屏画面仅包括AOD应用定制的信息，例如时间、日期和通知。比如，手机在灭屏时，运行有AOD应用和地图应用，则灭屏画面仅包括AOD应用定制的时间、日期和通知，不包括地图应用的信息。需要说明的是，当手机开启AOD功能后，手机一直运行有AOD应用。
策略2为仅显示非AOD应用，即手机显示的灭屏画面仅包括除AOD应用外的其他具有调用AOD功能的系统应用，以及具有调用AOD功能的三方应用的信息，例如这里的地图应用。可以理解的是，采用策略2后，手机显示的灭屏画面中可以包括一个或多个符合条件的应用的信息。比如，手机在灭屏时，运行有AOD应用和地图应用，则灭屏画面包括地图应用的信息，不包括AOD应用定制的时间、日期和通知。
策略3、显示AOD+非AOD应用，即手机显示的灭屏画面包括AOD应用定制的时间、日期和通知，以及其他具有调用AOD功能的系统应用和三方应用的信息。可以理解的是，采用策略3后，手机显示的灭屏画面中可以包括一个或多个符合条件的应用的信息。比如，手机在灭屏时，运行有AOD应用和地图应用，则灭屏画面包括地图应用的信息，以及AOD应用定制的时间、日期和通知。
可以理解，策略1至策略3是互斥的策略，也就是说，策略1至策略3中只能选择其一。当然，当选中策略2或策略3后，策略2或策略3还可以和其他的策略进行组合。例如，根据策略2或策略3确定多个符合条件的应用时，还可以进一步确定从多个符合条件的应用中再刷新出一个或多个应用。例如，优先显示优先级较高的特定 数量(例如1个、3个)的应用。其中应用的优先级可以为系统默认设置的，也可以为用户手动设置的(例如通过图8中(2)所述的界面801中的控件803进行设置)，对此不做限定。又例如，优先显示最近使用的特定数量(例如1个、3个)的应用。最近使用的应用可以认为是在手机灭屏前最后从前台运行切换到后台运行的应用。比如，用户开启应用1后，在未关闭应用1的情况下，又开启了应用2，当应用2在前台运行时(用户可以与应用2进行交互)，手机灭屏。此时，应用2切换至后台运行，可以认为应用2相较于应用1，为用户最近使用的应用。又例如，接着上述例子，若用户在开启应用2后，又切换回应用1，即，应用1在前台运行时，手机灭屏。此时，应用1再次切换至后台运行，则认为应用1相较于应用2，为用户最近使用的应用。又例如，优先显示最近启动的应用。一般手机记录有各个应用的启动时间，根据各个应用的启动时间确定最近启动的应用。
上述策略1至策略3为本申请实施例提供的一种显示策略的举例，当然也可以采用其他任何的显示策略。
例如，手机也可以显示如图8中(3)所示的显示策略的设置界面802。用户可以选择显示优先级较高的一个或多个应用，也可以选择显示最近使用的一个或多个应用，还可以选择显示最近启动的一个或多个应用，或者显示全部应用。这里的选择全部应用，是包括手机灭屏时运行的应用，且具有调用AOD功能的全部应用。
又例如，手机的灭屏画面也可以优先显示三方应用或其他系统应用的信息。换言之，在手机在灭屏时，当运行有能够调用AOD功能的其他系统应用或三方应用时，显示其他系统应用或三方应用的信息，不显示AOD应用的信息。当手机没有运行能够调用其他系统应用或三方应用时，显示AOD应用的信息。
总之，本申请对设置策略的方法以及具有的策略内容不做限定。
在用户设置完具体的显示策略后，响应于用户在界面801或界面802中点击“确定”控件，手机存储用户设置的显示策略。例如，结合上述图2所示的结构示意图，手机框架层中决策模块中存储有用户设置的显示策略。在另一些实施例中，显示策略也可以是系统默认设置的。
在一种具体实现方式中，结合上述图2所示的结构示意图，若用户执行锁屏操作，或手机超时灭屏时，手机框架层的检测模块检测到手机当前运行的应用有多个，例如运行的应用有地图应用、微信

应用的显示需求，调用内核层中相应的能力，如低功耗显示能力、亮度调整能力、位置定制能力、动效能力以及色彩能力中的一项或多项，最终通过屏幕显示出包含地图应用和饿了么应用信息的灭屏画面。
在又一些实施例中，其他系统应用或三方应用可以默认设置灭屏时的显示内容，显示位置，显示方式等。用户也可以在系统设置时，在开启某个应用调用AOD功能权限时，一并设置该应用在灭屏时显示内容，显示位置，以及显示方式等。或者，用户也可以在各个应用的设置界面中设置该应用在灭屏时显示内容，显示位置，以及显示方式等。本申请实施例对此不做限定。当然，也可由应用的开发方定制化设置应用的灭屏画面，包括显示内容，显示位置，显示方式等。
其中，应用的显示内容包括显示该应用的哪些内容。例如，可以设置地图应用在灭屏时显示简要信息，如图7中(1)所示，地图应用仅显示导航指示。也可以设置地图应用在灭屏时显示详细信息，如图7中(2)所示，地图应用整个导航界面，包括导航指示以及地图等。换言之，应用开发方或用户可以定制应用在灭屏时显示的内容。
其中，应用的显示位置，是指手机灭屏时，该应用的内容显示在屏幕的什么位置，例如显示在AOD定制信息的下方，屏幕的中央，屏幕的下方等。当手机在灭屏时显示有多个应用的信息，有利于用户对各个应用的信息的显示位置进行排列。
其中，应用的显示方式，包括该应用的显示内容是否采用动效，采用什么样的动效，显示内容使用的色彩模式(黑白、彩色等)。
在又一些实施例中，电子设备还可以在开机时，或者用户第一次通过系统设置开启AOD功能时，或者当电子设备安装或更新应用时，将电子设备具有的屏幕能力上报给上层的应用。其中，电子设备具有的屏幕能力包括但不限于：屏幕是是否集成有RAM(即是否支持屏幕自刷新能力，能够根据配置的时间片和时长自动刷新画面)，以及屏幕集成的RAM的大小(影响着灭屏画面的整体大小)，是否支持多彩显示等。当上层的应用获取电子设备的屏幕能力后，可以根据电子设备的屏幕能力绘制定制化的灭屏画面。
如图9所示，为本申请实施例提供的一种灭屏显示方法的流程示意图。该灭屏显示方法包括：
S901、电子设备亮屏。
S902、当电子设备满足预设条件时，电子设备检测当前运行的应用。
其中，预设条件是指电子设备灭屏的条件，包括检测到用户执行的锁屏操作，或者检测到用户在预设时间段内一直未操作电子设备，且电子设备也未执行特定任务(播放视频的任务)。换言之，当检测到电子设备满足灭屏的条件后，电子设备检测当前运行的应用。
在一些实施例中，当电子设备启动某个应用时，会记录该应用的运行信息，包括应用的标识、应用启动时间、应用运行的状态(前台运行或后台运行)等。因此，电 子设备可以根据记录的应用的运行信息，确定电子设备当前运行的应用。需要说明的是，当前运行的应用包括电子设备前台运行的应用和电子设备后台运行的应用。当然，在其他一些实施例中，电子设备也可以仅检测电子设备前台运行的应用。也就是说，可以认为电子设备前台运行的应用为用户当前最为关注的应用，那么在电子设备灭屏时会优先或仅显示该前台运行的应用。
需要说明的是，电子设备可以启动并同时运行多个应用，为用户提供不同的业务功能。其中，手机同时运行多个应用是指，手机已启动多个应用，该多个应用未关闭，且手机未删除该多个应用占用的内存等资源，多个应用同时在后台占用内存等资源；而并不要求多个应用程序同时在前台与用户交互。例如，在电子设备亮屏时，用户启动有微信
Figure PCTCN2022083488-appb-000016
应用、视频应用、地图应用。其中，地图应用为前台运行的应用，电子设备的屏幕显示有地图应用的界面，用户可以通过该地图应用的界面与电子设备进行交互。微信
Figure PCTCN2022083488-appb-000017
应用和视频应用为后台运行的应用，电子设备的屏幕未显示有微信
Figure PCTCN2022083488-appb-000018
应用的界面，未显示有视频应用的界面。当然，用户可以切换应用，例如将微信
Figure PCTCN2022083488-appb-000019
应用切换为前台运行的应用，此时不会杀死之前的前台运行的地图应用，而是将地图应用切换到后台运行。
还需要说明的是，上述电子设备启动的应用，可以是用户通过操作主界面中应用图标，开启的应用。也可以是，电子设备自动启动的应用。例如，当用户在系统设置中开启电子设备的灭屏功能时，电子设备可以自动开启AOD应用。
S903、电子设备检测到当前运行有第一应用。
其中，AOD应用为电子设备的一个系统应用，为电子设备提供AOD功能的应用。一般，电子设备开启AOD功能后，电子设备会自动开启AOD应用，由AOD应用在电子设备灭屏时，绘制AOD应用定制的灭屏画面，例如时间、日期、通知等信息。
此外，电子设备还可以检测到当前运行的其他系统应用或三方应用，即第一应用。如前所述，第一应用可以为前台运行的应用，也可以是后台运行的应用。第一应用的数量为一个或多个。
S904、电子设备将第一应用，与预设应用名单中的应用进行比对。
其中，预设应用名单中的应用，为具有调用AOD功能的权限的应用的名单。该预设应用名单包括具有调用AOD功能的其他系统应用或三方应用的应用标识信息、应用的权限信息等。例如：应用的权限信息包括应用可以调用的具体功能的信息，例如，屏幕的自刷新能力、低功耗显示能力、灭屏画面的亮度调整能力、灭屏画面的位置定制能力、灭屏画面的动效能力、灭屏画面的色彩能力等。在一些示例中，预设名单中也可以包括显示某应用时，是否开启定位模块的定位能力等。当该应用为需要定位的应用，例如地图类应用、外卖类应用、打车类应用、购物类应用等，开启电子设备的定位能力。
若第一应用与预设应用名单中的应用匹配，则电子设备允许第一应用调用AOD功能，若第一应用与预设应用名单中的应用不匹配，则电子设备不允许第一应用调用AOD功能。
预设应用名单中的应用可以为电子设备默认设置的，例如是与手机厂商有特定合作关系的应用。预设应用名单中的应用也可以为用户通过例如系统设置进行设置的。 本申请对此不做限定。
当然，预设应用名单中的应用，也可以为不具有调用AOD功能的权限的应用的名单。那么，若第一应用与预设应用名单中的应用不匹配，则电子设备允许第一应用调用AOD功能，反正，电子设备不允许第一应用调用AOD功能。下文以预设应用名单中的应用，为具有调用AOD功能的权限的应用的名单为例进行说明。
S905、当第一应用与预设应用名单中应用匹配时，第一应用调用AOD功能绘制画面A。其中，画面A为第一应用在电子设灭屏时显示的内容。
其中，画面A可以包括第一应用当前所在界面中的部分区域的内容，也可以包含第一应用当前所在界面中的全部内容。其中，第一应用当前所在界面，是指第一应用切换到后台运行前，最后在前台显示的界面。以地图应用的导航界面为例，画面A可以仅包含部分重要的导航信息，例如前方转弯信息、变道信息、路况信息、剩余时间等。画面A也可以是地图应用的导航界面，或者为地图应用导航界面的缩小版或简化版等。或者，以外卖类应用的送货界面为例，画面A可以仅包含骑手的当前位置、剩余的到货时间。画面A也可以是外卖类应用的送货界面，或者为送货界面的缩小版或简化版等。
示例性的，若预设应用名单中还包括应用的权限，则电子设备根据预设应用名单中的权限，允许第一应用调用AOD功能中相关能力。
在一种实现中，如图2所示，第一应用(为其他系统应用或三方应用)可以通过AOD服务、AOD扩展接口绘制第一应用的灭屏画面。需要说明的是，AOD应用此时也可以通过AOD服务、AOD原有接口绘制AOD应用的灭屏画面，一般包含时间、日期、通知信息。
S906、电子设备根据预设的显示策略，确定画面B。其中，画面B为电子设备在灭屏时显示的内容。
其中，预设的显示策略可以是电子设备默认设置的，也可以由用户在系统设置中进行设置。具体的显示策略的内容可参考前文描述，这里不再赘述。
在一些实施例中，当电子设备接收到两个或两个以上的应用绘制的灭屏画面时，电子设备会根据预设的显示策略确定画面B中包括哪些应用绘制的灭屏画面。
如图10所示，第一应用和AOD应用分别将绘制请求发送至电子设备的决策模块，当决策模块确定第一应用为预设的应用名单上的应用时，确定第一应用能够调用AOD接口。其中，AOD接口可以为AOD扩展接口，也可以为AOD原有接口。进一步的，决策模块根据预设的显示策略，确定是否画面B的内容。
例如，若显示策略为画面B仅包含AOD应用绘制的灭屏画面，决策模块则允许AOD应用通过AOD接口调用框架层的AOD能力，进一步调用驱动层的能力，最终调用器件显示AOD应用绘制的灭屏画面。决策模块不允许第一应用调用框架层的AOD能力。
又例如，若显示策略为画面B仅包含第一应用绘制的灭屏画面，决策模块则允许第一应用通过AOD接口调用框架层的AOD能力，进一步调用驱动层的能力，最终调用器件显示第一应用绘制的灭屏画面。决策模块不允许AOD应用调用框架层的AOD能力。在其他一些示例中，若第一应用包含多个应用时，显示策略也可以设置为根据 应用优先级优先显示某个第一应用绘制的灭屏画面。例如，当决策模块确定电子设备运行有地图应用和微信
Figure PCTCN2022083488-appb-000020
应用，且这两个应用均在预设应用的名单上。然而，地图应用的优先级大于微信
Figure PCTCN2022083488-appb-000021
应用。那么，决策模块可以优先显示地图应用绘制的灭屏画面，而不显示微信
Figure PCTCN2022083488-appb-000022
应用绘制的灭屏画面。其中，应用的优先级可以是电子设备默认设置的，也可以由用户在系统设置或各个应用的设置界面中进行设置。
又例如，若显示策略为画面B仅包含第一应用绘制的灭屏画面，画面B包含AOD应用和第一应用绘制的灭屏画面。那么，决策模块则允许第一应用和AOD应用通过AOD接口调用框架层以及内核层的相关能力，并显示包含AOD应用和第一应用绘制的灭屏画面。在其他一些示例中，显示策略还可以进一步设置为优先显示第一应用绘制的灭屏画面。换言之，第一应用的优先级大于AOD应用。那么，当电子设备确定当前运行的应用为第一应用，且第一应用在预设名单上，则决策模块确定优先显示第一应用绘制的灭屏画面，不显示AOD应用绘制的灭屏画面。当电子设备确定当前运行的应用仅有AOD应用，或者电子设备还运行有其他应用，但其他应用不在预设应用名单上，则决策模块可以确定显示AOD应用绘制的灭屏画面。
需要说明的是，本申请实施例对显示策略的具体内容不做限定。
S907、电子设备灭屏，并显示画面B。其中，画面B中包含画面A。
在一些示例中，画面A中可以包括用于与用户交互的控件，例如按钮控件、选择控件、文本控件等。换言之，当电子设备灭屏时，用户通过画面A中的控件，对第一应用进行操作。再换言之，响应于用户在画面A对控件的操作，第一应用可以绘制新的画面，用于替换当前的画面A。
需要说明的是，当第一应用为具有定位功能的应用时，在电子设备灭屏后，电子设备还保持定位模块处于开启状态，以便电子设备在灭屏时还能够获取电子设备的定位，便于第一应用根据电子设备的新位置绘制新的灭屏画面。
其中，具有定位功能的应用，例如为开启导航功能时地图类应用，开启导航功能的外卖类应用(例如骑手的送货导航界面)，开启导航功能的打车类应用等。
换言之，在手机灭屏时，可以显示包含地图应用的导航信息的灭屏画面，这样，用户无需进行点亮屏幕以及解锁操作，就能直接获取到导航信息，提升用户体验。
综上，本申请实施例提供的灭屏方法，可以在电子设备灭屏时，显示包含除AOD应用之外的其他应用的信息。这样，用户可以在电子设备灭屏时获取更多重要的及时的应用信息。进一步的，其他应用绘制的灭屏画面中还可以包括用于与用户交互的控件，便于用户在电子设备灭屏时与该应用进行交互，从而扩展了电子设备灭屏时的使用场景。
本申请实施例还提供一种芯片系统，如图11所示，该芯片系统包括至少一个处理器1901和至少一个接口电路1902。处理器1901和接口电路1902可通过线路互联。例如，接口电路1902可用于从其它装置(例如电子设备100的存储器)接收信号。又例如，接口电路1902可用于向其它装置(例如处理器1901)发送信号。示例性的，接口电路1902可读取存储器中存储的指令，并将该指令发送给处理器1901。当所述指令被处理器1901执行时，可使得电子设备执行上述实施例中的电子设备100(比如，手机)执行的各个步骤。当然，该芯片系统还可以包含其他分立器件，本申请实施例 对此不作具体限定。
