具体实施方式
下面将结合本申请以下实施例中的附图，对本申请实施例中的技术方案进行详尽描述。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请实施例中，“一个或多个”是指一个、两个或两个以上；“和/或”，描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
以下，先对本申请实施例中涉及的部分用语进行解释说明，以便于本领域技术人员容易理解。
本申请实施例涉及的至少一个，包括一个或者多个；其中，多个是指大于或者等于两个。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请实施例涉及的应用程序(application，app)，可以简称应用，为能够实现某项或多项特定功能的软件程序。通常，电子设备中可以安装多个应用，例如，即时通讯类应用、视频类应用、音频类应用、图像拍摄类应用等等。其中，即时通信类应用，例如可以包括短信应用、微信(WeChat)、WhatsApp Messenger、连我(Line)、照片分享(instagram)、Kakao Talk、钉钉等。图像拍摄类应用，例如可以包括相机应用(系统相机或第三方相机应用)。视频类应用，例如可以包括Youtube、Twitter、抖音、爱奇艺，腾讯视频等等。音频类应用，例如可以包括酷狗音乐、虾米、QQ音乐等等。以下实施例中提到的应用，可以是电子设备出厂时已安装的应用，也可以是用户在使用电子设备的过程中从网络下载或其他电子设备获取的应用。

衰变损耗累计电路可以用于监听显示驱动电路发送给显示屏的所述显示数码流，根据所述显示数码流确定显示屏上每个子块的平均显示亮度和显示时长，然后根据每个子块的平均显示亮度和显示时长，确定每个子块的累计损耗值。具体的，显示屏上子块的划分过程，以及每个子块的累计损耗值的确定过程将在后文介绍。

核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心库。应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理，堆栈管理，线程管理，安全和异常的管理，以及垃圾回收等功能。
系统库可以包括多个功能模块。例如：表面管理器(surface manager)，媒体库(media libraries)，三维图形处理库(例如：OpenGL ES)，2D图形引擎(例如：SGL)等。
表面管理器用于对显示子系统进行管理，并且为多个应用程序提供了2D和3D图层的融合。
媒体库支持多种常用的音频，视频格式回放和录制，以及静态图像文件等。媒体库可以支持多种音视频编码格式，例如:MPEG4，H.264，MP3，AAC，AMR，JPG，PNG等。
三维图形处理库用于实现三维图形绘图，图像渲染，合成，和图层处理等。
2D图形引擎是2D绘图的绘图引擎。
此外，系统库还可以包括显示/渲染服务、节能显示控制服务。其中，显示/渲染服务用于确定显示数码流，该显示数码流中包括显示屏上的每个像素单元(下文可以简称像元)的显示信息，显示信息可以包括显示亮度、显示时间、文字信息、图像信息等。节能显示控制服务用于从备选显示区域中确定最佳显示区域。

下面结合本申请实施例的显示控制方法，示例性说明电子设备的软件以及硬件的工作流程。
作为一种示例，系统库中显示/渲染服务将显示数码流发送给内核层的显示驱动，以使显示驱动来驱动显示屏在不同的像素单元上显示对应的显示信息。内核层中的衰败损耗值累计程序监听显示/渲染服务发送给显示区域的显示数码流，确定显示数码流中每个子块对应的显示亮度和显示时间。衰败损耗值累计程序根据每个子块的显示亮度和显示时间，计 算每个子块的累计损耗值。系统库中的节能显示控制服务根据预设分辨率将显示屏划分为多个备选显示区域，每个备选显示区域中包括多个子块。节能显示控制服务读取衰败损耗值累计程序确定的每个子块的累计损耗值，进而确定每个备选显示区域中包括的所有子块的累计损耗值的总和，即每个备选显示区域的累计损耗值。节能显示控制服务确定多个备选显示区域中累计损耗值最低的最佳显示区域，并将该最佳显示区域的显示位置发送给显示驱动，以使显示驱动来驱动显示屏上的最佳显示区域显示信息。
参见图4为，本申请实施例提供的显示控制方法的流程示意图，该方法可以由图1或图2所示的电子设备执行。如图4所示，该方法的流程包括：
401：将显示屏划分为多个子块，每个子块的分辨率为n*n，n为大于或等于1的整数，每个子块的分辨率小于所述显示屏的分辨率。
需要说明的是，每个子块的分辨率n*n可以是电子设备出厂时默认设置好的，也可以是用户自定义的，本申请实施例不作限定。应理解，电子设备设置每个子块的分辨率n*n后，可以根据显示屏的分辨率、以及n*n将显示屏划分为多个子块。举例来说，每个子块的分辨率n*n为3*3，若显示屏的分辨率为12*12，则显示屏被划分为4个子块，每个子块的分辨率为3*3。
402：确定每个子块的累计损耗值。
以下实施例介绍402的两种可能的实现方式。
方式1：
电子设备可以确定每个子块的显示时长Δt，以及每个子块在该显示时长Δt内的平均显示亮度c。那么第i个子块在Δt时长内的损耗值可以通过如下公式获得：
Figure PCTCN2020114091-appb-000011
其中，Δt i是第i个子块的显示时长；Δd i是第i个子块在Δt i时长内的损耗值，c i是第i个子块在Δt i时长内的平均显示亮度；α是显示屏的半亮度寿命与初始亮度乘积值，其中，初始亮度值可以是显示屏出厂之后，首次被点亮时的亮度值；半亮度寿命是显示屏从初始亮度降到初始亮度的一半时需要的时长。可以理解的是，初始亮度值和半亮度寿命可以是预先存储在电子设备中的，因此，α可以是预先存储在电子设备中的。
需要说明的是，上述过程只是介绍了计算第i个子块在Δt i时长内的损耗值，那么第i个子块从首次点亮开始的累计损耗值可以通过如下公式得到：
d i＝d 0i+Δd i
其中，d i是第i个子块从首次点亮开始的累计损耗值，d 0i是第i个子块在Δt i之前的历史累计损耗值。换言之，第i个子块的累计损耗值是一阶段一阶段的计算的，d 0i是在Δt i之前的多个时间段内的损耗值的总和，每个时间段内的损耗值的计算方式与上述Δd i的计算方式相同。
因此，通过上述方式可以确定每个子块的累计损耗值，该累计损耗值即每个子块从首次点亮时刻开启的总损耗值。
需要说明的是，方式1中没有考虑每个子块中不同的颜色的像素单元，处理方式较为简单。
方式2：
需要说明的是，该方式2中考虑显示屏上的多种基础颜色像素单元(简称像元)，例如红色(red)、绿色(green)、蓝色(blue)三种基础颜色像素单元。也就是说，每个子块 中可以包括红色、绿色、蓝色三种像元。电子设备可以确定每个子块中每种颜色像元在显示时长Δt内的损耗值。
例如，第i个子块中红色像元在Δt i时长内的损耗值可以通过如下公式获得：
Figure PCTCN2020114091-appb-000012
其中，Δt r,i是第i个子块中红色像元的显示时长；Δd r,i是第i个子块中红色像元在Δt r,i时长内的损耗值，c r,i是第i个子块中红色像元在Δt r,i时长内的平均显示亮度；α r是显示屏中红色像元的半亮度寿命与初始亮度乘积值，其中，初始亮度值可以是显示屏出厂之后，首次被点亮时的红色像元的亮度值；半亮度寿命是显示屏上红色像元从初始亮度衰减至初始亮度的一半时所需的工作时长。可以理解的是，红色像元的初始亮度值和半亮度寿命可以是预先存储在电子设备中的，即α r是预先存储在电子设备中的。
又如，第i个子块中绿色像元在Δt i时长内的损耗值可以通过如下公式获得：
Figure PCTCN2020114091-appb-000013
其中，Δt g,i是第i个子块中绿色像元的显示时长；Δd g,i是第i个子块中绿色像元在Δt g,i时长内的损耗值，c g,i是第i个子块中绿色像元在Δt g,i时长内的平均显示亮度；α g是显示屏中绿色像元的半亮度寿命与初始亮度乘积值，其中，初始亮度值可以是显示屏出厂之后，首次被点亮时的绿色像元的亮度值；半亮度寿命是显示屏上绿色像元从初始亮度衰减至初始亮度的一半时所需的工作时长。可以理解的是，绿色像元的初始亮度值和半亮度寿命可以是预先存储在电子设备中的，即α g是预先存储在电子设备中的。
又如，第i个子块中蓝色像元在Δt i时长内的损耗值可以通过如下公式获得：
Figure PCTCN2020114091-appb-000014
其中，Δt b,i是第i个子块中蓝色像元的显示时长；Δd b,i是第i个子块中蓝色像元在Δt b,i时长内的损耗值，c b,i是第i个子块中蓝色像元在Δt b,i时长内的平均显示亮度；α b是显示屏中蓝色像元的半亮度寿命与初始亮度乘积值，其中，初始亮度值可以是显示屏出厂之后，首次被点亮时的蓝色像元的亮度值；半亮度寿命是显示屏上蓝色像元从初始亮度衰减至初始亮度的一半时所需的工作时长。可以理解的是，蓝色像元的初始亮度值和半亮度寿命可以是预先存储在电子设备中的，即α b是预先存储在电子设备中的。
可以理解的是，第i个子块在Δt i时长内的损耗值是第i个子块中蓝色像元在Δt i时长内的损耗值、绿色像元在Δt i时长内的损耗值、红色像元在Δt i时长内的损耗值的总和，即，第i个子块在Δt i时长内的损耗值通过如下公式得到：
Figure PCTCN2020114091-appb-000015
需要说明的是，上述过程只是介绍了计算第i个子块在Δt i时长内的损耗值，那么第i个子块从首次点亮开始的累计损耗值可以通过如下公式得到：
d i＝d 0i+Δd i
其中，d i是从第i个子块首次点亮之后的累计损耗值，d 0i是第i个子块在Δt i之前的历史累计损耗值。因此，第i个子块的累计损耗值是一阶段一阶段的计算的，d 0i是多个时间 段内的损耗值的总和，每个时间段内的损耗值的计算方式与上述Δd i的计算方式相同。
因此，通过上述方式可以确定每个子块的累计损耗值。
需要说明的是，与前述方式1不同的是，方式2中考虑了每个子块中的不同的颜色像元，使得每个子块的累计损耗值计算更加准确。
403，根据预设分辨率，确定K个备选显示区域，每个备选区域包括M个子块，M为大于或等于1的整数；K为大于或等于1的整数，K个备选显示区域占满整个显示屏。
需要说明的是，预设分辨率可以是电子设备出厂之前默认设置好的，也可以是用户自定义的。
示例性的，以显示屏的分辨率是1280*1024、预设分辨率是w×h为例，w大于或等于n小于或等于1280，h大于或等于n小于或等于1024。电子设备将显示屏划分为多个备选显示区域，每个备选显示区域的分辨率为w×h。一种可能的实现方式为，如图5所示，电子设备的显示屏被划分为多个子块，电子设备以w×h的预览框(分辨率)从左到右(或者从上到下)依次确定备选显示设备，预览框从左到右的移动步长可以是默认设置好的，例如可以是一个子块的长度。因此，电子设备可以确定出多个备选显示区域，每个备选显示区域包括M个子块。
404，确定每个备选显示区域的平均累计损耗值。
在402中，确定出每个子块的累计损耗值，所以，第j个备选区域的平均累计损耗值可以通过如下公式确定：
Figure PCTCN2020114091-appb-000016
其中，i＝N0,…,M0
其中，D j是第j个备选显示区域的平均累计损耗值；d i是第j个备选显示区域包括的第i个子块的累计损耗值。因此，第j个备选显示区域中所有子块的累计损耗值的总和的平均值，即该第j个备选显示区域的平均累计损耗值。
405，确定每个备选显示区域中累计损耗值最高的子块。
即，d j,max＝max(d i)，i大于或等于1小于或等于M，其中，d j,max是第j个备选显示区域中包括的M个子块中损耗值最高的子块的累计损耗值，d i是第j个备选显示区域中包括的第i个子块的累计损耗值。假设第j个备选显示区域中包括3个子块，则确定这3个子块中累计损耗值最高的子块。
406，确定多个备选显示区域中平均累计损耗值最小，和/或，备选显示区域中累计损耗值最高的子块的累计损耗值小于预设阈值的备选显示区域为最佳显示区域。
一种可能的方式为，由于404中，确定了每个备选显示区域的平均累计损耗值，所以，电子设备可以确定多个备选显示区域中确定平均累计损耗值最小的备选显示区域为最佳显示区域。
另一种可能的方式为，由于405中，确定了每个备选显示区域中累计损耗值最高的子块，电子设备可以在多个备选显示区域中选择最佳显示区域，该最佳显示区域中累计损耗值最高的子块的累计损耗值小于其它备选显示区域中累计损耗值最高的子块的累计损耗值。
其它可能的实现方式为，综合考虑每个备选显示区域的平均累计损耗值，以及每个备 选显示区域中累计损耗值最高的子块。示例性的，电子设备可以通过如下公式，确定最佳显示区域：
min{β*D j+(1-β)d j,max}，j＝1…K；
其中，D j是第j个备选显示区域的平均累计损耗值；d j,max是第j个备选显示区域中累计损耗值最高的子块的累计损耗值，β为加权系数，是预先存储在电子设备中的取值。
需要说明的是，本申请实施例提供的显示控制方法中，一方面，选定的最佳显示区域平均衰变损耗值较小，以使整块显示屏上不同区域的损耗均衡；另一方面，避免选定的显示区域内有个别子块的损耗已达到最大，即将失效，可以防止出现屏幕坏点。
407，将当前显示界面适配显示于最佳显示区域内。
其中，适配显示可以包括，将当前显示界面缩小到最佳显示区域内显示，或者，将当前显示界面中的部分界面在最佳显示区域内显示，其它部分界面不显示，部分界面可以是用户指定的，或者是当前显示界面中的app自适应确定的；或者，根据最佳显示区域尺寸，在当前显示界面选择合适尺寸的控件进行显示，以适配最佳显示区域的尺寸，所述控件包括按钮、文字、图标、图片等元素或其组合；或者，将当前显示界面内的布局调整，以适配最佳显示区域的尺寸；其中，布局可以是当前显示界面中的按钮、文字、图标、图片等的布局。示例性的，当前显示界面中包括第一应用的应用窗口时，第一应用可以调整应用窗口内的布局以适配最佳显示区域，或者，第一应用可以自适应的调整应用窗口的分辨率/尺寸以适配最佳显示区域的尺寸。
示例1：
参见图6中的(a)所示，电子设备处于折叠形态时，主屏或者副屏显示信息。电子设备确定主屏或副屏上的最佳显示区域，例如图中灰色显示区域为最佳显示区域。以主屏或副屏显示锁屏界面为例，电子设备可以在该最佳显示区域中显示固定信息，固定信息可以是电量、时间、天气等信息。电子设备可以在其它区域(灰色区域以外的其它区域)显示动态信息，动态信息可以是新收到的消息、来电信息等，或者其它区域可以熄灭。
需要说明的是，锁屏界面中通常包括时间、电量等固定信息，且该固定信息在锁屏界面中的固定区域显示，该固定区域长时间显示信息的话会快速损耗，导致所述固定区域损耗严重，进而导致整个显示屏的损耗不均衡。本申请实施例提供的技术方案，电子设备可以将固定信息显示在计算出的最佳显示区域，由于最佳显示区域是从多个备选显示区域中选择出的累计损耗最小的显示区域，所以可以避免显示屏上不同区域损耗不均衡的情况出现。
此外，由于电子设备确定最佳显示区域时考虑每个备选显示区域的平均累计损耗值，由于每个备选显示区域中的每个子块的累计损耗值随时间在变化，所以不同时间，每个备选显示区域的平均累计损耗值是不同的。因此，不同时间，电子设备确定出的最佳显示区域可能是不同的。示例性的，电子设备某一段时间内在上半个显示区域(上半个显示区域是最佳显示区域)，显示固定信息，在另一段时间内可能在下半个显示区域(下半个显示区域是最佳显示区域)显示固定信息。
示例2：
参见图6中的(b)所示，电子设备处于折叠形态。主屏或副屏显示第一界面，该第一界面例如为主界面或某个应用的显示界面。电子设备确定主屏或副屏上的最佳显示区域， 例如图中灰色显示区域为计算出的最佳显示区域，电子设备可以将主屏或副屏上的第一界面缩小，然后将缩小后的第一界面显示在该最佳显示区域中。由于计算出的最佳显示区域的显示面积小于整个显示屏的显示面积，所以，在最佳显示区域显示缩小后的第一界面时，在最佳显示区域之外的其它区域可以不显示任何信息，例如熄灭。
示例3：
参见图7中的(a)所示，电子设备处于展开形态。假设电子设备当前显示第一界面，第一界面中包括第一应用的应用窗口，电子设备根据第一应用的类型确定第一应用适合竖屏显示还是适合横屏显示，若第一应用适合竖屏显示，例如第一应用是微信应用，则电子设备以w×h的预览框选择备选显示区域，w小于h，所以，选择出的最佳显示区域呈竖屏，例如图中灰色显示区域为计算出的最佳显示区域，则在该最佳显示区域中显示缩小后的第一界面，在最佳显示区域之外的其它显示区域不显示任何信息，例如熄灭，或者，在最佳显示区域中显示缩小后的第一界面，在最佳显示区域之外的其它显示区域显示键盘触控区域。
又或者，电子设备可以根据当前显示界面中包括的显示内容，决定最佳显示区域的尺寸/分辨率。其中，显示内容可以包括当前显示界面中的图片、视频、文字等。例如，当前显示界面是视频播放界面，则确定最佳显示区域呈横屏显示。
在该示例中，电子设备可以根据当前显示界面中包括的应用的类型，和/或，显示内容，决定w与h的关系，然后确定呈横屏的最佳显示区域，还是呈竖屏的最佳显示区域。也就是说，电子设备根据当前显示界面中的应用和/或显示内容确定合适的尺寸/分辨率，然后基于该尺寸/分辨率去搜索最佳显示区域，其中确定最佳显示区域的过程在前文已经描述过，在此不重复赘述。
示例4：
参见图7中的(b)所示，电子设备处于展开形态。假设电子设备当前显示第一界面，第一界面中包括第一应用的应用窗口，电子设备根据第一应用的类型确定第一应用适合竖屏显示还是适合横屏显示，若第一应用适合横屏显示，例如第一应用是腾讯视频，则电子设备以w×h的预览框选择备选显示区域，w大于h，则选择出的最佳显示区域呈横屏，例如图中灰色显示区域为计算出的最佳显示区域，则在该最佳显示区域中显示缩小后的第一界面，在最佳显示区域之外的其它显示区域不显示任何信息，例如熄灭，或者，在最佳显示区域中显示缩小后的第一界面，在最佳显示区域之外的其它显示区域显示键盘触控区域。
需要说明的是，本申请实施例提供的显示控制方法可以在电子设备激活“节能显示”功能的情况下使用。例如，电子设备在设置应用中提供“节能显示”功能的激活控件，当该控件被激活时，电子设备启动“节能显示”功能，执行本申请实施例提供的显示控制方法。又如，电子设备在满足预设条件时，也可以自动启动“节能显示”功能。其中，预设条件可以是电子设备当前的剩余电量小于预设电量，或者，电子设备当前的总功耗大于预设功耗等等。
以图7中的(b)为例，电子设备处于展开形态，全屏显示第一界面，当电子设备检测到当前剩余电量小于预设电量时，自动确定最佳显示区域，在该最佳显示区域显示缩小后的第一界面。也就是说，电子设备在全屏显示的情况下，检测到剩余电量较少时，可以自动缩小显示区域，即缩小后的显示区域即通过上述过程确定出的最佳显示区域。通过这种方式，节省电能，提升电池续航能力，且均衡显示屏上不同区域的损耗。
需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。本发明实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。例如，上述实施例中，第一获取单元和第二获取单元可以是同一个单元，也不同的单元。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。

在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。所述计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行所述计算机程序指令时，全部或部分地产生按照本申请实施例所述的流程或功能。所述计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。所述计算机指令可以存储在计算机可读存储介质中，或者从一个计算机可读存储介质向另一个计算机可读存储介质传输，例如，所述计算机指令可以从一个网站站点、计算机、服务器或数据中心通过有线(例如同轴电缆、光纤、数字用户线)或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。所述计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可用介质集成的服务器、数据中心等数据存储设备。所述可用介质可以是磁性介质，(例如，软盘、硬盘、磁带)、光介质(例如DVD)、或者半导体介质(例如固态硬盘)等。
