具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种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这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对 重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
用户使用电子设备时可能会在室外或强光下使用。这种情况下，电子设备需要将屏幕的亮度提高到一定水平，才能保证用户可以看清屏幕，提供良好的显示效果。
但是，能够满足在室外或强光下使用的屏幕亮度水平往往较高，与之匹配的，需要提供足够大的驱动电流驱动屏幕。虽然在大电流下屏幕的亮度得到了提升，但也会导致电子设备整机温度快速升高。
目前所使用的方案，在屏幕亮度保持较高亮度时，电子设备的整机温度会在很短的时间内达到温度保护阈值，触发高温保护机制。高温保护机制触发后，会强制降低屏幕亮度，使其限制到较低水平，而这个亮度水平往往无法满足在室外或强光下使用，严重影响用户的使用体验。
对此，本申请提供了一种屏幕亮度调整方法，应用于电子设备，包括：当所述电子设备处于高亮场景时，获取所述电子设备的设备温度；当所述设备温度大于或等于第一温度阈值时，按照线性或非线性逐步降低电子设备的屏幕亮度，直至所述设备温度与第二温度阈值相同或相近，第二温度阈值大于所述第一温度阈值。
本申请中，由于在电子设备处于高亮场景且达到第一温度阈值时就开始介入调整电子设备的屏幕亮度，可以使电子设备的亮度逐渐降低，直至设备温度与第二温度阈值相同或相近。在这个过程中，电子设备的屏幕亮度可以始终保持在一个相对较高的亮度水平，不会出现断崖式的亮度变化，给用户带来更好的使用体验。

图4是本申请一实施例提供的屏幕亮度调整方法的流程示意图。
参考图4，屏幕亮度调整方法包括：
S401、检测到电子设备处于高亮场景，若是，则执行S402，若否则继续检测。
一些可能的实现方式中，检测电子设备是否处于高亮场景，可以通过检测电子设备的环境亮度或获取电子设备的屏幕亮度实现。
作为示例，参考图1中的场景，以及图2中示出的电子设备结构，当电子设备中的环境光传感器180L获取到的环境亮度大于或等于第一亮度阈值时，即可确定电子设备是否处于高亮场景。
例如，假设第一亮度阈值为10000勒克斯(lx)对于图1中的场景，若环境光传感器180L采集到的环境亮度的照度为12000lx，即可以确定电子设备处于高亮场景。
另一个示例中，如果环境亮度不高(如仅有5000lx)，但是通过人工设置或者某些应用强制将屏幕亮度调高。这种情况下，可以获取电子设备的屏幕的亮度，当屏幕亮度大于或等于第二亮度阈值时，即可确定电子设备是否处于高亮场景。
例如，假设第二亮度阈值为1000尼特(nit)，若获取电子设备的屏幕的亮度为1300nit，即可以确定电子设备处于高亮场景。
S402、获取电子设备的设备温度。
一些可能的实现方式中，参考图2中示出的电子设备结构，电子设备可以通过温度传感器180J获取设备温度，温度传感器180J可以设置在电子设备的壳体内侧、处理器附近或屏幕内侧等位置。或者，也可以设置多个温度传感器180J，将多个温度传感器180J采集到温度的平均值作为设备温度。
S403、检测到设备温度大于或等于第一温度阈值，若是，则执行S404，若否则继续检测。
一些可能的实现方式中，第一温度阈值也可以成为预警温度，即电子设备的温度提升至第一温度阈值时，需要介入对屏幕亮度进行调节，以保证电子设备不会因为屏幕高亮度而迅速提升设备温度，触发温控保护。作为示例，第一温度阈值可以是预先设置的，第一温度阈值可以小于温控触发温控保护的温度，例如，第一温度阈值可以是30℃、33℃或35℃等。
图5是本申请一实施例提供的屏幕亮度调整方法中屏幕亮度、设备温度以及时间的变化曲线示意图。
参考图5，其中，t1时刻电子设备的屏幕亮度开始提升，在t2时刻检测到电子设备 处于高亮场景。这个情况下，开始执行S402、S403。当在t3时刻检测到设备温度大于或等于第一温度阈值T1时，即确定需要开始介入，对屏幕亮度进行调整。
S404、根据电子设备的环境温度，获取对应的亮度调节函数。
一些可能的实现方式中，由于电子设备所处的环境温度不同，电子设备的设备温度提升的速率也不同。所以，可以根据电子设备的环境温度，获取对应的亮度调节函数。
其中，电子设备的环境温度可以通过设置于电子设备表面的温度传感器获取。或者，也可以通过天气预报应用程序获取。再或者，也可以通过与电子设备通信连接的，具有温度测量功能的智能设备获取。例如，若电子设备所处的环境中包括与电子设备通信连接的智能空调、智能温度计、智能空气净化器等智能设备，则电子设备可以请求智能设备反馈环境温度，以获取电子设备的环境温度。
作为示例，对于每一种电子产品，可以预先获取电子设备在不同环境温度下的平衡亮度系数。平衡亮度系数为平衡屏幕亮度与最大屏幕亮度的比值，当电子设备的屏幕亮度保持在平衡屏幕亮度时，设备温度与所述第二温度阈值相同或相近。
即平衡亮度系数K平可以通过公式一表示：
K平＝L平/Lmax  (公式一)
其中，L平为平衡屏幕亮度，Lmax为最大屏幕亮度。
然后，获取该电子产品在不同环境温度下的亮度调节函数。
一些可能的实现方式中，亮度调节函数可以输出亮度调节系数K，亮度调节系数与Lmax的乘积即为屏幕的目标亮度L。
作为示例，参考图5，亮度调节系数K可以通过公式二或公式三计算：

其中，公式二为线性亮度调节函数，通过公式二中的K对屏幕亮度调节，可以实现屏幕亮度的线性调节，公式三为非线性亮度调节函数，通过公式三中的K对屏幕亮度调节，可以实现屏幕亮度的非线性调节。
则屏幕的目标亮度L可以通过公式四计算：
L＝K*Lmax  (公式四)
其中，T为电子设备的设备温度，T2为第二温度阈值，即屏幕亮度保持在平衡屏幕亮度时的温度。T3为触发温控保护的温度。
以室温25℃为例，T1可以是35℃、T2可以是40℃、T3可以是42℃，
作为示例，参考图5，当在t3时刻检测到设备温度大于或等于第一温度阈值T1时，可以根据当前电子设备的环境温度，获取该电子设备的亮度调节函数(即公式二或公式三)然后，根据公式二或公式三执行S405。
S405、根据亮度调节函数逐步降低电子设备的屏幕亮度。
一些可能的实施方式中，参考S404中的示例，根据公式二或公式三调节屏幕亮度时，可以先设置温度传感器(sensor)的阈值。例如，可以将第一温度阈值T1设置为35℃。当温度传感器获取到的温度大于或等于35℃时，将获取到的设备温度T发送给 显示引擎。
显示引擎根据接收到的温度T，根据参考公式二或公式三进行实时亮度调节系数K的计算。
其中，显示引擎可以是软件显示引擎也可以是硬件显示引擎。例如，软件显示引擎可以是框架层(Framework)中的显示引擎服务。
作为示例，当电子设备为手机时，Lmax可以是1500nit。当在25°室温时，若手机负载正常，则屏幕亮度为1000nit时，可以使手机的设备温度稳定在40℃(T2)附近。则T1可以设置为35℃。根据上述示例中的公式，可以计算得到K平为0.667。当设备温度高于T1时，温度传感器可以每5秒上报一次温度，电子设备的设备温度可以是温度传感器上报的最近5次温度的平均值。
作为示例，电子设备还可以每隔预设温度更新一次亮度调节系数K。例如，可以在设备温度T达到T1(35℃)后，每升高0.5℃更新一次亮度系数K。即，当T从35℃升至35.5℃及以上时，可以更新亮度调节系数K。若从35℃升至35.4℃，由于升温不到0.5℃，则不更新亮度调节系数K。
其中，以上计算步骤可以在Framework中的显示引擎服务中进行。当计算得到亮度系数K后，根据K和Lmax算出目标亮度L。然后，将目标亮度下发给控制屏幕亮度的线程，并结合亮度切换模块，采用渐变的方式平缓切换屏幕亮度。
例如，可以经过亮度控制服务“lightService”下发亮度至内核层的背光驱动程序(Backlight Driver)，通过Backlight Driver平滑调整亮度。
其中，lightService是安卓系统中的一个服务，用于控制屏幕亮度。lightService允许使用函数来设置设备的屏幕亮度。例如，可以通过传递一个亮度值的参数，或者使用预定义的亮度常量来调整屏幕亮度。本申请中，即使用公式二或公式三计算得到的K与Lmax相乘，得到目标亮度L，将目标亮度L作为亮度值的参数来调整屏幕亮度。
而Backlight Driver则用于控制屏幕的背光亮度。Backlight Driver提供平滑调节的功能，可以进行平滑的亮度过渡，以避免亮度调节的明显变化。Backlight Driver接收到目标亮度L后，根据目标亮度L与当前显示亮度之间背光亮度的差别，进行平滑调节，控制屏幕的背光亮度按照目标亮度L进行显示。
S406、检测到设备温度与第二温度阈值相同或相近，若是，则执行S407，若否则继续执行S405。
S407、保持电子设备的屏幕亮度。
一些可能的实施方式中，参考图5，当在t4时刻，检测到设备温度与第二温度阈值相同或相近，即确定电子设备的屏幕亮度与温度达到平衡，可以保持电子设备的屏幕亮度，这个情况下，电子设备的设备温度可以保持在一个合适的温度(T2)。
其中，设备温度与第二温度阈值相近，包括：设备温度与第二温度阈值的差值小于或等于预设阈值。或，设备温度与第二温度阈值的温度差小于或等于预设比例。
例如，第二温度阈值为40℃，预设阈值为0.2℃。则设备温度为40℃时，确认设备温度与第二温度阈值相同。当设备温度为39.8℃至40.2℃时，确认设备温度与第二温度阈值相近。
再例如，第二温度阈值为40℃，预设比例为1％。则设备温度为40℃时，确认设备温度与第二温度阈值相同。当设备温度为39.6℃(40℃*99％)至40.4℃(40℃*101％) 时，确认设备温度与第二温度阈值相近。
图6是本申请另一实施例提供的屏幕亮度调整方法的流程示意图。
参考图6，其中，S401至S407与图4中示出的流程相同，在此不做赘述。
在S407之后，屏幕亮度调整方法还包括：
S408、检测到设备温度大于或等于第三温度阈值，若是，则执行S409，若否则继续检测。
S409、逐步降低电子设备的芯片性能。
S410、检测到设备温度与第二温度阈值相同或相近，若是，则执行S407，若否则继续检测。
一些可能的实施方式中，当保持电子设备的屏幕亮度时，对电子设备进行操作，导致电子设备功耗增加，或者环境温度发生较大变化，均可能导致电子设备的设备温度急剧上升。
在这个情况下，若检测到设备温度大于或等于第三温度阈值(即触发温控保护的温度)，则可以执行S409，以降低设备功耗，进而降低电子设备的设备温度。
作为示例，逐步降低电子设备的芯片性能，例如，可以降低屏幕的画面刷新频率，即降低GPU渲染帧率，或者还可以降低芯片的运算需求，例如降低电子设备上各个传感器的采样频率，无线网络、近场通讯、蓝牙的传输速率，关闭系统后台的应用计算等。通过降低芯片的计算负荷，关闭芯片的部分硬件计算单元，可以实现降低芯片的和主要元器件的发热，避免温度持续提升。
其中，S410中的方法与S406中相同，在此不做赘述。
在本实施例中，通过在检测到设备温度大于或等于第三温度阈值时，逐步降低电子设备的芯片性能，直至所述设备温度与第二温度阈值相同或相近。可以在电子设备的设备温度过高时，即保证屏幕亮度处于一个较高的水平，又保证电子设备的温度可以降至一个合理的区间，为用户提供了更好的使用体验。
