技术领域
本申请属于电子设备的显示屏技术领域，具体涉及一种显示屏的刷新频率调整方法和电子设备。
背景技术
通常来说，电子设备的显示屏在工作时，往往是根据一定的刷新频率(也可称为驱动频率)来控制像素发光，即像素在工作时并不是常亮的，而是在刷新频率的驱动下不断发生亮暗变化，基于视觉暂留现象，在刷新频率达到一定条件时，人眼通常无法感知这种闪烁，但是仍然会对人眼造成一定影响，如刷新频率越低，对人眼或者大脑的影响越大，会加速视觉疲劳。另外，刷新频率还与电子设备的功耗存在关联，如刷新频率越高则电子设备的功耗越高。
现有电子设备的显示屏的刷新频率通常是一个固定值，这导致后续在使用电子设备时，显示屏的刷新频率往往难以灵活地平衡降低视觉疲劳和降低电子设备功耗的需求。
发明内容
本申请实施例的目的是提供一种显示屏的刷新频率调整方法和电子设备，能够解决显示屏的刷新频率往往难以灵活地平衡降低视觉疲劳和降低电子设备功耗的需求的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全 部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的显示屏的刷新频率调整方法进行详细地说明。
图1是本申请实施例提供的显示屏的刷新频率调整方法的流程示意图。显示屏的刷新频率调整方法可以包括如下步骤：
步骤101，获取电子设备的显示屏所关联的视觉影响因素，视觉影响因素包括屏幕像素的亮度值、电子设备所处环境的当前光环境参数、用户特征信息和应用程序类型中的至少一项。
通常来说，电子设备的显示屏对用户视觉的影响通常与显示屏所显示的内容、电子设备所处的环境、用户本身的身体素质和/或行为习惯、使用电子设备的时长等因素相关，视觉影响因素可以指示这些与显示屏影响用户视觉相关的因素。例如，视觉影响因素可以包括屏幕像素的亮度值、电子设备所处环境的当前光环境参数、用户特征信息和应用程序类型中的至少一项。
换而言之，视觉影响因素可以是屏幕像素的亮度值、电子设备所处环境的当前光环境参数、用户特征信息和应用程序类型中的任意一项，视觉影响因素也可以包括上述四者之间的任意组合。这样，可以通过考虑屏幕像素的亮度值、电子设备所处环境的当前光环境参数、用户特征信息和应 用程序类型这四个因素的影响，来确定目标刷新频率，有效保证了调整显示屏的刷新频率的准确性和全面性。
在步骤101中，当电子设备的显示屏工作时，即电子设备的显示屏并未处于熄屏状态，而是正在显示一些内容时，可以获取电子设备的显示屏所关联的视觉影响因素。
步骤102，根据视觉影响因素，将显示屏的刷新频率调整为与视觉影响因素相匹配的目标刷新频率。
其中显示屏的刷新频率也可以称为显示屏的驱动频率，用于体现显示屏每秒画面被刷新的次数。在步骤102中，可以根据视觉影响因素确定预设的刷新频率调整规则，然后可以依据预设的刷新频率调整规则，确定与视觉影响因素相匹配的目标刷新频率，进而可以将显示屏的刷新频率调整为目标刷新频率。预设的刷新频率调整规则可以是指当显示屏对用户人眼的影响越小时，目标刷新频率则越低，当显示屏对用户人眼的影响越大时，目标刷新频率则越高的规则。这样，可以在显示屏对用户人眼的影响较大时，提高显示屏的刷新频率，优先满足降低用户视觉疲劳的需求，在显示屏对用户人眼的影响较小时，可以认为此时不必要降低用户视觉疲劳，故可以降低显示屏的刷新频率，以满足电子设备节约功耗的需求，从而到达动态调整显示屏的刷新频率，更灵活地平衡降低视觉疲劳和降低电子设备功耗的需求的目的。
可以理解的是，若视觉影响因素为屏幕像素的亮度值，屏幕像素的亮度值越低，如黑色的背景部分，其对用户人眼的影响越小，此时目标刷新频率越低；反之，屏幕像素的亮度值越高，其对用户人眼的影响越大，此时目标刷新频率越高。
若视觉影响因素为电子设备所处环境的当前光环境参数，当电子设备所处环境的当前光环境参数对用户人眼的刺激越大时，显示屏对用户人眼的影响反而较小，此时目标刷新频率越低；反之，当电子设备所处环境的 当前光环境参数对用户人眼的刺激越小时，显示屏对用户人眼的影响反而增大，此时目标刷新频率越高。
若视觉影响因素为用户特征信息，其中用户特征信息可以包括用户年龄、用户使用电子设备的频率等。可以根据用户特征信息划分不同的用户人群，并显示屏对不同的用户人群人眼的影响程度，确定对应的目标刷新频率。换而言之，可以根据不同的用户人群采用不同的目标刷新频率。
若视觉影响因素为应用程序类型，可以根据不同的应用程序采用不同的目标刷新频率。例如，对于视频播放类型、电子书类型等单次使用时长较长的应用程序，可以采用较高的目标刷新频率；对于拨号、短信等单次使用时长较短的应用程序，可以采用较低的目标刷新频率。
例如，以视觉影响因素包括屏幕像素的亮度值为例，预设的刷新频率规则可以体现为多个预设亮度值与刷新频率的预设对应关系，例如亮度值L1对应刷新频率F1，亮度值L2对应刷新频率F2，亮度值L3对应刷新频率F3……其中，屏幕像素的数量通常为多个，且根据显示屏所显示的内容，每个屏幕像素的亮度值可能存在区别。基于此，在一些示例中，可以根据各屏幕像素对应的亮度值，计算屏幕像素的平均亮度值，然后可以将平均亮度值与多个预设亮度值进行匹配，如此时平均亮度值匹配为亮度值L1，则可以将刷新频率F1确定为目标刷新频率，换而言之，此时可以将显示屏的刷新频率调整为刷新频率F1。
在本申请实施例中，显示屏的刷新频率调整方法能够获取电子设备的显示屏所关联的视觉影响因素，视觉影响因素包括屏幕像素的亮度值、电子设备所处环境的当前光环境参数、用户特征信息和应用程序类型中的至少一项；根据视觉影响因素，将显示屏的刷新频率调整为与视觉影响因素相匹配的目标刷新频率。这样，可以通过视觉影响因素动态调整显示屏的刷新频率，避免出现因固定的刷新频率过高而导致电子设备的功耗较大， 或者因固定的刷新频率过低而导致用户的视觉易疲劳的情况，动态的目标刷新频率能够更灵活地平衡降低视觉疲劳和降低电子设备功耗的需求。
在一些实施例中，在视觉影响因素包括屏幕像素的亮度值的情况下，上述步骤102可以包括如下步骤：
根据屏幕像素的亮度值，将显示屏的区域划分为N个亮度子区域，每个亮度子区域中的屏幕像素的亮度值处于同一预设亮度值区间内，N为正整数；
根据各亮度子区域中的屏幕像素的亮度值所处的预设亮度值区间，以及亮度值区间与刷新频率的预设对应关系，确定N个亮度子区域一一对应的N个子目标刷新频率；
将第一亮度子区域的刷新频率调整为第一子目标刷新频率，第一亮度子区域为N个亮度子区域中的任一亮度子区域，第一子目标刷新频率为N个子目标刷新频率中与第一亮度子区域对应的子目标刷新频率。
在本实施例中，视觉影响因素可以包括屏幕像素的亮度值，可以将显示屏的区域根据屏幕像素的亮度值进行划分，以显示屏的显示内容为8bit的图像为例，屏幕像素的亮度值的取值范围可以为0～255，可以根据预设的划分规则将屏幕像素按照其亮度值所处0～L1、L1～L2、L2～L3……等多个预设亮度值区间中的某一区间，从而进行归类划分区域，得到N个亮度子区域，可以理解的是，每个亮度子区域中的屏幕像素的亮度值均处于同一预设亮度值区间内。
可以根据各亮度子区域中的屏幕像素的亮度值所处的预设亮度值区间，以及亮度值区间与刷新频率的预设对应关系，确定N个亮度子区域一一对应的N个子目标刷新频率。示例地，屏幕像素的亮度值处于0～L1区间内的亮度子区域可以对应刷新频率F1；屏幕像素的亮度值处于L1～L2区间内的亮度子区域可以对应刷新频率F2；屏幕像素的亮度值处于L2～L3区间内的亮度子区域可以对应刷新频率F3……其中，刷新频率F的取值范围 可以为1HZ～10000HZ，具体取值可以根据实际情况进行选择，此处不作具体限定。例如，L1可以为50，F1可以为200HZ；L2可以为100，F1可以为1000HZ；L3可以为150，F1可以为1440HZ……。
可以根据各亮度子区域中的屏幕像素的亮度值所处的预设亮度值区间，确定N个亮度子区域一一对应的N个子目标刷新频率，即目标刷新频率可以包括N个子目标刷新频率，可以根据N个子目标刷新频率来调整显示屏的刷新频率。示例地，可以将第一亮度子区域(N个亮度子区域中的任一亮度子区域)的刷新频率调整为第一亮度子区域对应的第一子目标刷新频率。换而言之，显示屏的不同亮度子区域可以应用不同的刷新频率。
可以理解的是，当显示屏的显示内容发生改变的情况下，可以重新根据屏幕像素的亮度值划分显示屏的亮度子区域。
这样，可以通过将显示屏的区域根据屏幕像素的亮度值识别并划分呈不同的亮度子区域，针对不同亮度子区域应用不同的子目标刷新频率，从而实现降低视觉疲劳和节约电子设备功耗的平衡。
在一些实施例中，在视觉影响因素包括电子设备所处环境的当前光环境参数的情况下，上述步骤102可以包括如下步骤：
根据当前光环境参数，以及光环境参数与刷新频率的预设对应关系，将显示屏的刷新频率调整为与当前光环境参数相匹配的目标刷新频率。
在本实施例中，视觉影响因素可以包括电子设备所处环境的当前光环境参数，电子设备中可以设置环境光感知模块，环境光感知模块可以用于探测并记录电子设备周边的当前光环境参数。其中，当前光环境参数可以包括当前环境光亮度、当前环境光色温和当前环境光色度值中的至少一项。
可以根据当前光环境参数，以及光环境参数与刷新频率的预设对应关系，确定与当前光环境参数相匹配的目标刷新频率，并将显示屏的刷新频率调整为目标刷新频率。可以理解的是，若当前光环境参数指示当前环境 光对用户人眼的刺激越大，此时显示屏对用户人眼的影响反而较小，则此时显示屏可以应用较低的刷新频率；反之，若电子设备所处环境的当前光环境参数指示当前环境光对用户人眼的刺激越小，此时显示屏对用户人眼的影响反而增大，则此时显示屏可以应用较高的刷新频率。
例如，当前光环境参数在AL1以下时，可以将目标刷新频率确定为刷新频率F1；当前光环境参数在AL1和AL2之间时，可以将目标刷新频率确定为刷新频率F2；当前光环境参数在AL2和AL3之间时，可以将目标刷新频率确定为刷新频率F3……。其中，F的取值范围可以为1HZ～10000HZ。当前光环境参数AL可以是当前环境光亮度、当前环境光色温或当前环境光色度值，也可以是三者的任意两者的组合，还可以是三者的组合。其中当前环境光亮度的取值范围可以为0nit～100000nit；当前环境光色温的取值可以为1000K～10000K；当前环境光色度值可以按照如图2所示的马蹄形色度图进行色度区域划分，不同的色度区域可以对应不同的刷新频率。
可以理解的是，光环境参数(当前环境光亮度、当前环境光色温和当前环境光色度值中的至少一项)与刷新频率的预设对应关系可以根据实际需求预先设定并存储至电子设备，其对应关系的具体数值，此处不作具体限定。还可以理解的是，在检测到电子设备所处的环境发生改变时，可以重新获取电子设备所处环境的当前光环境参数，并基于新的当前光环境参数重新调整显示屏的刷新频率。
本实施例中，通过在识别电子设备所处环境的光环境参数，来判断周边环境光对用户人眼的刺激，从而推断出显示屏对用户人眼的影响，并可以根据不同的光环境参数应用不同的目标刷新频率，从而实现降低视觉疲劳和节约电子设备功耗的平衡。
在一些实施例中，电子设备所处环境的当前光环境参数包括当前环境光亮度、当前环境光色温和当前环境光色度值中的至少一项。
在本实施例中，若当前光环境参数为当前环境光亮度，当前环境光亮度越高，则可以说明当前环境对人眼的刺激越大，反而使得显示屏对人眼的影响降低，则此时显示屏可以应用较低的刷新频率；反之，当前环境光亮度越低，则可以说明当前环境对人眼的刺激越小，反而使得显示屏对人眼的影响增加，则此时显示屏可以应用较高的刷新频率。
若当前光环境参数为当前环境光色温，当前环境光色温越高，则可以说明当前环境为冷色调，对人眼的刺激越大，反而使得显示屏对人眼的影响降低，则此时显示屏可以应用较低的刷新频率；反之，当前环境光色温越低，则可以说明当前环境为暖色调，对人眼的刺激越小，反而使得显示屏对人眼的影响增加，则此时显示屏可以应用较高的刷新频率。
若当前光环境参数为当前环境光色度值，色度值通常是用色坐标(x，y)来表示的一个二维坐标，则如图2所示，可以根据马蹄形色度图进行色度区域划分(如色度区域A、色度区域B、色度区域C和色度区域D)。可以按照当前环境光色度值匹配的目标色度区域，再根据色度区域与刷新频率的预设对应关系，确定所述目标色度区域相匹配的目标刷新频率，并将该目标刷新频率用于显示屏。可以理解的是，在图2中，色度区域A至色度区域D的环境光逐渐变暖，故色度区域A至色度区域D对应的刷新频率逐渐提高。
还可以理解的是，当前光环境参数还可以包括当前环境光亮度、当前环境光色温和当前环境光色度值中的任意组合，此次不作具体限定。
本实施例中，可以通过考虑当前环境光亮度、当前环境光色温和当前环境光色度值来判断当前环境光对用户人眼的刺激，从而确定显示屏对用户人眼的影响大小，进而可以确定出更准确目标刷新频率，进一步保证了调整显示屏的刷新频率的准确性。
在一些实施例中，在视觉影响因素包括屏幕像素的亮度值和电子设备所处环境的当前光环境参数的情况下，上述步骤102可以包括如下步骤：
根据屏幕像素的亮度值，确定显示屏对应的平均亮度值；
根据平均亮度值和当前光环境参数，将显示屏的刷新频率调整为与平均亮度值和当前光环境参数相匹配的目标刷新频率。
在本实施例中，视觉影响因素可以包括屏幕像素的亮度值和电子设备所处环境的当前光环境参数。可以根据屏幕像素的亮度值，确定显示屏对应的平均亮度值。示例地，可以将显示屏所显示的内容作为一张图像，屏幕像素的亮度即可以为作为该图像的图像像素的亮度，计算显示屏对应的平均亮度值，可以是对该图像进行灰度处理，获取每个图像像素的灰阶值，再计算所有图像像素的灰阶值之和与所有图像像素数量的比值，得到该图像的平均灰阶，该平均灰阶可以确定显示屏对应的平均亮度值。以8bit的显示屏为例，平均亮度值的取值可以为0～255。
可以通过电子设备中的环境光感知模块探测并记录电子设备周边的当前光环境参数，然后可以根据平均亮度值和当前光环境参数，将显示屏的刷新频率调整为与平均亮度值和当前光环境参数相匹配的目标刷新频率。
例如，可以在平均亮度值较暗，且当前光环境参数指示当前环境光对用户人眼的刺激越大的情况下，对显示屏应用第一目标刷新频率；可以在平均亮度值较亮，且当前光环境参数指示当前环境光对用户人眼的刺激越小的情况下，对显示屏应用第二目标刷新频率；可以在平均亮度值较亮，且当前光环境参数指示当前环境光对用户人眼的刺激越大的情况下，或者在平均亮度值较暗，且当前光环境参数指示当前环境光对用户人眼的刺激越小的情况下，对显示屏应用第三目标刷新频率。其中，第一目标刷新频率、第二目标刷新频率和第三目标刷新频率满足以下条件：第一目标刷新频率＜第三目标刷新频率＜第二目标刷新频率。
可以理解的是，上述举例仅作为一个具体示例用于说明本实施例的一种实现方式，便于理解本实施例的技术方案，不作为本实施例的实现方式的具体限定。例如，还可以根据平均亮度值的取值范围，以及当前光环境 参数(当前环境光亮度、当前环境光色温和当前环境光色度值中的至少一项)的取值或区域范围，来共同匹配目标刷新频率。又例如，可以根据平均亮度值对应的权重与当前光环境参数对应的权重之和，确定刷新频率对应的目标权重因子，进而可以根据目标权重因子，以及权重因子与刷新频率的预设对应关系，确定与目标权重因子匹配的目标刷新频率，并应用于显示屏。
本实施例中，可以通过不同的屏幕像素的亮度值和电子设备所处环境的光环境参数的组合来共同调整显示屏的刷新频率，进一步保证目标刷新频率的准确性，从而实现降低视觉疲劳和节约电子设备功耗的平衡。
在一些实施例中，在视觉影响因素包括用户特征信息的情况下，上述步骤101还可以包括如下步骤：
获取目标用户的人脸图像；
根据人脸图像确定目标用户的目标用户特征信息；
上述步骤102可以包括如下步骤：
确定与目标用户特征信息相匹配的目标刷新频率；
将显示屏的刷新频率调整为目标刷新频率。
在本实施例中，视觉影响因素还可以包括用户特征信息。可以获取目标用户的人脸图像，其中目标用户可以是指正在使用该电子设备的用户。获取到人脸图像后，可以通过识别，确定目标用户的目标用户特征信息。其中，目标用户特征信息可以包括目标用户的年龄和/或目标用户使用电子设备的目标频率。确定目标用户的年龄可以是直接获取目标用户存储至电子设备中的身份信息以确定目标用户的年龄，或者可以是基于大数据进行人脸识别以推断出目标用户的年龄。确定目标用户使用电子设备的目标频率，则可以是获取一段时间内目标用户每天使用电子设备的时长，进而可以根据平均时长计算出目标频率。
可以根据目标用户特征信息匹配对应的目标刷新频率，例如，目标用户的年龄越小，则对应的目标刷新频率越高，反之，目标用户的年龄越大，则对应的目标刷新频率越低。又例如，目标用户使用电子设备的目标频率越高，则对应的目标刷新频率越高，反之，目标用户使用电子设备的目标频率越低，则对应的目标刷新频率也越低。
本实施例中，可以通过用户特征信息来调整显示屏的刷新频率，不同用户特征信息对应的用户群体应用不同的目标刷新频率，从而实现降低视觉疲劳和节约电子设备功耗的平衡。
在一些实施例中，在视觉影响因素包括应用程序类型的情况下，上述步骤101还可以包括如下步骤：
识别显示屏的当前显示界面对应的目标应用；
从多个预设的应用程序类型中确定出目标应用对应的目标应用程序类型；
上述步骤102可以包括如下步骤：
确定与目标应用程序类型相匹配的目标刷新频率；
将显示屏的刷新频率调整为目标刷新频率。
在本实施例中，视觉影响因素还可以包括应用程序类型。可以识别显示屏的当前显示界面对应的目标应用，并从多个预设的应用程序类型中确定出目标应用对应的目标应用程序类型。
可以理解的是，不同类型的应用程序其功能不同，用户使用这些应用程序时对应的使用时长也会有所区别。例如视频播放类型的应用程序、阅读类型的应用程序，用户在使用这些应用程序时通常需要花费较多的时间，换而言之，当目标应用的目标应用程序类型确定为视频播放类型或阅读类型时，通常可以说明用户需要长时间观看显示屏。又例如，通讯类型的应用程序(拨号、短信)、***通用类型的应用程序(时钟、日历)，用户在使用这些应用程序时通常仅需要花费较短的时间即可满足需求，换 而言之，当目标应用的目标应用程序类型确定为通讯类型或***通用类型时，则可以说明用户短时间观看显示屏即可。
基于不同类型的应用程序所对应的用户观看显示屏的时长不同，可以根据目标应用程序类型匹配对应的目标刷新频率，例如，目标应用程序类型确定为视频播放类型或阅读类型时，则对应的目标刷新频率越高，反之，目标应用的目标应用程序类型确定为通讯类型或***通用类型时，则对应的目标刷新频率越低。
本实施例中，可以通过应用程序类型来调整显示屏的刷新频率，不同应用程序类型对应的显示界面应用不同的目标刷新频率，从而实现降低视觉疲劳和节约电子设备功耗的平衡。
