在本申请中，局部背光调节是指通过调节背光灯的亮度来调整画面的显示，由于显示面板的背光板是由数百个LED组成，背光LED可根据图像的明暗进行调节，显示屏幕中图像高亮的部分对应的背光灯的亮度达到最大，黑暗部分对应的背光灯的亮度可调节到最小，这种通过调节背光灯的亮度进而来调节画面显示的方法在提高画面显示效果的同时，减少了显示屏幕的功耗。
在本申请中，背光灯的最大亮度设定值，背光灯对应的最小电流设定值、最大电流设定值、最大过驱电流设定值等都是与显示屏幕的显示性能相关的设定值。
在本申请中，目标背光数据为用户期望显示屏幕达到的显示效果所对应的背光数据。
请参阅图1，图1为本申请实施例所提供的画面调节系统的场景示意图，仅以画面调节装置集成在电子设备中为例，首先电子设备11获取背光灯对应的最大电流设定值和期望电流值，再根据最大电流设定值以及期望电流值，确定背光灯的工作电流值，根据工作电流值、最大过驱电流设定值以及当前亮度数组，确定背光灯的目标亮度数组，最后，对电子设备11根据目标亮度数值控制背光灯的亮度，以调节屏幕10的画面显示。由于本申请提供的画面调节方法根据最大电流设定值以及期望电流值的大小关系来确定工作电流值，避免背光灯长时间工作在过高的电流下，导致硬件被损坏，提高了屏幕的寿命。
需要说明的是，图1所示的画面调节系统的场景示意图仅仅是一个示例，本申请实施例描述的电子设备、屏幕是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统的演变和新业务局景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参阅图2，图2为本申请实施例提供的画面调节方法的第一种流程示意图，用于上述电子设备，包括：
步骤201：获取背光灯对应的最大电流设定值和期望电流值。
在本申请中，背光灯对应的最大电流设定值为显示面板中与背光灯的性能相关的设定值，在此可认为是一固定值，期望电流值是用户期望显示屏幕达到的显示效果对应的电流值，其中，期望电流值可以是其他方式计算得到的，电子设备可以直接获取计算好的期望电流值，也可以是电子设备通过计算得到的，期望电流值的具体获取方式在此不做限定。
在一种实施例中，获取背光灯对应的期望电流值的步骤，包括：获取屏幕的目标背光数据以及当前显示画面的显示数据，显示数据包括背光灯的最大亮度设定值、背光灯对应的最小电流设定值以及当前显示画面对应的背光灯的当前亮度数组，当前亮度数组包括多个当前亮度数据；根据背光灯的当前亮度数组，得到当前显示画面对应的背光灯的平均亮度值；根据最小电流设定值、目标背光数据、最大亮度设定值，以及平均亮度值，得到背光灯对应的期望电流值。
屏幕的目标背光数据可以是用户在显示屏幕中输入的期望的背光数据，也可以是显示屏幕原始设定的背光数据，具体目标背光数据在此不做限定，其中，用户可以通过拖动屏幕中的亮度调节条，来确定期望的目标背光数据，也可以直接从输入框输入期望的目标背光数据，具体输入目标背光数据方法在此不做限定。
显示数据包括背光灯的最大亮度设定值、背光灯对应的最小电流设定值、最大电流设定值、最大过驱电流设定值，以及当前显示画面对应的背光灯的当前亮度数组，当前亮度数组包括多个当前亮度数据。其中，背光灯的最大亮度设定值、背光灯对应的最小电流设定值、最大电流设定值，以及最大过驱电流设定值都为显示屏幕中设定好的原始数据，该原始数据的确定与显示屏幕的性能有关，在此可以认为是原始的固定值。当前显示画面对应的背光灯的当前亮度数组与当前显示画面有关，当前显示画面不同所对应的背光灯的亮度数据不同。
步骤202：根据最大电流设定值以及期望电流值，确定背光灯对应的工作电流值。
由于最大电流设定值与显示屏幕的性能有关，在通常情况下，通入背光灯的电流值的最大值为最大电流设定值，在最大电流值设定值之内的电流值可以使屏幕的显示性能达到更好，因此，需要将期望电流值与中最大电流设定值进行比较，超过最大电流设定值的期望电流成为过驱动电流，简称过驱电流。正常情况下，期望电流可以大于最大电流设定值，但是不能最大过驱电流设定值。最大过驱电流设定值是显示屏幕的各硬件能正常运行的最大电流值，超过最大驱动电流设定值，显示屏幕的硬件会有损坏的风险，因此，需要根据最大电流设定值以及期望电流值，确定背光灯实际的允许通入的工作电流值。
如图3所示为本申请实施例提供的画面调节方法的第二种流程示意图，步骤202还包括以下几个步骤：
2031：若期望电流值小于或等于最大电流设定值，则将期望电流值确定为背光灯对应的工作电流值。
由于期望电流值小于或者等于最大电流值，显示屏幕的硬件不会因电流过大而损坏，因此，则将期望电流值确定为背光灯对应的工作电流值。
2032：若期望电流值大于背光灯对应的最大电流值，则获取背光灯对应的电流值持续大于最大电流设定值对应的过驱时间。
若期望电流值大于背光灯对应的最大电流设定值，由于在实际情况中，工作电流值可以大于最大电流设定值，但是要小于最大驱动电流设定值，且大于最大电流设定值得时间不能超过第一预设时间阈值，即为保护显示屏幕中的硬件，显示屏幕中的背光灯不能长时间工作在过高的电流下，因此设定一个第一预设时间阈值来保护显示屏幕中的硬件。
步骤2033：根据过驱时间，确定背光灯对应的工作电流值。
在一种实施例中，根据过驱时间，确定背光灯对应的工作电流值的步骤，包括：若过驱时间等于第一预设时间阈值，则将最大电流设定值确定为背光灯的工作电流值；若过驱时间大于第一预设时间阈值，则获取第二预设时间阈值，第二预设时间阈值大于第一预设时间阈值；根据第二预设时间阈值，确定背光灯对应的工作电流值；若过驱时间小于第一预设时间阈值，则获取预设时间段内，背光灯对应的电流值大于最大电流设定值对应的过驱次数；根据过驱次数，确定背光灯对应的工作电流值。
若过驱时间等于第一预设时间阈值，则说明背光灯对应的电流不能再继续增大了，因此，只能将最大电流设定值确定为背光对应的工作电流，若过驱时间小于第一预设时间阈值，还要保证背光灯没有频繁进入过驱，即若过驱次数大于或等于预设过驱次数，则将背光灯对应的最大电流设定值确定为背光灯对应的工作电流值，若过驱次数小于预设过驱次数，则将背光灯对应的最大过驱电流设定值确定为背光灯对应的工作电流值。
背光灯对应的电流可以继续增大，但是背光灯对应的电流对应的过驱时间等于第一预设时间阈值之后，背光灯对应的电流就需要减小到最大电流设定值，并持续一段时间，以保证显示屏幕对应的硬件及时散热，当电流减小一段时间后，背光灯的电流可以允许继续增大到最大驱动电流设定值，即：若过驱时间大于或等于第二预设时间阈值，则将最大过驱电流设定值确定为背光灯对应的工作电流值，若过驱时间小于第二预设时间阈值，则将最大电流设定值确定为背光灯的工作电流值，其中，第二预设时间阈值等于第一预设时间阈值加上散热时间。
步骤203：根据工作电流值、背光灯对应的最大过驱电流设定值，以及屏幕中当前显示画面对应的背光灯的当前亮度数组，确定背光灯的目标亮度数组。
在一种实施例中，根据工作电流值、背光灯对应的最大过驱电流设定值，以及屏幕中当前显示画面对应的背光灯的当前亮度数组，确定背光灯的目标亮度数组的步骤，包括：根据工作电流值以及最大过驱电流设定值，确定目标比例系数；根据目标比例系数以及当前亮度数组，确定背光灯的目标亮度数组。
以下内容为例对步骤203进行说明，首先根据工作电流值以及最大过驱电流设定值，确定目标比例系数，即：比例系数k=工作电流值/最大过驱电流设定值，再根据目标比例系数以及当前亮度数组，确定背光灯的目标亮度数组，目标亮度数组=k*当前亮度数组。
步骤204：根据目标亮度数组中的多个目标亮度数据控制背光灯的亮度，以调节屏幕的画面显示。
电子设备根据目标亮度数据中多个目标亮度数据控制背光灯的亮度，进而调节屏幕的画面显示，其中，目标亮度数组中的目标亮度数据与背光板中各背光灯一一对应。
本申请实施例提供了一种画面调节方法，该方法首先获取背光灯对应的最大电流设定值和期望电流值，再根据最大电流设定值以及期望电流值，确定背光灯对应的工作电流值，根据工作电流值、背光灯对应的最大过驱电流设定值，以及屏幕中当前显示画面对应的背光灯的当前亮度数组，确定背光灯的目标亮度数组，最后根据目标亮度数组中的多个目标亮度数组控制背光灯的亮度，以调节屏幕的画面显示，由于本申请提供的画面调节方法根据最大电流设定值以及期望电流值的大小关系来确定工作电流值，避免背光灯长时间工作在过高的电流下，导致硬件被损坏，提高了屏幕的显示寿命。
