检测是否发生闪屏；
若发生闪屏，则获取显示屏的液晶分子偏转的参考电压VCOM电压值；
计算获取的VCOM电压值与预设的VCOM电压值的差值；

判断获取的VCOM电压值是否在预设电压范围值之内；
若所获取的VCOM电压值在预设电压范围值之内，则确定发生闪屏。
一实施例中，检测是否发生闪屏，包括：
向所述显示屏发送灰阶图像和闪烁度测试图片，以获取所述显示屏的闪烁度值；
判断获取的闪烁度值是否在预设闪烁度范围值之内；
若所获取的闪烁度值在预设闪烁度范围值之内，则确定发生闪屏。
一实施例中，检测是否发生闪屏，包括：
向所述显示屏发送检测指令，以获取所述显示屏的VCOM电压值，以及向所述显示屏发送灰阶图像和闪烁度测试图片，以获取所述显示屏的闪烁度值；
判断获取的VCOM电压值是否在预设电压范围值之内，以及判断获取的闪烁度值是否在预设闪烁度范围值之内；
若所获取的VCOM电压值在预设电压范围值之内，且所获取的闪烁度值在预设闪烁度范围值之内，则确定发生闪屏。
一实施例中，根据所述获取的VCOM电压值、所述预设的VCOM电压值及所述差值计算目标VCOM电压值，包括：
计算所述获取的VCOM电压值与所述预设的VCOM电压值的平均值；
将所述平均值加上所述差值得到第一目标VCOM电压值，以及将所述平均值减去所述差值得到第二目标VCOM电压值；
取所述第一目标VCOM电压值与所述第二目标VCOM电压值中，最靠近所述预设的VCOM电压值的电压值，作为所述目标VCOM电压值。

根据所述获取的VCOM电压值以及所述目标VCOM电压值确定调整步长。

根据所述调整步长调整所述显示屏的寄存器值，以将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。
本发明实施例提供的闪屏处理方法的一个具体应用场景，可如图1a所示，电子设备可以检测是否发生闪屏，若发生闪屏，则获取显示屏的液晶分子偏转的参考电压VCOM电压值；计算获取的VCOM电压值与预设的VCOM电压值的差值；根据所述获取的VCOM电压值、所述预设的VCOM电压值及所述差值计算目标VCOM电压值；将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。调整之后，例如图1a所示，闪屏现象消失，显示屏上显示内容正常。
在一优选实施例中，提供了一种闪屏处理方法，如图1b所示，包括如下步骤：
步骤101、检测是否发生闪屏；
通过实践和研究发现，VCOM电压（液晶分子偏转的参考电压）对液晶显示有直接影响，修改VCOM电压值会明显改善或者恶化显示屏的闪屏现象，因而，本实施例中，可以通过检测显示屏的VCOM电压值来判断是否发生闪屏。
闪烁度（flicker）是一项测试显示屏闪烁的硬件指标，本实施例中，还可以通过检测显示屏的闪烁度值来判断是否发生闪屏。当然，实际应用中，还可以将显示屏的VCOM电压值与闪烁度值结合起来判断是否发生闪屏，以提高闪屏检测准确度。
步骤102、若发生闪屏，则获取显示屏的VCOM电压值；
导致闪屏的原因有很多，例如硬件故障，背光出现问题，静电累积干扰，显示屏液晶内部电荷不稳，显示屏液晶老化等，本实施例主要检测并解决显示屏液晶内部电荷不稳、显示屏液晶老化导致的闪屏。
VCOM电压值是保存在显示屏硬件电路的寄存器中的，因此可以通过向显示屏发送检测指令，使显示屏读取寄存器中的值并返回，然后根据显示屏返回的数据获取显示屏的VCOM电压值。
步骤103、计算获取的VCOM电压值与预设的VCOM电压值的差值；
预设的VCOM电压值可以是根据理论或实践得出的，显示效果较佳或最佳状态下的VCOM电压值。
步骤104、根据所述获取的VCOM电压值、所述预设的VCOM电压值及所述差值计算目标VCOM电压值；
具体地，可以先计算所述获取的VCOM电压值与所述预设的VCOM电压值的平均值，将所述平均值加上上述差值得到第一目标VCOM电压值，以及将所述平均值减去上述差值得到第二目标VCOM电压值，取所述第一目标VCOM电压值与所述第二目标VCOM电压值中，最靠近所述预设的VCOM电压值的电压值，作为所述目标VCOM电压值。
例如，所获取的VCOM电压值为96，预设的VCOM电压值为100，则二者的差值为4，平均值为98，第一目标VCOM电压值为98+4即102，第二目标VCOM电压值为98-4即94，第一目标VCOM电压值与预设的VCOM电压值的差值为2，第二目标VCOM电压值与预设的VCOM电压值的差值为6，很明显，第一目标VCOM电压值102更靠近预设的VCOM电压值100，则将第一目标VCOM电压值102作为目标VCOM电压值。
步骤105、将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。
由于VCOM电压值是保存在显示屏硬件电路的寄存器中的，因此可以通过调整所述显示屏的寄存器值将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。
本实施例中，会自动检测是否发生闪屏，若检测到发生闪屏，则自动根据显示屏的VCOM电压值与预设的VCOM电压值计算得到目标VCOM电压值，直接将显示屏的VCOM电压值调整为所述目标VCOM电压值，以消除闪屏现象，从而改善了用户体验，提高了产品的品质。
上述实施例所描述的方法，本实施例将做进一步的描述，如图2所示，本实施例的方法包括以下步骤：
步骤201、向显示屏发送检测指令；
步骤202、获取所述显示屏的VCOM电压值；
VCOM电压值是保存在显示屏硬件电路的寄存器中的，因此可以通过向显示屏发送检测指令，使显示屏读取寄存器中的值并返回，然后根据显示屏返回的数据获取显示屏的VCOM电压值。
步骤203、判断获取的VCOM电压值是否在预设电压范围值之内，若在，则执行步骤207，否则，执行步骤212结束处理；
具体实现中，可预设VCOM电压值，取预设的VCOM电压值正负预设数值（例如3%、5%等）内的电压值为预设电压范围值，预设的VCOM电压值可以是根据理论或实践得出的，显示效果较佳或最佳状态下的VCOM电压值。例如预设的VCOM电压值为100，预设电压范围值可以为 以及 （即正负3%），或者预设电压范围值为 以及 （即正负5%）等。上面的例子中，若获取的VCOM电压值为98，则在所述预设电压范围值之内；若获取的VCOM电压值为92，则不在所述预设电压范围值之内，若不在所述预设电压范围值之内，则暂不做处理，即结束处理。
步骤204、向显示屏发送灰阶图像和闪烁度测试图片；
步骤205、获取所述显示屏的闪烁度值；
向显示屏发送灰阶图像和闪烁度测试图片之后，显示屏会进行显示，之后显示屏会反馈寄存器的常规电压值，这些常规电压值包括vgl和vgh（像素点上开关管的开启、关闭电压），vsn和vsp（正、负液晶驱动电源电压）等，判断这些常规电压值与对应的预设电压值（该预设电压值为显示屏显示灰阶图像和闪烁度测试图片后的理论电压值）是否相同，若相同（可能未出现闪屏），则结束处理，若不同，则根据预存的对应关系（即电压值与闪烁度值的对应关系）获取这些常规电压值对应的闪烁度值，判断获取的闪烁度值是否在预设闪烁度范围值之内。预设闪烁度范围值可以通过预设闪烁度值，取预设的闪烁度正负预设数值（例如3%、5%等）范围内的闪烁度值来获得。例如，预设的闪烁度为50，预设闪烁度范围值可以为 以及 （即正负3%），或者预设闪烁度范围值为 以及 （即正负5%）等。上面的例子中，若获取的闪烁度值为49，则在所述预设闪烁度范围值之内；若获取的VCOM电压值为42，则不在所述预设闪烁度范围值之内，若不在所述预设闪烁度范围值之内，则暂不做处理，即结束处理。
步骤206、判断获取的闪烁度值是否在预设闪烁度范围值之内，若在，则执行步骤207，否则，执行步骤212结束处理；
步骤207、确定发生闪屏；
需要说明的是，具体实现中，可仅通过显示屏的VCOM电压值来判断是否发生闪屏，即闪屏检测过程仅执行步骤201~203；也可以仅通过显示屏的闪烁度值来判断是否发生闪屏，即闪屏检测过程仅执行步骤204~206；当然也可以结合显示屏的VCOM电压值与闪烁度值来判断是否发生闪屏，即闪屏检测过程中，步骤201~203与步骤204~206同时执行，这样可以提高闪屏检测准确度。
导致闪屏的原因有很多，例如硬件故障，背光出现问题，静电累积干扰，显示屏液晶内部电荷不稳，显示屏液晶老化等，本实施例主要检测并解决显示屏液晶内部电荷不稳、显示屏液晶老化导致的闪屏。上面的步骤中，若显示屏的VCOM电压值不在预设电压范围值之内，或者显示屏的闪烁度值不在预设闪烁度范围值之内，则可能是由于硬件故障或其他原因导致的闪屏，针对这类闪屏，本实施例可以暂不做处理。
步骤208、计算所述获取的VCOM电压值与所述预设的VCOM电压值的差值，以及计算所述获取的VCOM电压值与所述预设的VCOM电压值的平均值；
步骤209、将所述平均值加上所述差值得到第一目标VCOM电压值，以及将所述平均值减去所述差值得到第二目标VCOM电压值；
步骤210、取所述第一目标VCOM电压值与所述第二目标VCOM电压值中，最靠近所述预设的VCOM电压值的电压值，作为所述目标VCOM电压值；
例如，所获取的VCOM电压值为102，预设的VCOM电压值为100，则二者的差值为2，平均值为101，第一目标VCOM电压值为101+2即103，第二目标VCOM电压值为101-2即99，第一目标VCOM电压值与预设的VCOM电压值的差值为3，第二目标VCOM电压值与预设的VCOM电压值的差值为1，很明显，第二目标VCOM电压值99更靠近预设的VCOM电压值100，则将第二目标VCOM电压值99作为目标VCOM电压值。
步骤211、根据所述获取的VCOM电压值以及所述目标VCOM电压值确定调整步长；
具体地，可以根据所述获取的VCOM电压值以及所述目标VCOM电压值的差值确定调整步长，例如，如果所述获取的VCOM电压值与所述目标VCOM电压值相差3，则可以确定调整步长为1，而如果所述获取的VCOM电压值与所述目标VCOM电压值相差0.3，则可以确定调整步长为0.1。
步骤212、根据所述调整步长调整所述显示屏的寄存器值，以将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。
由于VCOM电压值是保存在显示屏硬件电路的寄存器中的，因此可以通过根据所确定的调整步长调整所述显示屏的寄存器值，以将所述显示屏的VCOM电压值调整为所述目标VCOM电压值。
本实施例中，会自动检测是否发生闪屏，若检测到发生闪屏，则自动根据显示屏的VCOM电压值与预设的VCOM电压值计算得到目标VCOM电压值，直接将显示屏的VCOM电压值调整为所述目标VCOM电压值，以消除闪屏现象，从而改善了用户体验，提高了产品的品质。
