请参阅图2，图2为本申请实施例提供的显示屏的背光处理方法的流程示意图，该流程可以包括：
在步骤101中，获取待显示图像。
其中，待显示图像为需要通过显示屏进行显示的图像。例如，待显示图像也可以为某视频中的其中一帧图像。
在步骤102中，当待显示图像满足预设条件时，根据待显示图像，将背光模组的多个背光区域划分为第一类背光区域和第二类背光区域。
在本实施例中，当获取到待显示图像之后，可判断待显示图像是否满足预设条件。当待显示图像满足预设条件时，可根据待显示图像，将背光模组的多个背光区域划分为第一类背光区域和第二类背光区域。其中，第一类背光区域可包括至少一个背光区域，第二类背光区域也可包括至少一个背光区域。第一类背光区域和第二背光区域的总数量与背光模组的多个背光区域的数量相同。
在步骤103中，控制第一类背光区域的亮度值为根据待显示图像确定的目标亮度值。
例如，假设第一类背光区域有5个，则可控制5个第一类背光区域的亮度值为根据待显示图像确定的目标亮度值。
在步骤104中，控制第二类背光区域的亮度值为预设亮度值，预设亮度值小于目标亮度值，预设亮度值与目标亮度值的差值大于预设差值。其中，预设亮度值可根据实际情况设置，此处不作具体限制。

本实施例中，当控制第一类背光区域的亮度值为根据待显示图像确定的目标亮度值，并控制第二类背光区域的亮度值为预设亮度值之后，可基于该第一类背光区域和第二类背光区域的亮度控制显示面板显示待显示图像，从而使得待显示图像的对比度相对较高。
本申请实施例中，获取待显示图像；当待显示图像满足预设条件时，将背光模组的多个背光区域划分为第一类背光区域和第二类背光区域；控制第一类背光区域的亮度值为根据待显示图像确定的目标亮度值；控制第二类背光区域的亮度值为预设亮度值，目标亮度值大于预设亮度值，预设亮度值与目标亮度值的差值大于预设差值；基于调节后的第一类背光区域和第二类背光区域控制显示面板显示待显示图像，以此，通过使得第一类背光区域的亮度值和第二类背光区域的亮度值差距较大，使得最终显示出的待显示图像的对比度较高。
在一可选的实施例中，该显示屏的背光处理方法还可以包括：
当待显示图像为相应视频中的第n帧图像或第n帧图像之后的图像时，根据待显示图像，确定每个背光区域对应的目标亮度值和均值；
统计目标亮度值不等于0的背光区域的目标数量；
当目标数量大于预设数量，且每个背光区域对应的均值小于预设均值时，确定待显示图像满足预设要求；
当待显示图像的前n-1帧图像均满足预设要求时，确定待显示图像满足预设条件。
其中，n可为大于1的正整数。
比如，当获取到待显示图像之后，可先判断该待显示图像是否为相应视频中的第n帧图像或第n帧图像之后的图像。具体的，可通过比较待显示图像与其前一帧图像的相似度来判断该待显示图像是否为相应视频中的一帧图像；其中，当待显示图像与其前一帧图像的相似度大于预设相似度时，可判定该待显示图像为相应视频中的一帧图像；当待显示图像与其前一帧图像的相似度大于预设相似度时，可判定该待显示图像不为相应视频中的一帧图像。其中，预设相似度可根据实际情况设置，此处不作具体限制。
当待显示图像为相应视频中的一帧图像时，可继续通过比较待显示图像的前n-1帧图像中相邻图像的相似度来确定该待显示图像是否为相应视频中的第n帧图像。以此类推，也可继续通过比较第n帧图像之后的图像之前的图像中相邻图像的相似度来确定该待显示图像是否为相应视频中的第n帧图像之后的图像。其中，相应视频可以为任意视频。
当待显示图像为相应视频中的第n帧图像或第n帧图像之后的图像时，可根据该待显示图像，确定每个背光区域对应的目标亮度值和每个背光区域对应的均值。
随后，可统计目标亮度值不等于0的背光区域的目标数量。例如，当目标亮度值不等于0的背光区域有5个时，则可确定目标数量为5。
接着，可判断目标数量是否大于预设数量。其中，预设数量可根据实际情况设置，此处不作具体限制。例如，若目标数量为5，预设数量为4，则可判断目标数量大于预设数量。
还可判断每个背光区域对应的均值是否小于预设均值。其中，预设均值可根据实际情况设置，此处不作具体限制。例如，当某个背光区域对应的均值为112，预设均值为150，则可确定该背光区域对应的均值小于预设均值。
当目标数量大于预设数量，且每个背光区域对应的均值小于预设均值时，可确定待显示图像满足预设要求。还可按照与上述过程相同的过程，确定待显示图像的前n-1帧图像是否均满足预设要求。例如，对于待显示图像的前n-1帧图像中的任意图像，可根据该图像，确定每个背光区域对应的亮度值和均值。然后，统计亮度值不等于0的背光区域的数量，当该数量大于预设数量，且每个背光区域对应的均值小于预设均值时，确定该图像满足预设要求。当待显示图像的前n-1帧图像也均满足预设要求时，可确定待显示图像满足预设条件。
而当待显示图像满足：为相应视频中的第n-1帧或第n-1帧之前的图像、目标数量小于或等于预设数量、多个背光区域中存在至少一个背光区域对应的均值大于或等于预设均值和待显示图像的前n-1帧图像中存在至少一帧图像不满足预设要求中的任一条件时，可确定待显示图像不满足预设条件。当待显示图像不满足预设条件时，可按照相关技术中的显示方式显示该待显示图像。

比如，首先，将待显示图像划分为与多个背光区域对应的多个图像区域。例如，假设背光区域有12个，则图像区域也有12个，其中，一背光区域与一图像区域对应。另外，由于背光模组和显示面板层叠设置，待显示图像通过显示面板显示，当待显示图像的某个图像区域显示在显示面板的左上角时，与该图像区域对应的背光区域也在背光模组的左上角。
随后，可确定每个图像区域的每个像素点的灰度值，得到每个图像区域对应的多个灰度值。例如，假设某个图像区域有100个像素点，则该图像区域对应的灰度值有100个。
接着，可确定每个图像区域对应的多个灰度值的均值，得到每个图像区域对应的均值。例如，假设某图像区域对应的多个灰度值分别为152、154、155、160、161，则该图像区域对应的均值为156.4。

接着，可确定每个图像区域对应的多个灰度值的均值，得到每个图像区域对应的均值。例如，假设某图像区域对应的多个灰度值分别为152、154、155、160、161，则该图像区域对应的均值为156.4。
可确定每个图像区域对应的多个灰度值的最大值，得到每个图像区域对应的最大值。例如，假设某图像区域对应的多个灰度值分别为152、154、155、160、161，则该图像区域对应的最大值为161。

之后，可计算每个图像区域对应的均值与其对应的权重值的乘积、每个图像区域对应的最大值与其对应的权重值的乘积，以及待显示图像对应的均值与其对应的权重值的乘积，得到每个背光区域对应的第一乘积、第二乘积和第三乘积。其中，某个背光区域对应的第一乘积、第二乘积和第三乘积分别为该背光区域对应的图像区域对应的均值与其对应的权重值的乘积、该背光区域对应的图像区域对应的最大值与其对应的权重值的乘积，以及待显示图像对应的均值与其对应的权重值的乘积。

需要说明的是，具体如何根据待显示图像，确定每个背光区域对应的目标亮度值可参见前面的实施例，此处不再赘述。
在一可选实施例中，在控制第一类背光区域的亮度值为根据待显示图像确定的目标亮度值时，可将待显示图像划分为与多个背光区域对应的多个图像区域；然后，可从多个图像区域中确定出与第一类背光区域对应的图像区域，得到目标图像区域；可确定目标图像区域的每个像素点的灰度值，得到目标图像区域对应的多个灰度值；可确定待显示图像中的每个像素点的灰度值，得到待显示图像对应的多个灰度值；确定目标图像区域对应的多个灰度值的均值，得到目标图像区域对应的均值；确定目标图像区域对应的多个灰度值的最大值，得到目标图像区域对应的最大值；确定待显示图像对应的多个灰度值的均值，得到待显示图像对应的均值；根据目标图像区域对应的均值、目标图像区域对应的最大值和待显示图像对应的均值，确定第一类背光区域对应的目标亮度值；当确定出第一类背光区域对应的目标亮度值之后，可控制第一类背光区域的亮度值为该目标亮度值。
