步骤S33：在所述待补偿区域的范围超过预设的补偿阈值范围时，利用所述第二待补偿区域对所述显示图像进行补偿。
举例来说，所述预设的补偿阈值范围可以是8*8。即，当确定的待补偿区域的范围超过8*8时，该补偿区域可以是第二待补偿区域，可以利用所述第二待补偿区域对所述显示图像进行补偿；而当确定的待补偿区域的范围没有超过8*8时，该补偿区域可以是第一待补偿区域，可以利用所述第一待补偿区域对所述显示图像进行补偿。即，对于不同范围大小的待补偿区域，在本申请实施例中可以采用不同的补偿方式进行补偿，从而解决利用单一补偿区域无法修复显示图像的局部细微处显示不均匀的问题，实现对于不同显示区域的精细化补偿，进而提升补偿效果，改善显示不均匀的现象。
进一步地，所述预设的补偿阈值范围可以根据所述显示器的显示图像的不同动态调整。由于对于不同的显示图像，显示不均匀的现象会有所差异，因此，可以通过动态调整所述预设的补偿阈值范围，针对不同的显示图像进行不同形式的补偿，从而提高补偿的精准度。

步骤S333：根据所述第三区域内的像素单元所对应的补偿值以及所述第四区域内的像素单元所对应的补偿值对所述显示图像进行补偿。
具体的，所述第二待补偿区域中的第三区域以及第四区域的大小可以以任意形式进行划分。由于所述第二待补偿区域比所述第一待区域大，因此第三区域以及第四区域的划分可以有更多形式。例如，第三区域也可以是类似于第一区域，包括位于所述第二待补偿区域的四个边角位置的像素点。
需要说明的是，在步骤S332中，可以利用线性插值根据所述第三区域内的像素单元所对应的补偿值确定所述第四区域内的像素单元所对应的补偿值。即，在本申请实施例中，示例性的，可以利用内插对所述第一待补偿区域进行补偿，利用线性插值对所述第二待补偿区域进行补偿。由于对所述第一待补偿区域进行补偿的补偿方式可以与对所述第一待补偿区域进行补偿的补偿方式不同，因此可以解决利用单一补偿区域无法修复显示图像的局部细微处显示不均匀的问题，实现对于不同显示区域的精细化补偿，进而提升补偿效果，改善显示不均匀的现象。可以理解，除了利用内插和线性插值进行补偿，在本申请实施例中还可以设置其他的补偿方式，本申请对于所述第一待补偿区域以及所述第二待补偿区域各自的补偿方式并不限定。
此外，本申请还提供了一种显示器，所述显示器包括：获取模块，与识别模块电连接，所述获取模块用于获取所述显示器的显示图像；识别模块，与获取模块以及补偿模块电连接，所述识别模块用于确定所述显示图像对应的待补偿区域，其中，所述待补偿区域包括至少一个第一待补偿区域以及至少一个第二待补偿区域；补偿模块，与识别模块电连接，所述补偿模块用于基于所述待补偿区域对所述显示图像进行补偿，其中，所述至少一个待补偿区域的补偿方式与所述至少一个第二待补偿区域的补偿方式不同。
进一步地，所述识别模块包括：第一识别模块，用于确定所述显示图像的至少一个第一待补偿区域；第二识别模块，用于确定所述显示图像的至少一个第二待补偿区域。
进一步地，所述第一识别模块包括：第一获取模块，用于获取各个所述第一待补偿区域的第一待补偿参数以及第二待补偿参数；第一待补偿参数设置模块，用于根据各个所述第一待补偿区域的第一待补偿参数确定该第一待补偿区域在水平方向上的长度；第二待补偿参数设置模块，用于根据各个所述第一待补偿区域的第二待补偿参数确定该第一待补偿区域在竖直方向上的长度。
进一步地，各个所述第一待补偿区域包括至少一个第一待补偿子区域，其中，所述第一识别模块还包括：第一待补偿子区域确定模块，用于确定各个所述第一待补偿区域的至少一个第一待补偿子区域。
进一步地，第一待补偿子区域确定模块具体用于：获取各个所述第一待补偿子区域的第三待补偿参数以及第四待补偿参数；根据各个所述第一待补偿子区域的第三待补偿参数确定该第一待补偿子区域在水平方向上的长度；根据各个所述第一待补偿子区域的第四待补偿参数确定该第一待补偿子区域在竖直方向上的长度。
进一步地，所述补偿模块包括：判断模块，用于判断所述待补偿区域的范围是否超过预设的补偿阈值范围；第一补偿模块，用于在所述待补偿区域的范围不超过预设的补偿阈值范围时，利用所述第一待补偿区域对所述显示图像进行补偿；第二补偿模块，用于在所述待补偿区域的范围超过预设的补偿阈值范围时，利用所述第二待补偿区域对所述显示图像进行补偿。
进一步地，所述第一待补偿子区域包括第一区域以及第二区域，各个所述区域分别包括至少一个像素单元，其中，所述第一补偿模块包括：第一区域补偿确定模块，用于确定所述第一区域内的像素单元所对应的补偿值；第二区域补偿确定模块，用于根据所述第一区域内的像素单元所对应的补偿值确定所述第二区域内的像素单元所对应的补偿值；第一补偿子模块，用于根据所述第一区域内的像素单元所对应的补偿值以及所述第二区域内的像素单元所对应的补偿值对所述显示图像进行补偿。
进一步地，所述第二区域补偿确定模块包括：第一估算模块，用于利用内插根据所述第一区域内的像素单元所对应的补偿值对所述第二区域内的像素单元所对应的补偿值进行估算，得到所述第二区域内的像素单元所对应的估算值；第一估算确定模块，用于将所述第二区域内的像素单元所对应的估算值作为所述第二区域内的像素单元所对应的补偿值。
进一步地，所述第二待补偿区域包括第三区域以及第四区域，所述第二补偿模块包括：第三区域补偿确定模块，用于确定所述第三区域内的像素单元所对应的补偿值；第四区域补偿确定模块，用于根据所述第三区域内的像素单元所对应的补偿值确定所述第四区域内的像素单元所对应的补偿值；第二补偿子模块，用于根据所述第三区域内的像素单元所对应的补偿值以及所述第四区域内的像素单元所对应的补偿值对所述显示图像进行补偿。
需要说明的是，所述显示器的各个模块用于执行本申请实施例的显示器的补偿方法。有关所述显示器的各个模块的具体细节，可参照本申请实施例中关于所述显示器的补偿方法的具体描述，不再赘述。
