Abstract
A picture compensation method and apparatus, a display device and a non-volatile computer-readable storage medium are disclosed. The method includes: partitioning light-emitting devices in a plurality of first partitions based on information of the plurality of first partitions of a backlight source to obtain a plurality of second partitions, wherein the first partition includes a plurality of synchronously controlled light-emitting devices, and the number of rows and the number of columns of light-emitting devices in each of the plurality of second partitions are equal; fitting a luminance diffusion curve of each of the plurality of second partitions based on a luminance diffusion curve of each light-emitting device in each of the plurality of second partitions; determining a backlight value of a pixel unit corresponding to each pixel on a display panel based on the luminance diffusion curve of each of the plurality of second partitions and a gray-scale value of each pixel of an input image; and compensating for a picture of the input image based on the backlight value of each pixel unit.
