1. A display apparatus, comprising a gray scale compensation apparatus for performing gray scale compensation on display data in the display apparatus, wherein the display apparatus comprises a plurality of display regions; the gray scale compensation apparatus comprises a sampling module and a processor;
the sampling module is configured to sample frame image data in a video frame sequence according to a preset sequence order, to obtain current frame image data; and
the processor is configured to: determine initial gray scale compensation data according to first gray scale data of each pixel in the current frame image data and a pre-generated gray scale compensation data table; acquire gray scale compensation information of an image data set corresponding to the current frame image data, where in the gray scale compensation information comprises gray scale compensation coefficients of the current frame image data in respective display regions, and the image data set comprises continuous multiple frames of image data sampled by the sampling module;
determine target gray scale compensation data according to the gray scale compensation coefficients of the current frame image data in the respective display regions and the initial gray scale compensation data; and perform gray scale compensation on the current frame image data according to the target gray scale compensation data, to obtain compensated frame image data.
