18. A display device for a splicing display screen comprising a plurality of display panels spliced with each other, wherein the display device for the splicing display screen comprises a gray-scale compensation module;
the gray-scale compensation module is configured to sample frames of image data in a sequence of video frames according to a preset sequence; and compensate, each time one frame of image data is sampled, a gray scale of the sampled current frame of image data to obtain compensated frame of image data; and
the gray-scale compensation module comprises a first determination unit, a filtering unit, a second determination unit, and a compensation unit, wherein
the first determination unit is configured to determine initial gray-scale compensation data according to first gray-scale data for each pixel in the current frame of image data and a pre-generated gray-scale compensation data table;
the filtering unit is configured to acquire temperature influence data of the current frame of image data; and filter each temperature influence data according to preset filter parameter information to obtain a gray-scale compensation coefficient;
the second determination unit is configured to determine target gray-scale compensation data according to the gray-scale compensation coefficient and the initial gray-scale compensation data; and
the compensation unit is configured to compensate the gray scale of the current frame of image data according to the target gray-scale compensation data to obtain the compensated frame of image data.
