Abstract
A splicing display screen includes: a gray scale compensation circuit; and display panels spliced together and each divided into display areas. The gray scale compensation circuit includes: a sampling module, configured to sample, according to a preset sequence order, frame image data in a video frame sequence to obtain current frame image data; and a processor, where 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; determine a gray scale compensation coefficient of each display area; determine target gray scale compensation data according to the gray scale compensation coefficient and the initial gray scale compensation data; and perform, according to the target gray scale compensation data, gray scale compensation on the current frame image data to obtain compensated frame image data.
