Correction method, device, terminal equipment, system and readable storage medium

The invention is suitable for the technical field of display screens, and provides a correction method and device, terminal equipment, a system and a readable storage medium. The correction method is applied to the sub-pixel display screen, the sub-pixel display screen comprises a plurality of pixels, each pixel comprises lamp points of multiple colors, the number of lamp points of a target color in each pixel is multiple, and the target color is any one or more colors in the multiple colors. The method specifically comprises the following steps: acquiring initial optical data of each lamp point included in the sub-pixel display screen; according to the initial optical data of each lamp point, a correction coefficient of each pixel is determined, the correction coefficient of each pixel comprises a correction coefficient component of each lamp point included in the corresponding pixel, and the correction coefficient component of the lamp point of each color is used for complementing other colors except the co
