s1: a plurality of display modules are arranged on the box body;
S2: identifying one display module as a reference display module, the other display module as an adjustment display module, wherein the adjustment display module is adjacent to the reference display module, the main control system controls a plurality of adjustable connecting pieces corresponding to the bottom of the adjustment display module, firstly, the adjustment display module is ejected out, the whole adjustment display module is higher than the reference display module, the image acquisition assembly identifies the height difference between the adjustment display module and the reference display module, and then the main control system controls the adjustable connecting pieces to downwards move the adjustment display module, so that the heights of the adjustment display module and the reference display module are consistent;
s3: and S2, sequentially adjusting the heights of all the display modules on the box body, so that the flatness of the light emitting surface of the display screen is consistent.
6. The method of claim 5, wherein at least four adjustable connectors are correspondingly connected to a single display module, and the four adjustable connectors are located at four corners of the bottom of the display module.
7. The method of claim 6, wherein in step S2, "moving the adjustment display module downward to make the adjustment display module highly consistent with the reference display module", specifically, adjusting two adjustable connectors relatively close to the reference display module to align one side of the adjustment display module close to the reference display module with the reference display module; and adjusting two adjustable connectors relatively far away from the reference display module, so that one side of the adjustment display module far away from the reference display module is aligned with the reference display module.
8. The method for intelligently adjusting the flatness of a display screen according to claim 6, wherein in step S2, "the adjustment display module is moved downward to make the adjustment display module and the reference display module have the same height", specifically, four adjustable connectors together drive the adjustment display module to move downward by a first distance, where the first distance is less than or equal to a minimum height difference value of the height differences; adjusting two of said adjustable connectors relatively adjacent said reference display module such that a side of said adjustable display module adjacent said reference display module is aligned with said reference display module; and adjusting two adjustable connectors relatively far away from the reference display module, so that one side of the adjustment display module far away from the reference display module is aligned with the reference display module.
9. The method of any one of claims 5-8, wherein in S2 and S3, the adjustment display module is in an energized state.
