The invention discloses a display screen splicing method and a display screen splicing system. The display screen splicing method is applied to a biped robot, and comprises the steps of receiving position information and reference plane information sent by a measuring device; fixing a connecting piece at a preset position of the base according to the position information; gluing the surface of thebase and forming a glue layer, specifically, the surface of the glue layer and the reference plane are located on the same plane; and fixing a display screen unit on the base with the glue layer through the connecting piece. Compared with the prior art, the display screen splicing method and the display screen splicing system solve the problem of bright lines or dark spots of display screens caused by uneven walls, and effectively guarantee the display effect of the display screens.
