Abstract: A stacking screen door has two rails and multiple door panels. Each one of the rails has a groove, a conductive bar, and an elastic assembly. The conductive bar is movably located in the groove. The elastic assembly is connected to the conductive bar and the groove, and is configured to push the conductive bar out of the groove. The door panels selectively move along the two rails and are sequentially connected vertically to each other in the rail. Each one of the door panels has two electric assemblies and multiple display screens. Each one of the display screens is electrically connected to the two electric assemblies. When each one of the door panels moves along the two rails, each one of electric assemblies is respectively connected to the conductive bar. Therefore, power can be supplied to the display screens.
