The invention relates to a magnetic drive deformation device, particularly to a mechanism for three-dimensional dynamic or static display of two-dimensional information by using a magnetic drive deformation device. A magnetic drive unit provided by the invention is characterized by comprising an electromagnetic coil, an outer frame and an inner frame, wherein the electromagnetic coil is arranged in the outside frame and wound on the outer side of the inner frame; the upper side and the lower side of the inner frame are provided with an elastic membrane; a rigid module is attached to the elastic membrane; and permanent magnets in different directions are arranged in the cavity formed by the inner frame and the elastic membrane. The upper or lower side of the inner frame can be provided with an elastic membrane, and the other side can be fixed with a rigid baffle. The mechanism and an array thereof can be used for three-dimensional display of computer-digitized graphical information, signs and the like, and can be also used in the fields of motion control, drive actuation, remote transmission of movements and tactile sense, information transmission and the like.
