An exterior display system can be configured and arranged around a structure. The exterior display system includes a mechanical supporting structure configured and arranged about the exterior surface of the structure. This mechanical supporting structure can include various supporting structures and/or mounting structures which are configured and arranged to form a mechanical lattice framework. An electronic visual display device can be connected to the mechanical lattice framework to form the exterior display system. The electronic visual display device can include multiple electronic visual display panels which are connected to the mechanical lattice framework. Each of these multiple electronic visual display panels can include multiple groups of multiple light-emitting diodes (LEDs), also referred to electronic LED disc assemblies, that are configured and arranged in a series of one or more rows and/or a series of one or more columns.

An image display device is disclosed in which electrical connection to a rotary body is reliably maintained during rotation of the rotary body and supply of power and transmission and reception of a signal are stabilized. Since transmission and reception of a signal between a communication transmitter and a communication receiver are implemented through a cavity formed in a motor, introduction of an external signal is blocked, and thus security and control stability are ensured. Even when a rotary module rotates at a high speed, damage thereto due to friction is prevented, and thus the durability thereof is ensured. Rotation of the rotary module is stabilized through structural stabilization.
