Three-dimensional advertisement device

A three-dimensional advertising device comprising:

• a frame configured to have a predetermined shape;
• a plurality of unit cells arranged on the frame in a form of an X-Y matrix so as to be supported by the frame;
• and
• a controller for controlling a power supply device in response to an external input signal to selectively supply electric power to selected ones of the unit cells such that the unit cells are selectively driven, wherein
• each of the unit cells comprises:
• a cell plate having a magnet disposed at a rear surface thereof, an upper end of the cell plate being hingedly coupled to the frame such that the cell plate is disposed vertically;
• and
• an electromagnet disposed so as to be opposite the magnet of the cell plate while having a same polarity, the electromagnet being configured to turn the cell plate forwards by repulsive force when electric power is supplied to the electromagnet according to a signal from the controller.
