Image display device

An image display device comprising:

• a fixed module fixed to a base, the fixed module comprising a main controller, a motor, a communication transmitter, and a power transmitter;
• and
• a rotary module rotatably connected to the motor, the rotary module comprising an optical module provided with a plurality of light sources and further comprising a communication receiver and a power receiver configured to receive a command and power from the main controller to form an illumination image by turning the plurality of light sources on or off,
• wherein the fixed module further comprises a fixed plate, wherein the motor, the communication transmitter, and the power transmitter are mounted on the fixed plate,
• wherein the rotary module further comprises a rotary plate connected to the fixed plate via the motor, wherein the optical module, the communication receiver, and the power receiver are mounted on the rotary plate,
• wherein the motor comprises a stator and a rotor, wherein the stator is mounted to a center portion of the fixed plate, and wherein the rotor is connected to a center portion of the rotary plate,
• wherein each of the fixed plate and the rotary plate comprises a communication through-hole formed in a center thereof,
• wherein each of the stator and the rotor of the motor has a hollow shape having a cavity formed therein, and
• wherein the communication transmitter and the communication receiver transmit and receive a signal therebetween through the communication through-hole formed in each of the fixed plate and the rotary plate and the cavity formed in each of the stator and the rotor.
