Abstract
The present invention relates to a rotary type display device comprising a fixed module and a rotation module, wherein the rotation module comprises: a rotating body frame; a light source module; a first sensor for sensing a rotational speed and a phase of the rotation module; and an image output control unit for controlling an image output using the light source module, by using a first sensing value obtained through the first sensor, and the fixed module comprises: a fixed body frame; a motor for rotating the rotating body frame; a second sensor for sensing the rotational speed and the phase of the rotation module; and a motor control unit for controlling at least one of the rotational speed and phase of the motor by using a second sensing value obtained through the second sensor.
