Claim Text:
1. A three-dimensional (3D) display device, comprising: an optical system, including a high speed projector, configured to project light forming an image, in a predetermined direction; a rotating mirror, with axial rotation about a central axis in line with the predetermined direction, configured to reflect the light forming an image; a rotating lens, with radial rotation about the central axis, configured to invert the reflected light forming an image; a display unit provided in an upper portion or a lower portion of the optical system, wherein a side surface of the display unit includes a holographic screen; and a reflecting mirror, shaped around the first mirror and the lens, and configured to reflect the light forming an image, towards the holographic screen, wherein the reflected light is displayed via the holographic screen; and an operation control unit configured to control an operation of the optical system, wherein the projected light embodies a horizontal parallax by having a vertical scattering angle larger than a horizontal scattering angle.
