Auto-stereoscopic 3-D TV

Auto-stereoscopic 3-D TV

(3D without glasses)



      HinesLab “3-D TV”, a 3-dimensional video display that provides true stereoscopic images, without glasses.  Several viewers can move comfortably in front of the display, seeing true stereo images with motion parallax.  Applications include 3-D television, 3-D video arcade games, scientific, medical and avionic displays.


Images used in 3DTV demonstrations at HinesLab.

      The HinesLab 3DTV is built around a single liquid crystal panel, on which multiple images are arranged and projected to a rear-projection screen where they form the 3-D image. Stereo and motion parallax allow the viewer to confirm the positions and roundness of objects as the observer changes positions.


HinesLab 3DTV advantages over other stereo displays:

  1. Neither 3-D glasses nor head-tracked devices are not required.  
  2. 3DTV provides lateral head positioning and look-around ability.  Pseudo-3D (reversed depth) is eliminated as with lenticular 3-D systems.
  3. The 3DTV broadcasts are done with a single TV channel.  3DTV images are shown directly in 3D, or recorded and replayed with a single DVR.
  4. The device can be used as a computer display, for video arcade games, medical visualization, or by air traffic controllers.
  5. The 3DTV image can be projected to virtually any screen size.
  6. The 3DTV is flickerless.



      The 3DTV is economical to produce because it uses a single LC panel and conventional optics.
