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:
- Neither 3-D glasses nor head-tracked devices are not required.
- 3DTV provides lateral head positioning and look-around ability. Pseudo-3D (reversed depth) is eliminated as with lenticular 3-D systems.
- 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.
- The device can be used as a computer display, for video arcade games, medical visualization, or by air traffic controllers.
- The 3DTV image can be projected to virtually any screen size.
- The 3DTV is flickerless.
The 3DTV is economical to produce because it uses a single LC panel and conventional optics.
