A 3D television (3D-TV) is a television set that employs techniques of 3D presentation, such as stereoscopic capture, multi-view capture, or 2D plus depth, and a 3D display�a special viewing device to project a television program into a realistic three-dimensional field.

here are several techniques to produce and display 3D moving pictures.
Common 3D display technology for projecting stereoscopic image pairs to the viewer include:

With lenses:
  • Anaglyphic 3D (with passive red-cyan lenses)
  • Polarization 3D (with passive polarized lenses)
  • Alternate-frame sequencing (with active shutter lenses)
Without lenses:
  • Autostereoscopic displays, sometimes referred to commercially as Auto 3D.
