There’s Something about 3D TV
A 3D television that employs techniques of 3D presentation such as stereoscopic display, multi-view playback, or 3D display are special viewing devices to project a motion image into a realistic three-dimensional field. Every other day 3D movies became popular. In the late 1990s when several show On TV used anaglyph technique to attract viewers and increase ratings.
For the last five years, 3DTV sets are those that can operate in 3D mode with special shutter glasses to create a stereoscopic image is the new trend. These new TV sets usually support HDMI and a minimum refresh rate of 100Hz and great contrast levels.
As of March 2012, Toshiba, Samsung, Sony, Philips Panasonic, and LG all introduced their 3D capabilities and the price of them really comparable to the standard 2D TVs. 3D Blue-Ray players and DirecTV 3D broadcasts are also getting popular too.
Stereoscopic imaging dates to the beginning of photography. In 1844, David Brewster introduced the first stereoscopic device called the Stereoscope, which could take photographic pictures in 3D. 3D movie development was also dates the same times. In 1855 the Kinematoscope was invented, and the first anaglyph movie was produced in 1915.
There are several ways to produce and display 3D video.
Most popular 3D display technology for plying stereoscopic image pairs to the viewer include:
- Anaglyphic 3D (red-cyan or red-blue glasses)
- Polarization 3D (passive polarized glasses)
- Alternate-frame sequencing (active shutter glasses/headgear)
- Auto stereoscopic displays (without glasses/headgear)
- 3D TV without glasses
In October 2010 Toshiba announced the impending arrival of the first commercially available 3D TV without glasses models clearly telling us what is going to be the future of 3D TVs.
