Experience a new dimension in television with 3D TV, a revolution in high definition home entertainment. Watch films, view sports or play video games on LED LCD and plasma 3D televisions. Here's what you need to know about 3D TV.
What Is 3D TV?
Three-dimensional television, or 3DTV, lets home viewers experience movies, games, and other video content in stereoscopic (three-dimensional) effect. It gives the illusion of a third dimension — depth — to current TV display technology, which is limited to only two dimensions: height and width.
How Does 3D TV Technology Work?
To understand how 3D technology works, it helps to know how human vision works:
Getting the 3D effect at home involves tricking the brain into doing similar with the images from a television.
Can Everyone See 3D?
How Many Types Of 3D Exist?
There are three main 3D technologies:
- The original form of 3D that you need to wear glasses with red and blue lenses to see
- Forces each eye to view slightly different images by filtering colour. The brain overlaps them for the 3D effect. Not ideal for retaining the integrity of colours
Stereoscopic Passive Polarised:
- For environments where the screen is larger than the viewers' field of vision (e.g. IMAX)
- Suffers when you are either not front-on to the screen or tilt your head because the passive polarised glasses split the image, which is then lost
- Delivers full High Definition 1080p 3D imagery, ideally suited to the home environment
- Sharper images and better colour reproduction because a flat screen at home is much smaller than a cinema and occupies a less of the viewers' field of vision
- Active glasses use shutter technology for each eye that works together with the display panel. LG also offers 3D TV glasses that are passive
Do I Need A New TV?
Yes, as no manufacturer claims any of their TVs are upgradeable to support the new 3D technology.
What Options Should I Look For When Choosing A 3D TV?
3D TVs are available in Plasma, LCD, LED-LCD, and OLED display types, ranging in sizes from 32-inch (81cm) through to 84-inch (213cm)
- All new 3D TVs offer full HD 1080p and a minimum of 100Hz refresh rate
- The better the refresh rate, the better the 3D experience on a HDTV
- For viewing fast-moving action like sport or movies on LCD or LED-LCD, look at 200Hz
- For viewing fast-moving action like sport or movies on plasma, look at 600Hz options
Do I Need To Wear 3D Glasses?
Do I Need To Watch Everything On TV In 3D?
All 3D TVs can run in 2D mode and still deliver an exceptional 2D picture quality.
