3D TV Sets

The basic concept behind 3D TV sets that allows the 3D effect work is to let your left and right eyes see slightly different images. This fools your brain into thinking that you are actually seeing real 3-dimensional objects.

In movie theaters you can watch 3D movies by wearing a pair of glasses that are polarized. The right eye and left eye see different polarizations. The projector projects images for the right eye and left eye sequentially. But a filter in front of the projector polarizes the light for the right and left images differently. The image for the left eye is polarized so only the left eye sees the image and the image for the right eye is polarized so only the right eye receives that image. The images come rapidly enough so you do not detect any flicker and see continuous action. This makes your overall experience very enjoyable.

3D TV Sets

3D TV sets must accomplish the same effect: displaying sequential images for the left and right eye.

There are two common techniques used to allow you to selectively view the proper image for each eye. Both use special glasses which you must wear while watching the 3D TV sets. But, the technology within the TV set and the glasses are different.

  • Active Glasses: One technology uses battery powered, active glasses to alternately open and close a “shutter” to allow or prevent light from reaching your eye. The 3D TV using an infrared signal to tell the glasses to shutter the left eye and open the shutter on the right eye or do just the opposite. This way, each eye sees the proper image and the 3-dimensional effect occurs. Active glasses are relatively expensive, about $75 per pair.
  • Passive Glasses: This is more like the movie theater. Here you wear polarized glasses, each lens polarized differently. A polarizing filter over the entire TV screen polarizes each image for either the right or left lens. The passive glasses are lighter and much less expensive. This technology makes the overall TV system more expensive that that used for the active glasses.

The TV still displays sequential images for the right and left eyes. But, now the glasses themselves block out every other image.

3D TV Sets are Special

As you can tell, you cannot make a traditional 2D TV into a 3D TV set because extra technology is required to detect right and left images and project them sequentially. The 3D TV set must then either emit an infrared signal to coordinate the active glasses or coordinate the polarizing filter covering the screen.

Today’s 3D TV sets are an innovative breakthroughs allowing for more exciting viewing of sports, theater, action thrillers and so many other types of viewing experiences. You will probably be amazed to watch 3D action scenes and realize how lifelike they really are.

Some more advanced 3D TV sets have fast processing technology that can simulation a 3-diminsional effect in older non-3D videos. This makes watching older videos more exciting, too.

If you are looking for your first 3D TV set, it can be a bit confusing. You should read about the technology, watch some sets in the store, and then decide which model is best for you. The future will only get better as other 3D technologies are perfected and prices make 3D TV sets more affordable.

Future 3D TV Sets

Current 3D TV sets require either active glasses or passive (polarized) glasses. But, the “no glasses” technology is on the horizon. Soon 3D TV sets won’t required special glasses.

Autostereoscopic TV is coming, some say in 2012. Autostereoscopic TV is now being used in major corporate offices to save on costs of meetings. Autostereoscopic rooms are used in multiple locations where employees can meet “face to face” and yet be thousands of miles apart.

Although this capability is cost effective only for large, national or international businesses, advances in technology will bring the price to reasonable levels in a few years. Soon, you will see autostereoscopic 3D TV sets in a store near you.
