Pros and Cons of Three Different Display Methods For Getting a 3D Image

Most of the current model Tvs Create 3d Images by rapidly displaying two slightly different images for one frame of animation. Active shutter glasses block the view of the eye that is not supposed to see the image by darkening the lens over that eye. The world has depth because each of our eyes see it from a slightly different perspective. When the two slightly different images are shown in this way the brain is fooled into seeing an image with some depth to it.

The glasses you need for this experience can be expensive. A TV capable of the high refresh rates required for 3D display is also a necessity. The TV you bought 4 or 5 years ago probably won't be 3D capable so you will have to fork out some serious cash for a new one. Once you have the TV you then need to get glasses compatible for your model. If you're like me and you want to watch movies with your family then you are going to need a few pairs. Essentially this can mean putting almost the same amount of money you spent on the TV just to get enough glasses for each family member.

Thankfully technology moves onward and upward at a great rate of knots and new equipment is already coming into the market place which promises to solve all of these problems. New technology always costs more but TVs are becoming available that use polarized light to display the images. This is the same technique used in the movie theaters but on a smaller scale. Movie theaters work by projecting the image with polarized light. Polarized glasses only let one image through per lens thus allowing each eye to see one image each and each slightly different from the other. Refresh and scan rates are not as crucial as both images are shown at the same time.

For mostly solo viewing you can purchase LCD screens for 3D viewing without glasses. Through clever and secret use of technology the LCD screen is capable of displaying the two different images in such a way that each eye only sees its correspondingly correct image and all without glasses. A major disadvantage of this technology is that it is not suitable for a widely dispersed audience. A viewer must be seated in the correct position to enable each eye to get its correct image. Any viewer outside of the sweet spot will only a see a 2D image at best or a blurry mess at worst.

We might not see it for a while on a large scale on big TVs but it is available as a cool 3D effect for games on the new <a href="http://www.3dsgamesystem.com/">Nintendo 3DS games system</a>. As there is usually an audience of one with a personal gaming system then this technology is an excellent way to bring 3D gaming to the masses.
