3D-TV in 2011

Everyone knows that latest plasma TV or LED’s is produced with 3D effects. They have created a revolution in 2010, and this revolution will only develop further in 2011. The latest revolution in 3D TV is that there is no more need of the 3D glasses. Always watch TV with a boring glasses on your head is obviously not practical. Several manufacturers have now announced the technology in your hands in order to produce 3D TVs that do not need a 3D glasses.

What is 3D TV?
3D TV is a television special television that allows the images to three-dimensional view. Although the real hype around 3D really started in 2010, there is a principle about it much longer. Already in the 80s of last century there were already several films to be viewed in 3D, both in cinemas and on TV at home. The reason why 3D is so popular television only now is the higher quality of the images. These can now be viewed in HD or High Definition.

How does it work?
A modern 3D movie is filmed with a camera with two lenses. Emerge as two images, each a few inches apart. In one image, the filtered red color, green in the other image. When we set up a 3-D glasses with one red on one side and on the other hand, a green lens, it seems that we see the image in 3D. Seems, as it is still an illusion of course.

3D TV without the 3D glasses
Several manufacturers have already announced that they have the technology to enable 3D viewing without glasses. This technique, however, lasted much longer than today, but was never really on point. In the past we managed to create 3D effect only when the viewer was in front of the screen. Now the market include Toshiba, Samsung and Philips to change that. The technology was already used in various smart phones and the new Nintendo 3DS .
