3D TV Frequently Asked Question


This year the big buzz is all around 3D TV for sale. Although 3D TV is an emerging technology, it is already well developed, and all manufacturers will soon have us abandon our new HD TV to switch to 3D. So, so are you ready?

Here are 10 answers to common questions you may have following the emergence of the new 3D technology that will revolutionize the way we watch television at home.

1 - What is 3D TV?

3D Television technology allows a means to display on our TVs, programs, sports broadcasts, movies and stories in 3 dimensions. This is a stereoscopic effect giving the illusion to the audience of a dimension of depth in addition to currently available two dimensions: the height and width.

2 - How can I get the 3D effect from a classic 2D screen?

A 3D TV displays content in 3D, showing two distinct images of the same scene simultaneously, one for the right eye of the viewer and one for the left eye. These two images were filmed by two separate cameras of 6 cm, that is to say, the average space between our two eyes.
The two images then appear in full screen, intertwined. The objects, shapes people therefore have a slight asymmetry to the naked eye, but with the 3D glasses that is hidden from the viewers eyes, they see only the image dimensions.

3 – How does the new 3D TV compare to 3D movies that have existed for many years?

If you've experienced 3D cinema movies with 3D glasses with the famous red and blue, you may remember that the image quality was not of the highest quality. With "active glasses (sealing turn left eye and right eye), the resolution is doubled, because each eye sees a full image, the color rendering is also much more realistic with the new 3D TV .

4 - Will 3D TV be comparable to 3D movies in the cinema?

The technologies are almost the same and made as good. The only difference is the actual screen size at home is obviously smaller. As a result, some manufacturers recommend viewing a little closer to the screen to get the best effect.

5 – Can everyone watch TV in 3D?

No, between 5 and 10% of people suffer from stereo blindness. In everyday life, they normally perceive depth, but are insensitive to the stereoscopic effect. However, if they wear 3D glasses and watch movies on their 3D TV, the program will just appears in 2D.

6 - It seems that the 3D TV causes headaches.
 Is this true?
Most viewers do not suffer adverse effects, but some long-term exposure can cause headaches. User comfort is a priority for manufacturers of 3D TV. Producers of films for children must also take into account that their wards are closer (5 cm) than adults and create content that is filmed at a slightly less distance.

7 – Does the entire family need to wear glasses to watch a movie together?

Indeed, every viewer will wear 3D glasses to enjoy the show, otherwise they will see the distorted image and it will be very uncomfortable viewing. Today, viewers can not watch a 3D TV without glasses, but research in this direction is progressing rapidly and this will be possible within 10 to 15 years.

8 – Can a person who wears glasses also watch 3D TV?

Yes, the 3D glasses are provided to fit over prescription glasses and it does no cause discomfort.

9 - Do I need a new TV?

Yes. Current definitions can be enhanced to display 3D. The slow response LCD processing power requirements of new phosphors and the inability to accept the input signal (120 Hz) are the main reasons.

10 - Should I also get a Blu-Ray and game console?

Yes, except if you own a PlayStation 3 that will offer a special update by the 3D in 2010.
