In order to watch stereoscopic films at home, you need to purchase a new generation TV with 3D support. Technology, which creates a visual sensation of bulk, found its embodiment in modern models of 3D-TVs .
What is 3D technology?
Answering the question how to watch 3D movies on TV, one should understand the principle of this technology. 3D creates a three-dimensional image from two consecutive pictures with one scene. The first of the applied images is for the right eye, the second for the left eye. The images perceived with the help of special glasses are connected in the brain of the viewer, creating the illusion of a three-dimensional image.
How to connect a 3D TV?
3D-TVs - high-end models, programs on which you can view both in the usual format, and in 3D-format, while the image is different brightness and clarity. How do I turn 3D on the TV? To do this, you need a cable or satellite TV with a 3D function. To find out whether access to 3D television is ensured, contact the provider who will advise on the possibility of providing this service. Currently, quite a lot of 3D TV shows and films, broadcast either on cable channels, or on paid channels. The development of cable networks dealing only with 3D content is urgent now. It is impossible to redesign the old TV for stereoscopic operation, except for the projection DLP-type TVs manufactured by Mitsubishi and Samsung in recent years, as well as Samsung 3D Ready plasma devices - PNB450 and PNA450.
How do I set 3D on my TV to watch discs?
To play 3D Blu-ray discs, you need a Blu-ray player with stereo support, and a high-speed HDMI cable to connect the player. Some retailers attach Blu-ray discs to the 3D devices being sold.
How to watch 3D movies?
In order to watch TV programs and movies in 3D, special 3D glasses are needed. When viewing without glasses, the picture is doubled, distorted, which causes eye strain and makes full perception impossible. Experts recommend choosing the glasses of the same company as the TV. Although most often, 3D TVs are sold with glasses, but if you are not going to watch movies with a stereo effect alone, you will need extra glasses.
Types of 3D glasses
3D glasses provide a quality viewing of three-dimensional feature films and programs. Glasses for 3D-TVs have a normal, enlarged and large field of view. The frame is made of cardboard (cheaper models) and plastic. It is convenient to use dimensionless glasses, which can be adjusted if necessary.
Anaglyph glasses
This design glasses were used even while watching 3D movies about forty years ago. The filter for one eye has a red color, for the second one it's blue, so that the corresponding part of the picture for each eye is blocked, which provides a three-dimensional perception of the image on the screen. There is a certain discomfort from viewing, the more difficult it is to talk about the quality of the picture.
Polarized glasses
There are two types of polarization glasses: with linear and circular polarization. Circular polarization has advantages over linear: if you tilt your head in linear glasses, then the effect of the stereo disappears, with circular polarization, the volume of the image is not lost in any position of the viewer.
By the way, you can easily make 3D glasses with your own hands .
In recent years, you can buy TVs with the ability to view stereo images without glasses, of course, this technique is much more expensive.
