Review of 3D TVs: We’ve had enough?

By modern standards, the history of television began a long time ago. Scary to think about: the first working sample of receiver, which receives and plays back video remotely, took place at the beginning of the XX century. The first device that implemented the principles of modern kinescope TV was shown to the public back in 1906! True, television did not play any significant role in public life until the end of World War II, although there were experimental broadcasts in the USSR, Europe and the United States.

Big spoonful of tar

So stereo video playback technology does exist and is well proven. What’s next? Like with Full HD to “lick” the technological processes and accumulate content? In this case, that approach might not work. And the main argument against this would be our own brains.

Essentially what happens when you watch 3D video? The brain is presented with two flat pictures, and the attempt is made to convince it that this is a single three-dimensional image. Everything would have slipped through, as it did with stereo sound, but our eyesight is significantly more discerning than our hearing and more dodgy than the engineers who develop 3D TVs would like.

The fact is that besides the “obvious” perceived work of our brain and eyes to retrieve optical information from the environment, there is also the “non-obvious” one, which we do not notice. In particular, there is such a phenomenon as optical tremor, which is the super-fast spontaneous movement of the eyeballs. It happens so fast you can’t even see it, but every second our eyes roam over the whole field of vision, probing it. As a result of eye tremor, the brain receives the primary surface information, and then refines it through a detailed analysis of the images that come from each of the eyes.

What happens when we watch 3D video? Each of the eyes transmits information to the brain about the frame it sees. As a result of analyzing two frames they are different , the brain concludes that the three-dimensional objects in front of it. But each eye, scanning the space in front of it, in the process of tremor determined that it is looking at a flat screen.

A contradiction arises. The brain, searching for processing errors, starts to analyze incoming information more intensively and thoroughly, overstrain itself and start to ache. At the same time, it makes your eyes scan the space more closely. As a consequence, tremors become stronger and the eyes fatigue quickly.

And all of these problems lie in the principle of the construction of stereo images, improving the performance of TVs and glasses these problems can not cure. In fact, the very principle of stereoscopic video comes into conflict with the psychology and physiology of human vision.

And this leads to the conclusion that 3D video in its present form is not viable. Yes, TV sets with 3D functions are still produced the more so as they actually only differ from analogous devices without 3D software , but the interest to them both from the audience and from the manufacturers has already cooled down.

Now TV manufacturers are “getting on a new horse”. And the name of the horse that’s supposed to take them out into the happy, hassle-free tomorrow is Smart TV. But this is the topic of a separate article.

LED TV with Smart TV function

Officially launched in America in April 2011 as part of the presentation of LG Cinema 3D TV sets showing stereoscopic images using the “passive” FPR Film-type Patterned Retarder technology.

LG Electronics company presents on the American market LW575S TV set, one of the top models of the Cinema 3D series. The model differs from other representatives of the series by its front panel design.

The bottom metal frame TV has an original relief, also present a mirrored rectangular stand.
