ZOOM Choice: The Best 3D TVs.

Stereo cinema has a fairly solid history – it existed in the analog era, when everyone was filmed and watched with the help of film projectors. In the Soviet Union, since the 70s, there was a special NGO “Stereokino”, which was engaged in the production of stereofilms. But over the entire period of its existence, this type of visualization has undergone many changes.

Only the need to wear special glasses remained unchanged, although today there are samples of technology in which this problem is also solved. However, all popular technologies today involve the use of 3D glasses. This is necessary in order to separate the information targeting the left and right eyes.

In other words, so that one eye does not see what the other sees and vice versa. Due to the fact that each eye sees only its own picture, slightly displaced relative to the picture for the second eye, we get the effect of three-dimensionality.

3D technology.

Today, there are three main technologies for forming a stereo image: anaglyphic, polarizing and shutter. In the first technology, a three-dimensional image is obtained by color separation of frames intended for the left and right eyes..

Anaglyph glasses have color filters. The advantage of anaglyph is that such a video can be watched on absolutely any screen. A significant drawback is the loss of color in the image, because part of the color spectrum is used to obtain the effect of volume.

Anaglyph glasses have color filters.

Another technology in which glasses are conventional light filters is polarizing. As the name implies, the separation of frames for the left and right eyes is due to the effect of polarization (the vibrations of light waves oriented in space). In cinemas, a polarizing picture is produced using two projectors.

In home appliances, and even more so on a regular flat display, this effect is quite difficult to obtain, therefore this technology is not used in TVs..

Polarized glasses work on the principle of oscillation of light waves.

The third way to get a three-dimensional image, and more specifically, to solve the problem of separate display of frames for the left and right eyes, is quite simple. The shutter technology or technology with active glasses works as follows: the TV screen alternately displays “left” and “right” frames. Active glasses, synchronizing via IR communication with the TV, alternately close one or the other eye.

Since the frame rate and, accordingly, the speed of closing the eyes is extremely high, there is a feeling that we see a three-dimensional picture a little less bright than without glasses..

Active shutter glasses require synchronization with the device.

Are there any problems caused by the chosen method of obtaining a 3D effect? Yes, of course, like any new technology, the bolt action has minor drawbacks and limitations..

First, the IR emitter in TV and the IR receiver in glasses can lose sync if you turn away from the screen or just look around too actively. Secondly, the frame rate in 3D mode is only 50 or 60 Hz, from which we, spoiled by 200-600 Hz scanning, see the picture flickering like on an old CRT TV. This same effect provides faster vision fatigue and limitations on the use of 3D by children and adolescents. Third, depending on the quality of the technology implementation, the effect of interlacing and contour bifurcation may appear when displaying fast motion.

Such artifacts appear at the moment when there is a slight shift in synchronization when changing frames and opening / closing the shutter. One eye manages to see the disappearing picture, which was intended for the second eye. All of this is worth paying attention to when choosing a 3D TV.

We offer our review of the best models of this summer..

Undoubtedly, all 3D TVs sold today will be used for a significant part of the time as the most common 2D TVs, so developers pay a lot of attention to traditional consumer properties of products..

3D in LCD TVs.

The first 3D TV we are considering is the flagship of LG’s current lineup, the LG 47LX9500. Among its colleagues, both 3D and 2D, the novelty is distinguished by an exceptionally light and elegant design. Thin screen bezel, slim body, single front surface, transparent support and translucent screen edges make the TV visually weightless. But with such exceptional slenderness, the LG 47LX9500 is not at all as simple as it might seem at first glance. The backlight of the matrix is ​​not the usual side EdgeLED, but a more advanced background FullLED.

This brings the work of dynamic contrast closer to real contrast, because the backlighting of dark areas of the screen can be turned off while brightly lit objects are backlit.

The matrix of the screen of the LG 47LX9500 is the most modern available, 10-bit, which gives a fairly large color depth. As befits any modern TV, LG 47LX9500 has the ability to access the Internet – to a rich set of all kinds of widgets added the ability to make video calls in the Skype system. However, any of the participants in today’s review can boast of all this.

In turn, what not everyone has is a built-in multi-format media player that allows you to play literally any content from USB media, including HD video in an MKV container.

3D capabilities are implemented in a rather original way. The TV comes with a pair of active glasses on sale, but the sensor for them is not built into the case, it is supplied separately and can be installed both on the TV and in any convenient place next to it.

LG 47LX9500 – the flagship of the 3D line of LG.

The technological capabilities of the Sony KDL-40LX900 3D TV have gone far beyond the usual Internet and media capabilities. Even built-in Wi-Fi seems to be commonplace when it comes to facial recognition. This TV literally knows its owners by sight and reacts accordingly. If you move around the room, it will adjust the picture so that it looks better from where you are now.

If you leave the room, the Sony KDL-40LX900 will turn off the screen, leaving only the soundtrack and turn it on only when you look at it again. If children should not watch any TV channels or simply should not come close to the TV, he will control everything himself..

Sony KDL-40LX900 – minimalist style suitable for 3D viewing.

Another thing that is impossible to keep silent about is the amazingly stylish design. The minimalism of the black monolithic screen is absolutely simple rectangular in shape, an incredible amount of style is invested. Aesthetically speaking, the Sony KDL-40LX900 is simply flawless.

There is no need to worry about the picture and sound quality. In this matter, Sony did not even think to give up positions. With a simple EdgeLED backlight and properly selected screen filters, the developers have managed to achieve exceptional contrast.

When you buy Sony KDL-40LX900 you get a pair of sets of 3D glasses, the sensor is built into the TV, so nothing will spoil the beauty of this technological masterpiece..

LCD Against Plasma.

The 3D performance of LCD TVs is truly impressive. The tangible, literally tangible volume of the picture will not leave anyone indifferent. However, it’s worth checking out 3D plasma TVs to realize that the technology’s potential is just beginning to unfold..

As you know, plasma and LCD differ from each other by the absence or presence of “flickering” of the screen. Plasma cells flash and go out, while liquid crystals simply change their color with a constant glow of the backlight. When working with 3D, the consistency of the LCD TV’s luminosity, which the developers were so proud of, played a cruel joke on them.

Plasma at the moment of transition from one image to another has time to go out, which means that at the moment of switching the shutters in glasses and changing the frame on the screen, we have



much less chance of seeing the picture shown for the other eye. On the LCD, this problem can be noticeable when displaying fast movement – the contours are double or have jaggedness.

Over the past couple of years, the quality of branded plasma panels has grown significantly, so the Samsung PS50C6900 plasma TV is able to please the most demanding moviegoer with a picture, brought up on the best plasmas of the past years. The new technology for manufacturing the Clear Image Panel screen has significantly reduced the thickness of the transparent layer in front of the plasma cells. Thus, it was possible to get rid of the effect of a layered, bifurcated image. In addition, the brightness and clarity have increased. In terms of the number of Internet services and multi-format built-in media player, Samsung PS50C6900 is not inferior to the most advanced LCD model.

The Allshare service is also supported, which allows you to view content on the TV screen from a laptop or home PC..

When purchasing Samsung PS50C6900, the user will receive a 3D Blu-ray drive.

Those who are ready to buy a Samsung PS50C6900 solely for 3D will not be disappointed – the TV will come with not only a pair of active glasses, but also a Samsung BD-C6900 3D Blu-ray player. The latter will be especially relevant not only because there is no need to buy a separate source, but also because you can use the new BD Wise function, which automatically adjusts the TV and player to each other depending on the type of content being played..

Panasonic VIERA TX-PR50VT20 will allow you to go online and watch 3D.

We will not go against the truth if we say that the older Panasonic plasma TVs have rightfully occupied the niche of premium plasma TVs, in which Pioneer reigned so long and unchallenged. In the most common 2D mode, the Panasonic VIERA TX-PR50VT20 is exceptionally good. The new technology for the production of plasma panels has made the interpixel distance shorter, the contrast is higher, and the picture is of better quality. The TV does not surprise with a large number of additional options, although it is possible to use Internet services or view photos and videos directly from a memory card. The main value is the image and Panasonic VIERA TX-PR50VT20 shows itself in the best way both in 2D and 3D mode.

The main feature of working in 3D is a special shutter glasses operation algorithm, selected in relation to the peculiarities of the plasma panel operation. When viewing 3D on this particular TV, the appearance of any artifacts is completely excluded.

The full-fledged form of the new technology can be seen not earlier than in a year, so you can take a closer look at 3D without haste. Whichever 3D TV you choose, keep in mind that the ability to display stereoscopic video is one of the many possibilities. Image quality, functionality, design are still relevant.
