Even those who saw the 3D-only films in the cinema know that to view they require special glasses. This is due to the fact that displays two synchronized time-channel video, and each eye should see only one of them. In cinemas used for this purpose anaglyph 3D-glasses.

This is probably the most well-known stereo-glasses – they have one glass blue, and another – red. They make the “invisible” part of the color spectrum; each eye receives only the portion of the image that is not filtered by a lens. Their dignity in simplicity: you do not need a 3D-projection TV or any display allows full viewing of the video. Disadvantages are obvious – loss of color, darkening of the image. All these disadvantages are offset in the cinema, but not at home.

Because different companies use different methods of video compression, each 3D-TV coax their stereo glasses, designed to show exactly this particular TV. More than a simple technological solution – the use of polarized glasses. In this light, which emits a 3D-TV display, and 3D-projection can be filtered so that each row of pixels gave light to the same direction of the polarization vector. To reproduce the stereoscopic 3D-video, such as Blu-ray 3D-player in a polarized screen, left and right video frames are converted into an interlaced format.

However, today this inexpensive way is not popular with manufacturers – polarization filtering is seldom absolute, which causes blurring of the contour image. In addition, the polarization technique assumes that the audience will sit in the center of a strictly 3D-TV. More often in stores you can find the so-called active shutter glasses. The LG 55lx6500 uses these as does the Mitsubishi WD-60638.

3D-TV, displays and 3D-projection of the last generation capable of displaying 3D-video so that the individual frames to the left and right eye alternate with each other. To avoid flicker, refresh rate increase. TVs, displays and projectors with alternating frames give better picture than the polarization (it’s about as 3D, and 2D-video).

3D-TV with alternating frames comes in a pair of goggles with active shutter based on liquid crystals. They receive an infrared signal synchronizes with the base station that allows you to block the left eye when a 3D-TV launched shot to the right eye and vice versa. Pts. with active LCD shutter allows you to watch videos in full resolution with a very sharp and clear 3D-image, and, moreover, are not sensitive to viewing angle.

And finally, the last date to date technology – 3D-TV DLP like the wd-60638. They also use active shutter glasses for video with a standard frame rate of 120 Hz. It should be noted that not all players Blu-ray 3D compatible with existing DLP 3D TV – for their connection may require a special adapter.

Today, manufacturers offer a simpler and more expensive and high-quality options for home 3D.

LCD TVs 3D-CRT with conventional lighting does have one important advantage – they are cheaper. In addition, they are distinguished by the small thickness of the panel, low power consumption, quality and comfortable to the eye image. Buy some models now possible and for 30 thousand rubles.

Particularly is extensive 3D-equipment segment of the plasma. Such models are free from defects flicker, refresh rate they are generally higher and the thickness of the transparent layer by plasma cells in the advanced plasma panels is reduced so that the effect of splitting the picture you can just forget it. The plasma panels are now positioned as the Full HD 3D. This technology is implemented, such as plasma screens NeoPDP company Panasonic.

Without significance and size of the screen. What it is, the stronger the stereo. That this is due to increasing interest in 3D-projectors and home theater systems. Today, for their production are widely used just three technologies: DLP American Company Texas Instruments (e.g. Mitsubishi WD-60638 uses this technology), LCD and HDMI 1.4v. Each of them has its advantages and disadvantages. 3D-DLP projectors have a resolution of 1280 x 800, is not compatible with all 3D-players. Sometimes the only source of 3D images for these projections is a computer equipped with graphics cards, NVIDIA.

For LCD 3D-projection projectors frequency of 120 Hz is still difficult to reach. Until the fall of 2010, there were only one 3D LCD projector – CF3D company LG, which managed to circumvent an obstacle in frequency. To create full 3D engineers LG complement one lens with two projectors running on a conventional 60 Hz.

And finally, the fall appeared 3D-projectors HDMI 1.4v, compatible with future 3D Full HD sources. The most significant contribution was made by the company Optoma; presenting a converter to connect to Full HD sources via HDMI 1.4v connection of all previously created 3D DLP projectors.

However, all these 3D-projectors have common weaknesses: 3D projection mode requires increased lumen output projector and discard one of the major achievements of recent years – the imitation of the contrast (dynamic contrast or virtual). Best preserved at a higher brightness contrast on DLP projectors, and the brightest of the new 3D Full HD projectors – Sharp XV-Z17000 with a luminous flux of 1,600 lumens.

Since there is still no single standard, and the prospects for each type of three-dimensional image (in terms of its preparation) is assessed by different manufacturers, on the market we see a huge range of glasses. And every glass is only suitable to your TV / equipment i.e. the LG 55lx6500 has glasses that would only work for it – likewise for the Mitsubishi WD-60638.

The easiest option of a stereo image, which immerses us in the three-dimensionality, all surely knows. Even in children’s comics can be found pasted paper glasses with red and blue “glasses.” Plus technology – certainly simplicity and low cost equipment. Cons – Lack of depth three-dimensional image, the distortion of colors.

A more complicated scheme conversion 2D to 3D with polarized glasses. For example, in IMAX theaters at the entrance to the hall illustrious name such spectacles. On-screen broadcast a special image captured with two close-facing cameras (distance approximately equal to the distance between human eyes). The polarization of left and right filters has different directions. This avoids problems with color perception of the viewer, and the quality is noticeably better. Needless to say, that this approach significantly more expensive.

Polarizing of glasses

However, in the pursuit of image quality, the inventors have gone further. Shutter glasses. Points of diversity over time show a picture for each eye. The process requires synchronization shows and spectacles. But the main problem is to increase the frequency scan TV – the viewer want to show twice as many frames. For each of your eyes. However, this restriction was passed. As usual, we had all the charm of novelty felt computer gamers. Monitors sweep frequency 120Hz predate 3D TVs. Manufacturers are not sitting on the ground and that’s a vivid example of a leader in the processing of computer graphics – Sunglasses NVIDIA GeForce 3D Vision.

Coupled with the 22 “monitor the whole set is cheaper $ 700. However, remember that you need a more powerful system unit. If not, the price is really a full set will be more. The wd-60638 is a good TV with relatively cheap glasses.

The idea of ​​creating three-dimensional images and to use it in everyday TV is not new. Significant obstacle to the implementation of this scheme has been compute power and size of the visible pixel. The second problem the company handled more quickly. Prototypes were created before, but the quality and clarity, they boast they could not compare to today’s models such as the Mitsubishi WD-60638.

For normal images, which are already accustomed to ordinary people, who want to process several hundred thousand pixels?

To date, manufacturing companies use several methods to create three-dimensional images. The essence of them in any way is reduced to obtain images from multiple sources, shooting. Even the two cameras are not enough for that, since the subsequent reduction of images into one will provide sneak preview just exactly in front of the screen. A man stands to deviate at some angle – 3D-effect disappears or is destroyed.
Reduction of the images are then interleaved frames from one or the other chamber. This problem is minimal on the LG 55lx6500.

Football match. A special camera takes stereo images, which you can then watch on a 3D-TV like the wd-60638.
To date, 3D-TV for itself is also significantly different in the way of its view. In most cases, it requires special glasses that come with the TV. But there are options, to get it without an optional accessory. There are prototypes with a special ribbed lens that allows plunging into the three-dimensionality that is not wearing glasses.

3D effects. Will I see or not?

Immersed in three-dimensional space is very interesting, seems so unusual, and everything that happens is extremely exciting. However, each person is very different vision. Since both types of play 3D and too much of all this creates a lot of positive and negative feedback. Moreover, it is believed that the 3D-film simply harmful. The decision is up to you, to buy or not to buy.

Although this year the number sold of 3D-TV‘s and did not reach the previously predicted grades, by the year 2014, experts believe, it is bound to step over a boundary in ninety million copies.

A team of researchers Display Search has updated its own report on the proposed sale of 3D-TV and published them. Analysis Group suggests that the number of sales of three-dimensional TV panels like the Mitsubishi WD-60638 in 2011 is unlikely to be greater than 3,2 million. But, two years after the sale of this type of technology will rise to ninety million. The same situation is also observed in the industrial sector: the number of produced 3D-TV with respect to conventional TVs will increase from two (data from 2010) to forty-one percent (projections for 2014).

Currently what is happening in the market 3D-technology, similar to the battle between producers and buyers? On the one hand, everyone knows that in 3D-technology is the future – the producers do not tire of reminding about this on occasion and without. On the other hand, users scare too high prices and poor selection of goods. In addition, buyers have long been accustomed to this state of affairs when the first value in the advanced technique overestimated, and after the product offer for a lot less expensive. It is logical to assume that the consumer market is waiting for the fall in prices, it trained for this.

Another interesting detail: the mandatory use of 3D-TV 3D-glasses are buying in smaller quantities than the actual panel TVs like the LG 55lx6500. It looks more than strange, especially considering that one 3D-TV is recommended to buy at least two pairs of special glasses. In addition, three-dimensional functions today has any modern model of television, are popular. The store will not meet television technology with premium, which would not support 3D-format.

Production Companies really set out to develop three-dimensional technology in their own industry. And because leading experts and analysts believe the unprecedented growth in popularity of technology 3D-formats, as well as the rapid development not only for its industrial production, but also advanced technology, set it at the service. Ahead and producers, and buyers expect new discoveries, new developments and, consequently, lower prices.

3D effects. Will I see it or not?

The decision is up to you, to buy or not to buy.

The source of stereo for 3D TV, usually a 3d Blu-ray player. Firms that sell 3d TVs, as the advertising offer player as a gift to all buyers. In addition, as a source for their work, you can use home theater 3d Blu-ray. This equipment can also be used as a stereo source, i.e., for watching movies. The task of manufacturers of these types of TV viewers interested in the quality of their view that would lead to an increase in the number of films shot in 3D format. And those buyers were able to immediately assess the picture quality, they offer a gift drives Blu-ray.

Also, the stereo broadcast some TV providers, for example in the present moment you can find several channels operating in 3D format. You should not lose sight of the fact that today there are video game consoles are also working in 3D format.

TV 3d device, implies a process that manages the system. Thus, the most modern and powerful model is to help yourself to convert an ordinary picture into a 3d format. A 3d effect is achieved by using special glasses. Having this opportunity will help you to watch many films, in the absence of 3d discs.

Typically, when you buy 3d TV, people are most interested in is this function, and this requires a special interface that can convey such a clear signal. In this case, the optimal choice of the interface is HDMI v1.4 +3 D. It is also possible to connect via the USB port, which provides an opportunity to work directly with the carrier.

However, these interfaces are suitable for use with other images. Although, some models have built-in media player. The presence of additional types of interfaces will help you use extra equipment or sources.

Do not forget that in addition to playing 3d images, your TV will serve as a standard TV. This means that the set of its functions should meet your needs. Choose a model based on the principle of need, the higher the number, the better. The only exception is the response time; otherwise you will have to wait very long.

Today an increasing number of domestic equipment should work with technologies such as LAN-network and Wi-Fi, with their help you can easily go on the internet like the LG 55lx6500. Also, by connecting to a TV home computer and other equipment, you will be able to use them as a source of images.

Finally, I would like to mention a luxurious design of the case, because today people like to surround themselves with beautiful things, because they are part of our interior.

3D TV without glasses should appear in the near future, but not a fact that consumers will be delighted by novelties. One thing is exactly what many manufacturers have already begun to develop technology to then implement it into mass production. Even the not so widely promoted companies already have 3D TVs and they do actively sell them, on the market, but most buyers are complaining that they have to use 3D-glasses, and it is extremely inconvenient. Therefore it is necessary to develop a new technology that will enable us to watch 3D-movies without glasses.
New technology is already there, it was called 3DF IP, and it is the development of the company 3DFusion. It is worth noting that new technology really pretend to be revolutionary, because the user can adjust the depth of the image for more enjoyment of watching movies. While this technology is enough cheese and is under active development, but soon the company 3DFusion will be ready for mass application of technology in their products.

To accelerate the company openly declared the need for external resources, and I must say that attention has not been deprived. Interest in new technology is, as there are people who are interested in the mass application of this technology in the latest 3d-TV. So the hope is that soon it will be possible to do without 3D-glasses.

There are several types of 3D TVs and their sources. The fact that companies engaged in manufacturing of televisions, releasing them in two versions: LCD and plasma TVs. Thanks to what people can choose 3d TVs in the most convenient option for themselves.

Choosing 3D TV

If the space of your room is small, it is best to buy a model with 40-47 inch diagonal. Otherwise, we should not shy, and boldly purchase 3D television sets with more than a diagonal of 50 inches. Due to the large screen you can view the TV big enough company. As a rule, people prefer in such cases to acquire the plasma panel. With regard to the characteristics of the screen, then it is obligatory Full HD.

3D – an abbreviation of the word “three-dimensional». Objects in the real world actually have three dimensions, for example, we can measure the length, width and height of the object. If we look at objects in the real world, it will easily be able to estimate their height and width (two-dimensional view of the object), but we can also perceive the depth of the object and the distance to it.

3D TV glasses

We see the world with two eyes. Since the eyes are not in one place, and a little separated from each other, each one receives slightly different perspective on the subject. Typically, two images are combined by the brain in one, but if you close one eye, you get just that image that sees the other eye. Notice how different perspectives of closely spaced objects for each eye.

Although each eye receives a slightly different picture, we do not get two separate images. In our stereoscopic view of the brain combines the image of each eye in the holistic perspective, and this combined image already contains a three-dimensional objects and a sense of depth. Charles Whetstone first described stereoscopic vision in 1838, but artists and scientists engaged in three-dimensional perception for many centuries before.

Perception 3D

Humans (and most predators) eyes are on the front of the head. Such an arrangement improves the perception of depth, allowing the hunter to better measure the distance to his victim.

In addition to stereoscopic vision, a sense of depth and yet sum due to monocular “signals” of depth (these “signals” of depth may be provided by only one eye, or to be more precise, 2D-version of the picture that you get). Such “signals” of depth is very important for a good 3D-vision, because your brain expects stereoscopic perception is closely related to 2D-perception of viewing the scene. 3D TV’s like the LG 55lx6500 employ such techniques.

In the previously used models of surround video (CRT televisions, projectors) applied the principle of dividing the image resolution in two. And one frame stereo when the SIM even lines, while another frame in odd rows. With this method of dividing an image resolution of CRT TVs in the vertical dropped to 300 lines. And in the case of Full HD would drop to 540 lines if the native resolution of 1080 pixels vertically. Display an image to each eye separately, and at one time one of his eyes had seen his half-frame, and the other during this time saw nothing. In the next half-frame was just the opposite, and have the other eye saw the image, and the first not.

To ensure resolution of HD televisions in 3D, that is 1080 pixels vertically, you can apply the same principle as before show alternately separate frames for each eye. At the same time make it so that each frame would have seen only one eye and other eye had already seen her, that is, the next frame image. Example models are the LG 55lx6500 and wd-60638.

In a normal TV to the technology staff will come with a frequency of 25 Hz, because the frame rate of 50 Hz there and if you divide the image to each eye and then get 50:2 = 25 frames per second. And if movies are in theaters at 24 frames per second, and there we see reflected light from a distance. In the TV at a frequency of 25 Hz flicker is noticeable and will hurt your eyes. If we take the mode of 24R, implemented in modern television sets for viewing movies with just 24 frames per second, then it’s really the frame rate takes a multiple of 24 and is 72 or 96 Hz.

It turns out that the Full HD 3D cannot normally be played on conventional HD LCD TV. For comfortable viewing of the correct frequency of 60 Hz for each half frame (a value derived from research), a common frame rate should be 120 Hz, and thus even 100 Hz TVs are not suitable for displaying 3D. In this case, each frame must be displayed with a resolution of 1920×1080 pixels, which corresponds to Full HD.
