3D TV - vagueness and technologies to market.

There's shop Ponto Frio Via Parque Shopping in Rio de Janeiro, Barra da Tijuca, there is an LG 47-inch TV that is the pinnacle of technology today. SAMSUNG TV with 3D technology, and virtually borderless ultra thin, very elegant.

When a prospective customer approaches the seller asks you to put the 3D glasses and sit in a chair in front of the TV to enjoy the 3D TV more comfortably. Been there and say with sincerity, the experience was amazing for me.

I have watched movies in 3D at the cinema and did not value the thing so far. See more like a cute effect but that the accuracy at least for me in spite of the novelty, not worth the investment because the price of admission to a 3D movie nearly doubles, and 3D effects I see them scattered and not continuous, with a impact or other effect.

Already I have seen the video demonstration of the 3D store in Via Ponto Frio Park was amazing. It was the best feeling I have ever seen in 3D. The 3D image catches the eye and sense of depth is broad and engaging.

Today you see advertising on TV I saw there at the Disneyland Hotel. See below. 

The price is inviting, and this is a different technology. "NANO" LED or an LED is smaller than the conventional one. Must have an amazing setting. If you think a 47-inch SAMSUNG TV FullHD LED that is not 3D nor cost R $ 3,000.00 (three thousand dollars), about three years. And obviously, because the industry still does not sell a lot of 3D TVs, the price must fall further. It is a matter of waiting.

The question that is asked however is: What will we watch on a 3D TV? I have not seen neither in nor for sale Rental 3D films. According to the article below, in the United States there are very few titles. And the cable TV they have only just put some HD channels, which are not Full HD, when will broadcast in 3D?

Ha! It is true that an American game will tranmit 3D. Unicast and exclusive to those who are the happy owners of this technological marvel, and has one open channel (ONLY) which broadcasts in 3D. The Bandeirantes.
But it just yet. Is that worth the wait?

What's worse is that there is currently a war between two patterns, as seen in the past war between Betamax and VHS, and remember that ultimately was won by the VHS standard. This time fight from one side to another LG and Samsung. It seems that LG will lead to better, but look at this battle osdesdobramentos column Ethevaldo Siqueira.

TV standards war between 3D 

Ethevaldo Siqueira

There are now real war between the two world's largest manufacturers of TV sets, Samsung and LG Electronics, both Korean and arch-rivals. The dispute, which seems to be coming to an end, will determine the very future of the global market for 3D. The winner will get the biggest slice of the market and its technology can be adopted by most manufacturers. 

So far, the 3D TV market has not taken off, as evidenced by the worldwide sales of 3D. Their results were disappointing in 2010 for the industry. It was expected to be sold 30 million 3D TVs, equivalent to 12% of total handsets sold worldwide (248 million receivers). Instead of the planned 30 million, were sold only 3 million 3-D television, which is only a tenth of the estimate. A real bucket of cold water for manufacturers. 

The industry, however, even before the results of 2010, reveals surprising and optimistic bet on a real explosion in sales in 2011: a growth of 1,000% over the previous year's sales. It is an overly ambitious expectation. 

The dream of the TV manufacturers in the domestic sphere is to repeat the success of 3D cinema, with films Avatar and Alice in Wonderland and the production of 3D equipment reach something close to 30% of world production by 2015. Today, more realistic question is made ​​by analysts: how to get to 30% of annual sales in the next 4 or 5 years, in 2010 was not even 1.5%? 


To achieve something close to a third of total sales by 2015, the 3D TV still need to win five major barriers: 1) the high price, 2) low content, 3) the aversion of many people by the use of special glasses, 4) the lack of options both in 3D broadcast TV (broadcasting) and by subscription; 5) the lack of standardization of the technology of glasses and monitors. 

1. Prices. The consumers of the class A and B are reluctant to pay the equivalent of U.S. $ 1.5 thousand to three thousand by televisions from 42 to 55 inches. Repeated here the old vicious circle: the 3D TVs are expensive because the industry sells little, little bit because the industry sells televisions are expensive. 

2. Content. Another crucial point is the relative lack of 3D content. The world would buy more if there were more 3D TV films, documentaries and high-quality broadcast TV programs in the technology. The few good movies available on Blu-ray disc 3D are still expensive. 

The increasing availability of 3D programs and games for kids and teens. A visit to the largest electronics stores in Los Angeles (as Fry's and Best Buy) two weeks ago, we found that there was more than a dozen films for TV 3D on Blu-ray. 

A few months ago, the first 3D Avatar discs were sold at $ 100. But now prices are falling below $ 70. Still, not excite most consumers still prefer to pay $ 25 to 40 2D Blu-ray discs, with good content and excellent high definition picture (2D). 

3. Active glasses. A major problem with the popularization of 3D TV is on the side effects of ultra sophisticated active glasses, which use batteries and micro-mirrors, adopted by some manufacturers, including Samsung and Sony. The images are excellent. But the malaise of an audience is unbearable. 

The problem of active glasses is recognized even by hand by manufacturers, whose warnings about its side effects are frightening. Among other problems, manuals remember to watch movies or TV shows with these 3D glasses for more than two hours can cause nausea, dizziness, cramps and burning eyes. And an advice to the user is not driving after watching 3D TV for over an hour. 

4. Delay in broadcast TV. Television has not yet discovered the 3D world. Rare are the broadcasters open (or even cable TV) that already offer 3D programs in broadcasting or cable. In Brazil, Rede TV is one of those few which broadcasts its programs on channel 9.2 in 3D. 

Amilcare Dallevo Jr., president of Network TV, proclaims: "We were the first broadcaster in the world to broadcast regularly in 3D." In the United States, the number of regular TV programming in 3D now stands at 20, out of more than 1,500 stations. The pay-TV networks also offer options for regular programs in 3D and begin to transmit large sporting events in the first place. 

5. Lack standardization. While the film has already adopted a standard consensus led by Hollywood, the TV industry still lives a real war of 3D technologies in both the monitors as the glasses. 


LG TV showed the standard 3D Cinema Exhibition in Las Vegas, 2011 

In the future, a horizon of 5 to 10 years, we will not need special glasses to see 3D TV and 3D cinema, with the best quality pictures. This is the unanimous prediction of the experts. Today, however, 99% of televisions require 3D glasses. 

The only exception is Japan's Toshiba, which offers the option of 3D TV without glasses. But this technology has not reached maturity, it requires the positioning of the spectator in front of the TV. Any change in position or angle of view affect the three-dimensional effect. 

Thus, the world now has only two technologies adopted by the vast majority of televisions sold in the 3D world: the spectacle of assets and liabilities. 

It's just good to clarify the meaning of each of these accessories. Active glasses are those powered by batteries and equipped with thousands of microscopic lenses that open and close dozens of times per second, in what is called scintillation or flicking - kind of a flasher to allow the perception of 3D images. Our eyes receive alternately the images that give us the 3D feel. Every split second, one eye receives the image while the other is the same blank time. 

The other new technology is that of passive glasses. Developed by LG, this technology is very similar to that used in 3D cinema. Therefore, the company named him TV commercial 3D Cinema. The great advantage of passive glasses are in fact not have the disadvantage of the Flicker (or flicking) image. 

The first TVs with this technology will be launched in July in Brazil. Daniel de Almeida, chief technology officer of LG Electronics, Brazil, reports that "the experience of watching TV with 3D glasses liabilities, excluding battery and lens wear is very different because it is much more comfortable: the images are much more stable and allow good vision at wider angles. " 

The confrontation 

On the initiative of LG Electronics and Samsung without the participation was promoted on June 1 in Los Angeles the confrontation of the two technologies in a demonstration of all the features of both formats. Before an audience of filmmakers and journalists, were displayed simultaneously movies and clippings with the best of each TV manufacturer, side by side, to be seen with both active glasses such as liabilities. 

Visually, the results of the TV system called 3D Cinema, were convincing: the passive glasses are much more comfortable than the active glasses. Side effects are much smaller. 

Cinema 3D TV system introduces a fundamental change on the TV screen LCD, which is the superposition of a film that introduces a form of delay in sampling the film, in English, Film Patterned Retarder (RPF). 

This film has the function of FPR enhance the separation of images for the right eye and left eye. Then they are combined with the help of passive 3D glasses (the same technology used in theaters), specially designed to receive each image, creating a three-dimensional experience more comfortable. 

Another advantage of 3D Cinema TV technology is the automatic conversion of 2D images in 3D - albeit with a slightly lower quality than the images originally produced in 3D, but with good sense of depth. And by acquiring a 55-inch TV with this technology, the buyer wins four passive glasses parts, weighing only 16 grams. 

The presentation of 3D Cinema TV technology and the confrontation with the technology of active glasses were conducted in Los Angeles by Humberto de Biase, director of marketing for LG Electronics Brazil, two weeks ago at an event alongside the Brazilian Film Festival of Hollywood. 

The demonstration underscored not only the quality, but mainly the stability of the image in comparison with the image of active glasses. In the opinion of the overwhelming majority of the audience, the new technology of passive glasses virtually eliminates the side effects of prolonged viewing of 3D TV, not causing dizziness, burning eyes or any other kind of malaise. 

From now on, war tends to be defined between one of two formats sponsored by Samsung and LG, followed by other manufacturers. 

The American Vizio, a manufacturer of televisions and consumer electronics manufacturers in China and joined the new television technology and the executives of LG since March are trying to attract to his side by Sony - a company that buys the panels and monitors from Samsung. 


Faced with this attack from LG, Samsung strikes back with their televisions and stereo glasses activated battery, accusing the LG to use an old technology, 35 years old, and delivers only half the potential resolution and high definition (1080) of motion pictures. 

In fact, the LG uses images of 540 pixels per eye. The company claims, however, that the sum of these two brain images of 540 pixels to produce an image of 1080 pixels with the same pattern of high-definition Blu-ray disc. 

In the war between the two corporations, Samsung has recently promoted a campaign in South Korea, with a print ad that attacks the Cinema 3D TV technology. A high-level executive from Samsung, LG engineers accused of "stupid". But later apologized. 

In this war, LG Samsung has challenged the public for demonstrations of both systems before independent researchers and journalists. Samsung has so far not accepted the challenge. 

Faced with complaints from customers, Samsung says it is creating new glasses, more comfortable, giving two pairs still free to buy any model and only charging $ 50 per extra glasses. 


Film and TV are the result of an optical illusion. With the rapid succession of images, like in the movies or on TV, the 25 or 30 frames per second, our brain fuses the images fast and gives the perfect sense of motion pictures. 

A similar, but slightly more complex case with 3D TV technology, which uses an interesting trick to fool our brain: the left eye shows a right eye image and the other. The brain superimposes these images to produce the visual sensation of three dimensions. For films of the latest 3D movie glasses, polarized light filter the different images for each eye. 

3D TV technology in active glasses use batteries to power the lenses that open and close the lens in a synchronized manner so that each eye see a different picture. 

In real life, the sense of 3D requires that our eyes do two things. First, they need to move slightly inward or outward so that the projection of an image is always focused in the center of both retinas. Second, our eyes must converge and accommodate - changing the shape of each lens to focus the image on the retina. 

Martin Banks, professor of optometry at UC Berkeley, who researches the effects of TV and film in 3D human visual system, "without adequate convergence, you end up seeing double images or blurred images."
