3D TV - Do You Really Need It ?

One word For You ...Congratulations! You have just made the decision to buy a home theater system, or perhaps you have one already and are thinking of upgrading. One of your big decisions may be whether to buy a 3D television But do you really need one; and just what is there to watch in 3D anyway?

3D TV, or stereoscopic TV, is an effort at mimicking reality. It's an optical illusion, a trick to make our brains think something's got depth, when it hasn't - to make something look real, when it's not.That may sound a tad dishonest, but it's not different to adding extra detail with high definition cameras. 3D has broadly the same aim; though technically speaking it's completely different to HD.

3D technology is till relatively new, although several major television manufacturers are offering this option, including Mitsubishi, LG and Samsung. Other major electronics manufacturers, such as Sony, Panasonic and Philips have plans to offer 3D television this year or next. One advantage of waiting for 3D television is that, like most other types of new technology, the price will almost certainly go down over time.It is one of advantages for costumers

If you do invest in a 3D television, you still have to wear a special pair of glasses in order to get the effect, otherwise now any 3D TV without glasses. which some people, especially those who wear prescription glasses anyway, can find uncomfortable. The TV companies would like to be able to offer the feature without having to wear special glasses and it's simply a question of when this will happen.

If you aren't technologically minded, you may find it confusing that there are actually different types of 3D television available, although most experts consider so-called active shutter technology to be the best option. You still have to wear special glasses, although this option has the advantage that your existing system doesn't need to be significantly modified; it's also less expensive than other options.

However, you will need to replace the batteries in the glasses every so often with the active shutter system. This may be an issue if you watch a lot of TV or plan to invite a group of friends over to see your new toy. And of course, you don't want a dead battery in the middle of the big game.Although Now there are many manufacturers issued glasses without batteries and cheap but to more enjoy 3D TV technologically glasses with battery is more like by customers,

Before you rush out and buy a 3D television, you should be aware that there is not that much on at the moment to watch in three dimensions, although all that will probably change in the next year or two. Direct TV has just introduced three 3D channels and the sports channel ESPN is offering the 2010 World Cup and Now in Olympiade London 2012 we can enjoy this event with 4D Technology. And even if you are just watching in the standard two dimensions, some 3D televisions provide better picture quality anyway.

3D television is undoubtedly here to stay and three things are fairly certain: the quality of the product will improve, prices will go down and there will be more programming available. Whether you need to have 3D TV now is something only you can decide. Many people consider it gimmicky and the effect is wasted on talk shows and news programs. But there's no doubt that sporting events, travel shows and blockbuster movies can look better in three dimensions, rather than two. Let's to change from 2D to 3D technologically Television.

3D TV without glasses the next Technology

With the arrival of glasses-free - or auto-stereoscopic - gadgets like the Nintendo 3DS, 3D TVs are bound to follow suit.

Some pour scorn on the idea as a mass market, affordable product, but the broadcast TV industry wants it and such TVs do already exist in Japan.

But how do 3D TV without glasses work? Instead of glasses being used to differ the image seen by each eye, an auto-stereoscopic TV has a lenticular lens in its glass panel to do the job instead.

There are two catches. The first is that the lens cuts-down on resolution really quite massively, meaning that the actual 3D panel needs to have a '4k2k' resolution, which makes the loss of detail less crucial. A bigger issue (4k2k TVs are destined for mass production) is the number of 'views'. There are only so many 'corridors' or 3D 'sweet spots' on such screens, with a noticeable visual 'blip' between them; moving your head from side-to-side in front of an auto-stereoscopic 3D TV is headache inducing.

The challenge for TV engineers is to increase the number of views, and eliminate the gaps between each; the current form is nine views, with around 15 needed to make such TVs comfortable enough to watch.

Another factor is the viewing angle; the 3D effect is ruined outside of a 40-degree area in front of the screen, so there's no chance of a crowd gathering around to watch an auto-stereoscopic 3D TV.
