The general principles are the same as for the anaglyphic 3D format as two slightly different images are seen by each eye, assembled by the brain into one image creating a sense of depth. The way of achieving this though is very different. These glasses work by allowing each eye to see differently polarised light.
For example, light polarised in one direction will be seen by the left eye and light polarised in the other by the right. The frame sequential format is already the accepted standard for 3D Blu-ray. The active shutter glasses are synchronised with the television through an infra-red signal and rapidly blink on and off to play to back images alternatively to the viewers eyes at a rate of 50 frames per second.
These glasses are typically designed to be brand specific although Panasonic and Samsung are interchangeable. These glasses are primarily designed for watching 3D Blu-ray content. These glasses are also quite a lot more expensive and require a power source to drive the LCD shutters, usually via a USB port on the television. Some viewers have complained of warm eyes after prolonged use from these early models.
Such technology is refered to as auto-stereoscopic. Philips has led development of this format but a commercial version is said to be more than five years away. Follow Us. DisplaySearch forecasts that 3D TV shipments will balloon from 0. The revolution will be televised. And those with the biggest wallets will enjoy it in 3D. All of which suggests that the term '3D Ready' is just a catch-all phrase for a less exciting but more accurate one — 3D-capable.
The fact that passive isn't available on plasma TVs is also an issue to home-theater enthusiasts who don't want to buy an LCD. We prefer the 3D picture quality of the best active 3D TVs over passive for critical viewing Our main hangup with passive 3D TV is the presence of the artifacts mentioned above, which we find especially distracting at the closer seating distances and with the large screen sizes favored by home-theater enthusiasts.
But with the practical and certain picture quality strengths of passive 3D, especially in bright rooms, an argument can certainly be made that it's the better choice overall. Check out "Active 3D vs. That's what 4K TVs that employ passive 3D promise. Their higher resolution should eliminate most of those jagged edges and line structure.
You need made-in-3D source material to take full advantage of a 3D TV. Many 3D products feature 2D-to-3D conversion options, but they're a far cry from a real 3D source. The ratios are comparable, and so far in 3D Blu-ray releases are on the same pace as the last two years.
In other words, 3D Blu-rays aren't getting much more common as the format matures. There are also quite a few blockbusters; nearly every big-budget 3D theatrical release also makes it to 3D Blu-ray.
The 3D Blu-ray format, and made-in-3D movies, definitely represent the state of the 3D art, with full high-def resolution and the benefit of the latest filming techniques to make the 3D effect comfortable and enjoyable. Unlike Blu-ray, 3D broadcasts on TV currently use a half-resolution 3D format known as side-by-side, resulting in a significantly softer, non-high-def look.
We know of no plans to add more 3D channels or introduce a full-HD resolution 3D broadcast. Click here for more on the differences between Blu-ray and broadcast 3D formats. The Vudu streaming service also has a smattering of 3D movies available. Sensio's 3DGo app , currently only available on Vizio TVs, promises more content than other comparable services. Games are often touted as the "killer app" for 3D TVs, but actual 3D games are still uncommon.
Today many popular titles are still 2D-only, and 3D games aren't really catching on fast. The Nintendo Wii does not offer 3D compatibility. The Wii U does, but no compatible 3D games are available yet. But lack of 3D content is a big reason people don't want to get a 3D TV today. We don't see this situation changing in the immediate future, and we feel glasses-free 3D TVs need to be available at mainstream prices -- and work well -- before 3D content has a chance to become as common as 2D high-def content is today.
How should 3D shape your TV buying decision? Not strongly, in our opinion. Here are few things to keep in mind. The best way to think about 3D is as 'just another feature' Manufacturers construct their product lines to get you to pay more for "step-up" features.
They're generally all tied together, too, which is why nearly all high-end TVs -- and many midrange ones -- now feature 3D compatibility. In our experience, the best-performing 2D TVs happen to have the 3D feature as well. If you're willing to pay extra for an improvement in 2D picture quality, chances are you'll be getting 3D whether you like it or not. That said, just because you buy a 3D TV -- even just to get the best 2D picture quality -- doesn't mean you need to ever use the 3D feature.
Don't buy a 3D TV just to stave off obsolescence If the only reason you're considering stepping up to the 3D feature is to avoid buyer's remorse in the next couple of years, in anticipation of 3D content becoming widespread, you should stick with a 2D TV. For reasons discussed in the content section, we don't see 3D as a "must-have" for most TV buyers, either now or in the near future.
