Let’s face it: everybody a little kids – even the most inveterate of us tough and – when the movies 3D surrounds us with its ghostly special effects. So natural that many came the idea that you can have in the comfort of your home something like that, and since the home 3D is a proven reality we see all to figure out what it is.
3D technology for TVs
The unique charm of 3D technology has captivated everyone, but certainly not everyone knows that there are several types to choose from before buying, and that sometimes the differences – that prices – are abysmal: Let’s start with the most common, i.e. those which require the presence of a pair of glasses.
There are two types of 3D technology with glasses: the active and the passive, both with their strengths and their weaknesses. Let’s start with the active: spectacles costing relatively little, are compatible with different brands and types of TV – non-trivial thing – weigh and clutter up shortly and also even after hours of use does not tire the view. The speech is rather different for the active 3D glasses, which have a number of very different characteristics, if not opposed in certain cases.
3D technology for TVs: which one to choose
Active 3D technology has in fact from his less defects like ghosting or cross talking compared to passive, but from a certain point of view the end user “pay the price”. What? First, directly in the store, because you have to pay to buy them a lot more than a couple of passive glasses. Also it is a thicker and much heavier and accessory that goes specifically synchronized with the TV, which also must be compatible.
The faster you pay also with a little eyestrain: better not to go beyond the 4-5 hours of continuous viewing transient penalty but pesky annoyances in the eyes. There’s no way so enjoy the 3D technology without these glasses a little uncomfortable?
In fact, you. Just recently the big companies are starting to get the first few markets TV models with built-in 3D technology and which does not require any type of accessory: How do they work exactly?
Basically don’t need glasses because you directly on your TV there is a kind of film can do da lens through which then our eyes perceive the magic of 3D. The cons of such a wonder?
There are and there are many. The first, is the price: for models currently on the market is called an outflow not less (roughly) to eight thousand euros. The second, is the surrender: we are still far from achieving a 3D even remotely comparable to the effects obtained in movie theaters and the road ahead in this sense will still take some time.
What is the active 3D in TVs
Let’s start by saying that in the present state of things, the vast majority of 3D TVs on the market it should be used in combo (combination) with special glasses: 3D TV without glasses are starting to look at but this is still a rather immature technology and, just between us, expensive.
Therefore when purchasing TV & glasses everyone is facing a classic choice. Making the decision to purchase a pair of glasses with passive 3D staandard-cheap, lightweight, very easy to use – or opt for the more modern and technologically active 3D avanzaro? In many choose the latter, let’s figure out together the pros and cons of this type of innovative accessory.
Active 3D, pros and cons
We can start with tell you that if you choose to bring a 3D active system will have to prepare psychologically to the fact that indeed is a bit more expensive. Good news is that it is compatible with all types of TVS currently on the market: LCD, LED, and also the most modern Plasma.
Active 3D technology provides that the glasses – who need their own separate power supply – are synchronized with the TV so that I can run that game alternating opening and closing image in the two eyes that, at the end, “tricking” your brain creates the 3D effect.
What’s left to say yet about the 3D active? We also observe some disadvantages, in addition to the price: the active 3D makes the pictures a bit darker than they actually are, and this for anyone who uses Plasma – by their nature can play better on black – it could be a problem.
And the hassle? In fact using goggle for several hours continuously active 3D type you encounter some eyestrain, fatigue than with passive glasses in fact does not manifest itself but, let’s be clear: any film lasts well below at 5 hours and beyond which are used to make this type of effects!
Continuing our series, we find also another small flaws of active 3D glasses: the footprint. In fact since their autonomy and their glasses with a chip inside inevitably don’t weigh very little.
Returning to the benefits of this technology, we can not forget the most hated ghosting and crosstalk: respectively the display of faded images and interference between the image intended for one eye and another image destined to the contralateral side. We are happy to tell you that these are two scourges that afflict more than anything else the users of passive 3D and it is very rare that these phenomena occur with those who use the other type of glasses.
