Is their really any kind of generations in TV?s also?
3D TV is fairly new, the technology really only growing in the last 1-2 years ( assuming you discount the old anaglyph technology that never really worked).
So it's difficult to talk in terms of generations.
The first 3D TVs were based on active shutter glasses technology ( refers to the way the glasses work with the TV). They are still on sale and work well...but the glasses are a problem...uncomfortable for some people, expensive, and only work (in most cases) with the manufacturers set that you bought. Even so, plenty have been sold.
There are recent models which work with passive glasses. Lighter, cheaper, similar to those you get at the cinema.
You could say they are the two generations, existing side by side.
When no glasses 3D TV is fully available that'll most likely be the third, though perhaps that could be eclipsed by mobile 3D TV.
TV technology gets better all of the time and new models are released around the time of the next business year, and I think at this stage, it is still too early to delve into the world of 3D TV.
Some TV manufacturers are opting to change the infrared system to Bluetooth. Not only will this improve battery life, but also they say it will reduce 'crosstalk' (which plagued most first gen 3D tv sets).
Not enough content available in 3D either. 3D tvs were out long before the first 3D Blu-ray players and discs came about.
In addition, many manufacturers are changing the way they measure refresh rate. Instead of it being quoted Hz (Hertz), For example Samsung now calls it CMR, and Sony calls it XR. So this years 3D tvs should also have better motion whether you're watching 3D or if you watching a 3D TV in ordinary 2D mode.
