One of the most frequent arguments against buying a 3D TV is the
necessity of 3D glasses that go along with it. Most people consider wearing a
glass cumbersome, and will obviously not suffer wearing one. The active shutter
glasses further intensified the problem – with additional problems such as
crosstalk and flicker that left most 3D enthusiasts with a bad headache. This
problem was addressed to a large extent by the use of passive flicker free 3D
glasses that work in FPR based screens – such as those of LG 3D TVs.

However, the holy grail in 3D TV still remains a glass-less viewing
experience – when you can sit just across the TV, and watch in 3D without the
aid of glasses – cumbersome or not. Almost all major TV makers have been
investing considerable resources in making such a TV, since the first mover
advantages will be significantly rewarding in financial terms.
Contrary to popular perception glassless 3D viewing has already
been around for some time – it is only its application to 3D TVs that is proving
a challenge for makers. Nintendo was one of the first to add glassless 3D
viewing in its popular gaming consoles. Later, many prototype TVs from most of
the market leaders were displayed around the usual trade fair circuits – but
those screens were very small – while the customer preference is moving towards
larger TV screens all the time.
Over the recent past, a number of smartphone handsets have
incorporated glassless 3D viewing as one of the selling points – sometimes with
very credible and impressive results. A case in point is the LG Optimus 4X HD –
introduced in February 2012.
However, the biggest challenge, for TV makers, has been to adapt
glassless 3D viewing to larger screens. Recently, Toshiba announced a glassless
3D model, which will also be available in India – for a cool Rs 12 lakhs! But
in addition to its rather significant price, other issues will also prevent it
from achieving any semblance of success. To view the extra dimension on this
TV, you have to sit at very well defined angles, and at specified points. Any
deviation from this position and you will lose the 3D vision on TV, or worse,
see vertical lines on the screens – destroying the viewing experience.

Researchers are working at a number of innovative solutions to get
glass free 3D viewing – especially in TVs. A recent report
talked about a team of researchers in South Korea - engaged in developing a
technology that will generate 3D images off the screen itself. The screen will
wear the 3D glasses – so to speak!
At
present, glasses are still the best way to watch 3D TVs. If you are
uncomfortable with active shutter glasses, then you can definitely explore
passive 3D TV that uses passive flicker free 3D glasses. Passive glasses are
the way to go if you want light, comfortable and cheap 3D glasses, and the
attendant freedom that comes with it. LG 3D TV is one
of the leading TV brands in India that use the passive 3D technology, while
Samsung and Sony use the active 3D technology. Though 3D has caught up in a big
way in the west it is still a new concept in the Indian market though it is
slowly catching up. With events like the recently concluded London Olympics
broadcast in 3D the awareness and acceptance is increasing. And of course, can
anything compare to watching Avatar or Titanic in 3D in the comfort of your
home with a chilled beer and popcorn? I think not.
Glass free 3D is not a distant concept. But I haven't yet seen the trend of 3D TV's truly pick up amongst the masses owing to the high costs..
ReplyDeleteThe high cost is but one of the variables that determine the popular pick up of 3D TVs. A number of prospective buyers are more concerned about the attendant discomfort of wearing 3D glasses, or the lack of original 3D content. As and when these issues are addressed, more and more people will start buying 3D TV - and the costs will start coming down too with increased sales.
DeleteSome time before Glassless 3D is actually perfect
ReplyDeleteYes Rakshit, that seems to be the case at the moment. Thanks for commenting!
Delete3d Tv without glasses still long wary off. But Sony, LG and samsung good in 3d tv that they provide.
ReplyDeletetoshiba has 3d tv without glasses; but wary too expensive. saw video that lg has most patent for lte; may be they should get stuff going for glasses 3d tv as well.
ReplyDelete3d without glasses in the picture or photframe i can understand plus phones too; but a entire 3d tv with no glasses wearing; is that sc. fiction or real?
