What Riddhi Patel said is very true the 3D TV sets are there but there is lack of 3D content, only the movies are at present available for 3D viewing. And the viewing using the glasses is also cumbersome while watching TV and trying to get relaxed.
Currently, 3DTV still does not serve up the picture in a natural way, e.g. how most people would actually view a particular scene in the real world. There would have a much finer graduation in depth perception for that to happen. But you cannot argue that the attempts being made to provide a commercially acceptable 3D visual experience have come a long way. A glass-less version is close to the Holy Grail.
No glasses 3DTV won't come in the coming 3-5 years. The current 3DTV has already made a big lap. Sony has improved its 3DTV in the last 1.5 years. The quality has improved substantially and I can hardly notice any difference regardless of viewing angle. I assume the other major supplier such as Samsung makes a good advancement too. With the current trend and supplies, I believe the price of glasses will come down significantly in a year, definitely before a No-Glasses-3DTV becomes popular.
Lots of people were doubting that HDTV would ever take off, in its early days, and yet I had absolutely no doubts that it would. I couldn't believe that people would prefer to continue watching the ugliness of low-def analogue, as soon as they experienced what TV should be like, and as soon as the sets became affordable.
This 3DTV slow uptake could be seen in the same light. And yet, here I am much more skeptical. The occasional, and I stress occasional, 3D movie might be fun. I doubt people would want that experience as a steady diet.
Anything to hang on to margin... If and when my tv bites the dust, I will undoubtedly want to buy one that is 3d capable... As long as it doesn't cost me anything in picture quality and measureable cost.
