Does The Future of 3D TV Lies in Passive Tech?

There has not been much to cheer about so far as 3D TV goes for the year just gone by. The lack of suitable content has been adjudged the usual culprit by experts in this field for this dump of interest, though that’s not all for there is also the technology factor involved as well. Or to be precise, it is the active vs. passive tech that also can be considered to have taken its toll. A shift to passive technology it appears would help in stemming this downwards graph of the 3D TV popularity chart.

There is a noticeable shift towards the passive technology which even big names that had started on active technology are also moving towards. The active TV technology then had the aspect of profit due its less time taken to reach the market, though the advantage seems to be over as TV sets based on passive technology appears to be taking over. Sony has been the last big names to move to passive technology and that gives customers more options to select from.

A prime factor against active viewing glasses is that they cost quite an amount given the technology that goes into it. Even though manufacturers have been giving out the glasses within the price of the TV set, yet the solution is not working out in favor of the consumer. There are broadcasting companies also who offer the glasses as part of their subscription offers. Consumers feel the bundled price tag itself is quite high and does include the cost of the viewing glasses.

Another reason why 3D viewing glasses that are required in active 3D technology is the discomfort they cause. It is heavy, for there is quite some technology that the glass packs in itself including the battery pack. For these reason consumers prefers the glassless viewing experience.

Glasses that have to be worn in case of the passive 3D TV sets are comfortable and also cheaper. There is another big advantage that these glasses have over active and that is its compatibility across different brands of 3D TV sets working on passive technology. There are movie halls also that one can use these glasses in.

Active 3D technology requires the viewing glasses to close and open and very high intervals. This however causes flicker effect on some people whose eyesight is not suited for low refresh rates. This effect does not exist in case of passive technology and the viewing glasses thereon. There are many reasons therefore for the technology to go the passive way for 3D format to work in case of home entertainment through TV programs.

There is also the fact that content would naturally improve and increase with the induction of the passive technology as mainstream. The products would be affordable and the viewing experience would be much better.
