Comments on: Best 3D Glasses – Passive Polarized vs Active Shutter 3D technology

There is NO ghosting at all with passive sets (compared to active anyway). Ghosting normally means the image from one eye bleeds into the other eye (more correctly referred to as cross-talk).

As circular polarizing technology is used this means you can tilt your head quite a bit (the image will become 2D at 90° though)

Considering comments I resigned from buying active 3d LG TV set. But before I buy a little bit more expensive LG passive 3d I would ask if any of you can tell me what happens if you tilt your head? What is all that talking about ghosting – what does it mean?!
Thanks

To me the advantages of passive over active is overwhelming – and not just in theory but in practice too.

Due to pricing I started with an active system (which to be fair IS impressive on first use) but once you then move to a passive system then the superiority at every level become apparent. That’s probably not the best way to buy a 3D TV but it does at least prove the grass is sometimes greener on the other side!

I bought the LG 47LD950 which by the way is also excellent for spectacle wearers as the circular polarized glasses supplied easily fit over the top (you can buy 3rd party glasses anyway or simply visit your local cinema for extra pairs)

I wear eyeglasses and am having trouble finding any info on which 3D glasses work better with eyeglasses. I’m thinking about getting a Panasonic 3D plasma.

also, the difference in contrast (brightness increase needed) between active and passive glasses should be mentioned.

The article should mention that circularly polarized glasses exhibit greater ghosting than shutter solutions, especially in high-contrast situations, because circular polarization filter does not block the light completely (getting rid of ANY ghosting??).
In case of linear polarisation, this is way better (3x), but you cannot tilt your head to not break the effect – another disadvantage.

Hi there,

Sorry for the confusion. Actually there isn’t any contradiction. The first line you quoted about muted colors, etc. is with regards to old anaglyph glasses technology (which is also a form of passive 3D). The advantages listed later on are with regards to passive polarized glasses, which are different from anaglyph glasses and are very good solutions for providing a good 3D stereoscopic image to the viewer.

I think the article is self-contradictory. First it says of passive 3D that

“the muted colors lead to a very surreal, uncomfortable and visually jarring 3D experience”, then it says:

Advantages of Passive Polarized 3D Glasses
* Provides amazing visuals and very rich colors

I want to agree with Edison Birth. I have not purchased a 3d set yet as I have been sold on passive glasses. The flashing motion in the active glasses gives me a headache, whereas the passive technology does not. Ironically the passive vs active subject is the exact reason I stumbled onto this site in the first place. I have yet to find anyone truly do a professional side by side comparison of the technologies. All the articles I have found are written from a secondhand standpoint. Meaning they state what the “industry facts” are… but clearly haven’t compared the performance of the technologies. Currently LG is selling a complete line of passive 3d models in the UK. Other than that, JVC has a single professional model. I want more hard info on the REAL….TESTED differences. I have seen the passive JVC (very briefly, once) and the 3d performance was outstanding. I have also seen numerous active setups and all had crossover and ghosting caused by missed lcd flashing and all also gave me eye strain…….I’ll be waiting for more info on passive glasses technology……..

Ed, your 3D TV guide is excellent; thank you very much for providing us, consumers, with your unbiased technical expertise and comments. However, you should consider revising/updating your guide and verdict on active versus passive glasses for 3D TVs. In my opinion, Active Shutter based 3D TVs, should no longer be recommended, despite the big push by the major 3D TV manufacturers in that direction.
Reason: on May 28, 2010, a new 47-inch TFT LCD flat panel 3D TV was introduced at the Society for Information Display (SID) trade show in Seattle. This 3D TV set works with very inexpensive passive polarized glasses, which are free from flicker and crosstalk, and therefore, they do not cause dizziness, eye tiredness and headaches, as the active shutter 3D glasses do.
Therefore, I have decided to postpone buying my 3D TV set until I can get one of those with passive circular polarized glasses in the stores.
