Study finds passive 3D TVs superior to active | Crave – CNET

A new study comparing the two current types of 3D TVs available for sale, active and passive, finds that passive 3D TVs had superior image quality to their active counterparts. I was personally surprised by the finding, since Ive found the opposite in my reviews comparing the two types of 3D TVs.
The author of the study, Raymond Soneira, is the man behind the DisplayMate evaluation and calibration software. Ive found his past work generally on target and well-researched, with plenty of supporting labs-based observations. This study, encapsulated in an article called 3D TV Display Technology Shoot-Out, is in the same vein.
If youre at all interested in 3D TV or 3D imaging in general, the entire article is worth a read. Heres the main conclusion:
Based on our extensive lab measurements and visual test comparisons between 3D TVs with FPR Passive Glasses versus 3D TVs with Active Shutter Glasses, we found that the Passive Glasses TVs delivered substantially and demonstrably better all around 3D imaging, 3D Contrast and sense of 3D depth, better 3D sharpness, better overall 3D picture quality, immersion and realism, and freedom from 3D ghosting, image Crosstalk, and flicker. This was true in all but a small number of situations, all of which we document [in the report].
From the passive camp Soneira tested an LG 47LW6500 and a Vizio E3D470VX, while from the active camp he chose a Samsung UN46D7000 and a Sony KDL-46HX729. All are LCDs, and all but the Vizio use LED backlights. He did not test any plasma TVs but writes that “they all use Active Shutter Glasses that are virtually identical to the LCD models, so our conclusions regarding their flicker, comfort, convenience, and cost apply to them as well.
“The meat of the article is devoted to breaking down the observations and measurements of the various 3D picture quality factors, among them image brightness, flicker, crosstalk/ghosting both straight on and from various viewing angles, positions, and head tilts, resolution, and sharpness. In every category Soneira found passive superior to active, and he backs up his findings extensively with lab tests, charts, and precise descriptions of program material complete with time stamps. The idea is that interested parties can check the shoot-outs findings for themselves.

Viewers Choose Passive 3D Over Active 3D TV Sets
Viewers Choose Passive 3D Over Active 3D TV Sets
To many people, a 3D TV set is a 3D TV set. But it’s not, there are two distinct systems being sold right now. Active and passive 3DTV are fighting it out to win the 3D format crown, and LG have released data showing that passive 3D is preferred by viewers.
Passive 3D beats Active in consumer study
Passive 3D is found in most cinemas and uses circular polarization to separate the left and right eye images on screen. Active 3D needs a power source for the specs and each lens shuts to show each eye a different image.
Active 3D specs cost between $50-$100 per pair and require batteries. Passive glasses cost around $2 or just “borrow” a pair from your local theater.
There is much arguing over the systems, with proponents of active 3D claiming less flicker and a brighter image. Of course, passive users would argue with those points, and also mention the massive savings when needing additional glasses (some TV’s ship with one pair only!)

Active 3D vs. Passive 3D
Which 3D TV technology will come out on top? We put three 3D sets side by side to see which 3D tech is the right choice.

2010 was supposed to be the Year of the 3D TV. By now everyone was supposed to be watching everything from baseball to Grey’s Anatomy in three glorious dimensions. And it sounded great–until people discovered that the early active-shutter glasses were prohibitively expensive, and often hard to use for prolonged periods of time. The new wave of 3D TVs coming in from LG and Vizio, however, work with “passive” (polarized) 3D glasses, like the kind found in movie theaters, which are cheaper and easier to use–but sacrifice image quality. So we decided to set up three 3D sets–a Sharp LC-60LE835U active-shutter 3D set, an LG 47LW5600 passive 3D set, and a Vizio XVT3D650SV passive 3D set–side by side to see the differences for ourselves.

Plastic 3D Glasses
Plastic 3D Glasses technology is certainly here to stay and in a big way. Active shutter will be a big player as well in the 3D world. XpanD x103 is a brand of active shutter glasses that enables you to see 3D images on different brands of televisions and other devices like Blu-Ray DVD players and more.
The Xpan x103 active shutter, plastic 3D glasses will work on almost all new 3D-ready HDTV’s, no matter who manufactures them. The competition is already fierce, there are many electronic manufactures, like Samsung, Sony, Pioneer ect that are predicting that the market will become flooded with a need for the product in the near future with this cutting edge starting to become prevalent and affordable to the mass markets.

For 3D movies that may come to the home on a movie channel, these glasses are not provided. In these instances, 3D glasses must be made. If looking for comfort, simply use the alternative method to creating 3D glasses; its largest benefit is the ability to start out with a set of sunglasses or old glasses that feel comfortable and the method of creation itself does not limit one to a certain template like the first one does. This is a good method to use when looking to make a pair of 3D glasses that will feel a bit more comfortable than poster board or paper. Alternatively, these are easy to simply color over. If deciding to color over the lenses, use red and blue marker but nothing that is too opaque. Find a pair of comfortable sunglasses that nobody wants to use anymore. Plastic ones tend to be the best choice for this project since the lenses are pretty easy to pop out. Take the old lenses and trace around them with a marker on the plastic. This is to create new, clear lenses to replace the old ones. Cut them out either using scissors or using an x-actor knife. Also, regular plastic kitchen film will be needed. As long as it is plastic, firm enough to fit over the lenses yet
