3D blu ray needs to be passive polarized  

I have seen technology from videogame manufacturers that looked cool but they lost their fun factor quickly and were clunky and expensive.

I can see people looking at 3D active polarized glasses as a gimmick. They say that it is too expensive and they need to buy a lot of them, and not everybody will be sober when wearing them and they are battery powered delicate electronic devices.

I see the active polarized glasses won't work on every manufacturers 3D tv. So this really really adds the gimmick factor.
It's the glasses that will make 3D a poor sad failure as the oem's want active polarized so the tv's don't cost so much and they can pass the cost onto the glasses.

What 3D blu ray needs is passive polarized glasses so they are cheap.
Then it's easy to buy new glasses when the kids or your drunk friends watching tv ruin the glasses. Somebody's gonna step on them or poke a hole in them or rip them and it would be easy to buy a new pair for 8.00 or so.

If there is ANY way to stop panasonic and other oem's from going exclusively active polarized then Right Now they should go to passive polarized.
At least be agnostice between active and passive so the customer can choose and make the money show what we want.

Old fashioned forward thinking old people will watch in 3D if the glasses don't cost a lot of money. But if the glasses cost a lot of money they will reserve it for their kids kids.

In the case of RealD a circularly polarizing liquid crystal filter which can switch polarity many times per second is placed on front of the projector lens. Only one projector is needed, as the left and right eye images are displayed alternately.

So this is frame sequential, hence pdp/lcd compatible.

Seeing is believing. Until a calibrated system is demoed for critcal reviewers I can't say if the glasses being inexpensive is bad or not.

passive polarized 3D can be frame sequential full resolution per eye:

"The Sony 3D lens adapter maximizes the exclusive technology of the 4K SXRD® imaging device, which displays four times as many pixels as conventional 2K projectors for digital cinema. This allows full 2K resolution for the left and right eye simultaneously, resulting in a high-luminance, full-resolution stereoscopic cinema presentation and is designed to enable more faithful reproduction of motion in 3D."

Reading that article from the sony website it states:
"conventional 2K projectors for digital cinema" is replaced by a 4k projector.
"This allows full 2K resolution for the left and right eye simultaneously, resulting in a high-luminance, full-resolution stereoscopic cinema presentation and is designed to enable more faithful reproduction of motion in 3D."

So passive polarized glasses can be full 1080p if the resolution of the monitor is twice that of 1080p. So the only glasses available this year and for many years is for 1080p tv's, meaning only active polarization glasses will be blu ray 3D compatible.

So those companies selling 3D tv's intending to use passive polarized glasses won't meet the 3D specification the bd association made late last year. Unless those tv's are twice the resolution of 1080p.

If a family went to one of these 4K real D 3d movies using passive glasses and think 3D tv uses the same technology, they will be surprised to see the new tv's use active technology in the glasses, not passive.
