Looking ahead to 3D
Seems to me that Passive has no choice but to win out over the competing formats "active" or "freeviewing" IF 3D is going to be a widely adopted format for all displays.
By widely adapted I mean for a significant amount of broadcasts (primetime, movies, and sports). That being the case, advertising, internet and anything that can be displayed could follow.
Imagine a world where you go to a mall and 3D signs and advertising grab your attention. Imagine driving down the road and billboards and signs provide added depth. Imagine web content delivered in 3D. Imagine going to a sports bar and a good portion of the TV's are broadcasting 3D sports.
Obviously a lot has to happen for 3d to be that widely used, but it could also be as simple as your house being 3D'affied with your TV and your computer (and possibly your phone and your watch).
OK, you get the point. Multiple sources, multiple signals and different manufacturers.
I'll go one step further. The adopted 3D format for the future will be Passive where the polarized light is circular. It is the only format that allows for viewing of multiple sources at multiple angles.
Active 3D will stifle the growth of 3D, consider it the beta max of 3D (superior technically but functionally inferior). It's not practical and not possible to view multiple sources at one time outside of a controlled environment. Walk into a sports bar and your active glasses will most likely not sync because of different manufacturers, multiple signals and Doppler effect (I'm not sure about Doppler effect at the speed of light at these distances though, but it's a thought).
Freeviewing? Well, if you look into it, then you'll realize that anything over 1 source isn't feasible.
Why circular? Because it accounts for head tilt and off-angle viewing while linear does not.
Just some thoughts. But I might be purchasing stock in Real3D soon.
