About 3D Projectors
3D Projectors are one natural trajectory for the projector technology in the near future. “3D Ready” means that the projector, with the right 3D conent, and accessories, can produce two virtually simultaneous images essential for the 3D image viewing model. Then, thanks to active or passive glasses, deliver those two image streams, one to each of your eyes.
As of the end of 2010, the amount of 3D content remained rather limited. Other than the gaming world, where PC gamers can convert many 2D games to 3D games, on the fly, with the right graphics cards, such as some Nvidia display card models, it’s downright sparse. Few movies exist in 3D, though those are well known. in late 2010, there were few 3D movies, and most under temporary license only to one manufacturer, not much to buy. Not so, a year later, as my 3D movie collection is now in the dozens, and there’s lots more 3D contetn – 3D movie, 3D sports, and lots of Discovery HD type content in 3D, to be found on cable and satellite
3D Projectors that use single chip technology, such as those single chip DLP projectors that are 3D Ready, work with those expensive active LCD shutter glasses. Today almost all 3D projectors for your home, schools and business are using active shutter glasses.
Each technology has distinct advantages, but in the US, active glasses are dominating, the high cost of glasses offset by much lower cost projectors, than those that can use passive glasses.
Starting the fall of 2011 3D projectors for home should start growing signficantly in market share, prices are far lower than a year ago. Highly specialized 3D solutions for business will gain wider usage, still mostly on a specialty basis – that is – used sparingly and only where truly worth the early costs – such as, perhaps displays of 3D modeling of brain scans, or a command and control facility at the EPA monitoring drilling in the Gulf.

A benefit of 3D projectors using active glasses, is they can work on almost all projector screens. Those (at least for the moment) using passive glasses, really must have a screen that is optimized for 3D. I should note that does cover some traditional (but usually expensive) 2D screens, like Screen Innovations Black Diamond screens, but also there’s a whole new crop of 3D screens from Stewart Filmscreen, Da-lite, and most other players in projector screen space.
If you are a home theater person, you should keep this in mind, at all times: 3D can be awesome with good content. I’ve been watching 3D content on screens up to 100″ and I’ve watched 3D on 40 and 50 inch LCDTVs. With projectors – it’s like the theaters – awesome – you are immersed. With those LCDTVs, it’s like having a cute little window box in 3D. “awe – how cute” but forget the immersive 3D “theater” experience. Tsk!
If there’s one area where projectors blow away smaller displays, more than any other, it’s got to be 3D. People who have been in my rooms and seen some of the 3D content on a large screen – are – truly impressed!
