Companies such as the East European brand XpanD have announced plans to bring such glasses to the market soon. Even with these, an additional syncing device may be required in some cases.
Active shutter 3D systems are used to present 3D films in some theaters, and they can be used to present 3D images on CRT, plasma, LCD, projectors and other types of video displays. Yeah, definitely. Any DLP glasses will work. Movie theaters typically use RealD 3D glasses, which are passive 3D glasses and these will absolutely work with your 3D system at home, providing it also supports passive 3D technology. While active 3D technology is the most common type, movie theater glasses will work in your home if you have a passive system.
Active 3D uses battery-operated shutter glasses that do as their name describes: they rapidly shutter open and closed. Passive uses inexpensive polarized glasses, like what you get at most movie theaters. The TV has a special filter that polarizes each line of pixels. While one lens filters out all the red in an image, the other lense filters out the cyan, causing your brain to see the picture in 3D.
How 3D glasses work when it comes to polarized lenses depends on deceiving your eyes just like anaglyph glasses do. How do polarized 3D glasses work, you ask? They restrict the light that enters your eyes, but instead of restricting the light by red and blue colors, they have a yellowish brown tint. The image on the screen also has a role to play.
In addition to the polarization on the glasses, the projected image is actually two images that are superimposed on the same screen through a orthogonal polarizing filter. Then the glasses, which have the same type of filter, allow each eye to see a the two individual images on the screen.
Shutter glasses are considered the most advanced type of 3D glasses available today. In this system, two images are displayed on the screen, one in red and the other in blue or green. The filters on the glasses allow only one image to enter each eye, and your brain does the rest.
You cannot really have a color movie when you are using color to provide the separation, so the image quality is not nearly as good as with the polarized system. At Disney World , Universal Studios and other 3-D venues, the preferred method uses polarized lenses because they allow color viewing. Two synchronized projectors project two respective views onto the screen, each with a different polarization. The glasses allow only one of the images into each eye because they contain lenses with different polarization.
There are some more complicated systems as well, but because they are expensive they are not as widely used.
