Our Circular Polarized Passive 3D Glasses Work With All Circular Polarized Equipped 3D Systems

Circular Polarized Passive 3D Glasses

The recent launch of our Circular Polarized Passive 3D Glasses on the market has let people enjoy a high-quality 3D cinematographic experience, regardless of the brand of their TV. The main aim is to provide our customers a 3-dimensional viewing experience while watching movies, documentaries and music videos at home.

Circular Polarized Passive 3D Glasses

All passive 3D TV’s have a circular polarized system, as well as the RealD 3D system present in almost all movie theaters. The passive 3D systems use a simple technology. The TV or projector emits the signal clockwise and counter-clockwise, and the way the glasses are polarized, allows the viewer to see the different image with each eye at the same time. So basically the lenses work as a filter, tricking the brain into translating the two different images into one image with depth, a 3D picture. The big advantage here is that the 3D glasses don’t do any active processing (hence the name passive), so they also don’t need any batteries. 3D glasses for active systems need batteries and are heavier to wear. More about active systems later on this blog.

As all Passive 3D TV’s and REALD 3D movie theaters use this same circular polarized technology, the 3D glasses work with all brands of passive 3D-equipped TV sets as well as REALD theaters.

Linear Polarized Passive 3D Glasses

Before circular polarized systems were widely used, there was another polarized system: linear polarized systems. In this case the projector emits one light signal horizontally and the other vertically, so with a 90 degree angle between the two images. Again, the polarized 3D glasses work as a filter: one lens filters out the horizontal image, where as the other filters out the vertical image. Together creating one picture with depth. IMAX theaters still use this technology, hence it is important to know that these two kinds of passive 3D glasses cannot be interchanged.
