3D is based on the principle of stereoscopy, which creates the illusion of depth in an image. There are currently three kinds of 3D technology on the market and each one works differently. Let’s learn more about each of these technologies.
There are currently three kinds of 3D technology on the market and each one works differently:
The first one, anaglyph technology, is the most famous one (think red/blue paper glasses) but usually the 3D effects are not so great.
The second one, polarized (or passive) technology, is the technology you have been exposed to when watching a 3D movie in an IMAX theater (e.g. Avatar 3D, Alice in Wonderland 3D, etc.). Now some brands are using this Technology in new 3D HDTVs as well.
The third one, active technology, is the most recent technology that was used in all the first generation of 3D HDTVs that came out in 2010. This is still a popular approach to 3D HDTV and despite the introduction of passive 3D technology in HDTVs this year, active technology is still the only approach used by a number of the biggest TV brands.
