Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. As of 2017 [update] , most 3D TV sets and services are no longer available from manufacturers.
Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D".
A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters .
Toshiba (TOSBF) unveiled a new 3-D TV that viewers can watch without wearing special glasses. The 3-D liquid crystal display TV uses a high-definition screen backlit with LEDs, a special sheet on ...
Watching glasses-free 3D on a TV is no longer an outlandish concept, but that hasn't been true for movie theaters. ... And unlike previous attempts at large-scale glasses-free 3D, you don't have ...
A pair of CrystalEyes shutter glasses Functional principle of active shutter 3D systems. An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images.
The SG technology can only use glasses which are connected with TV in sync so there are few glasses that viewers can use. In contrast, the FPR technology does not need this process so there is no limit to the number of people who can watch the 3D TV at the same time. In addition, glasses can be shared between different 3D sources, including ...
While over 40 million 3D televisions were sold in 2012 (including systems that required glasses), [63] by 2016 3D content became rare and manufacturers had stopped producing 3D TV sets. While the need to wear glasses for the more affordable systems seemed to have been a letdown for customers, affordable autostereoscopic televisions were seen as ...
