What are passive 3D TVs?

Passive 3D TVs are three -dimensional TVs that use passive glasses that rely on different light waves rather than rely on battery energy. Glasses used with passive 3D TVs are polarized in a specific way to block different forms of light for each eye and create depth illusion. This is an alternative to active 3D TVs, but may be a problem for people who have trouble perceiving depth. Both passive TVs and passive glasses are cheaper than active forms and glasses are much lighter than active 3D glasses that require batteries.

To create the illusion of depth and achieve 3D image, each eye must be presented with a different image. The eye must not only see another image, but both must see both with each eye at once, causing the brain to combine images and create a deep illusion. With passive 3D glasses, a special polarization process similar to the process made with sunglasses is careful. The difference is that the sunThe glasses muted all forms of light, while passive 3D glasses dampen different colors and forms of light for each eye, causing each eye to perceive the image differently.

Passive 3D TVs are those that use these passive glasses. Usually there is a possibility to change between two -dimensional (2D) and 3D watching, because some people may want to limit their exposure to 3D or would rather see a specific movie or show in 2D. Unlike active 3D TVs that have infrared devices that interact with glasses, it does not include passive 3D TVs. Passive glasses can also be used with any passive TV, regardless of the brand or model.

There are some problems with passive 3D TVs, especially for passive technology. Movies and programs are sometimes blurred or do not appear 3D because glasses are made to work generally and can interpret with incorrectlybranch. The 3D effect can also be displayed only from certain angles, so users must sit directly in front of the TV to achieve full effect. Concentrating on specific places on the screen can also cause eye irritation, but this applies to both active and passive 3D glasses.

While there are some compromises in image quality with passive 3D TVs, there are also benefits. The biggest price is because television and glasses are much cheaper than their active counterparts. Goggles do not use batteries, so the chargers are not needed. Goggles are also much lighter, which helps users to relax in using glasses.
