1. What is the primary technologies?Utilizes stereoscopic display, active shutter systems, and polarized 3D systems
2. What is the autostereoscopic capability?Some systems offer 3D viewing without the necessity of wearing special glasses
3. How do 3D TVs make pictures look like they pop out?The TV shows two very similar pictures at the same time, one for each eye, and the glasses or screen tricks your brain into combining them into a single 3‑dimensional image.
4. Why do you need special glasses to watch 3D TV?The glasses have tiny lenses or filters that let only one eye see one picture and the other eye see the second picture, so the brain can create depth.

Stereopsis: The perception of depth and three-dimensional form produced by binocular vision.
Active Shutter System: A 3D display method where electronic shutters in glasses synchronize with the TV to alternate images for each eye.
Polarized 3D System: A technology that uses polarized filters in glasses and on the screen to direct different images to each eye.
Autostereoscopic Display: A display that can produce a 3D effect without requiring viewers to wear any special eyewear.
