How Do Plastic 3D Glasses Work?

How Do Plastic 3D Glasses Work? Both the lenses of the 3D glasses and the images on the screen are polarized. This restricts the amount of light that is able to enter your eyes. On screen, there are actually two separate images close to each other. Each eye sees one of the images through lenses with similar polarization to those that are on the screen. This causes the brain to merge the images that you’re seeing through each eye into one 3D image. No matter what type of 3D glasses you use, deceiving the brain to see 3D content is...

What is the difference between active shutter glasses and passive polarized 3D glasses? Active Shutter Glasses: This technology has been adopted by most consumer electronics firms like LG, Samsung, Panasonic, etc. With this technology, an HDTV will display one image to your left eye and one image to your right eye. Since the effective frame rate is halved, these HDTVs need to have double the refresh rate of HDTVs (60 Hz).

How can you get 3D from a 2D screen?

The two full-size images occupy the entire screen and appear intermixed with one another–objects in one image are often repeated or skewed slightly to the left (or right) of corresponding objects in the other–when viewed without the aid of special 3D glasses. When viewers don the glasses, they can perceive these two images as a single 3D image.
