What glasses should I use for a 3D movie with two pictures combined?

3D glasses adopt the most advanced "time division method" at present, which is realized by signal synchronization between 3D glasses and display. When the display outputs a left-eye image, the left-eye lens is in a light-transmitting state and the right-eye lens is in a light-transmitting state, while when the display outputs a right-eye image, the right-eye lens is light-transmitting and the left-eye lens is not light-transmitting, so that two glasses can see different game pictures and achieve the purpose of deceiving eyes.

Types of 3D glasses

1, complementary color

Also known as chromatic aberration, 3D glasses with colored lenses such as red, blue, red and green are common.

Color difference can be called color separation stereo imaging technology. Two images taken from different perspectives are printed in the same picture in two different colors. If you look at it with the naked eye, it will show a vague ghost. Only through the corresponding red and blue stereoscopic glasses can we see the stereoscopic effect, that is, filter the red and blue colors. The red image passes through the red lens and the blue lens, and the different images seen by the two eyes overlap in the brain, showing a 3D stereoscopic effect.

2. Polarization

Polarized 3D technology is now widely used in commercial cinemas and other high-end applications. The technology mode is the same as the shutter mode, but the difference is passive reception, so it is also called passive 3D technology. The cost of auxiliary equipment is low, but it requires high output equipment, which is very suitable for commercial theaters and other places that need a large audience. Non-flash type uses this principle.
