What are the main types of 3D glasses?

Leading Word: In order to allow more people to walk into 3D theaters and enjoy the shocking effects brought by 3D visual feast, 3D glasses constantly improve themselves. While tending to be portable, they clearly use classification to subdivide theaters, TVs, and business presentations. The types of eyes, but also for different age stages of vision development adjustments in order to better meet market demand. What are the different types of 3D glasses? I believe that most people do not know, then this article will be popularized for everyone.

Basically, there are three categories of 3D glasses, namely: polarizers, red and green films, and red and blue films.

Red and blue 3D glasses: The principle of using color paper to filter color light: Each side filters out the red or blue color cast to leave the picture that should be seen by the eye. In this way, the color of the film is difficult to grasp and the effect is not good, so now it is very Less used, more films.

Polarized lenses: Two polarized lenses, two incompletely overlapping images, and a normal 2D image when viewed separately.

LCD shutter glasses: sounds very complicated, in fact, the principle is very simple, is the left eye of the figure to the left eye, the right eye of the right eye. When the 3D movie is played, the same polarized video on the screen is two images, but the two images are alternately and rapidly blinking. When the A-chart appears, the B-form disappears, and the B-form A-pattern disappears. At the same time, the LCD shutter glasses will follow the signal given by the video, corresponding to the corresponding AB chart to perform the synchronous and alternating lens switch action. When the actual use, the image and glasses shutter flashing switch will be very fast, the human eye can not feel the shutter beat of. This technique works well, but the equipment is expensive and there are some restrictions on use. Long-term viewing can cause eye fatigue, the signal is vulnerable to interference, and electricity is also needed.
