The categories of 3D stereo galsses and the ways for selection

Many people may want to buy a pair of 3D glasses to have a wonderful experience. But some of them do not learn too much about the stereo theory and easy to misunderstand. Now I will tell you their categories for you buy at ease. There are 6 kinds of 3D glasses: time-division type, complementary, polarization, raster, identical, viewing and hologram. Now I will pick out some to discuss in details.

Time-division type: it is mainly LCD glasses, they have excellent vision, if the screen is big enough that the vision will be as same as in the movie. For computer game fans, it is a nice pair of 3d glasses. however, the shortcoming is that you need a CRT monitor.

Complementary type: it is only red/blue, red/green 3d glasses. the price is very cheap just cost you several dollars. And it has no special need for screen and can be used in TV and projector. The shortcoming is that there are double images. But this method is very popular in the foreign countries. And you can wear it too long because it will hurt your eyes, therefore, when foreigners watch movies, there is a 2D snippet.

Polarized 3D glasses: this one is only used in theatre not at home. But if you have a double-projector at home, you can use it of course. But it is too expensive, not realistic. So it is useless to buy a pair of polarized 3d glasses for using at home except you buy a 50,000 yuan double-projector equipment. Or wait for a new double-screen LCD monitor in the future.

Raster 3D glasses: this one was created in our country in order to celebrate the Olympic Games in 2008. The shortcoming is that the images are not clear enough and you need a very big TV.

If you want to know more about the 3d glasses, you can go to Wikipedia there will be more information. If you want to buy a pair of 3D glasses, you can buy it from the market or the online store. Now you can choose anyone you like according to the information I tell you. Hope you can find a nice one!
