Ditto, explain why. Thank you. Try to be more careful.
this is a polarizing film 3D common solutions, the so-called principle of polarization in the cinema, and in fact some camera lens polarizing or sunglasses almost. It can be divided into two types: linear polarization and circular polarization. The linear polarization is relatively simple, using XY two orientations, namely through the polarizing lens two glasses on different deflection directions, respectively, let two eyes can only see a vertical and horizontal image superimposed on the screen, to see stereo effect. Circular polarization is a new generation of 3D polarization technology, optical technology is much more complex than the XY polarization of the thin plastic film;
Charged with the kind of "shutter" ordinary kind of call "polarized" detailed I copy to you shutter glasses sounds very complex, in fact, the principle is very simple, is the left eye diagram of the left eye, right eye diagram of the right eye to see. 3D video playback, the screen is the same as the polarization film is two images, but these two images are alternately fast flashing, A figure appears B map disappears, B figure appears A disappear. At the same time, liquid crystal shutter glasses will be in accordance with the signal film to the lens switch synchronization alternately corresponding to the AB two, the actual use of flickering switch when the shutter and image glasses will soon, the eye is not feel the beating of the shutter. This technique works well, but the equipment is expensive, and there are some restrictions on the use of a long time to watch will lead to eye fatigue, the signal is also vulnerable to interference, but also the need for electricity
As the name suggests, it is a circular polarization of the lens rotation, a rotation to the left, a right rotation, so that two different directions of the image will be separated. This polarization allows it to basically achieve a full range of 3D, not like the XY line polarization must maintain the level of glasses / vertical angle. Because the main use of the lens deflection of light, it is also known as: "light" technology
