Passive divided into: red and blue polarized, linearly polarized light, circular polarized three types of 3D glasses. Let's look at the red and blue 3D glasses passive: it is the use of colored paper filter shade of principle, each side of the red or blue color cast filter out the rest of the eye should see the picture, color film in this way is difficult to master ineffective, so few people use, the film or more. Applicable display hardware: general two-dimensional display or for families Similarly, following several 3d glasses are in need of special equipment, or family not applicable. Now look at the linear polarized glasses: polarized 3D glasses, linear polarized direction scared degrees nine hundred and eighty degrees vertically and horizontally. Also for the 45/135-degree angle cross but it must be agreed between or else useless or LCD projector and glasses to use two projectors in order to have a three-dimensional effect is around about two rails images, polarized light must use a three-dimensional stereoscopic film special silver screen, the screen is generally not used, because they can not separate the two kinds of polarized light. Linear polarized stereoscopic system viewing angle, more like four to three on average about perspective mode but relatively small, because the viewers need glasses, but the cost may be low loss, more in line with operational efficiency, it is currently the most commonly used three-dimensional cinema mode. Movie more recently, the technology has matured a lot. Applicable display hardware: a liquid crystal projectors, digital projectors projectors can be. Have to use more than two in order to have a three-dimensional effect, you must use a three-dimensional special silver screen, the screen is generally not used, because they can not separate the two kinds of polarized light. Ring polarized glasses: polarized ring or circular polarized said, is horizontally staggered the odd and even horizontal light was left circularly polarized light counterclockwise left and right even lines in a clockwise direction for the right circularly polarized light, can be Ring type polarizer 2 projector and then through the playback quality unchanged (with the same linear polarized light), such as a liquid crystal retarder need to paste polarizing film on the LCD TV screen, but only one layer of a liquid crystal display to ring Characteristics polarizer pitching perspective is relatively small, about the relative perspective is wide, suitable for wide-screen and flat-screen projection space, the LCD display on the left and right vertical resolution of each image will be reduced by half. Its three-dimensional picture can still be accepted, chroma lightness are still above average, viewers need glasses, but the cost is low compared to many people watch together in line with the operating efficiency, the film more recently, the technology has matured. The other is the active shutter glasses. Shutter, it is powered off by the liquid crystal sheet can be transparent or dark principle to make available high-speed switching of glasses around, the film is projected with a projector or a single tip video player 120Hz LCD TV 120Hz high speed switching left and right eye images fashion show (such as 60 second grid, singular grid of the left, double the number of cells to the right eye, thanks to advances with 120Hz, the human eye is almost no feeling in flash), the audience need to set up wireless sensors to control the switching rate of the audience need glasses and the projector is switched rate synchronous. This system complexity, high cost of glasses, replace the battery is also very troublesome, cause management inconvenience glasses equipped with heavy viewers are less comfortable and not suitable for use in a number of three-dimensional multi-seat theater, but the number of visitors also can use less personal stereo theater projector is available with a single shot to the general curtain, support full HD high quality resolution 3D display mode, do not drop vertical resolution, but there is no distance limitations and ornamental perspective, the picture quality compared but it will reduce the high brightness. Currently, the major leading manufacturers have adopted the system prototype active shutter glasses, and said that this is to pass the full 1080p resolution to both eyes signal the best solution. As for the low-cost, 3D cinema use passive polarized glasses, can only pass 540 horizontal pixels per frame signals. However, there are some manufacturers at a lower price or for sports bars and other public places, 3D TV products with this 3d stereo glasses
