Why a expensive, a cheap, what's the difference?
Hello friends, the initiative is the shutter type, also known as the time fraction,The principle is to make the glasses around the initiative to open and close, to achieve the two eyes can not see the same angle of the image, resulting in a three-dimensional sense of the brain.Corresponding to the active type is polarized, also known as polarized light, polarized, non flash. The 3D technology is very mature, lower cost
3D common glasses? The theory can not be, in view of the cinema can only use matching glasses, but now the computer has a variety of 3D viewing software, can make the format of the 3D film output is more and more common red and blue or red format, can watch with red and blue or red green glasses, in other words in the computer can use a pair of glasses to watch 3D movies in different formats. So what is the difference between the 3D polarized lens and the active shutter? Let's take a look at it.3D glasses universal?3D glasses are not universal.1.3D glasses are not universal, dividend blue, red, green, polarized, shutter glasses, different glasses look different formats of 3D movies.2 different types of 3D film can not use the same glasses.The theory can not be, in view of the cinema can only use matching glasses, but now the computer has a variety of 3D viewing software, can make the format of the 3D film output is more and more common red and blue or red format, can watch with red and blue or red green glasses, in other words, the computer can with a pair of glasses to watch 3D movies in different formats.3 red and blue color, the red color is the output format, up and down, left is the original film in the cinema format, or professional 3D TV can directly see the format, because the cinema projector or professional 3D TV hardware support, as to what kind of hardware I also not clear, you can ask the relevant people with polarization or shutter glasses you can watch, but the computer can only see the red and blue or red, not directly after or about the format of the hardware does not support.

Two, mainly rely on active shutter 3D technology active shutter 3D imaging principle of active shutter 3D technology is LCD glasses to achieve the stereo imaging, its essence is the lens control on / off two LCD screen, a liquid crystal layer in the eyes with black and white two kinds of state, often appear as flat white is a transparent state, electricity will become black. By means of a signal transmitter, precise synchronization between the 3D eyes and the screen is achieved. Generally, 3D active shutter technology is constantly through the lens imaging of high speed on / off state to achieve 3D stereo images, from this point of view, is bound to cause long time watching the film appear dizziness or fatigue eye discomfort occurs. 3D active shutter glasses 3D active shutter technology advantages: less 3D, blur effect is prominent, which can achieve full HD 3D output, the cost is relatively low only need to update the screen refresh rate to 120 Hz can import this technology. Active shutter 3D technology disadvantages: long time use easy to cause eye fatigue and even dizziness, matching the active shutter 3D glasses price is more expensive glasses need to charge and more heavy.
