Can Intelligent Projector Watch 3D? What are Differences Between Polarized and Shutter Projector?
What are differences between polarized 3D projector and shutter 3D projector? What kind of 3D projector we should buy? Today let's talk about the theory, advantages and disadvantages of 3D technology.
Now we go to the cinema to watch movies, many big movies are 3D, there are more and more home 3D products, such as 3D TV, 3D projector and so on. However, it is a little difficult to make a real choice. There are different types of 3D products. What is the difference between polarized 3D and active shutter 3D?Which is better?In this article, we will discuss the principles and advantages and disadvantages of different 3D technologies.
The differences between polarized 3D projector and active shutter 3D projector
Polarized 3D projector is also called time sharing projector, it is a display chip to realize the 3 d effect by increasing screen refresh rate and dividing the image into two, forming the corresponding two groups of left and right eye image, images staggered displayed in a row, the left and right pictures are transmitted by time error, so the LCD shutter glasses are used to distinguish whether the corresponding picture content belongs to the left eye or the right eye at a certain moment, and then the LCD quick switch is used to filter the picture and then the 3D image is automatically synthesized by the human brain.
Polarized 3D projector is also called non-flashing projector, we talked about the shutter projector is high frequency to refresh the image of the left and right eyes, that is high frequency flicker, so the non-flicker projector by definition is not flicker. It works in a completely different way from a shutter projector. The polarized projector itself has two light sources that can produce images of the left and right eyes simultaneously.
The principle is to set up polarized light 3D by two 2D projectors from top to bottom, and achieve the effect by polarizing film and computer operation, The operation of computer double output is complex, the alignment debugging of two projectors is troublesome, and the 3D effect of cinema level is difficult, but the two projectors cannot be moved easily, otherwise the effect will be affected, the cost of two projectors is relatively large.
