Polarized 3D and active shutter 3D difference interpretation [Photo]
What is the difference between polarized 3D and active shutter 3D? Many friends now ask such questions. Why is this? Because, 3D technology is not limited to space (plane), the screen size is no longer constrained by the screen, the audience sees through the 3D technology, the picture is realistic and delicate, as if on your side. In addition, more and more 3D products are now available, such as 3D TVs and 3D projectors.
But in the real choice of whether it is difficult, 3D products even have a classification, which is what we said above, polarized 3D and active shutter 3D, these two technologies have any difference? Which is better? Let's find out the difference between polarized 3D and active shutter 3D.
Polarized 3D and Active Shutter 3D Difference: Principle
1, Polar 3D principle
Polarized 3D imaging technology uses the principle of "vibration direction" to decompose the original image. By placing a polarizer on the display screen, two pictures with different polarization directions can be delivered to the viewer when the picture is polarized. In the eyes, each lens of the polarized eye can only receive one polarization direction image, so that the left and right eyes of the person can receive two sets of images and then synthesize a stereoscopic image through the brain.
2, active shutter principle
The active shutter 3D imaging technology achieves 3D effects through the refresh rate of the screen. By dividing the image into two frames, two sets of screens corresponding to the left eye and the right eye are formed and continuously interlaced and displayed, and the infrared signal transmitter is simultaneously The left and right lenses of the shutter-type 3D glasses will be switched synchronously so that the left and right eyes can see the corresponding screen at an accurate moment.
The above technique can maintain the original recognition rate of the picture and it is very easy for the user to enjoy true full HD 3D effects without causing the picture brightness to drop. Under normal circumstances, the refresh rate of the 3D liquid crystal screen must reach 120 Hz or more, that is, let the left and right eyes receive images with frequencies above 60 Hz to ensure that the user sees the continued and unblinking 3D image effects.
Polarized 3D and active shutter 3D which is good
Polarization type 3D: From the above principle, we know that with polarized 3D technology, only one polarization direction picture can be seen in each human eye, which weakens the trueness of the image, although the combination of the two can also complete imaging. However, in fact, the picture has been lost during the imaging process. In one sentence, the explanation is “half the resolution, that is, the screen resolution is only half the originalâ€. In other words, if it is 1080P resolution, at most, You can also see 50% of the clarity.
Active Shutter 3D: Compared with polarized 3D, the resolution of the screen brought by active shutter 3D technology is real and there will be no loss. Who is 1080P is 1080P, 3D is the best but active shutter 3D In bright conditions, there will be easy flicker (and polarized 3D will not flicker, so polarized 3D is also called no flash 3D), long-term viewing will feel eye fatigue, and even dizziness, vomiting.
Polarized 3D glasses and active shutter 3D glasses
Polarized type 3D glasses: 3D glasses are cheap and light, no need to charge, the price advantage is obvious, and it is easier to be paid attention to cost-effective mass consumers.
Active shutter 3D glasses: The price of active shutter 3D glasses is relatively expensive, glasses need to be charged and thick, and wearing ear for a long time can be very tired.
