The reason why people can see three-dimensional scenery is because our two eyes can each see things independently, the left and right eyes have a spacing, resulting in some slight differences in the perspective of the two eyes, and such differences will make the two eyes individually see a little displacement of the scenery. And the difference between the left eye and right eye images is called parallax, the human brain is very clever to fuse the images of the two eyes, producing a spatial sense of three-dimensional visual effects in the brain.

Since there is only one computer screen, but we have two eyes, and it is necessary to make the images seen by the left and right eyes each independently separate to have stereo vision. At this point, this parallax can be continuously represented on the screen through 3D stereo glasses.

Through the control IC to send stereo signals (left eye -> right eye -> left eye -> right eye -> sequential successive alternate repetition of each other) to the screen, and at the same time send synchronization signals to the 3D stereo glasses, so that they synchronize the left and right eye images, in other words, the left eye to see the left eye should see the scene, the right eye to see the right eye should see the scene.

3D stereoscope is a penetrating LCD lens, through the circuit to the LCD glasses on, off the control, on can control the glasses lens all black, in order to cover a glance image; off can control the glasses lens for transparent, so that the other eye to see the other eye should see the image.

3D stereo glasses can imitate the real situation, so that the left and right eye images continuously alternate with each other on the screen, and synchronize with 3D stereo glasses, coupled with the physiological characteristics of the human eye visual temporary, you can see the real stereo 3D images.

The market with 3D / VR stereo glasses application of stereoscopic images of a wide variety. The most common display modes are mainly four kinds: Interlacing, Page-Flipping, Line-Blanking and Sync-Doubling.

Here are a few of the Vr virtual glasses products on the market:
