In recent years, the 3D wave screen of the SM Building in South Korea has sparked discussions on the Internet, and LED naked-eye 3D curved screens have become popular all over the world. These realistic display effects have refreshed the public’s perception of naked-eye 3D display technology. Glasses-free 3D screens from all over the world have been added to the Internet celebrity check-in packages for tourists, becoming a classic case of outdoor advertising, and “naked-eye 3D” has quickly become a hot word in the industry. All the amazing display effects are inseparable from the support of technology. Here is maxcolor to reveal the birth of the miracle for everyone.
How to achieve such a realistic 3D effect?
As we all know, our human brain is an extremely complex nervous system. Anything that the human eye sees is three-dimensional. This is because the two eyeballs of the human eye pass through the small distance between the human eyes and see the Two pictures with subtle differences, this subtle difference allows the brain to convert the spatial coordinates between objects in the direction in which the line of sight disappears, and we can also distinguish the distance and size of objects through this feeling, that is, Three-dimensional sense, that is, the sense of three-dimensional space.
Usually the basic principle of 3D display, such as 3D movies, is to separate the content for the left and right eyes of the viewer through glasses or other equipment, so that the two glasses can obtain the images of the left and right eyes respectively, and finally to What is present in the mind is the feeling of 3D images.
To achieve the naked-eye 3D effect of the display screen, the cost is much higher than that of wearing 3D glasses in the theater. In fact, most of the current LED large screens to achieve naked-eye 3D use the distance, size, shadow effect and perspective relationship of objects to build a three-dimensional effect in a two-dimensional picture. Just like when we look at sketches, painters can use pencils to draw three-dimensional images that are fake and real.
How to make a flat animation produce a 3D effect? Just make good use of references. We divide the ordinary picture into several layers through the white line, and then make the animation part “break through” the white line and cover the other elements of the layer, so that the parallax of the eyes can be used to form the illusion of 3D.
The 3D wave screen of the SM Building, which amazes the whole network as soon as it debuts, uses the shadow of the background as a static stereo reference line, giving the moving waves a feeling of breaking through the screen.
Not only that, the display screen folds the screen 90°, using video material that conforms to the principle of perspective, the left screen shows the left view of the image, and the right screen shows the main view of the image. To the side and front of the object, it presents a realistic three-dimensional effect.
The seemingly stunning display effect is behind countless technical polishing and strong product support.

Achieving stunning 3D display effects requires high refresh, high grayscale, high dynamic contrast, smooth transition between curved surfaces and corners, and the production level of video materials on the display screen hardware, which requires superior color expression. of stable display devices as support.
The outdoor display screen has achieved such a popular communication effect with naked-eye 3D, and it can be expected that more outstanding cases will emerge in the future. And with the development of technology and the reduction of cost, it is conceivable that the future LED display will no longer only rely on 3D video effects and multi-faceted screens, but will directly use the parallax effect of the screen hardware to present the real naked eye with more details. 3D images.
