How Does The Naked Eye 3D LED Curved Screen Achieve Such A Realistic Effect

After the rise of 3D technology in 2013, it caused a sensation in the LED display industry. However, in recent years, low-key development, technical difficulties such as full-dimensional visual design, restrictions on content-specific requirements, and fuzzy application scenarios have made the market awareness still not popular, and it has not been excellently applied.

Recently, South Korea’s SM company’s huge screen and the Chengdu naked-eye 3D spaceship giant screen became popular, refreshing human’s new understanding of naked-eye 3D display technology, and also means that the 3D naked-eye technology LED display is back in the public’s sight. And with the amazing display effect to bring people a visual shock. When more and more application cases are produced, it means that there are new developments in products and technologies, and they are being further accepted by the market.

SM "Korea Wave Glasses-free 3D LED Display" is popular all over the world

The COEX K-Pop Plaza at Samseong Station in Seoul, South Korea, can be said to be the birthplace of the Korean Wave. Just outside the COEX Convention and Exhibition Center, there is a huge display covering the building. This is actually a huge naked-eye 3D LED curved screen. The realistic effect makes it difficult for the audience to distinguish the true from the false from all angles.

How to achieve such a realistic effect?

As we all know, our human brain is an extremely complex nervous system. Everything the human eye usually sees is three-dimensional. This is because the two eyeballs of a person pass a small distance between the human eyes, and what they see is Two nuanced images. This nuance allows the brain to calculate the spatial coordinates of the objects in the direction where the line of sight disappears. We can also distinguish the distance and size of the objects through this feeling. The sense of three-dimensionality, that is, the sense of three-dimensional space. Generally, the basic principle of 3D display, such as 3D movies, is to use glasses or other equipment to separate the content area for the left and right eyes of the viewer, so that the two glasses can obtain the images of the left eye and the right eye respectively, and finally What is presented in my mind is the feeling of a 3D image.

The cost of the display screen to achieve the naked eye 3D effect is much higher than that of wearing 3D glasses in the theater. At this stage, LED large screens realize naked-eye 3D, in fact, most of them use the distance, size, shadow effect, and perspective relationship of the object to construct a three-dimensional effect in the two-dimensional picture. Just like when we look at sketches, painters can draw fake and real three-dimensional images on a flat surface with a pencil.

How to make a flat animation produce 3D effect? Just make good use of the reference object. We divide the ordinary picture into several layers by white lines, and then enable the animation part to "break through" the white lines and cover other elements of the layer, so that the parallax of the eyes can be used to form a 3D illusion.

As soon as it appeared, the 3D wave screen of the SM building that surprised the entire network used the shadow of the background as a static three-dimensional reference line, giving the moving waves the feeling of breaking through the screen.

This is not enough. Have you discovered that the recent popular 3D screens are all composed of two different angles. The display screen folds the screen 90°, using video material that conforms to the perspective principle, the left screen displays the left view of the image, and the right screen displays the main view of the image. When people stand in front of the corner and watch, they can see the object at the same time. The side and front sides present a realistic three-dimensional effect.
