What is naked eye 3D LED curved screen?

After the rise of 3D technology in 2013, it caused a sensation in the LED display industry. However, in recent years, the development has been low-key, technical difficulties such as full-dimensional visual design, as well as restrictions on special content requirements, and blurred application scenarios, so that market awareness has not yet been popularized, and it has not been well applied. The Electronic Components Exhibition focuses on the comprehensive display of various electronic components and material products required for the design and production of electronic products. In this article, the editor of jyled analyzes how the naked-eye 3D LED curved screen achieves such a realistic effect.

Recently, South Korea’s SM company’s giant wave screen and Chengdu naked-eye 3D spacecraft giant screen have become popular, refreshing human’s new understanding of naked-eye 3D display technology, and it also means that 3D naked-eye technology LED display has returned to the public’s sight. And with its amazing display effect, it brings visual shock to people. And when more and more application cases are produced, it means that new progress has been made in products and technologies, and it is also being further accepted by the market.

The COEX K-Pop Plaza in 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 that wraps 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 various angles.

How to achieve such a realistic effect?

As we all know, our human brain is a complex nervous system, and anything that the human eye sees is three-dimensional. A picture with subtle differences, this subtle difference allows the brain to convert the spatial coordinates between objects in the direction of the disappearance of sight, 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 use glasses or other equipment to separate the content given to the left and right eyes of the viewer, so that the two glasses can obtain the images of the left and right eyes respectively, to the brain. It presents 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 the reference. 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.

This is not enough. Have you noticed that the 3D screens that have become popular recently are all composed of two surfaces with different angles. 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. When people stand in front of the corner and watch, they can see the object at the same time. Side and front, showing a realistic three-dimensional effect.

For more information, please pay attention to Shenzhen Electronic Components and Materials Sourcing Exhibition. Shenzhen Electronic Components and Materials Sourcing Exhibition (ES SHOW) is a commercial exhibition focusing on comprehensively displaying various electronic components and materials required for the design and production of electronic products. The exhibition is a component and material procurement platform for professional procurement personnel from various electronic product production and processing enterprises.
