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

Recently, South Korea’s Wave giant wave display and Chengdu naked-eye 3D spaceship 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 screen has returned to the public’s sight. Bring visual shock to people with amazing display effects. 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.

SM’s “Korea Wave Glasses-free 3D LED Display” is popular all over the Internet

The COEX K-Pop Plaza at Samseong Station in Seoul, South Korea, can be said to be the birthplace of Hallyu. Just outside the COEX Convention and Exhibition Center, there is a huge display that wraps the building. In May of this year, d’strict, a local design company specializing in image, space and visual experience in Seoul, designed a huge LED installation art: “Wave” in the birthplace of the Korean Wave, which is actually a huge naked-eye 3D LED curved surface The screen, created by digital media company Dilussion, K-pop idol SM Entertainment, and Samsung Electronics, is so realistic that it is difficult for viewers to tell the difference between the real and the fake from various angles.

Note: The screen is 20m high and 80m long. D’strict is on the naked-eye 3D screen. By simulating the state of the waves rolling in the building, it presents an amazingly realistic effect.

Chengdu naked-eye 3D spaceship LED 8K giant screen became popular

In October 2020, the giant screen of the naked-eye 3D spaceship built for Chengdu was lit up with shock, and the cool black technology display instantly detonated the comments from the national and even overseas media. Weibo real-time hot search TOP5, the cumulative total hits reached 320 million. A large number of fans rushed to the scene to experience the ultimate visual experience brought by the naked-eye 3D large screen.

It is understood that this Internet celebrity LED giant screen is located in the core business district of Taikoo Li, Chunxi Road, Chengdu. The project has a resolution of 8K and a total area of ​​nearly 1,000 square meters. The naked-eye 3D giant screen and the 450 square meters ultra-high-definition screen on the side can be “dual screen”. “Linkage”, the project specially presents diversified details for different scenes of day and night, such as 90° seamless corner module technology, outdoor high-brightness wide-angle display panel technology, high-contrast light-absorbing masks, etc., to break the border of art at one time, let the whole The wall was immediately injected with new life of naked-eye 3D digital technology, making this creative large screen radiate up to 400,000 people a day, and the ROI of traditional outdoor advertising can be increased by at least 3 times. This performance can be regarded as a typical case that can be recorded in the history of outdoor commercial display.

According to the line information, the packaging devices used in the latter two cases are from the flagship product of the RGB packaging leader-National Star RGB Super Division, which provides better picture support for the display screen from the perspective of light source.

So, in addition, compared to 2013, what technological advancements are there in the frequent appearance of naked-eye 3D LED displays? What are the differences in software and hardware between naked-eye 3D LED displays and traditional displays? What is the future trend?

We took the opportunity to interview Mr. Zhang Yu, the senior engineer of LED scree, the representative of the cases presented above, and made a professional interpretation:

In terms of hardware: Compared with traditional products, the naked-eye 3D LED display pays more attention to high refresh rate, high gray scale, high dynamic contrast ratio, and smooth transition between curved surfaces and corners; in addition, the playback server needs to be connected to a professional graphics workstation and configured with multiple graphics card frame synchronization cards ;

In software: a more professional decoder is required, the decoder must be able to support the material mapping and correction functions of the special-shaped display carrier, and support the underlying optimization of high-code stream decoding;

On the playback material: there are also certain attention to the selection of the main viewing angle, which requires a three-dimensional structure based on the perspective relationship of the display shape, and the resolution is customized point-to-point. In order to ensure the best display effect, it is recommended to use the HAP format;

Technological progress: In addition to the advancement of software and hardware in recent years, the improvement of the production level of materials has also played a major role. At present, the production of videos is polished according to the requirements of high-quality products. In addition, the artistic structure of the structure also makes it no longer limited to the traditional flat screen, and has more imagination space.

The development trend of 3D LED screen in the future: the outdoor single screen area is larger, the pixel density is larger, the overall effect is more shocking, and the image details are clearer. The current content display is mostly in the form of Internet celebrity punching cardbo eyeballs, but it will be commercialized in the future Bless, reflect higher value.

To sum up, we can see that the vivid and lifelike pictures are amazing. LED display manufacturers are reintegrating naked-eye 3D LED displays into outdoor buildings. We expect this initiative to drive a new wave of trends.
