What is really 3D LED Display?

After the rise of 3D technology in 2013, The discussion of a really 3D LED display has not stopped.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 been popularized, and it has not been well applied.

Recently, South Korea’s Wave giant wave display and Chengdu naked-eye 3D spacecraft giant screen became popular, refreshing human’s new understanding of naked-eye 3D display technology, and also means that 3D naked-eye technology LED display screen has returned to the public’s sight. , and 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. COEX K-Pop Plaza in Samseong Station, Seoul, South Korea, can be said to be the birthplace of Korean Wave. 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 amazing and realistic effect.

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

In October of the early years, the naked-eye 3D spaceship giant screen built by Lianjian Optoelectronics for Chengdu was shocked and lit up, and the cool black technology display instantly detonated the comments of the national and even overseas media, and the real-time hot search TOP5 on Weibo, the cumulative total number of clicks 320 million.

A large number of fans rushed to the scene to experience the ultimate visual experience brought by the 3D LED 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.

Guangzhou naked-eye 3D curved screen becomes popular

In addition, the 8K ultra-high-definition naked-eye 3D curved screen was unveiled in Xindaxin Department Store, Beijing Road Pedestrian Street, Guangzhou, and it also became popular for a while. The total area is about 1200 square meters, and its resolution exceeds 9440 points horizontally and 3520 points vertically. With the support of naked-eye 3D technology, the viewer can see a spatial and three-dimensional picture without the aid of 3D glasses and other auxiliary equipment, and has a strong visual impact.

In addition, tourists can also participate in the interaction through AR technology screen projection, scan QR code to download APP, push greetings to the big screen, participate in on-site lottery draws and grab red envelopes, etc., to enhance the diversity of business district operators’ marketing activities and stimulate consumer demand. .

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

So, apart from that, compared to 2013, what technological advancements are there in the frequent appearances of naked-eye 3D LED displays? What are the differences in software and hardware between naked-eye 3D LED screens and traditional screens? What is the future trend? We took the opportunity to interview the representative of the cases presented above – Mr. Sun, a senior engineer at JYLED, 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 terms of software: a more professional decoder is required, which must be able to support material mapping and correction functions for special-shaped display carriers, and support the underlying optimization of high-code stream decoding;

Playing material: There are also certain attentions. The selection of the main viewing angle needs to be based on the perspective relationship of the display shape to make a three-dimensional structure, and the resolution can be customized point-to-point. 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 eyes of JYLED: 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 eyes, but the follow-up will be commercial Blessing, reflecting higher value.

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