Since 2021, the naked-eye 3D screens has been frequently searched on Weibo, and the video has been forwarded and played more than 100,000 times.

In addition to the hot search list, naked-eye 3D will also blossom everywhere in 2021. What trends are hidden behind these new changes? What will be the link to the development of the display market in 2022? In this context, the expert said that the Industry Research Center will cooperate with the core manufacturers of the LED display industry to conduct in-depth research to entertain you.

Hot search list

It has to be said that naked-eye 3D display will become the “top stream” of the LED display industry in 2021.

Take the naked-eye 3D large screen built by Lianjian Optoelectronics for the core business district of Taikoo Li, Chunxi Road, Chengdu as an example. Once the naked-eye 3D spaceship giant screen was unveiled, it not only attracted the attention of the public, but also received a large number of forwarded comments from the whole network.

Weibo’s real-time hot search TOP5, with a cumulative total of 320 million hits. It is worth mentioning that the project has a resolution of 8K and a total area of ​​888 square meters. Under the “dual-screen linkage” between the naked-eye 3D giant screen and the 450 square meters ultra-high-definition screen on the side, it has injected new vitality into the Chunxi Road business district.

Coincidentally, it is comparable to Chongqing’s “3788 Light of Asia” naked-eye 3D large screen, which is located in the center of the Guanyinqiao business district in Chongqing and is built around both sides of the Suning Tesco building. The ultra-high-definition LED display with a total area of ​​3788 square meters and a resolution of 8K is called “the first screen in Asia”.

Among them, the naked-eye 3D project version 1.0 with the theme of “future city” and the naked-eye 3D version 2.0 version of “light rail through the building”, the vivid stereoscopic visual effect combined with the ultra-large ultra-high-definition screen, the shocking visual experience caused continuous cheers from the onlookers. With amazement, the number of related videos spread on the entire network exceeded 100 million, and more people knew about the giant screen in Chongqing. This large screen has thus become a new business card for the city of Chongqing.

In addition to the above-mentioned naked-eye 3D large screens, the naked-eye 3D screens created by JYLED, LED SCREE, and HOLA-LED for first and second-tier cities are also eye-catching and frequently appear in the live broadcast rooms of major coffee shoppers , to become the city’s Internet celebrity check-in place.

2021’s “big changes”

Glasses-free 3D displays have achieved huge changes in 2021, both in terms of quantity and area.

First, there has been a marked spike in numbers. According to the statistics of the Industry Research Center, as of the end of December 2021, the number of naked-eye 3D projects nationwide was close to 100 and maintained a rapid growth trend. Many display manufacturers even said that more projects will be launched in 2022.

In addition, in terms of area, naked-eye 3D has achieved an amazing breakthrough. Taking my country’s TOP20 display manufacturers as an example, many display manufacturers such as JYLED, HOLA-LED and LED SCREE have achieved an area of ​​the order of 1,000 square meters. Achieved a breakthrough of 10,000 square meters.

From a regional perspective, the landing of naked-eye 3D displays basically starts from first-tier cities and develops in a point-line-surface state.

For the surge and explosion of the number of naked-eye 3D, the expert industry research center believes that it is mainly due to the following three points:

The commercial value behind naked eye 3D

Compared with traditional LED outdoor large screens, the development of naked-eye 3D large screens not only further enhances the image of the city, empowers the local economy, and rejuvenates the commercial vitality under the new consumption trend, but also enhances the visual shock and interactivity. Improve advertising effectiveness.

For the city, the large outdoor screen with a great sense of picture and the surrounding buildings have already evolved into a symbol of a city. The naked-eye 3D technology has a sense of space, successfully draining traffic for business circles and commercial entities, increasing audience participation, not only activating The commercial value of the business district also promotes the improvement of urban soft power and local economy.

From the perspective of the landing position of naked eye 3D, they are all distributed in important business districts such as cities. In addition to Chengdu and Chongqing mentioned above, there are also many first- and second-tier cities such as Beijing, Guangzhou, Shenzhen, Wuhan, Shenyang, Hefei, Wuxi, and even the business districts of third-tier cities competing to introduce naked-eye 3D large screens.

In a short period of time, the sensational effect caused by the naked-eye 3D display is also thought-provoking. Most industry manufacturers believe that this is mainly due to the production of naked-eye 3D content.

On the other hand, in terms of hardware, after years of development and precipitation, LED large screens have taken a dominant position in the outdoor market. Several display manufacturers such as Leyard, Ledman Optoelectronics, Lanpu Video, LED SCREE senior visual design director said that the current naked-eye 3D screens used for outdoor use range from P3-P10 according to the size of the screen; in addition, the dot pitch The choice of the device is related to the best viewing position and total area of ​​its installation location.

At present, the outdoor display technology is mature, the supply chain is well matched, and the product price is lower. In order to pursue better display effect, the resolution of the display screen is 4K or even 8K.

In this regard, LED SCREE believes that the selection of point spacing can refer to the following two points, and the maximum spacing is not greater than:

(1) According to the best viewing distance/3000

(2) Press the width of the display/3840

What cannot be ignored is that in order to present a higher-definition, smoother, and more realistic naked-eye 3D effect, in addition to extremely high requirements for playback materials, there are also very high requirements for video playback control systems and LED displays. Nova Nebula believes that from the perspective of display control system and video processing, it is mainly reflected in three aspects: high refresh, high grayscale, and high dynamic contrast; ultra-high pixels, ultra-large loading; ultra-8K high-resolution material decoding. .

In addition, on the energy consumption and operating costs of the two large screens, the views of each company are generally the same.

JYLED: The hardware cost is not much different from the traditional outdoor screen, mainly because the film source is more expensive. But in order to achieve visual effects, the hardware also needs to work hard. In this regard, Leyard has improved the production process to achieve a higher contrast ratio, using a patented driver IC, which can achieve high-level HDR.

HOLA-LED: Under the same configuration conditions, the power consumption of the naked-eye 3D screen is almost the same as that of the traditional outdoor display. In essence, the outdoor naked-eye 3D screen has made some structural changes on the original basis, such as the left and right sides of the box and the module are designed with chamfered corners to facilitate splicing at right angles; while the lamp beads, IC, power supply, PCB board, etc. There is no change, no effect on power consumption. In terms of operating costs, there is no big difference between the two.

3d led display screen

LED SCREE: The key to naked-eye 3D itself is the content, and there is no absolute technical requirement for the screen. Because naked-eye 3D is generally a secondary transmission of video media, it is inevitable to be shot by a mobile phone or camera. In order to avoid screen flicker or the appearance of scan lines when shooting the screen, a higher refresh rate may cause the power consumption of the screen to rise. , but for the revenue generated by the operation of the naked-eye 3D large screen, this cost seems to be a drop in the bucket.

Generally speaking, compared with the general traditional large screen, the cost of naked eye 3D is not much different in terms of hardware. The main cost pressure is still from content production, but the revenue generated by its commercial value makes up for the content production cost to a certain extent.
