The reason for the sudden explosion of naked-eye 3D LED display

At present, with the continuous advancement of technology, the functions and effects of traditional products are also changing. The traditional LED display screen used for scrolling information has gradually become a “door brick” to attract customers. The big screen is no longer a simple large advertising screen, but also changed people’s concept of space, from flat 2D to three-dimensional 3D.

In major internet celebrity cities and bustling business districts, a wave of urban screens has emerged. The various forms in the city seem to be a business card of the city, telling everyone the strong cultural heritage and small town stories.

In fact, 3D naked-eye technology was not launched in recent years, and the technical concept was outlined more than 10 years ago. A few years ago, Sharp, Samsung, HTC and many other manufacturers have launched products equipped with naked-eye 3D display technology on their electronic products, but there was no big wave at that time. At present, the outbreak of 3D screens is mostly caused by the investment of marketing expenses.

Its sustainability usually depends on the cost of promotion and marketing. It’s the same with most internet celebrities today. It is good to be popular for 1-2 years, and most Internet celebrities often cannot last for a year. Because the lifespan of an influencer has a lot to do with the marketing company it signs with, once the marketing company has a new goal or idea, it is replaced, and then there is no news.

However, the naked-eye 3D LED display screen, which is also a net red product, is different. Although the principle of 3D naked-eye technology is not complicated, its excellent visual presentation and marketing promotion alone are not enough to make it so popular. The real reason we need to trace from the media.

For the surge and explosion of the number of naked-eye 3D, some experts believe that it is mainly due to the following three points:

The commercial value behind naked eye 3D

Compared with the traditional LED outdoor large screen, the development of naked-eye 3D large screen not only further enhances the city’s image, empowers the local economy, and rejuvenates the commercial vitality under the new consumption trend. 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 the business circles and commercial entities, enhancing the audience’s 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, which are 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.

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.

LED PM believes that from the perspective of display control system and video processing, it is mainly reflected in three aspects: high refresh, high grayscale, high dynamic contrast; ultra-high pixel, ultra-large load; ultra-8K high-resolution material decoding.

Improve the company’s own strength

From the source, naked-eye 3D fire is mainly due to the progress of its video source production technology and price decline, as well as the progress of supporting software and hardware technology. At the same time, upstream and downstream manufacturers of LED displays are also actively guiding and promoting the development of naked-eye 3D projects, and investing resources to promote the advancement of naked-eye 3D-related software and hardware technologies.

policy support

In recent years, the state’s investment in the cultural tourism industry and the ultra-high-definition display industry has indirectly driven the market sales and dissemination volume of naked-eye 3D screens, and is also conducive to creating a new business card for city representatives.

In early May 2021, the Ministry of Science and Technology of Mainland China released the “National Key R&D Program “Mathematics and Applied Research” and other “14th Five-Year” key projects in 2021, and the “National Key R&D Program “Information Photonic Technology”, etc.

The “14th Five-Year Plan” Key Special Project Application Guidelines for 2021″, the projects released this time have a total of nearly 5 billion national funds. Among them, the key technology research and development of naked-eye 3D display core optical devices and common technologies and architectures are included in the list.

It is understood that in order to present the experience display effect of naked eye 3D, the hardware of the display screen needs to achieve better contrast ratio and HDR high dynamic range, high refresh, high grayscale, high dynamic contrast, curved surface/ There are high requirements for the smooth transition of corners and the production level of video materials. Under the encouragement of the policy, glasses-free 3D display will be further developed.

On January 10, 2022, the Ministry of Industry and Information Technology, the Central Propaganda Department and other six central departments issued additional codes and issued the “Guidelines for the Implementation of the “One Hundred Cities and One Thousand Screens” Activity” to effectively promote the integrated development of ultra-high-definition video and various industries.

From the analysis of the purposes of cultural publicity, urban image, consumption upgrade, and industrial innovation emphasized in the policy, corresponding to the important urban business districts, large-scale comprehensive transportation hubs, Internet celebrity landmarks, cultural venues and other scenarios have huge development potential in major cities.

Therefore, the naked-eye 3D LED display is associated with the policy requirements of some countries. In some countries, due to the injection of government funds, enterprises have increased the research and development and progress of LED display screens.
