The Beijing Winter Olympics was successfully held, and the LED display screen once again amazed the world!
The opening ceremony of the Beijing Winter Olympics held on February 4 made the world excited. Behind this feast of auditory and visual interweaving, the biggest “contributor” is none other than LED display technology.
The colorful LED floor screen, covering an area of more than 10,000 square meters, is currently the largest 8K ultra-high-definition ground display system; the beautiful and romantic Ice Cube, weighing about 400 tons, constitutes the world's largest pentahedral naked-eye 3D display device; the sparkling "snowflake"-shaped main torch platform is 15 meters in diameter , composed of 96 small snowflake-shaped and 6 olive branch-shaped LED double-sided screens; there is also a 60-meter-high, magnificent ice waterfall, and a crystal clear ice ring with a thickness of only 35 centimeters... These colorful visual technologies bring unparalleled "audio-visual enjoyment" to audiences around the world. Behind this wonderful "visual feast" is the success of local giants such as BOE, Leyard, Unilumin, Ledman Optoelectronics, Altai, Lopu, Nova Technology, Jingtai Optoelectronics, Chiptronics and other domestic giants with their LED screens to "dominate" the display.
The use of LED screens at the opening ceremony of the Winter Olympics set new records both in terms of scale and high technological content. It has shown to the world that China not only has world-class standards in design creativity, but also is at the top of the industry in terms of technological innovation and event guarantees. With the implementation of the national 5G+4K/8K policy and the implementation of the "100 Cities and Thousand Screens" project, the Winter Olympics has become a benchmark project for the application of LED display technology and the most powerful promotion force for the application of ultra-high-definition LED display technology. As a centralized display and military parade of my country's LED display innovative research and development results, the Winter Olympics may be regarded as a global-level advertisement for China's LED display technology.
It is reported that on the night after the opening ceremony, manufacturers including BOE, Leyard and others immediately released various news about the successful application of their related LED display products in the opening ceremony of the Beijing Winter Olympics. In the following days, other LED display manufacturers were also "following up" fermentation. It can be said that the LED screen is another "most eye-catching athlete" during this Winter Olympics.
An industry channel source said that compared with the opening ceremony of the 2008 Summer Olympics in Beijing 14 years ago, the LED display screen has overtaken the projector to become the undisputed "protagonist" in the opening ceremony of the Winter Olympics this time. This shows that the display category of LED display is playing a huge "advantage" in the high-end display application market.
It can be seen from the manufacturers participating in the two Olympic Games that the number of large-scale backbone enterprises has increased, forming a gathering effect of leading manufacturers, showing a grand scene of a hundred schools of thought contending; in addition, the LED industry has the rise of highly professional and deeply vertical market segment enterprises.
Comments from this magazine: The 2022 Beijing Winter Olympics has come to a perfect conclusion. The Chinese have used their own excellent new display technology to present the innovation and shock of Chinese science and technology to the world audience with stunning visual feasts. The strength of China's LED display screen was once again confirmed at the Beijing Winter Olympics. It is not only a large-screen, high-definition, high-color display, but also can achieve real-time intelligent interaction. This LED display screen has amazed the world and will lead the display industry into a new era, further promote the prosperity of the industry, and the development of China's new displays will also enter a new era.

Since 2022, the LED display market has attracted cross-border layouts from different industries, and industry giants have also expanded production and penetrated. Vertical integration of upstream, midstream and downstream is becoming the development trend of the LED display industry and will even change the traditional display industry structure in the future. As midstream packaging companies, they may face the advantages of upstream and downstream giants that are several times their size, or they may face the squeeze of cross-border capital. Once the new display industry market takes off, the advantages of traditional packaging companies will be weakened. In the face of huge capital, traditional packaging companies either join forces, are acquired or acquired, can only rely on differentiated products to occupy the market, or disappear.
Comments from this magazine: Vertical integration within the industry, as well as cross-border horizontal integration, may become the development trend of new displays in the future. The future development of the LED display packaging industry may bring profound changes to the entire LED display industry. The traditional division concept of upstream, middle and downstream may no longer exist. It is more likely that industry giants will vertically integrate the upper, middle and lower industries into product companies. In the future, it may be possible to realize consumer market brands and build self-produced and self-used integrated enterprises. With the deepening of cooperation, mergers and acquisitions have become a development trend, which will help stabilize the industrial chain of the LED display industry, strengthen product quality, accelerate the sinking of the supply chain, reduce costs, and realize the batch application of new Mini/Micro LED display products as soon as possible.
A seminar on incorporating LED display terminals into monitor energy efficiency standards was held
In the first quarter of 2022, a total of 79 "dual carbon" related policies were introduced across the country, including 18 national policies and 61 local policies. In order to comply with the development needs of the times, display screens will also be included in the scope of energy efficiency standards.
On October 28, an online and offline seminar on the "Display Energy Efficiency Limits and Energy Efficiency Levels" (202052552-Q-469) standard LED display partial energy efficiency levels was held in Unilumin Huizhou Daya Bay Science and Technology Park. The meeting was chaired by Hong Zhen, member of the National Standards Committee, deputy secretary-general of the China Optics and Optoelectronics Industry Association, and secretary-general of the LED Display Application Branch. Offline participating companies and representatives: Unilumin Technology team (Mr. Tian, Mr. Xiao Hua, Mr. Qi, Mr. Zhang, Mr. Wang, Wan Geng, Manager Bai, Tan Shenglin, Chen Wenyi), expert Luopu Li Nong, deputy secretary of the LED Display Application Branch of China Optoelectronics Association Cai Guangchao Chairman Cheng Senji, Secretary-General of the LED Association; Online participating companies and representatives: Sansi, Leyard, Lehman Optoelectronics, Alto Electronics, Absen, Lianjian, Xida Electronics, Qingsong Technology, Zhongqi and other industries. More than 60 companies from the upstream, mid and downstream industries, measurement, testing, engineering contractor alliances, local association representatives, etc. More than 100 people attended the meeting. The meeting specially invited expert Li Xilin to participate in this seminar.
This meeting introduced the standard background, policies and current development situation to everyone, and solicited the opinions of relevant enterprises, and finally provided unified feedback to the standard formulation unit.
For industries such as home appliances, energy efficiency standards can be seen everywhere, but for the LED display industry, they are still very unfamiliar. With the convening of the "Display Energy Efficiency Limits and Energy Efficiency Levels" (202052552-Q-469) standard LED display part energy efficiency level seminar, the introduction of relevant standards is just around the corner.
Energy efficiency standards, namely energy utilization efficiency standards, are standards that stipulate the energy utilization efficiency level of energy-using products or the energy consumption level within a certain period of time. Energy efficiency standards have high social and economic benefits. my country has promulgated and implemented 22 energy efficiency standards for energy-using products, involving household appliances, lighting fixtures and transportation vehicles.
The "Display Energy Efficiency Limit Values and Energy Efficiency Levels" (202052552-Q-469) standard is the first time that LED displays are included in the scope of the standard. According to the current "Display Energy Efficiency Limits and Energy Efficiency Levels" draft for comments (2022.9.19 PDF), LED display terminal energy efficiency levels are divided into three levels, of which Level 1 has the highest energy efficiency, and the energy efficiency is not lower than the requirements of Table 1 and Table 2 below.
In recent years, the market demand for standardized LED display products has been increasing. In particular, medium and large-sized indoor ultra-high-definition LED direct display terminal products have become more and more popular in the market. They are becoming a very important area in the rapid development of the industry. However, the market competition for related products has become increasingly fierce, with good and bad products mixed and difficult to distinguish. However, with the upcoming promulgation and implementation of the "Display Energy Efficiency Limits and Energy Efficiency Levels" (202052552-Q-469) standard, the entry threshold for some indoor segmented application markets in the industry will be raised, which will also be a challenge for some companies.
This magazine’s comment: In fact, if the country compulsorily introduces energy efficiency standards for display screens, it will also be a good thing for LED displays. The market will eliminate inferior products that fail to meet standards, and each company will pay more attention to product quality. The reputation of LED displays will become better and better, social acceptance will be higher, and the added value of products will increase accordingly. The market pie will become bigger and bigger. After the survival of the fittest, the entire industry will form a healthy development.
MIP packaging technology achieves breakthrough
In order to better develop Micro LED, Nationstar Optoelectronics announced on July 6 that it has launched a new packaging device solution. According to reports, the new MIP packaging device solution is based on the idea of fan-out packaging technology. Through a self-developed mass transfer method, a blackened substrate and a high-light extraction packaging route are used to construct a new MIP device, which greatly improves the photoelectric performance of the device. By amplifying the pin electrode, it matches the current machine equipment. It has the advantages of low cost, high brightness, low power consumption, strong compatibility, and mixable BIN to improve display consistency.

By amplifying the pin electrode, it matches the current machine equipment. It has the advantages of low cost, high brightness, low power consumption, strong compatibility, and mixable BIN to improve display consistency.
Nationstar Optoelectronics introduced that the MIP display module has high consistency, a black ratio of over 99%, a special optical design, a horizontal viewing angle ≥174°, strong compatibility, and is compatible with current equipment and machines. It can complete test sorting, easy detection and repair, and it is easier to apply Micro LED to the end market.
What is MIP?
MIP is a new packaging architecture based on Micro LED. The encapsulated MIP can be re-packaged with MCOB and can be produced using existing equipment, saving investment on the equipment side of the production line.
The process flow of MIP is to transfer the Micro LED chip to the carrier board through mass transfer technology, encapsulate it, cut it into single or multiple-in-one small chips, then split and mix the light of the small chips, and then perform the patching process and screen surface coating to complete the production of the display screen.
According to research reports from relevant institutions, Mini will be within P1.0 of H1 in 2022 COB packaging accounts for 30.8% of the LED market, which also shows that IMD/MIP packaging technology products have occupied a large market share in the field of fine pitch. At present, many upstream packaging manufacturers and LED display manufacturers have laid out MIP packaging technology routes, such as Nationstar, Leyard, Jingtai, Zhongqi Optoelectronics, Xinying Optoelectronics, etc. Among them, Leyard's simultaneous global release of the Micro LED black diamond series on June 30, 2022 attracted attention. Its point pitch is P0.9-P1.8, successfully achieving coverage of 80% of small-pitch products.
Micro LED COG technology can be applied to a lower pitch, but it is difficult to sort and test. In comparison, MIP technology has more advantages and is the best bridge between chips and backplanes. Sanan MiP 0404 products are currently in mass production, and 0202 has related products. Therefore, whether companies choose COB or IMD/MIP packaging technology, these will promote the iterative upgrade of small-pitch LEDs to Mini/Micro LEDs.
Comments from this magazine: At present, most companies are basically developing along the dual routes of SMD and COB. Affected by the overall macro environment and intensified competition, the sales of COB packaging products will also decline in 2022. Entering the Mini/Micro LED era, with the advancement of packaging technology, micro-pitch applications will change with each passing day.
Many screen companies have obtained DCI certification, and the era of LED movie screens is coming!
In January 2022, Dongguan Altai Display Technology Co., Ltd.’s nationally produced 4K LED movie screen passed Hollywood DCI certification! The LED cinema screen that was certified this time was independently developed and produced by AET Altai, and the image processing system was jointly developed and produced by AET Altai and domestic system and player companies, achieving national production! AET has thus become the first Chinese company in China to realize the national production of LED cinema screens and image processing and playback systems, and to pass Hollywood DCI certification!
In February, Shanghai Muge announced that the GS01 LED cinema screen it developed passed the test of the US DCI testing agency and officially obtained the Hollywood DCI certification.
In March, AET Altai's 2K 10m cinema screen once again received Hollywood DCI certification, making AET the first domestic LED display company to have both 2K and 4K 10m cinema screens pass Hollywood DCI certification.
