Shenzhen Lianchengfa Technology Co., Ltd.

On October 16, the 20th National Congress of the Communist Party of China was held in Beijing. The report of the 20th National Congress of the Communist Party of China pointed out that we must insist on focusing on the development of the economy on the real economy, promote new industrialization, and use the strategic theme of high-quality development to guide China's manufacturing industry to accelerate its march to the high end of the industrial chain. Under the background of the new global economic development with unprecedented changes in a century, the development of my country's manufacturing industry is constantly moving towards a higher level in innovation, leading to more cutting-edge technology, from keeping up with others to leading development, in various " Actively adjusting the development strategy in the "Black Swan" event, this is the self-adjustment of my country's manufacturing industry, and it is also a clear understanding of the development trend of my country's manufacturing industry. As the downstream application end of the LED industry chain, the LED display industry also adheres to the principle of high-quality development and has innovations everywhere in technology and application. So from the 19th National Congress to the 20th National Congress, what changes have taken place in the LED display industry in the past five years?

Small pitch to smaller pitch

In 2017, the development of small spacing has been relatively mature, and with more and more LED display manufacturers competing for the field of small spacing products, the small spacing market is also growing exponentially and gradually becoming the mainstream market. Due to the prosperity of its market, many companies have also explored a variety of packaging processes while laying out small-pitch products, thus pushing the trend of fine-pitch LED displays to the peak. The application market of small-pitch LED products is the first to explode in the domestic market. There is a strong demand for military applications, security monitoring, traffic command centers, and large video conference rooms. As production costs are gradually effectively controlled, some display manufacturers are not limited to indoors or outdoors. , began to focus on the development of indoor and outdoor products. While the indoor small pitch is moving towards a smaller pitch, the outdoor small pitch market is gradually gaining market demand, and the dot pitch is also constantly going down. In 2019, COB technology is mature, and the industry recognizes that COB packaging is the best choice for small-pitch LED displays, bringing the small-pitch LED display market into the next stage of development.

By 2021, Mini LED will enter commercial use, and the market share of Mini LED products will grow rapidly. As the transition technology of LED display technology from small pitch to Micro LED, the development of Mini LED has attracted much attention. In July this year, Shenzhen released the certification standard for Mini LED commercial display screens, which are suitable for Mini LED chips with a chip size of less than 200um, a pixel pitch range of 0.3-1.5mm, and indoors operating at 0-40°C and humidity below 85%. Ultra-high-definition display using the Mini LED direct display solution in the environment. At the moment when the industry lacks standardized development, the determination of this standard also fills the domestic vacancy and further promotes the development of Mini LED from the aspect of industry standards.

Since the beginning of this year, Micro LED has ushered in a period of rapid development. Leading screen companies have successively deployed related products, and have made major technological breakthroughs in mass transfer. With the explosion of the metaverse concept, its development has accelerated again. On the application side, LED manufacturers such as Leyard, Lehman, and Lianchengfa have already used Micro LED displays in scenarios such as command centers and monitoring centers.

In the past five years, with the joint efforts of most screen companies in the industry, LED display technology has achieved leapfrog development from small pitch to fine pitch, and is also innovating in the direction of finer pitch and more ultra-clear.

The field of transparent display is more subdivided

As a subdivision of the display industry, LED transparent screens have a brand-new visual experience, application experience and unique display methods, which are full of sense of technology; light and thin appearance design, full of sci-fi color display effects, in the current urban curtain wall construction, Advertisement display, landscape exhibition, shopping mall canopy and other fields have unique advantages. Although it has a wide range of applications, it was not "welcome" in the LED display market in the early days. In the past, the transparent screen market was not well received, mainly because the early products were not yet mature and were only improved from grid screens. There are many customized products, low quantity and high cost, which is one of the reasons why transparent screens are hindered from expanding into the market. However, in 2017, the transparent screen market has grown significantly compared with previous years. Due to technological progress, the price of transparent screens is closer to the market. Compared with previous years, the price of transparent screens has dropped by nearly half. Also in 2017, many provinces and cities across the country issued regulations on the dismantling of large outdoor conventional display screens, which also gave a good opportunity for the development of transparent screens that can be installed indoors and viewed outdoors. With the further development of urbanization, the demand for transparent screens in glass curtain wall structures is also increasing. In addition, 4S stores and the recovery of the stage rental market also provide good development opportunities for the development of transparent screens.

So far, LED transparent screens have also been subdivided into LED film screens, LED crystal film screens, and LED photoelectric glass. In terms of material selection and technical process, they are lighter, thinner and more transparent than traditional transparent screens, and have a wider range of applications. . In the night travel economy and the cultural tourism market, the application of LED transparent screens has also become ubiquitous in recent years. Relevant agencies predict that by 2025, the market output value of LED transparent screens will be about 87.2 billion US dollars. LED transparent screen has risen rapidly in a short period of time with its new application form, leading technology development and design concept close to the needs of the public, and a new blue ocean market has taken shape.

It can be said that in the past five years of development, LED transparent screens have not only achieved expansion in terms of market size, but also developed in depth in their own subdivisions.

Creativity Shows Blooming Flowers

The development of LED display is not only innovation in technology and category, but also a more diversified display in form. For example, LED special-shaped screens, LED flexible screens, naked-eye 3D large screens, etc., and also drive the trend of customized solutions. The development of LED special-shaped screens and flexible screens is relatively early, and it has corresponding professional capabilities for the cultural tourism market and specific stage performance needs. In the field of creative display, the most representative is the naked-eye 3D large screen, and the naked-eye 3D large screen will really enter the public's field of vision when the nearly 1,000-square-meter "spaceship" naked-eye 3D in Taikoo Li, Chengdu in 2020 has aroused the enthusiasm of netizens. It became a classic case in the history of naked-eye 3D, and thus set off an upsurge of naked-eye 3D.

According to statistics, in the future, there will be 200 million naked-eye 3D digital display screens in the world, and there will be about 50 million in the Chinese market, with a market value of about 370 billion. On January 10, 2022, six central departments including the Ministry of Industry and Information Technology and the Central Propaganda Department issued the "Guidelines for the Implementation of the "Hundred Cities and Thousand Screens" Campaign" to effectively promote the integration and development of ultra-high-definition video and all walks of life. , Consumption upgrade, industrial innovation and other purposes are analyzed, corresponding to important urban business districts, large-scale comprehensive transportation hubs, Internet celebrity landmarks, cultural venues and other scenarios that have great development potential in major cities, and have become an important driving force for the explosion of naked-eye 3D display.

Despite the popularity of naked-eye 3D, there are very few companies in the industry that can really afford the production cost of a complete solution of "hardware + software + system", most of which are Unilumin, Lianjian, Absen, and Lianchengfa. Some screen companies have case presentations on a full set of solutions. In fact, in order to present a higher-definition, smoother, and more realistic naked-eye 3D effect, in addition to high requirements for the hardware of the LED display, there are also high requirements for the video broadcast control system and playback materials. From the source, the popularity of glasses-free 3D is mainly due to the advancement of its video source production technology, the decline in price, and the advancement of supporting software and hardware technologies. At the same time, upstream and downstream LED display manufacturers are also actively guiding and promoting the development of glasses-free 3D projects, and investing resources to promote the progress of glasses-free 3D-related software and hardware technologies.

With the acceleration of urbanization, the continuous expansion of new commercial complexes, the vigorous development of the night travel economy in the post-epidemic era, and the comprehensive popularization of 5G+8K technology, the outdoor LED screen market has grown rapidly. According to statistics, it is expected that the naked-eye 3D market will reach 13.8 billion yuan in 2023.

In the past five years of development, creative display has become closer to life, and also closer to various high-tech technologies. It seems that not only the hardware of the right-angle screen has developed, but also in naked-eye 3D technology and ultra-high-definition video 4/8K technology. There is a breakthrough.

In the past five years, while maintaining the continuous technological progress, the LED display industry has also ushered in rapid development under various favorable policies. The brilliance of LED displays at this year's Beijing Winter Olympics is enough to show that the LED display industry has a new look!
