Who is the next profit growth point for COB?
As a new type of packaging technology, COB directly replaces the two-step process of “the surface-mounting process is first packaged into a lamp post and surface-mountedâ€, which brings more space and more possibilities to the LED display industry. At the same time, it has also attracted a large number of enterprises as strengths. Domestically, there are several companies such as Lehman, Hida and Abisen. In the future, will the COB market become the main battlefield for LED small-pitch screens? COB small spacing came into being In the field of LED display, with the development of upstream packaging technology, three different LED display panel preparation processes of LAMP, SMD and COB have been gradually formed in the industry. Before the advent of COB products, SMD products were the absolute “overlord†for indoor small-pitch LED applications, the only choice in the market. In this situation, technically, the user can choose only the difference in dot pitch. However, as the first generation of small-pitch LEDs, SMD products have also revealed obvious deficiencies due to the inherent light-emitting principle and packaging process defects. “Bad lamps continue to accumulate, viewing comfort is poor, and protection performance is weak. "The problem has been plaguing the industry and users. In the context of continuous upgrading of customer needs, the point spacing should not and can no longer be the only standard that users can choose. A more stable system, a better picture, and a healthier display can “cast†the long-distance market competition of small-pitch LEDs. ability. As a result, the small spacing of COB has emerged as the times require, both in terms of technology and market structure, which will profoundly affect the development of the entire small-pitch LED industry. COB technology directly encapsulates the LED chip on the PCB board, effectively solving the problem of reliability and protection of small-pitch LEDs, and the accumulated dead point rate is less than one tenth of the traditional SMD technology. In terms of adaptability to the environment, COB has the functions of moisture-proof, anti-static, anti-collision, dustproof, etc. The front protection level reaches IP54, which is recognized as the development direction of small-pitch LED technology in the industry. The COB small pitch technology has also been listed as a major topic in the strategic advanced electronic materials field by the National 13th Five-Year Plan. Reasons for high reliability of COB process Giants compete, COB iterative acceleration In recent years, COB display technology has gradually gained market recognition. At 2018 ISE, there are also P1.5 Pitch COB products from China Lehman Optoelectronics, and new industry giants such as Abbison COBALT technology and US-listed Dako Electronics COB display products are participating in this technology product competition. International giant Samsung also demonstrated COB-based small-pitch LED products in CES in the United States in 2018 and ISE in the Netherlands. At the same time, LG also reported that it will launch the first Micro-LED TV in September this year, which is also a COB small-pitch product category. At the previous LED exhibition in Guangzhou, Huaxia Guangcai released MINI COB small pitch products. At the same time, Liard also said on the interactive platform that the company is currently developing COB-type Mini LED small pitch products, using Mini LED die as display pixels. Inverted mode COB is used for process processing, and small batch trial production is underway at this stage. More listed companies' blessings, in the "one big" camp of Chinese manufacturers, the global small-pitch LED display sector, the application of COB technology is steadily moving from non-mainstream to mainstream technology. In combination with the previous industry giants Sony, Witron, etc., entering the COB small-pitch market as early as 2016, and the continuous expansion of the COB small-pitch product brand in 2016-2017, the number of brands that can be selected for COB products in the domestic market in 2018 is likely to reach 10 -20. This is already a "very high number" for the small-pitch LED market, where market share is increasingly centralized. The industry expects that “continuous improvement of supply sideâ€, including “decreased cost under scale supplyâ€, “addition of marketable brandsâ€, “further rise of lyric support†and “a large number of demonstration projects†will inevitably lead to Iterative acceleration of COB technology products in the small-pitch LED market in 2018. From the perspective of market growth, COB products will be significantly higher than the entire small-pitch LED industry in 2018. From the absolute share, the proportion of COB in the small-pitch LED industry will also be “sit-and-see†and become the mainstream choice of the market. . The power to promote COB product upgrades in 2018 is not only the inevitability of technology and demand advancement, but also the strategic issue of corporate competition. Considering COB as an opportunity to overtake a corner, this is the "unspoken" tactic of many small-pitch LED companies. The realization of COB products in 2018 will even become the "starting point" for changing the brand share pattern of the small-pitch LED screen industry in the next three to four years. What is the next profit growth point for COB? The emergence of COB technology has alleviated the serious dilemma of small-pitch homogenization, bringing new possibilities to the development of small-pitch, and opening up a broader HD display market for LED display products. It can be said that it is the most valuable in the industry. One of the breakthrough directions. Now many companies in the industry are waiting to see and deepen COB technology and products. I believe that with the further maturity of technology and the realization of mass production, the future of LED display must be the home of COB. According to the relevant analysis report of Soochow Securities Research Institute, in the future, COB shows a wide range of application scenarios in small-pitch LEDs and large-scale commercial display fields: 1) In terms of small-pitch display, current COB technologies and products are in the field of small-span LEDs. Leading products, less competition, is the industry's blue ocean; 2) Large-scale commercial display, COB can bring greater value to commercial lighting, far beyond the performance of ordinary LEDs for products, Samsung and other LED display faucets are The field is fully deployed.
