COB is the only way to Micro LED. COB outdoor display welcomes new opportunities
When it comes to the future of COB and MIP, Ji Fengqiang expressed his own opinions. He believes that MIPs on the market are currently divided into two categories: package level and chip level. Package level MIP is represented by Jingtai, Lijing, etc., and is still an extension of the SMT process. Chip level MIP is dominated by international brands such as Seoul Semiconductor and Samsung. The difference between package-level MIP and COB is actually the difference between SMT and COB packaging processes. COB has an absolute leading advantage in terms of reliability and stability; at the same time, because COB does not have a lampIn the cup packaging process, the Chip is directly mounted on the Board. Under the same scale, the COB cost is much lower than the packaging level MIP. The main battlefield of package-level MIP is in the field of Mini LED. Its products are mainly used in commercial displays, XP photography, consumer fields, etc., and are not suitable for professional applications such as government and medical. Its spacing is limited, and it cannot fully enter the Micro LED field. Therefore, package-level MIP is only an extension of the original capabilities and a continuation of the industry cycle. It does not represent the future, let alone a broad future. Chip-level MIP is essentially a change in the arrangement of RGB chips. Its process is still solid crystal or mass transfer, which is basically consistent with the future technology path of COB. However, because its cost is too high and mass production capacity cannot be guaranteed, it is still difficult to achieve batch supply in the short term. Until the industry technology, manufacturing costs, production equipment and other dimensions are unified and mature, the Micro LED field will remain parallel to COB until the market and users make the final choice. COB will be the mainstream technology of Mini LED and the only way to Micro LED.
Compared with traditional displays, COB displays have significant advantages such as high reliability, high protection, high brightness, high contrast, and high color reproduction. Moving from indoors to outdoors means that it will bring a visual experience of higher picture quality and product quality to outdoor display applications. It is a new upgrade in performance for the traditional outdoor display market and is also a high-quality product that conforms to the outdoor display market.The inevitable change of the growing trend of quality demand.
Ji Fengqiang also said that the outdoor environment is complex and changeable, which places extremely high requirements on the durability and protection of the display. Therefore, COB displays require higher protection to ensure that they can operate stably in harsh outdoor environments. Outdoor displays usually require higher brightness to cope with long-distance viewing and strong light exposure, which requires achieving higher brightness and low power consumption to save overall operating costs while ensuring display effects. The display screen must also have high reliability and convenient installation and maintenance methods. First, it has a low failure rate after long-term use. Second, it is convenient to install and maintain, reducing installation and maintenance costs. System operation capability is also an important factor to ensure longer transmission distances and more stable signals. In addition, for COB displays to enter the outdoors, further breakthroughs in UV technology, material systems and production processes are needed. It is believed that with the continuous progress and maturity of COB technology, in addition to the traditional indoor application requirements, the door to the "new outdoor track" of COB technology will be opened in the future.

Since 2023, the price of COB LED has continued to decline, which is a double-edged sword for the industry. Ji Fengqiang believes that on the positive side, the decline in prices has promoted the popularization of COB technology and broadened its application fields, allowing more consumers and enterprises to access and adopt this cutting-edge technology, thereby promoting the market share of COB. However, looking at it from another perspective, the continued decline in prices may also lead some companies to pursue profits and excessively reduce costs, which may lead to quality hazards and damage the reputation of the industry. Therefore, Xida Electronics calls on its peers to maintain a rational development attitude and return to a healthy competition model. We should work together to improve product quality and technical level, and conquer the market with the hard power of science and technology. Only in this way can we bring a better product experience to consumers and ensure the sustainable and healthy development of the industry.
The future development trend of COB technology is still rapid.
