In recent years, the application of COB (Chip-on-Board) technology in the field of LED display has gradually attracted attention. The general consensus in the industry is that COB technology has become a major trend in the development of the LED display industry. According to the latest data from Experts Research, by 2025, the planned monthly production capacity of COB is expected to exceed 80,000 square meters, showing the strong potential and growing recognition of this technology in the market.
2023 is a challenging and critical year for COB, but with the continued growth of technological innovation and market demand, COB's production capacity has reached 50,000 square meters in 2024, and is expected to grow to 51,000 square meters by the end of the year. This data undoubtedly lays a solid foundation for future development. In the small-pitch LED display market, especially for P1.2 pitch products, COB's penetration rate has increased to more than 60%, and its performance in the P1.5 and P0.9 markets is also positive, showing strong market demand. Its rapidly growing shipments further prove the market acceptance and competitiveness of COB technology.
As an emerging display technology, COB has higher integration and better display effect than traditional SMD (surface mount device) technology. The core advantage of COB technology is that it can achieve smaller dot pitch, thereby improving image clarity and display quality. According to the latest data, COB technology has made significant progress in the application of different dot pitches, among which the market share of P1.2 pitch has reached 60-70%. This change has brought new opportunities to the high-end display market, especially in occasions with high requirements for visual effects, such as commercial displays and stage performances.
At the technical level, COB's innovation is mainly reflected in its higher production efficiency and lower material costs. With the participation of more manufacturers, 16 companies have been put into production in this field in 2024, among which Zhaochi Jingxuan and Zhongqi Optoelectronics are important promoters in the industry. The combined monthly production capacity of these companies has reached a significant scale, providing a stable supply for the entire industry chain. At the same time, manufacturers are also constantly seeking technological breakthroughs to improve product quality and yield, and ensure that they are invincible in the increasingly fierce market competition.
In addition to the expansion of production capacity and market scale, the improvement of COB technology in user experience cannot be ignored. Using advanced AI technology, these displays can provide smarter management and control systems, improving the consistency and stability of display effects. In addition, with the widespread application of artificial intelligence in content generation and processing, COB technology will also be deeply integrated with emerging technologies such as AI painting and AI writing to improve creative efficiency and content expression.
Despite the strong development momentum of COB technology, there are still many challenges in the future. First, the cost-effectiveness balance of large-pitch applications is still an urgent problem to be solved; second, the development space of the market below P1.0 has yet to be clarified; third, the competitive pressure from other technologies is also increasing. Therefore, in order to achieve higher production capacity and market share in 2025, the industry needs to continue to innovate and upgrade technology, especially in the construction of the ecosystem and the deepening of cooperation in the industrial chain.
In summary, the development of COB technology in 2024 showed significant advantages. It not only achieved results in innovation, production capacity and market recognition, but also led the technological progress of the LED display industry. Looking to the future, with the maturity of technology and the expansion of the market, COB will surely play an increasingly important role in the LED display industry and continue to promote the transformation and upgrading of the industry.
