The data shared by the small space and MiniLED show show that Chinese mainland’s small pixel pitch spacing LED display market has sales volume of 6 billion 840 million yuan and sales volume of 109 thousand square meters. Cob small space market accounts for 5.9% of the overall market share of small space.
What are the technical problems of cob small space packaging standing on the industrial tuyere? What technological innovations have been made in the industry?
Through the experts to answer four questions, you can understand the technical difficulties of cob small spacing packaging.
1. Which cob technologies can play a good role in the era of miniled / microled?

After released cob products with small spacing, cob products with small spacing became hot. Many manufacturers launched cob products one after another, forming a trend of “no cob, no joy”. According to AVC data, cob products increased from 3.7% in 17 years to 4.1% in 18 years according to the distribution of different technologies in domestic market of small spacing led; According to the distribution of sales volume of different technologies in domestic market, cob products increased from 3.3% in 17 years to 5.9%.
So far, it can be seen that the early marketing and cultivation of cob products have been effective, and the recognition of the end market has changed significantly.
From Lehman’s point of view, led micro display is also cob technology. At present, cob front mounted small spacing and inverted Mini led small spacing and micro LED are actually integrated and packaged with LED chip and substrate. So, as you said, cob small spacing display technology can be directly applied to LED micro display, especially most cob small spacing display technology can be directly applied to mini LED display. At the same time, it also lays a solid foundation for the future 1000ppi HD micro led.
From our point of view, the following cob technologies can be better applied to mini led and micro LED display technology.
The above is our understanding of the intersection of cob small space technology and micro era technology. In miniled display, from cob substrate technology to production online maintenance technology, cob small spacing technology can provide a good technical foundation for miniled display. In the era of microled display, cob chip light color consistency technology and integrated packaging high reliability technology can also play a key role.
Lehman predicted that cob display technology will become the mainstream of LED small spacing high-definition display within three years, and gradually penetrate into commercial display and civil display, gaining more market space (more than 50 billion). This trend will change the division of labor pattern of LED small space display industry chain, and the midstream packaging enterprises and downstream display enterprises will merge into one.
Cob display technology is the deep integration of packaging technology and display technology. This change will reduce the manufacturing process and merge the two profit links. Meanwhile, cob small spacing products have the advantages of cost and quality life, and only cob can meet the requirements of Ultra HD quality with spacing below p0.9. Cob small spacing is also the only mature and mass production technology below P1.0, Therefore, the pure display lamp bead packaging enterprises and pure SMD small spacing display enterprises will be gradually marginalized, and the enterprises with deep packaging technology and display technology accumulation will be out of business
