Is COB LED display will be the future trend?

Recently, the breakthrough in COB Encapsulation technology has injected new vitality into the market for small-pitch LED displays. The major LED screen enterprises have oversized the COB small-pitch market, trying to occupy a larger market share and gaining the greatest business benefits. Then it is urgently needed in the industry. In the current period of innovation and reform, can COB Encapsulation technology lead a new storm in small-pitch LED displays? and is COB LED display will be the future trend?

COB LED display


Small space applications continue to expand Technology innovation is imminent

The higher end product users' pursuit of product display quality and the continuous expansion of their application fields are the fuel-burning agents for LED display manufacturers to accelerate the pace of product research and development, and promote the rapid progress of the LED display industry. The advent of small-pitch LED displays not only brings users more high-definition and comfortable display results, but also brings technological innovation to the LED display industry at that time. With the popularization of small-pitch LED display technology and the reduction of product cost, more and more manufacturers gradually increase the size and pitch of LED display inputs, and the demand for each application field is also increasing, in addition to “dominating” the traditional In areas such as advertising media and Shangxian, with the rapid development of smart cities, small-pitch LED displays have also occupied a portion of market share in high-end applications such as indoor security and conference rooms with strong economic demand.

The continuous innovation in the application of small-pitch led display screens has led to a higher demand for products, and LED display companies have only been able to reduce the distance between lamp beads and are unable to meet the diversified needs of the terminal market. Only new technologies are available. Constantly updating and upgrading can improve the market competitiveness of enterprises and promote the rapid development of the industry.

COB display unique charm strong help small pitch products

The mature use of COB technology has led to a new breakthrough in LED small-pitch display technology. After continuous exploration and research and development, COB Encapsulation technology has finally achieved a breakthrough in all parties and has become the target of the industry's major companies. At the Guangzhou LED Show in 2018, leading companies in the industry, such as Absen and Cathay Pacific, launched the newly developed COB small-pitch display products, which attracted a lot of attention from the industry and became a hot topic in the industry.

COB Encapsulation technology can be widely welcomed by manufacturers in the application of small-pitch display screen products, and it must have its unique charm. First of all, the COB small-pitch LED technology is conducive to the control of the bad spot rate under very small pitches and extremely large amounts of lamp beads, achieving a higher reliability of the product by less than one-tenth of the bad point rate of the SMD surface-mounting process; The COB technology using the chip-level Encapsulation process essentially replaces the two-step process of "surface-mounting the package into the lamp bead and the surface-mounting" directly with the package. As a more simplified engineering method, under the same application scale, especially when faced with “smaller and smaller” pixels, the cost change is more controllable; as the development direction of the future LED display industry, small pitch products The smaller crystal grains are not a proposition to bypass, and to integrate smaller LED crystal grains, it is clear that the COB Encapsulation technology is more suitable than the traditional engineering route of “first lamp bead rear surface mount”. Under the background of falling prices of mainstream surface-mount LED products, COB technology has undoubtedly become a key development point.

Fully break through product restrictions and lead the industry's new trend

With the popularity of COB technology and smaller pitch surface-mount technology products, small-pitch LED displays have entered the MINI-LED crystal era, and MINI-LEDs play a key role in COB and P1.0 surface-mount products. MINI-LED, COB, and small-pitch technologies combine with each other to form a new generation of MINI COB small-pitch screens. The MINI COB small-pitch screen successfully solves the problem of poor consistency of the common COB small-pitch display. The replacement of the module requires re-correction, and the on-site cannot maintain problems. Compared to the common COB small-pitch display, it successfully overcomes the high process requirements and professionalism. Strong cost, low yield, limited size, etc. After continuous improvement of technology, COB's small-pitch R&D costs will be further reduced. At that time, COB small-pitch products will spread the market and lead the industry in new trends.

Technological innovation is a constant topic in the LED display industry. Only by continuously introducing new technologies and new products can we ensure the successful completion of industrial upgrading. The emergence of COB technology, with a small pitch LED products to a higher level, to bring a better user experience for the end market, but we can not predict, there will be how sophisticated technology in the future waiting for the LED display The screen industry will bring surprises to users, let us wait and see!
