It is not difficult to see from the 2017 performance report released by the major LED display companies and the new products launched. The small-pitch LED display is still the darling of the LED display industry and has an absolute dominant position in the market. However, after two years of blowout explosions in small-pitch LED displays, the phenomenon of product homogenization in the market has become more serious, and the industry has begun to enter the bottleneck of technological innovation. Recently, the breakthrough of COB packaging technology has injected new vitality into the small-pitch LED display market. All major LED screen companies have increased the COB small-pitch market, trying to occupy a larger market share and obtain the maximum enterprise benefits. At the moment of innovation and reform, can COB packaging technology lead a new storm in the small-pitch LED display?
The application of small-pitch applications continues to expand. Technological innovation is imminent.
The end user’s higher pursuit of product display quality and the continuous expansion of the application field are the fuel-burning agents for LED display manufacturers to accelerate the pace of product development, and promote the LED display industry to advance rapidly. The advent of the small-pitch LED display not only brings more high-definition and comfortable display effects to users, 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 are gradually adding LED display screens with large and small spacing, and the demand for each application field is increasing, in addition to the “mastery” tradition. Outside the fields of advertising media and Shangxian, with the rapid development of smart cities and safe China, small-pitch LED displays have also taken root in the mid- to high-end applications where indoor security, conference rooms and other economic needs are strong.
The continuous innovation of small-pitch LED display applications has led to higher requirements for products, and LED display companies have been unable to meet the diversified needs of the terminal market with only a new technology. Constantly updating and upgrading can enhance the competitiveness of the enterprise market and promote the rapid development of the industry.
COB shows unique charm, strong support for small pitch products
The mature application of COB technology leads a new breakthrough in LED small-pitch display technology. After continuous exploration and research and development, COB packaging technology has finally achieved breakthroughs in all aspects and has become the object of favor for all major enterprises in the industry. At the Guangzhou LED Exhibition in 2018, leading companies such as Ai Biesen and Huaxia Guangcai 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 packaging technology can be widely welcomed by manufacturers in the application of small-pitch display products, and it must have its unique charm. First of all, COB small-pitch LED technology is beneficial to the control of the dead-point rate under extremely small pitch and a large number of lamp bead conditions, and achieves higher reliability with less than one-tenth of the SMD surface-mounting process. The COB technology using the chip-scale packaging process essentially replaces the two-step process of “the surface-mounting process is first packaged into a lamp post-surface sticker”. As a more simplified engineering method, its cost change is more controllable under the same application scale, especially in the face of “smaller and smaller” pixel points; as a future development direction of LED display industry, small pitch products The smaller crystal particles are a promising proposition, and to integrate smaller LED crystal particles, it is clear that the COB packaging technology is more suitable than the traditional engineering route of “before the lamp bead post”. Under the background of the continuous decline in the price of mainstream surface-mount process LED products, COB technology has undoubtedly become a key “quality improvement” development point.
