2018LED small pitch technology innovation when looking at COB

Judging from the various signs that are available, 2018 is likely to be the year of COB packaging. The development of COB technology will also inject new vitality into small-pitch LEDs that enter the bottleneck of innovation, as the industry has said: "COB plays a leading role in the high-growth field of LED small-pitch HD display, which is of great help to promote the upgrading of LED industry products.

The reason why COB packaging technology can achieve a major market breakthrough in 2018, in addition to the long technical accumulation, but also depends on the promotion of many factors.

Technology, market demand

It proves that “the future of small pitch is COB”. With the stable and mature technology, COB small-pitch LED can bring a refreshing feeling to users, breaking through the competition of “smaller and smaller” in the past, COB. It has also become the best way to solve many small-pitch "stubborn diseases", such as the outdoor small-pitch packaging and the "graininess" inherent in LED technology.

On the other hand, the demand for higher-definition small-pitch LEDs in the terminal market is also promoting the development of COB technology. At the same time, for the entire LED display industry, different spacings will no longer be the only standard for LED display products. Different packaging technologies have become another key factor in distinguishing and selecting products.

Enterprise innovation

In fact, many screen companies in the industry have already forgotten the "Olive Branch" for COB. Since the second half of last year, companies such as Lehman, Changchun Xida, Weichuang and Wei Qiaoshun have accelerated their layout in COB technology, products and markets. Represented by Lehman, it has been actively exploring COB technology innovation since 2014. Since 2017, it has been in the overall layout of related technology patents to product innovation (third generation COB panels) for the COB market. The ignition has laid a solid foundation.

Industry chain drive

In addition to the company's own forecast of market prospects, the development of COB packaging has also benefited from the promotion of the entire industry chain: As we all know, domestic LED packaging and testing enterprises have entered a large-scale expansion cycle since the second half of 2015, and quite a few of them are new. The increase in capacity is arranged in the COB packaging technology. This is not only because of the accelerated development of COBLED display applications, including lighting applications, and backlight applications for TVs, but also into the chip-level packaging era of COB. Therefore, the entire LED industry chain from upstream wafer, midstream packaging to downstream applications And peripheral equipment and materials manufacturers are supporting the development of COB products.

Policy guidance

Not only that, in terms of national policies, COB technology also occupies the “time of day” – news from the Ministry of Science and Technology in September 2017: COB as the future development direction of small-pitch LED, won the national “13th Five-Year” key scientific research project— - Strategic advanced electronic materials • Funding for new display projects, the main task is to break through the shortcomings and limitations of traditional small-pitch LED display technology.

2017 is a year in which COB small-pitch LED products have changed from concept to product and engineering application. In 2018, from the previous international ISE exhibition and Guangzhou ISLE exhibition, more and more screen enterprises Spontaneously participating in the “faction” of COB packaging, the market is also showing a rapid increase (although the overall scale is still limited). The addition of Samsung, Daktronics, and ABBIS (COBALT technology) to the industry has given confidence in the COB packaging market. 2018, a number of packaging technologies, when looking at COB!
