In recent years, the rapid development of science and technology has injected new vitality into various fields. In the field of LED display technology, BPIPack technology, with COBIP (Chip On Borad Integrated Packaging) technology as the industry leader, is using its unique design concept and excellent performance Become a leader in future industries.

Introduction:

With the passage of time, LED display technology continues to evolve, and the rise of integrated COB technology has brought a breath of fresh air to the LED direct display industry. Its unique design concept aims to systematically redefine LED packaging technology, abandon traditional brackets and pins, and achieve highly integrated packaging of bare LED chips and driver IC chips, becoming a new benchmark in the industry. The reason why we want to engage in BPIPack technology is that we have made an important discovery in the process of integrated COB industry technology practice: "The reliability of the LED display panel has an important correlation with the number of bracket pins of the packaged device. To If we want to completely solve the problem of excessive failures of LED display panels, the best proactive solution is to remove the bracket pins from the packaging technology. The more thoroughly the bracket pins are removed, the better the panel failure problem will be solved."

Distinctive technical features:

The reason why integrated COB technology has attracted much attention is that its core lies in actively removing the brackets and pins of LED packaging devices and driver IC packaging devices, realizing the integration of lamp drivers on one PCB board or the integration of lamp drivers and pixels in one PCB. highly integrated packaging. This unprecedented design innovation not only improves the performance and reliability of LED displays, but also opens up wider possibilities in various application scenarios.

Original companies focus on bottom-level breakthroughs:

Integrated COB technology was founded by Wei Qiaoshun Optoelectronics in 2010. At that time, the traditional COB technology in the industry was still at the level of device-based COB technology. In the face of new technologies, packaging companies generally believe that it is an impossible industrialized technology. The reason is that the packaging process is too complex and cannot get rid of the problem of first-time pass rate.

After more than ten years of hard work, it seems that it is impossible, so why can it still continue?

lIn 2019, after three years of in-depth and systematic research on integrated COB technology, systematic classification ideas and methods for packaging technology were proposed, forming a systematic theoretical idea of BPIPack technology. Based on this idea and within the system technology framework, the second generation technology integrated COC product of this system technology was developed. Compared with the semi-pin removal technology of the first generation integrated COB, the goal of full pin removal is achieved.

This year, it also developed an integrated COB vehicle rear window transparent advertising sticker product, and has more than ten mature product solutions.

The scale of industrial development is gradually expanding：

So far, the industrial capital invested in integrated COB fine-pitch display products has far exceeded 10 billion. According to news from major platforms and summit forums in 2023, the industrial scale of integrated COB fine-pitch products is expected to exceed the industrial scale of traditional technology fine-pitch products.

Key ten years for industry development：

2020-2030 are the most critical 10 years for the development of the LED direct display industry. The landmark and epoch-making event in 2020 is that the "General Technical Specifications for Mini LED Commercial Displays" T/SLDA01-2020 adopted the group standard It is recommended that LED display panels should be classified according to packaging system technology: in the group logo, Mini LED commercial displays appear based on bracket pin type single device packaging lamp driver separation system technology and bracket-free pinless integrated packaging lamp driver system Classification representation of technology. The genetic evaluation index of the underlying technology of Mini LED display screen, the pixel out-of-control rate has increased from 10,000 levels to 1 million levels. Integrated COB technology, as the primary form of bracket-less leadless integrated packaging system technology, has led the decade-long transformation of industrial technology from separation to integration with the advantages of systematic technology demonstrated in fine-pitch displays. Road, ten years is the overlapping transition period of the two system technologies, and it is also the golden period for the transformation of industrial technology from low-end to high-end. In the first half of the decade, there is no doubt that the industrial scale of integrated COB fine-pitch display products will surpass that of traditional technology fine-pitch display products. Driven by its influence, integrated COB technology products will have a sinking influence. And iterate the traditional outdoor display and traditional technology display market. In the second half of the decade, integrated COB technology will continue to open up more new application areas, such as AR/VR, driverless driving, vehicle-mounted optical information interaction, smart home appliances and homes, wearable displays, and stickable displays. , portable intelligent connected splicing display, offline green energy energy-saving display, rolling shutter display, drone stage design and high-altitude 3D display and other military and civilian fields. As the scale of the industry continues to expand and the speed of iteration accelerates, exponential changes may occur.

Welcome the arrival of the post-COB integration era：

After 2030, the industry iteration will be basically completed, and the industry will enter the post-COB integration era, when BPIPack technology will be deeply rooted in the hearts of the people. Once we enter the post-COB integration era, with the further improvement of equipment and process technology capabilities, and the continuous advancement of materials, wireless communications, light-sensing micro-power supply and other technologies, we believe: "There should be at least two X technologies that will be used without brackets." By eliminating pins and integrating them into the light driver + It's no longer a dream.

End of year message：

The rise of bracketless leadless integrated packaging technology marks a new chapter in LED display technology. As a member of the industry, we are well aware of the importance of this innovation, so we should take it seriously and contribute our strength to a more brilliant future for LED display technology through continuous efforts, innovation and cooperation.

Please think carefully about the profound meaning of "packaging technology without brackets and pins", it will become an endogenous driving force for your future development. Catch up with the trend, even if it's drifting with the wind.

Let us welcome a better and more challenging 2024 together!
