How to expand the LED display market with GOB technology and products, the dark horse in the industry?

The giant wheel of history is rolling forward, and the LED display technology has always been in the ascendant, and a rookie is emerging. Even though LED display technology has developed for a long time, there are still pain points that need to be improved. Taking waterproof performance as an example, even if the IP rating exceeds 70, it can only reduce the failures caused by rain erosion, and cannot solve the waterproof problem from the root. Based on this problem, a new type of surface super-protection technology called GOB came into being on the market. With its high-performance protection technology and delicate display effect, it has quickly been recognized by the industry in just a few years and has become the LED display industry. In the past two years, the new generation of technology has attracted many companies to join the GOB technology industry, develop and produce a new generation of GOB products, and expand the protection market for LED displays.

Originated from industry pain points, attributed to market demand

At present, the most widely used LED display is the traditional SMD surface mount process, and the COB technology products launched in recent years. As the dot pitch becomes smaller and the application range becomes wider and wider, the problems existing in SMD and COB are also magnified, which becomes the room for improvement of the current LED display. From a technical point of view, SMD technology uses a high-speed placement machine to weld the lamp beads on the circuit board with high-temperature reflow soldering to make display units with different pitches. However, since the lamp beads and pins of SMD surface mount products are exposed, once bumps or vibrations occur, it is easy to cause the lamp beads to fall off and fail; in addition, water, moisture, oxidation and other problems in the use environment will easily affect the product. Precision devices can easily lead to failure of lamp beads, large areas of dead lights and broken lights, which lead to abnormal use of products and a significant decrease in service life. In addition, the SMD process needs to add a mask to protect the lamp beads, but its protective performance is very low, and when the mask is used in a high temperature environment, it is easy to cause the mask to bulge, yellow and white, and affect the LED display. overall perception. Even the SMD technology, which has been used for the longest time, still has pain points that need to be improved.

Another technology, COB, is derived from the deepening of small-pitch LED displays, and the cost of SMD technology applied to small-pitch increases with the reduction of dot pitch, and there is a certain existence of SMD applied to display screens with a dot pitch below 1.0mm. technical difficulties and other pain points, and after years of research and testing, it has been successfully applied to LED displays. Therefore, from the analysis of technical theory, COB technology is advanced and feasible, but because there is no lamp selection process in the early stage, it cannot be separated into light and color after packaging, and the modularization is serious and the consistency is poor; The technical difficulty is high, and the maintenance difficulty is also relatively high. Generally, it needs to be returned to the factory for maintenance, which leads to maintenance difficulties and high maintenance costs. Due to the above-mentioned reasons, COB technology has not been widely promoted and applied at present.

Based on the problems of the above two technologies, the industry proposed the concept of GOB technology in 2017, expecting to integrate the lamp bead and PCB board based on the traditional and mature SMD process, so that the two are highly integrated and form a solid surface on the product surface. protective layer to achieve super protective performance and high-quality display effect. The first batch of GOB pioneer companies know through practice that GOB technology is feasible, so the first batch of GOB companies launched the first generation of GOB products. Based on the market’s feedback on the first-generation products, as well as the problems encountered by the company itself in the process of R&D and production, GOB companies have upgraded and optimized the GOB technology. Today’s GOB technology uses a new type of high-factor optical and heat-conducting nano-filling material. After a special process, the PCB board of the conventional LED display and its SMD lamp beads are integrated and packaged and the surface is optically treated to achieve waterproof, moisture-proof, anti-collision, anti-oxidation, etc. from the root. The effect completely solves the problem of SMD technology protection performance; the surface optical treatment technology enables the display screen to realize the transformation from point light source to surface light source, making the light more uniform and soft, the display effect more clear and transparent, and greatly improving the viewing angle of the product; The surface of GOB products adopts a matte effect. The matte surface can improve product contrast, reduce glare and glare, and reduce visual fatigue. However, it is not easy to mass-produce GOB technology and products with excellent quality and recognized by customers, especially small-pitch GOB products.

According to Wang Yongqiang, the general manager of Qiangyi Technology who was involved in and in-depth research and development of GOB technology earlier, GOB technology with exquisite workmanship, mature technology and reliable quality and product requirements for packaging materials, mastering the maturity and reliability of production technology, and cooperating with independent production Non-standard customized automatic production equipment for the process, refined mold making tools, and the realization of precision standards are indispensable. For example, packaging materials are customized and developed to meet various characteristics such as adhesion, tensile impact resistance, hardness, transparency, wear resistance, high and low temperature resistance, yellowing resistance, and repairability; such as technical processes, it is necessary to ensure the smoothness of glue filling. The thickness of the glue layer on the surface of the lamp bead should be uniform after packaging, and the tolerance should be controlled at 0.1mm, exceeding 0.2mm. The black screen and the light on the screen will cause modularization, blurred screen, uneven splicing, A series of fatal problems such as poor consistency and so on. With the continuous development and improvement of GOB, its technology and products are in a mature state, so it can be quickly applied to the market and gained market recognition in just two years.

Wide range of applications and broad market prospects

Since the launch of the first generation of GOB products in 2017, through the continuous exploration and application of GOB companies, some companies have been able to mass-produce the third-generation COB products, and the technical solutions of the fourth-generation products have also been successfully reserved. The development of GOB technology in two years is quite rapid. According to industry insiders, there is actually a one-year gap between GOB 1.0 products and 2.0, but after the continuous promotion and popularization of GOB technology and products by GOB companies, the industry awareness of GOB technology and products has gradually increased, and the recognition of GOB technology There are more and more people in the industry related to products, which drives the market demand for GOB products to rise. The difference between GOB product 2.0 and 3.0 is only half a year, and the company has lowered the dot pitch to 0.9mm, which proves that GOB technology can be applied to small-pitch products or even Mini products, expanding its market in small-pitch products. Under the condition that the 0.9mm dot pitch display can meet the current viewing needs of people, it can solve the pain points of SMD products, and the GOB products, whose cost is lower than that of COB products, are more competitive in the small-pitch field. As the demand for small-pitch products in the field of security and video conferencing expands, with the further improvement of GOB products and technologies, GOB products will also have a broader market in the field of small-pitch products. The advantages of GOB technology in terms of waterproof, dustproof, weather resistance and other protective properties, coupled with the characteristics of GOB technology, can make the application of outdoor smaller spacing (below P2.5) a reality. GOB products can be applied to scenarios such as outdoor advertising display, smart light poles, outdoor rental, and creative display, improving the clarity of outdoor display and expanding the scope of application scenarios.

In this year’s two sessions, the country puts new infrastructure on the national development key strategy, focusing on the development of new infrastructure, and the seven major areas of new infrastructure are closely related to high-definition display, which is a once-in-a-lifetime opportunity for the LED displays of the three major commercial displays Opportunities, and for mature GOB companies with strong scenario applicability and the ability to solve industry pain points, it is also a rare opportunity to expand awareness and increase market demand. Therefore, GOB products can also show their talents in the new infrastructure field and compete with other LED display products. To sum up, GOB products can be widely used in various application scenarios, and its market will continue to expand with the deepening of the LED display market, and will become another major application product in the LED display industry.

Although the application of GOB technology has only been for more than two years, with its mature technology, super protection performance, and high-quality display effect, it has quickly gained market recognition and promoted the increase in market demand. It is believed that with the continuous improvement of GOB technology and the continuous deepening and broadening of LED display application scenarios, future GOB products will become a major application trend in the LED display industry.
