The LCD has been overshadowed by its performance in command and control centers since the small-pitch LED display entered the indoor space. With its high color gamut, high brightness, seamless splicing and other advantages, small spacing LED display rapidly expands in the field of command and control, once became the favorite of command and control center. Moreover, with the development of video control, power box and other third-party related application manufacturers, the application of LED display with small spacing in command and control center is more smoothly.

Small spacing LED display screen in command and control and other large indoor screen applications in the field of wanton expansion, so that once in this market DLP, LCD LCD mosaic dwarf, showing a stand of who I am. It is precisely the rapid development of small spacing LED display screen, so that the market application of LED display screen continues to expand, so that many LED display screens taste the sweet spot, and further promote the prosperity of small spacing LED display market.

In technology, small spacing not only develops toward more high-definition display, but also moves towards intelligence and standardization. In this process, the ghosts, mosaics, crosses and other problems that existed in the past with small spacing have been conquered. The application of LED display in commercial display field has been highly expected by LED display manufacturers and has been laid out one after another. In order to further expand the market and improve the display effect of small spacing LED display screen, LED display enterprises spare no effort, not only in the technical aspects of continuous improvement, and even began to introduce HDR technology.

However, no matter how small spacing LED display develops and how hard LED display manufacturers make efforts, it can not avoid two pending problems: first, with the shrinking spacing of points, the enormous technical challenges faced by its technology, such as the unavoidable dead-light problem as a discrete display device; second, the resulting problem. Cost growth. Despite the fact that some manufacturers have claimed to be able to mass-produce small-spacing LED displays (P0.8), the technical and cost problems that lead to small-spacing LED to the ceiling will be a real issue for display manufacturers. In order to solve this problem, the birth of COB small-space display screen, it seems that there is a lot of "situation hero" scent. Generally speaking, COB packaging is more advantageous than SMD for longing for ultra small spacing.

Since the beginning of this year, the discussion on COB display has never stopped. For the development of COB display, the industry is also different. Now, after more than half a year of development, the performance of COB display screen, especially small spacing COB display screen in the field of command and control, has once again aroused the attention of the industry. Among them, Lehman's COB display is becoming the focus of attention.

Lehman COB small spacing

Since Lehman announced the appearance of the third generation of COB display panels, Lehman has been constantly moving in the field of COB small-space display panels, not only at exhibitions at home and abroad, a variety of platforms on the frequent release of COB display related information, its application to the market has never stopped, a COB small-space display projects appear in the public In front of. For example, the Lehman small space COB high-definition display screen was installed in its exhibition hall by a well-known enterprise in London, UK, formally settled in the international metropolis London; recently in Shanghai Jiushi Public Transport Group Co., Ltd. intelligent analysis and command center successfully installed and put into use; installed in Shanghai Fengxian Parking Industry Development Co., Ltd. The successful application of these COB small spacing display screens in the control hall, such as the Lehman photoelectric small spacing COB high-definition display screen project and the COB small spacing display screen project of the command center of Qingxu County Public Security Bureau in Shanxi Province, has encouraged people to pay more attention to the market of COB small spacing display screens. Recently (August 8), Lehman and Shanghai Westview Technology Co., Ltd. signed a strategic cooperation agreement in Shanghai, on the next three years in the small space COB high-definition large screen cooperation reached an intention of strategic layout, but also let many people pay more attention to the small space COB display unprecedented.

For the COB display which has been labeled as "the future of small spacing" earlier, this wave of Lehman COB small spacing and future layout, but also to the COB small spacing display of the future development prospects add a few footnotes.

Compared with many traditional LED display manufacturers, Lehman's small-space COB display will become a strong "competitor". In the field of command and control alone, the traditional SMD small-spacing LED display is now in the spotlight. Many traditional LED display enterprises are trying to break through the "ultra-small-spacing technology" of 1.0 and below spacing, and constantly improve their product performance.

However, the COB small spacing in the command and control field of the strong march, indeed invisible to the traditional small spacing LED display has brought pressure. Even more people believe that small spacing based on COB has higher reliability, ultra-low breakdown rate, high efficiency protection, wear resistance, pressure, anti-collision, waterproof, anti-static advantages, so some people in the industry predict that small spacing LED industry will eventually enter the "COB era".

So what is the future trend of COB small spacing displays and traditional small spacing LED displays? Who will become the mainstream?

It is generally believed that the development of COB display screen has a certain impact on the current industry's ecological system. After all, COB is essentially a packaging technology, which means that the manufacturing of small spacing LED displays is focused on packaging. It is precisely for this reason that the current mainstream LED display enterprises are not very happy to promote COB, generally wait-and-see attitude.

About the traditional SMD small space display and the COB display screen, in fact, each has its advantages and disadvantages, SMD small space although there are dead lights and other issues, but COB is not the existence of uneven ink, maintenance problems?

Some people in the industry also believe that SMD small spacing LED display and COB small spacing display is a competitive relationship, currently in the "narrow road meet the brave win" situation, but in my view, the two are not in the "replacement and substitution" relationship, but each has its own market demand.

At present, SMD small spacing LED display still has a lot of room for improvement, and COB small spacing display may be the direct competitor in the future is Mini LED, that is, there is a lot of room for development in ultra-small spacing. In addition, COB has more advantages than SMD in anti-collision and waterproofing, so it will have a bright future in the outdoor display market.

Different LED display manufacturers have different views on the two technical routes, but almost all of them will make a prediction in favor of their own technical routes. Moreover, in order to win the competition, it is bound to increase the upgrading of its own technology and technology, increase investment in product applications, in order to occupy a larger market share.

However, it will take time to verify which side will dominate the market in the future for SMD small-spacing LED and COB small-spacing displays. But no matter which technology, it is an exploration of China's LED display and a direction of development.
