The exhibition brought together the latest products of LED display, LED advertising light source, LED lighting, LED chip packaging, LED equipment, digital signage, laser engraving equipment, acrylic sheet, POP, digital printing design inside and outside, printing consumables and so on. solution.
Although there are not many exhibitors at this exhibition, such as Liard, Powerful Jucai, Chau Ming Technology, Guangxiang Technology, Ralink Display, Mai Rui Optoelectronics, Qipu Optoelectronics, Baco Optoelectronics, Xida Electronics, Dongshan Precision, Carnet, sporadic rain and many other well-known domestic and foreign manufacturers have appeared on stage.
It is worth mentioning that the major display manufacturers on-site showcase their small-pitch products that they are proud of. From the products displayed by the various products, SMD light source small-pitch display, COB small-pitch display and four-in-one light source small-pitch display have become the main lines of technology development in the current industry.
For these three directions, many display manufacturers are COB small pitch stations. Li Yibing, Secretary of the Board of Directors of Shenzhen Baco Optoelectronics, said that although the current COB small-pitch market space is still not very large, after solving the problems of yield and processing difficulty, the future will become the mainstream of the display industry, which effectively solves the SMD light source. Short board with poor collision resistance.
Changchun Xida Electronics is one of the main forces to promote the development of flip-chip COB small-pitch display. It is reported that Hida Electronics' sales of COB display in 2018 has reached 280 million. In the industry's sluggish environment, it has continued to grow substantially against the trend. Currently, the monthly COB display has reached hundreds of square meters.

Currently, the monthly COB display has reached hundreds of square meters.
Lehman Optoelectronics is another manufacturer that promotes COB. The Lehman's 275-inch 4K small-pitch COB large screen and the M1.2 2K small-pitch conference TV exhibited by Lehman also received a lot of attention. It is understood that the current P1.5 and P1.2 COB displays have been mass-produced, and the P0.X series is also coming soon.
The industry has always believed that COB is easier to achieve small spacing. The COB package uses integrated packaging technology, which eliminates the need for a single LED device and then mounts the package. It can effectively solve the SMD package display screen, because the dot pitch is continuously reduced, the process difficulty is increased, the yield is reduced, and the cost is increased.
However, Mini LED has become a hot topic in the industry since 2018, both for packaging manufacturers and LED display application manufacturers have launched Mini LED products. Since the manufacturing process of the "four-in-one" Mini LED is almost the same as that of the traditional SMD, it has been favored by more and more display companies in the industry.
For example, Mini LED TV, which is displayed at Easycom, attracts many customers to watch the experience and inquire. It is reported that the TV supports HDR+HLG format, showing more complete image details through higher color depth input and more back-end grayscale processing digits.
Easystar Mini LED TV
Zhou Hualin, Director of Easystar Marketing, introduced to Gaogong LED: "Mini LED full-length TV wide color gamut, color temperature intelligently adjustable, through the easy-to-accurate precision correction technology, greatly improved the corrected color gamut, up to 110% NTSC And very energy efficient, with dual voltage drive, can save 50% energy consumption under the same brightness conditions."
In addition to EasyCard, Zhouming Technology launched a new generation of small-pitch LED display products - 4K Mini-LED0.9 at the exhibition site, which opened a new era of Mini LED display for batch application below 1mm.
From the scene of the exhibition, it can be reflected that Mini LED and Micro LED have become the battleground for major LED display companies. According to industry estimates, the Mini LED display application will be commercialized in 2019.
Compared with COB and Mini LED, traditional SMD LED small-pitch display, each company is mainly focused on product performance optimization. Such as the powerful giant color Q Pro small spacing using the standard universal 320 * 160mm display module size; will be upgraded to PWM-SS dynamic energy-saving drive IC, grayscale processing is more awkward, support 4V low-voltage start, dynamic information screen, more energy-saving , more power-saving; 4K high-definition high-brush display, photographing waterless ripple; can be matched with Magnolia cabinet, free DIY, separate installation, seamless splicing, complete front maintenance.
According to the powerful giant staff, the Q 1.25 Pro series of products are exquisite and exquisite, showing the details to the fullest, making people linger, has been widely used in high-end conference rooms, studios, exhibition halls, government departments, etc.; and Q1.25 Pro The same boutique Q1.53 Pro, the unique point spacing design, is deviating, and there are more points per unit area.
Powerful giant booth
In this exhibition, the powerful giant color is based on the multi-application of small-pitch LED display, which perfectly interprets the charm of the small-pitch LED screen, fully demonstrates the strength and style of the big brand in the LED display field, and has won the unanimity of domestic and foreign customers. Praise.
In fact, the industry debate about who will become mainstream technology for SMD, COB and Mini/Micro LEDs has always existed. In this regard, Tang Jianping, general manager of Decolor Optoelectronics believes that the three will coexist in the future. He said that the emergence of any technology will drive some new applications and markets. Overall, the LED display market will become a big cake.
For the future trend of the LED display industry, EasyCard Zhou Hualin believes that it will mainly be reflected in two aspects: one is that the dot spacing of the display screen is getting smaller and smaller; secondly, the Mini LED will be a future development direction, which passes With HCC plus four-in-one technology, durability is much improved. In addition, in the field of application, it may be oriented to various industries, such as new retail, public transportation, security monitoring and so on.
