Domestic small-pitch LED display industry status and application trend analysis report

The small-pitch LED display is an integrated system, and only with the cooperation and cooperation of various small systems can the best display effect be achieved. From the analysis of the small-pitch LED display industry chain, the most critical part is the packaging device. Currently, major international manufacturers such as Nichia and Cree are still in a wait-and-see attitude towards light source devices below P2.5. There are already two companies in the mainland and Taiwan involved in the R&D and sales of small-pitch LED devices. Everlight Electronics is the first manufacturer to launch small-pitch devices. Currently, small-pitch products account for 5% of Everlight Electronics' total revenue. Its small-pitch LED devices were first cooperated with Leyard, with a yearly demand of 1,000KK. Since 2013, Everlight Electronics’ small-pitch LED lamp beads have not only been supplied to Leyard, but have been opened to small-pitch device manufacturers; Nationstar Optoelectronics currently has three small-pitch devices, of which the most mature 2020 is the mainland version launched in 2009. The first small-size device; and launched the higher-density 1515 device in 2012. In 2012, it began to develop the higher-density small-size device 1010 in CHIP type packaging. After one or two years of R&D and market testing, 1010 has now been put into mass production. , and vigorously promote it in the market; Taiwan Hongqi launched small-pitch packaging products in 2013, and the packaging specifications have been advanced to 0606 from 2020, and smaller-sized 0404 products are also planned. Hongqi currently applies LED small-pitch packaging models in three specifications: 2020, 1010 and 0606. The 1010 product has a high market share. Application manufacturers such as Shanghai Sansi, Lamp Technology, Unilumin Technology and other powerful manufacturers are using Hongqi 1010 products. Jingtai Optoelectronics launched the first generation of 1010 products in 2013 after R&D and practice. Because at present, 1010 products are the most controversial in small-pitch devices, such as caterpillars, dead lights, and failures. It can be said that the structure and reliability of 1010 products still need to be improved. In order to solve this problem In response to these problems, Jingtai Optoelectronics launched the second-generation 1010 product in 2014, which greatly improved the performance of the 1010 product. Currently, the monthly production capacity has reached 150KK while ensuring product quality, and the market response has been good. Leyard, Unilumin and Absen have become major application customers.

In addition, the development of small-pitch LED displays has also driven the development of related supporting facilities, such as the innovation of LED video processors, driver ICs, control systems and other products. In the driver field, Macroblock Suzhou Riyuecheng has launched small-pitch driver IC products. Macroblock and Hongqi have jointly established Xinrui Precision to jointly develop driver ICs for small-pitch products, hoping to expand market share through more complete solutions. North Incorporated and Leyard also jointly develop driver chips; in control and video processing systems, Xinrui Precision Both Anova and VioVideo have done corresponding research and development on small-pitch LED display control systems, and have products on the market. Special mention is that VioVideo's 86XX product specifically solves the problems of multiple signal sources, multi-channel outputs, and multi-image switching in small-pitch LED displays. This solution was recognized in a project in Singapore that was jointly constructed with Leyard.

Furthermore, at the end of the industrial chain, such as cabinets, kits, power supplies, etc., there are specialized products to support the development and application of small-pitch LED displays. From the analysis of the industry chain, the small-pitch LED display itself has a fairly mature industrial chain system, so the small-pitch LED display has inherent advantages from the beginning. These acquired deficiencies require cooperation among all links in the industry chain to complete.
