Small Pitch LEDs, Can You Do More Small?

- Mar 30, 2019-

According to the latest data from the High-tech Research Institute LED Research Institute (GGII), sales of small-pitch LEDs in 2015 were US$678 million, China accounted for 61% of global market sales, and North American sales ranked second with approximately 19%. It is 11%.


This shows that the overseas market is undoubtedly huge.


Overseas market is infinitely good


On a global scale, it is worth noting that the international market is dominated by companies, exhibitions/exhibitions, broadcast television and retail applications, while more segmented applications in the Chinese market are concentrated in the control room environment and enterprises.


For now, small-pitch LEDs remain strong in studios, convention centers, museum artifacts, airports, businesses, and high-end commercial locations.


According to statistics, P2mm-P3.1mm products account for 58% of the total sales of small-pitch LED market, while sales of small-pitch LED products below P2 are less than 10%. Foreign packaging plants have also begun to switch to P1.6, P1.2, P1, and even P0.7 micro-pitch display technology. This will drive the market growth of LED ultra-high-definition display, bringing changes to the micro-pitch display product market below P2.0.


Relevant data show that the global video wall market sales in 2016 reached 3.4 billion US dollars, maintaining an upward trend. It is expected that next year, the rear projection video wall will account for 12% of the total sales of the video wall market, and the proportion of LCD ultra-narrow video walls will be Will be 54%, the proportion of small pitch LED will reach 34%.


The domestic market is in full swing


As far as the domestic market is concerned, in the early stage of the development of small-pitch LEDs, only a small number of enterprises invested in research and development, including listed companies such as Liard and Zhouming Technology, and with the gradual maturity of small-pitch technology, a large number of domestic displays Screen companies followed closely and entered the small-pitch market.


According to the latest data from the Higher Industrial Research Institute (GGII), in 2015, the market size of China's small-pitch LED display was 1.55 billion yuan, and the market penetration rate was 21.7%. By 2020, the market size of small-pitch LEDs is expected to reach 4.65 billion yuan. It is 2 times more than in 2015, and the penetration rate will reach 36.1%.


It is understood that Liard signed an order of 284 million yuan for small-pitch display in the first quarter of this year, an increase of 155.86% compared with the same period of last year. The gross margin of small-pitch products reached 43.3%; Alto's export contract orders for LED display products in the first quarter have reached 1940. Ten thousand dollars, most of which are high-density LED products, surpassing the total for 2015.


As the market matures, small-pitch LED display manufacturers turn their attention to their comprehensive experience, such as product volume, product structure, display performance optimization, beautiful appearance, normalization, small pitch and AR, VR, 3D Technology integration and other aspects.


Many companies have been upgrading in small-pitch products and have been breaking through. Alto Electronics has launched five new electronic products: 8K 24bit LED control system, Big Eagle LED "cloud" control platform, 1.0mm dot pitch indoor high Density LED display system, 3.0mm point spacing outdoor ultra high density LED display system, new naked eye 3D LED TV.


"The design, development and manufacture of these five new products are all completed by the company. It is a major measure for the company to expand high-end LED display products. It will further consolidate and enhance the company's technological advantages, enrich the company's product line, and further improve the company's products in high-end LEDs. Show the competitiveness of the market.” Yang Sihua, deputy general manager of Alto Electronics, revealed.


In the production of small-pitch LED display products, Chau Ming Technology pays great attention to the appearance of the products in addition to product stability and comprehensive performance. It has set up a design department to make the appearance of the small-pitch series products pleasing to the eye. The comprehensive experience of the product is more perfect.


Li Jun, chairman of Liard, said, "Since Liard has taken the lead in this field, the pixel pitch has improved from 2.5mm to 0.9mm, and 0.7mm (the world's first)."


According to the company's securities department, from the current proportion of small-pitch TV sales, the pixel pitch is 1.6mm and 1.9mm, and the market share is relatively large, while the pitch is 1.2mm, but it has not been mass-produced.


At the same time, with the expansion of the LED small-pitch market substitution effect and the strength of the LED cultural and sports media field (Lianfeng Culture and Jin Lixiang), Liard is expected to double the revenue and net profit in 15 years. The annual net profit can reach 320 million yuan.


Small pitch LEDs have been made small enough?


It is true that the small-pitch LED display technology in 2015 has been greatly developed, and the small-pitch LED display products with a minimum pitch of 0.7 mm and a dot pitch of 0.9 mm have been mass-produced. From a technical point of view, the small-pitch LED display technology has been able to fully meet the needs of market applications, and has even been ahead of market application requirements.


Under normal circumstances, people understand the small spacing is the LED display with a point spacing below P2.5, because the small pitch LED has no seams (DLP technology can currently achieve 0.2mm seam), display effect, and service life Long-term advantages.


Throughout the development of small-pitch LEDs, in 2012, P2.5's LED display entered the market and opened a small pitch era; in 2013, P2.0, P1.8, P1.5, P1.4, P1. 2 new products emerge in an endless stream, and the records are constantly refreshed; in 2014, products with smaller spacings such as P1.0 and P0.8 were also produced and introduced to the market; in 2015, the pursuit of smaller spacing has lost market significance, and now, it is even smaller. The term "technology surplus" in the field of spacing.


The designer of the small pitch must have a lot of experience to complete. On the one hand, it is a high-density screen, leakage current and wiring capacitance of the PCB, so the layout layout of the PCB, the interlayer coupling of the board and other distribution parameters must be reasonable; The driver IC and control system are combined to achieve the best results, and the general IC, system and wiring rules can only be used as a reference for design.
