[Text|High-tech LED Ganqin] With its advantages of seamless splicing, excellent display effect, continuous semiconductor technology advancement and cost reduction, the small-pitch LED display technology has officially entered various indoor application fields. The indoor large-screen display market, business meetings and education fields are all shining with a small gap.
More importantly, the birth of small spacing has also created a new gold rush point for the display industry.
Zhou Ming Technology recently released a performance forecast that the company expects net profit attributable to shareholders of listed companies in the first half of 2015 to be 52 million to 56 million yuan, an increase of 118.20%-134.98% over the same period of the previous year. The reason for the growth in performance, one of the company's small-pitch UTV series of products released, the penetration of rapid increase, created value for the company.
Liad announced in 2014 that the company's global market share of small-pitch products reached more than 70%, and this year's company's first-quarter report showed that the company's small-pitch TV realized operating income of 97.415 million yuan, an increase of 72% over the same period last year, accounting for the company. The main business income was 43.07%.
However, small-pitch displays face many technical challenges while winning opportunities.
From the perspective of the LED display industry chain, the core components from upstream to downstream mainly include chips, packaged devices, driver ICs, multi-layer PCB boards, cabinet kits, display cards (sending card/receiving card), and video control systems. , involving more related companies.
Among all components, the highest cost is packaged devices, that is, lamp beads. According to the industry, lamp beads account for 20% to 70% of the total cost.
Shao Pengrui, technical director of Jingtai Co., said that while small-pitch LEDs have many advantages, there are still many problems that need to be solved, such as how to maintain module consistency and how to ensure high reliability of display.
In order to solve the above problems, Jingtai Optoelectronics has launched a new upgraded second-generation indoor small-pitch package device "Hummingbird" series 1010, which not only solves the reliability problem of display, but also excels in heat dissipation and air tightness. Through the rigorous first-class moisture-proof grade test, it obtained the international invention patent, and the monthly capacity of the packaged device has reached 200KK.
“Our 1010 series has made great efforts in raw materials. Among them, the chip comes from internationally renowned chip companies, and the lead is made of pure gold wire.†Shao Pengrui introduced, in addition, in order to improve the super contrast of the display, the company chose imported vinyl. The imported black BT board guarantees excellent deformation resistance of the display.
Yang Lichang, chairman of Accumulation Technology, pointed out that the development of urbanization may lead to the use of indoor small-pitch display screens, but he stressed that “there are still many problems in the design of small-pitch, such as LEDs that cause poor display performance and need industry chain. The upper, middle and lower reaches are jointly solved."
Finally, for the indoor market in the indoor market, whether the small-pitch LED display can completely replace the LCD TV has become a concern in the industry. Cai San admits that “low-bright high-gray†has become a way for LED manufacturers to enter high-end display applications. The threshold that must be crossed, the small-pitch LED screen must address the reduction in brightness without loss of grayscale and image quality. At the same time, the high cost also limits the popularity of the small pitch replacement LCD market to a certain extent.
