On February 6, Lehman shares said in an institutional survey that the company's COB display has been commissioned in January and will be mass-produced in March, with expansion in each quarter.
COB (Chip On Board) is an integrated packaging technology. COB technology has always been favored by the industry, and is even considered to be the only way for LED display technology to lead to Micro LED.
At present, the COB small-pitch LED display application market is very extensive, mainly including broadcasting and television broadcasting, command and control center, video monitoring main screen, conference display and cinema line.
Li Mantie, chairman of Lehman Co., said, “We are more optimistic about the market capacity of COB displays, because the market capacity of LED small-pitch displays is growing. In addition, Micro LEDs are still too far from our industry. Far, so COB is still the best choice."
As we all know, the miniaturization of lamp beads is bound to be a long-term process, but it also brings many new challenges to the industry. For example, smaller lamp beads mean more intensive integration, which undoubtedly poses a greater challenge for existing SMD processes.
“To some extent, this is also the reason for the increased focus of packaging technologies such as COB. COB display technology is driven by differentiated market strategies and higher profits, which is bound to promote its rapid development and must be highlighted in homogenization competition. The inevitable choice for the market to seek differentiated development in the Red Sea." Li Mantie said.
Of course, at this stage, many companies are also supporting the Micro LED.
Recently, Sanan Optoelectronics announced that its wholly-owned subsidiary Xiamen Sanan Optoelectronics Co., Ltd. (hereinafter referred to as “Xiamen Sananâ€) signed a “prepayment agreement†with Samsung Electronics. The contract stipulated that in order to establish a long-term business relationship, Samsung Electronics will pay a pre-payment of 16.83 million US dollars in Xiamen Sanan in exchange for a certain number of LED chips for display products ("display") in Xiamen Sanan production line. If Samsung Electronics' monthly order volume may exceed the agreement The maximum number of parties will discuss the conditions for expansion in advance.
Xiamen Sanan and Samsung Electronics will continue to discuss the strategic cooperation of Micro LED. When Xiamen Sanan reaches mass production capacity, Samsung Electronics will consider Xiamen Sanan as the primary supplier and negotiate a supply agreement acceptable to both parties. Through this strategic cooperation, Samsung Electronics expects to ensure a strategic and stable supply side, and Xiamen Sanan expects to lead the Micro LED market.
It is worth mentioning that at CES 2018, Samsung successfully launched a 146-inch giant TV The Wall, which is the first product developed by Samsung using MicroLED technology, which not only has super high quality and Contrast, also with a modular design, the screen is seamlessly spliced ​​from multiple smaller panels, so the screen size has the possibility to zoom in or out as needed.
In addition to Samsung's products developed using Micro LED technology, Sony, Apple, Foxconn, Google, BOE, Huaxing Optoelectronics, Innolux, AUO and other well-known companies have been deployed in 2017, and have launched related product.
It is undeniable that the display of the Micro LED field has formed an industry trend. However, under this craze, there are inevitably many facts that are difficult to cover up. For example, Micro LED currently has two crucial problems, one is high cost, low yield, and difficult to mass production. The other is that Micro LED technology is difficult to be flexible. If these problems cannot be solved, then Micro LED technology application Will be severely limited.
Despite this, the prospects for the Micro LED market are still optimistic. In the 2017 semi-annual report, Sanan Optoelectronics revealed that it is foreseeable that once the Micro-LED industrial chain link is opened, the market capacity will increase exponentially.
Therefore, not only is Sanan Optoelectronics active in the Bureau, but also LED chip manufacturers such as OSRAM, Cree, Nichia, Jingdian, Longda Electronics, Huacan Optoelectronics, and Dry Photoelectric are actively investing in the layout.
