Mini LED hot,COB display to "cool" it?

The World Cup is in full swing, with the enthusiastic eyes and passion of fans around the world destined to blew up this summer. However, as the game progresses, all kinds of unpopular explosions make fans around the world feel the breath. Depression

On June 8th, under the concern of many media, National Star Optoelectronics Guangzhou Shangri-La Hotel has released its latest mini LED display products. At the same time, at the US infocomm trade show on the other side of the ocean, National Star Optoelectronics has jointly exhibited the latest mini LED display products together with Junghwa Optoelectronics. Once the product was launched, it triggered a strong response at the show and became an attraction for the entire show. Eye focus.

For a time, media reports from the industry and companies are all mini LEDs. It can be said to be overwhelming. Other media and companies have also followed suit and have actually set off a mini fever.

The industry believes that mini-LEDs with a size of about 100 micrometers are feasible without overcoming mass transfer of technical thresholds. They can be used for applications such as large-size display screens, TVs, and mobile phone backlights. As early as the second half of 2017 has entered the product design and certification stage, and led the LED backlight restart.

In fact, mini LED appeared in the public view is not the first time, at the US infocomm show, Alto Electronics also released the latest "mini LED commercial display system", also received good response. In fact, in the industry, it has publicly stated that mini-LEDs are led by Ruifeng Optoelectronics, crystal Taiwan, Crystal Thai Star, China and other glorious LED companies, with the help of these companies, how can the mini LED's momentum is small?

But some people also look at the situation and think of the COB, which was very hot before.

Domestic LED packaging companies saw the traditional SMD packaging technology in the field of LED small pitches gradually incompetent, it seems difficult to make breakthroughs, they are hoping to emerge new packaging technology can continue to promote the development of LED small pitch. The emergence of COB packaging technology has also given many companies eager eyes and attention. The COB technology has not lost its mission and has allowed the development of small gaps to make significant progress. This has also kept the heat of the COB high for the past few years. Especially in the second half of last year, Lehman introduced a third-generation COB display product. Various discussions about COB are endless. Compared with the current mini LED, It is worse than nothing.

As a new type of packaging technology, COB directly replaces the two-step process of “mounting the surface of the lamp to the surface of the lamp bead”. This brings more space and more possibilities to the LED display industry. At the same time, it has also attracted a large number of companies as strength advocates. There are several representative domestic enterprises including Lehman, Xida and Absen. This also indicates that the future potential of COB remains to be tapped. I believe that in the near future, it will bring us more surprises and inject more vitality into the LED industry.

That mini LED hot, COB really want to "cool" it?

First of all, we must first look at the next, the definition of the two is actually not the same, COB is a new type of packaging technology, the current industry mainly serves small LED spacing, and mini LED is actually in accordance with the spacing between the display elements Defining, generally speaking, the industry calls the LED with 50 to 100 micrometers as the mini LED, so from the definition, the two do not conflict.

Second, from the layout point of view, the advancement of a technology is inseparable from the technological investment of large enterprises and the overall layout of the project. Like the dispute between LCD and plasma mainstream display ten years ago, many companies have taken great efforts on LCDs. Only Changhong is loyal to the plasma giant. It also shows the situation of Changhong's isolation. The display performance of plasma is far better than that of LCD. However, the plasma is 100 kilograms worse in market acceptance. Today, it is already thin. The situation. The strength of both COB and mini LED advocates is undeniable, and the number is not limited. No matter whether domestic listed companies or international giants have worked hard on them, there is no such thing as plasma. problem.

From the perspective of technical feasibility, both have their own weaknesses in display performance. The disadvantages of COB are high cost, black plastic fixation, easy to cause reflection, maintenance, ink yellowing, and wavelength uniformity need to be considered. The problem. The Mini LED, other than the other, said that the current form is still a single discrete device is criticized by people, and to its maturity stage, must be a non-single discrete device, or that is a cell board module The form of the market appears in the market. Therefore, there are still many problems to be solved between the two, and the technology needs to be further improved.

The most deadly thing is that the prices of the two have not reached the point where people are close to themselves, and the LED display industry itself has decided that even the best technology should be lowered on high costs. The production costs of both have yet to be improved with the technology. The gradual decline, and the cost of the decline in progress depends on the major companies of technology research and development efforts.

In summary, the mini LED's big heat makes people feel that COB should be "cool". It is really awkward. Both of them are not in the mainstream of the display market. Why is there a high heat to force another to die? In fact, because of the industry volume problem, the industry is so big. There are so many kinds of popular technologies. Companies that promote a display technology product tend to ascend. Other companies that promote the same technology have responded to it and become a comrade in their own battle. Flags shouting, and thus have increased propaganda, so this problem is not surprising.

How will the future of both go?

May also give us some inspiration at the infocomm exhibition in the United States. Xida Electronics unveiled a series of Mini LED COB products at the infocomm exhibition in the United States. The appearance of the CeDC electronic Mini COB has attracted the attention of many international major project companies at the InfoComm exhibition. The scene caused a wave, attracting a large number of professional customers to look around and consulting, and even some of them were attracted to see the grace of the Mini COB, and saw that the Mini COB of Xida Electronics was excellently displayed, with extremely high contrast and high reliability. As a result, many customers directly placed orders to purchase samples for marketing, and the overseas markets responded strongly.

Coincidentally, on June 6, the domestic industry giant Liad also said on the interactive platform: The company is currently developing a COB type mini LED small pitch product, using mini LED crystals as display pixels, flip-chip COB technology processing, now The stage is under trial production in small batches.

What does this mean? We also mentioned that the definitions of the two are completely different. The COB is a new packaging technology. The mini LED refers to the spacing between display elements. The two do not conflict. Now it seems that the two are not only non-conflicting, but also can be a good combination, I believe it is also strong and powerful, extraordinary, absolutely not one plus one is equal to two as simple.

The two can not be well integrated and complementary. This involves many technical problems. We cannot predict whether the two are combined and developed well, or whether they can be developed independently, but no matter what the development of the two will bring to the industry. The next generation of display technology disputes will not cease, and the future of display technology must be flourishing, and there will be varying degrees of competition in various segments.

Regardless of how the next generation of display technology will be innovated, our LED display industry professionals must be calm and conscientiously engage in technology and do business in a down-to-earth manner. Only in this way can we continuously innovate and lead in a variety of display technologies in an orderly manner. Show trends.
