Why does the Micro LED replace the LCD?

——Interview with Liang Zechun, Marketing Manager, Opto Semiconductor Semiconductor Industrial Applications Division

Article Source: "LED Screen Display World" August issue - high-end interview

LED screen display world:

The micro LED has a natural advantage in the ultra-small-pitch LED display. Do we have to continue to die with the advantage of spacing? Micro LED really grows up, and LED competes with the large-size market. What kind of problems still need to be solved? After a long time, will we meet this opponent?

Mr. Liang Zechun:

This statement is somewhat inaccurate, Micro LED or CoB is based on LED chip technology, but the package is not the same form, just like LED lamp beads have different packages, just the specific application scenarios Focus and difference, the two do not contradict or conflict. Manufacturers of display screens can comprehensively utilize the length of the two, and select different packaged products under different application scenarios and different technical requirements.

LED screen display world:

Recently, many companies have announced their entry into Micro LED, which is considered to be the technology of the next era. Your company is the leader in the packaging industry. How do you think about this kind of viewpoint? What is the concept of Micro LED?

Mr. Liang Zechun:

I think this is one of the important directions for the development of LED display applications. Through the development of Micro LED technology, more practitioners can be guided to pay attention to and input the reliability of LED display, the display effect is improved, and the realization of display technology energy saving is urgent. Sexuality, which can fully exploit the advantages of LED display technology, and thus provide a possibility to replace LCD or other display technologies. Osram is not only an expert in the packaging industry. We have thousands of patented technologies in the construction of LEDs for epitaxy, chips, optical conversion, packaging, etc. It is the market leader in LED related technology. Osram will not miss this opportunity to enter the ultra-small-pitch display application market.

LED screen display world:

In the LED industry, packaging has always led the development direction of LED applications. It is precisely because of the miniaturization of LED devices that LEDs have small spacing. But now this model is gradually turning into an application-driven R&D approach. How does your company view this shift and will it adjust to this trend?

Mr. Liang Zechun:

There is no problem of transformation. The development of our LEDs has always corresponded to certain market and application requirements, or potential application requirements. Take our outdoor large-screen black light products as an example. When developing this product, We foresee the market demand for high-contrast outdoor large screens. At this time, the market is not yet mature, or a large number of screen factories do not understand this. We have introduced such products to the market and guided these demands when the market matures. After that, more and more manufacturers recognize this technology and recognize that it brings value to display applications. It will be considered that packaging technology has guided market references. In fact, our product development design and new product launch have never been separated from application needs. Or potential applications need.

LED screen display world:

Nowadays, the application market is getting wider and wider, and there are more and more sub-divisions. Each field has its own focus. What impact does this have on the packaging field? Does this lead to subdivision in the packaging field as well?

Mr. Liang Zechun:

The application market is getting wider and wider, the application scenarios are more and more diverse, and the application requirements are more and more, which requires a wide variety of package products. As an important advantage of LED display, its flexible design and depending on the scene. product. In the field of packaging, this will play a more and more important role. The packaging field has been subdivided, starting from automotive, lighting, display, backlight, etc., to indoor and outdoor display applications, high contrast, high angle and small angle. Etc. has begun to subdivide the form of the package in different application scenarios.

LED screen display world:

Now China is the world's largest LED display manufacturing site, and the display screen accounts for more than 80% of the world. It can be said that it is a big consumer of LED devices. What kind of layout will your company make as a packaging giant? In what way will the influence of the Chinese market be maintained?

Mr. Liang Zechun:

After more than 20 years of development, the Chinese display market has become more and more mature, with more and more innovative capabilities, and has achieved great results in the global market. Of course, it also faces a series of problems, such as quality reliability, light pollution, high energy consumption and other issues that need attention. Since 1999, OSRAM began to commercialize the world's first RGB signature three-in-one product, and has continued to innovate in the display field, providing a series of new products and technologies. Osram Opto Semiconductors Asia Pacific Support Center is located in Wuxi, China. We not only provide high quality LED lamp beads, but we also provide system level optical, thermal and process support for Chinese customers based on research on display applications. From perfect product line diagrams to ingenious chip and packaging technologies, and system-level technical support, OSRAM will help the healthy development and continuous innovation of the Chinese display industry.
