Introduction:

On April 14, the 2021 expert said that the micro-pitch LED display innovation application conference was held in Shenzhen. Director Guo Heng, Director of National Star Optoelectronics Micro&Mini LED Research Center and Deputy Director of R&D Department of RGB Super Business Unit, shared a keynote speech on "Fine Pitch Era, IMD Packaged Devices Accelerating Commercialization of P0.X Market Scale" from P0.X Mini The LED display market trend, the evolution of P0.X Mini LED display packaging technology, and the industrialization layout of IMD packaging are analyzed and explained.

The rapid development of the micro-pitch display market

At the meeting, Director Guo Heng first reviewed the P0.X Mini LED display market trend. He couldn't help sighing that in just one year, the micro-pitch shows that the market is developing rapidly, and many manufacturers are speeding up the volume.

He believes that today's Mini LED display market trends mainly have the following characteristics: the dot pitch is getting smaller and smaller, the pixel density is getting higher and higher, and the viewing scene is getting closer and closer.

Regarding the scale of the Mini LED interactive application market, Director Guo Heng said that several statistical data will be used to present the explanation:

● Mini LED flat panel market scale is over 1 trillion yuan;

● The focus of Mini LED delivery panel is 100-200 inch large screen display, and the market size is expected to exceed 100 billion;

● In 3-5 years, as the cost of Mini LED flat panel displays drops to less than 50,000-100,000/unit, the penetration rate will further increase, and it is expected to move towards a trillion market.

With the continuous improvement of LED display technology, the miniaturization of LED display dot pitch has become a trend. Entering 2021, the new products of LED display manufacturers have achieved breakthroughs in some high-end application fields, and display products with P0.9 and even smaller dot pitches have begun to appear one after another. However, the ability to mass produce does not mean the ability to commercialize on a large scale.

At present, the display effect and overall cost are still the primary tasks in the new application market for micro-pitch displays.

The key to each technical route is to quickly reduce costs and achieve industrialization

Currently on the market, the main packaging solutions for Mini LED displays include SMD, COB, and IMD. The advantages and disadvantages of these solutions are as follows:

Although various packaging technologies are blooming at this stage, each has its own strengths, but the key lies in how to quickly reduce costs and achieve industrialization.

IMD is the fastest mass production solution for micro-pitch LED displays

According to Director Guo Heng, IMD packaging equipment is more than 80% compatible, and the industrial supply chain (chips, substrates, wires) and equipment are mature. The screen factory can quickly cut in. With the synergy of packaging companies, the cost can be greatly reduced. The fastest solution for P0.9-P0.4 mass production;

NationStar Optoelectronics is a representative company in the LED display packaging industry that mainly promotes IMD packaging technology and realizes P0.X display. In 2018, it took the lead in mass production and launched IMD-M09T. After three years of development, the fine pitch products of IMD packaging have covered P1.5~ P0.4. When the mainstream of the industry dot pitch is still at P1.2, the National Star Optoelectronics RGB Super Division quickly launched the P0.9 dual version (standard version and flagship version) in November 2020.

As the next explosive product following P1.2, P0.9 is highly anticipated by the industry.

According to reports, among them, the standard version, the target price is P1.2, has a high level of anti-collision ability, 4 times the placement efficiency, superior color consistency, large-scale mass production and other advantages, which directly accelerate the Mini/Micro LED Show the scale of industrialization. Mini 0.9 flagship version will usher in a new round of comprehensive upgrades. Compared with the first generation Mini 0.9, its contrast, color gamut (covering DCI-P3 color gamut), brightness (full screen brightness increased by more than 50%), and reliability And other aspects have been greatly improved, and the comparison is as follows.

At the same time, the Shanghai AWE Exhibition in March this year launched a 136-inch 4K large screen, and also adopted the IMD solution to show the industry that the next-generation dot pitch of Mini LED mass production has been reduced to P0.7, which has aroused the attention of the entire industry. (Note: National Star Optoelectronics has released the mass-produced IMD-M05 at the 2020 ISE exhibition).

Finally, Director Guo Heng also disclosed at the meeting that in response to the needs of end customers, the RGB Super Business Unit of NationStar Optoelectronics will achieve further expansion in the near future, and the Mini LED production capacity will be doubled.
