BOE/Leyard/Unilumin/Ledman/Absen disclose MicroLED progress

Recently, BOE, Leyard, Unilumin Technology, Ledman Optoelectronics, Absen and other companies have successively revealed their progress in Micro LED on investor platforms.

BOE: It has been conducting research and layout on Micro LED technology for many years

BOE revealed that the company has been researching and laying out Micro LED technology for many years and continues to promote the industrial development of Micro LED technology. The company controls upstream LED chip company Huacan Optoelectronics through industry resource integration, is deeply involved in the planning and development of Micro LED chips, and continues to improve chip efficiency.

The company has cooperated with internationally renowned equipment and materials companies to develop technologies related to mass transfer. It has now completed the planning and construction of the 2.5th generation mass transfer pilot line and achieved internal development of mass transfer technology;

In addition, the company has been deeply involved in the semiconductor display field for more than 30 years and has accumulated industry-leading high mobility and low impedance backplane technology, and has achieved mass production of multiple LTPS/LTPO backplane production lines. In recent years, the company has continued to actively deploy in the industrial chain to promote better and sustainable development of the industrial chain.

Leyard: Micro LED has achieved a breakthrough in orders from 0 to 1 billion in the field of large-screen commercial displays

Leyard said that since the company launched Micro LED in 2020 In the mass production of LED, the production technology has been continuously improved, the production capacity has been doubled, and the cost has been significantly reduced in the past four years. Currently, orders in the field of large-screen commercial displays have achieved a breakthrough from 0 to 1 billion, and applications have further extended from high-end to mid-to-high-end. Next, we will increase the use of Micro in more application scenarios, and realize the expansion from B-side to C-side.

The company's high-end MiP products adopt a substrate-less Micro LED design, with a large viewing angle, no color shift, and stable color temperature, ensuring color accuracy and display effect stability at different viewing angles. It is especially suitable for film and television shooting and production fields such as XR and VP. The color uniformity and consistency between modules are effectively improved. Compared with traditional LED displays, power consumption is reduced by about 25%. Due to the use of smaller-sized lamp beads, it is more suitable for special display fields such as transparent display modules and movie sound-transparent screens.

Unilumin Technology: It has built a complete industrial chain layout in the field of Micro LED

Through independent research and development, strategic investment and resource integration, the company has taken a leading position in the field of Micro LED and built a complete industrial chain layout from independent design of Micro lamp beads, independent design of Micro IC, semiconductor packaging to intelligent manufacturing.

In terms of new MiP packaging technology, the company took the lead in breaking through the problem of mass transfer technology and realizing Micro LED 30 micron * 50 micron size substrate-less technology 0202 packaging, and simultaneously realized the mass production of MiP P0.4 pitch display products. In the future, with the cost reduction and technological breakthroughs of Mini LED and Micro LED products, it will be possible for LED direct display to enter the consumer market.

Ledman Optoelectronics: Small-batch trial production of PM-driven glass-based Micro LED display panels has been achieved

Ledman Optoelectronics stated that the PM-driven structure + glass substrate innovative solution jointly developed and launched by the company and its upstream partners has broken through key core technical problems such as massive through-hole technology, thick copper technology, and through-hole copper filling technology, and solved the shortcomings of glass substrates that are easily broken and difficult to subsequently repair. The Micro LED display based on PM driven glass is extremely thin and light, has extremely high flatness, very low power consumption, fast heat dissipation, and ultra-high color reproduction. It is a very cost-effective product that takes into account both display effect and cost.

The company has achieved small-batch trial production of PM-driven glass-based Micro LED display panels, and is currently continuing to explore and upgrade glass-based technology through the construction of pilot bases. In the future, it will be expanded to be used in a series of ultra-large-size Micro LED display products and solutions such as Ledman smart conference interactive display systems, Ledman smart education interactive display systems, and Ledman ultra-high-definition home giant curtain walls, to fully meet the multi-scenario low-cost, low-energy consumption needs of future dedicated displays, commercial displays, home displays and other fields.

Absen: Continue to increase investment in research and development of core technologies such as Micro LED

Absen said that the company has always attached great importance to R&D construction and investment. From 2021 to the first half of 2024, the company has invested a total of approximately 484 million yuan in R&D expenses, and continues to increase R&D investment in core technologies such as Micro LED, virtual shooting, LED all-in-one machines, outdoor small spacing, LED fire retardant, and home theater. This strongly supports the overall improvement of the market competitiveness of the company's products, as well as its continued leadership in cutting-edge technologies such as XR virtual production, home theater, outdoor naked-eye 3D display, Micro LED, and COB.
