November 6, 2024, at the Shenzhen International New Display Industry Technology Summit 2024, Changhui Zhuang, R&D Director at Guangdong HSET, delivered a speech titled “Progress in Micro LED Display Development and Sharing of Laser Mass Transfer Technology,” shared the latest advancements in Micro LED display technology and discussed the crucial role of laser mass transfer technology in the mass production of Micro LED displays.
The Rise of Micro LED Technology
Micro LED technology is gradually emerging as one of the key directions in the display industry. During his presentation, Zhuang highlighted that Micro LED offers significant advantages in terms of high brightness, high contrast, low power consumption, and wide color gamut, making it a highly promising solution for high-end display applications. While the technology faces challenges in terms of precision and efficiency in the manufacturing process, continuous technological innovation is driving it toward larger-scale adoption.
Zhuang emphasized that Guangdong HSET has made significant breakthroughs in Micro LED technology, particularly in the development and production of ultra-high resolution displays. He also explained how the application of laser mass transfer technology has provided an innovative solution for addressing the alignment and transfer challenges between Micro LED chips and their substrates.
Laser Mass Transfer Technology: A Key Breakthrough
One of the core challenges in Micro LED production is the precise positioning and efficient transfer of the tiny LED chips. Zhuang provided a detailed explanation of the working principle behind laser mass transfer technology: by precisely controlling the laser’s power and energy, the technology enables the rapid and efficient transfer of Micro LED chips without causing any damage to the chips. This breakthrough has greatly enhanced both the production efficiency and yield rate of Micro LED displays.
He further pointed out that laser mass transfer technology not only addresses the challenges of alignment and transfer in Micro LED manufacturing but also significantly reduces production costs, accelerating the commercialization process of Micro LED display technology.
Technological Prospects and Industry Outlook
As laser mass transfer technology matures, the application scope of Micro LED is expected to expand rapidly. From smartphones and televisions to wearable devices, Micro LED is quickly gaining traction across various high-end display applications. Zhuang believes that in the coming years, Micro LED will become one of the dominant display technologies, particularly in the premium market, and will gradually replace traditional OLED and LCD technologies.
He also emphasized that Guangdong HSET will continue to invest in research and development, with a focus on driving the technological innovation that will enable the display industry to transition to the next level. Especially in the area of Micro LED technology, the company is committed to advancing large-scale production and market applications, which are expected to have a transformative impact on the industry.
Conclusion
Director Zhuang’s speech provided an in-depth look at the current state and future challenges of Micro LED display technology, particularly the application of laser technology and mass transfer techniques in Micro LED production. With continuous advancements in these technologies, the development potential for Micro LED displays will only expand. Despite some challenges, Micro LED holds the promise of a major role in the display industry due to its unparalleled performance and the potential for future cost reductions.
