On November 6, 2024, at the Shenzhen International New Display Industry Technology Summit 2024, Mr. Xiao Junlong, Deputy General Manager of Chongqing Konka Optoelectronics Technology Co., Ltd., delivered a speech titled “Applications and Prospects of Novel Laser Technology in Micro LED”, sharing the latest advancements and future outlook of laser technology in the Micro LED field.
Differences Between Micro LED and Mini LED
Mr. Xiao began by providing a brief explanation of the key differences between Micro LED and Mini LED. While both belong to the innovative branches of LED display technology, they differ significantly in size. Micro LED chips are typically smaller than 100 microns, whereas Mini LED chips range from 100 microns to 200 microns. Due to its smaller size, Micro LED offers higher display resolution and finer display quality.
Laser Technology Fuels Micro LED Breakthroughs
Mr. Xiao then went on to explain the crucial role of laser technology in Micro LED manufacturing. Laser technology plays an important role in improving display brightness, color accuracy, and enhancing overall display performance. Compared to Mini LED, Micro LED uses RGB three-color LED chips in combination with glass packaging technology, which significantly reduces light loss. Mr. Xiao noted that the light loss in Micro LED is typically around 90%, whereas in Mini LED, it can reach up to 80%.
As resolution technology continues to advance, the applications of Micro LED have expanded beyond traditional display panels to include devices such as watches and smartphones, and it is expected to move towards even higher-resolution display products in the future.
Progress in Laser Transfer and Bonding Technologies
When discussing Micro LED manufacturing processes, Mr. Xiao highlighted the breakthroughs in laser transfer technology. Using laser cutting and transfer technology, chips can be efficiently transferred from the original substrate to the target substrate, ensuring the chip’s integrity and precise alignment. The continuous improvement of this technology has made Micro LED manufacturing more precise and efficient.
Additionally, laser technology plays a vital role in the packaging process of Micro LED. In traditional soldering processes, excessive heat can damage the chips. However, laser soldering technology precisely controls the heated areas, preventing overheating and significantly improving the quality of soldering.
Advantages of Laser Cutting Technology
Laser cutting technology also holds significant importance in Micro LED production, particularly when cutting sapphire substrates. Laser cutting achieves extreme precision, reduces material waste, and enhances production efficiency. Through laser cutting, manufacturers can meet various size and shape requirements, offering more flexibility for future applications.
Challenges and Future Prospects
Despite the ongoing challenges in the mass production of Micro LED, including issues related to production efficiency, material utilization, and cost control, these barriers are gradually being overcome as laser technology continues to evolve. Mr. Xiao emphasized that the precision and efficiency of laser technology will drive Micro LED technology to overcome mass production bottlenecks, paving the way for the industry to reach new heights.
With continuous innovation in laser technology, it is expected that Micro LED will achieve large-scale mass production in the coming years and find widespread applications in various fields, including displays and light sources. Mr. Xiao anticipates that Micro LED technology will bring higher display performance, lower production costs, and improved yield rates, contributing to a significant leap forward in the display industry.
Conclusion
In closing, Mr. Xiao stated that the application of laser technology in the Micro LED industry holds vast potential and is expected to transform traditional display manufacturing models while providing consumers with a more refined display experience. He thanked the attendees for their attention and expressed a willingness to collaborate with industry peers to drive the rapid development of Micro LED technology.
This speech provided the audience with a deep understanding of the latest developments in Micro LED technology and offered valuable insights for future technological research and industry collaboration.
