Micro-LED, as an inorganic self-emitting display technology, has garnered significant attention and is regarded as one of the most promising display technologies following TFT-LCD and AMOLED. With the ongoing maturation of the technology, Micro-LED’s applications are constantly expanding and integrating. Tianma Microelectronics, as one of the leading companies in the global new display industry, has always been at the forefront of technological innovation, committed to the advancement of new display technologies. In the future, the association will collaborate with government agencies and industry enterprises to promote industrial integration, build a cooperative innovation system, accelerate market cultivation, and create a healthy industry ecosystem to achieve a dual circulation in the global Micro-LED industry.
Mr. Peng Xuhui, Chairman of Tianma Microelectronics, expressed his sincere gratitude to the leaders, alliance members, and industry chain partners present at the conference. He noted that the Micro-LED Ecological Alliance has flourished with collective support. Currently, the alliance has over forty member companies, all collaborating with industry chain partners in key areas such as end-user applications, equipment, and materials. He stated that Micro-LED is a field full of endless possibilities and challenges, requiring joint efforts to explore new frontiers of technology. China’s display industry has bright prospects in the future, with Micro-LED playing a crucial role in shaping its success.
Keynote Presentations
Ms. Geng Yi, from the China Academy of Information and Communications Technology, delivered a report titled “Exploring the Development and Application Trends of Micro-LED Technology.” The report focused on the Micro-LED industry and technology development, analyzing the current application trends and providing valuable insights and suggestions. She stated that Micro-LED is a critical direction for the development of the new display industry. Thanks to the joint efforts from industry, academia, and research institutions, the Micro-LED industry has made rapid progress in recent years. However, she noted that Micro-LED technology still faces challenges related to pixel miniaturization, drive precision, and innovations in epitaxial growth consistency, massive transfer efficiency, full-color coordination, and testing accuracy. With high costs, fragmented industry links, and inconsistent standards, she urged for enhanced top-level design, improved investment mechanisms, and greater cooperation to promote the construction of the industry ecosystem.
Mr. Huang Fei, General Manager of Hisense Visual LED Product Line, delivered a report titled “Opportunities and Prospects for Micro-LED End-Product Development.” The report discussed the market opportunities arising from large-screen display trends, as well as new scene innovations for Micro-LED applications. He also highlighted key challenges related to core components and technologies and proposed solutions involving computational power, algorithms, and data.
Dr. Kai Schmidt, Vice President of Coherent, presented a report titled “Laser Technology Empowering Micro-LED Display Manufacturing.” He discussed the role of laser technology in the Micro-LED manufacturing process, exploring next-generation laser technologies that offer superior characteristics and compatibility. He also presented test results for Micro-LED RGB chip transfers, introducing various laser options, optical systems, and integrated equipment.
Mr. Qin Liang, Executive Vice General Manager of Shengxian Microelectronics, gave a report on “TFT-based Micro-LED Driver Chip Technology.” He presented solutions for Micro-LED’s low power consumption, fast response time, high color gamut, and unique challenges presented by different TFT backplane structures, particularly in terms of simpler control and driving circuits for TCON, addressing common issues like Gamma and Mura.
Mr. Xi Keri, Secretary-General of the Micro-LED Ecological Alliance and Deputy Director of Tianma Micro-LED Research Institute, delivered a report titled “Key Developments and Prospects for Tianma Micro-LED.” He highlighted the challenges that Micro-LED technology faces during industrialization, including yield rates, production capacity, supply chain, and application push. He provided Tianma’s solutions to these challenges and outlined the company’s achievements since 2017, including launching the highest transmittance automotive transparent display, the highest pixel density glass-based Micro-LED wearable display, the narrowest seam seamless display technology, and the smallest bending radius flexible Micro-LED technology. Tianma’s new G3.5 automated mass transfer line was also showcased in June 2024, marking a significant breakthrough.
Industry Chain Summit Discussion
In the final summit discussion, representatives from associations, universities, and the Micro-LED industry chain gathered to discuss the progress of Micro-LED industrialization.
Mr. Huang Fei, General Manager of Hisense, expressed his commitment to building a collaborative ecosystem with Tianma and other alliance members, seeking solutions to the standardization issues within the industry.
Mr. Huang Shaohua, Vice General Manager of San’an Semiconductor, emphasized the importance of an open and collaborative mindset for Micro-LED technology‘s industrialization.
Mr. Yuan Gongshu, Vice President of Delong Laser, reiterated the need for advancements in laser technology to support Micro-LED’s progress.
Qingdao Xinxin Microelectronics Co., Ltd. Product Line Vice General Manager Gong Jingwen believes that the current differences in technology paths among industry players have led to variations in massive transfer technology and algorithms. As a result, achieving the development of a universal TCON still requires some time for exploration.
Finally, Professor Guo Tailiang, Vice Director of the National New Display Technology Innovation Center, stressed the importance of platform validation for Micro-LED technology and collaboration between leading enterprises.
Mr. Qin Feng, Chairman of the Micro-LED Ecological Alliance and Director of the Micro-LED Research Institute, stated that the efficiency of massive transfer and cost control remain bottlenecks.
