Connoisseurs say research
Wang Jinghe**Associate Editor-in-Chief
Experts say that Wang Jinghe, deputy editor-in-chief of research, brought a special speech on "Mini LED Industry Dynamics and Development Trends" at the meeting.
In terms of the Mini LED backlight market this year, the TV sector increased by nearly 50% year-on-year, and is expected to become the main sector in the Mini LED backlight. In the short term, the main growth of Mini LED backlights is coming from TV and MNTIn the medium term, it will be gradually implemented in outdoor displays, drones and other scenariosIn the long run, Mini LED backlights will be used in automotive displays and other scenarios that require high reliability.
Afternoon session:
Opportunities and challenges for new LED displays
Unilumin Group. Zhang Jingang R&D Director
Zhang Jingang, R&D Director of Unilumin Group, delivered a keynote speech on "Opportunities and Challenges in the Era of New LED Display".
Zhang Jingang believes that the industry is about to enter a new era of mini micro LED. In the Mini Micro era, the industrial chain layout and competition pattern will be reconstructed, the product form and industrial ecology will change, and the "ChipCob + dynamic pixel technology" will achieve 2K 4K 8K display upgrade at low cost, and at the same time, the whole industry chain will face the opportunities and challenges brought by new underlying technologies and industrial restructuring.
