The Current Bottleneck and Technical Progress of Micro LED
Micro LED technology, as a cutting-edge research field in next-generation display technology, has advantages such as high brightness, high contrast, and high energy efficiency. The development process of Micro LED technology has been reviewed, focusing on its technical difficulties and current progress. The technical difficulties include epitaxial structure design, size effects in chip preparation, full color issues, Micro LED system integration, and reliability research. The current progress covers sidewall effect suppression, full color scheme, massive transfer technology, nitride red light technology, color conversion, vertical stacking, CMOS and TFT driving, 3D integration, transparent display, and nano LED. Finally, an outlook on the future development direction of Micro LED technology has been proposed, including addressing technical challenges, promoting industrialization, and achieving wider applications.
