Micro-LED is an emerging display technology that has great saturated current, low power consumption, great brightness, and high resolution, it is expected to be the next generation of display technology. However, the commercial application of Micro-LED still faces some difficulties, one of the most important is mass transfer. Mass transfer is a technology used to transfer millions of micro-LED pixels from the growing sapphire substrate to the glass substrate for display, and it needs to meet the requirements of high efficiency and precision. Many researchers from companies and universities are working on mass transfer technologies and have proposed some methods, one of which is the elastomer stamp micro-transfer-printing technology based on adhesion. In this paper, we will review the representative mass transfer technologies and study the basic principles of micro-transfer-printing technology and review different implementation methods.
