Micro-LED is superior to LCD and OLED in terms of power consumption, light efficiency, contrast, response time, reliability, color gamut, lifetime, resolution and viewing angle, it is regarded as the most promising display technology in next generation. However, there are still many technical bottlenecks that hinder the development of Micro-LED display. One of the most important technical issues is mass transfer. Mass transfer is a technology aim to transferring millions or even tens of millions of Micro-LED pixels which grown on sapphire substrates to the glass substrates required for display devices quickly and correctly and providing good electrical and mechanical connections between the Micro-LED pixels and the drive circuits. There have been many companies that have been working to solve this problem and have come up with solutions from different technical aspects. In this paper, we will review several different technologies, classify them from the technical type, evaluate the maturity and achievability of the technology, and analyze the application fields of different technologies.
