摘要

Micro-LED技术被认为是消费电子领域下一个世代的显示技术。尽管市场上已经有很多公司推出了基于Micro-LED显示技术的样机以及应用示范，然而Micro-LED显示技术远没有达到成熟的程度。本文从Micro-LED显示技术的历史、定义及技术挑战进行了综述，重点总结了Micro-LED在工程领域的技术挑战，最后对Micro-LED技术的未来发展方向进行了探讨。Micro-LED在芯片、巨量转移、全彩化等方面仍存在技术挑战，但其所展现出的高分辨、快响应、低能耗、长寿命等突出特点，能满足超小和超大显示的需求，如虚拟/增强显示和电子广告牌，展现出巨大的应用潜力，已经在学术界和工业界引起了广泛研究。

Abstract

Micro-LED is emerging as new generation display technology due to their advantages of high efficiency

wide color gamut and long life. Although there are already many Micro LED based products and demons

the commercialization of Micro-LED technology still suffers from many technical challenges. In this short review paper

we describe the definition of Mirco-LED with a short summary of the milestones. From the perspective of the developments

we find that the integration process plays an important role in the fabricating Micro-LEDs. We then discuss the key fabrication processes of Micro LEDs with a focus on the technical challenges. In the end

a short perspective is also presented to discuss the future directions. Micro-LED display is still suffering from a number of technical challenges including mass transfer

full color technology

while the features of high resolution

fast response

low power consumption and long lifetime make them the most promising candidates for ultra-small and ultra-large displays demands

such as virtual/augmented reality and electronic billboards. These potebtial applications have motivated the exploration and investigation from both of academia and industry.
