摘要
Micro-LED的发展被认为是世界上发展最快的显示技术之一,它在可见光通信应用、大型平板显示、虚拟现实及可穿戴显示、电视和照明、光遗传学和神经界面的光源等各个领域中应用广泛。尽管发展前景光明,但Micro-LED仍面临一些技术问题需要解决,以实现大规模商业化。主要技术问题包括提高长波长LED效率、提高低电流密度下的效率、全色彩方案、巨量转移、缺陷与良率管控、修复技术和成本控制。本文重点阐述了Micro-LED面临的不同挑战及其最佳解决方案。
Micro-LED is considered as a crucial and one of the fastest growing display technologies in the world as it finds its applications in variety of products from visible light communication applications to large flat panel displays,virtual reality and wearable displays,televisions and light sources for the optogenetics and neural interface.Though the prospects are bright,Micro-LEDs still face some technological problems which needs to be addressed in order to get high volume commercialization,which include improving efficiency of LEDs with longer wavelengths,improving efficiency at low current densities,full color schemes,mass transfer,defects and yield management,repair technology and cost control.This review highlights the different challenges and their optimum solutions for Micro-LEDs.
