摘要

Mini-LED是Micro-LED的先导技术，在液晶显示应用中被定义为“高阶直下式再升级”产品。最近各大终端消费电子品牌相继推出了基于Mini-LED背光的新产品，成为TV行业新的技术发展趋势。最近，Mini-LED背光技术迅速发展，与之相关的芯片、封装、面板以及整机等行业内的重要供应商相继入局，形成了推动Mini-LED背光技术发展的重要力量。本文从TV技术的角度出发，介绍了近期Mini-LED背光技术的研发进展，阐述了Mini-LED背光技术对推动消费电子领域产品技术革新的重要意义，在此基础上从技术和应用的角度探讨了Mini-LED背光技术当前面临的主要挑战，并对未来发展趋势进行了展望。

Abstract

As a primary level of Micro-LED

Mini-LED backlights are emerging as an advanced TV technology of "high-end direct upgrade". Currently

many consumer electronics companies launched Mini-LED backlight embedded products

including high-end displays

notebooks

tablet computers

car displays

and so on. Motivated by the promising future

there are many suppliers working on the commercialization of Mini-LED technology related components including chips

packages

panels

and complete machines. This review describes the key technology of Mini-LED backlight technology and the status of current commercialization. This paper also discusses the prospect and challenges of TV technology in future developments.
