Micro-LED在机载上的应用

Application of Micro-LED technology in airborne display

机载环境的复杂多变,对机载显示在重量、亮度、分辨率、散热等方面提出了很高的要求。Micro-LED技术存在红光LED和绿光LED内量子效率低下、器件热传递效率低下、驱动方案难以解决等问题,因此Micro-LED的技术成熟度还不能够满足机载显示对主显示及微型显示器件的高要求。但是,Micro-LED具有高亮度、高分辨率、高像素密度等LCD和OLED不可比拟的优势,有望用于机载环境下的平视显示仪、主显示等应用场景。本文综述了Micro-LED的研究进展,提出了Micro-LED亟待解决的技术问题,探讨了相关技术问题可能的解决方向以及Micro-LED在机载上的应用前景。总之,Micro-LED的轻质、高亮度、高分辨率等特性足以满足机载显示在重量、亮度、分辨率等方面的高要求。理论上,由于Micro-LED具有优异的显示特性,Micro-LED显示技术将会成为机载显示极具优势的新型显示技术。

In order to cope with the complexity and change of the airborne environment,airborne display is required to have high performances in weight,luminance,resolution,and heat dissipation.Micro-LED technology has problems such as low internal quantum efficiency of red LED and green LED,low heat transfer efficiency of the device,and difficulty in solving the driving scheme.Therefore,the technological maturity of Micro-LED is not yet able to meet the needs of airborne display for main displays and micro displays.However,Micro-LED has the incomparable advantages over LCD and OLED,such as high luminance,high resolution,and high pixel density,and is expected to be used in application scenarios such as head-up displays and main displays in airborne environments.This article reviews the research progress of Micro-LED,puts forward the technical problems of Micro-LED urgently to be solved,and discusses the possible solutions to related technical problems and the application prospects of Micro-LED on airborne.In short,Micro-LED's light weight,high luminance,high resolution and other characteristics are sufficient to meet the high requirements of airborne displays in terms of weight,luminance,and resolution.Theoretically,due to the excellent display characteristics of Micro-LED,Micro-LED display technology will become a new display technology with great advantages for airborne display.
