Presently, liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays are two dominant flat panel display technologies. Recently, inorganic mini-LEDs (mLEDs) and micro-LEDs (μLEDs) have emerged by significantly enhancing the dynamic range of LCDs or as sunlight readable emissive displays. “mLED, OLED, or μLED: who wins?” is a heated debatable question. In this review, we conduct a comprehensive analysis on the material properties, device structures, and performance of mLED/μLED/OLED emissive displays and mLED backlit LCDs. We evaluate the power consumption and ambient contrast ratio of each display in depth and systematically compare the motion picture response time, dynamic range, and adaptability to flexible/transparent displays. The pros and cons of mLED, OLED, and μLED displays are analysed, and their future perspectives are discussed.

目前，液晶显示器（LCD）和有机发光二极管（OLED）显示器是两种主要的平板显示技术。最近，无机迷你 LED (mLED) 和微型 LED (μLED) 显着增强了 LCD 的动态范围或作为阳光下可读的发射显示器而出现。“mLED、OLED 或 μLED：谁胜出？” 是一个备受争议的问题。在这篇综述中，我们对 mLED/μLED/OLED 发射显示器和 mLED 背光 LCD 的材料特性、器件结构和性能进行了全面分析。我们深入评估了每款显示器的功耗和环境对比度，并系统地比较了运动图像响应时间、动态范围以及对柔性/透明显示器的适应性。分析了 mLED、OLED 和 μLED 显示器的优缺点，并讨论了它们的未来前景。
