Recently, “liquid crystal display (LCD), organic light‐emitting diode (OLED), or micro‐light‐emitting diode (LED): who wins?” is a heated debatable question. In this review article, we provide a comprehensive overview of these three promising display technologies through nine display performance indicators, including ambient contrast ratio, motion picture response time, viewing angle and angular color shift, color gamut, resolution density, power consumption, cost, lifetime, and thin profile and panel flexibility. The advantages and disadvantages of each technology are analyzed, and their future perspectives are discussed. In this review article, we give a comprehensive overview of three promising display technologies (liquid crystal displays [LCDs] with mini‐light‐emitting diode (LED) backlight, organic LED [OLED] displays, and micro‐LED [μLED] displays) through nine display performance metrics, including ambient contrast ratio, motion picture response time, viewing angle and angular color shift, color gamut, power consumption, resolution density, cost, lifetime, and thin profile and panel flexibility. The strengths and weaknesses of each technology are analyzed, and their future perspectives are discussed.
