AMOLED vs. Mini-LED
Comparing 2 standards across 12 specifications. 12 key differences identified.
AMOLED (Active-Matrix OLED) combines OLED's self-emissive pixels with a TFT active-matrix backplane -- the same one-transistor-per-pixel driving concept as TFT LCD, but switching light-emitting diodes instead of liquid-crystal light valves. It's the dominant OLED format in smartphones, mass-produced by Samsung starting in 2007.
Mini-LED is a backlight technology, not a panel type -- it uses thousands of LEDs roughly 0.1-0.2mm in size (versus 0.5-1mm for traditional LED backlights) arranged into hundreds or thousands of local-dimming zones behind an LCD panel of any type, improving contrast and reducing blooming. TCL commercialized it in TVs starting in 2019.
