AMOLED vs. QD-OLED
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
AMOLED
QD-OLED
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.
QD-OLED combines a blue OLED light source with a quantum-dot color-conversion layer, an approach Samsung Display commercialized in 2022 -- as distinct from LG's older WOLED, which uses a white OLED source filtered through color filters. Reviewers report wider color volume as the main practical benefit.
