AMOLED vs. TFT LCD
Comparing 2 standards across 7 specifications. 7 key differences identified.
Comparing:
AMOLED
TFT LCD
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.
TFT LCD refers to the active-matrix driving technology used by virtually all modern LCD panels -- one thin-film transistor per subpixel controlling its voltage -- not a specific alignment type like TN, VA, or IPS, which are all built on a TFT backplane.
