AMOLED vs. VA
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
AMOLED
VA
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.
VA (Vertical Alignment) panels deliver the highest contrast ratio of the common LCD types -- commonly 3000:1 to 5000:1 on advanced variants, versus roughly 1000:1 for TN and IPS -- at the cost of slower pixel response, especially in dark scenes.
