Side-by-Side Comparison
Panel Types
AMOLED vs. TN
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
AMOLED
TN
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.
TN (Twisted Nematic) is the fastest and cheapest common LCD panel type, with response times as low as 1ms -- traded off against narrow, asymmetric viewing angles and noticeable color shift when viewed from above or below.
