Side-by-Side Comparison
Panel Types
TFT LCD vs. TN
Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
TFT LCD
TN
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.
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.
