Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
TFT LCD
VA
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.
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.
