IPS vs. TFT LCD
Comparing 2 standards across 11 specifications. 11 key differences identified.
IPS (In-Plane Switching) panels offer the widest viewing angles of the common LCD types -- 178°/178° is standard -- and the most consistent color, making them the default for color-critical monitors and most phone LCDs, at a contrast ratio similar to TN's.
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.
