n. A liquid crystal display (LCD) made from a large array of liquid crystal cells using active-matrix technology. The active matrix is a method of addressing an array of simple LC cells--one cell per pixel. In its simplest form there is one thin-film transistor (TFT) for each cell. Active-matrix displays are used most frequently in laptop and notebook computers because of their thin width and are notable for their high-quality color displays, which are viewable from all angles, unlike passive-matrix displays. Also called TFT, TFT display, TFT LCD. See also liquid crystal display, TFT. Compare passive-matrix display.
