A active-matrix display — A liquid crystal display (LCD) made
from an array of liquid crystal cells using active-matrix
technology. Also known as a “TFT display,” in its simplest form
there is one thin film transistor (TFT) for each cell. This type of
display works well with notebook computers because of its
shallow depth and high-quality color. Active-matrix displays are
viewable from wider angles than most passive-matrix displays.
adapter — A device that provides a compatible connection
between two units. For example, the computer’s internal display
adapter receives information from the software and translates it
into images on the screen. An adapter can take a number of
forms, from a microprocessor to a simple connector. An
intelligent adapter (one that is capable of doing some processing)
may also be called a controller.
alternating current (AC) — The type of power usually supplied to
residential and commercial wall outlets. AC reverses its direction
at regular intervals. Compare direct current (DC).
