A
active-matrix display
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 computers because of its
shallow depth and high-quality color. Active-matrix displays
are viewable from wider angles than most passive-matrix
displays.
—A device that provides a compatible connection
adapter
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)
supplied to residential and commercial wall outlets. AC
reverses its direction at regular intervals. Compare
Current (DC)
