Terms

The following terms may appear in this User’s Guide.

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 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)

application—A computer program that you use to perform

tasks of a specific type. Applications include word

processors, spreadsheets, and database management

systems. See also
