Terms

The following terms may appear in this user’s guide.

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.
