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
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.
