actual image size

The size of the display on the screen is dependent upon the

signals provided by the video card. The displayable

diagonal measurement can vary, depending on how the

graphics mode is generated and how the monitor responds

to the characteristics of the video signal.

aperture grille

Aperture grille technology employs a series of thin, closely

spaced vertical wires to isolate pixels horizontally. The

pixels are separated vertically by the nature of the scan

lines (beams) used to compose the image.

bandwidth

A measure of the display performance of a monitor.

Expressed in MHz, bandwidth is the number of dots that

can be displayed in a line per second. More strictly, it is the

frequency response of the system between points where the

signal level falls to a specified percentage of its maximum

value (usually 50% or 75%). In principle, the greater the

bandwidth, the better the monitor—although the quality of

the picture tube is often the limiting factor affecting display

performance, and for many standard monitors there is little

point in increasing the bandwidth beyond a certain point.

Typical bandwidths for monitors (Spring 2003) are as

follows:

VGA monitors: 18 MHz

FGA+ monitors: 35 MHz

CAD monitors: 100 MHz

Bauart

Component products can be Bauart certified by TÜV for

expected safety concerns, meaning evaluation to German

and European Union standards for building into other

equipment. Typical component products are touchscreens,

controllers, and kiosk or frame touchmonitors.

brightness

Light output measured at the faceplate of the CRT; typically

measured in footlamberts (Fl). A minimum brightness level

of 20 Fl when viewing a full-sized page is considered

acceptable.

CD-ROM

Compact Disc Read-Only Memory. A CD-ROM is any

compact disc that contains computer data. "ROM" means

that you cannot save information onto these discs. These

discs can hold huge amounts of data (up to 640

megabytes). If there is a large amount of data on a CD-

ROM, then it is usually impractical to copy the data onto

the hard disk; in this case, you must insert the disc into the

drive whenever you want to use the data. CD-ROM may

also refer to the drive used to read these discs.

The CE (Conformite Europeene) marking on end products

indicates compliance with all applicable directives. For

information technology equipment (ITE) this typically

means Low Voltage Directive 73/23/EEC (LVD), and the

EMC Directive 89/336/EEC. Typical end products are

desktop touchmonitors.

Components typically do not carry the European Union’s

CE marking. Properly applied, they will comply with the

LVD and EMC Directives. Typical component products are

touchscreens, controllers, and kiosk touchmonitors. Refer

to the product Declaration of Conformity (DOC) for test

levels.

contrast

The ratio between the maximum and the minimum

brightness of the display.

contrast control

A manual gain control for a monitor, affecting both

luminance and contrast.

C-Tick

A trademark registered to the Australian Communications

Authority, indicating compliance with the electromagnetic

radiation emissions limits of Australia and New Zealand.

CRT

Cathode ray tube. Also known as picture tube or screen. A

picture tube in a TV is also a CRT.

DDC

Display Data Channel. A VESA standard for communication

between a monitor and a video adapter. Using DDC, a

monitor can inform the video card about its properties,

such as maximum resolution and color depth. The video

card can then use this information to ensure that the user is

presented with valid options for configuring the display.

DDC2B

VESA standard bidirectional digital data channel between

the display and the host. The host initiates data transfer by

reading the EDID from a memory location in the display.
