Glossary

AMTFT: Acronym for Active Matrix Thin Film Transistor. This is the type of liquid crystal display

panel used in essentially all computer at panel displays today.

Calibrate: For touchscreens, “calibrate” is the common term for the process that is really

“video alignment.” A touchscreen and its controller have a coordinate system that are usually

not identical to the coordinate system of the video display of the host computer. By displaying

reference points on the MCI Touch Monitor (through the calibration program) and touching

those reference points, the MCI Touch Monitor coordinate system is scaled to that of the

computer.

Color temperature: Color temperature is a simplied way to characterize the spectral

properties of a light source, and is the temperature you would heat a theoretical “black body”

source to radiate light of the same visual color. For example, “low” color temperature, like

3200°K, implies warmer (more yellow/red) light, while “high” color temperature, like 9300°K,

implies a cooler (more blue) light. Daylight has the 3200°K temperature mentioned near dawn

and evening, and a higher one during the day. The standard unit for color temperature is the

Kelvin (K).

Contrast Ratio: The ratio of the luminance of the display of a full white image to a full black

image. This parameter is useful in determining the relative sharpness of two displays-a higher

contrast ratio usually implies a sharper image, especially when text is displayed.

Controller or Touchscreen controller: The electronics that actually process the touch on the

touchscreen and sends out a digital representation of that touch to the host computer.

Emulation: As used in display technology, emulation mode means an image displayed at a

non-native resolution. For your Preh MCI Touch Monitor and other 15” monitors, the common

emulation modes are 800 x 600 and 640 x 480. In emulation modes, a monitor cannot perfectly

display the image sent from the computer when the monitor pixel to image pixel ratio is not an

integral multiple.

Hub or USB hub: An electronic circuit that combines several USB signals into one.

Illuminance: The measure of how much luminous ux per unit area that impinges on a

particular surface, or how bright a point source of light appears to the eye. It is measured in

footcandles or in lux.

Kelvin: The scale of temperature measurement that begins at absolute zero. The increment of

temperature that one Kelvin represents is the same as that of the Celsius scale, but the scale

starts at -273.16°C. Thus 293°K is about 20°C or 68°F.

Keyboard emulation: Produces the same output as a keyboard, or a “keyboard wedge”

magnetic stripe reader.

Keyboard wedge: An MSR unit that connects to a computer keyboard port with a cable that

also connects the standard keyboard, thus a keyboard wedge.

LCD: Acronym for Liquid Crystal Display. The most common technology used in at computer

displays today. “Liquid crystal” molecules (a very complex chemical engineered for this function)

sandwiched between a combination of at glass color lters and polarizers, pass or block light

in response to electrical signals applied by the display electronics. The result is a very sharp,
