bright display that is very thin, and uses little power, compared with a CRT, or tube-type
monitor.
Lux: The standard unit for illuminance is lux (lx) which is lumens per square meter (lm/m2).
1 lux=10.764 footcandle. Common room lighting is 100-1000 lux.
MSR: Acronym for Magnetic Stripe Reader. A device that reads information encoded in the
magnetic stripes on the back of a credit card, etc. The process is essentially identical to the
operation of a cassette tape player.
Native resolution: The resolution of a digital at panel display that actually describes how
many pixels are in each row and column of the display, and which is the resolution that the
display is optimized for. Your 15” Preh MCI Touch Monitor has a native resolution of 1024 x
768, which means that the LCD panel has 1024 pixels on each row, and has 768 rows. Each
element of video information received from the computer/display electronics is assigned to and
displayed by a specic location on the display panel-a pixel. At resolutions other than native
(see emulation) there is not a one-to-one correspondence between the video information
elements and the available pixels on the display. The display electronics must compensate for
this and cannot do a perfect conversion, thus emulation modes never look as good as images
displayed at the native resolution.
Nit: The standard unit of luminance is the candela per square meter (cd/m2), or Nit.
Pixel: Abbreviation for “picture element.” In an electronic display, the smallest complete
element of the picture that contains all possible colors and proper brightness. In your Preh MCI
Touch Monitor, one pixel of the LCD panel is a square “window,” with an area of about 0.3 x
0.3mm, containing three smaller windows that pass red, green or blue light at the appropriate
brightness in response to the video signal from the computer.
Polarizer: A thin glass or plastic sheet that lters out light rays of all but a specic orientation.
Light passing through such a sheet is thus polarized.
POS: Acronym for Point Of Sale.
Serial: A data transmission method where each bit (a “1” or “0”) of data is passed sequentially
(or serially) over a single data path (a wire…). The most common standard for this method
is called RS232. This is a very common method of interfacing peripheral equipment to older
computers. Today this method is increasingly replaced by another method called USB (see
below).
USB: Acronym for Universal Serial Bus. A common method for interfacing peripheral equipment
to computers. It has the advantages over other serial data transmission standards of higher
speeds and the ability to connect many devices to the same port on a computer.
VESA: Acronym for Video Electronics Standards Association. An industry trade group that
promotes interoperability standards within the video and computer industry. The VESA mounting
pattern (75mm) for displays is used by your Preh MCI Touch Monitor on the base and chassis,
allowing the monitor to be quickly attached to standard swing arms and mounting plates.
