Passive Matrix
An LCD technology that uses pixels which are
made up of RGB (Red, Green, Blue). Passive pixels are at rest
until activated by pulses of signals. Passive matrix has a slower
response time causing moving objects to streak or ghost unlike
active matrix.
Pixel
A definable location on a display screen that consists of
multiple or single triad of dots (red, green, and blue). A comput-
er picture is typically composed of a rectangular array of pixels
(i.e. 300 x 450). The resolution of a picture is expressed by the
number of pixels in the display. For example, a picture with 560 x
720 pixels is much sharper than a picture with 275 x 400 pixels.
Plug & Play (PnP)
A term used to indicate that a device can be
installed with no setup (program installation, software settings,
etc.). Many devices require software, setting changes, or boot
after installation. This is not true of a plug and play device.
Projector
A presentation device that has its own light source
built-in, sometimes called an all-in-one projector. Plug the com-
puter into the unit and project the computer’s image onto a
screen or wall.
