Description
Deinterlacer
Electronic component that converts an interlace video signal to
progressive scan.
Deinterlacing
Act of converting an interlace video signal to progressive scan.
Diagonal
The diagonal of a screen or flat panel can be computed by using
the Pythagorean theorem: squaring the width, squaring the height,
adding them together and taking the square root. A 100" diagonal
16:9 screen measures 49" high by 87" wide; a 100" diagonal 4:3
screen measures 60" high by 80" wide. Use the Projection Calculator
to get screen dimensions on all common aspect ratios.
Dichroic
A mirror or lens that reflects or refracts selective wavelengths of
light. Typically used in projector light engines to separate the lamps
"white" light into red, green, and blue light.
DICOM
A DICOM projector (Digital Imaging and Communications in
Medicine) provides the medical profession with the ability to simulate
21 different levels of grayscale in the rendering of X-rays, CAT scans,
MRIs and other medical imaging applications.
DisplayPort
DisplayPort is a digital display interface developed by the VESA. The
interface is primarily used to connect a video source to a display
device such as a computer monitor, though it can also be used to
transmit audio, USB, and other forms of data. DisplayPort can be used
to transmit audio and video simultaneously. The DisplayPort signal is
not directly compatible with DVI or HDMI
be used to adjust the signal levels and convert the connector style.
Distortion
A usually undesirable variation from an intended output caused by
the characteristics of a particular device.
Dithering
Method of displaying intermediate colours that don't exist in a limited
palette by using a pattern of small dots out of that palette.

DLP
DLP
technology from Texas Instruments
often referred to as DMD (Digital Micro-Mirrors). It consists of an
array of mirrors where each mirror represents a pixel element. For
example, a high-definition DLP
x 1080 pixel resolution would have over 2 million tiny mirrors. Each
mirror is attached to an electronically driven hinge that controls the
amount of coloured light that is reflected from the mirror into the
projection lens and onto a screen. Projection systems using DLP
technology use 1 to 3 DMD devices.
DMD
Digital Micromirror Device. Name of the actual imaging chip used in a
Texas Instruments DLP projection systems.
DNR
Digital Noise Reduction. A system that reduces picture noise by
comparing previous frames to the present and smoothing out what
appears to be noise to the algorithm. Helps reduce flickering in still
parts of a video image.
