Dithering
A computer graphics technique that takes advantage of the human eye’s
tendency to mix two colors that are adjacent to each other to produce smooth
boundary transitions. Dithering adds intermediate color values between two
or more boundaries, producing smoother, more natural look to 2D images or
3D objects.
Dot pitch
Dot pitch specifies the sharpness of a monitor’s display. It is measured in
millimeters (mm) and is the distance between the individual phosphor sub-
pixels in a CRT display or cells of the same color within an LCD display. The
smaller the number, the sharper the image. The most common dot pitches for
monitors range from .24 mm to .31 mm. Also, if a monitor with a .24 mm dot
pitch is set to its highest possible resolution, the pixel size will equal the dot
pitch. If the monitor is set to lower resolutions, the pixels will be comprised
of multiple dots.
DVI
Acronym for “Digital Video Interface,” a standard video connection used on
many current computer displays. There are three types of DVI connections:
DVI-A (analog), DVI-D (digital), and DVI-I (integrated, capable of either
analog or digital). It supports high-bandwidth video signals over 160 Hz, so it
is most often used for high-resolution displays.
EDTV
Acronym for “Enhanced Definition Television”, which produces better
television image quality than Standard Definition Television (SDTV).
Applicable to the NTSC broadcast format, EDTV displays are capable of
depicting the standard 480 horizontal scan lines in a non-interlaced format.
Instead it paints all of the scan lines in one pass, which is called progressive
scanning, a process which also removes the “jaggies” inherent in the
interlaced television signals.
