display
(foldoc) | display
1. monitor.
2. A vector of pointers to activation records.
The Nth element points to the activation record containing
variables declared at lexical depth N. This allows faster
access to variables from outer scopes than the alternative
of linked activation records (but most variable accesses are
either local or global or occasionally to the immediately
enclosing scope). Displays were used in some ALGOL
implementations.

bitmap display
(foldoc) | bitmap display
bitmapped display
A computer output device where each pixel
displayed on the monitor screen corresponds directly to one
or more bits in the computer's video memory. Such a
display can be updated extremely rapidly since changing a
pixel involves only a single processor write to memory
compared with a terminal or VDU connected via a serial
line where the speed of the serial line limits the speed at
which the display can be changed.
Most modern personal computers and workstations have
bitmap displays, allowing the efficient use of {graphical user
interfaces}, interactive graphics and a choice of on-screen
fonts. Some more expensive systems still delegate graphics
operations to dedicated hardware such as {graphics
accelerators}.
The bitmap display might be traced back to the earliest days
of computing when the Manchester University Mark I(?)
computer, developed by F.C. Williams and T. Kilburn shortly
after the Second World War. This used a storage tube as its
working memory. Phosphor dots were used to store single
bits of data which could be read by the user and interpreted
as binary numbers.

"graphics"? What was the resolution?]

braille display
(foldoc) | braille display
refreshable braille display
refreshable display
(Or "refreshable braille display", "refreshable
display") An electromechanical device that renders braille
with tiny, independently controlled pins used to represent the
state of dots in braille cells. Each pin, in its "on" state,
raises above the top of its hole in the screen; in its "off"
state, it drops below the top of its hole. Older systems used
tiny solenoids to control the state of the pins; modern
systems are piezoelectric.
Typical dimensions of a braille display are 1 line of 40
cells, each cell of two-by-eight dots.

display hack
(foldoc) | display hack
A program with the same approximate purpose as a
kaleidoscope: to make pretty pictures. Famous display hacks
include munching squares, smoking clover, the BSD Unix
"rain(6)" program, "worms(6)" on miscellaneous Unixes, and the
X "kaleid(1)" program. Display hacks can also be
implemented without programming by creating text files
containing numerous escape sequences for interpretation by a
video terminal; one notable example displayed, on any VT100, a
Christmas tree with twinkling lights and a toy train circling
its base. The hack value of a display hack is proportional
to the aesthetic value of the images times the cleverness of
the algorithm divided by the size of the code. Synonym
psychedelicware.

Display Screen Equipment
VDU
(VDU, or "video terminal", "video display
terminal", VDT, "display terminal") A device incorporating a
cathode ray tube (CRT) display, a keyboard and a {serial
port}. A VDU usually also includes its own display
electronics which store the received data and convert it into
electrical waveforms to drive the CRT.
VDUs fall into two categories: dumb terminals and
intelligent terminals (sometimes called "programmable
terminals").
Early VDUs could only display characters in a single preset
font, and these were confined to being layed out in a
rectangular grid, reproducing the functionality of the
paper-based teletypes they were designed to replace.
Later models added graphics facilities but were still driven
via serial communications, typically with several VDUs
attached to a single multi-user computer. This contrasts with
the much faster single bitmap displays integrated into most
modern single-user personal computers and workstations.
The term "Display Screen Equipment" (DSE) is used almost
exclusively in connection with the health and safety issues
concerning VDUs.

display standards
video display standard
IBM and others have introduced a
bewildering plethora of graphics and text display standards
for IBM PCs. The standards are mostly implemented by
plugging in a video display board (or "graphics adapter")
and connecting the appropriate monitor to it. Each new
standard subsumes its predecessors. For example, an EGA
board can also do CGA and MDA.
With the PS/2, IBM introduced the VGA standard and built
it into the main system board motherboard. VGA is also
available as a plug-in board for PCs from third-party vendors.
Also with the PS/2, IBM introduced the 8514 high-resolution
graphics standard. An 8514 adapter board plugs into the PS/2,
providing a dual-monitor capability.
Graphics software had to support the major IBM graphics
standards and many non-IBM, proprietary standards for
displays. Either software vendors provided display drivers
or display vendors provided drivers for the software package.
In either case, switching software or switching display
systems was fraught with compatibility problems.

but only a few millimeters thick. They use a large array of
fine metal tips or carbon nanotubes (which are the most
efficient electron emitters known), to emit electrons through
a process known as field emission. Many of these are behind
each phosphor dot so FEDs do not display dead pixels like LCDs
even if 20% of the emitters fail. Sony is researching FED
because it is the flat-panel technology that comes closest to
matching the picture of a CRT.

LCD
(LCD) An electro-optical device used to display
digits, characters or images, commonly used in digital
watches, calculators, and portable computers.
The heart of the liquid crystal display is a piece of {liquid
crystal} material placed between a pair of transparent
electrodes. The liquid crystal changes the phase of the
light passing through it and this phase change can be
controlled by the voltage applied between the electrodes.
If such a unit is placed between a pair of plane polariser
plates then light can pass through it only if the correct
voltage is applied. Liquid crystal displays are formed by
integrating a number of such cells, or more usually, by using
a single liquid crystal plate and a pattern of electrodes.
The simplest kind of liquid crystal displays, those used in
digital watches and calculators, contain a common electrode
plane covering one side and a pattern of electrodes on the
other. These electrodes can be individually controlled to
produce the appropriate display. Computer displays, however,
require far too many pixels (typically between 50,000 and
several millions) to make this scheme, in particular its
wiring, feasible. The electrodes are therefore replaced by a
number of row electrodes on one side and column electrodes on
the other. By applying voltage to one row and several columns
the pixels at the intersections are set.
The pixels being set one row after the other, in {passive
matrix} displays the number of rows is limited by the ratio of
the setting and fading times. In the setup described above
(known as "twisted nematic") the number of rows is limited
to about 20. Using an alternative "supertwisted nematic"
setup VGA quality displays (480 rows) can be easily built.
As of 1995 most notebook computers used this technique.
Fading can be slowed by putting an active element, such as a
transistor, on the top of each pixel. This "remembers" the
setting of that pixel. These active matrix displays are of
much better quality (as good as CRTs) but are much more
expensive than the passive matrix displays.
LCDs are slimmer, lighter and consume less power than the
previous dominant display type, the cathode ray tube, hence
their importance for portable computers.

passive matrix display
(foldoc) | passive matrix display
A type of liquid crystal display which relies on
persistence to maintain the state of each display element
(pixel) between refresh scans. The resolution of such
displays is limited by the ratio between the time to set a
pixel and the time it takes to fade.
Contrast active matrix display.

refreshable braille display

refreshable braille display
refreshable display
(Or "refreshable braille display", "refreshable
display") An electromechanical device that renders braille
with tiny, independently controlled pins used to represent the
state of dots in braille cells. Each pin, in its "on" state,
raises above the top of its hole in the screen; in its "off"
state, it drops below the top of its hole. Older systems used
tiny solenoids to control the state of the pins; modern
systems are piezoelectric.
Typical dimensions of a braille display are 1 line of 40
cells, each cell of two-by-eight dots.
