COMPUTER DISPLAY SET AN/UYQ-21(V)
The Computer Display Set AN/UYQ-21(V) is the
latest display system in the Navy. It is installed on the
newer ships and is replacing older AN/UYA-4(V)
systems as part of the new threat upgrade. The
AN/UYQ-21(V) system is also configured according
to the mission of the ship. A typical configuration
could include tactical display consoles, display control
consoles, and large screen projection displays. The
system also offers expanded symbol sets and locally
generated programmable symbols.
As with the AN/UYA-4(V) system, the
AN/UYQ-21(V) system provides a real-time picture
of the tactical situation.
SUMMARY-BASIC DISPLAY DEVICES AND
SYSTEMS
In this chapter, you were introduced to the basic
element of most display systems, the CRT. You were
also introduced to the two display systems the Navy is
currently using.
The following information
summarizes some of the important points you should
have learned.
CATHODE-RAY
TUBE
(CRT)— The
cathode-ray tube (CRT) is the focal point in most
display devices. It provides a visual display of data
for the operator to interface with the computer. The
CRT has three functional areas: a phosphor coated
screen, an electron gun, and a deflection system.
PHOSPHOR SCREEN— The screen or face of the
CRT is coated with phosphor, which glows when
bombarded with electrons.
ELECTRON GUN– The electron gun in a CRT is
the source of the electron beam. The electron gun
also contains the control circuitry for the unblinking
and focusing of the beam.
CRT DEFLECTION SYSTEMS– Electromag-
netic deflection and electrostatic deflection are the
