Functions of the NT31/NT31C Section 1-2
“Library data” are combinations of fixed display graphics registered as a single
graphic. They are registered in advance and as many as required can be dis-
played at any position on the screen.
Since it is generated by combining graphics, library data has a small data size.

Lamps
These are graphics whose display status changes in accordance with the states
of bits at the host. Squares, circles, sectors and polygons can be used for lamps
(normal (standard) lamps). In accordance with the status of the host bit, they
can be lit (displayed in reverse video) or flashed (repeated alternation between
normal and reverse video display states).
Lamps can also display different image/library data for the ON and OFF states of
the host bit (such lamps are called “image/library lamps”).
