Information
The Hewlett-Packard Model
1345A is a 15.21 cm (6 in.)
Display Component, It produces vector graphics on its
display screen in response to digital commands from a user
prcessor. Because of its high resolution (2048 x 2048
addressable points), the
1345A can draw both straight and
curved lines (curvilinear vectors). Curved lines can be
accomplished by a series of short straight vectors. The
1345A draws all vectors in a picture by moving its display
beam at the same speed. This constant writing rate ensures a
picture of uniform brightness (short vectors do not become
brighter than long vectors). Erasing a waveform that
intersects other waveforms (vectors) will not leave blank
spaces at the intersections. At its faster drawing rate, and
at 60 Hz refresh rate, the
1345A can draw a picture that
contains up to 3226 inches of vectors. If the refresh rate
is slowed to 40 Hz (possible in some applications), then the
picture can contain up to 4838 inches of vectors. For
labeling or identification of soft-key functions, the 1345A
has a built-in set of ASCII characters. The
1345A receives
just one word from the user processor and all the vectors
necessary to form the character are automatically produced.
