|Hewlett Packard 1345A Other|
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.
