Description

Devices included in this entry:

MSC 351-25977-009 light pipe module (5 digit numeric display, shown in thumbnail)
MSC 351-25977-010 light pipe module (8 digit numeric display)
MSC 351-35577-007 lamp and decoder module


Light pipe displays like this one are a close relative of the Dialco display pictured above, in that they use incandescent bulbs to light a seven segment pattern on a single plane surface. Unlike the comparatively economical Dialco display however, a light pipe display uses bundles of fiber optic cables to present a fixed bitmap image of a number. The display seen here is actually equipped with sixteen segment light pipe arrays, but the unused fiber optic cables have been covered with epoxy. Each plastic-encased driver module contains an Intersil 5600 read only ROM chip which functions as a character decoder for the individual lamps. Unlike the Dialco display above, the lamps in this device are non-replaceable.

The lamps in this display can be non-destructively replaced with 3mm LEDs by the modern electronics hobbyist, but the combination of non modular digit construction and awkward digit spacing make this device a poor choice for a project.
