Product Description

A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for
displaying decimal numerals that is an alternative to the more complex dot-matrix displays. Seven-segment
displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying
numerical information. The idea of the seven-segment display is quite old. In ***0, for example, a seven
segment display illuminated by incandescent bulbs was used on a power-plant boiler room signal panel.
