Traditional Multiplexing
Display multiplexing is very different from multiplexing used in data transmission, although it has the same basic principles. In display multiplexing, the data lines of the displays are connected in parallel to a common bus on the microcontroller. Then, the displays are turned on and addressed individually. This allows one to use fewer I/O pins than it would normally take to drive the same number of displays directly.

Famous quotes containing the word traditional:
“Americans want action for their money. They are fascinated by its self-reproducing qualities if it’s put to work.... Gold-hoarding goes against the American grain; it fits in better with European pessimism than with America’s traditional optimism.”
—Paula Nelson (b. 1945)
