Multiplexed Display
Multiplexed displays are electronic displays where the entire display is not driven at one time. Instead, sub-units of the display (typically, rows or columns for a dot matrix display or individual characters for a character orientated display, occasionally individual display elements) are multiplexed, that is, driven one at a time, but the electronics and the persistence of vision combine to make the viewer believe the entire display is continuously active.
A multiplexed display has several advantages compared to a non-multiplexed display:
- Fewer wires (often, far fewer wires) are needed
- Simpler driving electronics can be used
- And both lead to reduced cost
- Reduced power consumption
Multiplexed displays can be divided into two broad categories:
- Character-oriented displays
- Pixel-oriented displays

Famous quotes containing the word display:
“Housekeeping is not beautiful; it cheers and raises neither the husband, the wife, nor the child; neither the host nor the guest; it oppresses women. A house kept to the end of prudence is laborious without joy; a house kept to the end of display is impossible to all but a few women, and their success is dearly bought.”
—Ralph Waldo Emerson (1803–1882)
