Question

Describe the need of refreshing in multiplexed display mode

Answer 1

Multiplexed displays are electronic display devices 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 oriented 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
