The light-emitting element normally takes the form of a diode so electricity will only flow in one direction, keeping the individual "row" and "column" lines of the matrix electrically isolated from each other. Whereas, Seven segment display is an electronic device which consists of seven Light Emitting Diodes (LEDs) arranged in a some definite pattern (common cathode or common anode type), which is used to display Hexadecimal numerals (in this case decimal numbers,as input is BCD i.e., 0-9). Copy of 7 Segment display using NAND gates only.
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.In senven segment displays the various segments of each character are connected in a two-dimensional matrix and will only illuminate if both the "row" and "column" lines of the matrix are at the correct electrical potential. NI Multisim Live lets you create, share, collaborate, and discover circuits and electronics online with SPICE simulation included. In the technique of multiplexing the entire display is not driven at one time.
