I was Explained through diagrams mentioned below.

Logic diagrams:

Seven Segment Displays This presentation will demonstrate how A seven-segment display can be used to display the decimal numbers 0-9 and some alpha characters. A common anode seven-segment display works. • A common cathode seven-segment display works. • To select the resistor value for a seven-segment display. 12:19 8.8.8.8.
