A 7 Segment LED Display is a electronic device that contains an array of 8 individual LEDs.

 

Each of the 8 segments that make up the display can be either be on the on state or the off state. Depending on which LEDs are lit determines the character which is displayed on the LED. The LED can be made to show a wide range of characters, including all numerical digits from 0-9.
