7-segment display(FND)

What you learn

Simulation Ages 12–16

See how a screen lights up tiny dots or beams to build a moving picture.

7-segment display, FND

Parts that place multiple LEDs to display numbers or hexadecimal characters are called Seven Segment Displays or FND (Flexible Numeric Displays). It can display all numbers from 0 to 9 with only seven LEDs. So, they are widely used in elevators, rice cookers, digital wall…

The single-digit FND has 10 pins (legs) in each of the 5 top and bottom. There are many pins, and it may look complicated, but it's only part of the eight LED legs.
