A seven-segment display is widely used for displaying decimal numbers from 0 to 9. It consists of seven segments of light-emitting diodes (LEDs) which are assembled like numerical 8. They are most commonly used in electronic devices like digital clocks, timers and calculators to display numeric information. A single-digit 7-segment display is an electronic part used to show one number at a time, from 0 to 9. It has 7 LED segments shaped like the number 8. Each segment can be turned on or off to form any number. Some versions also have a decimal point (dot) for showing decimal values.
