What is 7-segment?

A 7-segment display is a form of electronic display device that is commonly used in digital clocks, calculators, and other electronic devices that require numerical or alphanumeric displays. It consists of seven individual segments, each of which can be lit up independently to represent a different numeral or letter.

The segments themselves are typically arranged in a pattern that resembles the number 8, with a horizontal bar at the top and bottom and two vertical bars in the middle. By selectively lighting up certain segments, different numerals or letters can be displayed.

Many different types of 7-segment displays exist, including those with different numbers of segments (such as four or eight segments) and those that can display alphanumeric characters rather than just numbers. They can be made from materials such as LED or LCD panels and can be monochrome or multicolor.

7-segment displays are popular due to their simplicity and low cost, making them an ideal choice for many electronic devices. They are often used in combination with other display technologies to create more complex displays, such as those used in digital signage and scoreboards.
