7 Segment Display / Digital Tube Segment Display / 2Bit / 3Bit / 4Bit - (RED)

A 7-segment display is an electronic display device used for displaying decimal numerals and some alphabetic characters. It is commonly used in digital clocks, calculators, and other devices that display numerical information.
Structure:

A typical 7-segment display consists of seven LEDs (light-emitting diodes) arranged in a rectangular fashion. Each of the seven segments can be illuminated individually to create a variety of numbers and some letters.

The segments are named A through G, and sometimes there is an eighth segment for the decimal point (DP).
How It Works:

Each segment in the display is controlled individually. By turning on the appropriate combination of segments, the display can represent the desired numeral or character. For example:

* To display the numeral "8", all seven segments (A, B, C, D, E, F, and G) are illuminated.
* To display the numeral "1", only segments B and C are illuminated.

Common Configurations:

* Common Anode (CA): All the anodes (positive terminals) of the LEDs are connected together to a common point. To light up a segment, you apply a low voltage (ground) to the cathode (negative terminal) of the segment.

* Common Cathode (CC): All the cathodes (negative terminals) of the LEDs are connected together to a common point. To light up a segment, you apply a high voltage (positive) to the anode (positive terminal) of the segment.

Applications:

7-segment displays are widely used in:

* Digital clocks
* Electronic meters
* Calculators
* Microwave ovens
* Instrument panels
* Scoreboards

Advantages:

* Simple and easy to use
* Low power consumption
* Inexpensive
* Can display both numbers and some letters
