2-Digit 7-Segment Thru-Hole Display: Ultimate Guide & Reviews

Introduction to 2-Digit 7-Segment Thru-Hole Display

What is a 2-Digit 7-Segment Thru-Hole Display?

A 2-Digit 7-Segment Thru-Hole Display is an electronic device used to display numerical information, typically two digits, on a 7-segment display. The display is designed with a transparent or translucent casing that allows light to pass through, making it easy to read in both day and night conditions. It is widely used in various electronic devices such as calculators, clocks, meters, and other consumer electronics.

The 7-segment display is composed of seven individual segments, each representing a different part of a digit. When a segment is turned on, it emits light, allowing the digit to be visible. In a 2-Digit 7-Segment Thru-Hole Display, two sets of these segments are used to display two digits simultaneously.

How Does a 2-Digit 7-Segment Thru-Hole Display Work?

A 2-Digit 7-Segment Thru-Hole Display works by using a combination of transistors and resistors to control the segments. The display is connected to a microcontroller or a logic circuit, which sends signals to the display to turn on the appropriate segments for the desired digit.

Each segment is connected to a separate pin on the display, and the microcontroller or logic circuit controls the voltage on these pins to turn the segments on or off. By selectively turning on the segments, the display can show any two-digit number.

The 7 segments are arranged in a specific pattern to represent the digits 0 to 9. For example, to display the number 1, only the top horizontal segment and the middle vertical segment are turned on. To display the number 8, all seven segments are turned on.

Types of 2-Digit 7-Segment Thru-Hole Displays

There are several types of 2-Digit 7-Segment Thru-Hole Displays available in the market, each with its own features and specifications. Some of the common types include:

1. Common Anode Display: In this type of display, the segments are connected to the positive voltage, and the common cathode pin is grounded. To turn on a segment, the corresponding pin is grounded.

2. Common Cathode Display: In this type of display, the segments are connected to the ground, and the common anode pin is connected to the positive voltage. To turn on a segment, the corresponding pin is connected to the positive voltage.

3. Reverse Common Anode Display: This is a variation of the common anode display, where the segments are connected to the ground, and the common anode pin is grounded. To turn on a segment, the corresponding pin is connected to the ground.

4. Reverse Common Cathode Display: This is a variation of the common cathode display, where the segments are connected to the positive voltage, and the common cathode pin is connected to the ground. To turn on a segment, the corresponding pin is connected to the ground.
