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

3-Digit 7-Segment Thru-Hole Display has become an essential component in the field of electronic devices. This article aims to provide a comprehensive introduction to this topic, covering its definition, working principle, applications, and market trends. With the rapid development of technology, 3-Digit 7-Segment Thru-Hole Display has been widely used in various industries, playing a significant role in the modern electronic era.

Definition and Classification

A 3-Digit 7-Segment Thru-Hole Display is an electronic display device that uses seven segments to represent numbers, letters, or symbols. It is named after the seven segments that make up the display, which can be divided into three groups of three segments. Each group is responsible for displaying one digit, hence the name “3-Digit 7-Segment Thru-Hole Display.” These displays are commonly used in various electronic devices, such as calculators, meters, and clocks.

According to the different types of materials and technologies used, 3-Digit 7-Segment Thru-Hole Displays can be divided into several categories:

1. Common Cathode (CC) Display: In this type of display, the segments are connected to the positive voltage, and the common cathode is connected to the ground. When a segment is turned on, it emits light.
2. Common Anode (CA) Display: In contrast, the segments in this type of display are connected to the ground, and the common anode is connected to the positive voltage. When a segment is turned on, it emits light.
3. Dual-In-Line Package (DIP) Display: This type of display has pins on both sides, which are easy to connect to the circuit.
4. Surface-Mount Device (SMD) Display: SMD displays are mounted on the surface of the circuit board, which can save space and improve the device’s stability.

Working Principle

The working principle of a 3-Digit 7-Segment Thru-Hole Display is based on the seven-segment structure. Each segment can be turned on or off independently, which allows the display to show different numbers, letters, or symbols.

When a digit needs to be displayed, the corresponding segment pins are connected to the control circuit, and the control circuit drives the corresponding segment to emit light. The seven segments can be turned on or off in various combinations to display different characters. For example, to display the number “1,” only the upper left and lower right segments need to be turned on.

The control circuit can be divided into two types: analog and digital. Analog control circuits are mainly used in simple applications, while digital control circuits are more commonly used in complex applications.

Applications

3-Digit 7-Segment Thru-Hole Displays are widely used in various fields due to their simplicity, low cost, and high readability. The following are some typical applications:
