2-Digit 7-Segment Thru-Hole Display

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

The 2-Digit 7-Segment Thru-Hole Display is a fundamental component in the field of electronic displays. It is a type of LED (Light Emitting Diode) display that is widely used in various electronic devices to display numerical information. These displays are characterized by their ability to show two digits, which make them ideal for applications such as clocks, meters, and calculators. In this article, we will delve into the details of the 2-Digit 7-Segment Thru-Hole Display, exploring its design, applications, and significance in the industry.

Design and Construction

The 2-Digit 7-Segment Thru-Hole Display consists of two sets of seven LED segments arranged in a common anode or common cathode configuration. Each segment is designed to represent a digit, with the ability to display numbers from 0 to 9. The common anode or cathode configuration refers to whether the common terminal of the LED segments is connected to the positive or negative voltage supply, respectively. The segments are typically made of a semiconductor material such as gallium arsenide (GaAs) or gallium phosphide (GaP), which emits light when an electric current is passed through them. The display is mounted on a printed circuit board (PCB) and can be connected to the circuit using either through-hole or surface-mount technology. The 7 segments are named as follows: A, B, C, D, E, F, and G. Each segment corresponds to a different part of the digit. For example, to display the number 1, only the top segment (A) is lit. To display the number 2, segments B, C, E, and D are lit, and so 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 set of features and specifications. Some of the common types include: 1. Common Anode 2-Digit 7-Segment Display: In this configuration, the common terminal of all the segments is connected to the positive voltage supply. To light up a segment, the corresponding cathode is grounded. 2. Common Cathode 2-Digit 7-Segment Display: Here, the common terminal of all the segments is connected to the negative voltage supply. To light up a segment, the corresponding anode is grounded. 3. Reverse Polarity 2-Digit 7-Segment Display: This type has a combination of common anode and common cathode segments, allowing for more complex display capabilities. 4. Color 2-Digit 7-Segment Display: These displays incorporate color LEDs, allowing for the display of color information along with numerical data.
