3-Digit 7-Segment Thru-Hole Display is a popular electronic component widely used in various applications for displaying numerical values. This article aims to provide an in-depth introduction to the 3-Digit 7-Segment Thru-Hole Display, including its structure, working principle, applications, and market trends.

Structure of 3-Digit 7-Segment Thru-Hole Display

The 3-Digit 7-Segment Thru-Hole Display consists of three 7-segment digits, which are interconnected and controlled by a common anode or common cathode circuit. Each digit is made up of seven LEDs, arranged in a specific pattern to form the numbers 0 to 9 and some additional characters. The 7-segment pattern is a standard configuration for displaying numerical values, where each segment represents a part of a digit. For example, segment a represents the top horizontal part of the digit, segment b represents the top vertical part, and so on. By turning on or off the LEDs corresponding to the segments, different numbers can be displayed. The 3-Digit 7-Segment Thru-Hole Display can be connected to a microcontroller or a driver circuit, which controls the current flowing through the LEDs to display the desired numbers or characters.

Working Principle of 3-Digit 7-Segment Thru-Hole Display

The working principle of the 3-Digit 7-Segment Thru-Hole Display is based on the operation of LEDs. When a current passes through an LED, it emits light. By controlling the current through each LED, the desired segment can be turned on or off, thereby displaying the desired number or character. The 3-Digit 7-Segment Thru-Hole Display uses a common anode or common cathode configuration. In a common anode display, the positive terminal of all LEDs is connected together and connected to the power supply. To turn on a segment, the corresponding cathode is grounded, allowing current to flow through the LED. In a common cathode display, the negative terminal of all LEDs is connected together and connected to the ground. To turn on a segment, the corresponding anode is grounded, allowing current to flow through the LED. The microcontroller or driver circuit sends signals to the display, controlling the current through each LED segment to display the desired number or character.
