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 widely used electronic display component that plays a crucial role in various applications, ranging from simple calculators to complex industrial systems. It is designed to display two digits of numerical information, typically in a clear and legible format. This article aims to provide an in-depth introduction to the 2-Digit 7-Segment Thru-Hole Display, covering its working principle, applications, advantages, and future trends.
Working Principle
The 2-Digit 7-Segment Thru-Hole Display operates on the principle of the 7-segment display, which is a common type of electronic display device. It consists of seven individually controllable segments that can be turned on or off to form different numbers and characters. The segments are usually arranged in a rectangular pattern, forming a complete number from 0 to 9.
Each segment is connected to a control circuit, which allows it to be activated or deactivated based on the input signal. When a segment is activated, it emits light, making the corresponding part of the number visible. By selectively turning on or off the segments, the display can show any two-digit number.
Components of a 2-Digit 7-Segment Thru-Hole Display
A typical 2-Digit 7-Segment Thru-Hole Display consists of the following components:
1. 7-Segment Array: The array of seven segments that form the digits.
2. Common Anode or Cathode: Depending on the design, the segments can be either common anode or common cathode. In a common anode display, the segments are connected to the positive voltage, and the digits are illuminated by grounding the required segments. Conversely, in a common cathode display, the segments are connected to the negative voltage, and the digits are illuminated by applying a positive voltage to the required segments.
3. Driver Circuit: The circuit that controls the activation of the segments based on the input signal.
4. Mounting Holes: The thru-hole mounting holes that allow the display to be mounted onto a PCB or other electronic devices.
5. Cable or Connector: The cable or connector that connects the display to the control circuit.
