D40571-M LED Dot Matrix Display – Introduction
The D40571-M is a compact LED dot matrix display module manufactured by the brand TOYO LED. It is designed for electronic devices that need to display numbers, characters, or simple graphics using a grid of light-emitting diodes.
Key Overview
- Matrix size: 5 columns × 7 rows (35 LEDs total)
- Display type: Single-color LED dot matrix
- Package: Through-hole module for PCB mounting
- Pins: 14 pins for row and column control
- Typical use: Microcontroller-based displays
How It Works
The display is arranged as a 5×7 LED grid. Each LED is located at the intersection of a row and a column. By controlling which rows and columns receive current, specific LEDs light up to form characters or patterns.
For example:
- Turning on certain LEDs can create letters (A–Z)
- Lighting specific dots can display numbers (0–9)
- Multiple modules can be combined to create scrolling text displays
Internal Structure
Inside the module:
- LEDs are wired in a matrix configuration.
- The pins correspond to row lines and column lines.
- A microcontroller or driver IC scans the rows/columns rapidly to display stable characters.
Common Applications
This type of LED matrix is widely used in:
- Digital clocks
- Electronic scoreboards
- Industrial control panels
- Microcontroller projects (Arduino, PIC, STM32)
- Information displays and signage
Advantages
✔ Compact and easy to mount
✔ Low power consumption
✔ Simple interface with microcontrollers
✔ Expandable for larger displays
