A 5×7 Round Dot Matrix Display is a compact LED display component used to create readable characters, numbers and symbols using a matrix of illuminated dots. The display contains 5 vertical columns and 7 horizontal rows, giving a total of 35 LED dot positions.
Unlike seven segment displays, which are mainly designed for numeric digits, a 5×7 dot matrix display can form alphabets, numbers, symbols and basic graphic patterns. This makes it suitable for electronic products where character display or short-message indication is required.
Alfa Electronic Components supplies a range of 5×7 Round Dot Matrix Displays for industrial electronics, embedded systems, instrumentation, control panels and custom LED display assemblies. The available range includes compact sizes for small instruments and larger dot matrix displays for improved visibility.
Round Dot Character Display
The round LED dot construction gives the display a clean and traditional matrix appearance. Characters are created by lighting selected dots in the 5×7 grid.
This format is useful for displaying:
- Alphabets
- Numbers
- Short text
- Status codes
- Symbols
- Arrows and simple icons
- Scrolling characters
- Equipment messages
The actual character appearance depends on the driving circuit, dot-mapping pattern and software control used in the application.
Available Dot Size Range
The range includes dot sizes from 1.9 mm to 10 mm.
Smaller dot sizes such as 1.9 mm, 2.54 mm and 3 mm are suitable for compact instruments, embedded devices and space-restricted PCB layouts.
Medium and larger dot sizes such as 5 mm, 7.62 mm and 10 mm are suitable for display panels, message displays and applications where the character must be visible from a greater distance.
Available Body Height Range
Alfa Electronic Components offers 5×7 Round Dot Matrix Displays in body heights from 0.7 inch to 4.0 inch.
The compact 0.7 inch and 1.0 inch models are useful for small electronic devices, handheld instruments and PCB-based character indication.
The 1.2 inch and 1.5 inch options provide a practical balance between readability and product size.
The 2.0 inch, 3.0 inch and 4.0 inch variants are suitable for larger panels, equipment displays, industrial indication systems and message display applications.
Suitable for Text and Symbol Applications
A 5×7 dot matrix display is commonly selected when the product needs to show more than only numbers. It is useful where short words, letters, codes, abbreviations, symbols or scrolling text must be shown.
This makes it suitable for electronic instruments, telecom equipment, control systems, token systems, machine indicators, embedded modules and industrial display boards.
PCB Mount Display Component
These dot matrix displays are suitable for PCB-mounted electronic products. Buyers should confirm the body size, dot size, pinout, electrical configuration and latest technical drawing before finalising PCB layout or production.
Since dot matrix displays require row-column control, the driving circuit should be planned according to the selected model, required brightness and character-scanning method.
