A 5×8 Round Dot Matrix Display is an LED matrix display component used to create readable characters, numbers, symbols and simple patterns using a grid of illuminated dots. The display contains 5 vertical columns and 8 horizontal rows, giving a total of 40 dot positions for character formation.
Compared to a 5×7 dot matrix display, the 5×8 format provides an additional row, which can support better character shaping, extended symbol design and improved visual spacing depending on the driving pattern used. This makes it useful for electronic products where clearer character formation or slightly taller character structure is required.
Alfa Electronic Components supplies 5×8 Round Dot Matrix Displays for industrial electronics, embedded systems, telecom equipment, instrumentation, control panels, message displays and custom LED display assemblies.
5×8 Character Display Format
The 5×8 matrix arrangement allows the display to form alphabets, numbers, symbols and short codes using controlled dot patterns. Each character is created by switching selected dots ON and OFF through a suitable driver circuit or microcontroller.
This format is useful for displaying:
- Alphabets
- Numbers
- Short text
- Status codes
- Symbols
- Simple icons
- Equipment messages
- Scrolling characters
- Process or machine status information
The final character style depends on the dot-mapping pattern, scanning method and control software used in the application.
Available Dot Size Range
The range includes 3 mm, 5 mm and 10 mm dot sizes.
The 3 mm dot size is suitable for compact instruments, embedded devices, small character modules and control panels where PCB space is limited.
The 5 mm dot size provides better visibility for medium-size display panels, equipment indicators and message modules.
The 10 mm dot size is suitable for large display panels, industrial message boards and applications where the character must be visible from a greater distance.
Available Body Height Range
Alfa Electronic Components offers 5×8 Round Dot Matrix Displays in body heights of 1.4 inch, 2.4 inch and 4.8 inch.
The 1.4 inch model is suitable for compact electronic instruments and PCB-mounted character indication.
The 2.4 inch model is useful for medium-size equipment displays, industrial indicators and message panels.
The 4.8 inch model is suitable for larger display boards, industrial panels, sign systems and applications requiring improved long-distance visibility.
Suitable for Text, Symbol and Message Applications
A 5×8 Round Dot Matrix Display is suitable where the product needs to display characters or symbols instead of only numeric values. It is commonly used in systems where alphabets, short messages, codes or scrolling information must be shown clearly.
This makes it useful for telecom equipment, industrial control panels, embedded modules, machine indicators, token systems, queue systems, message display panels and custom LED display assemblies.
PCB Mount Display Component
These displays are suitable for PCB-mounted electronic products. Buyers should confirm body size, dot size, electrical configuration, pinout and latest approved drawing before finalising PCB layout or production.
Since dot matrix displays require row-column scanning, the driver circuit should be planned according to the selected model, brightness requirement, scanning method and required character display pattern.
