An 8×8 Round Dot Matrix Display is a compact LED matrix display component used to create characters, symbols, icons and simple graphic patterns using a grid of illuminated round dots. The display contains 8 vertical columns and 8 horizontal rows, giving a total of 64 dot positions.
Compared to 5×7 and 5×8 dot matrix displays, the 8×8 format provides more dot positions for character shaping, symbol design and basic graphic display. This makes it suitable for electronic products where the display needs to show more flexible visual information than a numeric seven segment display.
Alfa Electronic Components supplies 8×8 Round Dot Matrix Displays for industrial electronics, embedded systems, instrumentation, telecom equipment, control panels, message displays and custom LED display assemblies.
8×8 Matrix Format
The 8×8 matrix arrangement gives designers more flexibility for creating alphabets, numbers, symbols and simple graphic patterns. Each character or icon is formed by switching selected dots ON and OFF using a suitable driver circuit or microcontroller.
This format is useful for displaying:
- Alphabets
- Numbers
- Symbols
- Arrows
- Simple icons
- Short codes
- Equipment status
- Scrolling text
- Basic graphic patterns
- Machine or process indication
The final display output depends on the dot-mapping pattern, scanning method, driver circuit and software control used in the product.
Available Dot Size Range
The range includes dot sizes from 1.9 mm to 5.0 mm.
The 1.9 mm dot size is suitable for compact electronic devices, small embedded display modules and close-viewing applications.
The 3.0 mm and 3.7 mm dot sizes are suitable for instruments, control panels and display modules requiring a balance between compact size and readability.
The 4.8 mm and 5.0 mm dot sizes provide better visibility for larger indicators, equipment displays, message panels and industrial display applications.
Available Body Height Range
Alfa Electronic Components offers 8×8 Round Dot Matrix Displays in body heights from 0.8 inch to 2.3 inch.
The 0.8 inch display is suitable for compact PCB-mounted products and small symbol display modules.
The 1.2 inch and 1.5 inch displays are useful for electronic instruments, embedded systems and control panels.
The 1.8 inch, 2.0 inch and 2.3 inch displays are suitable for larger display panels, message indicators and industrial equipment requiring improved visibility.
Suitable for Character, Symbol and Graphic Applications
An 8×8 Round Dot Matrix Display is useful when the product needs more visual flexibility than a seven segment or 5×7 dot matrix display. It can be used for character display, icon indication, scrolling text, arrows, symbols and simple graphic outputs.
This makes it suitable for industrial control panels, telecom equipment, embedded systems, queue displays, token displays, machine status indicators, custom message displays and LED matrix display boards.
PCB Mount Display Component
These displays are designed for PCB-mounted applications. Buyers should confirm the dot size, body height, body dimensions, electrical configuration, pinout and latest approved drawing before finalising the PCB layout.
Since 8×8 dot matrix displays require row-column scanning, the circuit should be planned according to the selected model, brightness requirement, scanning method and display pattern requirement.
