A 5×7 Square Dot Matrix Display is an LED matrix display component used to form characters, numbers, symbols and simple patterns through a grid of illuminated dots. The display uses a 5-column by 7-row arrangement, giving a total of 35 dot positions for character formation.
Unlike seven segment displays, which are mainly used for numeric digits, a 5×7 dot matrix display allows more flexible character representation. It can display alphabets, numbers, symbols, short messages and scrolling text when controlled through a suitable circuit.
Alfa Electronic Components supplies 5×7 Square Dot Matrix Displays for industrial electronics, embedded systems, instrumentation, telecom equipment, control panels, message display systems and custom LED display assemblies.
Square Dot Character Display
The square dot construction gives characters a fuller and more block-style appearance compared to round dot matrix displays. This can be useful where bold character visibility, sharper text appearance or a stronger visual display effect is required.
The display can be used to show:
- Alphabets
- Numbers
- Short text
- Status codes
- Symbols
- Direction marks
- Simple icons
- Scrolling messages
- Equipment information
The final character style depends on the software pattern, row-column scanning method and display-driving circuit used in the product.
Available Dot Size Range
The range includes dot sizes from 2.5 × 3.2 mm to 10 mm.
Compact dot sizes such as 2.5 × 3.2 mm, 3 × 3 mm, 3.45 × 3.45 mm and 3.5 × 3.5 mm are suitable for small instruments, embedded display modules and compact PCB-based electronic products.
Larger dot sizes such as 3 × 4 mm, 4 × 4 mm and 10 mm are suitable for bigger display panels, message indication systems and applications where characters must be more visible.
Available Body Height Range
Alfa Electronic Components offers 5×7 Square Dot Matrix Displays in body heights from 0.7 inch to 4.0 inch.
The 0.7 inch and 1.0 inch displays are suitable for compact electronic equipment and small character modules.
The 1.2 inch and 1.5 inch displays provide a practical balance between size and readability.
The 2.0 inch, 3.0 inch and 4.0 inch variants are suitable for larger display panels, industrial indication systems, scrolling text displays and equipment message displays.
Suitable for Text, Symbol and Message Applications
A 5×7 square dot matrix display is useful where the product needs more flexibility than a numeric display. It can be used in systems where letters, symbols, short messages, status codes or scrolling information need to be shown clearly.
This makes it suitable for industrial control panels, telecom equipment, embedded systems, token displays, queue displays, machine indicators and custom LED message boards.
PCB Mount Display Component
These displays are designed for PCB-mounted applications. Buyers should confirm the dot size, body height, body dimensions, pinout, electrical configuration and latest approved drawing before finalising the PCB layout.
Since dot matrix displays require row-column control, the driver circuit should be planned according to the selected model, brightness requirement, scanning method and character display requirement.
