A 5×7 Round Bi Colour Dot Matrix Display is an LED matrix display component that combines character display capability with dual-colour visual indication. It uses a 5-column by 7-row dot matrix arrangement, allowing the display to form alphabets, numbers, symbols and simple patterns.
Unlike a standard single-colour dot matrix display, a bi colour dot matrix display can support two-colour indication in the same display format. This makes it useful when the product needs to show text or symbols along with status-based colour differentiation.
The display contains 35 round dot positions arranged in a 5×7 matrix. By controlling the dot pattern through a suitable driver circuit or microcontroller, the display can show characters, short codes, signs, symbols, arrows, simple icons and scrolling text.
Alfa Electronic Components supplies 5×7 Round Bi Colour Dot Matrix Displays for industrial electronics, embedded systems, instrumentation, control panels, telecom equipment, message display systems and custom LED display assemblies.
Bi Colour Character and Status Indication
The main advantage of a bi colour dot matrix display is that it can communicate both character information and colour-based status information.
It can help indicate:
- Normal and alert conditions
- Running and fault status
- Active and inactive modes
- Warning messages
- Process condition changes
- User attention requirements
- Equipment status messages
- Dual-colour scrolling text
The actual colour behaviour depends on the selected model, electrical configuration and display-driving circuit. Buyers should confirm the required colour combination and circuit compatibility before final selection.
Round Dot Matrix Format
The round LED dot design gives the display a clean and traditional character 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
- Simple icons
- Direction marks
- Scrolling characters
- Equipment messages
The final character appearance depends on the dot-mapping pattern, scanning method and software control used in the application.
Available Dot Size Range
The range includes dot sizes from 1.9 mm to 10 mm.
The 1.9 mm option is suitable for compact electronic products, small character modules and space-restricted PCB layouts.
The 3 mm options are suitable for instruments, embedded modules and control panels where a balance between compact size and readability is required.
The 5 mm and 10 mm variants are useful for larger message panels, industrial display boards and applications requiring improved visibility.
Available Body Height Range
Alfa Electronic Components offers 5×7 Round Bi Colour Dot Matrix Displays in body heights from 0.7 inch to 4.0 inch.
The 0.7 inch display is suitable for compact electronic devices and small PCB-mounted character indication.
The 1.2 inch and 1.5 inch displays provide practical visibility for instruments, controllers and embedded equipment.
The 2.0 inch and 4.0 inch variants are suitable for larger panels, message displays, industrial indication systems and display boards where visibility is more important.
Suitable for Text, Symbol and Alert Applications
A 5×7 Round Bi Colour Dot Matrix Display is suitable when the product needs flexible character display with colour-based meaning. It can show letters, numbers and symbols while using colour to highlight normal, warning, fault or mode-related conditions.
This makes it useful for industrial control panels, telecom equipment, embedded systems, token displays, queue displays, machine indicators, custom message displays and alert-based display modules.
PCB Mount Display Component
These displays are suitable for PCB-mounted electronic products. Buyers should confirm dot size, body height, body dimensions, pinout, electrical configuration, colour combination and latest approved drawing before finalising PCB layout or production.
Since bi colour dot matrix displays require row-column control and colour control, the driver circuit should be planned carefully according to the selected model and application requirement.
