Seven Segment LED Displays provide a straightforward format for displaying measurements, counts, temperatures, settings, time and other numerical information.
Different electronic products require different numerical formats.
Alfa’s range extends from 1 Digit to 6 Digit 7 Segment LED Displays, giving OEM manufacturers multiple configurations to evaluate according to their product requirements.
OEM equipment is not limited to numerical information.
Alphanumeric Segment Displays and Dotmatrix Displays can support applications requiring letters, characters and symbols.
4 Digit and 6 Digit 7 Segment Clock Led Displays can be considered for electronic products incorporating clocks, timers or other time-based functions.
Arrow LED display up-down and Directional LED arrow display can support OEM products requiring dedicated visual direction indication.
Single Color LED Bar Graph and Multi Color LED Bar Graph provide display options for electronic equipment requiring a visual representation of levels or changing ranges.
Display selection should begin with the information the product needs to communicate and then consider the mechanical and electronic requirements of the equipment.
Determine what needs to appear on the equipment interface:
Numerical values → Seven Segment LED Displays
Time information → Clock LED Displays
Letters and numbers → Alphanumeric Segment Display
Characters and symbols → Dotmatrix Displays
Directional information → Arrow LED Displays
Levels and ranges → LED Bar Graphs
Visual equipment status → LED Light Bars / Single Digit Bi Color
For numerical applications, determine the maximum number of positions required.
Single or compact values → 1 Digit / 2 Digit 7 Segment Led Display
Measurement and controller values → 3 Digit / 4 Digit 7 Segment Led Display
Extended numerical values → 5 Digit / 6 Digit 7 Segment Led Display
Character height should correspond with the normal viewing distance of the finished equipment.
A compact handheld or panel-mounted instrument will have different requirements from equipment designed to be read from several metres away.
For applications requiring larger numerical characters, the Jumbo 7 Segment Display can be considered.
Display colour should be selected according to the product interface, required contrast, visual hierarchy and available product configuration.
Bi-colour and multi-colour display products can be considered where colour differentiation forms part of the user interface.
Before finalising a display, OEM manufacturers should consider:
Overall display dimensions
Character height
Number of digits
Decimal-point requirements
Pin configuration
PCB footprint
Available PCB space
Mounting arrangement
Driver circuit compatibility
Viewing angle
Front-panel opening
Equipment enclosure dimensions
Required display orientation
These factors help ensure that the selected display fits both the electrical and mechanical design of the finished product.
During product development, OEM manufacturers should evaluate the display alongside the PCB, enclosure and interface design.
Sharing drawings, dimensions, required display format or an existing sample can help identify a suitable display configuration for the application.
Standard display products may not always match the layout required by a new electronic product.
An OEM manufacturer may require several display elements within the same interface, such as:
Multiple Seven Segment digits
Numerical and character displays
Numerical display with status indicators
Clock and indicator combinations
Dotmatrix and numerical combinations
Bar Graph and numerical displays
Directional arrows
Bi-colour indicators
Application-specific display arrangements
Depending on the requirement, Alfa Electronic Components can discuss the application and help identify suitable standard components or possible custom display configurations.
Multiple Seven Segment digits
Numerical and character displays
Numerical display with status indicators
Clock and indicator combinations
Dotmatrix and numerical combinations
Bar Graph and numerical displays
Directional arrows
Bi-colour indicators
Application-specific display arrangements
To help identify an appropriate LED display for a new or existing electronic product, manufacturers can share available technical and application information such as:
Application / Equipment Type
Required Display Type
Number of Digits
Required Character Height
Display Dimensions
Display Colour
Common Anode / Common Cathode Requirement, where applicable
Decimal-Point Requirement
Pin Configuration
PCB Layout or Available PCB Space
Required Viewing Distance
Existing Display Part Number, if replacing a display
Existing Sample or Photograph
Technical Drawing, if available
Required Quantity
Providing more application information can make it easier to evaluate an appropriate display option.
