2. Product Features
High Luminous Intensity & Reliability: Bright, consistent light output ensures readability in different environments; stable component quality minimizes failure risks.
Low Power Consumption: Operates at a low forward current (5-10mA/LED), making it ideal for battery-powered devices or energy-saving home appliances.
Stable Performance: Maintains consistent light output and electrical properties across long-term use, avoiding flickering or dimming.
Long Lifetime: High-quality LED chips and epoxy materials extend the service life, reducing the need for frequent replacements.
Easy Assembly: Standard dimensions and common cathode polarity simplify integration into PCBs (printed circuit boards) or device panels, compatible with automated assembly processes.
IC Compatible: Works seamlessly with common integrated circuits (ICs) for display driving, reducing circuit design complexity.
RoHS Certified: Complies with the Restriction of Hazardous Substances Directive, ensuring environmental friendliness and safety for end-users.
3. Applications
This LED display is widely used in home electronic appliances and temperature/energy control systems, including but not limited to:
Air conditioner control panels (for displaying temperature, mode, or fan speed)
Refrigerator indicators and control panels (for showing temperature, door status, or ice-making mode)Cooling and heating control devices (e.g., electric heaters, dehumidifiers, or smart thermostats)Other small home appliances requiring clear digital or status indication (e.g., rice cookers, water heaters)
