Super Bright Yellow Green 0.56" Triple Digit 7-Segment Common Cathode LED Display for Refrigerators

Product Overview

Introducing the Super Bright Yellow Green 0.56" Triple Digit 7-Segment Common Cathode LED Display—a refrigerator-optimized numeric solution engineered to deliver clear, reliable temperature readings for cooling/freezing compartments. Designed to thrive in refrigerated environments (typically -20°C to 10°C), this display features a 0.56" (14.2mm) character height for easy visibility through refrigerator doors, super bright yellow green illumination (569-573nm wavelength), and a common cathode configuration for seamless integration with refrigerator control boards.
With a space-efficient 37.6×19×8mm size, it fits into compact refrigerator control panels without compromising readability. The display’s low power consumption, even segment illumination, and RoHS/REACH compliance make it an eco-friendly, durable choice for home appliances. Multiple emitting color options (red, blue, green, etc.) further extend its versatility for other digital indicators like thermometers or humidity monitors.

Key Features
1. Refrigerator-Specific Reliability
Cold-Environment Stability: Engineered to operate flawlessly in refrigerator temperatures (-20°C to 10°C), avoiding display lag or failure common in generic displays exposed to cold.
Super Bright Yellow Green Illumination: 569-573nm wavelength and high luminous intensity cut through dim refrigerator interiors and frosted door panels, ensuring temperature readings (e.g., “2°C” for fridge, “-18°C” for freezer) are visible at a glance.
Triple Digit Layout: 3-digit design supports both positive (fridge) and negative (freezer) temperature ranges, eliminating the need for additional components to display minus signs.
2. Optimal Readability & Size
0.56" (14.2mm) Character Height: Balances readability (from across kitchens) and space efficiency (fits into slim refrigerator control panels). Digits are large enough to avoid eye strain but compact enough for modern appliance designs.
Even Segment Illumination: Luminance is uniformly distributed across each 7-segment digit, eliminating dim spots or “hot zones” that could obscure critical temperature information.
High Contrast: Yellow green light stands out against typical refrigerator interior colors (white, stainless steel), enhancing visibility without harsh glare.
3. Energy Efficiency & Durability
Low Power Consumption: Optimized forward voltage (1.8-2.4V/LED) and forward current (5-10mA/LED) minimize energy use—critical for appliances connected to continuous power, aligning with eco-friendly home standards.
Extremely Low Current: Reduces heat generation (preventing condensation issues in cold environments) and extends the display’s lifetime (typical 50,000+ hours), matching the 5-10 year lifespan of most refrigerators.
Long Operational Lifespan: High-quality LED chips and robust construction withstand daily on/off cycles and temperature fluctuations, ensuring consistent performance for years.
4. Easy Integration & Compliance
Common Cathode Configuration: Simplifies wiring with refrigerator control boards and standard driver ICs (e.g., TM1637, MAX7219), reducing circuit design complexity for appliance manufacturers.
Compact 37.6×19×8mm Size: Fits into tight spaces in refrigerator door panels or interior control clusters, avoiding costly modifications to appliance housing.
RoHS/REACH Compliant: Meets international environmental and safety standards, ensuring compatibility with global refrigerator markets (Europe, North America, Asia, etc.).

Applications
While optimized for refrigerators, this triple-digit LED display is also widely suitable for:
Home Appliances: Freezers, wine coolers, mini fridges, and air conditioners (for temperature readouts or mode indicators).
Digital Thermometers: Standalone or wall-mounted thermometers for home, office, or laboratory use (for indoor/outdoor temperature monitoring).
Humidity Indicators: Dehumidifiers, humidifiers, and weather stations (for humidity percentage readouts).
Process Indicators: Small industrial monitors or test equipment (for low-temperature or humidity-related data).
