उत्पाद का वर्णन
Custom Design Triple Digit 7 Segment LED Display with Minus Sign Common Anode for Refrigerator
Introducing the Custom Design 3-Digit (3½ Digit) 7-Segment LED Display with Minus Sign--a fridge-optimized numeric solution engineered for refrigerator controllers, temperature indicators, and home appliances requiring negative value readouts.

Key Features (Refrigerator-Optimized)
1. 3½ Digit + Minus Sign for Sub-Zero Temps
  • Negative Value Support: Dedicated minus sign enables clear display of freezer temperatures (e.g., "-18°C", "-20°C")--critical for fridge-freezer combos where distinguishing positive/negative values prevents food spoilage.
  • 3½ Digit Range: Covers -199 to 999, fitting all typical fridge/freezer temp needs (fridge: 0-10°C, freezer: -10--25°C) and leaving room for humidity or timer values.
  • Protective Film: Shields segments from moisture, food splatters, and frequent wiping, maintaining clarity and preventing scratches over time.
2. Multicolor Functionality for Fridge-Specific Cues
  • Ultra Bright White: Ideal for standard fridge temps (e.g., "5°C")--neutral, eye-friendly for daily checks.
  • Red: Signals freezer temps (e.g., "-18°C") or alerts (e.g., "-25°C" too cold, "OPEN" door-left-open)--grabs attention for critical info.
  • Pure Green: Use for secondary metrics (e.g., "50%" fridge humidity, "DEF" defrost mode)--clearly distinguishes from primary temp values.
3. Superior Visibility & Energy Efficiency
  • High Luminous Intensity: Bright enough to cut through kitchen glare but not harsh in dim kitchens--ensures temps are readable day/night.
  • Low Power Consumption: Extremely low current draw (5-10mA/LED) minimizes fridge energy use--critical for ENERGY STAR-certified models.
  • White Segments on Black Surface: High contrast eliminates "washout" and makes digits/minus signs sharp.
4. Reliable Performance & Easy Integration
  • Stable Operation in Fridge Environments: Withstands temperature fluctuations (-10°C to 50°C) and minor vibrations (door slamming, compressor cycles).
  • Long Lifespan (50,000+ Hours): High-quality LEDs match the 10-15 year service life of most fridges.
  • Common Anode Polarity: Works with standard fridge driver ICs (e.g., TM1637, HT1621)--simplifies circuit design.
  • Easy Assembly: Designed for PCB mounting, compatible with automated production lines.

Applications
While optimized for refrigerator controllers, this display also excels in:
  • Temperature Indicators: Freezer monitors (e.g., "-20°C"), cold storage sensors (e.g., "-5°C"), or heat pump controllers (e.g., "-3°C" defrost).
  • Home Appliances: Smart thermostats (e.g., "-2°C" outdoor temp), wine coolers (e.g., "12°C"), or mini fridges (e.g., "8°C").
  • Instrument Panels: HVAC control panels (e.g., "22°C" room temp, "-10°C" outdoor), or laboratory cold chamber monitors (e.g., "-80°C" ultra-low temp).

Why Choose This Custom Display for Refrigerators?
  • Minus Sign for Freezers: Eliminates temp ambiguity--critical for preventing freezer food spoilage or fridge overcooling.
  • Fridge-Sized Fit: Slim dimensions fit standard fridge control panels--no need to resize existing designs.
  • Intuitive Multicolor Cues: White for fridge, red for freezer--users instantly recognize temps without reading labels.
  • Energy & Cost Savings: Low power use cuts fridge energy bills; long lifespan reduces replacement costs.
  • Global Compliance: RoHS/REACH certification ensures export to international markets, meeting fridge safety standards.
