Ultra Bright White 12.7mm (0.5-Inch) 3-Digit (3½ Digit) 7-Segment
Common Cathode LED Display for Refrigerators
Product Overview
Introducing the Ultra Bright White 3-Digit (3½ Digit) 7-Segment
Common Cathode LED Display—a fridge-optimized numeric solution
engineered for refrigerator controllers, temperature/humidity
indicators, and home appliances. Designed to prioritize wide
temperature tolerance, clear readability, and durability, this
display excels at showing fridge-specific metrics: positive fridge
temperatures (e.g., “5°C”), sub-zero freezer temps (e.g., “-18°C”),
or humidity levels (e.g., “60% RH”).
Its 12.7mm (0.5-inch) character height ensures readability from 1–2
meters (typical kitchen distance for fridge checks), while the
38.2×19×8mm form factor fits slim fridge control panels—no bulky
redesigns required. The white segments on a black surface (with
film) boosts contrast with ultra bright white light, cutting
through kitchen glare (e.g., overhead lights, sunlight) without eye
strain.
With a wide operating temperature range (-35°C ~ +85°C), common
cathode polarity, and RoHS/REACH compliance, this display thrives
in fridge environments (from cold freezers to warm kitchens) and
delivers reliable performance for 24/7 use.

Key Features (Refrigerator-Optimized)
1. Wide Temperature Tolerance for Fridge Environments
Extreme Temp Range (-35°C ~ +85°C): Specifically designed to withstand fridge/freezer cold (-35°C for
deep freezers) and kitchen ambient heat (+85°C for warm
kitchens)—avoids segment dimming, frost damage, or performance loss
that plagues standard displays in extreme temps.
Freezer-Ready Design: No condensation buildup or component failure in sub-zero
conditions, ensuring consistent readability of freezer temps (e.g.,
“-20°C”) even after long-term use.
Protective Film: The film on the black surface shields segments from fridge
moisture, food splatters, and frequent wiping—easy to clean and
maintains clarity over the fridge’s 10–15 year lifespan.
2. 3½ Digit Functionality for Sub-Zero & Precision Readouts
Negative Value Support: As a 3½ digit display, it handles values from -199 to 999—critical
for showing sub-zero freezer temps (e.g., “-18°C”) without extra
wiring. Users instantly distinguish fridge (“5°C”) from freezer
(“-18°C”) without labels.
Precision for Fine Metrics: Supports decimal points for accurate temp/humidity readings (e.g.,
“4.5°C” for fridge, “55.5% RH” for humidity)—ideal for high-end
fridges with precise climate control.
3. Superior Visibility & Energy Efficiency
Ultra Bright White Illumination: High luminous intensity ensures temps are clear in bright kitchens
(e.g., morning sunlight) or dim rooms (e.g., nighttime fridge
checks)—no squinting to read “2°C” vs. “7°C”.
Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes fridge energy use (critical
for ENERGY STAR-certified models) and extends backup battery life
(for power outages, keeping temps visible).
White Segments on Black Surface: High contrast eliminates “washout” and makes digits/minus signs
sharp—avoids misreading “-8°C” as “8°C” (a costly mistake that
could spoil frozen food).
