Customized white / yellow Triple Digit LED Display for refrigerator control panel
Product Overview
Introducing the Customized White/Yellow 3-Digit 7-Segment Common Anode LED Display—a fridge-optimized numeric solution engineered to deliver clear, functional temperature readouts for refrigerator/freezer control panels. Tailored for household refrigeration systems, its 3-digit layout perfectly accommodates core metrics: fridge temperature (e.g., "5°C"), freezer temperature (e.g., "-18°C"), or defrost cycle countdowns (e.g., "10min").
The display's 0.67-inch (17.12mm) character height ensures readability from across kitchens (no bending to check temps), while the slim 37.9×20.45×5.75mm form factor fits seamlessly into compact fridge control clusters. Key customizations—white illumination for "normal" temperature ranges (e.g., 2°C–8°C for fridges) and yellow for alerts (e.g., "-25°C" for over-cooling)—help users instantly recognize fridge status. Paired with white segments on a black surface (protected by a scratch-resistant film) and common anode polarity, it balances durability, usability, and easy integration—all while meeting RoHS standards for eco-friendly home use.

Core Customizations for Refrigerator Control
This display is tailored to solve fridge-specific usability and design needs, with a focus on white/yellow dual-color functionality:
| Customization FeatureDetails | Fridge-Specific Benefits |
| Dual-Color Illumination (White/Yellow) | White: Default for normal temperatures (e.g., "5°C" fridge, "-18°C" freezer) – calm, easy on the eyes for daily checks.- Yellow: Alerts for abnormal conditions (e.g., "-25°C" over-cooling, "10°C" fridge warming) – grabs attention without being harsh.- Auto-switching capability: Toggles color based on temperature thresholds (programmed via fridge control board). |
| Scratch-Resistant Film (Black Surface) | Custom-thickened film (150μm) withstands frequent fridge door openings/closing, spills, and wipe-downs (compatible with kitchen cleaners) – maintains clarity for the fridge's 8–10 year lifespan. |
| Fridge-Optimized Luminous Intensity | Tuned to 110–130mcd/LED – bright enough to cut through kitchen ambient light (e.g., overhead lamps) but not so bright to be distracting at night (critical for fridges in open-concept kitchens). |
| Package Dimenions | 37.9 x 20.45 x 5.75 mm |
| Character Height | 0.67-inch |
| Polarity | Common anode |
| Face Colour | Yellow Segments Black Face with Film |
| Emitting Colour | White / yellow |
| Application | Refrigerator Control |
| Category | Parameter | Specification (Refrigerator-Optimized) |
| Basic Design | Display Type | 3-Digit 7-Segment LED Numeric Display |
| Polarity | Common Anode (compatible with fridge control board ICs like TM1637) | |
| Character Height | 0.67 inches (17.12mm) – readable from 1–3 meters (kitchen distance) | |
| Outer Dimensions (L×W×H) | 37.9 × 20.45 × 5.75mm – fits standard fridge control panel cutouts | |
| Segment/Surface Finish | White segments on Black Surface + 150μm scratch-resistant protective film | |
| Optical Performance | Emitting Colors | Primary: White/yellow (dual-color, auto-switching); Optional: Red/blue/green/amber/orange |
| Luminous Intensity | 110–130mcd/LED (optimized for kitchen lighting) | |
| Color Switching Trigger | Programmable via fridge control board (e.g., < -20°C = yellow, 2°C–8°C = white) | |
| Electrical Parameters | Power Consumption | Low (3.2–3.6V, 10–12mA/LED) – compatible with fridge low-voltage power supplies |
| Quality & Compliance | Core Advantages | High reliability (withstands fridge temperature cycles), long lifespan (50,000+ hours), easy assembly |
| Certificate | RoHS Certified (free from lead/mercury – safe for home use) |

Why This Custom Display Is Ideal for Refrigerators
Alert-Driven Dual-Color Design: White/yellow auto-switching eliminates guesswork – users instantly know if the fridge is too warm/cold, reducing food spoilage risk.
Fridge-Sized Durability: Thickened scratch-resistant film and stable performance in fridge temperature cycles (-10°C–40°C) ensure it lasts as long as the appliance.
Kitchen-Friendly Visibility: Tuned luminous intensity works in bright daylight (kitchen windows) and dim evenings (no harsh glow when grabbing midnight snacks).
Easy Fridge Integration: Common anode polarity matches fridge control board ICs (e.g., TM1637), so manufacturers don't need to redesign circuits.
Eco-Friendly Home Use: RoHS compliance ensures it's safe for families, aligning with modern "green home" trends.
Additional Applications (Beyond Refrigerators)
While optimized for fridge control panels, this display also excels in other home appliances and HVAC systems:
Air Conditioner Controls: White for "24°C" (normal) + yellow for "30°C" (overheating alert).
Freezer Standalones: White for "-18°C" + yellow for "-25°C" (over-cooling).
Heating Systems: White for "22°C" (room temp) + yellow for "28°C" (overheating).
