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, freezer temperature, or defrost cycle countdowns.
The display's 0.67-inch (17.12mm) character height ensures readability from across kitchens, 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 and yellow for alerts—help users instantly recognize fridge status. Paired with white segments on a black surface 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: Default for normal temperatures – calm, easy on the eyes for daily checks. Yellow: Alerts for abnormal conditions – grabs attention without being harsh. Auto-switching capability: Toggles color based on temperature thresholds. |
| Scratch-Resistant Film | Custom-thickened film (150μm) withstands frequent fridge door openings/closing, spills, and wipe-downs– 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 but not so bright to be distracting at night. |

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 ensure it lasts as long as the appliance.
Kitchen-Friendly Visibility: Tuned luminous intensity works in bright daylight and dim evenings.
Easy Fridge Integration: Common anode polarity matches fridge control board ICs , 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
While optimized for fridge control panels, this display also excels in other home appliances and HVAC systems:
Air Conditioner Controls: White for "24°C" + yellow for "30°C".
Freezer Standalones: White for "-18°C" + yellow for "-25°C".
Heating Systems: White for "22°C" + yellow for "28°C".
