Super Bright Orange 10.16mm (0.4-Inch) 4-Digit 7-Segment Common Cathode LED Display for Home Appliances
Product Overview
Introducing the Super Bright Orange 0.4-Inch 4-Digit 7-Segment Common Cathode LED Display—a warm-toned, high-visibility solution engineered for home appliances, set-top boxes, and digital indicators. Designed to balance cozy aesthetics (via orange light), clear readability, and energy efficiency, this 4-digit display excels at showing appliance-specific metrics: microwave cook time (e.g., "05:00"), set-top box channel (e.g., "120"), or instrument panel values (e.g., "25°C" for temperature).
Its 10.16mm (0.4-inch) character height ensures readability from 0.5–2 meters (typical distance for kitchen or living room appliance checks), while the 40.5×16×7mm form factor fits into slim appliance control panels—no bulky redesigns required. The white segments on a black surface create sharp contrast with super bright orange light (600-605nm), cutting through ambient glare (e.g., kitchen lights, living room lamps) without eye strain, and adding a welcoming touch to home environments.
With common cathode polarity, low power consumption, and RoHS compliance, this display combines durability, eco-friendliness, and home-friendly design—ideal for 24/7 operation in daily-use home appliances.

Key Features (Home Appliance-Optimized)
1. Warm Orange Light for Home-Friendly Aesthetics & Visibility
Super Bright Orange Illumination (80-100mcd, 600-605nm): Orange light delivers a cozy, non-harsh glow—perfect for home environments (e.g., kitchen microwaves, bedroom set-top boxes) where harsh white/blue light might feel jarring. It stands out in bright kitchens (e.g., sunlight through windows) and remains gentle on eyes during evening use (e.g., late-night TV channel checks).
White Segments on Black Surface: High contrast eliminates "washout" and ensures digits (0-9) and symbols (e.g., colon for time "01:45") stay sharp—no misreading "08:00" as "03:00" (a mistake that could overcook food or miss a show).
Even Luminous Distribution: Light spreads uniformly across each segment (no "hot spots" or dim edges), so every bar of digits (e.g., the bottom bar of "6") is consistent—guarantees accurate value recognition at a glance.
2. Compact Design & Easy Integration
Slim Dimensions (40.5×16×7mm): Fits into dense appliance PCBs (e.g., microwaves with timer + temp displays) or slim enclosures (e.g., flat-set top boxes)—no need to enlarge appliance designs for 4-digit readouts.
Common Cathode Polarity: Works with standard home appliance driver ICs (e.g., TM1637, HT1621, MAX7219)—simplifies circuit design for manufacturers and integrates seamlessly with appliance firmware (e.g., timer counting, channel switching).
Easy Assembly: Designed for PCB direct-mounting, compatible with automated production lines—speeds up manufacturing for high-volume appliances (e.g., 10,000+ microwaves) and ensures consistent alignment in control panels, reducing installation errors.
3. Energy Efficiency & Stable Performance
Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes energy use—cuts electricity costs for 24/7-run appliances (e.g., set-top boxes) and avoids draining power from smaller devices (e.g., portable mini-fridges).
Optimized Forward Voltage (1.8-2.2V): Lower voltage than blue/green displays reduces power waste while maintaining brightness—aligns with eco-friendly home appliance trends (e.g., ENERGY STAR-certified microwaves).
Stable Operation in Home Environments: Withstands temperature fluctuations (-10°C to 50°C, typical for kitchens/living rooms) and minor vibrations (e.g., closing microwave doors, moving set-top boxes)—maintains consistent brightness, no flickering during value updates (e.g., timer countdowns).
Long Lifespan (50,000+ Hours): High-quality orange LED chips match the 8–10 year service life of most home appliances—eliminates frequent display replacements, reducing maintenance hassle for users.
4. Versatility & Compliance
Multi-Color Options: Beyond super bright orange, available in red (for alerts), blue (modern aesthetics), green (eco-cues), amber, white, and more—flexible for functional cues (e.g., red for "error" in microwaves, green for "standby" in set-top boxes) or brand-specific appliance designs.
RoHS Compliant: Free from lead, mercury, and harmful substances—safe for family use (even around children's bedrooms) and export to global markets (EU, North America, Asia), meeting home appliance safety standards.
