Product Introduction

As a professional manufacturer specializing in LED digital tubes, LED color screens, and LED single/double color strips for over 15 years, we proudly present our Multi-Color Display Home appliance digital screen—an innovative display solution designed to elevate the user experience of modern smart home appliances. This product transcends the functional limitations of traditional monochrome displays, integrating vivid RGB color expression with industrial-grade reliability to deliver intuitive, visually engaging information feedback for household electronics.

Crafted with premium Epistar RGB LED chips and medical-grade PC shell material, this digital screen operates at a low DC 3V-5V voltage, aligning with the energy-saving requirements of contemporary home appliances. It supports both 3-digit numerical display (covering 000-999 for temperature, time, and power data) and 256-level color gradient, enabling dynamic color-coded prompts that simplify user interaction. With a ultra-compact dimension of 32mm×16mm×5mm, it seamlessly fits into the tight internal spaces of various appliances, from compact coffee machines to large-capacity refrigerators.

Engineered to withstand the harsh conditions of home environments—including kitchen oil fumes, bathroom steam, and temperature fluctuations—this multi-color digital screen holds UL, CE, RoHS, and FCC certifications. It has become a favored component for home appliance brands targeting global markets, ensuring consistent performance and user satisfaction across regions.

Product Advantages

Intuitive Color-Coded Interaction: Features 16.7 million true colors with a CRI of 92+, enabling clear color differentiation for appliance states—such as green for normal operation, blue for standby, yellow for warm-up, and red for faults. This intuitive design reduces operational learning costs, making it user-friendly for all age groups, especially the elderly and children.

Home-Environment Resilience: Boasts IP66 waterproof and oil-proof ratings, effectively repelling kitchen grease, bathroom moisture, and detergent residues. It tolerates a wide temperature range of -20℃ to 100℃, ensuring stable display on appliances like ovens (with heat insulation) and freezers.

Ultra-Efficient Energy Saving: Consumes only 0.5W in full-color mode and 0.1W in standby, 60% lower than traditional multi-color displays. When integrated into smart appliances, it contributes to meeting global energy efficiency standards, enhancing product market competitiveness.

Broad Compatibility & Easy Integration: Supports TTL, I2C, and SPI communication protocols, matching control systems of 95% of home appliances. Standardized pinouts and plug-and-play design reduce R&D and assembly time for manufacturers, accelerating product launch cycles.

Long-Term Reliability: LED chips offer a service life of over 70,000 hours (equivalent to 25 years of 8-hour daily use), with brightness attenuation less than 8% after long-term operation. The scratch-resistant and fade-proof shell ensures no maintenance is required during the appliance's lifecycle.

Product Features

- Wide Anti-Glare Viewing Angle: 175° horizontal and 160° vertical viewing angles, paired with an anti-glare matte coating, ensure clear visibility from any corner of the room—even under direct kitchen lights or sunlight.

- Smart Eye-Protective Design: 120Hz high refresh rate eliminates flicker, while auto-dimming technology adjusts brightness based on ambient light (e.g., dimming to 30% at night). The 3000K-6500K adjustable color temperature adapts to day and night use.

- Dynamic Display Modes: Supports numerical display (temperature, time), color gradients (power level), flashing prompts (fault alerts), and symbol indicators (heating/cooling). Customizable display logic caters to specific appliance functions.

- Instant Response Performance: Response time of less than 0.3ms ensures real-time display updates when adjusting appliance settings—such as modifying air conditioner temperature or microwave cooking time—without lag.

- Flexible Installation Options: Offers snap-in, screw-mounted, and adhesive installation methods to fit different appliance structures. The compact size allows installation in narrow spaces like appliance control panels.

- Enhanced Safety Features: Insulation resistance ≥200MΩ prevents electric leakage, while the V-0 grade flame-retardant shell and overload protection circuit eliminate fire risks, ensuring home use safety.

Application Fields

Kitchen Appliances: Perfect for microwaves, induction cookers, rice cookers, and air fryers. Displays cooking time (green countdown), temperature (red for high heat), and working mode (blue for defrost). Oil-proof and high-temperature resistant design stands up to kitchen conditions.

Bathroom Appliances: Ideal for electric water heaters, smart toilets, and towel warmers. Shows water temperature (green for 38-45℃, red for >50℃), heating status, and water level. IP66 waterproof rating resists steam and splashes, with anti-fog technology ensuring clear display.

Climate Control Appliances: Embedded in air conditioners, dehumidifiers, and space heaters. Displays room temperature, set temperature, and mode (blue for cooling, red for heating, green for auto). Wide viewing angle allows easy reading from sofas or beds.

Storage Appliances: Used in smart refrigerators and freezers. Shows internal temperature (blue for freezer, green for fridge), freshness reminder (yellow for food storage alerts), and energy-saving mode status. Low-power design aligns with fridge energy standards.

Laundry Appliances: Applied to washing machines and dryers. Displays remaining time, water level, and washing mode (green for eco-wash, red for quick-wash). Anti-corrosion shell resists detergent residues and humidity.

Product FAQ

Q1: Will the multi-color display fade in the high-temperature environment of a kitchen?

A1: No. The product uses high-temperature resistant LED chips and heat-insulating shell material, which can withstand short-term high temperatures up to 100℃. It has passed 3000-hour high-temperature tests without color fading or display distortion, making it fully suitable for kitchen appliances like ovens and induction cookers.

Q2: Can the color logic be customized to match our brand's visual identity?

A2: Absolutely. We offer fully customizable color logic—for example, using your brand's signature color for normal operation or setting unique color combinations for specific functions. Our R&D team will provide sample programs and test samples to ensure the display aligns with your brand image before mass production.

Q3: Is this digital screen compatible with battery-powered small home appliances?

A3: Yes. With ultra-low power consumption (0.5W in full-color mode, 0.1W in standby), it is perfectly compatible with battery-powered appliances like portable electric kettles and mini humidifiers. We also offer a low-power version that consumes only 0.3W, further extending battery life.

Q4: What should I do if the display shows garbled characters or abnormal colors?

A4: Garbled characters or abnormal colors are usually caused by signal line misconnection or protocol mismatch.
