Product Introduction

Adopting high-purity LED chips and food-grade ABS shell material (safe for kitchen environments), the 3-digit digital screen features a working voltage of DC 3V-5V, perfectly matching the low-power requirements of home appliances. Its optimized optical design ensures that 3-digit numbers (000-999) are displayed clearly, with a viewing distance of up to 5 meters and no color distortion. Measuring only 35mm×18mm×6mm, it fits seamlessly into the compact interiors of various home appliances, providing users with instant access to key information such as temperature, time, and operating status.

Whether installed on refrigerators, microwaves, or water heaters, this digital screen maintains stable performance in humid, high-temperature, and oil-fume environments, adhering to international safety standards such as UL, CE, and RoHS. It is the preferred display solution for home appliance manufacturers focusing on user experience and product quality.

Product Advantages

Ultra-Clear Visibility for Home Scenarios: Equipped with anti-glare matte coating and 300-500 cd/m² adjustable brightness, the screen remains readable even under strong kitchen lights or direct sunlight through windows. The large, bold 3-digit font design caters to users of all ages, including the elderly.

Home-Environment Durability: With IP65 waterproof and oil-proof rating, it resists oil fumes from stoves, steam from dishwashers, and water splashes from washing machines. The high-temperature resistance (up to 100℃ short-term) adapts to the heat generated by appliances like ovens and toasters.

Extreme Energy Efficiency: Power consumption is as low as 0.5W, which is 60% lower than traditional LCD displays. When paired with home appliances, it barely affects overall energy consumption, aligning with the global trend of energy-saving home products.

Strong Compatibility with Appliance Systems: Supports TTL and I2C communication protocols, easily integrating with the control systems of refrigerators, air conditioners, water heaters, and other home appliances. The plug-and-play interface reduces the R&D cycle for appliance manufacturers.

Long-Lasting & Low Maintenance: The LED chips have a service life of over 50,000 hours (equivalent to 17 years of daily use for 8 hours), and the shell is scratch-resistant and fade-proof. No regular maintenance is required, reducing after-sales costs for manufacturers.

Product Features

- Wide Viewing Angle Design: 160° horizontal and 140° vertical viewing angles ensure that users can read the display clearly from any position in the kitchen or living room, avoiding the need to lean close to the appliance.

- Soft Light & Eye Protection: 100Hz refresh rate and warm white light (3000K-4000K) prevent screen flicker and glare, protecting users' eyesight, especially when using appliances at night (e.g., microwave ovens in the evening).

- Multiple Display Modes: Supports numerical display (temperature, time, power), symbol prompt (heating, cooling, standby), and brightness auto-adjustment (dims automatically at night to avoid disturbing rest).

- Quick Response & Stable Performance: Response time less than 1ms, ensuring that the display updates instantly when adjusting appliance settings (e.g., changing the temperature of an air conditioner).

- Easy Installation & Replacement: Compact size and snap-in installation structure allow it to be installed in narrow spaces of appliances. The standardized interface makes replacement simple for after-sales maintenance.

- Safety-Certified Structure: Insulation resistance ≥100MΩ, preventing electric leakage risks. The flame-retardant shell meets V-0 level fire safety standards, ensuring home use safety.

Application Fields

Kitchen Appliances: Ideal for microwaves, ovens, induction cookers, and rice cookers. Displays cooking time, temperature settings, and working status (e.g., "05:00" for 5 minutes of heating, "180℃" for baking temperature). The oil-proof and high-temperature resistance design adapts to the kitchen environment.

Bathroom Appliances: Used in electric water heaters, smart toilets, and bathroom heaters. Shows water temperature (e.g., "45℃"), heating status, and remaining hot water volume. The waterproof performance prevents damage from steam and water splashes.

Climate Control Appliances: Embedded in air conditioners, dehumidifiers, and heaters. Displays room temperature, set temperature, and operating mode (cooling/heating). The wide viewing angle allows users to read data from the sofa or bed.

Storage Appliances: Installed on refrigerators and freezers. Shows internal temperature (e.g., "-18℃" for freezer, "5℃" for refrigerator) and energy-saving mode status. The low-power design aligns with the energy efficiency requirements of refrigerators.

Laundry Appliances: Applied to washing machines and dryers. Displays remaining working time, water level, and washing mode (e.g., "20min" remaining, "ECO" mode). The anti-corrosion shell resists detergent residues.

Small Smart Appliances: Suitable for electric kettles, coffee machines, and air purifiers. Shows water temperature, brewing time, and air quality index. The compact size fits the small structure of these appliances.

Product FAQ

Q1: Can this 3-digit digital screen be used in high-humidity environments like bathrooms?

A1: Yes. It has IP65 waterproof rating, which can effectively resist steam, water splashes, and humidity in bathrooms. Many electric water heater manufacturers have adopted this product for bathroom scenarios, and it has passed 1000-hour humidity resistance tests.

Q2: Is the brightness of the screen adjustable to avoid disturbing sleep at night?

A2: Absolutely. The screen supports two brightness modes (high/low) and can be linked with the appliance's night mode. When the appliance enters night mode, the screen automatically dims to 50% brightness, which is soft and not dazzling, perfect for bedrooms or kitchens adjacent to living rooms.

Q3: What is the compatibility with different home appliance control systems?

A3: It supports mainstream TTL and I2C communication protocols, which are widely used in home appliance control systems. We provide detailed wiring diagrams and sample codes, and our technical team can assist with protocol adaptation for non-standard systems to ensure smooth integration.

Q4: How to solve the problem of screen dimming after long-term use?

A4: Our digital screen uses high-stability LED chips, and the brightness attenuation is less than 10% after 50,000 hours of use. If abnormal dimming occurs, it is usually caused by poor power contact. Check the power line connection or replace the power supply module to restore normal use.

Q5: Can the display color and font size be customized according to appliance design needs?

A5: Yes. We offer customization services for display color (red, blue, green, white, etc.), font size (12mm-20mm), and even screen shape (square, rounded). The minimum order quantity for customized products is 300 pieces, and the sample can be provided within 3 working days.

Q6: What certifications does this product have, and is it suitable for export to European and American markets?

A6: The product has obtained UL, CE, RoHS, and FCC certifications, fully complying with the safety and environmental protection standards of European and American markets. It has been widely used by home appliance brands exported to the United States, Germany, France, and other countries.
