WIFI-Controlled Ultra Bright Red 4-Digit 7-Segment Common Cathode LED Display for Digital Microwaves
Product Overview
Introducing the WIFI-Controlled Ultra Bright Red 4-Digit 7-Segment Common Cathode LED Display—a high-performance, smart-ready numeric solution engineered exclusively for WIFI-enabled digital microwaves. Designed to integrate seamlessly with modern microwave WIFI control systems, this display delivers clear, reliable readouts for cooking times, power levels, and WIFI-connected statuses (e.g., "REMOTE" for app-controlled operation) while withstanding the high-heat environment of microwave interiors (+105°C to +120°C).
With a 0.49inch character height for easy kitchen visibility, ultra bright red illumination (cutting through microwave door tint and kitchen glare), and a compact 61×43×20mm package, it fits into standard microwave control panels. The common cathode configuration and SMD pin type simplify integration with WIFI-enabled microwave PCBs, while low power consumption, long lifetime, and RoHS/REACH compliance ensure eco-friendly, durable performance. Multiple LED color options further adapt to brand-specific microwave designs.

Key Features
1. WIFI-Ready for Smart Microwaves
Seamless WIFI Control Integration: Compatible with microwave WIFI modules and smart control systems (e.g., app-based cooking timers, remote temperature adjustments), displaying real-time WIFI-connected statuses (e.g., "APP" for app control, "SYNC" for timer synchronization) alongside cooking data.
SMD Pin Type: Surface-mount design enables secure, space-efficient mounting on WIFI-enabled microwave PCBs, supporting automated assembly lines for high-volume smart appliance production.
IC Compatibility: Works with standard driver ICs used in smart microwaves (e.g., TM1638 for multi-function displays), reducing circuit design complexity for WIFI control integration.
2. Microwave-Grade Heat Resistance
High-Temperature Operation: Withstands +105°C to +120°C—critical for microwave interiors, where heat from cooking can damage standard displays. Ensures no flickering, dimming, or failure during prolonged microwave use.
Robust Construction: Engineered to resist minor vibrations and temperature fluctuations, maintaining stable performance even in frequent-use kitchen environments.
3. Superior Visibility & User Experience
Ultra Bright Red Illumination: High luminous intensity cuts through microwave door tint, kitchen overhead lights, and sunlight, ensuring cooking times or WIFI statuses are readable at a glance.
0.49inch Character Height: Balances readability and panel space efficiency—ideal for smart microwaves where control panels must accommodate WIFI buttons and display.
Big Viewing Angle: Wide horizontal/vertical visibility ensures the display is readable from multiple kitchen positions, enhancing user convenience.
4. Energy Efficiency & Compliance
Low Power Consumption: Optimized for minimal energy use, aligning with smart appliance energy efficiency standards and reducing power draw from microwave WIFI modules.
Long Lifetime: High-quality LED chips ensure a typical lifespan of 50,000+ hours—matching the 5-10 year service life of smart microwaves, minimizing replacement needs for end-users.
RoHS/REACH Compliant: Meets international environmental and safety standards, ensuring compatibility with global smart microwave markets (Europe, North America, Asia, etc.).
