Core Product Features
1. Dual Polarity: Universal Circuit Compatibility
Eliminates the need to source separate CC/CA models—works seamlessly with both common cathode and common anode circuits. This simplifies inventory management for manufacturers producing mixed product lines, reducing development costs and production delays.
2. High-Contrast Design & Uniform Illumination
White Segments on Black Surface: Minimizes glare and maximizes digit sharpness, ensuring clear readability in bright kitchens or dim bedrooms.
Even Luminous Distribution: Light spreads consistently across all 7 segments, avoiding "hotspots" or dark spots—critical for accurate readings of timer values or set-top box channel numbers.
3. Energy Efficiency for Long-Term Use
Low Power Consumption & Extremely Low Current: Reduces energy usage, making it ideal for 24/7 operated devices or battery-powered digital timers.
Durable Performance: Stable operation and RoHS compliance ensure safety and longevity, even in high-use scenarios.
4. Multi-Color Flexibility
7 emission colors cater to diverse application needs:
Red/Amber: Ideal for alerts or high-visibility displays
Green/White: Suited for "normal status" readouts or clock displays.
Blue/Yellow/Orange: Perfect for brand-specific aesthetics
