High Visibility 0.39inch Blue 7 Segment LED Display Module

Core Technical Specifications

Key Features (Temperature Indicator-Optimized)
1. Temperature-Centric High-Contrast Visibility
Super Bright red Illumination: The 569-574nm light is eye-friendly and highly distinguishable in both bright indoor environments (living rooms, offices) and dim spaces. Perfect for displaying critical temperature thresholds.
White Segments + Black/Gray Face Contrast: Eliminates ambient light glare and ensures 3-digit temperature values are crisp and easy to read-even for users with mild visual impairment. No "washout" issues that plague low-contrast displays in sunlight or kitchen lighting.
Uniform Segment Luminance: Segments emit consistent brightness with no hot spots or dim edges, preventing misinterpretation of decimal temperature values in precision temperature control applications.
2. Energy Efficiency & Stable Performance
Low Power Consumption & Extremely Low Current: 12-15mA recommended forward current minimizes energy use for temperature controllers running 24/7, reducing household and commercial operational costs.
Stable Operation in Variable Temperatures: Withstands the ambient temperature fluctuations of its target applications and minor vibrations from appliance operation. No flickering or segment failure during long-term use.
Long Lifetime (50,000+ Hours): High-quality LED chips and robust epoxy construction match the 8-10 year service life of most home appliances and temperature controllers, eliminating frequent display replacements and maintenance downtime.
3. Manufacturer-Friendly Easy Integration
Common Cathode IC Compatibility: Works seamlessly with standard temperature controller driver ICs and microcontrollers. Simplifies circuit design for real-time temperature sampling, threshold alerts, and decimal point display functions.
Compact Industrial Size: The 37.6×19×8mm profile fits into narrow PCB layouts of air conditioner remote controls, refrigerator control panels, and portable temperature indicators-no custom PCB redesign required. Supports automated SMT production lines for high-volume manufacturing.
High Production Capacity: 20,000 pcs/day output ensures timely delivery for large-scale home appliance projects, while EXW trade terms offer flexible logistics options for global customers.
4. Multi-Color Versatility for Functional Differentiation
Optional emitting colors enable targeted use across diverse temperature control scenarios:
Red: High-visibility for over-temperature alarms
Amber: Warm tones for heating system temperature displays
Blue: Modern aesthetics for premium smart home temperature controllers
