0.56 Inch 7 Segment LED Display for Temperature Indicators
Product Description
Introducing the 0.56-Inch 7-Segment LED Display-a temperature monitoring-optimized solution engineered for thermostats, industrial temp controllers, refrigeration units, and environmental sensors. Designed to prioritize clear temperature readability, energy efficiency, and stable performance across environments, this display excels at showing critical temperature data: room temp , industrial process temp, sub-zero freezer temp, or humidity-correlated temp.
Its 0.56-inch character height ensures readability from 0.5-3 meters, while the industrial-standard size fits seamlessly into compact temperature indicator enclosures-no bulky redesigns required. The targeted wavelength and 80-100mcd luminous intensity cut through ambient glare without eye strain, ensuring quick recognition of temperature fluctuations.
With low power consumption, uniform segment brightness, and RoHS/REACH compliance, this display combines durability, energy efficiency, and global usability-ideal for 24/7 operation in temperature monitoring devices.
Key Features (Temperature Indicator-Optimized)
1. Precision Visibility for Temperature Data
Targeted Wavelength & Brightness: 620-625nm red light (default) offers high contrast with temperature indicators' typical black surfaces, ensuring digits and negative signs are crisp. 80-100mcd luminous intensity balances visibility (clear in bright ambient light) and eye comfort.
Even Luminous Distribution: Segments emit uniform brightness - no "hot spots" or dim edges that distort critical temperature values or negative signs.
Multi-Color Temperature-Centric Options:
Red: Default for temp readouts (high visibility, universal recognition for critical data).
Green: Ideal for "optimal temp range" cues.
Blue: Modern aesthetics for smart thermostats.
White/Amber/Orange/Yellow: Customizable for brand-specific designs or functional differentiation.
2. Industrial-Standard Design & Easy Integration
Compact Industrial Size: Engineered to fit standard temperature indicator PCBs (compatible with 0.56-inch 7-segment mounting footprints), enabling seamless integration into existing device designs. Supports single-digit to 4-digit configurations (customizable digit count) for diverse temp ranges.
Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes energy use for battery-powered temp indicators and 24/7-run controllers, extending battery life by up to 30% compared to standard displays.
Broad Voltage Compatibility (1.8-2.2V/LED): Matches standard temperature sensor power supplies, ensuring stable brightness without voltage regulation issues-simplifies circuit design for engineers.
3. Stable Performance Across Environments
Temperature Resilience: Operates reliably in -10°C to 60°C, with optional high-temperature upgrades (up to 85°C) for industrial process monitoring. Withstands thermal shock without flickering or segment failure.
Long Lifetime (50,000+ Hours): High-quality LED chips and durable epoxy construction match the 8-10 year service life of most temperature indicators-eliminating frequent replacements and reducing maintenance hassle for users.
Bright Ambient Light Resistance: Industrial-grade segment design prevents "washout" from sunlight or factory overhead lights, ensuring consistent readability in all conditions.
4. Compliance & Versatility
RoHS/REACH Compliant: Free from lead, mercury, and harmful substances-safe for indoor use and export to global markets (EU, North America, Asia), meeting strict environmental and consumer safety standards.
Multi-Scenario Compatibility: Beyond temperature indicators, works for humidity monitors, industrial process indicators, home appliances (microwaves, refrigerators), and audio equipment-reducing the need for multiple display types in product lineups.
IC Compatibility: Seamlessly pairs with standard driver ICs and temperature sensors-enabling real-time temp data sync and display without additional adapters.
