0.56 Inch 7 Segment LED Display for Temperature Indicators
This 0.56-inch 7-segment LED display is engineered specifically for
temperature monitoring applications in thermostats, industrial
controllers, refrigeration units, and environmental sensors.
Designed for optimal readability, energy efficiency, and stable
performance across various environments, this display excels at
presenting critical temperature data with exceptional clarity.
Key Features
Precision Visibility for Temperature Data
- Targeted Wavelength & Brightness: 620-625nm red light provides high contrast against typical black
indicator surfaces, ensuring crisp digit and negative sign
visibility
- Even Luminous Distribution: Uniform segment brightness eliminates hot spots and dim edges that
could distort temperature values
- Multi-Color Options: Red (default), Green (optimal range cues), Blue (smart
thermostats), White, Amber, Orange, Yellow for brand customization
Industrial-Standard Design & Easy Integration
- Compact Industrial Size: Fits standard temperature indicator PCBs with 0.56-inch mounting
footprints
- Low Power Consumption: 5-10mA per LED extends battery life by up to 30% in portable
devices
- Broad Voltage Compatibility: 1.8-2.2V per LED matches standard temperature sensor power
supplies
Stable Performance Across Environments
- Temperature Resilience: Operates reliably from -10°C to 60°C with optional
high-temperature upgrades to 85°C
- Long Lifetime: 50,000+ hours matches the 8-10 year service life of most
temperature indicators
- Bright Ambient Light Resistance: Industrial-grade design prevents washout from sunlight or factory
lighting
Compliance & Versatility
- RoHS/REACH Compliant: Free from lead, mercury, and harmful substances for global market
compliance
- Multi-Scenario Compatibility: Works with humidity monitors, industrial process indicators, home
appliances, and audio equipment
- IC Compatibility: Seamlessly pairs with standard driver ICs and temperature sensors
