Pure Green 0.56-Inch 4-Digit 7-Segment Common Cathode LED Display for Instrument Panels
Product Overview
Introducing the Pure Green 0.56-Inch 4-Digit 7-Segment Common Cathode LED Display—a high-performance numeric solution engineered exclusively for instrument panels, where precision, visibility, and reliability are critical. Designed to deliver clear readouts of metrics like voltage, pressure, or temperature (e.g., "24.5V," "100°C"), this display combines a 0.56-inch (14.2mm) character height for easy reading, pure green illumination (515-525nm wavelength), and a robust common cathode design to thrive in industrial and household instrument environments.
With a slim 50.3×19.0×8mm form factor, white segments on a black surface (enhancing contrast), and 10mm long pin leads for secure PCB mounting, it integrates seamlessly into dense instrument panels without compromising space. Its high luminous intensity (140-160mcd), low power consumption, and RoHS compliance make it ideal for 24/7 instrument operation—while multiple color options adapt to diverse design and functional needs.

Key Features
1. Instrument Panel-Optimized Design
4-Digit Layout: Supports extended numeric ranges (0000–9999) and decimal values, perfect for instrument metrics like "123.4" (pressure) or "-050" (sub-zero temperature)—eliminating the need for multiple smaller displays.
0.56-Inch (14.2mm) Character Height: Balances readability (from 1–2 meters, typical instrument viewing distance) and space efficiency—digits are large enough to avoid eye strain but compact enough for dense panel layouts (e.g., alongside buttons or sensors).
White Segments on Black Surface: Creates sharp contrast with pure green light, ensuring metrics stand out against cluttered instrument panels—critical for quick, accurate readings in high-pressure industrial settings.
2. Superior Visibility & Performance
Pure Green Illumination: 515-525nm wavelength and 140-160mcd luminous intensity cut through ambient light (e.g., factory floor lighting, lab overheads), ensuring readability even in bright conditions. Pure green is also gentle on the eyes for prolonged monitoring.
Stable Operation: Engineered to withstand voltage fluctuations (common in industrial power supplies) and temperature variations (0°C–50°C, typical instrument range), maintaining consistent brightness and segment clarity—no flickering or dimming during critical measurements.
Extremely Low Current: 10-15mA per LED and 2.8-3.3V forward voltage minimize power consumption, ideal for battery-powered portable instruments or energy-efficient fixed panels.
3. Easy Integration & Durability
Common Cathode Polarity: Compatible with standard instrument driver ICs (e.g., TM1637, MAX7219), simplifying circuit design for engineers and ensuring seamless integration with existing instrument firmware.
10mm Long Pin Leads: Provides secure, easy mounting on instrument PCBs—reduces the risk of loose connections in vibration-prone environments (e.g., industrial machinery panels).
Long Lifespan: High-quality LED chips ensure a typical lifespan of 50,000+ hours—matching the 5–10 year service life of most instruments, minimizing maintenance and replacement costs.
4. Flexibility & Compliance
Multi-Color Options: Beyond pure green, choose from red (alerts), blue (branding), yellow green, amber, orange, or pure white to align with functional cues (e.g., red for "high pressure," green for "normal range").
RoHS Compliant: Meets international environmental and safety standards, ensuring compatibility with global instrument markets (Europe, North America, Asia)—no regulatory barriers for export.
Easy-to-Assemble: Designed for hassle-free PCB insertion, supporting automated production lines for high-volume instrument manufacturing.
