Pure Green Common Cathode 0.56-Inch Triple-Digit 7-Segment LED Display for Instrument Panels

Product Overview

Introducing the Pure Green Common Cathode 0.56-Inch Triple-Digit 7-Segment LED Display—a high-visibility, industrial-grade numeric solution engineered exclusively for instrument panels, air conditioner controllers, and precision monitoring devices. Designed to prioritize clarity and reliability, this display features a 0.56-inch (14.2mm) character height for easy readability of critical metrics (e.g., "25°C," "60% RH"), pure green illumination (512-515nm wavelength), and a common cathode configuration for seamless integration with instrument control boards.

With a space-efficient 37.6×19×8mm form factor, white segments on a black surface (enhancing contrast), and exceptional luminous intensity (180-220mcd/LED), it ensures visibility even in bright industrial environments or dim indoor spaces. Its low power consumption, big viewing angle, and RoHS compliance make it ideal for 24/7 operation—while multi-color options adapt to diverse functional needs (e.g., red for alerts, green for "normal" status).

Key Features

1. Instrument Panel-Optimized Design

Triple-Digit Layout: Supports numeric ranges from 000–999, perfect for displaying temperature (e.g., "-10°C" to "99°C"), humidity (e.g., "30%" to "90%"), or pressure (e.g., "120 PSI")—eliminating the need for additional displays for small-to-medium value metrics.

0.56-Inch (14.2mm) Character Height: Balances readability (from 1–2 meters, typical instrument viewing distance) and space efficiency—fits into dense instrument panels without overshadowing buttons, sensors, or other components.

White Segments on Black Surface: Creates sharp contrast with pure green light, ensuring digits and decimal points (critical for precise readings like "23.5°C") stand out—reducing the risk of misinterpreting data in fast-paced industrial settings.

2. Superior Visibility & Performance

Ultra-Bright Pure Green Illumination: 180-220mcd/LED intensity and 512-515nm wavelength cut through ambient glare (e.g., factory floor lights, sunlight through office windows) while remaining gentle on the eyes for prolonged monitoring.

Big Viewing Angle: Wide horizontal and vertical visibility ensures the display is readable from off-center positions (e.g., technicians standing beside an instrument panel, homeowners checking AC controls)—no need to lean in for clarity.

Stable Operation: Engineered to withstand voltage fluctuations (common in industrial power supplies) and temperature variations (0°C–50°C, typical operating range), maintaining consistent brightness and segment uniformity—no flickering or dimming during critical measurements.

3. Energy Efficiency & Easy Integration

Low Power Consumption: Optimized forward voltage (2.8-3.3V/LED) and forward current (10-15mA/LED) minimize energy use—ideal for battery-powered portable instruments or energy-efficient fixed panels (e.g., smart AC controllers).

Common Cathode Polarity: Compatible with standard driver ICs (e.g., TM1637, MAX7219) commonly used in instruments and home appliances, simplifying circuit design and accelerating product development.

Easy Assembly: Designed for hassle-free PCB mounting, supporting automated production lines for high-volume manufacturing—no specialized tools or custom brackets required.

4. Reliability & Compliance

Good Consistency: Tight tolerance in luminous intensity and color ensures uniform performance across batches—critical for instrument manufacturers needing consistent display quality in large-scale productions.

Long Lifespan: High-quality LED chips ensure a typical lifespan of 50,000+ hours—matching the 5–10 year service life of most instruments and home appliances, reducing maintenance costs.

RoHS Compliant: Meets international environmental and safety standards, ensuring compatibility with global markets (Europe, North America, Asia)—no regulatory barriers for export.
