Super green 0.56" common cathode single digit 7 segment led display for instrument panel

Product Overview

Introducing the Super Bright Yellow Green 0.56-Inch Single-Digit 7-Segment Common Cathode LED Display—a compact, high-reliability numeric solution engineered for instrument panels, home appliances, and digital indicators. Designed to deliver clear, energy-efficient readouts of single-digit values (e.g., "5" for temperature settings, "9" for volume levels), this display combines a 0.56-inch (14.20mm) character height for easy visibility with a slim 12.6×19×8mm form factor—perfect for space-constrained devices where every millimeter matters.

With white segments on a black surface (enhancing contrast), super bright yellow green illumination (569-573nm wavelength), and common cathode polarity, it integrates seamlessly into existing control boards. Its low power requirement, long lifetime, and RoHS compliance make it ideal for 24/7 operation, while multi-color options (red, blue, white, etc.) adapt to diverse design and functional needs—from industrial instruments to household appliances.

Key Features

1. Compact Design for Space-Constrained Devices

Ultra-Slim 12.6×19×8mm Size: Fits into tight spots in instrument panels (e.g., alongside sensors or buttons) and small home appliances (e.g., mini microwaves, portable thermometers)—no bulk to compromise device ergonomics.

0.56-Inch (14.20mm) Character Height: Balances readability (from 0.5–1.5 meters, typical user distance) and compactness. Digits are large enough to avoid eye strain but small enough for multi-display tiling (e.g., 4 units for a 4-digit temperature readout like "25.8°C").

White Segments on Black Surface: Creates sharp contrast with yellow green light, ensuring digits stand out in bright environments (e.g., factory floors) or dim spaces (e.g., kitchen cabinets)—critical for quick, accurate readings.

2. Superior Visibility & Efficiency

Super Bright Yellow Green Illumination: 30-42mcd luminous intensity and 569-573nm wavelength deliver vivid, easy-to-recognize light that cuts through ambient glare. Yellow green is also less harsh on the eyes than red or blue, making it ideal for prolonged use (e.g., daily appliance checks).

Low Power Requirement: Optimized forward voltage (1.8-2.3V/LED) and forward current (10-15mA/LED) minimize energy use—extending battery life for portable devices (e.g., handheld temperature sensors) and reducing electricity costs for plugged-in appliances.

Stable Performance: Engineered to withstand temperature fluctuations (0°C–50°C, typical operating range) and minor vibrations (e.g., from appliance motors), maintaining consistent brightness and segment clarity over time—no flickering or dimming.

3. Easy Integration & Durability

Common Cathode Polarity: Compatible with standard driver ICs (e.g., TM1637, MAX7219) commonly used in instruments and appliances, simplifying circuit design and eliminating the need for custom modifications.

Easy Assembly: Designed for hassle-free PCB mounting, supporting automated production lines for high-volume manufacturing. No specialized tools or brackets are required, reducing assembly time and labor costs.

Long Lifetime: High-quality LED chips ensure a typical lifespan of 50,000+ hours—matching the 3–10 year service life of most instruments and appliances, minimizing maintenance and replacement expenses.

4. Compliance & Versatility

RoHS Compliant: Meets international environmental and safety standards, free from harmful substances (lead, mercury) to align with global regulations for consumer and industrial products.

Multi-Color Options: Beyond yellow green, choose from ultra bright red (for alerts), ultra bright blue (for branding), pure green, pure white, amber, or orange—flexible for functional cues (e.g., red for "high temp," green for "normal").

Technical Specifications

Applications

This single-digit LED display is versatile across consumer and industrial scenarios:

Instrument Panels: Industrial pressure gauges, flow meters, or voltage monitors (for single-digit metrics or decimal placeholders).

Home Appliances: Mini microwaves (timer digits), portable thermometers (temperature values), electric kettles (heat level indicators), or humidifiers (humidity percentage digits).

Digital Indicators: Battery chargers (charge level digits), countdown timers (minute/second placeholders), or fitness equipment (workout metric digits).

Consumer Electronics: Smart home sensors (e.g., "1" for "ON," "0" for "OFF") or small audio devices (volume level indicators).
