Super Bright Red 7mm (0.28-Inch) 2-Digit 7-Segment Common Anode LED Display for Instrument Panels

Product Overview

Introducing the Super Bright Red 2-Digit 7-Segment Common Anode LED Display—a miniaturized, high-visibility solution engineered for instrument panels, home appliances, and compact digital indicators. Designed to prioritize space efficiency, clear readability, and industrial-grade reliability, this 2-digit display excels at showing concise metrics: instrument values (e.g., "30" for voltage, "05" for current), home appliance settings (e.g., "18" for oven temp, "02" for fan speed), or digital counters (e.g., "99" for cycle counts).

Its 7mm (0.28-inch) digit height balances readability (clear from 0.3–1.5 meters, typical for instrument operation) and miniaturization, while the 15×12×6.1mm form factor fits into dense PCB layouts—critical for instrument panels with multiple displays or tiny home appliances. The white segments on a black surface creates sharp contrast with super bright red light (630-635nm), cutting through ambient glare (e.g., workshop lights, kitchen sunlight) without eye strain, and standing out for critical values.

With common anode polarity, low power consumption, and RoHS compliance, this display thrives in industrial and home environments alike—ideal for 24/7 operation in instrument panels and daily-use devices.

Key Features (Instrument Panel-Optimized)

1. Ultra-Compact Design for Space-Limited Use

Miniature Dimensions (15×12×6.1mm): Among the smallest 2-digit 7-segment displays, fitting into dense instrument panels (e.g., multi-parameter testers with 4+ displays) or tiny home appliances (e.g., mini humidifiers, portable thermometers). No need to resize PCBs or redesign device enclosures for value readouts.

7mm (0.28-Inch) Digit Height: Balances small size with readability—large enough to distinguish digits (e.g., "0" vs. "8") for precision metrics (e.g., "05" for 5V) but small enough for handheld instruments (e.g., portable voltage testers).

Common Anode Polarity: Works with standard instrument driver ICs (e.g., TM1637, HT1621, MAX7219)—simplifies circuit design, no need for custom polarity adapters, and integrates seamlessly with instrument firmware (e.g., sensor data processing, error code display).

2. Superior Visibility for Critical Readouts

Super Bright Red Illumination (50-60mcd, 630-635nm): Red light is highly distinguishable in industrial and home environments, avoiding confusion with background lights. It stands out for critical values (e.g., "99" for max capacity, "00" for reset) while remaining gentle on eyes during prolonged viewing.

White Segments on Black Surface: High contrast eliminates "washout" and fuzzy edges on small digits—critical for accurate reading of fine values (e.g., "08" for 8mA in instrument tests) that could impact device performance or safety.

Stable Luminous Output: No "hot spots" or uneven brightness across segments (laboratory-tested <2% intensity variation), ensuring every bar of digits (e.g., the middle bar of "5") is consistent—avoids misinterpretation of values.

3. Energy Efficiency & Durable Performance

Low Power Consumption (5-10mA/led): Extremely low current draw minimizes energy use, ideal for battery-powered instruments (e.g., handheld testers) — extends battery life by 30% compared to higher-current displays, reducing user hassle of frequent charging.

Stable Operation in Variable Environments: Withstands temperature fluctuations (-10°C to 50°C, typical for workshops, kitchens, or equipment enclosures) and minor vibrations (e.g., instrument movement, appliance fan operation)—maintains consistent brightness, no flickering during value updates.

Long Lifespan (50,000+ Hours): High-quality red LED chips match the 5–8 year service life of most instruments and home appliances—eliminates maintenance downtime from frequent display replacements, lowering long-term costs.

4. Versatility & Compliance

Multi-Color Options: Beyond super bright red, available in blue (modern aesthetics), green (eco-aligned designs), amber, orange, and white—flexible for functional cues (e.g., green for "normal" status, red for "alert") or brand-specific instrument/appliance designs.

Easy Assembly: Compatible with PCB direct-mounting and automated production lines—speeds up manufacturing for high-volume instruments/appliances and ensures consistent alignment in control panels, reducing manual labor errors.

RoHS Compliant: Free from lead, mercury, and harmful substances—safe for consumer home appliances (e.g., kitchen timers) and industrial instruments (e.g., factory sensors), meeting global safety standards for export to EU, North America, and Asia.

Technical Specifications

Applications
