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, home appliance settings, or digital counters.
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 or tiny home appliances. 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 for precision metrics but small enough for handheld instruments.
Common Anode Polarity: Works with standard instrument driver ICs—simplifies circuit design, no need for custom polarity adapters, and integrates seamlessly with instrument firmware.
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 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 that could impact device performance or safety.
Stable Luminous Output: No "hot spots" or uneven brightness across segments, ensuring every bar of digits 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 — extends battery life by 30% compared to higher-current displays, reducing user hassle of frequent charging.
Stable Operation in Variable Environments: Withstands temperature fluctuations and minor vibrations—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, green, amber, orange, and white—flexible for functional cues 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 and industrial instruments, meeting global safety standards for export to EU, North America, and Asia.
