Ultra Bright White 7 Segment LED Display Triple Digit Common Anode

Ultra Bright White 0.4-Inch 3-Digit 7-Segment LED Display (Common Anode, Yellow Epoxy Black Surface) for Numeric & Process Indicators

Product Overview
Introducing the Ultra Bright White 0.4-Inch 3-Digit 7-Segment LED Display—a compact, high-performance numeric solution engineered for numeric displays, multimedia products, and precision indicators (temperature, process, etc.). Designed to balance clarity, energy efficiency, and industrial compatibility, this 3-digit display excels at showing detailed metrics that demand readability: temperature (e.g., “22.5°C” for thermostats), process timers (e.g., “090” for 90 seconds), or multimedia settings (e.g., “050” for volume levels).
Its 0.4-inch character height ensures visibility from 1–2 meters (typical user distance for counters, controllers, or multimedia devices), while the slim 30.1×16×7mm form factor fits seamlessly into space-constrained panels—from mini temperature sensors to compact audio amplifiers. The yellow epoxy black surface enhances contrast with ultra bright white light, avoiding glare while ensuring segments remain sharp in both dim and bright environments. With common anode polarity, low power consumption, and RoHS/REACH compliance, it combines reliability, eco-friendliness, and easy integration—ideal for 24/7 operation in home, commercial, and light industrial settings.

Key Features (Indicator & Multimedia-Optimized)
1. Eye-Friendly Ultra Bright White Illumination
Versatile White Light: Ultra bright white illumination delivers neutral, easy-to-read light that works across scenarios—no color bias (unlike red/blue) makes it ideal for temperature indicators (where “25°C” needs clear, undistracted readout) and multimedia devices (where volume/channel numbers blend with modern designs).
Yellow Epoxy Black Surface: The unique yellow epoxy base under the black surface softens harsh white light (reducing eye strain) while boosting contrast between segments and background—ensures digits stay visible without glare, even in direct indoor light (e.g., office lamps, kitchen overheads).
Even Segment Lighting: Segments are uniformly lit (no “hot spots” or dim edges), so every digit (e.g., “0” to “9”) and decimal point (for precision metrics like “15.8°C”) is crisp—avoids misreading values that could disrupt process timing or temperature control.
2. Compact & Industrial-Grade Design
Slim 30.1×16×7mm Dimensions: Optimized for space-constrained devices—fits into mini temperature controllers, portable process indicators, or slim multimedia remotes without requiring panel redesigns.
Industrial Standard Size: Follows industry benchmarks for 0.4-inch 3-digit displays, ensuring drop-in compatibility with existing PCB layouts (e.g., upgrading old single-color displays to white in factory process indicators) — cuts development time for manufacturers.
Common Anode Polarity: Works with standard driver ICs (e.g., TM1638, MAX7219) widely used in numeric indicators and multimedia products—simplifies circuit design, no need for custom polarity adapters.
3. Energy Efficient & Durable
Low Power Consumption (Extremely Low Current): Minimizes energy draw (typical 5-10mA/LED), making it ideal for battery-powered devices (e.g., portable temperature sensors) or energy-efficient electronics (e.g., ENERGY STAR-certified multimedia gear)—extends battery life by 25-30% compared to higher-current displays.
Long Lifetime (50,000+ Hours): High-quality white LED chips withstand continuous use, matching the 8–10 year service life of most indicators and multimedia devices—reduces maintenance costs (critical for 24/7 process indicators in factories).
Stable Performance: Withstands temperature fluctuations (0°C–50°C, typical for homes, offices, and light industrial spaces) and minor vibrations (e.g., factory equipment, multimedia speaker bass)—maintains consistent brightness, no flickering during value updates.
4. Compliance & Versatility
RoHS/REACH Compliant: Free from lead, mercury, and harmful phthalates—meets strict global safety standards, ensuring use in consumer products (e.g., home temperature monitors) and industrial devices (e.g., factory process indicators) exported to EU, North America, and Asia.
Multi-Color Options: Beyond ultra bright white, available in red, blue, green, amber, orange, and yellow—flexible for functional cues (e.g., red for “high temp” alerts, white for standard readouts) or brand-specific designs (e.g., blue for premium multimedia lines).
