0.4-Inch (10.16mm) Triple-Digit 7-Segment LED Display – Ultra Bright White for Precision Indicators & Multimedia
Product Overview
This triple-digit 7-segment LED display is engineered for high-efficiency, high-visibility numeric readouts across consumer, commercial, and industrial devices—featuring a 0.4-inch (10.16mm) character height, compact outer dimensions (30.1×16×7mm), and vivid ultra bright white emission. Built with a durable "yellow epoxy + black surface" design, it balances contrast and durability, while optimized electrical parameters (1.8-2.2V forward voltage, 5-10mA forward current) deliver exceptional luminosity without excess power draw. Key strengths include uniform segment illumination, superior readability in intense ambient light, and extended service lifespan—making it ideal for 24/7 operated devices like temperature/humidity indicators, multimedia products, and industrial process monitors. Fully RoHS/REACH compliant and supporting 6 additional emission colors (red, blue, green, etc.), its industrial-standard size ensures easy integration into existing designs, positioning it as a versatile solution for precision-focused numeric display needs.

Core Product Features
1. High-Efficiency Luminosity & Energy Savings
Optimized forward voltage (1.8-2.2V): Tailored to maximize luminous intensity while minimizing power waste. Unlike generic displays with higher voltage requirements, it operates seamlessly with standard low-voltage circuits (e.g., 3.3V or 5V systems), reducing the need for voltage regulators and cutting energy consumption by 25-30% compared to non-optimized alternatives.
Ultra-low operating current (5-10mA) + energy-saving design: Ideal for:
Battery-powered devices: Portable temperature monitors, handheld humidity meters, or wireless process sensors (extends battery life by 30-40%, reducing replacement frequency for end-users).
24/7 operated equipment: Multimedia set-top boxes, industrial process indicators, or home appliance control panels (lowers long-term electricity costs and heat buildup in enclosed enclosures).
2. Superior Visibility & Durability
Ultra bright white emission + yellow epoxy + black surface: The white hue delivers exceptional contrast against most device housings, while the yellow epoxy enhances light diffusion and resists scratches from daily use. Critical for readability in intense ambient light—from sunlit retail displays to factory floors—where dimmer displays fade or become unreadable.
Uniform segment illumination: Light distributes evenly across all 3 digits and 7 segments, eliminating "dark spots" that distort multi-digit values. This consistency is vital for precision applications like temperature readings, where even small misreads can cause operational errors.
3. Industrial-Grade Reliability & Longevity
Consistent operational stability: Built with high-quality LED chips and robust yellow epoxy encapsulation to resist voltage fluctuations and mechanical vibration. Ensures no flickering, segment dropout, or brightness degradation over time—even in harsh environments.
Extended service lifespan (exceeding industry averages): Supports 50,000+ hours of continuous operation (over 5 years of 24/7 use), outperforming standard displays (30,000-40,000 hours). Reduces maintenance downtime and replacement costs for commercial/industrial users.
4. Seamless Integration & Versatility
Global industrial dimensional standards: 30.1×16×7mm dimensions fit off-the-shelf PCBs, sockets, and enclosures—no custom machining or modified hardware needed. Simplifies integration into existing designs and speeds up production for manufacturers, reducing R&D time and costs.
Multi-color flexibility: Beyond ultra bright white, 6 additional colors cater to functional and aesthetic needs:
Red: For "alert" statuses .
Blue/Green: For modern smart home devices
Amber/Orange: For retro-style appliances
Target Applications
Optimized for triple-digit numeric display needs across diverse sectors:
Numeric Displays: Retail price tags, queue number indicators , digital signage , or parking garage level markers.
Multimedia Products: Set-top boxes , media players , gaming consoles , or soundbars.
Temperature/Humidity Indicators: Industrial thermostats (e.g., "80°C"), home smart humidistats (e.g., "55% RH"), warehouse environmental monitors , or sous vide machine controls.
Process Indicators: Factory production counters , pressure gauges , flow rate monitors , or chemical dosage indicators .
