Luminosity Evenly distributed across all segments (no hotspots or dim edges)
Form Factor Industrial standard size (compatible with off-the-shelf PCBs/enclosures)
Environmental Performance Excellent reliability in bright ambient light (no fading in sunlight/strong indoor lighting)
Compliance

RoHS/REACH compliant (free from restricted substances/hazardous chemicals)

 

Core Product Features
1. Ultra Bright Visibility for All Environments
Ultra bright white emission + optimized forward voltage:
The white hue delivers exceptional contrast against most device housings (black, gray, or white appliance panels) and cuts through bright ambient light—from sunlit retail displays to industrial factory floors. The optimized forward voltage ensures maximum luminous intensity without wasting power, making digits (0-9, plus decimal points for precision) readable at a glance. Critical for applications like process indicators or temperature monitors, where misreading a value could lead to operational errors.
Evenly distributed luminosity: Light spreads uniformly across all 3 digits and 7 segments, eliminating "dark spots" or faded edges that distort numbers (a partially dim "8" mistaken for "3" in production counts). This consistency guarantees reliable readability across the display’s entire lifespan, reducing the need for frequent replacements.
2. Energy Efficiency for Sustained Use
Low power consumption + extremely low current: Minimizes energy draw, offering dual benefits for end-users and manufacturers:
Battery-powered devices:
Portable thermometers, handheld humidity meters, or wireless process sensors.
24/7 operated equipment: Industrial process monitors, home appliance control panels, or multimedia devices–cuts long-term electricity costs and reduces heat generation.
3. Industrial-Grade Reliability & Durability
Stable performance + long lifespan:
Built with high-quality LED chips and robust encapsulation to resist voltage fluctuations (common in home/industrial power circuits) and mechanical vibration. Supports 50,000+ hours of continuous operation (over 5 years of 24/7 use), ensuring consistent functionality in high-use environments.
Industrial standard size: Compatible with off-the-shelf PCBs, sockets, and enclosures—no custom machining or modified hardware needed. Simplifies integration into existing designs (upgrading old process indicators or retrofitting multimedia products) and speeds up production for manufacturers, reducing R&D time and costs.
4. Regulatory Compliance & Versatility
RoHS/REACH compliant:
Free from lead, mercury, cadmium and hazardous chemicals, meeting global regulations for consumer electronics, industrial equipment, and multimedia devices. Ensures eligibility for export to key markets like the EU, North America, and Asia, and aligns with eco-friendly product initiatives.
Universal application fit: The triple-digit layout is ideal for values requiring 1-3 digits, making it suitable for:
Process metrics: "0-999kPa" (pressure), "0-999L/min" (flow rate).
Multimedia: "001-999" (channel numbers), "00:00-99:59" (playback time).
Target Applications
Optimized for triple-digit numeric display needs across consumer, commercial, and industrial sectors:
Numeric Displays: Retail price tags , queue number indicators , or digital signage.
Multimedia Products: Set-top boxes , media players , or gaming consoles.
Temperature/Humidity Indicators: Industrial thermostats, home smart humidistats, or warehouse environmental monitors.
Process Indicators: Factory production counters , pressure gauges , flow rate monitors, or chemical dosage indicators.
