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 (extends battery life by 30-40% vs. higher-current
displays, reducing replacement frequency).
24/7 operated equipment: Industrial process monitors, home appliance control panels
(refrigerator thermostats), or multimedia devices (set-top boxes) –
cuts long-term electricity costs and reduces heat generation
(critical for enclosed electronics).
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 (in factory equipment or
portable tools). 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 (RoHS) and hazardous chemicals
(REACH), 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 (sustainable smart
home lines, energy-efficient industrial tools).
Universal application fit: The triple-digit layout is ideal for values requiring 1-3 digits,
making it suitable for:
Temperature/humidity: "-20°C" to "99°C", "0-99% RH".
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.
