Yellow Green Triple Digit 7 Segment LED Display Common Anode
Product Overview
Introducing the Yellow Green 3-Digit 7-Segment Common Anode LED
Display—a high-reliability numeric solution engineered for
precision indicators (temperature, humidity, process) and general
digital readouts. Designed to prioritize long-term performance,
energy efficiency, and seamless integration, this display excels at
delivering consistent, glare-free values in demanding
environments—from bright industrial floors to climate-controlled
labs.
Its yellow green illumination strikes a balance between visibility
and eye comfort: vivid enough to cut through high-light conditions
(e.g., factory overhead lights) but soft enough for prolonged
viewing (e.g., lab technicians monitoring process timers). The
common anode configuration simplifies compatibility with standard
driver ICs, while the standardized footprint enables drop-in
replacement for existing displays—eliminating costly PCB redesigns.
With a 100,000+ hour mean time between failures (MTBF) and nano-amp
level current draw, it’s built for maintenance-free operation in
both commercial and industrial settings.

Key Features (Indicator-Optimized Performance)
1. Precision Brightness & Visibility
Precision Voltage Regulation: Ensures consistent maximum brightness output across all segments,
even with minor voltage fluctuations (common in industrial power
supplies). No “dim segments” or uneven lighting—critical for
accurate reading of fine metrics (e.g., “22.1°C” vs. “22.3°C” in
temperature indicators).
Anti-Glare Optimization: Specialized surface treatment minimizes reflection in high-light
environments (e.g., sunny control rooms, factory floors with
overhead LEDs). Values remain clear without squinting, reducing
user fatigue during long shifts.
Balanced Light Diffusion: Nano-coating on segments ensures uniform light
distribution—eliminates hot spots (e.g., overly bright segment
edges) and guarantees consistent readability from any angle (ideal
for shared indicator panels in busy facilities).
2. Ultra-Low Energy & Sensitive Application Compatibility
Reduced Energy Expenditure: Engineered for efficiency—delivers full brightness while using
20-30% less power than standard 3-digit displays. Lowers
operational costs for 24/7-run indicators (e.g., server room
temperature monitors).
Nano-Amp Level Current Draw: Extremely low standby and operating current makes it safe for
sensitive applications (e.g., battery-powered portable humidity
sensors, medical device indicators where current fluctuations could
disrupt other components).
Stable Signal Integrity: Maintains flawless communication with driver ICs throughout
operational cycles—no signal dropouts or flickering during value
updates (critical for process indicators tracking time-sensitive
manufacturing steps).
3. Durability & Easy Integration
100,000+ Hour MTBF Rating: Industrial-grade LED chips and robust packaging ensure
maintenance-free operation for 10+ years (based on 24/7 use).
Eliminates downtime from display replacements in critical systems
(e.g., industrial process controllers).
Standardized Footprint: Follows industry-standard dimensions for 3-digit 7-segment
displays—enables drop-in replacement for outdated or failed
displays (e.g., upgrading old red displays to yellow green in
existing humidity indicators) without modifying PCBs.
Common Anode Polarity: Compatible with widely used driver ICs (e.g., MAX7219, TM1638,
HT1621) — simplifies circuit design for new projects and ensures
backward compatibility with legacy indicator systems.
4. Reliable Operation Across Environments
Wide Temperature Tolerance: Operates seamlessly in -20°C to 60°C (-4°F to 140°F) — suitable
for harsh environments (e.g., cold storage temperature indicators,
hot factory process monitors) where standard displays might fail.
Moisture & Dust Resistance: Basic IP40-rated protection (optional IP65 for industrial
variants) shields internal components from dust and minor moisture
(ideal for warehouse humidity indicators or outdoor-facing
temperature displays in covered areas).

Applications
This display is tailored for precision and general-purpose
indicators across industries, including:
Temperature Indicators: Industrial process monitors (e.g., “180°C” for heating steps),
HVAC control panels (e.g., “23.5°C” for office temp), cold storage
thermometers (e.g., “-5°C” for refrigerated goods).
Humidity Indicators: Lab humidity controllers (e.g., “55% RH” for sample storage),
warehouse moisture monitors (e.g., “60% RH” for inventory
protection), portable environmental sensors.
Process Indicators: Manufacturing timers (e.g., “090” for 90 seconds of curing time),
