Super Bright Red 20mm (0.8-Inch) 4-Digit 7-Segment Common Anode LED
Display for Instrument Panels
Product Overview
Introducing the Super Bright Red 20mm (0.8-Inch) 4-Digit 7-Segment
Common Anode LED Display—a high-visibility, multi-digit solution
engineered for instrument panels, home appliances, and precision
indicators. Designed to prioritize large-scale readability, energy
efficiency, and reliable performance, this 4-digit display excels
at showing complex metrics: industrial instrument values (e.g.,
“2200” for voltage), home appliance timers (e.g., “0600” for 60
minutes), or temperature/humidity data (e.g., “30.5°C”).
Its 20mm (0.8-inch) character height ensures exceptional
readability from 1–3 meters (typical for instrument panel viewing
in factories or home kitchens), while the 71.6×25.8×8.5mm profile
fits into standard large-format control panels—no bulky redesigns
required. The white segments on a black surface create sharp
contrast with super bright red light (50-65mcd), cutting through
ambient glare (e.g., factory overhead lights, kitchen sunlight)
without eye strain.
With common anode polarity, low power consumption (5-10mA/LED), and
RoHS compliance, this display balances durability,
eco-friendliness, and functionality—ideal for 24/7 operation in
instrument panels and high-use home appliances.

Key Features (Instrument Panel-Optimized)
1. Large-Digit Visibility for Clear Readouts
20mm (0.8-Inch) Character Height: Among the larger 4-digit displays, it’s visible from across rooms
or factory floors—critical for technicians monitoring instrument
panels from a distance (e.g., checking “3800V” power readings
without leaning in).
Super Bright Red Illumination (50-65mcd): Red light is highly
distinguishable in industrial or home environments, avoiding
confusion with background lights. It stands out for critical values
(e.g., “HIGH 150” process alerts) while remaining gentle on eyes
during prolonged viewing.
White Segments on Black Surface: High contrast eliminates “washout” and ensures every digit (0-9)
and decimal point (e.g., “25.5°C”) is crisp—no misreading “8” as
“0” or “3” as “5” in fast-paced industrial settings.
2. Energy Efficiency & Stable Performance
Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes energy use for 24/7-run
instruments (e.g., factory power monitors) and extends battery life
for portable indicators (e.g., handheld temperature meters).
Optimized Forward Voltage (1.8-2.2V/LED): Compatible with standard
5V/12V power supplies used in instrument panels and home
appliances—no need for custom voltage converters, simplifying
circuit design.
Stable Operation in Variable Environments: Withstands temperature fluctuations (-10°C to 60°C, typical for
factories, kitchens, or outdoor-covered panels) and minor
vibrations (e.g., factory machinery, appliance fan movement).
Maintains consistent brightness, no flickering during value
updates.
3. Easy Integration & Durability
Common Anode Polarity: Works with standard driver ICs (e.g., MAX7219, TM1638, HT1621)
widely used in instrument panels—simplifies circuit design for
manufacturers and supports seamless integration with existing
firmware (e.g., sensor data processing, error code generation).
Easy-to-Assemble Design: Compatible with PCB direct-mounting and automated production
lines—speeds up manufacturing for high-volume instruments (e.g.,
1000+ power monitors) and ensures consistent alignment in control
panels.
Long Lifespan (50,000+ Hours): High-quality red LED chips match the 8–10 year service life of
most industrial instruments and home appliances—eliminates downtime
from frequent display replacements, reducing maintenance costs.
4. Versatility & Compliance
Multi-Color Options: Beyond super bright red, available in blue (modern aesthetics),
yellow green (eco-aligned designs), pure green, amber, orange, and
pure white—flexible for functional cues (e.g., green for “normal”
status, red for “alerts”) or brand-specific instrument designs.
RoHS Compliant: Free from lead, mercury, and harmful substances—safe for use in
consumer home appliances (e.g., large ovens) and export to global
markets (EU, North America, Asia), meeting industrial safety
standards.
