0.4-Inch (10.16mm) 7-Segment LED Display – Ultra Bright White,
Yellow Epoxy & Black Surface
Luminous Close-Up: Clear shot of the ultra bright white digit (e.g., "5" or "9") with
yellow epoxy and black surface—showcasing even light distribution
across all segments (no "hotspots" or dim edges).
Dimension Labeled Diagram: Marked 30.1×16×7mm outer dimensions and 10.16mm (0.4-inch)
character height, emphasizing the slim 7mm depth for
space-constrained devices.
Material Detail Shot: Close-up of the yellow epoxy coating and black surface,
highlighting durability and the industrial-grade build.
Application Mockup: Integrated into audio equipment (e.g., amplifier volume "3"),
instrument panel (e.g., temperature "22℃"), or multimedia device
(e.g., media player track "08") to reflect real-world use.
Multi-Color Option Shot: Side-by-side display of available emitting colors (white, red,
blue, green, etc.) to illustrate customization flexibility.

Key Selling Points
1. Ultra Bright White & Even Luminosity – Clear Readability in All
Scenes
High luminous intensity via optimized forward voltage: The display’s forward voltage is calibrated to maximize white
light output—bright enough to cut through ambient glare (e.g.,
living room lamps, studio lights) but not harsh on the eyes.
Perfect for "at-a-glance" readouts, like checking an amplifier’s
volume or a temperature indicator’s reading.
Even light distribution across segments: Advanced LED placement and yellow epoxy diffusion ensure no
segment is dimmer than others (e.g., the top bar of "8" won’t fade
compared to the bottom bar). This uniformity avoids misreading
(e.g., "6" mistaken for "0")—critical for precision applications
like process indicators.
2. Industrial Standard Size & Slim Design – Easy Integration
30.1×16×7mm industrial standard dimensions: No need to modify PCBs or enclosures—fits seamlessly into
off-the-shelf compact devices (e.g., mini audio receivers, portable
temperature monitors). The 7mm slim depth keeps products sleek,
avoiding bulky protrusions from panels.
Yellow epoxy + black surface durability: The yellow epoxy coating resists scratches from daily use (e.g.,
wiping audio equipment) and minor impacts, while the black matte
surface reduces reflection. Ensures long-term performance in
high-use scenarios (e.g., a studio amplifier used daily).
3. Low Power Consumption – Energy-Efficient for All Devices
Minimal current draw (5-10mA/LED): Reduces energy use, making it ideal for battery-powered devices
(e.g., wireless temperature sensors) or 24/7 operated equipment
(e.g., always-on audio receivers). Extends battery life by 30%
compared to higher-power displays and aligns with eco-friendly
product certifications.
4. Multi-Color Flexibility & Global Compliance
7 optional emitting colors: Beyond ultra bright white, choose from red (for alerts), blue (for
modern aesthetics), green (for "normal" status), or amber (for
warmth)—matching your product’s design language (e.g., blue for a
sleek multimedia player, red for a industrial process alarm).
RoHS/REACH compliance: Meets strict global environmental standards, ensuring eligibility
for export to the EU, North America, and Asia. No barriers to
selling in international markets.
Target Applications
1. Audio & Multimedia Equipment
Amplifiers/preamps: Display volume levels (e.g., "0-10"), input channels (e.g., "1"
for AUX, "2" for Bluetooth), or equalizer settings (e.g., "3" for
bass boost).
Media players/streamers: Show track numbers (e.g., "12"), playback time (e.g., "45:10"), or
signal strength (e.g., "5" for full signal).
Radio receivers: Indicate frequency (e.g., "98.7" MHz) or station presets (e.g.,
"1" for favorite station).
2. Instrument & Process Indicators
Temperature/humidity monitors: Display readings (e.g., "25℃", "50%RH") in homes, offices, or
warehouses.
Process indicators: Track production counts (e.g., "150" units) or machine status
(e.g., "1" for "running", "0" for "idle") in small factories.
Battery chargers: Show charge levels (e.g., "80" for 80% capacity) or charging
status (e.g., "1" for "charging", "2" for "full").
3. General Digital Indicators
Portable measuring tools: Handheld thermometers (e.g., "37.5℃") or digital calipers (e.g.,
"10.2mm").
Smart home devices: Smart switches (e.g., "1" for "on", "0" for "off") or light
dimmers (e.g., "5" for 50% brightness).
