Product Main Image Area
(Recommend 4-6 high-definition visuals to highlight key features)
Luminous Close-Up: Clear shot of dual digits (e.g., "25" or "08") in ultra bright white, with yellow segments and black surface—showcasing no "hotspots" or dim edges for consistent readability.
Dimension Labeled Diagram: Marked 25×19×8mm outer dimensions and 14.2mm (0.56-inch) digit height, visualizing the compact profile for space-constrained devices.
Wide Viewing Angle Test: Side-angle shots (matching X/Y 0.29-0.31) to demonstrate clear visibility from off-center positions (e.g., viewing a control panel from the side).
Application Mockup: Integrated into a home appliance (e.g., thermostat showing "22℃") or industrial indicator (e.g., process counter showing "50") to reflect real-world use.
Parameter Detail Shot: Close-up of "Common Cathode (CC)" marking and RoHS logo, reinforcing compliance and polarity clarity.
Key Selling Points
1. Ultra Bright White Luminosity & Uniform Segments
120-140mcd high luminous intensity: The ultra bright white emission cuts through bright ambient light (e.g., kitchen overhead lights, industrial workshop lighting) without glare—critical for "at-a-glance" readouts (e.g., checking a thermostat’s "25℃" or a counter’s "99" count). Unlike lower-brightness displays (80-100mcd), it avoids squinting or misreading in well-lit environments.
Continuous uniform segments: Advanced LED placement and light-diffusing yellow segments ensure no "dark spots" (e.g., a faded segment in "8" mistaken for "3"). This uniformity is essential for precision applications like digital indicators, where even small visual errors could lead to operational mistakes.
2. Compact Design & Wide Viewing Angle
25×19×8mm miniaturized form: The slim 8mm depth and compact footprint fit seamlessly into small devices—e.g., portable thermometers, smart switch panels, or mini industrial counters—without requiring bulky enclosures. Ideal for product designs prioritizing sleek aesthetics.
X/Y 0.29-0.31 wide viewing angle: Clear visibility from off-center positions (e.g., a user standing to the side of a wall-mounted thermostat) eliminates the need to align directly with the display. Perfect for shared spaces (e.g., offices, kitchens) where users interact with devices from multiple angles.
3. Energy Efficiency & Heat Management
Low power consumption (5-10mA per LED): Extremely low current draw reduces energy use, making it suitable for battery-powered devices (e.g., wireless temperature sensors) or 24/7 operated equipment (e.g., industrial process monitors). Extends battery life by 30-40% compared to higher-current displays.
Fast heat-dissipation: The display’s thermal design prevents heat buildup (even during continuous use), avoiding performance degradation (e.g., brightness dimming) or component damage. Critical for devices with limited ventilation (e.g., sealed appliance panels).
4. Easy Integration & Customization
IC compatibility: Works seamlessly with common 7-segment driver ICs, eliminating the need for custom circuit design. Simplifies assembly for manufacturers and reduces R&D time for new products.
Customizable options: Supports tailored modifications to fit specific needs—e.g., adjusted segment spacing for unique panel layouts, decimal point position (e.g., for temperature "22.5℃"), or matching yellow segment shades to brand aesthetics.
Easy assembly: Standardized pin layout and compact size enable automated SMT (Surface Mount Technology) or manual through-hole installation, reducing production errors and speeding up manufacturing.
Target Applications
1. Home Appliances
Thermostats/humidifiers: Display temperature (e.g., "22℃") or humidity (e.g., "55%").
Microwaves/induction cooktops: Show cook time (e.g., "02:30") or power levels (e.g., "70").
Small kitchen appliances (blenders/toasters): Indicate speed settings (e.g., "3") or toasting levels (e.g., "5").
2. Industrial & Commercial Indicators
Process counters: Track production units (e.g., "99" pieces) or machine cycles (e.g., "50" runs).
Environmental monitors: Display temperature (e.g., "28℃") or pressure (e.g., "100kPa") in workshops/warehouses.
Power supplies/voltage meters: Show output voltage (e.g., "12V") or current (e.g., "0.5A").
3. Consumer Electronics
Portable measurement tools: Handheld thermometers (e.g., "37.5℃") or digital scales (e.g., "5.0kg").
Smart home devices: Smart switches (e.g., "01" for channel 1) or battery chargers (e.g., "80" for 80% capacity).
Quality Assurance
Brightness & Uniformity Testing: Every unit undergoes luminous intensity checks (120-140mcd) and segment uniformity inspections to ensure no visual defects.
Environmental Stability: Samples are tested for 24-hour operation at -40℃~85℃ to verify performance under extreme temperatures, with fast heat-dissipation validated via thermal imaging.
Warranty: 1-year warranty for non-human damage. If the display fails due to manufacturing defects (e.g., segment dimming, heat-related issues), free replacement is provided (batch number required).
Frequently Asked Questions (FAQ)
Q: Can the display be customized to add a decimal point?
A: Yes—decimal points can be added to one or both digits (e.g., "22.5" for temperature) to support precision readouts.
Q: Is the yellow segment color customizable to match my device’s aesthetic?
A: Absolutely—we offer adjustable yellow shades (e.g., warm yellow, bright yellow) to align with your product’s design language.
Q: Does the wide viewing angle affect brightness?
A: No—even at maximum viewing angles (X/Y 0.29-0.31), brightness remains within 10% of the front-facing intensity, ensuring consistent readability.
