OEM ultra white & pure green 8 digit 7mm(0.28") 7 segment led display for instrument panel
Product Overview
Introducing our OEM Ultra White & Pure Green 8-Digit 7-Segment LED Display—a precision-engineered digital visualization solution tailored for high-demand instrumentation scenarios. Designed with a compact 0.28-inch (7mm) digit height and space-saving outer dimensions (22×38×7mm), this 8-digit display delivers exceptional readability, energy efficiency, and customization flexibility—making it the ideal choice for OEM projects, industrial controllers, and precision measurement devices.
What sets this display apart is its dual primary emitting colors: ultra white (for crisp, high-visibility numerical output) and pure green (for clear, eye-friendly readouts in low-light or extended-viewing environments). Built with common cathode polarity, it integrates seamlessly with standard electronic systems, while its "high luminous intensity + even light distribution" design ensures every digit (0-9) and symbol (e.g., "-", ".") remains sharp across all 8 segments—critical for applications like temperature/humidity monitors or process controllers where data accuracy cannot be compromised.
As an OEM-focused product, it supports tailored modifications to match your specific design requirements, ensuring alignment with your device's form factor, functionality, and brand aesthetic.

Why Choose This 8-Digit 7-Segment LED Display?
When selecting a display for precision instrumentation or OEM projects, reliability, performance, and adaptability are non-negotiable. Our 8-digit 7-segment display excels in all areas—here's why it's the smart choice for your next project:
1. Precision Readability for Critical Data
Dual High-Performance Emitting Colors: Ultra white delivers exceptional contrast in bright ambient light (e.g., factory floors), while pure green reduces eye strain during extended viewing (e.g., control room monitors)—perfect for applications like temperature/humidity indicators where data is checked frequently.
Even Light Distribution: Each segment is engineered to emit light uniformly, eliminating blurriness or uneven brightness that could lead to misreading critical values (e.g., confusing "25.5°C" with "23.5°C").
8-Digit Capacity: Supports multi-digit data display (e.g., -40.0°C to 120.0°C for temperature controllers), making it suitable for devices that require extended numerical ranges.
2. Energy Efficiency for 24/7 Operation
Engineered for minimal power draw—essential for devices that run continuously (e.g., process controllers)—this display offers:
Low Power Consumption & Extremely Low Current: Operates at a recommended forward current of 5-10mA per LED and a forward voltage of 2.8-3.2V per LED, reducing energy costs and extending the lifespan of battery-powered or wired devices.
High Efficiency: Converts electrical energy to light with minimal waste, ensuring consistent performance without overheating—critical for compact instrument panels with limited heat dissipation.
3. Industrial-Grade Reliability & Longevity
Built to withstand harsh operating conditions (e.g., temperature fluctuations, voltage variations), it delivers:
Stable Performance: Maintains consistent brightness and functionality across diverse environments—from cold storage (humidity indicators) to industrial workshops.
Long Lifespan: High-quality LED chips and robust construction minimize light decay over time, reducing maintenance costs and ensuring your devices operate reliably for years.
RoHS Compliance: Free from hazardous substances, meeting global environmental and safety standards—critical for OEM products sold in international markets.
4. OEM Flexibility & Hassle-Free Integration
Designed with OEM needs in mind, it simplifies your production and design workflow:
Customization Support: As an OEM product, it offers tailored modifications to match your device's unique requirements—no need to compromise on form or function.
Common Cathode Polarity: Works seamlessly with standard LED driver ICs, streamlining circuit design and reducing development time for your engineering team.
Easy Assembly: Compact dimensions (22×38×7mm) and intuitive pin labeling make installation quick, even in high-volume production lines—saving time and labor costs.
5. Versatility Across Precision Applications
While optimized for instrument panels, its performance and design make it suitable for a wide range of precision-focused use cases:
Temperature indicators & controllers
Humidity monitors
Process controllers
Industrial instrument panels
It adapts to any scenario where accurate, reliable multi-digit data display is essential.
