Core Advantages

✅ Reliable Performance for Instrumentation Use
 
Delivering a stable 400 cd/m² brightness, this module provides clear, glare-free visibility for meters and gauges, ensuring readability in typical indoor and low-light conditions. The consistent illumination eliminates hotspots, making it ideal for precise instrument readouts.
✅ Compact, Thin Form Factor
 
At just 2.2mm thick, this ultra-thin backlight module is optimized for space-constrained instrumentation designs. The compact outer dimensions (76.97×4.93×2.2mm) fit seamlessly into standard 3.0-inch meter enclosures without requiring additional modifications.
✅ Simple Through-Hole Integration
 
The direct plug-in through-hole LED pins allow for easy soldering to PCBs, reducing assembly complexity and improving connection reliability. This design is ideal for mass production of meters and control panels, offering a cost-effective solution for standard instrumentation applications.
✅ Uniform, Low-Power Illumination
 
The precision-engineered light guide plate ensures even light distribution across the entire viewing area, eliminating uneven brightness and ensuring consistent readability across the display. The low-power LED design also helps reduce overall system power consumption, making it suitable for battery-powered instruments.
✅ Durable Industrial-Grade Build
 
Built to withstand continuous operation in typical indoor environments, this backlight module features a robust, flat-panel design with long-lasting LEDs. The through-hole pin configuration offers enhanced mechanical stability, reducing the risk of connection failure in vibration-prone industrial settings.
