This 3.0-inch LED backlight module is purpose-built for instrumentation and meter applications, offering reliable, uniform illumination in compact spaces. Designed with direct through-hole LED pins, it enables simple, solderable integration into control panels, meters, gauges, and small industrial displays. With a stable brightness of 400 cd/m², it provides clear, consistent visibility in indoor and low-light environments, making it ideal for industrial and consumer instrumentation use cases.
Diagonal Size: 3.0 Inches
Outer Dimensions: 76.97 × 4.93 × 2.2 mm
Viewing Area (VA): 64.6 × 39.00 mm
Brightness: 400 cd/m² (Standard Luminance for Instrumentation)
Connection: Through-Hole Direct Plug-in LED Pins
Light Source: Edge-Lit LED with precision light guide plate for even illumination
Applications: Instrumentation meters, industrial gauges, control panel displays, consumer electronics indicators, and compact device screens
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.
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.
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.
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.
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.
