This 3.5-inch long-narrow LED backlight module is purpose-built for strip-style instrumentation and digital meter applications, delivering consistent, uniform illumination for elongated display panels. Featuring an optimized brightness of 1000 cd/m², it provides clear, glare-free readability in indoor and low-to-moderate ambient light environments. The FPC (Flexible Printed Circuit) PIN output offers flexible routing and vibration-resistant installation, while its slim 2.86mm profile and precision dimensions (91.19×35.00×2.86mm outer size, 85.15×24.023mm viewing area) ensure perfect compatibility with standard 3.5-inch strip-type meter and instrument LCD panels. Ideal for industrial strip gauges, digital energy meters, automotive status indicators, medical equipment sub-displays, and various precision measurement devices.
Engineered exclusively for elongated strip-style instrumentation displays, this backlight provides perfectly uniform illumination across the entire 85.15×24.023mm viewing surface, eliminating edge shadowing and brightness variations that could compromise accurate data reading in narrow-format meters.
Calibrated to deliver a balanced 1000 cd/m² luminance, this backlight ensures crisp, legible meter readouts without causing eye fatigue during extended monitoring periods. It is perfectly suited for indoor industrial environments and shaded outdoor locations.
The FPC flexible PIN output enables versatile routing and superior shock absorption compared to rigid connectors. This design reduces connection failures in dynamic environments and simplifies integration into custom enclosure layouts.
With a minimal thickness of just 2.86mm, this module is designed to fit into the most space-constrained strip-style instrumentation enclosures. Its compact form factor allows for seamless integration into modern, slimline meter and control panel designs.
Equipped with high-efficiency side-emitting LEDs, this backlight delivers excellent energy efficiency, making it suitable for both mains-powered and battery-operated instrumentation devices. The robust construction guarantees reliable performance and extended service life under continuous operation.
