3.5 Inch Square Industrial LED Backlight Module 2700K-3500K Warm White

This 3.5-inch square industrial-grade LED backlight module is engineered for compact industrial control and instrumentation applications, delivering reliable, uniform illumination for small-format square LCD panels. Featuring an optimized brightness of 600 cd/m², it provides clear, glare-free readability in indoor industrial environments. The FPC (Flexible Printed Circuit) PIN output enables vibration-resistant, space-saving installation, while its precision dimensions (71.62×69.96×3.98mm outer size, 61.86×62.00mm viewing area) ensure seamless compatibility with standard 3.5-inch square industrial LCD panels. Ideal for compact industrial HMI, control panels, process indicators, and small-scale instrumentation systems.

• Optimized 600 cd/m² Brightness for Industrial Environments

  Calibrated to deliver a balanced 600 cd/m² luminance, this backlight ensures crisp, legible readouts without causing eye strain during extended operation in factory and industrial settings. It is perfectly suited for indoor control rooms and equipment enclosures.

• Precision Square Dimensional Compatibility

  Engineered with exact square outer and viewing area dimensions, this module fits standard 3.5-inch square industrial LCD panels without any modifications. This reduces integration costs, shortens production lead times, and simplifies equipment retrofitting.

• Vibration-Resistant FPC Connector Design

  The flexible FPC PIN output provides superior shock and vibration absorption compared to rigid connectors, significantly reducing connection failures in dynamic industrial environments. The compact yellow flat cable allows for flexible routing in space-constrained enclosures.

• Robust Industrial-Grade Construction

  Built with a reinforced frame and mounting tabs, this backlight withstands continuous operation and mechanical stress common in industrial environments. The high-efficiency side-emitting LED design ensures long lifespan, low power consumption, and consistent performance across wide temperature ranges.

• Uniform, Flicker-Free Illumination

  The precision-machined square light guide plate delivers perfectly even light distribution across the entire viewing area, eliminating hotspots and brightness variations. The flicker-free LED driver design also reduces operator eye strain during prolonged monitoring.
