Description
3.5 Inch Square Industrial LED Backlight Module | 600 cd/m² with FPC Connector
Product Overview

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.

Key Specifications

Diagonal Size: 3.5 Inches (Square Format)

Overall Dimensions: 71.62 × 69.96 × 3.98 mm

Viewing Area (VA): 61.86 × 62.00 mm

Brightness: 600 cd/m² (Optimized for Indoor Industrial Use)

Connection: FPC (Flexible Printed Circuit) PIN Output (Yellow flat cable)

Light Source: Side-Emitting LED with precision-engineered square light guide plate (LGP)

Typical Applications: Compact industrial HMI, control panels, process indicators, small-scale instrumentation, and factory automation sub-displays

Core Features & Benefits
  • 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.
