| High Light | 4.3'' backlight module ，LED backlight module ，High Brightness custom backlight | ||
This 4.3-inch industrial-grade LED backlight module is engineered for high-performance factory automation and outdoor applications where exceptional brightness, reliability, and flexible integration are critical. Delivering an ultra-high luminance of 12000 cd/m² (12000 nits), it ensures crystal-clear visibility even under direct sunlight and intense factory lighting conditions. The FPC (Flexible Printed Circuit) PIN output enables vibration-resistant, space-saving installation, while its slim 3.55mm profile and precision dimensions (105.53×66.90×3.55mm outer size, 96.18×54.98mm viewing area) guarantee seamless compatibility with standard 4.3-inch industrial LCD panels. Ideal for industrial HMI, control panels, outdoor charging stations, portable rugged devices, and harsh-environment instrumentation systems.
Diagonal Size: 4.3 Inches
Overall Dimensions: 105.53 × 66.90 × 3.55 mm
Viewing Area (VA): 96.18 × 54.98 mm
Brightness: 12000 cd/m² (High Luminance, Sunlight Readable)
Connection: FPC (Flexible Printed Circuit) PIN Output (Yellow flat cable)
Light Source: Side-Emitting LED with precision-engineered light guide plate (LGP)
Typical Applications: Industrial control terminals, factory automation displays, outdoor charging station screens, portable rugged devices, and harsh-environment LCD systems
With industry-leading 12000 cd/m² luminance, this backlight completely eliminates glare and screen washout in bright environments. It ensures critical operational data remains perfectly readable even under direct midday sunlight, making it ideal for outdoor and high-intensity industrial settings.
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.
Engineered with exact outer and viewing area dimensions, this module fits standard 4.3-inch industrial LCD panels without any modifications. This reduces integration costs, shortens production lead times, and simplifies retrofitting of existing equipment.
At just 3.55mm thick, this module is optimized for the most space-limited industrial and portable device designs. Its compact form factor enables integration into slimline control panels and handheld rugged equipment without sacrificing illumination performance.
The precision-machined light guide plate delivers perfectly even light distribution across the entire viewing area, eliminating hotspots and brightness variations. The high-efficiency side-emitting LED design ensures long lifespan, low power consumption, and consistent performance across wide temperature ranges.
