| High Light | 3.1 Inch LED Backlight ，Industrial LED Backlight ，22000cd/M2 led tv led backlight | ||
This 3.1-inch industrial-grade LED backlight module is engineered for extreme high-brightness applications where uncompromising sunlight readability and compact design are critical. Delivering an industry-leading ultra-high luminance of 22000 cd/m² (22000 nits), it ensures crystal-clear visibility even under direct midday sunlight and intense factory lighting conditions. The FPC (Flexible Printed Circuit) PIN output enables vibration-resistant, space-saving installation, while its ultra-thin 2.54mm profile and precision dimensions (71.08×51.46×2.54mm outer size, 63.06×47.62mm viewing area) guarantee seamless compatibility with standard 3.1-inch industrial LCD panels. Ideal for compact industrial control terminals, outdoor sensor displays, portable rugged devices, and harsh-environment instrumentation systems.
With an unmatched luminance of 22000 cd/m², this backlight completely eliminates glare and screen washout in the most extreme 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.
At just 2.54mm 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.
Engineered with exact outer and viewing area dimensions, this module fits standard 3.1-inch industrial LCD panels without any modifications. This reduces integration costs, shortens production lead times, and simplifies retrofitting of existing equipment.
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.
