Products Description

Direct-Lit LED Backlight is developed for LCD panels that require evenly distributed illumination across a relatively large viewing area. With LEDs arranged behind the display, this design creates a flexible foundation for optical uniformity, brightness tuning and thermal management. Bolong LCD develops customized LED layouts, optical components and driver configurations for industrial displays, commercial equipment and other large-format LCD applications.
Product Overview
For large LCD panels, the arrangement of light sources strongly influences the overall illumination effect. Direct-Lit LED Backlight Modules place LEDs behind the display rather than along its edges, allowing light to blend and spread across the panel via an optical mixing structure.
This design brings greater flexibility when building backlight systems for large display areas. LED spacing, optical distance and diffuser configuration can be tuned according to the panel dimensions and required brightness performance.
Bolong LCD develops custom direct-lit backlight solutions for equipment manufacturers looking for reliable illumination systems for their LCD products. From LED layout to mechanical structure, each module can be assessed against its intended application.
