Product Overview
The Hollow-Cavity LED Backlight relies on a cavity-based optical structure instead of a conventional solid light guide plate. LEDs are fitted inside the dedicated illumination space, while reflective components redirect light toward the LCD panel.
Internal cavity dimensions, reflective materials and LED arrangement can all be configured to match display size and optical targets. This gives equipment manufacturers greater freedom to develop backlight systems for outdoor and industrial scenarios.
Bolong LCD provides customized engineering support for hollow-cavity backlight assemblies, covering structural design, LED configuration and electrical matching.
Key Features
Hollow Optical Cavity: Uses an air-gap illumination structure with reflective components.
Flexible Light Distribution: LED positioning and reflective surfaces can be configured for different panel sizes.
Thermal Design Considerations: The cavity structure allows engineers to evaluate airflow and heat dissipation requirements.
Outdoor Display Adaptability: Designed for display systems requiring application-specific brightness solutions.
Custom Mechanical Structure: Supports different shapes, dimensions and mounting configurations.
Integrated Engineering Support: Backlight and LCD compatibility can be evaluated together.
