The direct-type backlight with light-emitting diodes (LEDs) is suitable for large-sized devices.

Our LED direct-lit backlight units are engineered to deliver superior brightness, contrast, and uniformity for large-scale displays, combining advanced zone dimming technology with robust thermal management. Designed for high-end TVs, commercial signage, and industrial monitors, these backlights feature densely packed LED arrays and precision optical components to achieve stunning visuals, energy efficiency, and long-term reliability—even in 24/7 operation scenarios.

Key Features & Technical Specifications

1. Core Components

• Light Guide Plate (LGP): Optimizes light diffusion from direct-lit LEDs using etched or printed micro-dot patterns.

  • Materials: High-transmittance PMMA or polycarbonate.

  • Thickness: 3.0mm–10.0mm (scalable for screen size).

• Diffuser Film: Eliminates hotspots and ensures uniform brightness across large panels.

  • Options: Multi-layer hybrid films for enhanced diffusion.

• Brightness Enhancement Film (BEF): Amplifies frontal luminance by 1.5x–2x with prismatic structures.

  • Gain: 1.5–2.0 (customizable per application).

• Reflector Sheet: Maximizes light efficiency with >97% reflectivity (aluminum or silver-coated PET).

• Structural Components:

  • Backplates: Aluminum alloy (excellent heat dissipation) or reinforced plastic (lightweight).
