Our advanced Electroluminescent (EL) Backlight Units deliver precise, uniform illumination for small reflective LCD displays, combining ultra-slim profiles, low power consumption, and exceptional durability. Designed for integration into compact devices, these backlights excel in applications demanding lightweight construction, consistent brightness, and long-term reliability. With customizable optical components—including light guides, diffusers, and prism films—our EL solutions ensure optimal performance for industrial, medical, and consumer electronics.
Key Features & Technical Specifications
1. Core Components
Light Guide Plate (LGP): Converts point-source light into uniform surface illumination using precision-etched or printed dot patterns.
Materials: PMMA, PC, or glass substrates.
Thickness: 0.3mm–2.0mm (customizable for compact designs).
Diffuser Film: Eliminates hotspots and ensures even light distribution.
Options: Micro-lens or bead-coated films.
Brightness Enhancement Film (BEF): Boosts frontal luminance by 1.5x–2x with prismatic microstructures.
Gain: 1.5–2.0 (adjustable per application).
Reflector Sheet: Minimizes light loss with >95% reflectivity (ESR or silver-coated PET).
Structural Components:
Backplates: Aluminum (for heat dissipation) or plastic (lightweight).
Frames: Customizable plastic/metal bezels for mechanical stability.
LED Mounts: Secure side-lit or direct-lit LED placement.
