Small Sized Reflective Backlight Unit EL Electroluminescent Backlight

Electroluminescent (EL) backlight is suitable for small-sized reflective LCD devices.

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.

2. Technical Highlights

• Light Source Options:

  • Consumer Electronics: Ultra-thin side-lit white LED arrays (0.5mm–3mm thickness).

  • Professional Displays: High-color-accuracy RGB LEDs or MiniLEDs (90%+ NTSC gamut).

  • Large-Scale Devices: Direct-lit LED modules with local dimming zones (100–1,500 nits).

• Power Efficiency: 3V–24V DC input, <1W power consumption for small units.

• Uniformity: >85% brightness uniformity (adjustable via LGP/diffuser tuning).

• Lifetime: 30,000–50,000 hours (depending on LED type and usage).

• Operating Temperature: -30°C to 80°C (industrial-grade options available).
