Custom-Shaped Backlight Units (EL, CCFL & LED Edge-Lit)
(Irregular-Form Lighting Solutions for Innovative Designs)
We specialize in custom-shaped backlight units that break free from
traditional rectangular constraints, enabling innovative product
designs across industries. Utilizing EL (Electroluminescent), CCFL
(Cold Cathode Fluorescent Lamp), and LED edge-lit technologies, our
free-form backlights deliver uniform illumination for curves,
circles, cutouts, and complex geometries. Ideal for devices
requiring unique aesthetics or space-optimized lighting, these
solutions combine precision engineering with optical excellence.
| Type | EL Backlights | CCFL Backlights | LED Edge-Lit |
|---|---|---|---|
| Thickness | 0.3–1.0mm (Ultra-thin) | 3.0–8.0mm | 1.0–4.0mm (Slim) |
| Brightness | 30–100 cd/m² | 5,000–10,000 cd/m² | 300–1,500 cd/m² |
| Uniformity | Excellent | Very Good | Good (with LGP tuning) |
| Power | 50–200V AC, <100mA | 500–1,000V AC, 3–8W | 3.3–24V DC, 0.5–5W |
| Lifetime | 5,000–8,000 hours | 30,000–50,000 hours | 50,000+ hours |
| Shapes | Any 2D complexity | Simple curves/cutouts | Moderate complexity |
Consumer Electronics:
Smartwatches (EL circular backlights), VR headsets (LED crescent shapes).
Medical Devices:
Endoscope displays (CCFL ring lights), Diagnostic panels (EL custom icons).
Automotive:
Dashboard indicators (LED curved backlights), HVAC controls (EL symbols).
Industrial:
Machine status panels (CCFL gauges), IoT sensors (EL irregular outlines).
Retail & Signage:
Logo lighting (LED cutouts), Interactive kiosks (CCFL arches).
EL Backlights:
✅ Pros: Ultra-thin (<1mm), flexible substrates, 360° uniformity.
❌ Cons: Low brightness, limited lifespan, AC voltage required.
CCFL Backlights:
✅ Pros: Extreme brightness, high uniformity, wide temperature range.
❌ Cons: High voltage, thicker profiles, fragile tubes.
LED Edge-Lit:
✅ Pros: Energy-efficient, slim designs, 50,000+ hour lifespan.
❌ Cons: Complex LGP design for irregular shapes, hotspot risks.
Materials: Flexible PCBs (EL), PMMA/PC light guides (LED), borosilicate glass (CCFL).
Optical Control:
Micro-dot patterns (LGP) for brightness zoning.
Custom diffuser films to eliminate hotspots.
Prism sheets (BEF) for +1.5–2x gain.
Structural Support:
Laser-cut aluminum/plastic frames.
Waterproof sealing (IP65–IP68).
EMI shielding for sensitive environments.
End-to-End Design: Optical simulation, prototyping, and validation.
Samples: Fast-track prototyping with "Priority Delivery" (subject to design complexity).
Production Lead Time: 4–6 weeks (scalable for high-volume orders).
Lifelong Support: Technical guidance for thermal management, driver compatibility, and optical tuning.
