Diffusive LGP
The Diffusive Light Guide Plate (Diffusive LGP) is an advanced optical solution designed to deliver smooth, uniform illumination through bulk light diffusion rather than surface laser engraving. By embedding precisely controlled diffusive particles within the PMMA substrate, the light is scattered evenly throughout the panel, producing consistent brightness with minimal visual artifacts.
This technology eliminates the need for laser dot patterns or silk-screen printing, making Diffusive LGPs especially suitable for compact, medium-sized panels and applications where simplicity, reliability, and visual comfort are critical.

- Design Flexibility: Easily adaptable to different shapes and layouts.
- Dual Light Input: Supports single-sided or double-sided edge lighting.
Design & Integration Guidelines
Recommended Panel Size
Diffusive LGPs perform best in small to medium formats, particularly for panels with a width not exceeding 600 mm, where uniformity can be maintained without surface extraction patterns.
LED Configuration
- Optimized for edge-lit LED arrangements.
- Works well with both single-edge and dual-edge input designs.
- Simpler LED layout compared to laser-etched LGPs.
Diffuser Usage
Optional diffusers can be used to further soften luminance or meet glare requirements.
In many applications, no additional front diffuser is required.
