YG OptiDiff™ is a high-performance LED light diffuser panel designed specifically for LED lightboxes, illuminated signs, and display lighting applications. Compared to standard white acrylic sheets, YG OptiDiff™ offers superior uniform light diffusion, effectively eliminating hotspots and improving brightness consistency. This advanced acrylic light diffuser enhances visual comfort and creates a more professional and refined lighting effect.
Manufactured using optically clear cast acrylic, YG OptiDiff™ panels are available in a wide range of thicknesses from 3mm to 50mm, meeting the diverse needs of signage, displays, and architectural lighting. These panels have passed the rigorous ASTM G155 UV 3000-hour accelerated weathering test, demonstrating exceptional UV resistance and long-term durability. Even in harsh outdoor environments, they resist yellowing, hazing, and optical degradation, making them the ideal solution for both indoor and outdoor LED light diffuser applications.
When selecting acrylic materials for LED lightboxes or backlit signage, it is essential to choose panels that offer uniform light diffusion and hotspot elimination. Below is a full comparison between standard white cast acrylic and YG OptiDiff™—our advanced LED diffuser acrylic panel.
| Feature | Standard White Cast Acrylic | YG OptiDiff™ LED Diffuser |
|---|---|---|
| Application Focus | Basic light transmission only | Engineered for LED lighting with uniform diffusion |
| Light Source Appearance | Visible hotspots and LED dots | Diffusion particles scatter light evenly; no glare |
| Typical Use Cases | Backboards, general signage | LED lightboxes, outdoor signs, illuminated ads |
| Surface Quality | Uneven surface, optical defects possible | Ultra-smooth surface with consistent light diffusion |
| Processing Flexibility | Basic cutting and forming | Same fabrication as acrylic; available in 3–50mm thickness |
| Weather & UV Resistance | No UV protection; prone to yellowing and hazing | ASTM G155 UV 3000h tested; long-lasting outdoor performance |
Unlike conventional “white acrylic + white dye” sheets, YG OptiDiff™ LED diffuser panels are specially formulated with optical-grade diffusion particles blended directly into the raw material. This results in brighter, softer, and more uniform light diffusion, effectively solving common issues such as LED hotspots and glare.
YG OptiDiff™ is one of our flagship products for the Japanese LED signage and lighting market. For years, we have partnered with leading Japanese architectural lighting and sign manufacturers to co-develop customized diffuser solutions that meet the highest standards in color consistency and optical performance.
How are your acrylic diffuser sheets manufactured? Are they cast or extruded?
Our diffuser sheets are made using the cast acrylic process, not extrusion. This allows for better optical clarity, durability, and custom thickness options—especially for thicker panels.
When should I choose a diffuser acrylic sheet instead of a milky white acrylic sheet?
If you need more uniform light diffusion, better LED hotspot concealment, and reduced glare, a diffuser acrylic sheet is a better choice than traditional milky white acrylic. It is especially suitable for lightboxes, backlit displays, and high-end lighting applications.
What thickness options are available? Can you produce thicker sheets?
We offer standard and custom thicknesses ranging from 3mm to 50mm, and can produce ultra-thick diffuser panels on request for specific structural or optical applications.
Are your diffuser sheets suitable for outdoor use? Will they turn yellow?
Yes. Our products are made with UV-resistant Mitsubishi raw materials and have passed the ASTM G155 3000-hour UV weathering test, ensuring excellent outdoor durability with no visible yellowing over time.
Can you produce based on custom size and color?
Absolutely. We provide OEM/ODM services, including custom sizes, shapes, and Pantone color matching to meet your specific project requirements.
What’s the difference between a diffuser sheet and a light guide panel (LGP)?
A diffuser sheet is designed to scatter light for uniform brightness, while an LGP channels light from the edge across the surface, often used in edge-lit signage and displays. They serve different optical purposes.
Can your diffuser sheets be laser-cut or CNC-machined? Will they crack?
Yes, our sheets are compatible with laser cutting and CNC machining. Made from cast acrylic, they have high impact resistance and maintain edge quality during processing without cracking.
What certifications do your products meet? SGS? UL? UV?
Our diffuser sheets are certified by SGS for various safety and performance standards, with certain models tested to UL 94 (HB and V-0) flame ratings and UV resistance. Contact us for specific certificates.
Are your diffuser panels used by Japanese brands? Do you have actual cases?
Yes. Our diffuser sheets are used by top Japanese signage companies and other global lighting brands. We can provide real-world case studies upon request.
Can you provide samples for testing? What’s the lead time?
Yes, we offer samples for light testing or evaluation. Lead time typically ranges from 7 to 14 working days, depending on stock and customization needs.
What’s the difference between cast and extruded acrylic sheets?
Cast acrylic is made by pouring liquid MMA into molds, resulting in better optical clarity, thickness stability, and customization flexibility. It’s ideal for high-end applications and thicker sheets.
Extruded acrylic is made by continuously pushing acrylic through rollers — it’s more cost-effective but may have less optical precision, higher internal stress, and limited thickness options.
For diffuser sheets, we use cast acrylic to ensure consistent light performance and high durability.
