Polycarbonate Diffuser Sheets
Premium light diffusion technology for professional LED light boxes. Eliminates hotspots, ensures uniform lighting.
Professional Diffuser Sheet
Advanced Bayer technology for optimal light distribution
Advanced Light Diffusion Technology
Sophisticated chemical particle and resin matrix creates uniform light scattering through continuous refraction, reflection, and diffusion
How Diffusion Technology Works
Light Refraction
Chemical particles bend incoming light rays at multiple angles, breaking up direct beam patterns
Multiple Reflection
Light bounces between particles and resin matrix, creating even distribution across the entire surface
Uniform Scattering
Final result is soft, even illumination that eliminates visible LED hotspots and harsh shadows

Customer Reviews
David Chen
Advertising Agency Creative DirectorPerfect diffusion for our premium LED displays
We've used various materials for light boxes over the years, but these PC diffuser sheets are in a different league. The light distribution is incredibly uniform - no more visible LED hotspots that made our displays look unprofessional. Client satisfaction has increased significantly since switching to these panels.
Maria Rodriguez
Shopping Mall Operations ManagerExcellent durability for high-traffic areas
Replaced all our directional signage with these diffuser panels 18 months ago. They still look brand new despite constant use in a busy mall environment. The impact resistance is impressive - we've had shopping carts bump into them with no damage. Much better than the acrylic panels we used before.
Robert Kim
Sign Shop OwnerSuperior to acrylic in every way
Made the switch from acrylic to these PC diffuser sheets for all our light box projects. The difference is night and day - better light diffusion, no cracking issues, and customers love the professional appearance. Yes, they cost more upfront, but the reduced warranty claims and happy customers make it worthwhile.
Frequently Asked Questions
Yes, we offer custom cutting to any size up to 2100mm width. While white is standard for optimal light diffusion, other colors are available on request for special applications.
No, our sheets feature dual-side UV protection and maintain optical properties for 10+ years of outdoor use without significant yellowing or performance degradation.
Thickness depends on structural requirements and light box size. Haze level affects diffusion - higher haze (90-95%) gives more uniform diffusion but slightly lower total light transmission. Our technical team can recommend optimal specifications.
PC diffuser sheets typically cost 20-40% more than acrylic initially, but offer superior durability, impact resistance, and optical consistency, resulting in lower total cost of ownership.
Use proper mounting systems with adequate ventilation. Avoid over-tightening screws to prevent stress cracking. For large panels, ensure even support distribution. Our installation guide provides detailed instructions for optimal results.
We provide a 10-year limited warranty covering UV degradation, yellowing, and optical performance. Manufacturing defects are covered for 2 years. Warranty terms vary by application and environmental conditions.
