What is PS diffuser plate ?
PS diffuser plate is a light diffusing plastic sheet made of high-quality polystyrene (PS) resin. It is widely used in led backlight units, display panels, and lighting fixtures, offering high light transmittance with excellent diffusion and uniform illumination.
Key Features of PS diffuser plate
✅ High Light Diffusion: Soft and uniform light distribution, eliminating LED hot spots.
✅ Good Light Transmittance: Transmittance up to 65-70% while maintaining effective diffusion.
✅ Excellent Thermal Stability: Suitable for LED lighting environments.
✅ Cut-to-Size Service: Custom dimensions and thickness are available on request.
✅ Cost-effective: PS diffuser sheets offer great performance at a lower cost than PC or PMMA.

Applications of PS diffuser plate
Our PS diffuser plates are widely used in various LED lighting and display systems, providing stable light diffusion effects to enhance overall brightness and uniformity:
💡 LED Panel Lights
In LED panel lights used in offices, shopping malls, hospitals, and other venues, PS diffuser plates effectively and uniformly scatter LED light sources, preventing glare and improving lighting comfort, making them an economical and efficient optical solution.
🖥️ TV Backlight Modules
In the backlight systems of LCD televisions, PS diffuser sheets can be used in conjunction with light guides and reflectors to ensure consistent screen brightness and clear, stable images, suitable for various direct-lit and edge-lit backlight designs.
📱 LCD Displays
Suitable for small and medium-sized LCD displays, industrial control screens, and other devices, PS diffuser panels provide stable optical performance, ensuring uniform brightness without dark areas or light leakage.
🚥 Signage and Lightboxes
PS diffuser panels can be used in ultra-thin lightboxes, directional signs, and LED advertising signs to effectively block point light sources, creating a smooth and bright illuminated surface that enhances the visual impact of advertisements.
🧴 Cosmetic Display Shelves with Lighting
In high-end display scenarios, PS light diffuser plates can soften lighting effects, highlight product display details, while ensuring uniform light distribution and no glare.
🏠 Indoor Lighting Panels
Widely used in decorative lighting systems for residential, hotel, and commercial indoor spaces, these panels are compatible with LED light sources to enhance the overall lighting quality and visual experience of the space.
