Diffusion Film Products

Diffuser film is a critical optical thin film widely used in LCD, LED and Mini LED backlight modules. Serving as a key light homogenizing component in display systems, it eliminates bright spots, dark zones, light grain and uneven luminous phenomena by scattering and refracting light rays. By converting directional concentrated light from light guide plates and LED light sources into soft, uniform surface light, this optical film significantly improves screen flatness, clarity and visual comfort. It is universally applied in smart phones, tablets, LCD monitors, smart TVs, automotive displays, industrial control screens and commercial lighting panels, ensuring high-quality and glitch-free display performance for all kinds of terminal devices. Manufactured with high-purity optical PET substrate and advanced nano-particle coating technology, the diffuser film features excellent light transmittance and outstanding haze balance. Uniformly distributed microscopic diffusion particles carry o…
