The optical functional film substrate is a critical component of an FPD. This substrate is constructed by forming a dielectric thin film, a metal thin film, or a combination of both on an optical element or transparent substrate. This approach helps to control both light transmission characteristics and electrical characteristics. Sanyo Vacuum Industries’ varied line of optical functional film substrates satisfies a wide variety of needs.
Anti Reflection Film (AR)
The antireflection film substrate has contributed to the development of the innovative portable digital assistant (PDA). We manufacture highly reliable antireflection substrate products for full control of surface reflectance. For more details, click on the following link.
Dielectric Semi-transmittance Film
A dielectric semi-transmittance film is formed from a multilayer arrangement of a high-refraction material and a low-refraction material. This configuration helps achieve a low-absorbing half color or cold mirror. For more details of the features of the mirrors, click on the following link.

Antifouling Film
Antifouling film prevents fouling of the surfaces of optical elements. We are committed to employing all our manufacturing techniques to the production of antifouling film to help ensure PDAs retain an aesthetically pleasing appearance.
