Touch Screen Surface Enhancements

Anti-Glare (AG)

When surrounding glare makes display readability difficult, anti-glare (AG) coatings utilize diffusive properties to fragment the ambient light
off the surface, using the concept of constructive interference of light. Diffusion works by scattering specular reflections into a wide viewing
cone, making these undesirable reflected images and glare blurred to the eye.
AG coatings use either diffused particles or etching on the glass surface and can enhance viewing performance. EDT currently provides
two standard types of AG coating, both with superior glare reduction for glass cover lens.

Anti-Reflection (AR)

Using the concept of destructive interference of light, anti-reflective (AR) coatings utilize film structure over the glass surfaces that vastly
improve the efficiency of the optical performance by increasing transmission, enhancing contrast, and eliminating ghost images.

1. The transmission rate could reach up to 92% for single side one layer AR coating and 94% for double side two layers AR coating.
2. AR coating is vulnerable against finger prints, therefore extra layer of AF costing is always required.

Anti-Fingerprint (AF) 

Anti-Fingerprint (AF) coating is using nano-scale material which has excellent water & oil repellency to make the glass surface have a smooth touch, and prevent the glass surface from contamination such as smudging or staining, making the glass surface extra slippery and easy to clean.
