  • No, anti-reflective coatings are not matte. They work by producing destructive interference in a target band of wavelengths right at the surface of the coated material from front and rear reflections. Because the effect is wavelength specific, they tend to tint the colour of the reflection, as well, allowing you to tell when they’ve been applied.

    Not really. It has to be enough brighter than the reflection that it’s not visually disturbing. And that criterion depends on what’s displayed: a high contrast image is much more robust than a bright single colour which is much more robust than a dark single colour.

    Screens nowadays have anti-reflective coatings to make the brightness of a reflection far, far less than the actual light source if you looked directly at it.
