Abstract
Certain example embodiments relate to a vehicle windshield with a head-up display system, including first and second spaced-apart substrates sandwiching a polymer-inclusive interlayer therebetween, and an anti-reflective coating provided on an exterior surface of the first substrate or an interior surface of the second substrate in opposite to the polymer-inclusive interlayer. An image source directing light rays towards one of the substrates, has an light emission profile showing the strongest light strength at a first wavelength, whereas the anti-reflective coating has a broad reflectance spectrum, showing the lowest reflectance at a second wavelength, which substantially matches the first wavelength.
