ABSTRACT:
Certain example embodiments relate to a head-up display system for a vehicle having a windshield. First and second substantially parallel spaced-apart substrates sandwich a polymer-inclusive interlayer. An anti-reflective coating is provided on a surface of one of the first and second substrates. The anti-reflective coating is arranged so as to optically remove or block at least some of light rays produced by an image source of the head-up display system so as to reduce the occurrence of multiple images being produced by the image source. The anti-reflective coating is provided on a surface of the first or second substrate opposite the polymer-inclusive interlayer. In certain example embodiments, the polymer-inclusive interlayer may include polyvinyl butyral and/or may have a substantially uniform thickness.
