Head Up Display (HUD) systems can rely on optical film embedded in or affixed onto automotive windscreen. If these optical films have an orientation access, such as reflective polarizing films, then the optical axis of those films is generally required to align to the windscreen which (in turn) is aligned to the HUD light projection engine in the automotive dash.
