A laminate including: a first ply having a first surface and a second surface, where the first surface is an outer surface of the laminate; a second ply having a third surface facing the second surface and a fourth surface opposite the third surface, where the fourth surface is an inner surface of the laminate; an interlayer between the plies; and an enhanced p-polarized reflective coating positioned over at least a portion of a surface of the plies. When the laminate is contacted with radiation having p-polarized radiation at an angle of 60° relative to normal of the laminate, the laminate exhibits a LTA of at least 70% and a reflectivity of the p-polarized radiation of at least 10%. A display system and method of projecting an image in a heads-up display is also disclosed.
