Head-up displays, HUD, have been in commercial use for several decades in diverse applications seeking to minimize driver distraction while at the same time dealing with the overload of information available from the various vehicle systems. The disclosure provides an HUD coating glazing that when used in conjunction with a projecting means emitting p-polarization light, results in a bright, high contrast image with substantially no secondary images. The coating of the present disclosure is deposited on at least a portion of the glass surface of the windshield, or any other vehicle glazing, allowing for multiple displays and supporting augmented reality, the coating comprising at least one first dielectric layer being Si-based layer, a functional metallic layer, a second dielectric layer with an index of refraction between 1.4 and 2.0 and at least one third dielectric layer having scratch-resistance and environmentally protective properties.
