HEAD-UP DISPLAY WINDOW, AND VEHICLE

A head-up display (HUD) window includes a window glass and a projector (1). The window glass includes a glass layer (2) and a transparent nano coating (3). The transparent nano coating (3) is disposed on the glass layer (2). The projector (1) is configured to generate and project a projection light ray onto the window glass to form a projection image. A proportion of P-polarized light in the projection light ray is greater than or equal to 70%. The transparent nano coating (3) is capable of reflecting at least part of the P-polarized light incident. The window glass has a reflectivity for the P-polarized light greater than or equal to 5%. The window glass has a visible light transmittance greater than or equal to 70%. The window glass has a total solar energy transmittance less than or equal to 50%. The window glass in the disclosure has a good thermal insulation effect, thereby satisfying the usage requirements of thermal comfort.
