Abstract: A Head up display system includes a projection light source, laminated glass, and a transparent nano film. The transparent nano film includes at least one laminated structure consisting of a high refractive-index layer and a low refractive-index layer, where the high refractive-index layer and the low refractive-index layer is deposited sequentially outwards from the surface of the inner glass pane. The projection light source is configured to generate P-polarized light. A ratio of near-red light reflectivity R1 at wavelengths ranging from 580 nm to 680 nm of the laminated glass with the transparent nano film to near-blue light reflectivity R2 at wavelengths ranging from 420 nm to 470 nm of the laminated glass with the transparent nano film is R1/R2=1.0˜2.0.

Abstract: A head-up display (HUD) window includes a window glass and a projector. The window glass includes a glass layer and a transparent nano coating. The transparent nano coating is disposed on the glass layer. The projector 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 is capable of reflecting at least part of the P-polarized light incident on the window glass. 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%.

Abstract: Head-up display glass is provided. The head-up display glass includes laminated glass that has a first surface and a second surface opposite to the first surface. The second surface includes a display region and a non-display region. A first nano-coating disposed in the display region includes at least one first high-refractive-index layer and at least one first low-refractive-index layer that are alternately stacked. Each first high-refractive-index layer has a refractive index ranging from 1.9 to 2.7. Each first low-refractive-index layer has a refractive index ranging from 1.3 to 1.8. The display region has a reflectivity greater than or equal to 10% for P-polarized light incident at an angle ranging from 55° to 75°. For visible light incident at an angle ranging from 0° to 10°, a reflectivity of the non-display region is less than a reflectivity of the display region. A head-up display system is further provided.
