Abstract: A windshield includes an outer glass, a polymer interlayer, and an inner glass. The inner glass has a third surface and a fourth surface opposite the third surface. The third surface faces the polymer interlayer. The windshield has an information collection region and a non-information collection region. An enhanced reflection coating is provided on the fourth surface. The enhanced reflection coating covers the information collection region and the non-information collection region. The enhanced reflection coating is configured to improve a reflectivity of the non-information collection region for P-polarized light of 380 nm˜ 780 nm. A dielectric coating is further provided in the information collection region. The dielectric coating disposed on a side face of the enhanced reflection coating away from the fourth surface.

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: This disclosure relates to the field of head-up display (HUD) technology, and more particularly to an HUD system with a transparent nano film for image display. Specifically, an HUD system including ultra-thin glass is provided in the disclosure. The HUD system includes a projection light source, and laminated glass, and a transparent nano film. The transparent nano film includes at least two metal layers. The projection light source is configured to generate P-polarized light. The laminated glass provided with the transparent nano film has a maximum reflectivity Rmax and a minimum reflectivity Rmin for the P-polarized light that has the incident angle ranging from 45° to 72°, where Rmax/Rmin ranges from 1.0 to 2.0.

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.
