More Information
Summary: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. In the disclosure, a clear HUD image without visual ghosting can be generated, so that requirements of high reflectivity for P-polarized light, high transmittance for visible light, and low reflectivity for visible light of the fourth surface may be satisfied, thereby rendering an HUD image in neutral color, and enriching the color of the HUD image to achieve full-color display.
