Hud system with transparent nano film for image display
The granted patent US12061337B2 describes a head-up display (HUD) system that integrates a projection light source, laminated glass, and a transparent nano film. The laminated glass consists of an outer glass panel, an inner glass panel, and an intermediate adhesive layer. The transparent nano film, positioned between the second surface of the outer panel and the third surface of the inner panel, contains at least two metal layers designed to reflect P-polarized light. The system is configured to generate P-polarized light at incident angles between 45° and 72°, achieving a reflectivity of at least 6% for this light. The distance between the nano film and the inner glass panel is limited to 1.86 mm, and the reflectivity ratio of maximum to minimum values (Rmax/Rmin) is maintained between 1.0 and 2.0.
Additional claims detail various aspects of the HUD system, including the wedge-shaped cross-section of the adhesive layer, the thickness of the metal layers in the nano film, and the materials used for the glass panels. The system may also incorporate a light-filtering component with a transmittance of at least 80% for P-polarized light and a projection control system that utilizes a color-filtering processing algorithm. The patent further specifies the optical properties of the laminated glass, including its absorptivity and reflectivity for near-infrared and blue-green light, as well as the refractive indices of the glass panels. Overall, the patent outlines a sophisticated HUD system designed to enhance visibility and performance through advanced optical engineering.
