More Information
Summary:The invention relates to the technical field of head-up display, in particular to a head-up display system utilizing a transparent nano-film for imaging display, and particularly provides a head-up display system comprising ultra-thin glass. The head-up display system comprises a projection light source, laminated glass and a transparent nano film, wherein the transparent nano film comprises at least two metal layers, the projection light source is used for generating P polarized light, the distance between the transparent nanometer film and the fourth surface is smaller than or equal to 1.86 mm, and the refractive index of the outer glass plate and/or the inner glass plate is 1.35-1.49. A clear head-up display image without visual ghosting can be generated, the requirements of high P polarized light reflectivity, high visible light transmittance and low fourth surface visible light reflectivity are met, and the defects of reddish color, yellow color and the like of the head-up display image can be eliminated
