Title:
LAMINATED GLASS AND HEAD-UP DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/134775
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a laminated glass and a head-up display system. The laminated glass comprises an inner glass plate, a middle diaphragm and an outer glass plate, wherein the side of the inner glass plate that is away from the middle diaphragm is provided with a first transparent nano film, which is used for reflecting P-polarized light; the first transparent nano film comprises a laminate structure composed of a high-refractive-index material layer and a low-refractive-index material layer, which are sequentially deposited from the surface of the inner glass plate to the outside; a second transparent nano film is provided between the inner glass plate and the outer glass plate; the second transparent nano film comprises dielectric layers and electrically conductive layers; each electrically conductive layer is sandwiched between two dielectric layers; the refractive index of the high-refractive-index material layer is greater than or equal to 1.9; the refractive index of the low-refractive-index material layer is less than or equal to 1.8; and the P-polarized light reflectivity of the laminated glass when an incident angle is 65 degrees is greater than or equal to 16%. By means of the present application, both the P-polarized light reflectivity of laminated glass and the degree of smoothness of a P-polarized light reflection spectrum of the laminated glass can be improved, and the brightness and display comfort of a head-up display system using the laminated glass can be improved.
