Laminated glass and head-up display system

Abstract

The embodiment of the invention provides laminated glass and a head-up display system, and the laminated glass comprises an inner glass plate, a middle membrane and an outer glass plate, and one side, far away from the middle membrane, of the inner glass plate is provided with a first transparent nano-film used for reflecting P polarized light. The second transparent nano-film comprises at least one laminated structure formed by 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 arranged between the inner glass plate and the outer glass plate, the second transparent nano-film comprises dielectric layers and conductive layers, and each conductive layer is clamped between the two dielectric layers; the refractive index of the high-refractive-index material layer is larger than or equal to 1.9, the refractive index of the low-refractive-index material layer is smaller than or equal to 1.8, and the P polarized light reflectivity of the laminated glass is larger than or equal to 16% when the incident angle The P polarized light reflectivity of the laminated glass and the smoothness of the P polarized light reflection spectrum can be improved at the same time, and the brightness and the display comfort of a head-up display system adopting the laminated glass can be improved.

Description

technical field [0001] The present application relates to the field of head-up display technology, in particular to laminated glass and a head-up display system. Background technique [0002] Head-up display system HUD (Head Up Display) is more and more widely used in automobiles and other fields, and the setting of laminated glass is one of the key points in the design of head-up display system. [0003] At present, the existing laminated glass usually has a coating that can reflect P-polarized light on the inner glass plate, but because the high-refractive index material used in the coating has a low refractive index, it is difficult to obtain a coating that meets the requirements of the head-up display system. P-polarized light reflectivity required for high-quality use; at the same time, the simple superposition of two coatings used in existing laminated glass cannot make the P-polarized light reflectance spectrum of laminated glass smooth enough, and the non-smooth P T...

[0003] At present, the existing laminated glass usually has a coating that can reflect P-polarized light on the inner glass plate, but because the high-refractive index material used in the coating has a low refractive index, it is difficult to obtain a coating that meets the requirements of the head-up display system. P-polarized light reflectivity required for high-quality use; at the same time, the simple superposition of two coatings used in existing laminated glass cannot make the P-polarized light reflectance spectrum of laminated glass smooth enough, and the non-smooth P The reflection spectrum of polarized light will greatly affect the display effect of the projector image, and will seriously affect the driving comfort of the car with the head-up display system

[0004] That is to say, the existing laminated glass has problems such as low reflectivity of P polarized light and poor smoothness of P polarized light reflection spectrum.
