Embodiment 1-5 and comparative example 1

[0058] The present invention obtains Examples 1-5 and Comparative Example 1 by designing the film structure of the transparent nano-film and adjusting the value of T1 / T2 of P-polarized light incident on the transparent nano-film.

[0059] Laminated glass: green glass (2.1mm) / PVB (0.76mm) / white glass (2.1mm) / transparent nano film

[0060] Transparent nano film: white glass / SiN(41.4nm) / TiOx(48.9nm) / SiN(13.3nm) / SiO2(112nm)

Embodiment 1

[0061] Example 1: T1 / T2 of incident P polarized light=0.8

Embodiment 2

[0062] Example 2: T1 / T2 of incident P polarized light=0.7

Abstract

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 capable of eliminating the defects of redness, yellowness and the like of a head-up display image. The head-up display system comprises a projection light source, laminated glass and a transparent nano film, the transparent nano film comprises at least one laminated structure of a high refractive index layer and a low refractive index layer which are sequentially deposited outwards from the surface of an inner glass plate, and the projection light source is used for generating P polarized light. The ratio R1/R2 of the near-red light reflectivity R1 to the near-blue light reflectivity R2 of the laminated glass with the transparent nano film is 1.0-2.0. According to the invention, the defects of reddish color, yellow color and the like of the head-up display image can be eliminated, the head-up display image presents neutral color, the color of the head-up display image is richer so as to realize full-color display, full-color display can be realized at lower cost, and the selection cost of the projection light source is reduced.

Description

Technical field: [0001] The invention relates to the technical field of head-up display, in particular to a head-up display system using transparent nano-film imaging display, and specifically provides a head-up display system capable of eliminating defects such as reddish and yellowish images of the head-up display. Background technique: [0002] Head Up Display (HUD, Head Up Display) systems are increasingly deployed on cars, so that important driving information, such as speed, engine revolutions, fuel consumption, tire pressure, navigation, and information from external smart devices can be displayed in real time. It is displayed in the driver's field of vision on the front windshield, so that the driver can see the driving information without looking down, so as to avoid distracting the attention of the road ahead; at the same time, the driver does not have to look at the distant road and the nearby Adjusting the eyes between the instruments can avoid eye fatigue, which...
