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 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 laminated glass provided with the transparent nano film has the maximum reflectivity Rmax and the minimum reflectivity Rmin for the P polarized light within the incident angle of 45-72 degrees, and Rmax/Rmin is equal to 1.0-2.0. 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, the head-up display image presents a neutral color, and the color of the head-up display image is richer so as to realize full-color display.

Description

Technical field: [0001] The invention relates to the field of head-up display technology, in particular to a head-up display system using transparent nano-film imaging display, and specifically provides a head-up display system including ultra-thin glass. 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 can greatly enhance driving safety and improve driving experie...
