Problems solved by technology

In the existing front windshield, in order to realize the function of the head-up display, a polyvinyl butyral (PVB) layer with a wedge-shaped structure is often used as the middle layer of the windshield. However, the preparation process of the PVB layer with a wedge-shaped structure is complicated and expensive. High, and poor applicability, different specifications of PVB layers are required for different models
Therefore, it is necessary to provide a new type of head-up display glass to solve the problems of high cost and poor applicability of the existing head-up display glass

Abstract

The invention provides head-up display glass which comprises laminated glass, the laminated glass comprises a first surface and a second surface which are opposite to each other, the second surface comprises a display area and a non-display area, the display area is provided with a first nano film, the first nano film comprises at least one first high-refractive-index layer and at least one first low-refractive-index layer which are sequentially stacked from the second surface to the outside, the refractive index of the first high-refractive-index layer is 1.9-2.7, and the refractive index of the first low-refractive-index layer is 1.3-1.8. The reflectivity of the display area to P polarized light incident at 55-75 degrees is larger than or equal to 10%, and the reflectivity of the non-display area to visible light incident at 0-10 degrees is smaller than the reflectivity of the display area to the visible light incident at 0-10 degrees. The head-up display glass is low in cost, clear in head-up display image and less in visual interference, so that the driving safety and comfort in the driving process are ensured. The invention further provides a head-up display system.

Description

technical field [0001] The present application relates to the technical field of head-up display, in particular to a head-up display glass and a head-up display system. Background technique [0002] Head-up display (HUD, Head Up Display) is more and more widely used in cars. The vehicle-mounted head-up display system uses the principle of optical reflection to reflect important driving information on the front windshield. In the existing front windshield, in order to realize the function of the head-up display, a polyvinyl butyral (PVB) layer with a wedge-shaped structure is often used as the middle layer of the windshield. However, the preparation process of the PVB layer with a wedge-shaped structure is complicated and expensive. High, and poor applicability, for different models need to use different specifications of the PVB layer. Therefore, it is necessary to provide a novel head-up display glass to solve the problems of high cost and poor applicability of the existin...
