Head-up display glass and head-up display system

Abstract

The invention discloses head-up display glass and a head-up display system. The head-up display glass comprises an outer glass plate, an inner glass plate, a middle layer, a transparent conductive film and a reflection increasing film, the outer glass plate comprises a first surface and a second surface which are opposite to each other, the inner glass plate comprises a third surface and a fourth surface which are opposite to each other, and the second surface is opposite to the third surface. The middle layer is arranged between the second surface and the third surface, the transparent conductive film is arranged on the second surface or the third surface, and the reflection increasing film is arranged on the fourth surface. The reflectivity of the transparent conductive film to the P polarized light is not less than 6%, the reflectivity of the reflection increasing film to the P polarized light is not less than 10%, the reflectivity of the head-up display glass to the P polarized light is not less than 15%, light of the P polarized light of an image entering human eyes can be increased, the reflectivity of the head-up display glass to the P polarized light is improved, and the display definition of an HUD image can be improved. The display effect is enhanced.

Description

technical field [0001] The invention 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] With the development of the automobile industry, the head-up display function of the front windshield of the automobile has become an important consideration factor for consumers to purchase automobiles. Conventional head-up display glass is coated with a reflective film layer on the glass, and the image projected by the projection unit is reflected on the film layer and enters the human eye. [0003] However, in order to ensure that the light transmittance of the conventional head-up display glass meets the national standard, the reflectivity of the reflective film layer is limited, so that the image received by the human eye has low brightness and appears blurred, and the display effect is not good. Contents of the invention [0004] The object of the present invention is to provide a...

Problems solved by technology

[0003] However, in order to ensure that the light transmittance of the conventional head-up display glass meets the national standard, the reflection rate of the film layer with the reflective function is limited, so that the image received by the human eye has low brightness and appears blurred, and the display effect is not good.
